Podcast appearances and mentions of angela demichele

Drs. John Sweetenham and Angela DeMichele discuss potentially ground-breaking abstracts in breast and lung cancer as well as notable research on artificial intelligence and its impact on cancer care, all of which were featured at the 2024 ASCO Annual Meeting.  TRANSCRIPT Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham from UT Southwestern's Harold C. Simmons Comprehensive Cancer Center and host of the ASCO Daily News Podcast. My guest today is Dr. Angela DeMichele, the Marianne and Robert McDonald Professor in Breast Cancer Research and co-leader of the Breast Cancer Program at the University of Pennsylvania's Abramson Cancer Center. Dr. DeMichele also served as the chair of the 2024 ASCO Annual Meeting Scientific Program. Today, she'll be sharing her reflections on the Annual Meeting and we'll be highlighting some advances and innovations that are addressing unmet needs and accelerating progress in oncology.  Our full disclosures are available in the transcript of this episode.  Dr. DeMichele, congratulations on a very robust and highly successful program at ASCO24, and thanks for joining us on the podcast today. Dr. Angela DeMichele: Well, thanks so much for having me, Dr. Sweetenham. It's a pleasure to be here.  Dr. John Sweetenham: The presidential theme of the Annual Meeting this year was the "The Art and Science of Cancer Care: From Comfort to Cure." And this was certainly reflected throughout the meeting in Chicago that welcomed more than 40,000 attendees from across the globe. I know our listeners will be interested to hear some of your own reflections from the meeting now that we're on the other side of it, so to spea  Dr. Angela DeMichele: Yes. Well, I will say that playing this role in the annual meeting really was a highlight of my career, and I feel so fortunate to have had the opportunity to do it. We had over 200 sessions, and in many, if not all of these sessions, we really tried to make sure that there was a case that really sort of grounded the session to really help people understand: you're going to hear about science, but how are you going to apply that? Who is the patient for whom this science really is important?  We had over 7,000 abstracts submitted, and our 25 tracks and their chairs really pulled through to find really the best science that we could present this year. I think what you saw really was a representation of that across the board: incredible advances in lung cancer, breast cancer, melanoma, GI cancers; also really cutting-edge technologies: AI, as we'll talk about in a little while circulating markers like ctDNA, new drug development, new classes of drugs. So it was really an exciting meeting. I mean, some highlights for me, I would say, were certainly the Plenary, and we can talk a little bit about that. Also, we had a fantastic ASCO/AACR Joint Session on “Drugging the “Undruggable Target: Successes, Challenges, and the Road Ahead.” And, if any of the listeners have not had a chance to hear this, it's really worth going in and watching this because it really brought together three amazing speakers who talked about the successes in KRAS, and then really, how are we using that success in learning how to target KRAS to now targeting a variety of other previously thought to be undruggable targets. I learned so much. And there's really both the academic and the pharma perspective there. So I'd really encourage watching this session. The other session that I really thought was terrific was one that I was honored to chair, which was a fireside chat (“How and Where Will Public Investment Accelerate Progress in Oncology? A Discussion with the NIH and NCI Directors”) with both Dr. Monica Bertagnolli, who is the director of the NIH, and Dr. Kim Rathmell, who's now the director of the NCI. And boy, I'll tell you, these two incredibly smart, thoughtful, insightful women; it was a great conversation. They were really understanding of the challenges we face conducting research, practicing medicine. And maybe different from leadership at the NIH in the past, they've really taken the approach to say that everything they do is focused on the patient, and they don't limit themselves to just research or just science, that everything that the NIH does, and particularly the NCI does, really has to be focused on making sure we can give patients the best possible care. And I think they're being very thoughtful about building important infrastructure that's going to take us into the future, incorporating AI, incorporating new clinical trial approaches that are going to make it faster and easier to conduct clinical trials and to get the results that we need sooner. So just a few of the highlights, I think, from some really interesting sessions. Dr. John Sweetenham: It certainly was an extremely enriching and impactful ASCO24. And I think that the overall theme of the meeting was extremely well reflected in the content with this amazing mix of really, truly impactful science, along with a great deal of patient-centered healthcare delivery science to accompany it. So, I completely agree with you about that. There was a lot, of course, to take in over the five days of the meeting, but I'm sure that our listeners would be very interested to hear about one or two abstracts that really stood out for you this year.  Dr. Angela DeMichele: Sure. I'm a breast cancer specialist, so I can't help but feel that the late breaking abstract, the DESTINY-Breast06 trial, was really important for the field of breast cancer. So just briefly, this is a study of the antibody drug conjugate T-DxD, trastuzumab deruxtecan. This is a drug that is actually now approved in metastatic breast cancer, really effective in HER2-positive disease. But the question that this trial was trying to answer is, can this drug, which is built with the herceptin antibody against HER2, then linked to a chemotherapeutic molecule, can this work even in the setting of very, very low HER2 expression on a tumor? I think this is an incredibly important question in the field of antibody drug conjugates, of which there are now many across diseases, is how much of the target do you really need to have on the surface of the tumor?  