  • Therapy for Stage IV NSCLC With Driver Alterations: ASCO Living Guideline Update 2025.1 Part 2
    Dr. Joshua Reuss joints that podcast to discuss the latest changes to the living guideline on stage IV NSCLC with driver alterations. He discusses the new evidence for NSCLC with EGFR mutations and NRG1 fusions and how this impacts the latest recommendations from the panel. He shares ongoing research that the panel will review in the future for further updates to this living guideline, and puts the updated recommendations into context for clinicians treating patients with stage IV NSCLC. Read the full living guideline update “Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2025.1” at www.asco.org/thoracic-cancer-guidelines TRANSCRIPT This guideline, clinical tools, and resources are available at www.asco.org/thoracic-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-25-01061 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'm interviewing Dr. Joshua Reuss from Georgetown University, co-chair on "Therapy for Stage IV Non–Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2025.1." It's great to have you here today, Dr. Reuss. Dr. Joshua Reuss: Thank you. Happy to be here. Brittany Harvey: And then 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 Dr. Reuss, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So to dive into what we're here today to talk about, Dr. Reuss, this living clinical practice guideline for systemic therapy for patients with stage IV non–small cell lung cancer with driver alterations is updated on an ongoing basis. So what prompted this latest update to the recommendations? Dr. Joshua Reuss: Yes, thank you. It's very important that we have living guidelines that are continuously updated. We obviously don't live in a static environment where things are non-changing, and we really need to apply the most up-to-date and current evidence to treat our patients with the most effective strategies, the most groundbreaking strategies. And so to have guidelines that can be disseminated, particularly these ASCO guidelines, to treating providers is incredibly important. So, with any of these updates, we review ongoing studies, published work, for the quality of evidence to see if it's something that warrants making adjustments to our guidelines or at least incorporating the information so that providers can review it and incorporate this into their own personal decision-making. So in this particular update, we reviewed evidence particularly pertaining to EGFR-mutated non–small cell lung cancer and non–small cell lung cancer harboring an NRG1 fusion. Brittany Harvey: Yes, certainly there's a lot of new evidence in the advanced non–small cell lung cancer field, and so we appreciate the panel's continuous review of this evidence. So then you just mentioned two separate areas where the panel reviewed new evidence. So starting with that first one, what updated evidence did the panel review on first-line treatment options for patients with EGFR alterations, and how did this impact the recommendations? Dr. Joshua Reuss: Yes, so advanced EGFR-mutated non–small cell lung cancer, at least with classical activating alterations - that is our exon 19 deletions and our exon 21 L858R mutations - is something that's really evolved rapidly in the last few years. You know, for many years, we basically, for the frontline treatment setting, were saying, "Okay, we have a targeted therapy, osimertinib. We're going to give that, and we're going to see what effect we can get out of that," with, you know, a median time of duration of treatment response averaging around 18 months, knowing that there are some that that's a lot longer and some that are a lot shorter. But recently, we've seen a lot of data emerging on combination strategies. The guideline has already been updated to incorporate two of these combinations: osimertinib with chemotherapy based off of the FLAURA2 trial, and then the combination of amivantamab with lazertinib based off of the MARIPOSA trial. And that was data on progression-free survival that was published and led to those particular recommendations. Now, more recently, we've seen data come out in smaller, randomized studies for other combinations. And more recently, we reviewed the RAMOSE study. So this was a phase II, open-label, randomized trial for patients with tyrosine kinase inhibitor–naive and really, treatment-naive advanced EGFR-mutated non–small cell lung cancer harboring one of these two classical EGFR alterations, randomized to either osimertinib alone or osimertinib with the combination of ramucirumab, which is an anti-VEGF agent. There's been a lot of data, preclinical and clinical, for the role of VEGF blockade, particularly in EGFR-mutated non–small cell lung cancer, so exploring the combination of this for synergy in the frontline setting really made a lot of sense. So again, this was a phase II trial that randomized patients prospectively to one of these two regimens. The population here is really what we typically see with EGFR-mutated non–small cell lung cancer, predominantly a younger population - median age on this study was 65 - predominantly female - 71% female - and predominantly nonsmokers. Now, what this study showed was that at a median follow-up of 16.6 months, the progression-free survival favored the combination arm with a median progression-free survival of 24.8 months with the combination of osimertinib plus ramucirumab versus 15.6 months for osimertinib alone, for a hazard ratio of benefit of 0.55. The landmark one- and two-year endpoints for progression-free survival also favored the combination arm, and response rates were relatively comparable between groups, with overall adverse events being more frequent in the combination group, specifically high blood pressure, proteinuria, and epistaxis, which are our common adverse events related to VEGF-blocking agents. So, it's good to see data in this space. Now, of note, though, this was a phase II study, so not a phase III level of evidence. In addition, when looking at the population, this was a randomized, multicenter study, but it was a US-only population. There