Podcasts about fgf

Fibroblast Growth Factor-1 (FGF-1) is being discussed as a potential regenerative therapy for Parkinson's disease. Some claim it may protect or even restore dopamine-producing neurons. But what does the science actually say? In this episode, we break down: • What FGF-1 is and how it works • Why growth factors are being explored in Parkinson's disease • How FGF-1 compares to decades of research on Glial cell line-derived neurotrophic factor (GDNF) • What animal studies show — and what human trials do not yet show • The risks, unknowns, and delivery challenges • How to think critically about regenerative claims Parkinson's disease urgently needs disease-modifying therapies.  Growth factors are biologically plausible and scientifically interesting — but promising is not the same as proven. This video is an evidence-based look at where FGF-1 stands today. If you're living with Parkinson's, caring for someone who is, or simply trying to understand the science behind emerging therapies, this episode is for you.

Dr Deb Muth 00:03Well, welcome back to Let’s Talk Wellness Now. I am your host, Dr. Deb. And what is the most talked-about peptides in functional medicine? aren’t actually FDA approved. Not because they don’t work, but because no one’s funded the research to prove it yet. The truth is, some of the compounds that dominate wellness forums, BPC-157, TB-500, thymosin beta-4, epitalin, occupy a fascinating space between breakthrough science and unregulated experimentation. In today’s episode, we’re stepping into that grey zone, the world of investigational peptides, to separate mechanism from marketing. I’m going to walk you through the science that actually shows and where it stops, how to evaluate claims when human data don’t yet exist, and the quality, purity, and safety red flags that you need to recognise. Dr Deb Muth 01:06I created it in a previous episode, so go check that one out. And why honesty is the most important prescription in peptide medicine. If you’ve ever wondered whether these research-only peptides are the frontier of healing or the next functional medicine fad, this episode is for you. So grab your cup of tea or coffee, get comfortable, and let’s talk about what it really means to use peptides that are promising but still under investigation. So we’re going to break just for a second here and have a word from our sponsor. It is because of them that we stay on the air. So thank you for this. And we will be right back. Did you know sweating can literally heal your cells? Infrared saunas don’t just relax you. They detox your body, balance hormones, and boost mitochondrial energy. I’m obsessed with my Health Tech sauna. And right now, you can save $500 with my code at healthtechhealth.com slash dr-muth-req-25. Dr. Deb Muth 02:15All right, guys, welcome back. Let’s dive into investigational peptides, the evidence gap. So the following peptides we’re about ready to discuss are extensively in integrative, functional, and regenerative medicine circles. They may have intriguing mechanisms and promising preclinical data. However, they lack FDA approval, and the evidence quality varies dramatically. from interesting preliminary research to essentially no human data at all. And this distinction is really critical for maintaining scientific integrity. So let’s talk about immune-modulating peptides. There’s thymus and alpha-1, and this is an international story on the thymic peptides. Thymusin alpha-1, known as TA1, is marketed internationally as zidaxin. Dr. Deb Muth 03:16It’s a 28-amino acid polypeptide originally isolated from thymusin fraction 5, which was extracted from bovine thymus tissue. Modern production uses synthetic peptide synthesis. The thymus gland is located behind the sternum and is the primary site for T cell maturation, and thymic peptides like TA1 play roles in human system development and regulation. Now, I love thymus peptides. I love thymus glandular products. I’ve used thymus glandular products for decades. Ground-up animal thymus gland is basically what it is. There are a couple of different supplement companies that I’ve used over the years that are amazing with this. And they do a fantastic job, and they really do help to support the immune system. So when thymus peptides came out, it was really exciting because it took the whole idea of thymus support to a new level. Dr. Deb Muth 04:17The mechanism actually behind the thymus in alpha-1 is complex and involves multiple aspects of immune function. At the cellular level, TA1 enhances T cell maturation and differentiation, particularly the development of helper T cells and cytotoxic T cells. It modulates T cell receptor expression and can influence the balance between Th1 cell-mediated immunity and Th2 humoral immunity responses. And it also enhances the natural killer cell activity and modulates dendritic cell function, which are critical for antigen presentation. and initiation of adaptive immune responses. And on the cytokine level, TA1 influences production of interleukin-2, IL-2, interferon gamma, IFN-γ, and interleukin-10, IL-10. Dr. Deb Muth 05:19These create immune modulatory rather than simple immune stimulatory effects. This is a very important distinction because TA1 appears to help balance the immune system rather than simply ramping this up, which theoretically makes it safer in conditions where immune overstimulation would be a problem, such as an autoimmune disease. Hashimoto’s, autoimmune, lupus, Sjogren’s, any of those autoimmune diseases, we don’t want to overstimulate their immune system. So you want to use a product like this that’s non-stimulating. Now, the regulatory status on TA1 is geographically variable and represents one of the challenges in discussing this peptide with patients. It is not FDA-approved in the United States. However, it is approved in several other countries for specific conditions. Dr. Deb Muth 06:19In Italy, it’s approved for the treatment of chronic hepatitis B and hepatitis C. In China, it’s approved for chronic hepatitis B and adjunct immune compromised patients receiving vaccinations or suffering from certain infections. It has an orphan drug designation in the United States for certain cancer indications, but its designation does not constitute approval. It simply provides regulatory incentives for further development. So the evidence base for thymosin alpha-1 is substantial in some areas but comes primarily from non-US populations and research groups, which creates challenges in evaluating quality and generalizable information. So in hepatitis B and C, multiple clinical trials, many conducted in China and Italy, have examined TA1 as an adjunct to antiviral therapy. Dr. Deb Muth 07:21A meta-analysis by Wu and colleagues published in the Journal of Viral Hepatitis in 2013 examined 23 randomized controlled trials, including over 2,000 patients with chronic hepatitis B. The analysis found that combining TA1 with nucleoside analogs like LAMVDUDE or an and TCAVAR improved the hepatitis antigen seroconversion rates by HBV DNA clearance compared to its nucleoside analogs alone. And the effect sizes were modest but statistically significant, with the HBE-AG seroconversion rates improving from about 24% with antivirals alone to 38% in combined therapy. Now in hepatitis C, early trials before the development of direct-acting antivirals showed that TA1 combined with interferon alpha improved sustained virological responses, and compared to interferon alpha, Dr. Deb Muth 08:30Furon alone, particularly in difficult-to-treat populations like those with a genotype one or a high viral load. However, the advent of highly effective direct acting antivirals that achieve SRV rates, sorry, SVR rates exceeding 95%, the role of TA1 in hepatitis C has become less clear. Now in sepsis and critical illness, more recent interest has focused on TA1 in severe cases of sepsis and septic shock. Ren and colleagues published a systematic review and meta-analysis in the Frontiers of Immunology in 2022, analyzing 18 randomized controlled trials, including 1787 patients with severe sepsis or septic shock the pooled analysis showed that ta1 administration was associated with reduced 28-day mortality relative risk at 0.70 meaning a 30 reduction in mortality compared to the standard care alone and the effect appeared Dr. Deb Muth 09:39most pronounced in patients with sepsis-induced immunosuppression measured by HLA-DR expression in monocytes. Now, this is amazing because going forward, we’re going to talk about something that’s commonly known as cytokine storm. Now, cytokine storm really became apparent since 2020 with the viral infection that we’re dealing with in the world today. But they were already looking at this kind of cytokine storm produced by sepsis or sepsis-induced immunosuppression. And it triggered this hyperinflammatory response called the cytokine storm. And many patients who survived the initial phase of the immune suppressed stata, characterized by a T cell exhaustion, reduced antigen presentation, and increased susceptibility to secondary infections. Thymusin alpha-1, TA1, may help restore this immune competence in this phase. However, it’s important to note that patient selection and timing are critical. Dr. Deb Muth 10:43Giving this immune stimulant during a hyperinflammatory phase could theoretically worsen outcomes. So you don’t want to give it to them while they’re in the flare up or the sepsis or the infection, but given to them during the immunosuppression phase afterwards might be beneficial. Now there is also some cancer immunotherapy that we see with TA1 and has been studied as an adjunct in cancer treatment with the hypothesis that it could enhance immune surveillance and response to tumors. And a comprehensive review of Garci and colleagues published in Expert Opinion on Biological Therapy in 2007 examined multiple trials in melanoma, lung cancer, hepatocellular carcinoma, and other malignancies. And the results were mixed. Some trials showed improvement in the immune parameters, increased CD4 in T-cells. improved lymphocyte proliferation responses and some actually showed trends toward improved progression free survival but overall survival benefits were inconsistent and the heterogeneity of the cancer types treatment protocols and outcome measures makes a definitive conclusion difficult as a vaccine adjunct several studies particularly from china have examined ta1 as an adjunct to enhance vaccine responses Dr. Deb Muth 12:11in immune-compromised populations, including the elderly, dialysis patients, and transplant recipients. The rationale is sound. These populations often mount suboptimal antibody responses to vaccines, and TA1’s immune-enhancing effects might improve protection. There are small trials. They have shown improvement in seroconversion rates of hepatitis B vaccines and influenza vaccine in these populations. And though large-scale confirmatory studies are limited, there is a possibility here. Now, on their safety profile, one of the appealing aspects of thymusin alpha-A TA1 is that it’s apparently favorable safety profile in clinical trials. There are some injection site reactions with a little redness, a mild discomfort, and most commonly reported adverse effects. is that their severe adverse events attributable to TA1 have been rare in published trials. However, comprehensive long-term safety data are limited Dr. Deb Muth 13:13And theoretically, concern exists that immune modulation could potentially trigger or exasperate autoimmune conditions in susceptible individuals. Though this hasn’t been clearly demonstrated in clinical trials, integrative medicine considerations for integrative practitioners concerning the thymus and alpha-1, several factors require careful thought. First, sourcing and quality control are critical concerns. Since it’s not FDA approved, TA1 available in the United States typically will come from a compounding pharmacy or an international supplier with variable quality assurance. And pharmaceutical grade product with certificates of analysis showing purity, sterility, and endotoxin testing is essential, but it is readily available from many of these companies. Second, patient selection matters immensely. TA1 should be considered in complex cases where conventional approaches have been insufficient, such as chronic viral infections not responding adequately Dr. Deb Muth 14:21to standard antivirals, post-viral syndromes with evidence of immune dysfunction, cancer patients with immune suppression in consultation with oncology, and it should generally be avoided in active autoimmune disease unless there’s a compelling rationale and close monitoring. Now, TA1 is not a standalone therapy. In cases of chronic viral infection, Comprehensive immune support includes addressing nutritional deficiencies, optimizing vitamin D levels to be between 50 and 80, adequate zinc, selenium, and vitamin A, optimizing gut health since 80% of our immune function is in the gut, you need to optimize gut function. Managing stress from the HPA access dysfunction, chronic cortisol elevation, suppression, and immunity, ensuring adequate sleep, immune memory consolidations during sleep, addressing any metabolic dysfunction, insulin resistance, repairs in the immune function, and the bottom line on thymus and alpha-1 is Dr. Deb Muth 15:26is that it represents legitimate medicine in other countries with a substantial evidence base in specific contexts, but it remains experimental in the U.S., and practitioners using it should provide comprehensive, informed consent about its regulatory status, evidence quality, and source verification. while ensuring it’s part of comprehensive protocols. It is not a magic bullet. And again, what you’re gonna hear me say quite often here is that many of these peptides should be used in conjunction with something else. They should not be used alone. And can peptides be stacked? The answer is yes, they can. So if somebody has an insulin resistance, or a metabolic dysfunction, they can tier TA1 with a GLP-1 like terzepatide or semiglutide. That is not a problem to do that. You need to just work with a practitioner that understands how to do that effectively. So let’s look at BPC-157. Dr. Deb Muth 16:26This is a phenomenon I love BPC-157. Let’s separate it from marketing to actual mechanism of actions here. So BPC-157 stands for Body Protection Compound 157. It is a chain of 15 amino acids that are described as a partial sequence of body protection compound, a protein found in human gastric juice. It has become one of the most hyped peptides in regenerative medicine inside the athletic performance and biohacking communities with claims ranging from healing tendons and ligaments to repairing gut lining or reversing organ damage. The challenge is separating the legitimate mechanisms of science from the marketing hype. The proposed mechanism of BPC-157 are biologically plausible and intriguing. The research suggests that it may influence several growth factor pathways, including vascular endothelial growth factor, VEGF, which promotes new blood vessel formation and has improved better supply of blood flow to injured tissues, theoretically accelerating healing. Dr. Deb Muth 17:40It may also affect fibrous blast growth factor, FGF, and transforming growth factor beta, TGF beta pathways. both involved in tissue repair and remodeling. And some studies actually suggest that BPC-157 modulates inflammatory cascades, potentially reducing excessive inflammation while promoting the resolution phase that allows tissue rebuilding. Now I want to talk just a few moments here about these different tests that we’re talking about tgf beta veg f for those of you who are in our mold world you are very familiar with these uh lab tests we do this to see if you have a mold exposure what’s happening to your body and it’s been very challenging to try to heal this part of the mold illness and manipulate these VEGFs and TGF betas. And so with the fact that BPC helps us modulate this inflammatory cascade, BPC can be very helpful in the world of mold or mycotoxin illness in repairing those parts of the body that have been damaged by the mycotoxins. Dr. Deb Muth 18:48Now there is animal research on BPC-157. It is extensive and primarily from a research group led by pre-drag, oh, I can never say these names, Cyrek at the University of Zagreb in Croatia. Published studies in animal models have shown accelerated healing in a remarkable variety of injury types. A 2011 paper by Chang and colleagues in the Journal of Applied Physiology demonstrated that BPC-157 improved therapy tendon healing in rats with Achilles tendon injuries, and the treated rats showed increased tendon outgrowth, better cell survival in the injured area, enhanced cell migration to the injury site, and improved biochemical strength of the healed tendon compared to controls. Multiple other animal studies have shown similar promising effects. Ligament tears, healing faster in rabbits, muscle damage recovering more quickly in rodent models, gastric ulcers healing in rats given experimental induced ulcerations, inflammatory bowel lesions improving in mouse models of colitis, and even bone to tendon healing showing enhancement in animal studies. Dr. Deb Muth 20:02The breadth of injury types showing benefit in preclinical models explains the enthusiasm of this peptide. However, this is critical. These animal studies, primarily in rodents and rabbits, animal models of injury healing don’t reliably translate to human clinical outcomes. And the doses used in these animal studies when converted to human equivalent doses vary widely. And optimal human dosing is completely unknown at this point. it is all considered experimental and perhaps most importantly there are essentially no peer-reviewed controlled clinical trials in human published in humans published in major medical journals in a 2001 review of arthroscopy and the journal of arthroscopic and related surgery specifically examined in the evidence of bpc 157 and other peptides in musculoskeletal medicine The authors concluded bluntly that BPC-157 lacks evidence from randomized controlled trials and has an unknown safety profile in humans. Dr. Deb Muth 21:09 They emphasized that the jump from animal data to recommending peptides for humans use bypasses the fundamental requirement for Phase I safety studies, Phase II dose-finding studies, and Phase III efficacy trials that would establish whether BPC-157 actually works in humans and whether or not it’s safe. The absence of human safety data is particularly concerning given BPC-157’s proposed mechanisms. Peptides that influence growth factor signaling and angiogenesis could theoretically have off-target effects. Uncontrolled angiogenesis, for instance, is a hallmark of cancer progression. Tumors require blood vessel formation to grow beyond a certain size. And while there’s no evidence that BPC 157 promotes cancer, The complete absence of long term human safety studies means we simply don’t know. This isn’t fear mongering. It’s acknowledging uncertainty and uncertainty exists and understanding that if you’re choosing to use peptides like BPC 157, you are doing it in an experimental model. Dr. Deb Muth 22:17We’re experimenting with the doses that are being used. And there is potential for it to cause cancer cells in your body to grow. And you need to be aware of this and understand the risks that you’re taking when you’re using an investigational or off label use peptide. Now, quality control issues with BPC also exist. It’s not FDA approved for any indication in the US. It’s not approved in any major regulatory jurisdiction worldwide. It’s marketed as a research chemical explicitly to bypass FDA oversight. And commercial sources selling BPC-157 range from compounding pharmacies, which have some quality standards but are not FDA inspected. You can take that for what you want to believe on that one. to overseas suppliers operating with absolutely no quality assurance whatsoever. If you are choosing to use BPC-157, you have to understand who’s manufacturing it for you, where you are getting it from, how pure it is. Dr. Deb Muth 23:26You want to make sure that you have the certificate of analysis and that it does not contain bacterial endotoxins that can contaminate the peptide or degrade the peptide and cause other issues for you. So when you talk about peptides with patients regarding BPC-157 or if you’re listening to this and you’re already using BPC-157 or other peptides, that are quote-unquote not for human consumption, an evidence-based response acknowledges both the appeal and the limitations. And you want to talk about the animal data that’s definitely showing some progress and some potential, but we don’t know what we don’t know in humans. If people are willing to take that risk, that is up to them to do that. But using BPC right now is experimental and people need to be aware of that. Are there evidence-based alternatives for patients with tendon or ligament injuries? Dr. Deb Muth 24:26And there are. There’s PRP, which has been studied in multiple randomized controlled trials. for conditions like lateral epicondylitis, tennis elbow, Achilles issues, patellar issues, knee issues. However, I want to caution you on this too. So the study that was done by Cox and colleagues in muscles, ligaments, and tendons in the Journal of 2014 showed modest benefits in pain and function compared to controls. And though the effects vary by injury type, PRP preparations can be helpful. You have to understand that a lot of times when people are doing PRP injections in their office, they are not doing it exactly the same way it was done in the study. And not to mention, if you’re using your own PRP to heal a ligament or a tendon or help your arthritis and you’re 60 or 70 years old, That is not good quality protein rich plasma. It is old protein rich plasma. And you’re not going to see necessarily the same benefits that you would see if you were using placental tissue or umbilical tissue. Dr. Deb Muth 25:33You also want to address the nutritional deficiencies or support that’s needed for connective tissue healing. And these are collagen peptides dosed at 15 grams a day. And this has been shown in a study by Shaw and colleagues in the American Journal of Clinical Nutrition in 2017 to augment collagen synthesis when combined with intermittent loading. Vitamin C is also an essential cofactor for collagen production and stabilization of collagen structure at a dose of around 500 to 1000 milligrams a day to support this process. You also need to have good adequate intake of copper and zinc. These are cofactors in collagen. Silica is also important. This comes from horsetail extract. This provides additional support as well. So more importantly, I think remembering that rehabilitation matters as well. Doing these protocols without doing some rehab is not going to get you where you want to go. Dr. Deb Muth 26:33There’s a research study by Alfredson and others for Achilles tendinopathy using the control lengthening of muscle tendon units under load to promote tendon remodeling and healing. These protocols have solid evidence and cost nothing beyond professional guidance from a physical therapist. They are important for patients seeking cutting edge regenerative approaches. Stem cell therapies, growth factors, concentrates derived from patients’ own tissues like PRP. These have a lot of good endogenous materials and they have good safety profiles. BPC-157 represents the perfect example of how promising Preclinical science gets marketed far beyond the evidence and it may eventually prove to be valuable. I think it will. But right now that determination does require some human studies and hopefully with the administration that we have right now and Bobby Kennedy, we will actually start to see some of that occur. Now the next peptide I want to talk about is TB4, thymus and beta-4. Dr. Deb Muth 27:36This is a wound healing peptide. It is a 43 amino acid peptide that’s naturally present in virtually all human cells except red blood cells. It’s actually one of the most abundant peptides in the human body, particularly concentrated in blood platelets, wound fluid, and many tissues. It’s naturally ubiquity makes it mechanistically interesting. The body wouldn’t produce it in such abundance if it didn’t serve a function. So the primary role of TB4 involves building G-actin. It’s a form of monomeric actin. And it’s structural protein that forms the microfilaments within the cells, providing cellular structure and enabling cell movement. TB4 prevents from F-actin filaments. I’m not going to talk too much about this. It’s really critical for wound healing as cells need to migrate into the injury sites. Dr. Deb Muth 28:37so the cell shape changes and the cellular response to the injury. So think of this as though you tore your meniscus and the body created all this TB4 to come to that injury to try to heal that site. That’s exactly what the TB4 is doing inside the body when there’s an injury. It’s been shown in research to help produce new blood vessel formation, promote endothelial cells, It helps modulate inflammatory cytokines, potentially reducing TNF-alpha, IL-1, and possibly protecting in programmed cell death, which we call apoptosis. And some studies suggest that it is cardioprotective in its effects in animal models of myocardial infarction, so heart attack, and neuroprotective in other models for brain injury. Now, these remain to be preliminary, but they are being seen. So the regulatory status on TB4 can create some confusion. Dr. Deb Muth 29:40The natural TB4 molecule itself is not FDA approved as a drug. However, TB4 based drug candidates called RGN259, formerly TB4, has been in the development by regen tree for corneal injuries of the dry eye disease. And as of recent updates, this drug is completed phase three trials for its neurotrophic keratopathy, severe corneal condition. But the FDA approval is still pending. So that means that the most advanced TB4-based pharmaceuticals hasn’t yet crossed the finish line for approval. The commercial peptide market further muddies the picture with TB500, which is often described as the synthetic fragment of TB4. However, this extract’s relationship between TB500 and TB4 varies depending on the source. Dr. Deb Muth 30:41So some claim that TB500 is identical to TB4, but positions 1 through 4 suggest it’s a different fragment. and the quality control across suppliers is not existent. So this confusion is part of why recommending TB500 becomes problematic for practitioners and patients, often because they aren’t certain what molecule they’re actually getting. The evidence base for TB4 in humans is limited, primarily to eye research, and the studies from Sohn’s and colleagues published in journals like Vitamins and Hormones in 2016 have examined topical TB4 for corneal injuries and neurotrophic keratopathy, dry eye, and other surface diseases. Now, these studies showed some promise in promoting this, and there is, however, a topical application to the cornea that is vastly different from a systemic injection. So for systemic use in wound healing, musculoskeletal issues, Dr. Deb Muth 31:42cardiac protection, neuroprotection, human clinical trials. There is scarce to non-existent evidence in humans. Most of the evidence remains in animal models or cell culture studies. And a review by Flip and colleagues in the Journal of Investigational Dermatology in 2006 detailed TB4’s effects on the matrix remodeling during wound repair in animal models, showing effects on collagen disposition, granulation, tissue reformation, and wound contraction. Another review by Ho and colleagues in expert opinion on biological therapy in 2007 discussed TB4’s potential in tissue regeneration and regenerative medicine, but noted the field remained largely blank. preclinical. So this is really important again to understand that there is just not enough human data. So there is a concern with cell division and migration. This theoretically exists Dr. Deb Muth 32:45for the potential effects on cancer cells, which would also rely on migration and division and other intended consequences of disrupting normal cellular architecture. These aren’t proven risks, but they are unexplored questions that we need to be aware of when we’re using peptides. This can cause cancerous tissue to grow. Very similar to what we talked about with BPC-157. These are also sold as research chemicals. There is no FDA oversight. So purity, potency, contaminations all still exist for these peptides. Now from an integrative perspective, the natural presence of TB4 in wound fluid and its biological roles in healing are legitimate science. in presence does not equal therapeutic utility. The body tightly regulates where and when and how much TB4 is present through natural production and bypassing that regulation with external dosing may or may not cause us to have beneficial or introduce risk. Dr. Deb Muth 33:49So we need to know that this is experimental use. Those people who are seeking wound healing and tissue repair the evidence-based approach of the body’s own capacity to heal is huge definitely want to be increasing your protein intake optimizing your zinc copper vitamin c and vitamin a and then managing glucose is really important during this time as well so let’s talk about a fun topic now and that’s growth hormone secretagogues this is the anti-aging hype machine these peptides in this category are things like semoralin ipameralin cjc 1220 1295 and others and among the most aggressively marketed in anti-aging and longevity medicine they all share a common goal stimulating the pituitary gland to release more growth hormone and the appeal is understandable. GH levels decline with age, and this decline is associated with increased fat mass, decreased lean muscle, reduced bone density, and other aspects of aging. Dr. Deb Muth 34:55The other times we’ll see growth hormone levels decline significantly is with chronic illness, and the logic is to restore youthful GH levels and youthful physiology. Now, semirelin from an FDA approved diagnostic to compound anti-aging product. Semirelin is a 29 amino acid peptide representing the first 29 amino acids of the full 44 amino acid human growth releasing hormone, GHRH. We talked about this on another episode of the podcast. And you can go back and listen to that one a little bit if you want. This fragment contains the complete biological activity of the full GHRH molecule and it binds to GHRH receptors in the anterior pituitary and stimulates growth releasing peptides, growth hormone releasing peptides. Semirelin was previously FDA approved as diagnostic testing of growth hormone secretion, essentially, to determine if the pituitary could still respond to GHRH stimulation in patients being evaluated for growth hormone deficiency. Dr. Deb Muth 36:06However, the manufacturer was discontinued and there was no longer an FDA approved semirelin product on the market in the United States. What exists now is semirelin available from compounding pharmacies used off label for anti-aging, body composition, and general growth hormone optimization purposes. This represents a significant gray area. Again, compounding medications serve a very important role, but they need to meet certain recommendations and regulations, as we’ve talked about in the past. You want to make sure that your compounding pharmacy that you’re obtaining semirelin from is qualified to do that, that they are doing best practices, and that you’re getting a good product. The theoretical advantage to semirelin over direct growth hormone administration is that it preserves more of the physiological growth hormone secretion patterns. Natural GH is released in pulses, primarily during sleep, not as a continuous elevation. Dr. Deb Muth 37:07So semirelin stimulates the pulses rather than providing a constant super physiological growth hormone level. And that pulsatile pattern is thought to reduce some of the side effects and metabolic concerns that we have with continuous growth hormone exposure. However, the evidence supporting semirelin for anti-aging and body composition in healthy adults is minimal. Most of the data comes from studies conducted in the 1990s when the FDA approved product existed. Not that that means it’s bad. We have drugs that have been in the market for over a hundred years that are still there, that still have the research and are still being used successfully and safely today. So we don’t want to let that really make us think that this product isn’t safe. So a 2006 review from Walker in Clinical Interventions of Aging suggested that semirelin might be a better approach than direct GH for adult onset growth hormone insufficiency, but they do acknowledge that the evidence was limited. Dr. Deb Muth 38:12And although we don’t have any large scale trials that we can examine for semirelin’s efficacy, it is now commonly prescribed. And the optimal dosing for anti-aging purposes is still unknown. It is considered experimental and it does vary from person to person, but it is still unstudied. The effects on cancer risk, cardiovascular disease, metabolic dysfunction over long time periods are also still unknown. I would argue that the side effects or the risk factors of not having growth hormone are equally as bad as the unknowns that we have here. We’re not looking to try to get super physiological doses. We’re trying to restore youthful GH levels. Typically, we’re not trying to restore back to a 20-year-old. We’re trying to restore back maybe 10 years. That is a better way of doing this. And I think that’s important for people to understand. Now, ipamirelin is the ghrelin mimicker. Dr. Deb Muth 39:12Ipamirelin is a pent-up peptide, five amino acid, that acts as a growth hormone secretagogue receptor, a GHS-R agonist. It mimics the action of ghrelin, the hunger hormone, that also stimulates growth hormone release. The proposed advantage over earlier secretagogues is that ipamirelin stimulates growth hormone release without significantly affecting cortisol, prolactin, or other glucose things, which can be increased by growth hormone secretagogues. The regulatory status is clear. Ipamirelin is not FDA approved for any indication. It’s sold as a research chemical. Human evidence is thin. It’s limited to single dose studies examining how quickly it’s absorbed and metabolized with minimal data on dosing and clinical outcomes. Now there are marketing claims for ipamirelin and they are extensive. Dr. Deb Muth 40:13It increases lean muscle mass, it decreases body fat, it improves sleep quality, faster recovery from workouts, enhanced injury healing, better skin quality. The evidence supporting these claims in humans is not available we don’t have it these are claims that are made by the effects that we know from growth hormone so it’s not necessarily a bad thing we know what growth hormone does we know growth hormone does all of these things if ipamorelin is a precursor to that it will obviously help improve those things making that correlation of what growth hormone does So there are safety concerns that mirror the same as any other growth hormone elevating therapy. It can cause fluid retention, joint pain, carpal tunnel syndrome, insulin resistance, glucose intolerance, and theoretically, can it increase calcium? cancer risks? It can because IGF-1 promotes cell proliferation and can inhibit apoptosis in cancer cells. Now remember, your body makes IGF-1. Dr. Deb Muth 41:15If it’s not making enough of it, that’s a problem. If it’s making too much of it, That’s a problem. So just understand that if you are adding these things, and especially in elevated doses, you are taking a potential risk. So there is also now CJC 1295 is a modified GHRH analog of 30 amino acid peptide based on GHRH structure, but with modifications. So it includes the addition of drug affinity complex, DACC, DAC, which involves conjugation with a small albumin binding molecule, dramatically extends the peptide’s half-life from minutes to as much as potentially a week or more. And this creates sustained growth hormone elevation rather than that pulsatile release. There are actually two versions of this. There’s CJC 1295 with DAC, longer acting version, and CJC 1295 without DAC, which is essentially a shorter duration of semirelin. Dr. Deb Muth 42:19And so when we’re comparing products, it is… only the difference between long acting and short acting. The human evidence for CJC 1295 is limited to a single published phase one study by Techman and colleagues in the Journal of Clinical Nutrition and Metabolism in 2006. And the study involves 18 healthy young adults showed that CJC 1295 with DAC produced a sustained elevation of GH and IGF-1 lasting several days after the injection. That’s essentially the entire published human evidence of this peptide. There are no phase two studies examining optimal dose. So that is all considered experimental. And there is no phase three studies examining clinical efficacy. So the sustained GH levels created by CJC 1295 with DAC raises specific concerns because the natural GH secretion It goes up and down, up and down, up and down. Dr. Deb Muth 43:19And that constant elevation may have a different metabolic and cellular effect. And we just really don’t know what that’s going to be yet. So we can understand that elevated IGF-1 levels can theoretically increase cancer concerns and metabolic risks. So rather than always injecting peptides, which are very expensive… You can do other things. And there was a study by Hartman and colleagues in the Journal of Clinical Endocrinology and Metabolism in 1992 that demonstrated the 48-hour fast increased integrated growth hormone secretion five-fold through increased GH levels. Now, the problem with this is fasting for 48 hours is a challenge. And how long is it going to increase the growth hormone secretion without causing issues? Or in general, how long is it going to go up? Dr. Deb Muth 44:19So we have to be cautious about that as well. Sleep optimization is non-negotiable. The majority of growth hormone secretion occurs during sleep, slow wave sleep, typically the first sleep cycle, and poor sleep quality or insufficient sleep typically. can dramatically affect your growth hormone levels. And then high intensity interval training, HIIT resistance training can stimulate growth hormone as well. This was seen in a study by Godfrey and colleagues in sports medicine in 2003 and was examined in exercise-induced growth hormone responses to athletes. So we definitely see these kinds of things. So let’s talk about some longevity peptides now. These expand the telomere. So there’s epitalin and epithalamin and when these are used in anti-aging they can produce some amazing results. Dr. Deb Muth 45:22So epitalin is a synthetic terapeptide, just four amino acids. It was originally synthesized as a simplified version of epithalamine. a pineal gland extract containing multiple peptides. The synthetic four amino acid version was created to isolate what researchers believed might be the active anti-aging component. The mechanism produced for epitalin centers on telomere and telomerase, Telomeres are protective caps at the end of the chromosomes consisting of repetitive DNA sequencing. And every time a cell divides, telomeres shorten slightly because DNA polymers cannot fully replicate the ends of the linear chromosomes. So this progressive shortening acts as a molecular clock. After 50 or 70 divisions, the telomeres become critically short, triggering a cellular senescence. Dr. Deb Muth 46:22This telomere shortening is one mechanism of cellular aging and telomeres in the enzyme that can rebuild telomeres by adding these caps back onto the end of the chromosome. It’s active in stem cells, germ cells, and unfortunately in about 85 to 90% of the cancer cells. In most adult somatic cells, telomerase is inactive or present at very low levels, allowing the telomeres to shorten with division. The research on epitalin suggests it might activate this telomeres act telomeres process primarily from a research group led by Vladimir in Russia. Vladimir Kavasan in Russia. He is a huge peptide researcher or was he passed away with publications dating back to the early 2000s and a study published in bio gerontology in 2000 by Kavasan Dr. Deb Muth 47:25and colleagues examined the effect of epitalin on the lifespan of fruit flies, and they treated fruit flies that showed a modest increase in mean and maximum lifespan compared to its controls by approximately 10 to 15% lifespan extension in some experimental groups. And there were other studies in 2003 that examined epitalamine in a female Swiss-derived mouse. This was done by Ann Simove and colleagues. And the researchers reported that epitalin treatment was associated with increased lifespan as well. And the most cited mechanistic work comes from cell culture studies. And that is also Cavason’s group that published this research in 2003, showing increased telomeres activity in cultured somatic cells again. More recently, between 20 and 25, the series of publications have continued to explore epithelial effects on telomere dynamics in cell cultures. Dr. Deb Muth 48:32So there is a lot of research that’s been done. The mass majority has been done on epithelin. And most of it has been done by a single research group in Russia. There is some restrictions on some of the cell culture data that we’re seeing. And it does show that epithelin sometimes can be described as a regulating hormone. Carcadian rhythm for melatonin production, which is derived by the penile extracts. And however the evidence for this affects minimally and mechanistically unclear, the pineal gland primarily functions as melatonin secretion in that light-dark cycles. So Epithalin or epitalin is not FDA approved. It is not approved for any major regulatory jurisdiction. It is sold as a research chemical only. Dr. Deb Muth 49:33So you need to follow the same safety profiles that we’ve talked about in other episodes and in today’s episodes. And when we’re talking about epithalin, and we’re excited about it being an anti-aging science, we should balance this with the honesty and the evidence of the quality of that evidence. We don’t know its safety effect. We don’t know if it’s going to increase the risk of cancer. We can’t verify that. And we need to be using it in an experimental use of unknown risks only. Of course, diet, physical activity, stress management, sleep quality, all of those things are important for us to be looking at when we’re looking at these peptides. Now, I want to get into some of the brain peptides. This is the nootrophic frontier. C-Max and C-Lank, there is Russian pharmacology that’s done. C-Max and C-Lank represent an interesting case study in how different regulatory environments and research traditions Dr. Deb Muth 50:36create challenges in evaluating this evidence. Both peptides were developed in Russia, are approved for their specific indications and have substantial Russian language and literature supporting their use. However, the FDA approval in the United States is still not there. C-Max is a seven amino acid. It’s a synthetic analog. It is a fragment, particularly ACTH 4 through 10. It’s sometimes called the melanocortin effects because it involves the melanocortin receptors of the central nervous system. CMAX was developed by the Institute of Molecular Genetics of Russia Academy of Sciences and is approved in Russia for several indications, including acute stroke, transient ischemic attacks, cognitive disorders. It has Russian approval and is based on clinical trials primarily in Russia. Dr. Deb Muth 51:39It does help to increase brain-derived neurotrophic factor, BDNF, a protein critical for neuroplasticity, the brain’s ability to form new connections and adapt to the challenges. BDNF supports neuronal survival and promotes growth of these new neurons. C-Max also influences neurotransmitter systems, particularly dopamine and serotonin, and there is some research that suggests it affects on metabolism as well, and endogenous opioid peptides that involve pain reception and mood regulation. So it has some good potentials there. There is also C-Link, which is a hepatopeptide structurally similar to Tufts’ and an immune modulatory peptide. It was also developed in Russia and was approved for anxiety disorders as a neurotropic. Its effects involve anxiolytic effects, possibly through the GABAnergic system or the GABA system of the brain, and immune modulation. Dr. Deb Muth 52:44The Russian research is examined by C-Link for anxiety disorders. and finding reductions in anxiety without sedation. There is a dependency potential or cognitive impairment does not exist like it does with benzodiazepines with C-Link. So that is really good. And they do report attention and memory improvement using C-Link. There is a study that was done in neuroscience and behavioral psychology in 2018 that examined C-Linx effects and proposed that it exerts cytoprotective effects through BDNF pathways similar to C-Max. So both of these are Russian research-based They’re not wrong or fraudulent. It’s just that they are from Russia and we all have our concerns with Russia. However, that does not necessarily mean their research doesn’t hold quality. Dr. Deb Muth 53:49Neither peptide is approved by the FDA, and so you are using this off-label. The same rules apply for all of the other peptides that we’ve talked about that are produced off label. You want to do the same things that you would do with anything else. Good protein, omegas, B vitamins, acetylcarnitine, exercise, sleep, all of that still applies when we’re using these peptides. So I want to talk briefly about clinical decision and framework when we’re looking at this. First and foremost, we always want to go to FDA-approved peptides. Secondly, we would look at international approval with peptides that are established in other countries but lack FDA approval. And then preclinical evidence only or experimental peptides. These can be used, but they are not ethically recommended in the traditional medicine world. Dr. Deb Muth 54:50 If patients use them, we need to have appropriate counseling about the evidence surrounding them, the safety, and where to find them. how to find them and how to ask for these certificates of analysis. So I think it’s really good that we were exploring all these peptides and understanding what they are. There’s a lot of controversy out there. There’s a lot of concern out there. And what we can say with confidence is that peptides are powerful biological signaling molecules. Some peptide based medications, semi-glutide, triseptide, PT 141, Lupron that are all FDA approved. can dramatically improve outcomes in patients that are obviously selected for the correct ones. There are many other peptides that we address that are integrative and longevity space in the regenerative medicine. These peptides are all experimental. That does not automatically make them wrong. Dr. Deb Muth 55:50It just means that we need to be honest about what we’re doing with them and we need to be cautious with the patients so that they can make a decision to be part of an experimental study. in looking at how to use these peptides. So peptides are tools like any other tools. They work best in the hands of skilled people, and they are applied to appropriate situations, integrating into comprehensive approaches that address root causes. The most powerful peptide administered to a patient with untreated inflammation, hormonal chaos, nutritional deficiencies, and disorders of sleep will disappoint. The simplest evidence-based interventions apply. to a patient whose foundational physiology has been optimized. And this is the art of the science of peptide, right? If done right, respecting both the power of these molecules and the complexity of human beings that we are privileged to serve can make a difference in their lives.

