BUFFALO, NY – June 27, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on June 17, 2025, titled “Molecular landscape of HER2-mutated non-small cell lung cancer in Northeastern Brazil: Clinical, histopathological, and genomic insights.” In this study, researchers led by first authors Cleto Dantas Nogueira from the Federal University of Ceará and Argos Pathology Laboratory and Samuel Frota from Argos Pathology Laboratory, along with corresponding author Fabio Tavora from the previously mentioned institutions and Messejana Heart and Lung Hospital, investigated how HER2 gene mutations appear in cases of non-small cell lung cancer (NSCLC) in Northeastern Brazil. The team found that HER2 mutations showed significant genetic diversity and were often associated with other cancer-related genetic changes. These findings revealed diagnostic and treatment challenges in a population that is rarely studied, emphasizing the need for expanded access to molecular testing and targeted therapies. HER2 mutations are a known factor in several cancers, including breast and gastric cancers. In lung cancer—particularly NSCLC—these mutations are less common but remain clinically significant. Most existing research on HER2-mutated lung cancer focuses on high-income countries, leaving important gaps in knowledge about underrepresented regions such as Latin America. This study helps fill that gap by analyzing 13 patients with HER2-mutated NSCLC using clinical, pathological, and genomic data. The patients ranged in age from 34 to 82 years, and more than half were women. About half had never smoked. Their tumors often displayed complex genetic profiles, including additional mutations in genes such as TP53, KRAS, and STK11. The most common HER2 mutation identified was an insertion in exon 20, a known hotspot for activating mutations. “Trastuzumab deruxtecan (T-DXd) is the first HER2-targeted agent to show clinical efficacy in HER2-mutant non-small cell lung cancer (HER2m NSCLC).” Treatment strategies among the patients varied. Only one individual received HER2-targeted therapy. Most were treated with surgery, chemotherapy, immunotherapy, or a combination of these approaches. Outcomes also differed, with some patients surviving for years and others dying within months of diagnosis. These findings reinforce the need for early diagnosis and improved access to advanced treatments, particularly in low-resource settings. The study emphasizes the value of comprehensive molecular profiling in NSCLC. Because HER2 mutations often occur alongside other genetic alterations, full genomic analysis is crucial for guiding treatment decisions. Yet, such testing is not always available. The researchers propose a tiered diagnostic approach, beginning with basic screening and expanding to more advanced tests when necessary, to enhance patient care. This study provides valuable insights into the molecular characteristics of HER2-mutated NSCLC in a Brazilian population, highlighting the complexity and clinical relevance of these alterations. Larger studies are needed to clarify the prevalence and prognostic significance of HER2 mutations, as well as their impact on treatment response and survival. This knowledge is essential for advancing effective HER2-targeted therapies. The findings also support broader implementation of international clinical guidelines in Latin America and highlight the critical need to include underrepresented populations in cancer research.

Dr. Vamsi Velcheti and Dr. Nate Pennell discuss novel treatment approaches in small cell and non-small cell lung cancer that were featured at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Vamsi Velcheti: Hello, I'm Dr. Vamsi Velcheti, your guest host of the ASCO Daily News Podcast. I'm a professor of medicine and chief of hematology and oncology at the Mayo Clinic in Jacksonville, Florida. The 2025 ASCO Annual Meeting featured some exciting advancements in small cell lung cancer, targeted therapies for non-small cell lung cancer, and other novel [treatment] approaches. Today, I'm delighted to be joined by Dr. Nate Pennell to discuss some of the key abstracts that are advancing the lung cancer field. Dr. Pennell is the co-director of the Cleveland Clinic Lung Cancer Program and also the vice chair of clinical research at the Taussig Cancer Institute. Our full disclosures are available in the transcript of this episode. Nate, it's great to have you back on the podcast. Thanks so much for being here. Dr. Nate Pennell: Thanks, Vamsi. Always a pleasure. Dr. Vamsi Velcheti: Let's get started, and I think the first abstract that really caught my attention was Abstract 8516, “The Randomized Trial of Relevance of Time of Day of Immunotherapy for Progression-Free and Overall Survival in Patients With Non-Small Cell Lung Cancer.” What are your thoughts about this, Nate? Dr. Nate Pennell: I agree. I thought this was one of the most discussed abstracts, certainly in the lung cancer session, but I think even outside of lung cancer, it got some discussion. So, just to put this in perspective, there have been a number of publications that have all been remarkably consistent, and not just in lung cancer but across multiple cancer types, that immunotherapy, immune checkpoint inhibitors, are commonly used. And all of them have suggested, when looking at retrospective cohorts, that patients who receive immune checkpoint inhibitors earlier in the day – so in the morning or before the early afternoon – for whatever reason, appear to have better outcomes than those who get it later in the day, and this has been repeated. And I think many people just sort of assumed that this was some sort of strange association and that there was something fundamentally different from a prognostic standpoint in people who came in in the morning to get their treatment versus those who came later in the afternoon, and that was probably the explanation. The authors of this randomized trial actually decided to test this concept. And so, about 210 patients with previously untreated advanced non-small cell lung cancer were randomly assigned to get chemo and immune checkpoint inhibitor – either pembrolizumab or sintilimab – and half of them were randomly assigned to get the treatment before 3 PM in the afternoon, and half of them were assigned to get it after 3 PM in the afternoon. And it almost completely recapitulated what was seen in the retrospective cohorts. So, the median progression-free survival in those who got earlier treatment was 13.2 months versus only 6.5 months in those who got it later in the day. So, really enormous difference with a hazard ratio of 0.43, which was statistically significant. And perhaps even more striking, the median overall survival was not reached in the early group versus 17.8 months in the late group with a hazard ratio of 0.43, also highly statistically significant. Even the response rate was 20% higher in the early patients; 75% response rate compared to 56% in the late-time-of-day patients. So very consistent across all measures of efficacy with pretty good matched characteristics across the different groups. And so, I have to tell you, I don't know what to make of this. I certainly was a skeptic about the retrospective series, but now we have a prospective randomized trial that shows essentially the same thing. So, maybe there is a difference between getting treated in the morning, although I have yet to hear someone give a very good mechanistic explanation as to why this would be. What were your thoughts on this? Dr. Vamsi Velcheti: It's indeed fascinating, Nate, and I actually think this was a very interesting abstract. Really, I was caught off guard looking at the data. I mean, if it were a drug, we would be so excited, right? I mean, with those kind of survival benefits. I don't know. I think circadian rhythm probably has something to do with it, like different cytokine profiles at the time of administration. I mean, who knows? But I think it's a randomized trial, and I think I would expect to see a mad rush for treatment appointments early in the morning given this, and at least I want my patients to come in first thing in the morning. It'll be interesting to see. Dr. Nate Pennell: It's important to point out that in this study, everyone got chemo and immunotherapy. And, at least in our cancer center, most patients who are getting platinum-doublet chemotherapy and immunotherapy actually do get treated earlier in the day already, just because of the length of the infusion appointment that's needed. So it really is oftentimes people getting single-agent immunotherapy who are often getting the later, shorter visits. But if you have a choice, I think it would be very reasonable to have people treated earlier in the day. And I do think most of the impressions that I got from people about this is that they would like to see it reproduced but certainly well worth further investigation. And I personally would like to see more investigation into what the rationale would be for this because I still can't quite figure out, yes, if you got it at, say, you know, 5 PM, that's later in the day and I can understand that maybe your immune system is somewhat less receptive at that point than it would be in the morning. But because these checkpoint inhibitors have such long half-lives, it's still in your system the next morning when your immune system is supposedly more receptive. So I don't quite understand why that would be the case. Well, let's move on to the next study. I would like to hear your thoughts on Abstract 8515, “Plasma-Guided, Adaptive First-Line Chemoimmunotherapy for Non-Small Cell Lung Cancer.” Dr. Vamsi Velcheti: Yeah, this was another abstract that seems to be really interesting in my opinion. I think there's kind of a lot of emphasis lately on ctDNA and MRD-based assays to monitor disease. In the lung cancer space, we haven't had a lot of clinical trials looking at this prospectively, and this was one of those pilot studies where they looked at circulating free DNA (cfDNA)-based response-adaptive strategy for frontline patients who are PD-L1 positive. So, patients started with pembrolizumab monotherapy, and based on plasma molecular response after 2 cycles, those patients without response received early treatment intensification with a platinum doublet. So the approach essentially was to reduce the chemotherapy exposure in patients who respond to immunotherapy. And only about 17.5% of the patients on the trial received chemotherapy based on lack of molecular response. So, in this trial, what they found was patients with the cfDNA response had a markedly improved PFS of 16.4 months versus 4.8 months. So essentially, like, this is a really nice study to set a foundation on which we have to do larger studies to incorporate molecular markers trying to look at cfDNA response to inform treatment strategy, either escalation or de-escalation strategies. So, I thought it was a very interesting study. Dr. Nate Pennell: Yeah. I mean, we always have this question for patients, “Should they get immunotherapy alone or combined with chemo?” and I think this certainly is intriguing, suggesting that there may be ways you can monitor people and perhaps rescue those that aren't going to respond to single agent. I'd like to see a randomized trial against, you know, this strategy, perhaps against everyone getting, say, chemoimmunotherapy or make sure that you're not potentially harming people by doing this strategy. But I agree, it's time to move beyond just observing that cell-free DNA is prognostic and important and start using it to actually guide treatment. Dr. Vamsi Velcheti: Yeah, and I would just caution though, like, you know, I think we need more data, but, however, it's certainly a very interesting piece of data to kind of help inform future trials. So, there was another abstract that caught my attention, and I think this would be a very interesting abstract in the EGFR space. Abstract 8506, "Patritumab Deruxtecan (HER3-DXd) in Resistant EGFR-Mutant Advanced Non-Small Cell Lung Cancer Patients After Third-Generation EGFR TKI," it's the HERTHENA-Lung02 study. What do you think about the results of this study? Dr. Nate Pennell: Yeah, this was, I would say, very widely anticipated and ultimately a little disappointing, despite being a positive trial. So, these are patients with EGFR-mutant non-small cell lung cancer who have progressed after a third-generation EGFR TKI like osimertinib. This is really an area of major unmet need. We do have drugs like amivantamab in this space, but still definitely an area where essentially patients move from having a highly effective oral therapy to being in the realm of chemotherapy as their best option. So, this HER3 antibody-drug conjugate, patritumab deruxtecan, had some good single-arm data for this. And we're sort of hoping this would become an available option for patients. This trial was designed against platinum-doublet chemotherapy in this setting and with a primary endpoint of progression-free survival. And it actually was positive for improved progression-free survival compared to chemo with a hazard ratio of 0.77. But when you look at the medians, you can see that the median PFS was only 5.8 versus 5.4 months. It was really a modest difference between the two arms. And on the interim analysis, it appeared that there will not be a difference in overall survival between the two arms. In fact, the hazard ratio at the interim analysis was 0.98 for the two arms. So based on this, unfortunately, the company that developed the HER3-DXd has withdrawn their application to the FDA for approval of the drug, anticipating that they probably wouldn't get past approval without that overall survival endpoint. So, unfortunately, probably not, at least for the near future, going to be a new option for these patients. Dr. Vamsi Velcheti: Yeah, I think this is a space that's clearly an unmet need, and this was a big disappointment, I should say. I think all of us were going into the meeting anticipating some change in the standard of care here. Dr. Nate Pennell: Yeah, I agree. It was something that I was telling patients, honestly, that I was expecting this to be coming, and so now, definitely a bit of a disappointment. But it happens and, hopefully, it will still find perhaps a role or other drugs with a similar target. Certainly an active area. Well, let's leave the EGFR-mutant space and move into small cell. There were a couple of very impactful studies. And one of them was Abstract 8006, “Lurbinectedin Plus Atezolizumab as First-Line Maintenance Treatment in Patients With Extensive-Stage Small Cell Lung Cancer, Primary Results from the Phase III IMforte Trial.” So, what was your impression of this? Dr. Vamsi Velcheti: Yeah, I think this is definitely an interesting study, and small cell, I remember those days when we had barely any studies of small cell at ASCO, and now we have a lot of exciting developments in the small cell space. It's really good to see. The IMforte trial is essentially like a maintenance lurbinectedin trial with atezolizumab maintenance. And the study was a positive trial. The primary endpoint was a PFS, and the study showed improvement in both PFS and OS with the addition of lurbinectedin to atezolizumab maintenance. And definitely, it's a positive trial, met its primary endpoint, but I always am a little skeptical of adding maintenance cytotoxic therapies here in this setting. In my practice, and I'd like to hear your opinion, Nate, most patients with small cell after 4 cycles of a platinum doublet, they're kind of really beaten up. Adding more cytotoxic therapy in the maintenance space is going to be tough, I think, for a lot of patients. But also, most importantly, I think this rapidly evolving landscape for patients with small cell lung cancer with multiple new, exciting agents, actually like some FDA-approved like tarlatamab, also like a lot of these emerging therapeutics like I-DXd and other ADCs in this space. You kind of wonder, is it really optimal strategy to bring on like another cytotoxic agent right after induction chemotherapy, or do you kind of delay that? Or maybe have like a different strategy in terms of maintenance. I know that the tarlatamab maintenance trial is probably going to read out at some point too. I think it's a little challenging. The hazard ratio is also 0.73. As I said, it's a positive trial, but it's just incremental benefit of adding lurbi. And also on the trial, we need to also pay attention to the post-progression second-line treatments, number of patients who received tarlatamab or any other investigational agents. So I think it's a lot of questions still. I'm not quite sure I'd be able to embrace this completely. I think a vast majority of my patients might not be eligible anyway for cytotoxic chemotherapy maintenance right away, but yeah, it's tough. Dr. Nate Pennell: Yeah. I would call this a single and not a home run. It definitely is real. It was a real overall survival benefit. Certainly not surprising that a maintenance therapy would improve progression-free survival. We've known that for a long time in small cell, but first to really show an overall survival benefit. But I completely agree with you. I mean, many people are not going to want to continue further cytotoxics after 4 cycles of platinum-doublet chemo. So I would say, for those that are young and healthy and fly through chemo without a lot of toxicity, I think certainly something worth mentioning. The problem with small cell, of course, is that so many people get sick so quickly while on that observation period after first-line chemo that they don't make it to second-line treatment. And so, giving everyone maintenance therapy essentially ensures everyone gets that second-line treatment. But they also lose that potentially precious few months where they feel good and normal and are able to be off of treatment. So, I would say this is something where we're really going to have to kind of sit and have that shared decision-making visit with patients and decide what's meaningful to them. Dr. Vamsi Velcheti: Yeah, I agree. The next abstract that was a Late-Breaking Abstract, 8000, “Overall Survival of Neoadjuvant Nivolumab Plus Chemotherapy in Patients With Resectable Non-Small Cell Lung Cancer in CheckMate-816.” This was a highly anticipated read-out of the OS data from 816. What did you make of this abstract? Dr. Nate Pennell: Yeah, I thought this was great. Of course, CheckMate-816 changed practice a number of years ago when it first reported out. So, this was the first of the neoadjuvant or perioperative chemoimmunotherapy studies in resectable non-small cell lung cancer. So, just to review, this was a phase 3 study for patients with what we would now consider stage II or stage IIIA resectable non-small cell lung cancer. And they received three cycles of either chemotherapy or chemotherapy plus nivolumab, and that was it. That was the whole treatment. No adjuvant treatment was given afterwards. They went to resection. And patients who received the chemoimmunotherapy had a much higher pathologic complete response rate and a much better event-free survival. And based on this, this regimen was approved and, I think, at least in the United States, widely adopted. Now, since the first presentation of CheckMate 816, there have been a number of perioperative studies that have included an adjuvant component of immunotherapy – KEYNOTE-671, the AEGEAN study – and these also have shown improved outcomes. The KEYNOTE study with pembrolizumab also with an overall survival benefit. And I think people forgot a little bit about CheckMate-816. So, this was the 5-year overall survival final analysis. And it did show a statistically and, I think, clinically meaningful difference in overall survival with the 3 cycles of neoadjuvant chemo-nivo compared to chemo with a hazard ratio of 0.72. The 5-year overall survival of 65% in the chemo-IO group versus 55% with the chemo alone. So a meaningful improvement. And interestingly, that hazard ratio of 0.72 is very similar to what was seen in the peri-operative pembro study that included the adjuvant component. So, very much still relevant for people who think that perhaps the value of those neoadjuvant treatments might be really where most of the impact comes from this type of approach. They also gave us an update on those with pathologic complete response, showing really astronomically good outcomes. If you have a pathologic complete response, which was more than a quarter of patients, the long-term survival was just phenomenal. I mean, 95% alive at 5 years if they were in that group and suggesting that in those patients at least, the adjuvant treatment may not be all that important. So, I think this was an exciting update and still leaves very much the open question about the importance of continuing immunotherapy after surgery after the neoadjuvant component. Dr. Vamsi Velcheti: Yeah, I completely agree, Nate. I think the million-dollar question is: “Is there like a population of patients who don't have complete response but like maybe close to complete response?” So, would you like still consider stopping adjuvant IO? I probably would not be comfortable, but I think sometimes, you know, we all have patients who are like very apprehensive of continuing treatments. So, I think that we really need more studies, especially for those patients who don't achieve a complete CR. I think trying to find strategies for like de-escalation based on MRD or other risk factors. But we need more trials in that space to inform not just de-escalation, but there are some patients who don't respond at all to a neoadjuvant IO. So, there may be an opportunity for escalating adjuvant therapies. So, it is an interesting space to watch out for. Dr. Nate Pennell: No, absolutely. Moving to KRAS-mutant space, so our very common situation in patients with non-small cell lung cancer, we had the results of Abstract 8500, “First-Line Adagrasib With Pembrolizumab in Patients With Advanced or Metastatic KRASG12C-Mutated Non-Small Cell Lung Cancer” from the phase 2 portion of the KRYSTAL-7 study. Why was this an interesting and important study? Dr. Vamsi Velcheti: First of all, there were attempts to kind of combine KRASG12C inhibitors in the past with immune checkpoint inhibitors, notably sotorasib with pembrolizumab. Unfortunately, those trials have led to like a lot of toxicity, with increased especially liver toxicity, which was a major issue. This is a phase 2 study of adagrasib in combination with pembrolizumab, and this is a study in the frontline setting in patients with the G12C-mutant metastatic non-small cell lung cancer. And across all the PD-L1 groups, the ORR was 44%, and the median PFS was 11 months, comparable to the previous data that we have seen with adagrasib in this setting. So it's not like a major improvement in clinical efficacy. However, I think the toxicity profile that we were seeing was slightly better than the previous trials in combination with sotorasib, but you still have a fair amount of transaminitis even in the study. At this point, this is not ready for clinical primetime. I don't think we should be using sotorasib or adagrasib in the frontline or even in the second line in combination with checkpoint inhibitors. Combining these drugs with checkpoint inhibitors in the clinical practice might lead to adverse outcomes. So, we need to wait for more data like newer-generation G12C inhibitors which are also being studied in combination, so we'll have to kind of wait for more data to emerge in this space. Dr. Nate Pennell: I agree, this is not immediately practice changing. This is really an attempt to try to combine targeted treatment with immune checkpoint inhibitor. And I agree with you that, you know, it does appear to be perhaps a little bit better tolerated than some of the prior combinations that have tried in this space. The outcomes overall were not that impressive, although in the PD-L1 greater than 50%, it did have a better response rate perhaps than you would expect with either drug alone. And I do think that the company is focusing on that population for a future randomized trial, which certainly would inform this question better. But in the meantime, I agree with you, there's a lot of newer drugs that are coming along that potentially may be more active and better tolerated. And so, I'd say for now, interesting but we'll wait and see. Dr. Vamsi Velcheti: Yeah, so now moving back again to small cell. So, there was a Late-Breaking Abstract, 8008. This is a study of tarlatamab versus chemotherapy as second-line treatment for small cell lung cancer. They presented the primary analysis of the phase III DeLLphi-304 study. What do you think about this? Dr. Nate Pennell: Yeah, I thought this was really exciting. This was, I would say, perhaps the most important lung study that was presented. Tarlatamab is, of course, the anti-DLL3 bispecific T-cell engager compound, which is already FDA approved based on a prior single-arm phase II study, which showed a very nice response rate as a single agent in previously treated small cell lung cancer and relatively manageable side effects, although somewhat unique to solid tumor docs in the use of these bispecific drugs in things like cytokine release syndrome and ICANS, the neurologic toxicities. So, this trial was important because tarlatamab was approved, but there were also other chemotherapy drugs approved in the previously treated space. And so, this was a head-to-head second-line competition comparison between tarlatamab and either topotecan, lurbinectedin, or amrubicin in previously treated small cell patients with a primary endpoint of overall survival. So, a very well-designed trial. And it did show, I think, a very impressive improvement in overall survival with a median overall survival in the tarlatamab group of 13.6 months compared to 8.3 months with chemotherapy, hazard ratio of 0.6. And progression-free survival was also longer at 4.2 months versus 3.2 months, hazard ratio of 0.72. In addition to showing improvements in cancer-related symptoms that were improved in tarlatamab compared to chemotherapy, there was actually also significantly lower rates of serious treatment-related adverse events with tarlatamab compared to chemotherapy. So, you do still see the cytokine release syndrome, which is seen in most people but is manageable because these patients are admitted to the hospital for the first two cycles, as well as a significant number of patients with neurologic side effects, the so-called ICANS, which also can be treated with steroids. And so, I think based upon the very significant improvement in outcomes, I would expect that this should become our kind of standard second-line treatment since it seems to be much better than chemo. However, tarlatamab is definitely a new drug that a lot of places are not used to using, and I think a lot of cancer centers, especially ones that aren't tied to a hospital, may have questions about how to deal with the CRS. So, I'm curious your thoughts on that. Dr. Vamsi Velcheti: Yeah, thank you, Nate. And I completely agree. I think the data looked really promising, and I've already been using tarlatamab in the second-line space. The durability of response and overall, having used tarlatamab quite a bit - like, I participated in some of the early trials and also used it as standard of care - tarlatamab has unique challenges in terms of like need for hospitalization for monitoring for the first few treatments and make sure, you know, we monitor those patients for CRS and ICANS. But once you get past that initial administration and monitoring of CRS, these patients have a much better quality of life, they're off chemotherapy, and I think it's really about the logistics of actually administering tarlatamab and coordination with the hospital and administration in the outpatient setting. It's definitely challenging, but I think it definitely can be done and should be done given what we are seeing in terms of clinical efficacy here. Dr. Nate Pennell: I agree. I think hospital systems now are just going to have to find a way to be able to get this on formulary and use it because it clearly seems to be more effective and generally better tolerated by patients. So, should move forward, I think. Finally, there's an abstract I wanted to ask you about, Abstract 8001, which is the “Neoadjuvant osimertinib with or without chemotherapy versus chemotherapy alone in resectable epidermal growth factor receptor-mutated non-small cell lung cancer: The NeoADAURA Study”. And this is one that I think was also fairly highly anticipated. So, what are your thoughts? Dr. Vamsi Velcheti: You know, I wasn't probably surprised with the results, and I believe we were all expecting a positive trial, and we certainly were handed a positive trial here. It's a phase III trial of osimertinib and chemotherapy or osimertinib in the neoadjuvant space followed by surgery, followed by osimertinib. It's a global phase 3 trial and very well conducted, and patients with stage II to stage IIIB were enrolled in the study. And in the trial, patients who had a neoadjuvant osimertinib with or without chemotherapy showed a significant improvement in major pathologic response rates over chemotherapy alone. And the EFS was also positive for osimertinib and chemotherapy, osimertinib monotherapy as well compared to chemotherapy alone. So overall, the study met its primary endpoint, and I think it sheds light on how we manage our patients with early-stage lung cancer. I think osimertinib, we know that osimertinib is already FDA approved in the adjuvant space, but what we didn't really know is how was osimertinib going to work in the neoadjuvant space. And there are always situations, especially for stage III patients, where we are on the fence about, are these patients already close to being metastatic? They have, like, almost all these patients have micrometastatic disease, even if they have stage III. As we saw in the LAURA data, when you look at the control arm, it was like a very short PFS. Chemoradiation does nothing for those patients, and I think these patients have systemic mets, either gross or micrometastatic disease at onset. So, it's really important to incorporate osimertinib early in the treatment course. And I think, especially for the locally advanced patients, I think it's even more important to kind of incorporate osimertinib in the neoadjuvant space and get effective local control with surgery and treat them with adjuvant. I'm curious to hear your thoughts, Nate. Dr. Nate Pennell: I am a believer and have long been a believer in targeted adjuvant treatments, and, you know, it has always bothered me somewhat that we're using our far and away most effective systemic therapy; we wait until after they go through all their pre-op treatments, they go through surgery, then they go through chemotherapy, and then finally months later, they get their osimertinib, and it still clearly improves survival in the adjuvant setting. Why not just start the osimertinib as soon as you know that the patient has EGFR-mutant non-small cell lung cancer, and then you can move on to surgery and adjuvant treatment afterwards? And I think what was remarkable about this study is that all of these patients almost - 90% in each arm - went to surgery. So, you weren't harming them with the neoadjuvant treatment. And clearly better major pathologic response, nodal downstaging, event-free survival was better. But I don't know that this trial is ever going to show an overall survival difference between neoadjuvant versus just surgery and adjuvant treatment, given how effective the drug is in the adjuvant setting. Nonetheless, I think the data is compelling enough to consider this, certainly for our N2-positive, stage IIIA patients or a IIIB who might be otherwise surgical candidates. I think based on this, I would certainly consider that. Dr. Vamsi Velcheti: Yeah, and especially for EGFR, like even for stage IIIB patients, in the light of the LAURA study, those patients who do not do too well with chemoradiation. So you're kind of delaying effective systemic therapy, as you said, waiting for the chemoradiation to finish. So I think probably time to revisit how we kind of manage these locally advanced EGFR patients. Dr. Nate Pennell: Yep, I agree.