We had seen previously HER2 overexpressing tumors respond really well to this drug. HER2 tumors that have an intermediate level of expression were tested in the DP04 trial, and we saw that even those 2+ intermediate tumors responded well to this drug. The DP06 trial that was presented at ASCO was looking at this group of patients that have even less HER2 on the surface. So we typically measure HER2 by immunohistochemistry as 0, 1+, 2+, or 3+. And this was looking at patients whose tumors were over 0, but were at 1+ or below, so low and ultra-low. And it turned out that compared to treatment of physician's choice, the drug really had quite a lot of activity, even in these patients who have very little HER2 on their tumors, really showing progression-free survival benefits in the HER2-low and HER2-ultra-low groups that were appreciable on the order of about 5 months, additional progression free survival hazard ratios around 0.6, so really demonstrating that utilizing an antibody drug conjugate, where you've got very little target, can still be a way to get that drug to a tumor.   And I think it'll remain to be seen whether other ADCs can have activity at very low levels of IHC expression of whatever target they're designed against. I think one of the tricky things here for implementing this in breast cancer will be how do pathologists actually identify the tumors that are ultra-low because it's not something that we typically do. And so we'll go through a period, I think, of adjustment here of really trying to understand how to measure this. And there are a bunch of new technologies that I think will do a better job of detecting low levels of the protein on the surface of the tumor because the current IHC test really isn't designed to do that. It was only designed to be focused on finding the tumors that had high levels. So we have some newer technologies with immunofluorescence, for example, that can really get down to very low levels. And I think this is going to be a whole new area of ADCs, target detection – how low can you go to still see activity? So I thought that this was an important abstract for many reasons.  I will just say the second area that I was really particularly impressed with and had a big impact on me were the two lung cancer abstracts that were presented in the Plenary, the LAURA trial (LBA4) and the ADRIATIC trial (LBA5). And I think, I've been in the field of oncology for 30 years now, and when I started in the late ‘90s, lung cancer was a disease for which we had very few treatments. If we didn't catch it early and surgery wasn't possible for non-small cell lung cancer, really, it was a horrible prognosis. So we knew this year was the 20th anniversary of the discovery of EGFR as a subtype of lung cancer. That was really, I think, a turning point in the field of non-small cell lung cancer – finding a target. And now seeing the LAURA trial show that osimertinib really had such an enormous impact on progression-free survival amongst these patients who had EGFR-positive non-small cell lung cancer, progression-free survival hazard ratio of 0.16; there was a standing ovation.  And one of the really big privileges of being the Scientific Program Chair is getting to moderate the Plenary Session, and it's a really amazing experience to be standing up there or sitting there while the presenter is getting a standing ovation. But this was well deserved because of the impact this is having on patients with EGFR positive lung cancer. And it was similar with the ADRIATIC trial, which looked at the benefits of adding immunotherapy in limited-stage small-cell lung cancer. Again, a disease that treatment has not changed in 30 years, and so the addition of durvalumab to the standard backbone of chemotherapy for small cell lung cancer had its survival advantage. These patients are living longer and it was really an impressive improvement. And I think it really underscores just the revolution that has happened in lung cancer between targeted therapy and immunotherapy has completely changed the prognosis for patients with this disease. So to me, these were really landmark reports that came out at ASCO that really showed us how far we've come in oncology. Dr. John Sweetenham: Yeah, absolutely. I think that, as you mentioned, those results are truly remarkable, and they reflect extraordinary advances in science. I think we see that both in terms of the therapeutic arena, but also, I think we've started to see it in other areas as well, like symptom control, remote patient monitoring, and so on and so forth, where some of the newer virtual technologies are really having major impacts as well. Dr. Angela DeMichele: Yes, we really wanted to have a focus on artificial intelligence in this meeting, because it's having such an enormous impact on our field in everything from care delivery to diagnostics. I'd love to hear what you thought was the most interesting, because there really was just new data across the board presented. Dr. John Sweetenham: I've actually chosen 3 abstracts which I thought were particularly interesting for a couple of reasons, really. They're all based on virtual health interventions, and I think they're interesting in really reflecting the theme of the meeting, in that they are extremely advanced technology involved in the virtual platforms, a couple of which are artificial intelligence, but very impactful to patients at the same time in terms of remote symptom control, in terms of addressing disparities, and in one case, even influencing survival. So I thought these were three really interesting abstracts that I'll walk the listeners through very quickly.  