Darshan H. Brahmbhatt, Podcast Editor of JACC: Advances, discusses a recently published original research paper on FGF-23, hsCRP, Cardiovascular Events, and the Benefit of Canagliflozin in the CANVAS Trial.

BUFFALO, NY — September 18, 2025 — A new #research paper was #published in Volume 17, Issue 8 of Aging-US on August 9, 2025, titled “The myokine FGF21 associates with enhanced survival in ALS and mitigates stress-induced cytotoxicity.” In this study, led by first author Abhishek Guha and corresponding author Peter H. King from the University of Alabama at Birmingham and the Birmingham Veterans Affairs Medical Center, researchers discovered that a hormone called FGF21, which is released by muscles, is elevated in people with amyotrophic lateral sclerosis (ALS) and may play a protective role. These findings are especially relevant because ALS is a fatal and currently incurable neurodegenerative disease. Amyotrophic lateral sclerosis is an age-related and progressive condition that affects the nerve cells responsible for muscle control. While some treatments can slow the disease, there is still a need to understand why ALS progresses at different rates in different individuals. “In a prior muscle miRNA sequencing investigation, we identified altered FGF pathways in ALS muscle, leading us to investigate FGF21.” The research team analyzed muscle biopsies, spinal cord tissue, and blood samples from ALS patients and found that FGF21 levels were significantly elevated. This increase was particularly evident in atrophied muscle fibers—those that had shrunk due to nerve loss—and in the surrounding tissue. Importantly, patients with higher plasma levels of FGF21 showed slower loss of function and longer survival, with some living more than six years after diagnosis. Using animal models and cultured cells, the researchers demonstrated that FGF21 levels rise even in the early, symptom-free stages of ALS. The hormone appeared to protect both muscle and motor neurons from stress-related damage. When added to stressed cells, FGF21 improved cell survival and reduced markers of cell death. In human muscle cells, FGF21 also supported the formation of new muscle fibers, a process known as myogenesis. Blood tests revealed that patients with higher levels of FGF21 not only experienced slower disease progression but also tended to have a higher body mass index (BMI), a factor previously associated with longer survival in ALS. This suggests that FGF21 may reflect a patient's ability to counteract ALS through natural protective mechanisms. It could also serve as a biomarker to monitor disease severity and potentially guide treatment decisions. The study also investigated how FGF21 communicates with cells. It found that the hormone's activity depends on a protein called β-Klotho, which was also altered in ALS-affected tissues. These changes were especially noticeable in motor neurons and muscle cells under stress, further highlighting FGF21's role in the body's response to damage. While the study does not show that FGF21 can be used as a treatment, it highlights the hormone as a promising target for future research, clinical trials, and strategies to slow ALS progression by leveraging the body's natural protective systems.

I cannot wait for you to hear this today! Whitney Capps and the incredible ladies of Point of Grace joined me at a Fresh Grounded Faith event in Springfield, Missouri, and let me tell you, there was something extra special about this day. Maybe it was because Whitney brought such raw honesty while in the middle of cancer treatments. Or maybe it was the sweet friendship and humility that Point of Grace radiated from the stage. Or maybe it was because someone in the audience tried to set KC up with her cousin, Brenda.

Get ready to laugh, learn, and maybe even tear up a little as we spill the beans LIVE from a Fresh Grounded Faith event in Bloomington, Illinois! My good friends Margaret Feinberg and Michael O'Brien joined me, and what an honest, hope-filled conversation we had in answering questions from the audience. We talked about the best way to handle stress and worry, how to know if God is calling you to step back in ministry, and what to do when grief knocks the wind out of you. Michael opens up about how his identity took a hit when he left the band, NewSong, and Margaret tells a hilarious (and slightly horrifying) story about showing up to an event without her pants. Yep, it happened! Today, we're answering your big questions, sharing our most embarrassing moments, and reminding you that God is present—even in the hard stuff.

This conversation is the opening segment of SurfingMASH's April discussion, in memory of Stephen A. Harrison, on drug development. In addition to co-hosts Jörn Schattenberg, Louise Campbell and Roger Green, panelists include hepatologists and key opinion leaders Sven Francque and Naim Alkhouri. This opening discussion focuses on exciting advances in one drug class (FGF-21s) and, more broadly, on exploring ways to treat cirrhosis. As Naim points out in his opening comment, these two issues— cirrhosis as a challenge and FGF-21s as a possible solution path —intersect in clear and exciting ways. He notes that the FGF-21 efruxifermin has been reported to have significant improvement in patients with cirrhosis, while the FGF-21 pegozafermin has shared positive results in a small cohort of patients. He also notes that a third FGF-21, efimosfermin alfa, has results in advanced non-cirrhotic MASH that suggest potential for similar efficacy in patients with cirrhosis, but this must be studied and confirmed in clinical trials. He mentions that resmetirom may also be showing signs of efficacy in some patients with cirrhosis. The entire package, he says, is a "game changer."Jörn notes that we are having parallel advances in treatment for advanced, non-cirrhotic patients. Sven concurs and comments that we are seeing effects that are not strictly related to metabolic disease. There is exceptional power that we can demonstrate one-level regression in sicker patients. The three agree that, at the same time, we are seeing cirrhosis trials that will lead to outcomes data; outcomes trials in non-cirrhotic medications may not be far away.Roger asks whether we are making progress in treating patients living with decompensated cirrhosis. Sven discusses what we are learning about treating portal hypertension, which is an important benefit unrelated to fibrosis regression. Simply improving portal hypertension will have an impact on endpoints. Naim points out that some ongoing trials include patients with cirrhosis, including survodutide and belapectin. Louise notes it will require "great P.R." to reverse some of the current perceptions about cirrhosis, but that this is "great." Naim states that even today, we have "a lot to offer" patients with portal hypertension or other symptoms of decompensation. As he concludes, he notes that this is underappreciated today. 