Piše Tatjana Pregl Kobe, bere Lidija Hartman. Eden od načinov približevanja motivni izpovedi enega najžlahtnejših likovnih umetnikov prejšnjega stoletja, Vladimirja Makuca, je bil od nekdaj poetičnost. V desetletjih je intimna melodioznost v vseh oblikah njegovega likovnega ustvarjanja postala zaščitni znak minucioznega in na neki način sentimentalnega umetnika, ki ga je sprejela tako strokovna kot široka javnost. Ni presenetljivo, da so ob njegovih delih sočasno nastajale obsežnejše lirske izpovedi vidnih slovenskih poetov, kot so Ciril Zlobec, Tone Pavček in Ivo Svetina, ki so ob njegovih delih opevali Kras in slovensko primorje ter v verze prevajali svoj pogled na intimnost njegovih likovnih sporočil. Meje novega navdiha je Makuc zaslutil na prelomu tistega obdobja, ko je bil prvi zanosni melodični spev Krasu izpet in je zavestno prestopil v svet tehničnega izobilja, v sodobne, iz vedno novih tehnicističnih spoznanj skovane sanje. A nikoli, v nobenem trenutku ni kot interpret Krasa in mediteranskega duha pretrgal vezi s kraji, iz katerih je izhajal. Ob letošnji spominski razstavi z naslovom Želja po nebu v kranjski Galeriji Prešernovih nagrajencev je bila k sodelovanju povabljena pesnica Miljana Cunta. Ne zato, ker je bila lani dobitnica nagrade Prešernovega sklada, temveč predvsem kot njegova rojakinja. Naslov dvojezične knjige Pogovori z Vladimirjem Makucem / Conversazioni con Vladimir Makuc nedvoumno sporoča, da gre za pesničin dvogovor s slikarjevimi deli, pozorno branje pa razgrinja, da gre za projekcijo pesničinega doživljanja Makučevih umetnin, njenega intimnega poglabljanja vanje, a tudi za razmišljanje o mukah in radostih ustvarjanja v vseh umetniških zvrsteh. Svojo značilno likovno govorico, ki se je mojstrsko približevala otroški risbi, je Makuc organsko prelival med grafiko, slikarstvom in kiparstvom. Kako je pesnica vodila pogovor z izjemnim likovnikom, ki je brezhibno obvladoval metier prisluškujoč pticam, zemlji in imaginarnemu domu svoje ustvarjalne domišljije, sporoča že v prvih stavkih uvoda. Šla je za umetnikovimi podobami, kot se človek spusti do kletnih prostorov, da bi videl, ali so morda povezani s kletnimi prostori sosednje hiše. Nato je obiskala kraje njegovega bivanja in delovanja, premišljevala o umetnikovi potrebi po samoti, vstopila v cerkvico na hribu, kjer je več let kopiral mojstrovine iz preteklosti, s čimer si je tlakoval lastno pot, zaznala slikarjevo otroško zaljubljenost v lepoto in njegovo trmasto zazrtost vase. Ko je zbrala vtise, se je v večerni tišini vprašala, katere njegovih podob so se vtisnile vanjo, in si priklicala v zavest lastne spomine, slutnje, sanje. Stalnice v lirskem jeziku Miljane Cunta so slogovna jasnost, čistost in milina, skrben izbor prispodob, pretanjeno občutje presojne lepote ter prečiščena, a zato nič manj bogata lirska izreka besed. Že v njenem pesniškem prvencu Za pol neba, v katerem je s prefinjeno krhkostjo upesnjevala pokrajine hrepenenja in presojnost ženske lepote, se nežno razpirajo metafore poetičnega. V knjigi Svetloba od zunaj se je v petih ciklih z opisi usodnih in neopaznih vsakdanjih dogodkov vrnila k poetiki prvenca s skrajno občutenim, duhovno povzdignjenim, domala eteričnim jezikom. S pesniško zbirko Nekajkrat smo zašli, zdaj se vračamo se pesnica premika po času in prostoru natančno, premišljeno, skoraj asketsko, a hkrati gibko, lahkotno in jasno zaznava podobe in jih zapisuje v večnost. Zbirka Pesmi dneva pa skupaj s črno-belimi fotografijami nenavadnih prizorov navadnih stvari Dušana Šarotarja predstavlja drugačno konceptualno zasnovo. Pesmi v prozi, ki prinašajo célo vesolje enega dneva, v katerem se prelivajo navzočnost in odsotnost, tišina in živost, počitek in premišljevanje, v zasnovi spominjajo na Pogovore z Vladimirjem Makucem. Za pogovore, ki so – ob osmih dvostranskih in šestintridesetih enostranskih reprodukcijah likovnih del Vladimirja Makuca – za pesnico v tej poetični knjigi dokument osebnega potovanja v prostoru in času, je bil primeren drugačen žanr. Pesniška zasnova knjige – skupaj z uvodno stranjo – temelji na dvajsetih obsežnih fragmentih, zapisanih kot kratke ali daljše zgodbe, ki koncizno grajene ena za drugo kažejo na pripovedno širino, s katero pesnica pritegne v razmislek širok nabor tém, asociiranih z Makučevimi vizualnimi podobami. Glede na vprašanje, kako tènka je meja med klasično zapisano kratko zgodbo in poetično zapisanim kratkim proznim besedilom, ni dvoma, da gre v knjigi kljub stvarnemu naslovu, ki je morda prav zaradi tega zavajajoč, za čisto poezijo. Avtoportret oziroma portret – tako pesnice kot za v pogovoru z njo živo navzočega umetnika v tej knjigi – se kaže kot nikoli dokončana pesem. Kljub temu je nujno, da zdaj v tihoti ateljeja najdeš tistega, ki zre v vsa zrcala sveta in ostane cel. Vladimir Makuc se je zavedal notranjih omejitev svobode in jih je zato likovno lucidno izpovedoval. Ptice, voli, krogi – kot zobati urni mehanizmi ali planeti – in znaki, ki jim morda še sam ni razvozlal pomena, so ga tako zasvojili, da je kot mistik in vizionar čutil njihovo moč. Pod črepinjasto suhoto se udira korak, vse globlje stopa, zamotan in težak, dokler se v nekem hipu – kdo ga je priklical? – ne zasveti zlata sled. V svojem zadnjem obdobju je Makuc – v slikah na platnu, grafikah, na akvarelih, miniaturnih kipih in na kamnitih skulpturah, posejanih z zelenimi, a ošiljenimi črepinjami – osvobodil črto, da je spregovorila z lastnim pomenom in ptice odrešil znakovne funkcionalnosti, da so se polne prhutave radoživosti, zvedave, a prestrašene v prostorih, nasičenih s črtami, osvobajale. V zadnjem zapisu Miljana Cunta suvereno, nič kaj sramežljivo nagovori slikarja z besedami »Dragi prijatelj, naj ti predstavim svoj atelje. Nič posebnega – miza, stol in nekaj knjig v kotu spalnice.« Celostranski zapis spremlja črno-bela fotografija iz Makučevega ateljeja, na kateri je Lado Mlekuž ujel umetnika med pripravo za tisk grafike na njegovi mizi. Zdi se, kot bi prisluhnil pesničinim besedam, ki zaključujejo knjigo: »Tako se zlagajo pesmi, prijatelj, v ateljejih večnosti, kot mize – ena v drugi prebivajo, naključne sopotnice, da te spominjajo.«