was also some imbalance in the number of visits between arms, so the combination arm was seen more frequently than the arm that got osimertinib alone. Now, the imaging assessments were no different, but obviously this could lead to potential confounding, at least in timing of awareness of potential side effects and and things being brought to the attention of investigators. So very promising data here, but because, you know, of this being a phase II study, this actually led to no changes in the guideline at this time. Brittany Harvey: Understood. Yes, as you mentioned prior, it's important to understand the full body of evidence and to review the trials even when it doesn't impact the recommendations. Dr. Joshua Reuss: And I will say that, you know, there is an ongoing phase III study looking at a very similar combination. It's the phase III ECOG-ACRIN trial of the combination of osimertinib plus bevacizumab versus osimertinib alone in this specific population. So, you know, I think we will see phase III–level data for a combination of VEGF with osimertinib, but again, promising phase II data that did not lead to a change in the recommendation at this time. Brittany Harvey: Absolutely. We'll look forward to that ongoing trial to learn more about combination in this patient population. So then moving to that second patient population that you mentioned earlier where the panel reviewed evidence, what is the updated evidence and recommendation for patients with NRG1 fusions? Dr. Joshua Reuss: Yeah, so this was an exciting update that we made more recently with this unique iteration of the living guidelines. So, NRG1 fusions, this is perhaps a newer kid on the block in terms of driver alterations that has been known to be identified in non–small cell lung cancer among other solid tumors. It is very rare, occurring in less than 1% of solid tumors, but something that we know is a unique oncogenic pathway that can lead to oncogenesis and cancer development, including in non–small cell lung cancer. So up until now, unfortunately, there have not been targeted therapies that target this unique alteration. It's somewhat different than other driver alterations where there's a top-level signaling change in a protein. This is more of a ligand alteration that then alters, that then enables activation of more classical pathways, but again, through upregulation of a unique ligand. So a slightly different pathway but something that we know should be able to be targeted to promote patient survival for those with NRG1 fusions. So the therapy here is a therapy called zenocutuzumab. It's an IgG1 bispecific antibody against HER2 and HER3. So it prevents the downstream dimerization and signaling that occurs as a result of this NRG1 fusion and upregulation of the NRG1 signal. This was, as you can imagine with a rare alteration, a large phase II registrational study that examined this in advanced solid tumors containing the NRG1 fusion. This is the NRG1 registrational trial. And this study enrolled patients with advanced solid tumors who had progressed on prior therapy. Patients were treated with zenocutuzumab 750 milligrams IV every two weeks. Among 158 response-evaluable solid tumor patients, the response rate was 30%, median duration of response of 11.1 months, and a median progression-free survival of 6.8 months. Now, in those with non–small cell lung cancer, that made up 93 response-evaluable patients, very similar outcomes there: a response rate of 29%, median duration of response of 12.7 months, and a median progression-free survival of 6.8 months. This therapy did appear to be well tolerated. The most common higher-grade emergent side effects - grade 3 or higher - were anemia occurring in 5% and elevated liver numbers occurring in 3%. So this is a subsequent-line study, so this led to the updated recommendation that clinicians may offer zenocutuzumab in the subsequent-line setting for patients with advanced non–small cell lung cancer who harbor NRG1 fusions. So I think this does speak toward the incredible importance of next-generation sequencing and molecular testing for patients, particularly to include testing that looks at the RNA. These large fusions can sometimes be very challenging to detect on DNA sequencing platforms alone, so it's important to, if you have a high level of suspicion for an alteration like this, perhaps some of the mucinous adenocarcinomas where it's been challenging to find a driver alteration, and it's someone who is a never-smoker, really would want to include molecular testing that assesses the RNA level and not just the DNA. Brittany Harvey: Absolutely. It's important to have all the biomarkers available so that clinicians are able to use that to inform their decision-making. So then, given these changes in the guideline, what should clinicians know as they implement this latest living guideline update? And how do these changes impact patients? Dr. Joshua Reuss: Yeah, I think talking in reverse order of what we just discussed here, there is a new guideline update for NRG1 fusions. So I think making sure that that's being evaluated, that clinicians are testing for that and really looking for that result that should be incorporated in in most next-generation large sequencing assays to get that result, but it's very important that that is not overlooked now that we do have a therapy that's available in the subsequent-line setting, though it is important to note that patients with NRG1 fusions, at least the limited data that there is suggests that the efficacy to standard chemoimmunotherapy regimens is overall poor. So physicians unfortunately might be facing this question for second-line therapy in patients with NRG1 fusions sooner rather than later. For the former, for EGFR-altered non–small cell lung cancer and how do we incorporate VEGF-containing regimens into these patients? Our guideline top-level update did not change based off of review of this new study, but it's important for clinicians to know what other combinations may exist. You know, there are phase III studies looking at this combination in the frontline setting. And of course, there is data