00:00:00 - Surf's Up: Season 6 Episode 5Host Roger Green briefly describes this episode's three sections and introduces Roundtable guests. The Roundtable panel shares groundbreakers. 00:10:39 - Roundtable: A Deep Dive Into Drug Development, Part OneThe opening portion of this month's roundtable centers around two issues: exciting data for FGF-21s and, more generally, treating patients with cirrhosis. Naim Alkhouri sets the tone in his opening comments, which start by focusing on the exciting SYMMETRY data from efruxifermin and then hones in on FGF-21s and resmetirom in cirrhosis. The rest of the conversation features Jörh Schattenberg, Sven Francque and Naim discussing therapies in development for compensated and decompensating cirrhosis.00;24:44 - Newsmaker: Naga Chalasani on Real-World Experience Prescribing ResmetiromNaga joins Roger to discuss the paper Early Experience with resmetirom to treat Metabolic Dysfunction-Associated Steatohepatitis With Fibrosis in a Real-World Setting from his group at Indiana University, which his group authored and Hepatology Communications recently posted. The paper, based on IU Health's experience with its first 113 resmetirom patients, shares the group's practical experience developing processes to work closely with the specialty pharmacies dispensing resmetirom and, finally, concludes that a more engaged patient management strategy might reduce drug discontinuation to a level comparable with clinical trials.  00:47:21 - Expert: Scott Friedman on Gene Therapy, Diversity of Stellate Cell Types, Other Basic Liver ScienceScott and Roger cover a range of basis science topics in a fast-moving 19-minute discussion. It starts with Scott discussing the increasing acceptance that gene therapy is an acceptable way to treat a range of liver diseases, many of which are orphan or ultra-orphan but, in fact, include potential gene therapies for non-cirrhotic MASH and MASH cirrhosis. He notes that in addition to classic gene therapy, which introduces protective gene variants into the systems of patients with the risky variants, gene therapy is now looking to introduce FGF-21 into patients through genetic modification. From there, the conversation covers CAR-T therapy, the increasing ability to identify many different types of stellate cells and the idea that the most effective therapy for eary fibrosis, advanced fibrosis and cirrhosis might require fundamentally different kinds of interventions. The two final elements are the idea that what we now call "MASH" may be several diseases with different etiologies with similar manifestations and a passionate call for all of us to support maintaining NIH funding in whatever ways we can.01:06:45 - Business ReportAs Roger copes with his laryngitis, AI voices deliver an abbreviated business report 

This week's expert, Hepatologist and Key Opinion Leader Mazen Noureddin, joins Roger to discuss major advances in drug development over the past year. He covers a range of different drug classes, focusing on stages of development and the range of options within each class. First, Mazen discusses a tremendously exciting group of FGF-21 agents, specifically mentioning Akero Therapeutics's efruxifermin, 89bio's pegozafermin, and Boston Pharmaceuticals's efimosfermin. He points to efruxifermin's 96-week results to suggest that FGF-21s might be appropriate for a wide range of patients, the idea that the drug's duration of effect may make the idea of “induction therapy” less appropriate, and the exciting early data on cirrhosis patients. He also mentions pegozafermin's publication of data in the New England Journal of Medicine and efimosfermin's promising data based on monthly dosing. Next, Mazen provides some detail on the various incretin agonist options, why hepatologists are particularly excited about combinations that include a glucagon agent, and what kinds of results we might expect in upcoming trials. Finally, Mazen discusses other promising compounds in later-stage development, including the pan-PPAR lanifibranor and the FASN inhibitor denifenstat. He notes ongoing work on new classes and combination therapies. 

00:00:00 - Surf's Up: Season 6 Episode 4 Surfing the MASH Tsunami concludes its coverage of the AASLD Emerging Trends Conference on MASLD, MetALD and ALD. This week, the panelists focus on pivotal messages that attendees took away from the conference and what messages they would like to share with listeners. Our newsmaker, Fatty Liver Alliance and CEO Mike Betel, discusses the lessons he has taken from being invited to a far wider swath of conferences this year and shares the messages he delivers to these new audiences. Finally, our expert, hepatology research and key opinion leader Mazen Noureddin, discusses recent advances in drug development, focusing on agents in Phase 3 trials.00:04:24 - IntroductionHost Roger Green briefly describes this episode's three sections and one key lesson from each.00:06:03 - Roundtable: Highlights from the AASLD Emerging Trends Conference, Part 4This is the concluding portion of our Emerging Trends Conference Roundtable. The group focuses on key lessons they have learned and messages they would like listeners to take from this conversation.  The pivotal idea is that SLD is a spectrum running from MASLD through MetALD to ALD. Researchers and treaters will all do best in developing and implementing therapies and guidelines with this thought in mind. Aleksander Krag stresses this idea and notes that, with several different classes of drugs demonstrating positive impact, it will be an exciting decade ahead as we learn how to apply these drugs along the spectrum. Jenn Jones and Alex Lalos note the importance of identifying MetALD, although Jenn noted that it does not seem wise to conduct trials solely with MetALD patients at this time.  00:22:04 - Newsmaker: Mike Betel on the Increased Visibility of Patient AdvocatesThis week's newsmaker, Mike Betel, has experienced a significant increase in the number of conferences at which he is invited to speak or appear on a panel. This discussion centers around the reasons Mike believes this is happening and the message(s) he delivers. To Mike, his most important contribution lies in the amount of information he sends back from each event, many of which surpass 30% download rates (and some even hit 50%). He discusses his value in diabetes, endocrinology and obesity meetings, where he brings a "liver" perspective and co-education opportunity to these events. The entire experience has taught him about the need not to stigmatize patients and reinforced his belief in the importance of tailoring care to patients' needs and personalities. 00:49:28 - Expert: Mazen Noureddin on the Exciting MASLD Drug Development EnvironmentHepatologist and Key Opinion Leader Mazen Noureddin joins Roger to discuss major advances in drug development over the past year. He covers a range of different drug classes, focusing on stages of development and the range of options within each class. Specifically, he discusses the FGF-21 agents, the range of patients for whom they might be appropriate, how efruxifermin's 96-week results may make the idea of "induction therapy" less appropriate,  and the exciting early data on cirrhosis patients. He provides some detail on the various incretin agonist options, why hepatologists are particularly excited about combinations that include a glucagon agent, and what kinds of results we might expect in upcoming trials. He goes on to discuss the pan-PPAR lanifibranor, the FASN inhibitor denifenstat, and notes ongoing work on new classes and combination therapies. In general, he paints, I think, not a rosy, but an extremely optimistic picture of what the future will be for patients who need to be treated for fatty liver. 01:09:38 - Business Report Roger discusses the next Roundtable and provides some details on SurfingMASH's coverage of the upcoming EASL Congress.

Surfing the MASH Tsunami continues its coverage of the AASLD Emerging Trends Conference on MASLD, MetALD and ALD. This week, the panelists focus on what studies on bariatric surgery and drugs in development can tell us about future treatment and explore some clinical trial questions. Guest Surfers include Professor Aleksander Krag of the University of Southern Denmark, the current Secretary-General of EALS, hepatologist Alexander Lalos of Robert Wood Johnson hospital, and Jenn Leigh Jones, founder of the Society for Sober Livers Survival, now part of the Fatty Liver Foundation. Aleksander Krag starts by discussing a presentation on what we can learn from bariatric surgery in terms of fibrosis reduction and why pharmacotherapies work (or not). He envisions a day where we have multiple treatment options and understanding how each works for specific types of patients, leading to robust, cost-effective, patient-specific treatment algorithms.  Alex Lalos describes how presentations on FGF-21s in advanced fibrosis and cirrhosis have whetted his appetite and Jenn Jones asks questions regarding ALD patient trial selection and assignment and clinical endpoints for cirrhosis trials. 

00:00:00 - Surf's Up: Season 6 Episode 3Surfing the MASH Tsunami continues its coverage of the AASLD Emerging Trends Conference on MASLD, MetALD and ALD. This week, the panelists focus on what studies on bariatric surgery and drugs in development can tell us about future treatment and explore some clinical trial questions. Our newsmaker, HistoIndex Director of Clinical Development Yukti Choudhury, introduces us to FibroSIGHT, which provides clinicians with highly precise biopsy analysis. Finally, our expert, Global Liver Institute Vice President, Liver Programs Jeff McIntyre, discusses the implications of recent US government job cuts on future MASH treatment options and patient care.00:04:35 - IntroductionHost Roger Green briefly describes this episode's three sections and one key lesson from each.00:05:45 - Roundtable: Highlights from the AASLD Emerging Trends Conference, Part 3This portion of our Emerging Trends Conference Roundtable looks at how therapy might evolve over time. Aleksander Krag starts by discussing a presentation on what we can learn from bariatric surgery in terms of fibrosis reduction and why pharmacotherapies work (or not). He envisions a day where we have multiple treatment options and understanding how each works for specific types of patients, leading to robust, cost-effective, patient-specific treatment algorithms.  Alex Lalos describes how presentations on FGF-21s in advanced fibrosis and cirrhosis have whetted his appetite and Jenn Jones asks questions regarding ALD patient trial selection and assignment and clinical endpoints for cirrhosis trials. 00:16:55 - Newsmakers: FibroSIGHT Brings Clinical Trial Analytics to Clinical Practice Use of BiopsyYukti Choudhury, Director of Clinical Development at HistoIndex, joins Roger Green to discuss FibroSIGHT, a new HistoIndex service that allows clinicians to use HistoIndex's Second Harmonic Generation (SHG) technology to determine specific CRN fibrosis level for patients with inconclusive NIT results.  Yukti states that demand for this technique could equal 163,000 cases this year and rising to one million by 2028. She provides practical cues on ordering the test and its reimbursement. Roger shares his long-standing respect for SHG and the clarity it produces. He notes the economic benefit of determining whether a patient has F2 fibrosis, which is indicated for pharmacotherapy, vs.F1, which is not indicated. He sees clear benefit, but expresses concern that any option requiring more biopsies will reduce the number of patients treated.00:41:49 - Patient Advocate and Policy Expert Jeff McIntyre Discusses the Implications of FA/NIH Job Cuts on MASLD Patient CareGlobal Liver Institute Vice President, Liver Programs Jeff McIntyre joins Roger to discuss the April 1 job reductions at the FDA, explore implications for the entire MASLD community, and to ask what patients can and should do. Jeff and Roger note that the job changes will create significant uncertainty and probably reduce the government's ability to respond to future health crises. Jeff notes former FDA Commissioner Rob Califf's comment that the FDA as we know it "is dead," and that we have little idea what the future holds. According to Jeff, patients need to become even more vigilant self-advocates and also seek the guidance and support they need from patient advocacies. Finally, the conversation turns to discuss FibroSIGHT. Jeff describes FibroSIGHT as "exactly where we should be and should not be at the same time," a technology that takes a large step forward in understanding and patient support, but one that ties us to biopsy as a standard for clinical care. Jeff and Roger agree this issue will play out over the coming years. 01:09:18 - Business ReportRoger thanks listeners quoting a letter from one of them, and describes the next round of episodes. 

In this episode, Naim Alkhouri, Mike Betel, Michelle Long and Jeff McIntyre join Jörn Schattenberg and Roger Green to look back at The Liver Meeting 2024. This conversation reviews the late-breaker presentation on efimosermin, a q4w FGF-21 agent and the "FDA Corner" session. Jörn begins the discussion by highlighting a paper from the later breaker session on efimosfermin alfa, an FGF-21 agent dosed q4w. He notes that after only six doses (24 weeks), efimosfermin alfa demonstrated significant increases in fibrosis regression and lowering NAS score. To Jörn, this result, coupled with others on efruxifermin and pegozafermin, suggest that FGF-21s are likely to play a significant role in MASH therapy once approved. After Roger and Mike note their enthusiasm about the drug class and this study, Jörn mentions a study with 96-week efruxifermin that data demonstrates prolonged efficacy. As he points out, this matters because while studies of an earlier FGF-21 candidate suggested that antibodies might develop in FGF-21 therapy, that does not appear to be an issue here. Mike asks the group why they feel placebo performs so well in clinical trials. Jörn suggests that working with a compassionate clinical care team in dealing with the patient leads to better performance on diet and exercise and, as a result, increased placebo response to what we might find in general community practice.Michelle praises the FDA Corner session, particularly the agency's transparency and willingness to engage industry and academia in finding paths to move away from biopsy. She also notes some of the practical challenges inherent of moving away from biopsy using data from earlier trials with an outmoded histology reader setup. She is optimistic about the scientific community coming together to address these issues. Jeff praises the agency for an "amazing" session. 

00:00:00 – Surf's Up: Season 5 Episode 26 - Last month, close to 8,000 hepatology stakeholders convened in San Diego for The Liver Meeting 2024. Hepatology Key Opinion Leader Naim Alkhouri, Novo Nordisk International Vice President for Medicines Michelle Long, and patient advocates Jeff McIntyre from the Global Liver Institute and Michael Betel from the Fatty Liver Alliance join Jörn Schattenberg and Roger Green to discuss highlights. 00:03:23 - Introduction and Groundbreaker - Highlights include recent travel, cultural events, and the Third Annual Primary Care Summit from the Fatty Liver Alliance.00:11:35 - Describing TLM2024 - Participants shared a word or short phrase they felt best captured their feelings about TLM2024. 00:14:51 - The ESSENCE Trial - Naim starts the session by describing ESSENCE, a Phase 3 trial of semaglutide in non-cirrhotic MASH patients, which he describes as "the most exciting news of the meeting." Panelists describe the benefits of this trial from a variety of perspectives. 00.22.49 - A Challenge to Trial Recruitment? - Roger asks the group whether the presence of two approved MASH medications that do not require biopsy will make recruiting clinical trials that require them more challenging. The group doubts this will not add a significant new challenge to already-challenging trial recruitment. 00:29:22 - Other keys in drug development - Naim begins a discussion of two topics: the value of synergy between resmetirom and the GLP-1 agonist, and the importance of different genetic polymorphisms in predicting the impact of drugs on specific patients. Michelle mentions a recent paper in Nature identifying distinct clusters of patients based on how their SLDs progress over time. Roger identifies two particular challenges in this area, one posed by Lean MASH and the other specific to Hispanics in the US. 00:34:42 - FGF 21s - Jörn highlights a paper from the later breaker session on efimosfermin alfa, an FGF-21 dosed q4w. Roger and Mike comment. To Jörn, this and other studies demonstrate the place FGF-21s are likely to have in MASH therapy.00:40:29 - FDA Corner and the Role of Surrogates - Michelle praises the FDA Corner session, particularly the agency's transparency and willingness to engage industry and academia in finding paths to move away from biopsy. She is optimistic about the scientific community coming together to address these issues. Jeff notes the pivotal role he believes patients must play in this process. 00:48:33 - Patient Insights - Mike describes a poster he presented (and was lead co-author), titled Patient Voice in MASH Initiatives:  Foundational Principles for the Conduct of Patient-Centric MASH Research. He lists the groups participating in this broad effort and the foundational principles that emerged. Michelle and Jörn share their thoughts on which principles have the greatest impact on them in clinical research. Jeff praises a panel that Mike co-chaired on Lifestyle Management of MASLD and MASH. He praises the breadth and quality of speakers and topics. He also comments on the large number of providers and industry executives who attended this patient-centered session. Roger notes a similar distribution of attendees at the Health Livers, Healthy Lives session on building momentum for prevention. 00:58:36 - Wrapping Up - Roger comments on the breadth of modes of action that have produced successful Phase 2/3 trial results. He notes that we may have 4-5 different modes of action available five years from now. In the rest of the session, panelists describe what they believe will be different and exciting at TLM2025.01:06:01 - Question of the WeekListeners and readers, What do you consider the most essential paper or theme of TLM2024??01:06:38 - Business ReportChanges coming in 2025 with SurfingMASH v2.0

PFAs on an FGF, deer hunting, and our take on RFK's appointment to the cabinet.