A Position Paper on ctDNA Testing in Clinical Trials

JCO PO author Dr. Philip Philip at Henry Ford Cancer Institute and Wayne State University shares insights into his JCO PO article, “Incorporating Circulating Tumor DNA Testing Into Clinical Trials: A Position Paper by the National Cancer Institute GI Oncology Circulating Tumor DNA Working Group.” Host Dr. Rafeh Naqash and Dr. Philip discuss how prospective trials are required to clarify the role of ctDNA as a valid surrogate end point for progression-free or overall survival in GI cancers. Transcript Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations, where we bring you engaging conversations with authors of clinically relevant and highly significant JCO PO articles. I'm your host, Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Assistant Professor at the OU Health Stephenson Cancer Center at the University of Oklahoma. Today, we are excited to be joined by Dr. Philip Philip, Chair of Hematology and Oncology, as well as leader of GI and Neuroendocrine Oncology. He's also the Professor of Oncology and Pharmacology, as well as Co-Leader of the Pancreatic Cancer Program and Medical Director of the Cancer Clinical Trial and Translational Research Office at the Henry Ford Cancer Institute at Wayne State University. Dr. Philip is also the Senior Corresponding Author of the JCO Precision Oncology article entitled, "Incorporating Circulating Tumor DNA Testing into Clinical Trials: A Position Paper by the National Cancer Institute GI Oncology Circulating Tumor DNA Working Group." At the time of this recording, our guest's disclosures will be linked in the transcript. Dr. Philip, welcome to our podcast, and thank you so much for joining us today. Dr. Philip Philip: Thank you so much, Dr. Naqash, for providing me this opportunity to be discussing this with you. Dr. Rafeh Naqash: This is a very timely and interesting topic. We've done a couple of podcasts on ctDNA before, but none that is an opinion piece or a guidance piece based on what you guys have done. Could you tell us what led to this perspective piece or guidance manuscript being published? There is some background to this. Could you tell us, for the sake of our listeners, what was the initial thought process of why you all wanted to do this? Dr. Philip Philip: The major reason for this was the fact that investigators were considering using ctDNA as a primary endpoint in clinical trials. Obviously, you hear my focus will be on gastrointestinal cancers. So, the idea was, can we use ctDNA instead of using the traditional endpoints such as disease-free survival, progression-free survival, or overall survival? And the question was, do we have enough data to support that in patients with gastrointestinal cancers? Now, the article obviously goes over some review of the data available, but the core of the article was not to do a comprehensive review of ctDNA use and the evidence so far, although we used that in really putting our recommendations. So, we really had to evaluate available data. But the focus was, what are the gaps? What do we need to do? And are we ready to use ctDNA as a primary endpoint in clinical trials? Dr. Rafeh Naqash: Thank you for giving us that background. Obviously, a very broad, complicated topic with a bunch of emerging data that you've highlighted. But most importantly, for the sake of, again, trainees and listeners, could you help us understand the difference between tumor-informed and non-tumor-based ctDNA assessments? Dr. Philip Philip: Sure. So, the tumor-informed is simply meaning that you're taking the genomic makeup or the DNA fingerprint of the cancer in a given patient, and you create a profile, and then use that profile to see whether that DNA is present in the blood. So, it's very simple. It's like barcoding DNA and then going and looking for it in the blood, which means that you have to have the primary tumor. When I say primary tumor, you need to have the tumor to start off with. It doesn't really apply, maybe easily, if you just have a fine-needle aspirate and things like that. So, you really have to have a good amount of the tumor for you to be able to do that. So, that's a tumor-informed, and from the name, you can easily understand how it's done, compared to the other one, which is uninformed, whereby off-the-shelf probes are used to look for tumor DNA. And again, they're based on prior experience and prior identification of the key DNA changes that will be seen in tumors. So, that's the difference between the two in terms of the principle of the test. The uninformed will not require you to send the original tumor that you're trying to test. However, the informed, you do. The turnaround time is, again, a bit different because, as you would expect, it's shorter in the uninformed. And the reason for that, again, is the initial preparation of the profile that is going to be used in the future when you do serial testing. The sensitivity has been a bit of a discussion. Initially, people have thought that tumor-informed assays are more sensitive, more specific, more sensitive, et cetera. But in our review, we come to the conclusion saying that we don't think that's going to be a major difference. And there are obviously improvements happening in both types of assays. The sensitivities have been improving. So, at this point in time, we do feel that you have two types of assays, and we didn't feel strongly about recommending one over the other. Dr. Rafeh Naqash: Thank you for that description. You mentioned something about sensitivity, specificity. Obviously, many of us who have ordered both tumor-informed and tumor-uninformed, we understand the differences with respect to the timing. The tumor-informed one can take more time. The uninformed one, being a sort of a liquid biopsy, may not necessarily have as much of a turnaround time. Could you briefly speak to those limitations or advantages in the context of the two versions? Dr. Philip Philip: I just really want to also highlight that when we say turnaround time, so for the tumor-informed assays, the first assay that we do will be requiring a turnaround time. But once the pattern has been set and the profile has been documented, the subsequent testing doesn't require much in the way of waiting. However, when you're using this for the minimal residual disease, then you have a window of opportunity to work at. That's number one. So, it means that in patients who have resected cancer, you may end up having to wait longer than the tumor-uninformed assay, especially if you don't have easy access to your material for the baseline material to send. And also, what we'd like to do is not do the test immediately after the operation or soon after the operation. Give it some time. There's a window where you can work at, and starting minimally two weeks after the surgery. But in my experience, I'd like to wait at least four weeks just to make sure that we got an accurate reading. Sometimes when you do it very early after surgery, because of the effect of the surgery and the release of the normal DNA is also, it may dilute the tumor DNA, and then you may get a false negative. So, basically, it depends on the clinical situation. And your question is, is one better to be used than the other? I think ultimately, it ends up with the turnaround time not being as much of an issue. It might be in certain situations, depending on when you see the patients after the operation or any definitive treatment you've done and you want to look for minimal residual disease. But in general, I don't think that's going to be a real major issue. Dr. Rafeh Naqash: I remember discussing this with one of the tumor-informed platforms with regards to this barcode you mentioned. They generate a fingerprint of sorts for the tumor on the tissue, then they map it out in the blood and try to assess it longitudinally. And one of the questions and discussions we had was around the fact that most of the time, these barcoded genes are not the driver genes. If you have a KRAS mutant tumor, it's not going to be the KRAS gene that they map out. It's something that is specific. So, is there a possibility that when you are mapping out, let's say, a metastatic tumor where there is truncal and subclonal mutations at different sites, that you capture something that is not necessarily truncal, and that does not necessarily reflect some other metastatic site having a recurrence? So basically, over time, you don't see a specific mutational pattern or the signature on the tumor-informed, and then you see something on the scan which makes you think, "Well, it was not the right test," but actually it could be a different subclone or a clone mutation at a different site. Is there a concept that could help us understand that better? Dr. Philip Philip: I think you raise a very important point. Although, I have to say from my practical experience, that is not a common thing to see. In fact, for some reason, we don't see it that often in any frequency that should, at this point in time, make us concerned about the serial testing. But what you were mentioning is a real challenge which can happen. Now, the question is, how often does the clonal evolution or the divergence happen to the point that it's going to be like a false negative, is what you're saying. At this point in time, we don't really have good information on that, or any good information, practical information. And when we went through the literature and we were looking for the evidence, that wasn't something which was there clearly telling us. Although, this is something that has to be studied further prospectively. And I don't know of a study, but I might be missing it, I don't know of a study which is systematically looking at this. Although it's a very valid hypothesis and theoretical basis for it, but in real life, we still have to see how much does it really interfere with the validity of this kind of testing. Dr. Rafeh Naqash: Which brings us to the more important discussion around your manuscript. And I think that the overarching theme here is the consensus panel that you guys had recommended that ctDNA-based metrics be used as a co-primary endpoint. Could you tell us, for early-phase trials, maybe phase two studies for that matter, could you tell us what were some of the aspects that led to this consensus being formed from your working group? Dr. Philip Philip: Well, there were a number of reasons, in any order of priority, but one of them is we don't have a good sense of dynamics of the ctDNA. And again, remember this article was about gastrointestinal cancers. Maybe we know more about colon cancer, but, or colorectal cancer, but we don't know that well about the upper GI, like gastroesophageal, pancreatic, et cetera. So, we don't know what is the false negative percentages. And in fact, we know that there are certain sites of the disease, metastases, that do not lead to enough shedding of the DNA into the circulation. So, that was something else. I mean, false negativity, not knowing exactly what the dynamics are, especially in different disease types. So, that was another reason, which we felt that it may not be at this time primetime to really have those ctDNA tests as a primary endpoint. We wanted to make sure that, on the other hand, we wanted to make sure that people consider including ctDNA more like a secondary endpoint so that we can gain the information that we're lacking, at least the ones I mentioned to you. So, that was an important point of our discussions and deliberations when we were writing the article. Dr. Rafeh Naqash: And I myself have been on both sides of the aisle where - I treat people with lung cancer, you mentioned appropriately that most of the data that we have for ctDNA is generated from GI cancers, especially colorectal - on the lung cancer side, I myself had a patient with an early-stage cancer, had treatment, surgery, immunotherapy, and then had ctDNA that was tumor-informed, was positive four to five months before the imaging actually showed up. And on the other side, I've also had an individual where early-stage lung cancer, surgery, immunotherapy, and then had PET scans that showed a positive finding, but the ctDNA, tumor-informed ctDNA, was negative multiple times. So, I've seen both aspects of it, and your paper tries to address some of these questions on how to approach a negative, radiologically negative imaging but positive ctDNA potentially, and vice versa. Could you elaborate upon that a little bit? Dr. Philip Philip: Well, obviously, we do see this in practice. Again, I do GI oncology. I have patients who, you do ctDNA. I mean, my advice to anyone, when you order a test, you have to make sure that you know what you're going to do with the test, because that's the most important thing. You get a positive test, you do something. You get a negative test, you do something. But most importantly, our patients who you're following up, they are very anxious for a diagnosis they have that is not- I mean, it's cancer. If you're doing these tests, if we get continuous, repeatedly negative testing, then you really have to also tell the patient that there's a false negativity. And I mentioned to you earlier, there are certain sites of disease, like peritoneal, they may not be producing enough, or there are some tumors, their biology is such that they don't release as much to be detected in the blood. Now, one day we will get maybe a more sensitive test, but I'm talking about the tests we have now. On the other hand, if you get a positive testing, you have to make a distinction for ctDNA in the minimal residual disease situation. If you get a positive test, there is enough evidence that the patient has a worse prognosis. There's evidence for that. No one can dispute that. Again, I'm talking about colorectal cancer where there are a lot of data for that. So, in that situation, there are studies that are looking, if you get a positive test in someone who you're not intending to give any adjuvant treatment, there are studies looking into that, both in terms of intensifying, like chemotherapy, in certain patients. And also, there's work being done, if you have a negative test in someone who has stage III disease, for example, or definitely stage II disease, they may not need to give them chemo. Those things are happening. But in metastatic disease, it's a different situation. Or even in someone who has received surgery, adjuvant chemotherapy, in those patients where they, whether they're now under, in the surveillance mode, those patients, if you have a positive, it may be positive. I had a recent patient like those, eight months before we saw anything on the scans. So, the question is, if you have a positive test, is there any advantage in giving them treatment, systemic treatment? Of course, we're assuming that the PET scan is negative. So, is there really any advantage in giving someone treatment ahead of time, before you see the imaging changes? That kind of data, in my opinion, is not really available or strong. You can always think of it in different ways, explain it in different ways. It's minimal disease, maybe you get a better response. But I don't know if we really can justify at this time. Therefore, in my practice, my own practice, I do not treat just a positive ctDNA. Again, that's different than after surgery when you're thinking of whether to give adjuvant treatment, no adjuvant treatment. But someone who's finished treatments and then you're just serially monitoring the disease, those patients, I do not treat them with chemotherapy. And that was something which, based on the literature we reviewed, there was nothing out there to definitely- I mean, if you see something positive, you will do a scan earlier, you will talk to the patient, examine the patient, whatever. But if there's nothing there, starting a treatment, that's not justified at this point in time. Now, you need to do a study like that. Definitely, you need to do a study. But I can tell you that from my experience, having been involved with study design and all that, it's not an easy trial to do. It's going to be a trial- at a minimum, it will take many patients, it will take longer time to complete, and there are a number of variables there. If someone is willing to put a lot of money into it, it can be done. But I can tell you that that kind of intention to do a study like that has been very much a challenge at this time. Dr. Rafeh Naqash: Of course, as you mentioned, the follow-up time that you need for a study like that is going to be very long to get to meaningful outcomes. Dr. Philip Philip: You need to be very patient to do such a study. But the problem with a very long study is that things change, standard of care changes with time, and the assays will change. So, that's why we don't have that kind of data. I'm not sure if there are people in the community or in the academic centers who do treat based on only positive ctDNA. The other thing is that you really have to always consider the psychological impact of these tests on patients and caregivers. Sometimes it can be really very stressful, burdensome to people to sit there just waiting for the disease to show up on a scan. And therefore, in my opinion, I'm not saying definitely don't use it in that situation, I'm just saying that you have to personalize it also, to see the patient who you would like to do it and then other patients who may not do it, or you think that it's not good for them to do it. And the patient also has to understand the outcome of the test and how you're going to be interpreting it. Dr. Rafeh Naqash: That's a lot of great insights, Dr. Philip, and I know you've been involved in trial designs. I'm sure NCT and cooperative groups are actively thinking and incorporating ctDNA-based metrics as one of the endpoints in their trial. I know of a GU study that's, I think it's an Alliance study, trying to de-escalate treatment based on ctDNA. I have one of my colleagues who's also a GU investigator at OU, he's doing a ctDNA-based, tumor-informed-based de-escalation. So, obviously, more and more data, hopefully, that'll be generated in the next couple of years. Dr. Philip Philip: But remember, these studies are not using it as an endpoint. They're using it as a means of optimizing treatment, which is a bit different. So, as an endpoint, can you do a phase III trial of, let's say, a thousand patients, and your primary endpoint is not survival, but you're saying, "Can I reduce the ctDNA, clear it earlier, or whatever?" That's the sort of thing this article was about. We can't do that at this time. Dr. Rafeh Naqash: I totally understand. Thank you for explaining the difference, and hopefully more to come in this space in the next couple of years. I briefly wanted to touch upon your personal career and journey based on all that you've done and accomplished. Could you tell us about how you started, what your journey has been like, and how that connects with what you're doing right now, including mentoring other trainees and junior faculty? Dr. Philip Philip: Well, when I was in high school, I wanted to be an engineer, but I grew up in Baghdad, and all my friends wanted to do medicine, so I went with the tide, so I did medicine. I don't regret that. I would do it again if I had the opportunity. The reason why I did oncology was, I left the country and did a PhD in clinical pharmacology at the University of London. And that really got me, it was a topic which included, which was on cancer. So, I really got interested in a disease that is really a lot of science, and things are new, or were new at the time. And if I want to look back what I was doing, the beginning of my training in the 80s, second half of the 80s, and now, it's unbelievable how things have changed. But one of the things which I really have to say is that almost all my life I've been in what we call academic institutions. But I firmly believe that for people, whether academic or not, you have to be a very good, astute clinician, because many of the things we do, really, we're trying to put the patients in the center. It's not only doing fancy science, it's to do things that help the patients. And you can bring in bits and pieces of fancy science or less fancy science, but that's something which is really extremely important for us to think about, being a very good clinician, very good doctor, because medicine is a science, whether you're practicing as a solo practitioner or you're part of a large academic center. It's the way you think, the way you interrogate things that you're not sure of, the way you collaborate, the way you learn every day. I mean, at my age, I still don't like to miss any tumor board, because in each tumor board, there's something you learn, even if you think that you know everything. So, that's really the whole thing of it, is that be a very good clinician, be open-minded. Always, you have to think of things that, they look interesting, they look somehow unexplained. Always try to help find the solutions and do that. One of the major things that I feel that people should do is being also very focused on things. I mean, you have to also know what you want to do in the next 5, 10, 15 years. Because although everyone is in it in the same way when we start, but there are different things that drive people, people who want to do more of the formal research, like being an academic-like institution. But there are also a lot of people who are very successful outside of a- what we call an academic setting. In the United States, most people are not working in an academic kind of setting. Although, for me, the distinction between academic and community is getting less and less, because if you think that you do phase I trials in academia only, that's not true, because there are, in fact, in the state of Michigan, the most active phase I doctor is not even in academia, he's in private practice. So, you can do all these things. It's a matter of what you like to do, and you really have to make sure you know what you want to do. Because sometimes people are, especially early on, they get a bit confused, “What I want to do.” There's an issue of doing general oncology versus subspecialist. If you're a subspecialist doing only GI, you have to make sure that you really also have some kind of recognition that you're only a GI oncologist, recognition regional, national, international, but some degree of recognition that you feel that people are coming to you for advice as a second opinion or whatever it is. But again, you have to decide what you think you want to be, how you want to be, because there's a lot of options here between community practice, academic practice, industry, and of course, there's always the administrative thing. Some people tend to be more like going into the line of being an administrator. So, there's a lot of options for you. Dr. Rafeh Naqash: Well, thank you again, Dr. Philip, for those pearls of wisdom.