The first of these was a study, Abstract 1500 (“National implementation of an AI-based virtual dietician for patients with cancer”) which looked at an artificial intelligence-based virtual dietitian for patients with cancer. This is based on the fact that we know nutritional status to be a key driver of patient experience and of cancer outcomes. And as the authors of the presentation noted, 80% of patients look for nutritional support, but many of them don't get it. And that's primarily a workforce issue. And I think that's an important thematic point as well, that these new technologies can help us to address some of the workforce issues we have in oncology. So this was an AI-based platform developed by experts in nutrition and cancer patients, based on peer reviewed literature, and a major effort in terms of getting all of these data up together. And they developed an artificial intelligence platform, which was predominantly text message based. And this platform was called INA. And as this is developing as a platform, there's a machine learning component to it as well. So in theory, it's going to get better and better and better over time.  And what they did in their study was they looked at little over 3,000 patients across the entire country who were suffering from various types of cancer, GU, breast, gynecological malignancy, GI and lung. And most of them had advanced-stage disease, and many of them had nutritional challenges. For example, almost 60% of them were either overweight or obese by BMI. And the patients were entered into a text exchange with the AI platform, which would give them advice on what they should eat, what they shouldn't eat. It would push various guidance and tips to them, it would develop personalized recipes for them, and it would even develop menu plans for the patients. And what's really interesting about this is that the level of engagement from the patients was very high, with almost 70% of patients actually texting questions to this platform. About 80% of the patients completed all of the surveys, and the average time that patients interacted with the platform was almost nine months, so this was remarkable levels of engagement, high levels of patient satisfaction. And although at this point, I think it's very early and somewhat subjective, there was certainly a very positive kind of vibe from patients. Nearly 50% have used the recommended recipes. More than 80% of them thought that their symptoms improved while they were using this platform. So I think as a kind of an assistant for remote management of patients, it's really remarkable. And the fact that the level of engagement was so high also means that for those patients, it's been very impactful.   The second one, this was Abstract 100 (“AI virtual patient navigation to promote re-engagement of U.S. inner city patients nonadherent with colonoscopy appointments: A quality improvement initiative”) looked again at an AI-based platform, which in this case was used in an underserved population to address healthcare disparities. This is a study from New York which was looking at colorectal cancer screening disparities amongst an underserved population, where historically they've used skilled patient navigators to address compliance with screening programs, in this case specifically for colorectal cancer. And they noticed in the background to this study that in their previous experience in 2022, almost 60% of patients either canceled or no-showed for colonoscopy appointments. And because of this and because of the high burden of patients that this group has, they decided to take an AI-based virtual patient navigator called MyEleanor and introduce this into their colorectal cancer screening quality improvement.  And so they introduced this platform in April of 2023 through to the end of the year, and their plan was to target reengagements of around 2,500 patients who had been non adherent with colonoscopy appointments in a previous year. And so the platform MyEleanor would call the patients to discuss rescheduling, it would assess their barriers to uptake, it would offer live transfer to somebody to schedule for them, and then it would go on closer to the point of the colonoscopy to call the patients and give them advice about their prep. And it was very nuanced. The platform would speak in both English and Spanish versions. It could detect nuances in the patient's voice, which might then trigger it to refer the patient to a live agent rather than the AI platform. So, very sophisticated technology. And what was most interesting about this, I think, was that over the eight months of the study, around 60% of patients actually engaged with this platform, with almost 60% of that group, or 33% overall, accepting a live transfer and then going on to scheduling, so that the completion rate for the no show patients went from 10% prior to the introduction of this platform to 19% after it was introduced. So [this is] another example, I think, of something which addresses a workforce problem and also addresses a major disparity within cancer care at the moment by harnessing these new technologies. And I think, again, a great interaction of very, very high-level science with things that make a real difference to our patients.  So, Dr. DeMichele, those are a couple of examples, I think, of early data which really are beginning to show us the potential and signal the impact that artificial intelligence is going to have for our patients in oncology. I wonder, do you have any thoughts right now of where you see the biggest impact of artificial intelligence; let's say not in 20 years from now, but maybe in the next year or two?  