David Happel is President and CEO of Sagimet Biosciences, a company developing drugs to treat metabolic diseases by targeting the underlying cause of fat accumulation in the liver. The drug denifanstat limits the activity of fatty acid synthase (FASN), an enzyme that regulates fat accumulation. This approach is a fat inhibitor, not a fat burner, the focus of other MASH drugs.  David explains, "Sagimet was founded back in 2007 as a private company with a group of medicinal chemists that had a particular target in mind, and this particular target was called fatty acid synthase, or FASN. FASN is a rather ubiquitous enzyme throughout the body that functions as a regulating enzyme in many organs. When FASN becomes overactive or overexpressed, it sort of throws things out of balance and, in particular, certain cardiometabolic diseases, such as MASH and in the liver. So, this group of chemists, in order to resolve this overactivity, developed a portfolio of FASN inhibitors, led by our lead program denifanstat, that seek to target the underlying cause of MASH and, therefore, really work to limit the activity of FASN, try to normalize it essentially is what we do." "For us and this particular molecule, it offers a differentiated approach to treating the disease for us and this particular molecule. Our molecule, denifanstat, is the only FASN inhibitor. It's the only fat inhibitor in development for MASH, making it rather unique. All the rest of the molecules or fat burners, fat oxidizers, and fat mobilizers include GLPs, FGF, and THR-beta. They all function by trying to burn fat peripherally and in the liver to a degree. They rely on that fat-burning mechanism to translate into reductions, inflammation, and fibrosis, which is important to treating MASH, but they've had varying degrees of success. Our molecule targets each pathway independently: fat, inflammation, and fibrosis, and has had a rather pronounced treatment effect as a result."  #SagimetBiosciences #MASH #FattyLiverDisease #FASN #FASNInhibitor #Fibrosis #Obesity #NASH #GLP1Agonists sagimet.com Download the transcript here

From wound healing to cell growth to bone formation, fibroblast growth factors (FGF) and fibroblast growth factor receptors (FGFR) are responsible for a diverse range of biological processes. This episode begins with the basics: the functions of FGFs and FGFRs. We will then move on to an indepth dive into the structure of FGFRs and how they work with FGFs to initiate the desired cellular response. Finally, we will end the episode by exploring the three main pathways used by FGFs and their corresponding receptors.  FGFR Model: https://images.app.goo.gl/FaZjvuh5H1QnTgfa8

This conversation contains the first half of Roger Green's interview with Global Liver Institute Vice President, Liver Programs Jeff McIntyre, during which the two discuss what Jeff considered the key strategic takeaways for GLI from the various EASL Congress presentations, abstracts and discussions. Jeff focuses on the "overriding sense of optimism" coming from the multiple pieces of positive drug data. He cites the data on Boehringer Ingelheim's survodutide, the follow-up work on Madrigal's resmetirom, an anticipated presentation on semaglutide at the AASLD in November, and strong FGF-21 results as proof that we are beginning to develop multiple robust, safe and effective modes of action for drugs to treat (at least pre-cirrhotic) MASH. His second positive point is that due to the drug trials and nomenclature change, GLI and other advocates are starting to have "more enlightened discussions" about MASLD in the context of the whole patient and related metabolic conditions. As a result, he comes to the third point, which is that multiple modes of action will teach us why what works in one patient might not in another and, ultimately, reshape clinical trials so that the target might not be fibrosis (or at least not only fibrosis), but instead exactly how each drug works. Jeff envisions this line of inquiry as a step down the path away from requiring biopsy. 

Mazen Noureddin and Naim Alkhouri join Jörn Schattenberg and Roger Green to focus on the role FGF-21s will play in long-term advanced fibrosis treatment: induction or long-term therapy...or might we even think of the class as being able to produce a "MASH cure?" Responding to Naim's comment closing the previous discussion, Mazen questions why we regard FGF-21 agents as induction therapies given that it appears to be as well tolerated as the oral agents and maintains such efficacy over time. In fact, he adds, its sustained efficacy might make it possible for livers to eliminate fibrosis and return to their "normal" state, almost like a "cure." Jörn adds a comment about pegozafermin, another FGF-21 in development. Jörn notes that this agent is a pegylated molecule, which makes it different from efruxifermin. He notes that NITs show sustained enzyme response at 48 weeks. Mazen reiterates his optimism about the FGF-21 class and reminds us that there is a third FGF-21 in development. Roger raises Michael Charlton's question (Season 5 Episode 11) whether an induction therapy strategy for FGF-21s might not work if removing the drug allows the MAS activity to return. On the other hand, he notes, it might take years for fibrosis to return. Mazen agrees that many unanswered questions exist, but reiterates his belief in long-term therapeutic value.  

In this conversation from July 2023, Stephen Harrison, Jörn Schattenberg and Roger Green discuss the implications of presentations on the FGF-21 agent efruxifermin and the dual GLP/glucagon agonists pemvidutide and efinopegdutide. Here is the description Roger wrote for the original conversation:In this session, conversation shifts from resmetirom to Mazen Noureddin's "NASH Monopoly" game and focuses on the value of FGF-21s and glucagon agents. Stephen posits two comments about GLP-1s. First, there is now adequate data suggesting that GLP-1s will not melt away all liver fat and as a result lead to dramatic fibrosis regression. Second, we know from a small sub-cohort of patients in Akero's SYMMETRY trial that patients already on fairly low doses of GLP-1s saw what Stephen describes as an 'incredible' and incremental benefit for the FGF-21 agent, efruxifermin. The group notes that while glucagon dual and treble agents are likely to produce dramatically more robust results in weight loss and liver defatting than GLP-1s alone, they still seem unlikely to 'usurp the need for other types of agents.' From here discussion considers the FGF-21 class. Stephen notes that two drugs, efruxifermin and pegozafermin, have demonstrated significant efficacy against fibrosis. As the conversation concludes, the panelists agree that earlier, more aggressive screening to arrest cirrhosis will become pivotal and will not occur until the right drug becomes available. 

Naim Alkhouri and Mazen Noureddin join Jörn Schattenberg and Roger Green to discuss issues regarding incretin agonists and results from the efruxiermin late-breaker at the EASL Congress 2024. Naim shares his general excitement about glucagon agents in general. He mentions that the efinopegdutide study included a semaglutide cell, which showed further reduction in liver fat vs. the GLP-1 agent. Jörn comments on the high level of tolerability in the survodutide trials. Mazen shares his high hopes for GLP/glucagons and the triple agents. He goes back to review the survodutide data from the NEJM article. Mazen shares the late-breaker data that Vlad Ratziu presented on behalf of Stephen. This is a 96-week, triple biopsy study showing dramatic, sustained fibrosis improvement with a 30% delta for one level and a 21% delta for two levels. Jörn notes that the triple biopsies are demonstrate the durability of the agent against fibrosis. Roger notes this is particularly encouraging because of the previous pegbelfermin data showing loss of efficacy and tachyphylaxis. Naim concurs and adds that if the two-stage drop in fibrosis can be sustained, this would be a "big deal for the field" that might lead prescribers to think about FGF-21 as indication therapy with a "more tolerated" oral later on.   

00:00:00 Surf's Up, Season 5 Episode 20Naim Alkhouri and Mazen Noureddin join co-hosts Jörn Schattenberg and Roger Green to discuss major drug development stories from the EASL Congress 2024. They pay tribute to Stephen Harrison and proceed to groundbreakers.00:08:16 - Presentations on ResmetiromMazen shares a paper he presented looking at resmetirom dose-response. The 100mg dose performed better than the 80mg dose. Jörn notes that the most important element of the study might be the demonstrated 36-month effect.  00:14:19- Implications of Different Analytical Modes Naim compares different modes of analysis. Intent to Treat, which treats all non-completers as failures, will produce lower rates of response than a "completer" or "modified Intent to Treat" analysis, which either eliminates non-completers or assigns them placebo-level response. 00:16:12 - The "Twin-Cretins"Jörn coined  the name "Twin-cretins" for agents with GLP-1 agonism plus another incretin effect. Tirzepatide is a GLP/GIP while survodutide, pemvuditide, and efinopegdutide, are GLP/glucagons. Naim reviews the tirzepatide late-breaker presentation, which showed high rates of MASH resolution, but, as a completer analysis, might not have proven whether a GLP/GIP can achieve significant fibrosis regression.  Naim notes that Stephen doubted strongly this was possible, but that bariatric surgery's effect creates a paradox. Mazen concurs, and states he is more confident in the GLP/glucagon agents. Jörn agrees. 00:23:09 - Implications of widespread GLP useRoger asks how widespread prior patient use of incretins will affect prescribing. Naim states that many of his Rezdiffra MASH patients have been on GLP-1 already.  He describes a key difference between the three GLP/glucagon agents in development. 00:24:20 - The previous GLP/glucagon studiesNaim expresses his excitement about glucagon agents in general. He mentions that the efinopegdutide study included a semaglutide cell, which showed a further reduction in liver fat compared to the GLP-1 agent. 00:26:44 - Safety of survodutide in cirrhosisJörn comments on the high level of tolerability in the survodutide trials. Mazen shares his high hopes for GLP/glucagons and the triple agents. He reviews survodutide data from the NEJM article.  00:29:41 - FGF-21s, starting with efrux data Focus shifts to FGF-21s. Mazen shares data from the efruxifermin late-breaker, a 96-week, triple biopsy study showing dramatic, sustained one- and two-level fibrosis improvement. Jörn notes the design demonstrates durability, which Roger finds particularly encouraging given the pegbelfermin experience. Naim  adds that a sustainable two-stage drop in fibrosis might position FGF-21 as induction therapy before long-term oral maintenance.   00:35:28 - Is a drug-based MASH "cure" possible?