Dr. John Sweetenham shares highlights from Day 3 of the 2025 ASCO Annual Meeting, including new research for the treatment of advanced renal cell carcinoma and 2 studies on novel approaches in non-small cell lung cancer. Transcript Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my takeaways on selected abstracts from Day 3 of the 2025 ASCO Annual Meeting. Today's selection features studies addressing the treatment of advanced renal cell carcinoma and 2 studies exploring novel approaches in non-small cell lung cancer. My disclosures are available in the transcript of this episode. The first abstract is number 4505. This study, led by Dr. Toni Choueiri of the Dana-Farber Cancer Institute, describes the final analysis of the CheckMate 214 trial, which compared the combination of nivolumab and ipilimumab with sunitinib for the first-line treatment of advanced renal cell carcinoma. The ipi-nivo combination is approved for the frontline treatment of intermediate and poor-risk advanced renal cell carcinoma based on the primary analysis of the CheckMate 214 trial, which demonstrated a higher response rate and longer overall survival compared with sunitinib. Today's presentation provided the final safety and efficacy results for the trial with long-term follow-up of more than 9 years. The intent-to-treat (ITT) population in this trial comprised 550 patients randomized to nivo and ipi versus 546 who received sunitinib. The final analysis showed sustained long-term benefit for the combination therapy. Patients given nivolumab plus ipi had a 29% reduction in the risk for death compared with sunitinib. For patients with intermediate or poor-risk disease, there was a 31% reduction in the risk of death. The probability of remaining in response through 8 years was more than doubled with nivolumab plus ipilimumab versus sunitinib in the ITT population at 48% versus 19%, and in the intermediate and poor-risk population at 50% versus 23%. The other important observation is that patients with favorable-risk disease appeared to have a 20% reduction in the risk for death at 9 years and more durable responses. This suggests a possible delayed benefit for ipi and nivo in this group since these differences were not seen in the earlier analysis. No new safety signals emerged with longer follow-up, and the results confirm the use of ipi and nivo as a standard front-line combination therapy in this disease. Since this combination has been in widespread use for some years, the results are not surprising although the subgroup analysis suggesting benefit in favorable-risk patients is likely to inform practice in the future. Today's second abstract is number is 8506, which was presented by Dr. Tony Mok from the Chinese University of Hong Kong, describing results from the phase 3 HERTHENA-Lung02 trial. This trial compared the antibody-drug conjugate patritumab deruxtecan with platinum-based chemotherapy in patients with EGFR-mutated advanced non-small cell lung cancer following a third-generation tyrosine kinase inhibitor (TKI). Patritumab deruxtecan, also known as HER3-DXd, comprises a fully human anti-HER3 IgG3 monoclonal antibody conjugated to a topoisomerase 1 inhibitor payload, and showed activity in a previous phase 2 trial in patients relapsing after EGFR TKI and chemotherapy. In this phase 3 study, this agent was compared with platinum-based chemotherapy in eligible patients with an EGFR-activating mutation who had previously received 1 or 2 EGFR TKIs, at least one of which was a third-generation drug, with relapse or progression after this therapy. Five hundred and eighty-six patients were enrolled, with progression-free survival as the primary endpoint. The primary analysis showed a 9-month progression-free survival of 29% for the experimental arm compared with 19% for platinum-based chemotherapy, for a hazard ratio of 0.77 and a P value of 0.011. With higher progression-free survival rates at 6 months and 12 months, HER3-DXd also had a better objective response rate (35.2% versus 25.3%) compared with platinum-based chemotherapy (PBC), and HER3-DXd also extended intracranial progression-free survival compared with PBC in patients with brain metastases, with a hazard ratio of 0.75. Grade 3 or more treatment-related adverse events occurred in 73% of patients treated with HER3-DXd and 57% of patients who received PBC. HER3-DXd had a higher rate of grade or more 3 thrombocytopenia, and drug-related interstitial lung disease occurred in 5% of patients in the HER3-DXd arm. The follow-up will need more time to mature since no overall survival data are currently available, but definitely an agent to watch with interest. Moving on to today's final abstract, 8500, was presented by Dr. Pasi Jänne from the Dana-Farber Cancer Institute, describing results from the phase 2 portion of the KRYSTAL-7 study. This study is exploring the use of a potent KRAS inhibitor, adagrasib, in combination with pembrolizumab in patients with advanced or metastatic KRASG12C- mutated non-small cell lung cancer. Adagrasib has already received accelerated approval in the U.S. for previously treated locally advanced or metastatic NSCLC with a KRASG12C mutation. A previous report from the KRYSTAL-7 study demonstrated encouraging activity in combination with pembrolizumab in the frontline setting for this patient group who also had more than 50% expression of PD-L1. The presentation today described efficacy and safety data for this drug combination across all PD-L1 expression levels. One hundred and forty-nine patients with a median age of 67 years were treated with the combination, 104 of whom had PD-L1 expression level results available, representing the so-called biomarker population in this trial. The overall response rate for the entire study population was 44%. In the biomarker population, the overall response rate ranged from 36% in those with less than 1% PD-L1 expression to 61% for those with more than 50% expression. For all patients, the median response duration was just over 26 months, and the median progression-free and overall survival rates were 11 and 18.3 months respectively. For the biomarker population, the median progression-free and overall survival were highest in those patients with more than 50% PD-L1. No new safety issues emerged from this analysis; the most frequent toxicities were nausea, diarrhea, and increases in transaminases. Immune-related toxicities included pneumonitis, hypothyroidism, and hepatitis. These are important results and the results of the phase 3 portion of KRYSTAL-7, which compares first-line therapy with adagrasib plus pembro versus pembro alone in the KRASG12C mutated/PD-L1 more than 50% group, will be informative. For those patients with lower levels of PD-L1 expression, the authors suggest that the treatment escalation may be beneficial, possibly including the addition of chemotherapy. That concludes today's report. Thanks for listening and I hope you will join me again tomorrow to hear more top takeaways from ASCO25.

Svetlana Slapšak: Kje smo?