Dr. Angela DeMichele: Well, I think that those were two excellent examples. A really important feature of AI is really easing the workload on physicians. And what I hope will happen is that we'll be able to use AI in the very near future as a partner to really offload some of the quite time-consuming tasks, like charting, documentation, that really take us away from face-to-face interaction with patients. I think this has been a very difficult period where we move to electronic medical records, which are great for many reasons, but have really added to the burden to physicians in all of the extra documentation. So that's one way, I think, that we will hope to really be able to harness this. I think the other thing these abstracts indicate is that patients are very willing to interact with these AI chatbots in a way that I think, as you pointed out, the engagement was so high. I think that's because they trust us to make sure that what we're doing is still going to be overseen by physicians, that the information is going to get to us, and that they're going to be guided. And so I think that in areas where we can do outreach to patients, reminders, this is already happening with mammograms and other sorts of screening, where it's automated to make sure you're giving reminders to patients about things that they need to do for some of their basic health maintenance. But here, really providing important information – counseling that can be done by one of these chatbots in a way that is compassionate, informative and does not feel robotic to patients.   And then I was really impressed with, in the abstract on the screening colonoscopy, the ability of the AI instrument to really hear nuances in the patient's responses that could direct them directly to a care provider, to a clinician, if they thought that there might be some problem the patient was experiencing. So again, this could be something that could be useful in triaging phone calls that are coming in from patients or our portals that just feel like they are full of messages, no matter how hard you try to clear them all out, to get to them all. Could we begin to use AI to triage some of the more mundane questions that don't require a clinician to answer so that we can really focus on the things that are important, the things that are life threatening or severe, and make sure that we're getting to patients sooner? So there's just a few ways I really hope it'll help us. Dr. John Sweetenham: Yeah, absolutely. I think we're just scratching the surface. And interestingly enough, in my newsfeed this morning through email, I have an email that reads, “Should AI pick immunotherapy combinations?” So we'll see where that goes, and maybe one day it will. Who knows? Dr. Angela DeMichele There was a great study presented at ASCO about that very thing, and I think that is still early, but I could envision a situation where I could ask an AI instrument to tell me all of the data around something that I want to know about for a patient that could deliver all of the data to me in real time in the clinic to be able to help me make decisions, help me quote data to patients. I think in that way it could be very, very helpful. But it'll still need the physicians to be putting the data into context and thinking about how to apply it to the individual person. Dr. John Sweetenham: Absolutely, yes. And so just to round off, the final abstract that caught my eye, which I think kind of expands on a theme that we saw at an ASCO meeting two or three years ago around the impact of [oncology] care at home, and this was Abstract 1503 (“Acute care and overall survival results of a randomized trial of a virtual health intervention during routine cancer treatment”). So, a virtual platform but not AI in this case. And this was a study that looked at the use of an Integrative Medicine at Home virtual mind-body fitness program. And this was a platform that was used to look at hospital admission and acute care of patients who used it, and also looked at survival, interestingly enough. So what was done in this study was a small, randomized study which looked at the use of virtual live mind, body and fitness classes, and compared this in a randomized fashion to what they called enhanced usual care, which essentially consisted of giving the patients, making available to the patients, some pre-recorded online meditation resources that they could use. And this was applied to a number of patients with various malignancies, including melanoma, lung, gynecologic, head and neck cancers, all of whom were on systemic therapy and all of whom were reporting significant fatigue.  This was a small study; 128 patients were randomized in this study. And what was very interesting, to cut to the chase here, is that the patients who had the virtual mind-body program, compared with the control group, actually were less likely to be hospitalized, the difference there being 6.3% versus 19.1%, respectively. They spent fewer days in the hospital. And remarkably, the overall survival was 24.3 months median for patients in the usual care arm and wasn't reached in those patients who were on the virtual mind-body fitness class platform. So very preliminary data, certainly are going to need more confirmation, but another example of how it appears that many of these non-pharmacological interventions have the potential to improve meaningful endpoints, including hospital stays and, remarkably, even survival. So again, I think that that is very consistent with the theme of this year's meeting, and I found that particularly interesting, too.  I think our time is up, so I want to thank you, Dr. DeMichele, for sharing your insights with us today on the ASCO Daily News Podcast. We really appreciate it. And once again, I want to congratulate you on what was really a truly remarkable ASCO this year.  Dr. Angela DeMichele: Well, thanks so much for having me. It's been a tremendous pleasure to be with you today. Dr. John Sweetenham: And thank you to our listeners for joining us today.