The most enthralling conversation I've ever had with anyone on cancer. It's with Charlie Swanton who is a senior group leader at the Francis Crick Institute, the Royal Society Napier Professor in Cancer and medical oncologist at University College London, co-director of Cancer Research UK.Video snippet from our conversation. Full videos of all Ground Truths podcasts can be seen on YouTube here. The audios are also available on Apple and Spotify.Transcript with audio links and many external linksEric Topol (00:07):Well, hello, this is Eric Topol with Ground Truths, and I am really fortunate today to connect us with Charlie Swanton, who is if not the most prolific researcher in the space of oncology and medicine, and he's right up there. Charlie is a physician scientist who is an oncologist at Francis Crick and he heads up the lung cancer area there. So Charlie, welcome.Charles Swanton (00:40):Thank you, Eric. Nice to meet you.Learning from a FailureEric Topol (00:43):Well, it really is a treat because I've been reading your papers and they're diverse. They're not just on cancer. Could be connecting things like air pollution, it could be Covid, it could be AI, all sorts of things. And it's really quite extraordinary. So I thought I'd start out with a really interesting short paper you wrote towards the end of last year to give a sense about you. It was called Turning a failing PhD around. And that's good because it's kind of historical anchoring. Before we get into some of your latest contributions, maybe can you tell us about that story about what you went through with your PhD?Charles Swanton (01:26):Yeah, well thank you, Eric. I got into research quite early. I did what you in the US would call the MD PhD program. So in my twenties I started a PhD in a molecular biology lab at what was then called the Imperial Cancer Research Fund, which was the sort of the mecca for DNA tumor viruses, if you like. It was really the place to go if you wanted to study how DNA tumor viruses worked, and many of the components of the cell cycle were discovered there in the 80s and 90s. Of course, Paul Nurse was the director of the institute at the time who discovered cdc2, the archetypal regulator of the cell cycle that led to his Nobel Prize. So it was a very exciting place to work, but my PhD wasn't going terribly well. And sort of 18, 19 months into my PhD, I was summoned for my midterm reports and it was not materializing rapidly enough.(02:25):And I sat down with my graduate student supervisors who were very kind, very generous, but basically said, Charlie, this isn't going well, is it? You've got two choices. You can either go back to medical school or change PhD projects. What do you want to do? And I said, well, I can't go back to medical school because I'm now two years behind. So instead I think what I'll do is I'll change PhD projects. And they asked me what I'd like to do. And back then we didn't know how p21, the CDK inhibitor bound to cyclin D, and I said, that's what I want to understand how these proteins interact biochemically. And they said, how are you going to do that? And I said, I'm not too sure, but maybe we'll try yeast two-hybrid screen and a mutagenesis screen. And that didn't work either. And in the end, something remarkable happened.(03:14):My PhD boss, Nic Jones, who's a great guy, still is, retired though now, but a phenomenal scientist. He put me in touch with a colleague who actually works next door to me now at the Francis Crick Institute called Neil McDonald, a structural biologist. And they had just solved, well, the community had just solved the structure. Pavletich just solved the structure of cyclin A CDK2. And so, Neil could show me this beautiful image of the crystal structure in 3D of cyclin A, and we could mirror cyclin D onto it and find the surface residue. So I spent the whole of my summer holiday mutating every surface exposed acid on cyclin D to an alanine until I found one that failed to interact with p21, but could still bind the CDK. And that little breakthrough, very little breakthrough led to this discovery that I had where the viral cyclins encoded by Kaposi sarcoma herpes virus, very similar to cyclin D, except in this one region that I had found interactive with a CDK inhibitor protein p21.(04:17):And so, I asked my boss, what do you think about the possibility this cyclin could have evolved from cyclin D but now mutated its surface residues in a specific area so that it can't be inhibited by any of the control proteins in the mammalian cell cycle? He said, it's a great idea, Charlie, give it a shot. And it worked. And then six months later, we got a Nature paper. And that for me was like, I cannot tell you how exciting, not the Nature paper so much as the discovery that you were the first person in the world to ever see this beautiful aspect of evolutionary biology at play and how this cyclin had adapted to just drive the cell cycle without being inhibited. For me, just, I mean, it was like a dream come true, and I never experienced anything like it before, and I guess it's sizes the equivalent to me of a class A drug. You get such a buzz out of it and over the years you sort of long for that to happen again. And occasionally it does, and it's just a wonderful profession.Eric Topol (05:20):Well, I thought that it was such a great story because here you were about to fail. I mean literally fail, and you really were able to turn it around and it should give hope to everybody working in science out there that they could just be right around the corner from a significant discovery.Charles Swanton (05:36):I think what doesn't break you makes you stronger. You just got to plow on if you love it enough, you'll find a way forward eventually, I hope.Tracing the Evolution of Cancer (TRACERx)Eric Topol (05:44):Yeah, no question about that. Now, some of your recent contributions, I mean, it's just amazing to me. I just try to keep up with the literature just keeping up with you.Charles Swanton (05:58):Eric, it's sweet of you. The first thing to say is it's not just me. This is a big community of lung cancer researchers we have thanks to Cancer Research UK funded around TRACERx and the lung cancer center. Every one of my papers has three corresponding authors, multiple co-first authors that all contribute in this multidisciplinary team to the sort of series of small incremental discoveries. And it's absolutely not just me. I've got an amazing team of scientists who I work with and learn from, so it's sweet to give me the credit.Eric Topol (06:30):I think what you're saying is really important. It is a team, but I think what I see through it all is that you're an inspiration to the team. You pull people together from all over the world on these projects and it's pretty extraordinary, so that's what I would say.Charles Swanton (06:49):The lung community, Eric, the lung cancer community is just unbelievably conducive to collaboration and advancing understanding of the disease together. It's just such a privilege to be working in this field. I know that sounds terribly corny, but it is true. I don't think I recall a single email to anybody where I've asked if we can collaborate where they've said, no, everybody wants to help. Everybody wants to work together on this challenge. It's just such an amazing field to be working in.Eric Topol (07:19):Yeah. Well I was going to ask you about that. And of course you could have restricted your efforts or focused on different cancers. What made you land in lung cancer? Not that that's only part of what you're working on, but that being the main thing, what drew you to that area?Charles Swanton (07:39):So I think the answer to your question is back in 2008 when I was looking for a niche, back then it was lung cancer was just on the brink of becoming an exciting place to work, but back then nobody wanted to work in that field. So there was a chair position in thoracic oncology and precision medicine open at University College London Hospital that had been open, as I understand it for two years. And I don't think anybody had applied. So I applied and because I was the only one, I got it and the rest is history.(08:16):And of course that was right at the time when the IPASS draft from Tony Mok was published and was just a bit after when the poster child of EGFR TKIs and EGFR mutant lung cancer had finally proven that if you segregate that population of patients with EGFR activating mutation, they do incredibly well on an EGFR inhibitor. And that was sort of the solid tumor poster child along with Herceptin of precision medicine, I think. And you saw the data at ASCO this week of Lorlatinib in re-arranged lung cancer. Patients are living way beyond five years now, and people are actually talking about this disease being more like CML. I mean, it's extraordinary the progress that's been made in the last two decades in my short career.Eric Topol (09:02):Actually, I do want to have you put that in perspective because it's really important what you just mentioned. I was going to ask you about this ASCO study with the AKT subgroup. So the cancer landscape of the lung has changed so much from what used to be a disease of cigarette smoking to now one of, I guess adenocarcinoma, non-small cell carcinoma, not related to cigarettes. We're going to talk about air pollution in a minute. This group that had, as you say, 60 month, five year plus survival versus what the standard therapy was a year plus is so extraordinary. But is that just a small subgroup within small cell lung cancer?Charles Swanton (09:48):Yes, it is, unfortunately. It's just a small subgroup. In our practice, probably less than 1% of all presentations often in never smokers, often in female, never smokers. So it is still in the UK at least a minority subset of adenocarcinomas, but it's still, as you rightly say, a minority of patients that we can make a big difference to with a drug that's pretty well tolerated, crosses the blood-brain barrier and prevents central nervous system relapse and progression. It really is an extraordinary breakthrough, I think. But that said, we're also seeing advances in smoking associated lung cancer with a high mutational burden with checkpoint inhibitor therapy, particularly in the neoadjuvant setting now prior to surgery. That's really, really impressive indeed. And adjuvant checkpoint inhibitor therapies as well as in the metastatic setting are absolutely improving survival times and outcomes now in a way that we couldn't have dreamt of 15 years ago. We've got much more than just platinum-based chemo is basically the bottom line now.Revving Up ImmunotherapyEric Topol (10:56):Right, right. Well that actually gets a natural question about immunotherapy also is one of the moving parts actually just amazing to me how that's really, it's almost like we're just scratching the surface of immunotherapy now with checkpoint inhibitors because the more we get the immune system revved up, the more we're seeing results, whether it's with vaccines or CAR-T, I mean it seems like we're just at the early stages of getting the immune system where it needs to be to tackle the cancer. What's your thought about that?Charles Swanton (11:32):I think you're absolutely right. We are, we're at the beginning of a very long journey thanks to Jim Allison and Honjo. We've got CTLA4 and PD-1/PDL-1 axis to target that's made a dramatic difference across multiple solid tumor types including melanoma and lung cancer. But undoubtedly, there are other targets we've seen LAG-3 and melanoma and then we're seeing new ways, as you rightly put it to mobilize the immune system to target cancers. And that can be done through vaccine based approaches where you stimulate the immune system against the patient's specific mutations in their cancer or adoptive T-cell therapies where you take the T-cells out of the tumor, you prime them against the mutations found in the tumor, you expand them and then give them back to the patient. And colleagues in the US, Steve Rosenberg and John Haanen in the Netherlands have done a remarkable job there in the context of melanoma, we're not a million miles away from European approvals and academic initiated manufacturing of T-cells for patients in national health systems like in the Netherlands.(12:50):John Haanen's work is remarkable in that regard. And then there are really spectacular ways of altering T-cells to be able to either migrate to the tumor or to target specific tumor antigens. You mentioned CAR-T cell therapies in the context of acute leukemia, really extraordinary developments there. And myeloma and diffuse large B-cell lymphoma as well as even in solid tumors are showing efficacy. And I really am very excited about the future of what we call biological therapies, be it vaccines, an antibody drug conjugates and T-cell therapies. I think cancer is a constantly adapting evolutionary force to be reckoned with what better system to combat it than our evolving immune system. It strikes me as being a future solution to many of these refractory cancers we still find difficult to treat.Eric Topol (13:48):Yeah, your point is an interesting parallel how the SARS-CoV-2 virus is constantly mutating and becoming more evasive as is the tumor in a person and the fact that we can try to amp up the immune system with these various means that you just were reviewing. You mentioned the other category that's very hot right now, which is the antibody drug conjugates. Could you explain a bit about how they work and why you think this is an important part of the future for cancer?Antibody-Drug ConjugatesCharles Swanton (14:26):That's a great question. So one of the challenges with chemotherapy, as you know, is the normal tissue toxicity. So for instance, neutropenia, hair loss, bowel dysfunction, diarrhea, epithelial damage, essentially as you know, cytotoxics affect rapidly dividing tissues, so bone marrow, epithelial tissues. And because until relatively recently we had no way of targeting chemotherapy patients experienced side effects associated with them. So over the last decade or so, pioneers in this field have brought together this idea of biological therapies linked with chemotherapy through a biological linker. And so one poster chart of that would be the drug T-DXd, which is essentially Herceptin linked to a chemotherapy drug. And this is just the most extraordinary drug that obviously binds the HER2 receptor, but brings the chemotherapy and proximity of the tumor. The idea being the more drug you can get into the tumor and the less you're releasing into normal tissue, the more on tumor cytotoxicity you'll have and the less off tumor on target normal tissue side effects you'll have. And to a large extent, that's being shown to be the case. That doesn't mean they're completely toxicity free, they're not. And one of the side effects associated with these drugs is pneumonitis.(16:03):But that said, the efficacy is simply extraordinary. And for example, we're having to rewrite the rule books if you like, I think. I mean I'm not a breast cancer physician, I used to be a long time ago, but back in the past in the early 2000s, there was HER2 positive breast cancer and that's it. Now they're talking about HER2 low, HER2 ultra-low, all of which seem to in their own way be sensitive to T-DXd, albeit to a lower extent than HER2 positive disease. But the point is that there doesn't seem to be HER2 completely zero tumor group in breast cancer. And even the HER2-0 seem to benefit from T-DXd to an extent. And the question is why? And I think what people are thinking now is it's a combination of very low cell service expression of HER2 that's undetectable by conventional methods like immunohistochemistry, but also something exquisitely specific about the way in which HER2 is mobilized on the membrane and taken back into the cell. That seems to be specific to the breast cancer cell but not normal tissue. So in other words, the antibody drug conjugate binds the tumor cell, it's thought the whole receptor's internalized into the endosome, and that's where the toxicity then happens. And it's something to do with the endosomal trafficking with the low level expression and internalization of the receptor. That may well be the reason why these HER2 low tumors are so sensitive to this beautiful technology.Eric Topol (17:38):Now I mean it is an amazing technology in all these years where we just were basically indiscriminately trying to kill cells and hoping that the cancer would succumb. And now you're finding whether you want to call it a carry or vector or Trojan horse, whatever you want to call it, but do you see that analogy of the HER2 receptor that's going to be seen across the board in other cancers?Charles Swanton (18:02):That's the big question, Eric. I think, and have we just lucked out with T-DXd, will we find other T-DXd like ADCs targeting other proteins? I mean there are a lot of ADCs being developed against a lot of different cell surface proteins, and I think the jury's still out. I'm confident we will, but we have to bear in mind that biology is a fickle friend and there may be something here related to the internalization of the receptor in breast cancer that makes this disease so exquisitely sensitive. So I think we just don't know yet. I'm reasonably confident that we will find other targets that are as profoundly sensitive as HER2 positive breast cancer, but time will tell.Cancer, A Systemic DiseaseEric Topol (18:49):Right. Now along these lines, well the recent paper that you had in Cell, called embracing cancer complexity, which we've talking about a bit, in fact it's kind of those two words go together awfully well, but hallmarks of systemic disease, this was a masterful review, as you say with the team that you led. But can you tell us about what's your main perspective about this systemic disease? I mean obviously there's been the cancer is like cardiovascular and cancers like this or that, but here you really brought it together with systemic illness. What can you say about that?Charles Swanton (19:42):Well, thanks for the question first of all, Eric. So a lot of this comes from some of my medical experience of treating cancer and thinking to myself over the years, molecular biology has had a major footprint on advances in treating the disease undoubtedly. But there are still aspects of medicine where molecular biology has had very little impact, and often that is in areas of suffering in patients with advanced disease and cancer related to things like cancer cachexia, thrombophilia. What is the reason why patients die blood clots? What is the reason patients die of cancer at all? Even a simple question like that, we don't always know the answer to, on death certificates, we write metastatic disease as a cause of cancer death, but we have patients who die with often limited disease burden and no obvious proximal cause of death sometimes. And that's very perplexing, and we need to understand that process better.(20:41):And we need to understand aspects like cancer pain, for example, circadian rhythms affect biological sensitivity of cancer cells to drugs and what have you. Thinking about cancer rather than just sort of a single group of chaotically proliferating cells to a vision of cancer interacting both locally within a microenvironment but more distantly across organs and how organs communicate with the cancer through neuronal networks, for example, I think is going to be the next big challenge by setting the field over the next decade or two. And I think then thinking about more broadly what I mean by embracing complexity, I think some of that relates to the limitations of the model systems we use, trying to understand inter-organ crosstalk, some of the things you cover in your beautiful Twitter reviews. (←Ground Truths link) I remember recently you highlighted four publications that looked at central nervous system, immune cell crosstalk or central nervous system microbiome crosstalk. It's this sort of long range interaction between organs, between the central nervous system and the immune system and the cancer that I'm hugely interested in because I really think there are vital clues there that will unlock new targets that will enable us to control cancers more effectively if we just understood these complex networks better and had more sophisticated animal model systems to be able to interpret these interactions.Eric Topol (22:11):No, it's so important what you're bringing out, the mysteries that still we have to deal with cancer, why patients have all these issues or dying without really knowing what's happened no less, as you say, these new connects that are being discovered at a remarkable pace, as you mentioned, that ground truths. And also, for example, when I spoke with Michelle Monje, she's amazing on the cancer, where hijacking the brain cells and just pretty extraordinary things. Now that gets me to another line of work of yours. I mean there are many, but the issue of evolution of the tumor, and if you could put that in context, a hot area that's helping us elucidate these mechanisms is known as spatial omics or spatial biology. This whole idea of being able to get the spatial temporal progression through single cell sequencing and single cell nuclei, all the single cell omics. So if you could kind of take us through what have we learned with this technique and spatial omics that now has changed or illuminated our understanding of how cancer evolves?Charles Swanton (23:37):Yeah, great question. Well, I mean I think it helps us sort of rewind a bit and think about evolution in general. Genetic selection brought about by diverse environments and environmental pressures that force evolution, genetic evolution, and speciation down certain evolutionary roots. And I think one can think about cancers in a similar way. They start from a single cell and we can trace the evolutionary paths of cancers by single cell analysis as well as bulk sequencing of spatially separated tumor regions to be able to reconstruct their subclones. And that's taught us to some extent, what are the early events in tumor evolution? What are the biological mechanisms driving branched evolution? How does genome instability begin in tumors? And we found through TRACERx work, whole genome doubling is a major route through to driving chromosome instability along with mutagenic enzymes like APOBEC that drive both mutations and chromosomal instability.(24:44):And then that leads to a sort of adaptive radiation in a sense, not dissimilar to I guess the Cambrian explosion of evolutionary opportunity upon which natural selection can act. And that's when you start to see the hallmarks of immune evasion like loss of HLA, the immune recognition molecules that bind the neoantigens or even loss of the neoantigens altogether or mutation of beta 2 microglobulin that allow the tumor cells to now evolve below the radar, so to speak. But you allude to the sort of spatial technologies that allow us to start to interpret the microenvironments as well. And that then tells us what the evolutionary pressures are upon the tumor. And we're learning from those spatial technologies that these environments are incredibly diverse, actually interestingly seem to be converging on one important aspect I'd like to talk to you a little bit more about, which is the myeloid axis, which is these neutrophils, macrophages, et cetera, that seem to be associated with poor outcome and that will perhaps talk about pollution in a minute.