Ocene

Piše Marija Švajncer, bereta Igor Velše in Sanja Rejc. Svetlano Slapšak, avtorico knjige z naslovom Kje smo? in podnaslovom Ljubljanski steganogram, je vznemirila legenda, po kateri naj bi Ljubljano, v rimskih časih imenovano Emona, ustanovili Jazon in Argonavti. Na ladji Argo so z zlatim runom bežali od Črnega morja po Donavi, navzgor po Savi in potem Ljubljanici. Druga pripoved pravi, da so Argonavti svojo ladjo ob Ljubljanici razstavili in jo čez slovenski Kras prenesli ali prepeljali do Jadranskega morja. Leta 1955 je slovenski matematik Ivo Lah zgodbo o Argonavtih nadgradil za ponazoritev svoje matematične formule. Do obale vodijo številne poti, zato je upošteval možnost, da je bil vsak del ladje Argo iz varnostnih razlogov prepeljan po drugi poti, kar naj bi zmedlo zasledovalce. Avtorica pojasni, kaj pomeni podnaslov knjige. Steganografija je praksa prikrivanja sporočila znotraj drugega sporočila in fizičnega predmeta; steganogram je njen proizvod. »V računalniških / elektronskih kontekstih je to računalniška datoteka, sporočilo, slika ali video, skrit znotraj druge datoteke, sporočila, slike ali videa … V zadnjih letih se v steganografiji uporablja število Lah, podatki se skrivajo v sliki.« Svetlana Slapšak je iz Lahove enačbe razbrala, da matematik v njej operira z nedeljivimi deli ladje. Njeno pozornost sta torej vzbudila nedeljivo in vizualizacija; prav z vizualizacijo je matematik ustvaril steganogram. V zvezi s tem je miturgija tisto, kar je poljubno in nedeljivo, vizualno in akustično, skratka, zgodba, ki je vselej drugačna. »Moj namen ni bil, da premagam pozabo, marveč da spomin miturgično razširim in obenem odstiram tehnike pozabe. Ključni element je tu nedeljivi del.« Svetlana Slapšak pravi, da je roman napisala kot poskus literarne verbaliziranja Lahove formule. Edini žanr, ki romanu ustreza, je menipska satira. Nastala je v poznem helenističnem obdobju in je nekakšna mešanica eseja, retorične vaje, verzov in zapleta, pravzaprav dekonstrukcija vseh teh žanrov. Ključni element je prenos oziroma potovanje. Argonavti se množijo vse do Lahovega števila, prenašajo sporočila in ostajajo nevidni. Samo poznavalci in poznavalke so tisti, ki jih opazujejo, opisujejo in opevajo. Svetlana Slapšak se prepričljivo uvršča mednje. Kot klasična filologinja, antropologinja, poliglotka, plodovita ustvarjalka, temeljita poznavalka zgodovine, umetnosti in številnih drugih področij razgrne svoje bogato znanje. Izobrazba, omika in razgledanost so zanjo vrednote; vedno znova poudarja, kako veliko veljavo imajo v človekovem življenju. V enem od zadnjih poglavij prikaže svojo življenjsko zgodbo, otroštvo in mladost v družini, ki jo ima danes za socialno okolje nižjega srednjega razreda in precej revno, vendar z zmožnostjo preživetja, izobraženo ter s smislom za humor. Piše o predanosti antični demokraciji in poskusom oživljanja prednosti te družbene ureditve. Doživela je veliko prelomnic. Zaradi kritičnih prizadevanj med študentsko stavko leta 1970 so jo politični nasprotniki napadli in ji prebili arkado. Srbska zgodovina se očitno ponavlja. Svetlana Slapšak je bila zmeraj uporniška in pokončna. Zna pa se tudi pošaliti na svoj račun, saj je kljub poudarjenemu intelektualizmu pogosto počela stvari, ki so jo zgolj zabavale in sproščale – od mode, aerobike in joge pa vse do zbiranja kuhinjskih receptov in domiselnega kuhanja. Avtoričino obsežno literarno-esejistično delo ima umetniško vrednost. Omeniti velja vidike eksofonije, se pravi vstopanja v drugi jezik in opuščanja materinščine – iz srbskega jezika v slovenski. Na koncu knjige sta namreč navedeni lektorica in korektorica, ne pa tudi prevajalka. Knjiga je napisana v slikovitem slogu, bogatem besedišču in jezikovno barvito. Posebnost je pisateljičino vživljanje v posamezne literarne like, tako zgodovinske kot mitične osebnosti, bodisi s pozitivnimi bodisi z negativnimi lastnostmi. Svetlana Slapšak je do njih prizanesljiva, se z njimi pogovarja in skuša razumeti njihova dejanja. Kot da bi bili živi, stopajo pred nas Charles Nodier, hči Vuka Karadžića, Gustav Mahler, Medeja, Prešernova Urška, prijateljice in še marsikdo, osebe, ki so tako ali drugače povezane z Ljubljano. Pisateljica kritično vrednoti zapostavljenost žensk, med vojaki pa jih na začetku omeni kar nekaj, ki so svoje ženske ljubili predano in tudi spoštljivo. Družbena kritika preteklosti in sedanjosti je pronicljiva, argumentirana in poglobljena. V knjigi so natisnjene pesmi v izvirnih jezikih, grškem, nemškem in češkem, ter prevodi, na koncu pa so dodane predstavitve, slikarske upodobitve ter fotografije zgodovinskih in miturgijskih likov. Večina prevodov v romanu je delo Božidarja in Svetlane Slapšak, odlomek iz drame Biljane Jovanović je prevedel Darinko Kores. Antropologinja razkriva etimološko ozadje ter se zaustavlja pri glasbenih in literarnih vrhuncih. Seznaniti se je mogoče tudi s simbolnim in mitološkim pomenom različnih živali – od slona, konja in miši, pa vse do krokodila in vrane. Knjiga Svetlane Slapšak Kje smo? je zakladnica novih in novih informacij, iz nje vejeta tudi posebna toplina in očaranost nad brezmejnimi možnostmi človekovega življenja: »Prenos, zmaga nad prostorom, upanje, da je možno znova sestaviti kose v ladjo, ki nas bo nosila daleč, daleč od smrti in blizu tistih, ki jih imamo radi.«

Broadcast from KSQD, Santa Cruz on 5-22-2025: Dr. Dawn explores groundbreaking cancer research using high-throughput "digital twin" analysis to reverse colon cancer cells back to normal states, identifying three master molecular switches that can induce normal cell differentiation without killing the cancer cells, thus avoiding traditional chemotherapy side effects. She discusses remarkable results from Memorial Sloan Kettering showing 80% of patients with mismatch repair deficient tumors, including all 49 rectal cancer patients, saw complete tumor disappearance after six months of dostarlimab immunotherapy, with no recurrence at five years and minimal side effects. The program covers innovative CRISPR applications, including targeting previously "undruggable" cancer mutations like KRAS and BRAF by selectively degrading mutant RNA messages while preserving healthy genes, offering unprecedented precision in cancer treatment. Dr. Dawn explains a clever immunotherapy approach that disguises tumors as pig organs using Newcastle disease virus carrying alpha-gal enzyme, tricking the immune system into mounting fierce attacks against cancer cells, showing promising results in both monkey and human trials. She describes fascinating research using cryoshocked tumor cells as Trojan horses, where liquid nitrogen-treated cancer cells carrying CRISPR gene editing tools directly seek out tumors, offering superior targeting compared to injecting CRISPR. The show reveals how cancers create protective acid walls around themselves to repel immune cells, with individual cancer cells pumping lactic acid away from the tumor center to form pH 5.3 barriers that kill attacking CD8 T cells within hours. Dr. Dawn discusses breakthrough mRNA cancer vaccines for glioblastoma using patients' own tumor cells, showing rapid immune system activation within 48 hours and extending survival in both dogs and humans with this aggressive brain cancer. She explores the "flower code" mechanism where cancer cells gaslight healthy cells through epigenetic manipulation, expressing dominant "flower win" codes to overpower normal cells expressing "flower lose" codes in biological turf wars. The program addresses systemic problems in cancer classification, explaining how organ-based categorization delays access to effective treatments, with patients waiting years for drugs that could help based on molecular profiles rather than tumor location. Dr. Dawn concludes by highlighting medical discrimination against people with Duffy null phenotype, primarily affecting African Americans, whose naturally lower neutrophil counts lead to reduced chemotherapy doses and excluded clinical trial participation despite no increased infection risk.

Highlights From This Episode “Unfortunately, because lung cancer is pretty aggressive, we'll see lung cancer mostly in stage IV. So about 50%–55% of all cases are not caught until they are already metastatic, or stage IV. And then about another 25%–30% of cases are caught in stage III, which means they're locally advanced and often not resectable, but we do still treat that with curative intent with concurrent chemoradiation. And then 10%–20% of cases are found in the early stage, and that's stage I and II, where we can do surgical approaches.” TS 2:53 “The majority of radiation that you're going to see is for patients with stage III disease that's inoperable. At my institution, a lot of stage III is inoperable. Now, neoadjuvant immunotherapy has changed that a little bit. But if you have several big, bulky, mediastinal lymph nodes that makes you stage III, surgery is probably not going to be a great option. So we give curative-intent chemoradiation to these patients.” TS 10:51 “Oligoprogression would mean they have metastases but only to one site. And sometimes we will be aggressive with that. Particularly, there's good data, if the only site of progression is in the brain, we can do stereotactic radiation to the brain and then treat the chest with concurrent chemoradiation as a more definitive approach. But outside of that, the majority of stage IV lung cancer is going to be treated with systemic therapy.” TS 15:00 “It's important for nurses to know that there's a lot of different options now for treatment. Probably one of the most important things is making sure patients are aware of what their biomarker status is, what their PD-L1 expression level is, and make sure those tests have been done. … It's good that the patients understand that there's a myriad of options. And a lot of that depends on what we know about their cancer, and then that guides our treatment.” TS 31:05

În perioada sărbătorilor de iarnă, în Regatul Unit, aportul caloric zilnic poate atinge valori de aproximativ 6000 kcal — similare cu cele înregistrate de cicliștii din Turul Franței — în timp ce nivelul de activitate fizică scade semnificativ. Acest exemplu ilustrativ susține un model alternativ propus de cercetători, conform căruia episoade scurte, dar intense, de dezechilibru energetic — determinate de perturbări ale rutinei zilnice — pot conduce la creșteri ale masei adipoase. Aceste perturbări, denumite „instabilitate comportamentală”, sunt frecvent asociate cu tranziții importante din viață, precum începutul studiilor universitare, debutul parentalității sau alte schimbări majore.Date recente contrazic astfel modelul tradițional conform căruia acumularea țesutului adipos are loc prin mici surplusuri calorice susținute în timp. În locul unei acumulări lente și constante, aceste fluctuații bruște pot avea un impact major asupra masei corporale, fără ca ele să fie neapărat evidente în evaluările medicale periodice.Un studiu recent, publicat în International Journal of Obesity, atrage atenția asupra rolului important al perturbărilor stilului de viață în acumularea excesivă de țesut adipos și evidențiază măsurile necesare pentru prevenirea și intervenția eficientă în aceste situații.Obezitatea este asociată cu un risc crescut de boli cardiovasculare, diabet zaharat de tip 2 și anumite forme de cancer.

''Prvič sem jih videl takoj po vojni. Griče, ki so me spominjali na gola trupla, na katerih ni več niti kože.'' Tako je podobnost med telesom in pokrajino opisal svetovno priznani slikar, grafik in risar Zoran Mušič, rojen 12. februarja 1909 v Bukovici, ki si je še posebej mesto v evropskem likovnem prostoru utrdil prav z ekspresivnimi podobami iz koncentracijskega taborišča Dachau. Ob seriji Nismo poslednji njegov izjemno bogat opus obsega še krajinske motive, portrete in zanj zelo značilne konjičke.

Kuratorka dr. Nelida Nemec pa pravi, da je izbrala, kar se ji zdi pri Zoranu Mušiču najbolj bistveno predvsem v luči prepletanja telesa in pokrajine, zlivanja enega v drugo. Na pomen tega nas je umetnik sam opozarjal, doda Nemec, a smo bili v preteklosti premalo pozorni. Kakorkoli, z dvema razstavama v okviru EPK 2025 se Zoran Mušič simbolično vrača v domače kraje, na Kras in v Brda. Ob tem velja poudariti, da se tretja soba na razstavi v Štanjelu ne končna – nadaljuje se na gradu Dobrovo, zato bi bilo dobro, da bi si obiskovalci ogledali obe razstavi.

Piše Kristina Jurkovič, bereta Igor Velše in Sanja Rejc.. Pri knjižnih recenzijah se običajno posvečamo le besedilu, toda če knjigo za odrasle krasijo ilustracije, kar je precej neobičajno, je treba narediti izjemo; še toliko bolj, ko gre za skladen tandem slike in besede, kot je to v avtobiografski pripovedi Moj kraški pristan avtorice Elizabeth Griffin, kjer čarobne črno-bele jedkanice Alfreda Furlanija čudovito prevajajo avtoričina občutja v podobo. To ponazarja že naslovnica, natančno izrisan igličast gozd, skozi katerega se pretika svetloba in v katerega vodi široka pot, ki ni le prispodoba avtoričinih pohajanj po kraški gmajni, marveč tudi raziskovanja svoje življenjske poti. Ta jo je, kot beremo, pred tridesetimi leti prek mnogih stranpoti pripeljala iz Amerike v zgodovinsko in družbeno občutljivo okolje tržaškega zaledja, kjer si je z možem Italijanom ustvarila družino in kjer še danes poučuje angleščino. Kot se za pristno popotnico spodobi, je Griffinova vedoželjno in občutljivo odprta proti drugemu in drugačnosti. V ospredju knjige stoji njeno odkrivanje še vedno krhkega sobivanja Italijanov in zamejskih Slovencev, še vedno razmejene bližine, kar avtorica zelo dobro ponazori na primeru tamkajšnje nižje srednje šole, kamor hodijo tako italijanski kot slovenski dijaki, a je pouk organiziran tako, da se nikoli ne srečajo. Svoja opažanja in občutenja tujosti, tudi izločenosti, vedno skuša razumeti, prav slednje doživi ob spodletelem poskusu, da bi sinova izšolala v slovenskih šolah. Neprijetni izkušnji navkljub ne neha spoštovati in občudovati slovenske skupnosti, njeno močno voljo po samoohranitvi celo povezuje z lastnim bivanjem: ''Kdove,'' si rečem med vožnjo z dela, ''ali moji slušatelji slutijo, da me spominjajo na Kras, ko pa so tako neustrašni, vztrajni in odločni?'' Sama pri sebi se nasmehnem: ''Kjer sem sprva videla zadržanost, zdaj uziram veliko ljubeznivost in lepoto. Nič drugače ni z mojim bivanjem na Krasu.'' Avtorica Elizabeth Griffin se pred nobeno perspektivo ne zapira, nasprotno, odpira ji nove horizonte in zdi se, da jo ravno zavedanje in sprejemanje raznolikosti vedno bolj ukoreninjata v poprej tujem okolju. Njena zgodba pa je tudi lep preplet makro- in mikrosvetov. Prek svojega vrta se poveže s kraško zemljo, na sprehodih s psom Benom odkriva kraški svet in naleti na marsikatero človeško zgodbo, prek ljubečih portretov posameznih prebivalcev prikaže dinamično mikroklimo svojega kraja. Tako v poglavju Trgovec, trgovina, leta eden od temeljev kraja po lastnikovi smrti postane le še ena v vrsti brezdušnih prodajaln, kamor zahaja vedno manj kupcev. Pripoved tkejo zunanje izkušnje in notranji uvidi oziroma refleksije, ki se najtesneje povežejo ob smrti avtoričinega očeta. Na daljših sprehodih intenzivno začuti očetovo prisotnost in tudi sam Kras, ki kot nekakšen čuteč sopotnik vpija njeno razpoloženje. Zave se, da sta oba, vsak na svoj način, njeni zavetni luki pred življenjem in njegovimi pretresi. V jasnosti tega spoznanja zasije tudi kraška pokrajina na zadnji ilustraciji. Moj kraški pristan je lepa, blaga pripoved o sidranju v tuji deželi, ki postane fizični dom, po dušni plati pa umirjeno bivanje v čisti prisotnosti. Doživljanje sveta skozi prizmo Elizabeth Griffin je pravi bralski balzam in želeli bi si, da bi nas v prihodnje popeljala še na kakšno plovbo.