Dr. Angela DeMichele, Dr. Lynn Henry, and Dr. Harold Burstein present the latest breast cancer rapid recommendation update impacting two ASCO guidelines. This update focuses on the new option, capivasertib plus fulvestrant, for patients with hormone receptor-positive, HER2-negative metastatic breast cancer with activating PIK3CA or AKT1 mutations or inactivating alterations in PTEN based on data from the recent CAPItello-291 trial. They discuss the updated recommendations on lines of endocrine treatment and selecting between the options for patients with activating PIK3CA mutations. Additionally, we discuss implications for clinicians and patients, and what ongoing research is occurring in the field. Read the latest update, “Endocrine and Targeted Therapy for Hormone Receptor-Positive, HER2-Negative Metastatic Breast Cancer – Capivasertib-Fulvestrant: ASCO Rapid Guideline Update“ at www.asco.org/breast-cancer-guidelines. TRANSCRIPT This guideline, clinical tools, and resources are available at www.asco.org/breast-cancer-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO.24.00248 Brittany Harvey: Hello, and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.   My name is Brittany Harvey, and today I am interviewing Dr. Harold Burstein from Dana-Farber Cancer Institute, Dr. Angela DeMichele from the University of Pennsylvania, and Dr. Lynn Henry from the University of Michigan, co-chairs on “Endocrine and Targeted Therapy for Hormone Receptor-Positive, HER2-Negative Metastatic Breast Cancer: Capivasertib–Fulvestrant: ASCO Rapid Guideline Update.” Thank you for being here, Dr. Burstein, Dr. DeMichele, and Dr. Henry. Dr. Harold Burstein: We're happy to be here.  Brittany Harvey: And before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including our guests on this episode today, are available online with the publication of the guideline update in the Journal of Clinical Oncology, which is linked in the show notes.  So then, to kick us off, Dr. Burstein, could you first describe what prompted this rapid update, which provides updated recommendations for two ASCO guidelines: the biomarkers for systemic therapy in metastatic breast cancer guideline, and the endocrine treatment and targeted therapy for hormone receptor-positive, HER2-negative metastatic breast cancer guideline? Dr. Harold Burstein: Thanks, Brittany. Well, this team has been working, as you mentioned, actually, on two guidelines, which are clearly evolving in parallel and kind of converging, actually, when you look at data, as we'll be talking about in the next few minutes. The particular catalyst here was a large randomized clinical trial which looked at a new targeted therapy in the space of estrogen receptor-positive, HER2-negative breast cancer. That drug is capivasertib. And the trial was the so-called CAPItello study. In that trial, patients who were receiving second-line therapy with fulvestrant were randomized to that treatment alone, or that plus capivasertib. So the data from that study were the first strong signal that we needed to update the guideline because they were important clinical data.   The other strong signal was that the drug was tested in a cohort of patients who had a specific set of mutations in their cancers. And that included PIK3CA mutations, a class of mutations for which we already had a targeted drug. But it also included some new potential targets, including mutations in the AKT gene itself, capivasertib is an AKT inhibitor, as well as loss of PTEN protein functionality, which potentially sensitizes tumors to the targeted action of this drug as well. So while we had a couple of guidelines catching up on the endocrine therapy space, which is increasingly looking like a targeted therapy space, it was clear that this major study, which had clinical and diagnostic implications, would sort of push them together and served as the impetus for updating both guidelines at the same time. Brittany Harvey: Understood. I appreciate that background information.   So then, Dr. DeMichele, based on this updated data that Dr. Burstein just described, what is the updated recommendation from the guideline panel regarding lines of endocrine treatment? Dr. Angela DeMichele: Well, I think this is where the biomarker evolution that Dr. Burstein just referred to really comes in because now we have the opportunity to perform genomic testing in patients who have ER-positive, HER2-negative metastatic breast cancer, on either the tumor or commonly from the blood. And we can now start to tailor treatment to the specific genomic abnormalities that that patient's tumor contains. So now our guideline really marries both the genomic abnormality with the therapeutic option. First-line treatment remains endocrine therapy plus a CDK 4/6 inhibitor. But things then really start to diverge once we enter second and third-line therapy because at that point, we now have the option to test for several genomic markers: ESR1 mutations, PIK3CA mutations, AKT1 mutations, and PTEN inactivation. And based on whether the tumor has one or any of those mutations, we can then select the therapy based on that.  