(25:51):But I think they're creating a sort of chronic inflammatory response that allows these early nascent tumor cells to start to initiate into frankly tumor invasive cells and start to grow. And so, what we're seeing from these spatial technologies in lung cancer is that T-cells, predatory T-cells, force tumors to lose their HLA molecules and what have you to evade the immune system. But for reasons we don't understand, high neutrophil infiltration seems to be associated with poor outcome, poor metastasis free survival. And actually, those same neutrophils we've recently found actually even tracked to the metastasis sites of metastasis. So it's almost like this sort of symbiosis between the myeloid cells and the tumor cells in their biology and growth and progression of the tumor cells.Eric Topol (26:46):Yeah, I mean this white cell story, this seems to be getting legs and is relatively new, was this cracked because of the ability to do this type of work to in the past everything was, oh, it's cancer's heterogeneous and now we're getting pinpoint definition of what's going on.Charles Swanton (27:04):I think it's certainly contributed, but it's like everything in science, Eric, when you look back, there's evidence in the literature for pretty much everything we've ever discovered. You just need to put the pieces together. And I mean one example would be the neutrophil lymphocyte ratio in the blood as a hallmark of outcome in cancers and to checkpoint inhibitor blockade, maybe this begins to explain it, high neutrophils, immune suppressive environment, high neutrophils, high macrophages, high immune suppression, less benefit from checkpoint inhibitor therapy, whereas you want lymphocyte. So I think there are biomedical medical insights that help inform the biology we do in the lab that have been known for decades or more. And certainly the myeloid M2 axis in macrophages and what have you was known about way before these spatial technologies really came to fruition, I think.The Impact of Air PollutionEric Topol (28:01):Yeah. Well you touched on this about air pollution and that's another dimension of the work that you and your team have done. As you well know, there was a recent global burden of disease paper in the Lancet, which has now said that air pollution with particulate matter 2.5 less is the leading cause of the burden of disease in the world now.Charles Swanton (28:32):What did you think of that, Eric?Eric Topol (28:34):I mean, I was blown away. Totally blown away. And this is an era you've really worked on. So can you put it in perspective?Charles Swanton (28:42):Yeah. So we got into this because patients of mine, and many of my colleagues would ask the same question, I've never smoked doctor, I'm healthy. I'm in my mid 50s though they're often female and I've got lung cancer. Why is that doctor? I've had a good diet, I exercise, et cetera. And we didn't really have a very good answer for that, and I don't want to pretend for a minute we solved the whole problem. I think hopefully we've contributed to a little bit of understanding of why this may happen. But that aside, we knew that there were risk factors associated with lung cancer that included air pollution, radon exposure, of course, germline genetics, we mustn't forget very important germline variation. And I think there is evidence that all of them are associated with lung cancer risk in different ways. But we wanted to look at air pollution, particularly because there was an awful lot of evidence, several meta-analysis of over half a million individuals showing very convincingly with highly significant results that increasing PM 2.5 micron particulate levels were associated with increased risk of lung cancer.(29:59):To put that into perspective, where you are on the west coast of the US, it's relatively unpolluted. You would be talking about maybe five micrograms per meter cubed of PM2.5 in a place like San Diego or Western California, assuming there aren't any forest fires of course. And we estimate that that would translate to about, we think it's about one extra case of never smoking lung cancer per hundred thousand of the population per year per one microgram per meter cube rise in the pollution levels. So if you go to Beijing for example, on a bad day, the air pollution levels could be upwards of a hundred micrograms per meter cubed because there are so many coal fired power stations in China partly. And there I think the risk is considerably higher. And that's certainly what we've seen in the meta-analyses in our limited and relatively crude epidemiological analyses to be the case.(30:59):So I think the association was pretty certain, we were very confident from people's prior publications  this was important. But of course, association is not causation. So we took a number of animal models and showed that you could promote lung cancer formation in four different oncogene driven lung cancer models. And then the question is how, does air pollution stimulate mutations, which is what I initially thought it would do or something else. It turns out we don't see a significant increase in exogenous like C to A carcinogenic mutations. So that made us put our thinking caps on. And I said to you earlier, often all these discoveries have been made before. Well, Berenblum in 1947, first postulated that actually tumors are initiated through a two-step process, which we now know involves a sort of pre initiated cell with a mutation in that in itself is not sufficient to cause cancer.(31:58):But on top of that you need an inflammatory stimulus. So the question was then, well, okay, is inflammation working here? And we found that there was an interleukin-1 beta axis. And what happens is that the macrophages come into the lung on pollution exposure, engulf phagocytose the air pollutants, and we think what's happening is the air pollutants are puncturing membranes in the lung. That's what we think is happening. And interleukin-1 beta preformed IL-1 beta is being released into the extracellular matrix and then stimulating pre-initiated cells stem cells like the AT2 cells with an activating EGFR mutation to form a tumor. But the EGFR mutation alone is not sufficient to form tumors. It's only when you have the interleukin-1 beta and the activated mutation that a tumor can start.(32:49):And we found that if we sequence normal lung tissue in a healthy adult 60-year-old adult, we will find about half of biopsies will have an activating KRAS mutation in normal tissue, and about 15% will have an activating mutation in EGFR in histologically normal tissue with nerve and of cancer. In fact, my friend and colleague who's a co-author on the paper, James DeGregori, who you should speak to in Colorado, fascinating evolutionary cancer biologists estimates that in a healthy 60-year-old, there are a hundred billion cells in your body that harbor an oncogenic mutation. So that tells you that at the cellular level, cancer is an incredibly rare event and almost never happens. I mean, our lifetime risk of cancer is perhaps one in two. You covered that beautiful pancreas paper recently where they estimated that there may be 80 to 100 KRAS mutations in a normal adult pancreas, and yet our lifetime risk of pancreas cancer is one in 70. So this tells you that oncogenic mutations are rarely sufficient to drive cancer, so something else must be happening. And in the context of air pollution associated lung cancer, we think that's inflammation driven by these white cells, these myeloid cells, the macrophages.Cancer BiomarkersEric Topol (34:06):No, it makes a lot of sense. And this, you mentioned the pancreas paper and also what's going in the lung, and it seems like we have this burden of all you need is a tipping point and air pollution seems to qualify, and you seem to be really in the process of icing the mechanism. And like I would've thought it was just mutagenic and it's not so simple, right? But that gets me to this is such an important aspect of cancer, the fact that we harbor these kind of preconditions. And would you think that cancer takes decades to actually manifest most cancers, or do we really have an opportunity here to be able to track whether it's through blood or other biomarkers? Another area you've worked on a lot whereby let's say you could define people at risk for polygenic risk scores or various cancers or genome sequencing for predisposition genes, whatever, and you could monitor in the future over the course of those high-risk people, whether they were starting to manifest microscopic malignancy. Do you have any thoughts about how long it takes for the average person to actually manifest a typical cancer?Charles Swanton (35:28):That's a cracking question, and the answer is we've got some clues in various cancers. Peter Campbell would be a good person to speak to. He estimates that some of the earliest steps in renal cancer can occur in adolescence. We've had patients who gave up smoking 30 or so years ago where we can still see the clonal smoking mutations in the trunk of the tumor's evolutionary tree. So the initial footprints of the cancer are made 30 years before the cancer presents. That driver mutation itself may also be a KRAS mutation in a smoking cigarette context, G12C mutation. And those mutations can precede the diagnosis of the disease by decades. So the earliest steps in cancer evolution can occur, we think can precede diagnoses by a long time. So to your point, your question which is, is there an opportunity to intervene? I'm hugely optimistic about this actually, this idea of molecular cancer prevention.An Anti-Inflammatory Drug Reduces Fatal Cancer and Lung Cancer(36:41):How can we use data coming out of various studies in the pancreas, mesothelioma, lung, et cetera to understand the inflammatory responses? I don't think we can do very much about the mutations. The mutations unfortunately are a natural consequence of aging. You and I just sitting here talking for an hour will have accumulated multiple mutations in our bodies over that period, I'm afraid and there's no escaping it. And right now there's not much we can do to eradicate those mutant clones. So if we take that as almost an intractable problem, measuring them is hard enough, eradicating them is even harder. And then we go back to Berenblum in 1947 who said, you need an inflammatory stimulus. Well, could we do something about the inflammation and dampen down the inflammation? And of course, this is why we got so excited about IL-1 beta because of the CANTOS trial, which you may remember in 2017 from Ridker and colleagues showed that anti IL-1 beta used as a mechanism of preventing cardiovascular events was associated with a really impressive dose dependent reduction in new lung cancer primaries.(37:49):Really a beautiful example of cancer prevention in action. And that data weren't just a coincidence. The FDA mandated Novartis to collect the solid tumor data and the P-values are 0.001. I mean it's very highly significant dose dependent reduction in lung cancer incidents associated with anti IL-1 beta. So I think that's really the first clue in my mind that something can be done about this problem. And actually they had five years of follow-up, Eric. So that's something about that intervening period where you can treat and then over time see a reduction in new lung cancers forming. So I definitely think there's a window of opportunity here.Eric Topol (38:31):Well, what you're bringing up is fascinating here because this trial, which was a cardiology trial to try to reduce heart attacks, finds a reduction in cancer, and it's been lost. It's been buried. I mean, no one's using this therapy to prevent cancer between ratcheting up the immune system or decreasing inflammation. We have opportunities that we're not even attempting. Are there any trials that are trying to do this sort of thing?Charles Swanton (39:02):So this is the fundamental problem. Nobody wants to invest in prevention because essentially you are dealing with well individuals. It's like the vaccine challenge all over again. And the problem is you never know who you are benefiting. There's no economic model for it. So pharma just won't touch prevention with a barge pole right now. And that's the problem. There's no economic model for it. And yet the community, all my academic colleagues are crying out saying, this has got to be possible. This has got to be possible. So CRUK are putting together a group of like-minded individuals to see if we can do something here and we're gradually making progress, but it is tough.Eric Topol (39:43):And it's interesting that you bring that up because for GRAIL, one of the multicenter cancer early detection companies, they raised billions of dollars. And in fact, their largest trial is ongoing in the UK, but they haven't really focused on high-risk people. They just took anybody over age 50 or that sort of thing. But that's the only foray to try to reboot how we or make an early microscopic diagnosis of cancer and track people differently. And there's an opportunity there. You've written quite a bit on you and colleagues of the blood markers being able to find a cancer where well before, in fact, I was going to ask you about that is, do you think there's people that are not just having all these mutations every minute, every hour, but that are starting to have the early seeds of cancer, but because their immune system then subsequently kicks in that they basically kind of quash it for that period of time?Charles Swanton (40:47):Yeah, I do think that, I mean, the very fact that we see these sort of footprints in the tumor genome of immune evasion tells you that the immune system's having a very profound predatory effect on evolving tumors. So I do think it's very likely that there are tumors occurring that are suppressed by the immune system. There is a clear signature, a signal of negative selection in tumors where clones have been purified during their evolution by the immune system. So I think there's pretty strong evidence for that now. Obviously, it's very difficult to prove something existed when it doesn't now exist, but there absolutely is evidence for that. I think it raises the interesting question of immune system recognizes mutations and our bodies are replete with mutations as we were just discussing. Why is it that we're not just a sort of epithelial lining of autoimmunity with T-cells and immune cells everywhere? And I think what the clever thing about the immune system is it's evolved to target antigens only when they get above a certain burden. Otherwise, I think our epithelial lining, our skin, our guts, all of our tissues will be just full of T-cells eating away our normal clones.(42:09):These have to get to a certain size for antigen to be presented at a certain level for the immune system to recognize it. And it's only then that you get the immune predation occurring.Forever Chemicals and Microplastics Eric Topol (42:20):Yeah, well, I mean this is opportunities galore here. I also wanted to extend the air pollution story a bit. Obviously, we talked about particulate matter and there's ozone and nitric NO2, and there's all sorts of other air pollutants, but then there's also in the air and water these forever chemicals PFAS for abbreviation, and they seem to be incriminated like air pollution. Can you comment about that?Charles Swanton (42:55):Well, I can comment only insofar as to say I'm worried about the situation. Indeed, I'm worried about microplastics actually, and you actually cover that story as well in the New England Journal, the association of microplastics with plaque rupture and atheroma. And indeed, just as in parenthesis, I wanted to just quickly say we currently think the same mechanisms that are driving lung cancer are probably responsible for atheroma and possibly even neurodegenerative disease. And essentially it all comes down to the macrophages and the microglia becoming clogged up with these pollutants or environmental particulars and releasing chronic inflammatory mediators that ultimately lead to disease. And IL-1 beta being one of those in atheroma and probably IL-6 and TNF in neurodegenerative disease and what have you. But I think this issue that you rightly bring up of what is in our environment and how does it cause pathology is really something that epidemiologists have spent a lot of time focusing on.(43:56):But actually in terms of trying to move from association to causation, we've been, I would argue a little bit slow biologically in trying to understand these issues. And I think that is a concern. I mean, to give you an example, Allan Balmain, who works at UCSF quite close to you, published a paper in 2020 showing that 17 out of 20 environmental carcinogens IARC carcinogens class one carcinogens cause tumors in rodent models without driving mutations. So if you take that to a logical conclusion, in my mind, what worries me is that many of the sort of carcinogen assays are based on driving mutagenesis genome instability. But if many carcinogen aren't driving DNA mutagenesis but are still driving cancer, how are they doing it? And do we actually have the right assays to interpret safety of new chemical matter that's being introduced into our environment, these long-lived particles that we're breathing in plastics, pollutants, you name it, until we have the right biological assays, deeming something to be safe I think is tricky.Eric Topol (45:11):Absolutely. And I share your concerns on the nanoplastic microplastic story, as you well know, not only have they been seen in arteries that are inflamed and in blood clots and in various tissues, have they been seen so far or even looked for within tumor tissue?Charles Swanton (45:33):Good question. I'm not sure they have. I need to check. What I can tell you is we've been doing some experiments in the lab with fluorescent microplastics, 2.5 micron microplastics given inhaled microplastics. We find them in every mouse organ a week after. And these pollutants even get through into the brain through the olfactory bulb we think.Charles Swanton (45:57):Permeate every tissue, Eric.Eric Topol (45:59):Yeah, no, this is scary because here we are, we have these potentially ingenious ways to prevent cancer in the future, but we're chasing our tails by not doing anything to deal with our environment.Charles Swanton (46:11):I think that's right. I totally agree. Yeah.Eric Topol (46:15):So I mean, I can talk to you for the rest of the day, but I do want to end up with a topic that we have mutual interest in, which is AI. And also along with that, when you mentioned about aging, I'd like to get your views on these two, how do you see AI fitting into the future of cancer? And then the more general topic is, can we actually at some point modulate the biologic aging process with or without help with from AI? So those are two very dense questions, but maybe you can take us through them.Charles Swanton (46:57):How long have we got?Eric Topol (46:59):Just however long you have.A.I. and CancerCharles Swanton (47:02):AI and cancer. Well, AI and medicine actually in general, whether it's biomedical research or medical care, has just infinite potential. And I'm very, very excited about it. I think what excites me about AI is it's almost the infinite possibilities to work across scale. Some of the challenges we raised in the Cell review that you mentioned, tackling, embracing complexity are perfectly suited for an AI problem. Nonlinear data working, for instance in our fields with CT imaging, MRI imaging, clinical outcome data, blood parameters, genomics, transcriptomes and proteomes and trying to relate this all into something that's understandable that relates to risk of disease or potential identification of a new drug target, for example. There are numerous publications that you and others have covered that allude to the incredible possibilities there that are leading to, for instance, the new identification of drug targets. I mean, Eli Van Allen's published some beautiful work here and in the context of prostate cancer with MDM4 and FGF receptor molecules being intimately related to disease biology.(48:18):But then it's not just that, not just drug target identification, it's also going all the way through to the clinic through drug discovery. It's how you get these small molecules to interact with oncogenic proteins and to inhibit them. And there are some really spectacular developments going on in, for instance, time resolved cryo-electron microscopy, where in combination with modeling and quantum computing and what have you, you can start to find pockets emerging in mutant proteins, but not the wild type ones that are druggable. And then you can use sort of synthetic AI driven libraries to find small molecules that will be predicted to bind these transiently emerging pockets. So it's almost like AI is primed to help at every stage in scientific investigation from the bench all the way through to the bedside. And there are examples all the way through there in the literature that you and others have covered in the last few years. So I could not be more excited about that.Eric Topol (49:29):I couldn't agree with you more. And I think when we get to multimodal AI at the individual level across all their risks for conditions in their future, I hope someday will fulfill that fantasy of primary prevention. And that is getting me to this point that I touched on because I do think they interact to some degree AI and then will we ever be able to have an impact on aging? Most people conflate this because what we've been talking about throughout the hour has been age-related diseases, that is cancer, for example, and cardiovascular and neurodegenerative, which is different than changing aging per se, body wide aging. Do you think we'll ever changed body wide aging?Charles Swanton (50:18):Wow, what a question. Well, if you'd asked me 10 years ago, 15 years ago, do you think we'll ever cure melanoma in my lifetime, I'd have said definitely not. And now look where we are. Half of patients with melanoma, advanced melanoma, even with brain metastasis curd with combination checkpoint therapy. So I never say never in biology anymore. It always comes back to bite you and prove you wrong. So I think it's perfectly possible.Charles Swanton (50:49):We have ways to slow down the aging process. I guess the question is what will be the consequences of that?Eric Topol (50:55):That's what I was going to ask you, because all these things like epigenetic reprogramming and senolytic drugs, and they seem to at least pose some risk for cancer.Charles Swanton (51:09):That's the problem. This is an evolutionary phenomenon. It's a sort of biological response to the onslaught of these malignant cells that are potentially occurring every day in our normal tissue. And so, by tackling one problem, do we create another? And I think that's going to be the big challenge over the next 50 years.Eric Topol (51:31):Yeah, and I think your point about the multi-decade challenge, because if you can promote healthy aging without any risk of cancer, that would be great. But if the tradeoff is close, it's not going to be very favorable. That seems to be the main liability of modulation aging through many of the, there's many shots on goal here, of course, as you well know. But they do seem to pose that risk in general.Charles Swanton (51:58):I think that's right. I think the other thing is, I still find, I don't know if you agree with me, but it is an immense conundrum. What is the underlying molecular basis for somatic aging, for aging of normal tissues? And it may be multifactorial, it may not be just one answer to that question. And different tissues may age in different ways. I don't know. It's a fascinating area of biology, but I think it really needs to be studied more because as you say, it underpins all of these diseases we've been talking about today, cardiovascular, neurodegeneration, cancer, you name it. We absolutely have to understand this. And actually, the more I work in cancer, the more I feel like actually what I'm working on is aging.(52:48):And this is something that James DeGregori and I have discussed a lot. There's an observation that in medicine around patients with alpha-1 antitrypsin deficiency who are at higher risk of lung cancer, but they're also at high risk of COPD, and we know the associations of chronic obstructive pulmonary disease with lung cancer risk. And one of the theories that James had, and I think this is a beautiful idea, actually, is as our tissues age, and COPD is a reflection of aging, to some extent gone wrong. And as our tissues age, they become less good at controlling the expansion of these premalignant clones, harboring, harboring oncogenic mutations in normal tissue. And as those premalignant clones expand, the substrate for evolution also expands. So there's more likely to be a second and third hit genetically. So it may be by disrupting the extracellular matrices through inflammation that triggers COPD through alpha-1 antitrypsin deficiency or smoking, et cetera, you are less effectively controlling these emergent clones that just expand with age, which I think is a fascinating idea actually.Eric Topol (54:01):It really is. Well, I want to tell you, Charlie, this has been the most fascinating, exhilarating discussion I've ever had on cancer. I mean, really, I am indebted to you because not just all the work you've done, but your ability to really express it, articulate it in a way that hopefully everyone can understand who's listening or reading the transcript. So we'll keep following what you're doing because you're doing a lot of stuff. I can't thank you enough for joining me today, and you've given me lots of things to think about. I hope the people that are listening or reading feel the same way. I mean, this has been so mind bending in many respects. We're indebted to you.Charles Swanton (54:49):Well, we all love reading your Twitter feeds. Keep them coming. It helps us keep a broader view of medicine and biological research, not just cancer, which is why I love it so much.******************************************The Ground Truths newsletters and podcasts are all free, open-access, without ads.Please share this post/podcast with your friends and network if you found it informativeVoluntary paid subscriptions all go to support Scripps Research.