“It's been known for quite a while that [KRAS] is a mutation that leads to cancer development, but for really over four decades, researchers couldn't figure out a way to target it. And so, it was often considered something that was undruggable. But all of this changed recently. So about four years ago, in 2021, we had the approval of the first KRAS inhibitor. So it's specifically a KRAS G12C inhibitor known as sotorasib,” Danielle Roman, PharmD, BCOP, manager of clinical pharmacy services at the Allegheny Health Network Cancer Institute in Pittsburgh, PA, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about the KRAS inhibitor drug class.

Highlights From This Episode “If we look at specifically non-small cell lung cancer, this KRAS mutation is one of the most frequently detected cancer drivers or driver mutations. It's thought that about a quarter of cases of non-small cell lung cancer have this KRAS mutation, and it's usually a specific amino acid substitution that we see in non-small cell lung cancer, so what's known as KRAS G12C mutation.” TS 2:31 “Both of these agents, sotorasib and adagrasib, have the same mechanism of action. They bind to a pocket, very specifically on the KRAS G12C protein, and they lock it in an inactive state so that it can't cause that downstream uncontrolled signaling to happen. So they're kind of shutting down the signaling, and therefore you don't get that uncontrolled cell growth and proliferation.” TS 4:27 “Another big difference to point out, and one that is often used in clinical practice to differentiate when to use these agents, is specifically adagrasib is known to have activity in patients with metastatic non-small cell lung cancer that have active brain metastases. In the clinical trial, they included patients with active brain metastases, and they found that this drug has great [central nervous system] penetration. And so it may be considered the agent of choice in patients with brain metastases.” TS 7:19 “Other considerations—I think one of the big ones—is that there are a lot of drug interactions. Just specifically calling one out that I think is pretty impactful, is sotorasib has an interaction with acid-suppressing medications. So there is the recommendation to avoid [proton pump inhibitors] and H2 antagonists in patients receiving sotorasib. They can take antacids, but you would need to space those out from their dose of sotorasib.” TS 14:14 “This needs to be a collaborative endeavor to make sure these patients are monitored appropriately. We are putting a lot of responsibility on the patients with all of this. So, again, completely administered generally in the home setting, a lot of monitoring, a lot of adverse effects, need for reporting and management—so there's a lot happening here. And it takes a team to accomplish this and to do it right. And I firmly believe that this is often a collaborative effort between our pharmacy and oncology nursing teams to make this happen. Working together to ensure outreach to patients—I think that patients are often more successful with these medications with early identification of toxicities when we're doing scheduled outreach.” TS 19:44

Molecular differences in the profiles of low grade serous ovarian cancer (LGSOC) and high-grade SOC substantiate the need to find unique, differentiated treatment options for each epithelial ovarian cancer subtype, according to Kathleen N. Moore, MD, MS. CancerNetwork® spoke with Moore, Virginia Kerley Cade Endowed Chair of Cancer Development, associate director of Clinical Research at the Stephenson Cancer Center, director of the Oklahoma TSET Phase I Program and professor in the Section of Gynecologic Oncology the University of Oklahoma Health Sciences Center, about distinguishing low grade serous ovarian cancer from other types of ovarian cancer, current treatment options and clinical trials evaluating new regimens, as well as managing treatment in younger patients with or those seeking to preserve fertility. Moore began by differentiating LGSOC from high grade SOC, stating that this disease typically occurred in younger patients and was primarily characterized by MAP kinase alterations, specifically KRAS and BRAF mutations. She then discussed the emergence of endocrine therapies in this indication owing to the presence of estrogen receptors. Additionally, first line treatment was discussed, with the standard of care defined by primary cytoreduction followed by paclitaxel and carboplatin. She then highlighted multiple clinical trials assessing alternative treatment in this indication, particularly involving the use of letrozole (Femara). Other clinical trials evaluated the use of CDK4/6 inhibition plus fulvestrant or BRAF and MEK inhibition with letrozole, with Moore emphasizing the potential for these studies to shift the treatment paradigm in the frontline setting. Furthermore, she suggested that CDK4/6 inhibition may help enhance responses in patients with recurrent LGSOC. Moore then highlighted treatment concerns for younger patients and those seeking to preserve fertility, while expressing the importance of understanding a patient's goals, which may help optimize outcomes. She concluded by reiterating the importance of designing trials and tailoring treatment considering the molecular profile of LGSOC.

In a conversation with CancerNetwork®, Marwan G. Fakih, MD, spoke about the FDA approval of sotorasib (Lumakras) plus panitumumab (Vectibix), and how it may affect the treatment paradigm for patients with KRAS G12C-mutant metastatic colorectal cancer (CRC). Fakih is a professor in the Department of Medical Oncology & Therapeutics Research, associate director for Clinical Sciences, medical director of the Briskin Center for Clinical Research, division chief of GI Medical Oncology, and co-director of the Gastrointestinal Cancer Program at City of Hope Comprehensive Cancer Center in Duarte, California. According to Fakih, the approval of this combination regimen is a “welcome step” for those with metastatic CRC harboring KRAS G12C mutations. Based on supporting data from the phase 3 CodeBreaK 300 trial (NCT05198934), sotorasib/panitumumab may prolong progression-free survival (PFS) and reduce disease burden in patients while offering improvements in other outcomes vs prior standards of care (SOC) like trifluridine/tipiracil (Lonsurf) and regorafenib (Stivarga). Topline data at the time of the approval showed a median PFS of 5.6 months (95% CI, 4.2-6.3) with sotorasib at 960 mg plus panitumumab vs 2.0 months (95% CI, 1.9-3.9) in the SOC arm, in which patients were assigned to receive trifluridine/tipiracil or regorafenib (HR, 0.48; 95% CI, 0.30-0.78; P = .005). Additionally, the overall response rate was 26% (95% CI, 15%-40%) vs 0% (95% CI, 0%-7%) in each respective arm. Looking ahead, Fakih highlighted the potential next steps for research associated with the sotorasib combination as well as other novel therapeutic strategies in the gastrointestinal cancer space. For example, he described the phase 3 CodeBreaK 301 study (NCT06252649), which will evaluate sotorasib/panitumumab as frontline therapy when administered in combination with folinic acid, fluorouracil, and irinotecan (FOLFIRI) vs FOLFIRI plus bevacizumab (Avastin) in metastatic KRAS G12C-mutant CRC. Other novel agents under development in the space include RAS inhibitors and immunotherapy regimens combining CTLA-4 inhibitors with anti–PD-L1 agents. References 1.

Host Dr. Rafeh Naqash and Dr. Husain discuss how to utilize real-world and clinical trial data to discern the safety of adagrasib (another KRASG12C inhibitor), following sotorasib discontinuation due to hepatotoxicity. TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations where we bring you engaging conversations with authors of clinically relevant and highly significant JCOPO articles. I'm your host, Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Assistant Professor at the OU Stephenson Cancer Center. Today, I'm very excited to be joined by Dr. Hatim Hussain, Professor of Medicine at the University of California, San Diego, and author of the JCO Precision Oncology article, “Adagrasib Treatment After Sotorasib-Related Hepatotoxicity in Patients With KRAS-G12C-Mutated Non-Small Cell Lung Cancer: A Case Series and Literature Review.” This was one of the top downloaded articles of 2024. And the other interesting thing is we generally don't do podcasts for case reports or case series, so this is one of the very few that we have selected for the podcast. And at the time of the recording, our guest disclosures will be linked in the transcript. Dr. Hussain, welcome to our podcast and thank you for joining us today. Dr. Hatim Husain: Thank you Dr. Naqash. Such a pleasure to be here and to speak with you all. Dr. Rafeh Naqash: And for the sake of this podcast, we'll refer to each other using our first names. So again, as I mentioned earlier that this is one of the very few case reports that we have selected for podcasts in JCOPO and the intention was very deliberate because it caters to something that is emerging where we are trying to treat more KRAS mutant patients with different KRAS inhibitors. And you tried to address one very unique aspect of it in this article which pertains to toxicity, especially hepatotoxicity. So for the sake of our listeners who tend to be community oncologists, trainees, academic faculty, can you tell us what are KRAS inhibitors? What is KRAS-G12C? And how do some of these approved KRAS inhibitors try to inhibit KRAS-G12C? Dr. Hatim Husain: Sure. For a long time actually we've not had a selective way to inhibit mutant KRAS. And over the last several years actually now, we've seen some dramatic advances here, particularly with the FDA approval of some of the selective inhibitors against the G12C variant. So KRAS-G12C is an isoform of KRAS that is most common in lung cancer and in fact actually is a transversion mutation in the KRAS gene that is a product of the carcinogen of tobacco. And in fact, the incidence of KRAS-G12C in lung cancer, it's quite astounding where as many KRAS-G12C patients there are, there can be, as you know, more than EGFR patients in certain populations and cohorts. The medicines sotorasib and adagrasib were rationally designed to be selective KRAS-G12C inhibitors. And the way that they do this is that they lock the KRAS protein in the OFF state. KRAS is a protein that oscillates between an ON and an OFF state and by virtue of locking the protein in an OFF state, it has shown inhibition of downstream signaling and mitigation of tumor growth and, in fact, tumor cell death. Dr. Rafeh Naqash: I absolutely love the way you describe the ON and OFF state, the oscillation where the ON is bound to the GTP and the OFF is bound to the GDP. The two KRAS inhibitors as currently FDA approved, as you mentioned, are RAS OFF inhibitors and they're emerging KRAS inhibitors that are RAS ON. So now, as we have known from previous data related to immunotherapy and EGFR TKIs such as osimirtinib where toxicity tends to be a compounded effect when you have osimertinib given within a certain timeline of previous checkpoint therapy, we've seen that in the clinic as the data for these KRAS inhibitors is emerging, you talk about some very interesting aspects and data about what has been published so far with regards to prior use of immunotherapy or chemo immunotherapy and the subsequent use of KRAS inhibitors. Could you elaborate upon that? Dr. Hatim Husain: Sure. So for this population of patients, the first line approved strategy is a strategy that most cases will incorporate immune therapy and chemotherapy. Immune therapy can have some important responses for patients with KRAS-G12C. This may be due to the fact that KRAS-G12C patients may have a higher incidence of prior smoking, perhaps higher mutation burdens in some patients, and perhaps immunogenicity is defined in that context. So the standard of care in the first line currently includes immune therapy or immune therapy and chemotherapy. Where the current FDA approvals for selective G12C inhibitors are are after the first line of therapy. There are a number of trials exploring these medicines in the first line to see if they may be incorporated into a future treatment paradigm. Dr. Rafeh Naqash: Thank you for that explanation. Now, going to what you published in this manuscript, can you help us understand the context of why you looked at this? Even though the data just comprises a case series of a handful of patients, but the observations are very interesting and these are real world scenarios where we often tend to be in situations where an individual has had toxicity on a certain drug and may have some response to that drug, but at the same time, the toxicity is challenging. And then you try to debate whether another drug in the same class might be beneficial without those toxicities. So you've tried to address that to some extent using this data set. So can you elaborate upon the question, the methodology, what you tried to look at, and important observations that you have? Dr. Hatim Husain: Yes, our paper was actually inspired by one of my patients. My patient was a patient who had received chemotherapy and immune therapy and actually in the past, even, you know, additional lines of immune therapies, it was really coming to the edge of where standard treatments would exist. It was right at the same time that these selective inhibitors had been approved and the patient had received sotorasib. And what was remarkable was, when given sotorasib, patient had a very high peak and spike in the transaminases. And we would do different trials of strategies around dose, around interruptions. And it was becoming quite difficult, actually, for the patient to proceed with additional therapy. It was around similar times, actually, and I do want to make a note that the patient was progressing, driven in large fact by the fact that we've had to interrupt the medicine. So we feel and believe that the patient had had inadequate dosing because of the level of toxicity that the patient was having with transaminase increase. So it was around the same time that adagrasib was first commercially available that we were at that point, and we did a trial of adagrasib post-sotorasib, largely driven by necessity, without having additional options to provide this patient in our environment. What was remarkable was when the patient received the adagrasib, there were no spikes in transaminases similar to what we had seen before. And that really led us thinking and to say, “Is this adverse event of transaminase increase or hepatotoxicity, is this a class effect with KRAS-G12C inhibitors, or is it more nuanced than that? Are there different, perhaps, mechanisms by which the medicines may work that may more or less differentially contribute to this adverse event?” And so that inspired us to kind of do a larger analysis, kind of really reach out to a larger network of physicians to gather insights and to gather responses in patients who had had a serial approach of sotorasib and then adagrasib. What we found in this process was, in fact, actually there were many more cases of patients who resembled my patient, where the sequence of sotorasib going to adagrasib may have demonstrated differential contribution of hepatotoxicity in that context. And that really motivated us to put the publication together to due diligence, and in the publication spend a lot of time to kind of outline each patient case in detail around metrics surrounding time from last immune therapy, the number of days on sotorasib, the best response to sotorasib, the interval between sotorasib and adagrasib, the duration of adagrasib and then the grade of hepatotoxicity seen in each of the contexts, and particularly kind of the adagrasib and patient disease status as well. We were quite inspired by the effort to try to, if we do not have randomized data in comparison of one medicine to another, which we do not at this juncture, we do not have a randomized analysis to really diligently and rigorously compare the rates of AEs across each medicine, and even in sequence, we do not have that with immune therapy. But what we felt was trying to get more analysis of this sequential approach of, if patients had received a medicine, had to be taken off because of toxicity and then actually tried on a new medicine, what were those rates? We felt like that was at least some information to try to get at this question. Dr. Rafeh Naqash: And you bring forward a very important point, which is, a lot of times in the real world setting we don't have cross trial comparisons that can be fully applicable, or we don't have trials that compare two drugs of the same class with respect to the AE profile or efficacy. And observations like the one that you described that led to this study are extremely critical in trying to help answer these questions. From a data standpoint, and you allude to it to some extent in your manuscript, the trials that are trying to address combination of KRAS-G12C with immunotherapy, especially sotorasib or adagrasib, can you elaborate on that data, what has been published so far and summarize it for our listeners? Dr. Hatim Husain: So there is data from clinical trials looking at patients actually who have received concomitant immune therapy and sotorasib. What was seen in this, in a real world analysis, was that some patients actually who had received sotorasib within a close proximity of immune therapy, as well as a larger study actually which showed in combination there were higher rates of hepatotoxicity in that context. In fact, there were rates of grade 3 hepatotoxicity. And I think built upon that data there's a recognition in the field that we have to be very diligent in terms of even the clinical trial designs in how to understand the pairing between immune therapy and selective G12C inhibitors. There are many trials that are ongoing, one of the studies that is ongoing is known as the KRYSTAL-7 study, which is evaluating adagrasib in combination with pembrolizumab in the first line. And we await more information on that strategy as well. In the context of sotorasib, because of some of the trials that have shown higher rates of hepatotoxicity, there are some additional trials now looking at sotorasib in combination with chemotherapy, and those also have some information that have been reported as well. Dr. Rafeh Naqash: From a drug development standpoint, as you mentioned, there's always a tendency to combine something with something else. And in my practice, and I'm sure in your practice too, when we do early phase trials, many trials are still focused on choosing the maximum tolerated dose, which may be something that we need to gradually move away from as we try to implement these combinations of multiple antibodies plus some of these target agents from maybe the biological optimal dose rather than the maximal tolerant dose is a better way to look at the drugs, the pharmacokinetic profile, and then see what is likely the safest combination with the most appropriate target engagement. Do you have any thoughts on that or insights on that from a drug development perspective? Dr. Hatim Husain: It's a wonderful question and I think it is a very insightful question and understanding of where we are in space right now. And I agree with you that historically, cancer drug development was really hinged upon medicines that perhaps required higher doses to see a benefit or to inch out kind of marginal increases upon where we were at. Now, in combination with medicines that have non-overlapping mechanisms of action, the concept is: Can there actually be more synergy across an approach using combinatorial strategies rather than just additive effects? And I think that in some cases this is being studied with immune therapy, in some cases actually even in the context of other novel mechanisms for cancer therapy. I think that in my practice, I will really try to see how a patient at an approved dose will respond. But definitely I'm open to the concept that there may be a dose that doesn't have to be the maximally tolerated dose, but rather the dose that responses can be seen and perhaps actually at a lower dose than what drives many toxicities. Dr. Rafeh Naqash: I often describe this to my patients as individual patient dose optimization outside of a clinical trial, where I'm sure you've probably done this, where in older adults maybe a lower dose of osimertinib is tolerated better, or a lower dose of sotorasib or adagrasib for that matter, tolerated better with perhaps a similar level of efficacy, since we don't have comparisons between doses and efficacy so far. So I think in the bigger picture, as we discussed in a nutshell, what I would really like the listeners to understand is as we try to move towards this field of precision medicine targeting more and more of the undruggable genes, there's bound to be a certain level of toxicity patterns that we'll start observing. So I think these real world scenarios which may not be addressed using clinical trials because it is in the real world setting where you cycle one treatment after another after another, which may or may not be allowed in most trials and the real world setting can inform, in certain cases, subsequent trial designs. So I think the most important message, at least that I took from your manuscript, was that these real world observations can make a huge difference and inform practice, even though the data sets may be small. Of course, you want to validate some of these findings in a bigger, broader setting, but proof of concept is there. And I think next time I see an individual in my clinic where I see better toxicity, I'll definitely try to talk to them about subsequent treatment with another KRAS inhibitor, maybe adagrasib or something else, if and when appropriate. Do you have any closing thoughts on some of these things that we discussed? Dr. Hatim Husain: I just want to leave the audience actually with this concept that sometimes we group targeted therapy side effects as being class effects unanimously. And I do think actually that each inhibitor may have different off target effects on where medicine may act. We don't truly understand the mechanism of hepatotoxicity in the context of selective KRAS-G12C inhibitors. One of the hypotheses may be due to off target cysteine reactivity in the numerous off target binding sites that certain medicines may have over others. And just even qualitatively which off target binding sites there may be, and how that may lead to either immunogenic responses and other organs or such. So I do think that we do need more research to understand the mechanism. But I think where we are at right now in this space is not assuming that all medicines are going to have the exact same toxicity. I think especially when patients may not have other options, this is something to consider as well. Dr. Rafeh Naqash: Thank you so much. Now, outside of the scientific insights, Hatim, I know you a little bit from before. And knowing the kind of work that you've done in precision medicine, I'm really interested to know about where you started, how you started, how things have been, and what kind of advice you have for junior faculty fellows who are interested in this field of precision medicine that is becoming more and more exciting as we progress in the oncology space. Dr. Hatim Husain: Thank you, Rafeh. I will say, actually as a medical student, I was actually very interested in oncology, partly because it was then and still remains one disease or a constellation of diseases that just has such a high psychological burden on patients. And through the experiences I've had, I really can understand and relate with that concept. I did my medical school at Northwestern, residency at the University of Southern California, and then my oncology fellowship at Johns Hopkins University. And now I've been on faculty at University of California, San Diego, for about 12 years now. It's been a great experience paralleled with the fact that during these last 12 years, I've really seen how the developments in precision oncology, both targeted therapy as well as immune therapy, have really blossomed and unfolded. A large area of my research in my career has kind of focused on cancer genome and integration of novel technologies to really see how they may have clinical application. When I was in my fellowship and as a young faculty, the liquid biopsy was actually coming into development. And this was hinged upon information that had come forward in the prenatal space where some patients actually who were undergoing prenatal testing during pregnancy were found to have complex karyotypes and genomic alterations and then retrospectively found to have cancer. And doing my fellowship at Johns Hopkins, some of the pioneers in liquid biopsy were my mentors and really kind of instilled in me that passion for really thinking through how cancer genomics can be integrated through time. And some of the research that I have been doing has been looking at clonal evolution of cancer, how cancer is changing over time, and how we can think through the right surveillance strategies to really understand how that change is occurring. The dynamics of ctDNA in retrospective cohorts have been studied and shown that, you know, there can be associations between progression-free survival and other clinical endpoints. The current paper that we are speaking about parallels that in a certain way where, rather than say, looking at clonal evolution and say, the efficacy answer of sotorasib first and then adagrasib and how frequently can adagrasib salvage patients, this looks at it from a different angle around toxicity. And I think that is a key point because, at my core, I really do enjoy the clinical aspect of complex decision making on behalf of patients weighing efficacy and toxicity that they may have as they try to get the best quality of life through this journey.