So in the case of capivasertib, as you just heard, that is a therapy for patients whose tumors have PIK3CA mutations or activating mutations in AKT1 or loss of PTEN. But other patients who don't have one of those mutations may, in the second line, go on to another drug. For example, if they have an ESR1 mutation, they then may be eligible to take elacestrant. Patients who have no targetable mutations still have a targeted option in that they can use everolimus. And in all of these settings, the endocrine therapy partner for this line of therapy is typically fulvestrant. So now we're really starting to tailor therapy in the second- and third-line based on genomic changes. Brittany Harvey: Excellent. That information is helpful for choosing optimal therapy tailored to the individual patients, as you just described.  So then, Dr. Henry, what guidance does the expert panel provide regarding choosing a PIK3CA targeted option? Dr. Lynn Henry: Thank you. So for patients whose tumors are found to have an activating mutation in PIK3CA, we now have two drug options: either alpelisib or capivasertib in combination with fulvestrant. And the problem is, these drugs have not been compared head-to-head. We can't say that one is clearly better than the other, either in terms of efficacy or in terms of side effect profile. What we do have is information from two separate trials in which they were each tested against placebo. The efficacy appears to be fairly similar based on the data that we have. It does appear that the side effect profiles may be slightly different. And so, when you have a patient sitting in front of you and you're trying to decide how best to treat her, you really have to think about, what symptoms does my patient already have? What is she more or less likely to tolerate? So what we do know is that it appears that the rates of grade 3 diarrhea and rash were slightly higher with capivasertib. It looks like hyperglycemia was higher with alpelisib, as was treatment discontinuation. So really you have to make an individualized decision when you have a patient sitting in front of you about which drug you'd like to try. Of course, if someone doesn't tolerate one drug, you can always switch to the other one.  Brittany Harvey: I appreciate that analysis and to provide guidance without a head-to-head trial and to specifically provide options based on an individual patient's profile.   So then, Dr. DeMichele, what should clinicians know as they implement these new recommendations?  Dr. Angela DeMichele: Well, first of all, I think most clinicians now are becoming more familiar with the procedures required for doing genomic testing. But this is something that now has become the standard of care. And so, it is incumbent upon all of us who treat these patients to understand what the options for genomic testing are for that patient, which companies offer this testing, how to send a sample, and how to interpret the report that comes back. So, I think this has really added a level of complexity to the therapy for patients. I also think that one can't simply apply an algorithm to a patient. We have to really treat the whole patient and we have to take into consideration, as Dr. Henry said, the toxicities of these agents and the cost which is also a major issue. So I think that while it is more complex, really that doctor-patient relationship is so important in communicating what these genomic tests mean for a patient and for their options, and also important for the clinician to really understand what the different therapeutic agents might mean for a patient, and really try to pick the agent that's best for that patient. Using genomic testing is just one of several different features that they'll consider. Brittany Harvey: Absolutely. It's key to obtain the data needed to select appropriate patients and to recognize the complexity.   So then, Dr. Henry, in your view, how will this update impact patients with metastatic breast cancer? Dr. Lynn Henry: Yes, so as we've discussed, I think this is really exciting. Over the last few years, we have had quite a number of new medications that have become available for patients and have been FDA-approved. And so this is yet the latest in a series. For those patients whose tumors have a PIK3CA mutation, as we discussed, there are now two options. So you have a choice depending on which one is better covered by insurance, by which one you may tolerate better. But I think the other thing is now, although it's a smaller subset of patients, there are patients out there whose tumors have mutations in AKT1 or alterations in PTEN, and so there's an entirely new endocrine therapy-based option available for them that wasn't available before. So I think that thinking about the new data that are out there, the new drugs that are out there, really is exciting because there are new options available and hopefully there are more to come as well.    Brittany Harvey: Absolutely. It's great to have these new options.  