This conversation sees the end of the "hot topics" discussion, followed by Michael Charlton discussing issues and excitement around the FGF-21 class.As we begin, Louise Campbell and Jörn Schattenberg speculate on ways to incorporate metrics like the Dietary Inflammation Index into multifactorial care. Michael asks whether alcohol is figured in the index, given its pro-inflammatory nature, and celebrates the fact that we can now evaluate MetALD patients as a group instead of removing them from classical MASH clinical trials. Louise, who raised the issue in the first place, does not know. As she notes, she first found the issue within the last week. One key question for her is how we can use this in 5-10 years when primary care becomes a key player in MASLD and all metabolic diseases. Roger Green's hot topic involves "Ask the MD" columns in US newspapers and magazines. He gives "two cheers" for help columns in which MDs recommend that MASH patients  "go to your doctor and ask for an ultrasound."  He asks whether the PCP is the right destination and whether "ultrasound is the test to seek. However, he appreciates that all this brings MASH badly-needed visibility in the public eye. Michael and Louise agree that given how few patients are treated today, any such public acknowledgment is positive.Michael discusses the emerging excitement around the FGF-21 class. The recent agents from Akero and 89bio are "emerging as highly potent" in terms of PDFF change and transaminase responses. While we need to learn more, he asks how this will fit in with Rezdiffra and, more generally, how long we can give a patient a "potent" growth factor and what will happen if/when the patient needs to discontinue therapy. Jörn and Michael note adherence challenges with this therapy; Roger comments that even with daily oral drugs, adherence can be a challenge.