Panitumumab with Low-Dose Capecitabine as a Maintenance Regimen: A Viable Option?

NEJM This Week — Audio Summaries

BUFFALO, NY - February 18, 2025 – A new #researchpaper was #published in Oncotarget, Volume 16, on February 12, 2025, titled “Could Panitumumab with very low dose Capecitabine be an option as a maintenance regimen." In this study, researchers Doaa A. Gamal, Aiat Morsy, and Mervat Omar from Assiut University Hospital, evaluated a new maintenance treatment for metastatic colorectal cancer (mCRC). Their findings suggest that a combination of two drugs—Panitumumab, a targeted therapy that blocks a protein called epidermal growth factor receptor to slow cancer growth, and low-dose Capecitabine, a chemotherapy drug that converts into 5-fluorouracil (5-FU) inside the body to stop cancer cells from growing and dividing—could help extend survival in patients with mCRC. This regimen appears to be both effective and well-tolerated, especially for patients with wild-type KRAS mCRC who had previously responded to treatment. Colorectal cancer is one of the leading causes of cancer-related deaths worldwide. Standard treatment often involves a combination of chemotherapy and targeted therapies, but many patients face challenges related to treatment toxicity and resistance, which can lead to treatment interruptions. This study tested whether a lower-intensity maintenance treatment could help keep the cancer under control after initial treatment. The study involved 25 mCRC patients with wild-type KRAS and BRAF, who first received six rounds of standard 5-FU-based chemotherapy with Panitumumab. Patients who responded well then switched to a maintenance treatment of Panitumumab every two weeks and a low, continuous dose of Capecitabine. The results showed that patients had a median progression-free survival of 18 months and a median overall survival of 45 months, indicating a strong potential benefit. Patients with metastases detected at the same time as the primary tumor showed a longer progression-free survival than those with metastases appearing later. The treatment was also well tolerated, with only 8% of patients experiencing severe side effects such as skin rash or diarrhea, which were managed with standard treatments. "In our research, the toxicity profile was very acceptable, and no patients needed to stop treatment or had a dose modification due to toxicity." Finding a way to keep cancer under control while reducing side effects is a major goal in cancer treatment. While other maintenance therapies like Bevacizumab and Cetuximab have been studied, this research suggests that Panitumumab with low-dose Capecitabine could be a promising new option. Panitumumab is already an FDA-approved drug, but its role in maintenance therapy had not been extensively explored. The results of this study suggest that this combination may help delay disease progression while keeping side effects manageable, ultimately improving patients' quality of life. Although larger studies are needed, these findings open the door for further clinical trials to confirm the benefits of this regimen. If validated, this approach could change the standard of care for mCRC patients, particularly those who cannot tolerate more intensive chemotherapy.

In a conversation with CancerNetwork® during Pancreatic Cancer Awareness Month, Tanios S. Bekaii-Saab, MD, spoke about various developments in the pancreatic cancer treatment field. Throughout the discussion, Bekaii-Saab weighed the benefits of currently available chemotherapeutic regimens for patients with metastatic disease, discussed research on the potential for precision medicine in those with KRAS wildtype pancreatic ductal adenocarcinoma (PDAC), and detailed ongoing initiatives to improve outcomes among those with RAS mutations and other targetable genomic alterations. Bekaii-Saab is the David F. and Margaret T. Grohne Professor of Novel Therapeutics for Cancer Research, chair and consultant in the Division of Hematology and Medical Oncology at Mayo Clinic in Arizona, and co-leader of Advanced Clinical and Translational Science at Mayo Clinic Cancer Center. Given the prevalence of RAS mutations and other alterations in patients with pancreatic cancer, Bekaii-Saab especially emphasized the use of genomic analysis to inform personalized treatment decision-making in the field. Screening patients to detect aberrations such as microsatellite instability-high tumors, BRAF 600E mutations, KRAS G12C mutations, and NRG1 fusions can open the door for the development and use of targeted agents, which may consequently improve patient outcomes. Looking ahead, Bekaii-Saab noted the need to adapt the therapies that have shown activity in the later stages of the disease to earlier treatment settings. Although “great work” has been achieved with chemotherapy and surgical techniques, he highlighted the importance of bringing targeted agents to earlier lines of therapy to further increase the likelihood of positive outcomes for patients. “I have never been more optimistic. I'm always the eternal optimist, but I'm even more optimistic today that we're going to move the needle for our patients with pancreatic cancer and continue to enhance that likelihood of living longer, having a better quality of life, or even increasing the level of a cure for this cancer,” Bekaii-Sabb stated. “Certainly, the future looks bright. We're chipping away, one drug at a time. We can now remove that whole concept of nihilism in pancreatic cancer and look quite optimistically on the future.”

The OSUCCC -James is a leader in the treatment of pancreatic cancer, with the utilization of robotic Whipple surgery, the use of chemotherapy and radiation before surgery, multiple clinical trials designed to find even better ways to treat patients and a large multidisciplinary pancreatic cancer clinic.“We're always thinking about what's the next step and about the patient of tomorrow, that's a huge driver,” said Susan Tsai, MD, MHS, a surgical oncologist who specializes in pancreatic cancer and is Director of the OSUCCC – James Division of Surgical Oncology. “The pancreas helps regulate blood sugars and also helps you digest food,” Tsai explained, adding that it's hard to diagnose, which means patients often come to her with later-stage cancer. “In 70 to 80 percent of the patients we see, they will have recurrent disease somewhere else in their body,” Tsai said, adding this statistic has led to a new way to treat patients. “In the old days we'd often rush patients to surgery to remove the cancer as quickly as possible, but because the recurrence rates were so high maybe that isn't the best way to treat patients. Now, we utilize systematic therapy [chemotherapy and radiation] upfront, before surgery and we're seeing better results.” The development of robotic Whipple surgery to perform the complex and invasive pancreatic cancer surgery is another innovation. Using previous surgical techniques “there was about a 30 percent mortality rate,” Tsai said, adding the advances of the less-invasive and more precise Whipple surgery “practiced at a high-volume comprehensive cancer center such as the James have reduced that to less than 3 percent.” To date, pancreatic cancer has not been a good target for immunotherapy. “Now, we have been able to target a genetic mutation, called KRAS, a gene that drives many different types of cancer,” Tsai said, adding clinical trial are now testing drugs that appear to be able to target KRAS and enable the immune system to recognize and attack them. In another, soon-to-open clinical trial in which Tsai helps lead, the molecular profile of a biopsy of a patient's pancreatic cancer is analyzed to determine which chemotherapy drug to utilize. “This could be a great resource for patients,” Tsai said.

BUFFALO, NY - November 4, 2024 – A new #casereport was #published in Oncotarget's Volume 15 on October 11, 2024, entitled “A case of adenosquamous pancreatic cancer with a KRAS G12C mutation with an exceptional response to immunotherapy.” This case report highlights a remarkable and unexpected response to immunotherapy in a patient with metastatic adenosquamous pancreatic cancer (ASCP), a rare and aggressive form of pancreatic cancer. The study, led by Murtaza Ahmed, Brent K. Larson, Arsen Osipov, Nilofer Azad, and Andrew Hendifar from Cedars-Sinai Medical Center and Johns Hopkins University, provides new hope for ASCP patients, who are traditionally underserved by current treatment options. The team documented a 68-year-old male with metastatic ASCP carrying a KRAS G12C mutation. Unexpectedly, after limited success with standard therapies, the patient's cancer responded significantly to pembrolizumab, a type of immune checkpoint inhibitor, despite the absence of typical markers indicating suitability for immunotherapy. Pancreatic cancer remains one of the most lethal cancer types, with few advancements in effective treatments for its rarer forms, such as ASCP, which accounts for only 1-10% of all pancreatic cancer cases. Traditionally, ASCP has been treated with chemotherapy based on protocols for the more common pancreatic ductal adenocarcinoma, despite the distinct tumor characteristics. This case suggests that ASCP's unique tumor microenvironment may make it more receptive to immunotherapy. Researchers are hopeful that this new understanding will drive clinical trials focused on immunotherapy specifically for ASCP patients, potentially offering new options for those with limited treatment success. “To that point, there is an active multi-center phase 2 trial investigating outcomes and responses to ICI in patients with metastatic or unresectable ASCP or ampullary cancer.” In conclusion, this report signals a potential shift in the treatment of rare and aggressive pancreatic cancer subtypes like ASCP. As oncology increasingly embraces personalized medicine, cases like this one open new avenues for patients who were not responsive to traditional therapies, potentially transforming the management of previously intractable cancers.