So, finally, Dr. Burstein, Dr. Henry just mentioned what's to come. Could you touch on what some of the outstanding questions are regarding endocrine therapy for patients with metastatic breast cancer?  Dr. Harold Burstein: A couple of things to say. First, ER-positive metastatic breast cancer is the most common kind of metastatic breast cancer, roughly three quarters of metastatic cases of breast cancer will be hormone receptor-positive cancers. So this is a very big public health issue around the world, actually, breast cancer being the number one most commonly diagnosed cancer of women around the world. So minor or major improvements in treatment for advanced ER-positive breast cancer really have a tremendous impact.  The second thing is it's been remarkable to see the progress in the past decade. We've gone from simply targeting the hormonal access itself with medicines like tamoxifen or aromatase inhibitors or an injectable selective estrogen receptor degrader like fulvestrant to incorporating targeted therapies at the same time. And this whole class of drugs called CDK4/6 inhibitors has emerged which we use in either first- or in second-line therapy. Those drugs have transformed our standard of care, improved survival for patients with advanced ER-positive disease, now with median survival nearly 50% longer than what we had seen in the past.  And if you've heard, we have a wealth of opportunities. We can target PIK3CA, we can target ESR1 mutations. Other drugs emerging in the space include PROTACs which is another way of degrading the estrogen receptor. And so there's going to be more progress in the years to come.   So one of the biggest challenges has been to try and understand, is there really an optimal way to use these drugs, or can we be smarter about the particular sequence of all these particular things that are happening.  So one example of this was a recent study that is on a drug, not as yet FDA-approved, called inavolisib, which is a PIK3CA targeted drug used in first line in combination with a CDK4/6 inhibitor and endocrine therapy. And that study, for a high-risk group of women with ER-positive metastatic disease, actually showed a dramatic improvement in overall survival, asking the question if combining some of these targeted therapies together might yet further improve outcomes.  And as you've heard from the diagnostic space, one of the other interesting things is that tumors evolve over time. And so acquisition of the estrogen receptor mutations, ESR1 mutations, which are typically not found early in the course of advanced breast cancer but otherwise later, now have targeted treatments. So there's a whole bunch of stuff going on all at the same time, including multiple ways of targeting things, serial testing to look for acquisition of ESR1 mutations and new pathways to explore. It's an embarrassment of riches in some respects because it has meant it's actually really hard to write a guideline as you've heard, which says, “Do this first, do this second, and do this third.” I suppose that's a good problem to have under the circumstances, but it's going to require really thoughtful clinical trials and careful analysis to help guide specific lines of treatment recommendations like that.  Brittany Harvey: Excellent. We'll look forward to these exciting, continuing developments for patients with metastatic breast cancer. And I want to thank you all so much for your work to develop this rapid recommendation update for these two guidelines. And thank you for taking the time on this podcast today. Dr. Harold Burstein: Thanks. Dr. Lynn Henry: Thank you so much.  Brittany Harvey: And thank you to all of our listeners for tuning in to the ASCO Guidelines podcast.

Each October, BCRF-funded investigators are honored at the Foundation’s Symposium & Awards Luncheon in New York City. This year, the program was held virtually, without the lunch—but with all of the important conversations and ideas. The annual event announces the Foundation’s grant investment for the coming year and recognizes BCRF investigators for their trailblazing scientific inquiry. This year’s program included an extraordinary symposium, moderated by BCRF Scientific Director Dr. Judy Garber, that included Dr. Angela DeMichele, Dr. William G. Kaelin Jr. and Dr. Lori J. Pierce. We’re proud to make their discussion available in a special episode of Investigating Breast Cancer.

Dr Angela deMichele speaks with ecancertv at AACR 2016 about the results of the ISPY2 trial to determine new drug therapies for patients with HER2 positive breast cancer. From this arm, she reports significant improvement among patients receiving TDM1 with pertuzumab compared to current therapies. With this success in mind, she discusses the novel design of the ISPY2 trial, which accelerates patients towards more successful schemes to improve drug design and reduce toxicity, and its possible applications across the sector.

Dr Angela deMichele presents results at AACR 2016 from the ISPY2 trial, a novel trial design architecture to determine new drug therapies for patients with Her2 breast cancer, and to pair patients with the most effective possible treatment.