This final conversation starts by considering prescribing models for other diseases and how they might work here, shifts to discussing the challenges of keeping a patient enrolled in a long-term clinical trial (or even participating in a trial in the first place), and moves on to the final question for the episode. The conversation picks up on the FG-21 conversation, particularly how FGF-21 might be prescribed alongside Rezdiffra. Roger Green starts by asking whether and how this prescribing pattern might fit in an "oncology" model, where FGF-21 might be an induction drug and Rezdiffra a maintenance drug. Michael Charlton suggests that benefits from FGF-21s are likely to fade once therapy is discontinued, which would make this model suboptimal.Jörn Schattenberg raises the issue of keeping patients in the long-term clinical trials necessary to achieve hard outcomes. Jörn advocates keeping his patients in trials but notes that long-term compliance will become increasingly challenging as more therapeutic options become available and the patient may not be improving. Michael suggests we will find similar challenges in recruitment for new trials if patients have to accept the possibility of receiving a placebo. Roger notes that biopsy requirements increase this challenge. As the episode winds down, Roger asks participants what they believe are exciting studies likely to come to light over the next three months. Their answers vary. You'll have to listen to learn. 

Michael Charlton joins Jörn Schattenberg, Louise Campbell, and Roger Green for a far-reaching conversation that covers ways Rezdiffra is already impacting MASH patient treatment, exciting recent studies and broader issues in clinical trial recruitment.  00:00:00 - Surf's Up: Season 5 Episode 11Opening comments from the panel, including brief quotes taken directly from the episode. 00:02:32 - IntroductionOpening comments (re)introducing listeners to Michael Charlton00:04:34 - GroundbreakersEach panelist shares one piece of good news from the previous week.00:06:56 - Impact of Rezdiffra launch on Michael's clinic Michael hails Rezdiffra as "an amazing thing" in terms of its global impact. He goes on to discuss the challenges his clinic faces in properly defining the target F2/F3 patient. 00:14:40 - Defining positive response and treatment futility In response to a question from Louise, Michael indicates that he will continue patients on Rezdiffra as long as they do not progress. 00:19:44 - LiverRISK scoreThe conversation shifts to focus on progress in translational medicine. The first item Michael cites is LiverRIsk, which he terms "substantially superior" to other biomarkers. Next, he mentions his group's work on the microbiome and the challenges in translating items like these into clinically meaningful interventions.00:23:15 - Low-dose aspirin as anti-MASH medicine Michael discusses the recent JAMA publication of a small RCT suggesting benefits from use of low-dose aspirin in biopsy-confirmed MASLD patients.  He and Jörn agree that while the sample size was small, the "highly promising" results might be worthy of discussion with patients.00:26:29 - Jörn and Louise share their items of interestJörn discusses his excitement about the upcoming Innovations in SLD Think-Tank 2024 and its new format. Louise discusses a study indicating correlation between the Dietary Inflammation index score and kilopascal levels. 00:33:27 – Questions about the Dietary Inflammation Index Louise and Jörn speculate on ways to incorporate this kind of result into multifactorial care. Michael asks whether alcohol figured in the index given that many MASH patients consume alcohol. 00:35:38 - Roger on patient feedbackRoger asks how panelists feel about MD columnists recommending that MASH patients  "go to your doctor and ask for an ultrasound."  Michael and Louise agree that given how few patients are treated today, any such public acknowledgment is positive.00:38:11 - Excitement and questions surrounding FGF-21sMichael discusses the emerging excitement around the FGF-21 class. "emerging as highly potent" and asks questions its use and long-term value to patients. The group discusses adherence challenges with a q1w injectable therapy. 00:41:26 Therapeutic models for MASH prescribing Roger asks whether prescribing for FGF-21s might align with an "oncology" model, with FGF-21 as induction drug and Rezdiffra as maintenance drug. Michael suggests that benefits from FGF-21s are likely to fade once therapy is discontinued. 00:43:08 - Challenges in clinical trial recruitment and adherenceJörn, Michael and Roger all agree on the growing challenge of keeping patients in the long-term clinical trials necessary to achieve hard outcomes.00:47:24 - Closing questionRoger asks participants what they believe are exciting studies likely to come to light over the next three months. 00:49:33 - Question of the WeekThe question asks how much value old standard drugs like aspirin or pioglitazone are likely to bring to MASH or MASLD patient treatment.00:50:22 - Business ReportThis week's news on audience metrics, SurfingMASH sponsorship, spring events and this week's Vault conversation.

Dr. Noah Davidsohn, co-founder and CSO of Rejuvenate Bio, discusses the company's innovative work using gene therapies to treat age-related diseases in dogs and humans. In his conversation with host Chris Patil, he explains his recent groundbreaking study showing that partial cellular reprogramming with Yamanaka factors extended lifespan and healthspan in very old mice. Noah then outlines Rejuvenate's clinical pipeline, including targeting longevity pathways like FGF-21 for heart disease and combining TGF-beta inhibition with klotho for osteoarthritis. By choosing secreted factors deliverable with liver-targeted gene therapy, Rejuvenate hopes to circumvent delivery challenges. Noah conveys an inspiring vision of adding healthy years to dogs' and humans' lives.Key Topics Covered:Rejuvenate Bio's mission to reverse aging and age-related diseaseLifespan doubling in old mice with cyclic Yamanaka factor inductionControllable gene therapy system for in vivo partial reprogrammingChoice of FGF-21 for pleiotropic effects deliverable from liverLead programs for arrhythmogenic cardiomyopathy and mitral valve diseaseAdvantages of treating age-related diseases first in dogsCombination gene therapy for osteoarthritis: TGF-beta and klothoSecreted proteins enable broad effects without broad deliveryVision of expanding healthspan by "squaring the curve"Potential to keep people healthy, active and productive to 100+

In the realm of regenerative medicine, BPC-157 (Body Protection Compound-157) has emerged as a promising peptide for its potential to promote healing and address inflammation. From injuries and inflammation to gut health and brain fog, BPC-157 has been shown to promote a wide range of healing properties in many animal studies.  In this podcast, we'll talk about the intricate mechanisms through which BPC-157 for many different health conditions. Tissue Repair and Injuries: BPC-157 has been shown to accelerate tissue repair and regeneration. It works by stimulating the formation of new blood vessels, a process known as angiogenesis. This increases blood flow to the injured site in order to deliver essential nutrients and oxygen to help facilitate the healing process Additionally, BPC-157 modulates the activity of growth factors involved in tissue regeneration, such as VEGF (Vascular Endothelial Growth Factor) and FGF-2 (Fibroblast Growth Factor 2), thereby promoting the proliferation of fibroblasts and other cells crucial for wound healing. Pain Caused by Inflammation and Joint Pain: Inflammation is a common underlying factor in many painful conditions, including back pain (e.g., muscle strains, degenerative disc disease, or arthritis) and joint pain due to inflammatory disorders (e.g., osteoarthritis or rheumatoid arthritis).  BPC-157 exhibits potent anti-inflammatory properties, suppressing the production of pro-inflammatory cytokines like TNF-alpha and interleukins. By dampening the inflammatory response, BPC-157 helps alleviate pain and discomfort associated with inflammation. Moreover, BPC-157 may exert protective effects on cartilage and joint tissues, contributing to its potential to manage joint pain and promote musculoskeletal health. Gut Health: The gastrointestinal tract is a complex ecosystem that plays a vital role in overall health and well-being. In fact, clinical studies show that your gut health is important for your heart health. It's also associated with many other health conditions like obesity, insulin resistance, diabetes, depression, and inflammatory bowel disease.  BPC-157 has been extensively studied in animals for its gastroprotective effects, particularly in conditions characterized by gut inflammation and injury. This peptide promotes the repair and regeneration of damaged gastrointestinal tissues, enhances mucosal integrity of the stomach lining, and reduces inflammation within the gut. Moreover, BPC-157 may modulate gut microbiota composition, contributing to a healthy gut microbiome and improved digestive function. Skin Burns: Skin burns pose significant challenges in wound healing and tissue regeneration. In animal studies, BPC-157 has shown remarkable efficacy in promoting the healing of skin burns by accelerating the formation of new skin tissue and reducing inflammation. It works by enhancing the migration and proliferation of skin cells, leading to faster wound closure and improved wound healing outcomes. Additionally, BPC-157 exhibits antioxidant properties, protecting skin cells from oxidative stress (when there are too many free radicals and not enough antioxidants). This helps cells survive and speeds up the healing process. Corneal Injuries: The cornea (the clear covering over the front of the eye) is susceptible to injuries and infections that can impair vision. BPC-157 has emerged as a potential therapeutic agent for promoting corneal wound healing and reducing inflammation in the eye. Through its angiogenic and anti-inflammatory effects, BPC-157 accelerates the repair of corneal injuries, enhances epithelial cell proliferation, and promotes tissue regeneration.  Brain Fog: Brain fog, characterized by thinking that feels cloudy or slow, can significantly impact daily functioning. BPC-157 exhibits neuroprotective effects and may help alleviate symptoms of brain fog by promoting neuronal survival and regeneration. Moreover, BPC-157 modulates neurotransmitter activity and reduces neuroinflammation, thereby enhancing cognitive function and mental clarity.  Thanks again for listening to The Peptide Podcast.

This week on FGF, Tay & Bri are talking radioactive wastewater, how hangin' with your buds for no reason will save your life, and why planes are almost running into each other a lot more than you would hope they do. Also, the AI revolution is the utopia that Taylor is waiting for. Let's wrap this week up with some good vibes and some heavy laughs.