While Circio's legacy is in cancer immunology (it still boasts a cancer vaccine candidate targeting KRAS driver mutations), the company made a bold pivot, of sorts, when it committed headlong to the circular RNA future. Now, it's in the throes of fine-tuning a platform for the development of novel circRNA medicines for rare disease, vaccines, and cancer. On this episode of the Business of Biotech, we go deep inside the story behind the pivot, we explore the RNA therapeutic platform-versus-product appetite among biotech investors, and Dr. Digman Wiklund shares insights into the challenges his company overcame to enable such a dramatic shift in focus.

Dr. Shaalan Beg and Dr. Arturo Loaiza-Bonilla discuss the potential of artificial intelligence to assist with patient recruitment and clinical trial matching using real-world data and next-generation sequencing results. TRANSCRIPT Dr. Shaalan Beg: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Shaalan Beg, your guest host for the podcast today. I'm an adjunct associate professor at UT Southwestern's Simmons Comprehensive Cancer Center in Dallas and senior advisor for clinical research at the National Cancer Institute. On today's episode, we will be discussing the promise of artificial intelligence to improve patient recruitment in clinical trials and advanced clinical research. Joining me for this discussion is Dr. Arturo Loaiza-Bonilla, the medical director of oncology research at Capital Health in Philadelphia. He's also the co-founder and chief medical officer at Massive Bio, an AI-driven platform that matches patients with clinical trials and novel therapies. Our full disclosures are available in the transcript of this episode. Arturo, it's great to have you on the podcast today. Dr. Arturo Loaiza-Bonilla: Thanks so much, Shaalan. It's great to be here and talking to you today. Dr. Shaalan Beg: So we're all familiar with the limitations and inefficiencies in patient recruitment for clinical trials, but there are exciting new technologies that are addressing these challenges. Your group developed a first-in-class, AI-enabled matching system that's designed to automate and expedite processes using real-world data and integrating next-generation sequencing results into the algorithm. You presented work at the ASCO Annual Meeting this year where you showed the benefits of AI and NGS in clinical trial matching and you reported about a twofold increase in potential patient eligibility for trials. Can you tell us more about this study? Dr. Arturo Loaiza-Bonilla: Absolutely. And this is just part of the work that we have seen over the last several years, trying to overcome challenges that are coming because of all these, as you mentioned, inefficiencies and limitations, particularly in the manual patient trial matching. This is very time consuming, as all of us know; many of those in the audience as well experience it on a daily basis, and it's resource intensive. It takes specialized folks who are able to understand the nuances in oncology, and it takes, on average, even for the most experienced research coordinator or principal investigator oncologist, 25 minutes per trial. Not only on top of that, but in compound there's a lack of comprehensive genomic testing, NGS, and that complicates the process in terms of inability to know what patients are eligible for, and it can delay also the process even further. So, to address those issues, we at Massive Bio are working with other institutions, and we're part of this … called the Precision Cancer Consortium, which is a combination of 7 of the top 20 top pharma companies in oncology, and we got them together. And let's say, okay, the only way to show something that is going to work at scale is people have to remove their silos and barriers and work as a collaborative approach. If we're going to be able to get folks tested more often and in more patients, assess for clinical trials, at least as an option, we need to understand further the data. And after a bunch of efforts that happened, and you're also seeing those efforts in CancerX and other things that we're working on together, but what we realize here is using an AI-enabled matching system to basically automate and expedite the process using what we call real-world data, which is basically data from patients that are actually currently being treated, and integrating any NGS results and comparing that to what we can potentially do manually. The idea was to do multi-trial matching, because if we do it for one study, yeah, it will be interesting, but it will not show the potential applicability in the real world. So with all that background, the tool itself, just to give you the punchline of it, was proven highly effective in terms of efficiency. We were able to increase the number of potential matches, and not only that, but reducing the time to the matching. So basically, instead of spending 25 minutes, it could be done in a matter of seconds. And when you compound all that across multiple clinical trials, in this case, it was several sponsors coming together, we were able to reduce the manual effort of seeing patients and testing for clinical trials to basically 1 hour when it would have otherwise taken a ridiculous amount of time. And it was quantified as 19,500 hours of manual work, compared to 1 hour done by the system to uniquely match a cohort of about 5,600 patients that came into the platform. And this was across 23 trials. Now imagine if we can do it for the 14,000 clinical trials currently in clinicaltrials.gov. So for us, this kind of was an eye-opening situation that if we can increase not only the efficiency but find even more trials by integrating comprehensive genomic testing, which in this case was a twofold increase in eligibility for clinical trials, that gives us not only the opportunity for optimized processes using AI but also a call to action that there is still a lot of under-genotyping. And I know American Cancer Society and ASCO and many others are working hard on getting that into fruition, but we need to have systems that remind us that certain patients are not tested yet and that can improve not only real patients, but the R&D and the process of innovation in the future. Dr. Shaalan Beg: Yeah, it's always an important reminder that even some of the highest impact IT solutions or AI solutions are most effective if they can be integrated into our normal clinical processes and into the normal workflow that we have in our clinics to help clinicians do their work quickly and more efficiently. Can you talk about how, over the last few years, the availability of NGS data in our electronic medical record (EMR) has evolved and whether that's evolving for the better? And what are some next steps in terms of making that data available at EMR so that such solutions can then pull that data out and do clinical trial matching? Dr. Arturo Loaiza-Bonilla: Yes. So one of the things that we have seen over the last couple of years is because of the applicability of the 21st Century Cures Act, there is less “information blocking,” which is patients not being able to access their information in real time. Now, with the appearance of health exchanges, with patient-centric approaches, which is something that many innovators, including ours, are trying to apply, it's really becoming more relevant. So it's not only helping us to find the patients when they really need to get tested, but also is giving us the opportunity to put those patients into the right treatment pathway when found. Something that's still a challenge and I think we can work by being more collaborative once again – is my dream – is having these pre-screening hubs where no matter where you are in your cancer journey, you just go into that funnel and then are able to see, “Okay, you are in the second-line setting for non-small cell lung cancer, EGFR-mutated. Now, do you have a meta amplification, then you go for this study or this trial. Oh, you haven't been tested yet. You should get tested. You're a pancreas cancer patient who is KRAS wild type; well, there is a significant chance that you may have a biomarker because that's where most patients are enriched for.” So having that opportunity to at scale, just for the whole country, to get those patients access to that information, I think is crucial for the future of oncology. And I think you working at the NCI, more than most, know how the impact of that can help for those underrepresented patients to get more access to better treatment options and whatnot. And we can activate clinical trials as well in new models, decentralized models, adjusting time models, all those things can be leveraged by using biomarker testing in real time. Identification when the patient really needs a trial option or a medication option, because the data is telling us when to activate that in real time. Dr. Shaalan Beg: And identifying the patient for a potential clinical trial is one challenge. In oncology, given a lot of our trials, we are looking to enroll people at a specific time in their disease journey. So we call it first-line or second-line or third-line, becomes the next challenge. So just knowing someone has mutation number 1, 2, or 3 isn't enough to say they would be eligible for a second-line BRAF X, Y and Z mutation at a given trial. I've heard you talk a lot about this last-mile navigation for people once you've identified that they may be a soft match for a clinical trial. Can you talk about what you've seen in the ecosystem being developed on how AI is helping both clinics and patients navigate this last mile from the time they're identified for a clinical trial to the time they actually receive cycle 1, day 1? Dr. Arturo Loaiza-Bonilla: Yeah, absolutely. And that is such a critical point because, as you know, we have helped tons of patients getting trial options in thousands of cases. But even my own patients, I give them a report for trial options and they're like, “Okay, I still need help.” And we have been talking with ASCO, with the American Cancer Society, and many other very good teams, and what we see as an opportunity in technology here is leveraging those cancer journeys to know when the patient really has the opportunity to enroll in a trial, because this is a very dynamic environment. Not only the patient's condition changes because their cancer progresses, the hemoglobin changes, the cancer moves from one place to the other, and there's nuances in between, but also new medications are coming up, studies open and close, sites open and close. So having this information as a hub, as what we call a command center, is the key to make this happen. And we can use the same tools that we use for Uber or for Instacart or whichever thing you want to do; it's already the same concept. When you need groceries, you don't need groceries every day. But Amazon gives you a ding that's like, “Well, I think you may be running out of milk,” because they already know how often you buy it, or just having the data behind the scenes of how typically these, in this case, patient journeys, may manifest based on the biomarker. So let's say a smoldering multiple myeloma is not the same across. One patient with biomarkers that make them very high risk, the risk of progressing to a multiple myeloma, first-line treatment-eligible patient is going to be much different than someone who has better risk cytogenetics. So using that tool to optimize the cancer journeys of those patients and being able to notify them in real time of new trial options, and also knowing when the patient really has that disease progression so there's a time of activation for trial matching again, the same way you get a credit score for buying a house, then you know exactly what options are in front of you at that very moment. And that is the last-mile component, which is going to be key. What we have seen that we feel is important to invest on, and we have invested heavily on it, is that until the patient doesn't sign the consent form for the clinical trial, that patient is completely unknown to most people. The site doesn't know them because they haven't been there, and they may be there, but they don't know about the options sometimes. But no one's going to invest in getting that patient to the finish line. There's a lot of support for patients on trials, but not before they enroll on trials. And we feel that this is a big opportunity to really exponentially grow the chances of patients enrolling in trials if we support them all the way from the very time they get diagnosed with cancer in any setting. And we can help that patient on a very unique journey to find the trial options using technology. So it's very feasible. We see it once again in many other equally complex tasks, so why not do it in oncology when we have all the bonafides across wanting to do this. Dr. Shaalan Beg: Can you give examples of where you are seeing it done outside of oncology that's a model that one can replicate? Dr. Arturo Loaiza-Bonilla: I mean, oncology is the toughest use case to crack. You have experiences with DCTs in the past and all that. So the big opportunities are for patients, for example, in psychiatry, when they need certain counseling and help. We see that also in medical devices, when people have diabetes and they really need a device specifically for that unique situation, or also for patients with cardiovascular risk that they can in real time get access to novel therapeutics. And that's how they have been able to enroll so quickly. And all these GLP-1 inhibitors, all those models are really almost completely decentralized nowadays in something that we can extrapolate for oncology once we have aligned the ecosystem to make it see them. This is something that we can really revolutionize care while we manage all the complex variables that typically come with oncology uses. Dr. Shaalan Beg: I would imagine while you translate those learnings from outside of oncology into oncology, a lot of those processes will be human and AI combination activities. And as you learn more and more, the human component becomes a smaller fraction, and the technology and the AI becomes more of a component. Are you seeing a similar transition in the clinical trial matching space as well? Dr. Arturo Loaiza-Bonilla: Yes. So that's why people say humans are going to be replaced. They're not. Patients still want to see a human face that they recognize, they trust. Even family members of mine want to hear from me, even if they are in the top place in the world. What we can change with technology are those things that are typically just friction points. In this case, information gathering, collecting records, getting the data structured in a way that we can use it for matching effectively, knowing in real time when the patient progresses, so we can really give them the chances of knowing what's available in real time. And collecting the information from all these other stakeholders. Like, is the site open? Is the budget approved for that place? Is the insurance allowing the specific … do they have e-consent? Those things can be fully automated because they're just burdensome. They're not helping anyone. And we can really make it decentralized for e-consent, for just getting a screening. They don't need to be screened at the site for something that they're going to receive standard of care. We can really change that, and that's something that we're seeing in the space that is changing, and hopefully we can translate it fully in oncology once we are getting the word out. And I think this is a good opportunity to do so. Dr. Shaalan Beg: You talked about your dream scenario for clinical trial matching. When you think about your dream scenario as a practicing oncologist, what are the AI tools that you are most excited about making their way into the clinic, either wishful thinking or practically? Dr. Arturo Loaiza-Bonilla: I typically get feedback from all over the place on doing this, and I also have my own thoughts. But I always come to this for a reason. We all became physicians and oncologists because we like being physicians. We like to talk to patients. We want to spend the time. I tell folks in my clinic, I will see a thousand patients all the time as long as I don't have to do notes, as long as I don't have to place orders. But of course, they will have to hire 1,000 people ancillary to do all the stuff that we do. If we can go back and spend all that time that we use on alert fatigue, on clicking, on gathering things, fighting insurance, and really helping align those incentives with clinical trials and biomarker testing and really making it a mankind or a humankind situation where we're all in this really together to solve the problem, which is cancer, that will be my dream come true. So I don't have to do anything that is clerical, that is not really helping me, but I want to use that AI to liberate me from that and also use the data that is generated for better insights. I think that I know my subject of expertise, but there's so many things happening all the time that it is hard to keep up, no matter how smart you are. If the tool can give me insights that I didn't even know, then leverage that as a CME or a board certification, that would be a dream come true. Of course, I'm just dreaming here, but it's feasible. Many of these ideas, as I mentioned, they're not new. The key thing is getting them done. The innovative part is getting stuff done, because I'm sure there's a gazillion people who have the same ideas as I did, but they just don't know whom to talk to or who is going to make it happen in reality. And that's my call to action to people: Let's work together and make this happen. Dr. Shaalan Beg: Well, Arturo, thanks a lot for sharing your insights with us today on the ASCO Daily News Podcast.

In this research paper, researchers demonstrate a promising new treatment option for refractory metastatic gastrointestinal cancers using a combination of two FDA-approved drugs. Researchers Jun Zhang, Lanlan Zhou, Shuai Zhao, and Wafik S. El-Deiry from Fox Chase Cancer Center and Brown University explore the potential of combining TAS102 (trifluridine/tipiracil) and regorafenib as a treatment option for gastrointestinal (GI) cancers. Their research paper, published in Oncotarget's Volume 15 on July 2, 2024, is entitled, “Regorafenib synergizes with TAS102 against multiple gastrointestinal cancers and overcomes cancer stemness, trifluridine-induced angiogenesis, ERK1/2 and STAT3 signaling regardless of KRAS or BRAF mutational status.” The Study The combination of two FDA-approved drugs, TAS102 and regorafenib, has shown promising results in preclinical studies. TAS102 is an oral formulation consisting of trifluridine (FTD) and tipiracil hydrochloride (TPI). It has been approved by the US FDA for the treatment of refractory metastatic colorectal cancer and metastatic gastric cancer. Regorafenib is a multi-target tyrosine kinase inhibitor that inhibits tumor angiogenesis and cell proliferation and is approved for the treatment of gastrointestinal cancers. Recent studies have shown that TAS102, in combination with regorafenib, can lead to improved survival and restrict tumor progression. The combination therapy has been found effective in multiple gastrointestinal cancer cell lines, including colorectal, gastric, and pancreatic cancers.