on other bispecific molecules that incorporate VEGF in the subsequent-line setting, particularly a combination that includes the VEGF/PD-1 bispecific antibody ivonescimab that's being studied in the HARMONi-A trial for patients with EGFR-mutated advanced non–small cell lung cancer, for which we hope to get some more definitive data in the coming months. Brittany Harvey: Definitely. And then you've just mentioned a few ongoing trials where we're looking for evidence to inform future updates. But thinking beyond that, into the future, what is the panel examining for future updates to this living guideline? Dr. Joshua Reuss: It's a very exciting time to be in the world of treating advanced non–small cell lung cancer, particularly patients with driver alterations, because there is so much evolving data that's changing our practice in real time, again highlighting the importance of these living guideline updates. I'd say there's many things that we're excited to see. You know, a lot of the combination regimens in EGFR-mutated non–small cell lung cancer for which there are approvals and current recommendations in our guideline, particularly osimertinib plus chemotherapy and amivantamab plus lazertinib - those are the two approved combination strategies in the front line - we are now seeing the emergence of overall survival data for those combinations. So obviously that is something that's going to be very important for the committee to review and incorporate into guideline updates. There are several new therapies coming down the road for other driver populations. We recently saw an approval for taletrectinib for ROS1 fusion–positive non–small cell lung cancer, so it's going to be important that the committee reviews the data and the publications regarding that therapy. And then there are other novel therapies that we're looking to see updated data on. There are multiple antibody-drug conjugates, which take the potent power of a chemotherapy molecule and attempt to make that targeted with an antibody targeting to a unique feature on the cancer cell. And there are several antibody-drug conjugates that are in development at various levels of promise in this space, particularly in EGFR-mutated non–small cell lung cancer, and I anticipate seeing some emerging data for that coming up in the near future as well. So really, lots to be excited in the space and lots for our committee to review to give guidance on so that these patients can really receive the top-level care wherever they are being treated in the country and throughout the world. Brittany Harvey: Yes, we'll await this new data to continue to provide optimal options for patients with stage IV non–small cell lung cancer with driver alterations. So, Dr. Reuss, I want to thank you so much for your work to rapidly and continuously update and review the evidence for this guideline and thank you for your time today.

  • Therapy for Stage IV NSCLC Without Driver Alterations: ASCO Living Guideline Update 2025.1 Part 1
    Dr. Lyudmila Bazhenova is back on the podcast to discuss the latest update of the living guideline on therapy for stage IV NSCLC without driver alterations. She shares the studies the Expert Panel reviewed in the first- and second-line settings, including NIPPON, HARMONi-2, and DUBLIN-3. Although these studies do not impact the existing guideline recommendations, Dr. Bazhenova provides context and comments on ongoing trials that will influence the next iteration of the living guideline. Read the full living guideline update “Therapy for Stage IV Non-Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2025.1” at www.asco.org/thoracic-cancer-guidelines TRANSCRIPT This guideline, clinical tools, and resources are available at www.asco.org/thoracic-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-25-01062 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'm interviewing Dr. Lyudmila Bazhenova from University of California San Diego Moores Cancer Center, co-chair on "Therapy for Stage IV Non–Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2025.1." It's great to have you back on the show today, Dr Bazhenova. Dr. Lyudmila Bazhenova: It's my pleasure to be here. Brittany Harvey: And then before we discuss this guideline update, 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 Dr. Bazhenova, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into the content here, Dr. Bazhenova, this living clinical practice guideline for systemic therapy for patients with stage IV non–small cell lung cancer without driver alterations is updated on an ongoing continuous basis. So what prompted this latest update to the recommendations? Dr. Lyudmila Bazhenova: Living ASCO guidelines are designed to keep pace with rapidly evolving evidence that impacts treatment of our patients with lung cancer. As a committee, we are tasked with regular review of the published literature and determine if the new data warrants changes to existing recommendations. So in this recently published update, we evaluated new trials related to treatment of patients with metastatic lung cancer without driver alterations. Brittany Harvey: Excellent. Thank you for that explanation of the process. So, you just mentioned that the panel reviewed new trials for this update. So, which particular updated evidence did the panel review on first-line treatment options for patients with good performance status across histology and PD-L1 expression status, and how did this impact the recommendations? Dr. Lyudmila Bazhenova: For the first-line treatment option for patients without driver alterations, two studies met our criteria for review. One was the NIPPON trial from Japan, the second was the HARMONi trial. None of those two trials resulted in change in our guidelines, but I think they are giving us some additional information that would be useful for the way we treat patients with non–small cell lung cancer without driver alterations. For example, if we take those patients, we currently have several treatment options as a first line. One is monotherapy immunotherapy. You can give pembrolizumab as an example, and that was based on the KEYNOTE-024 and KEYNOTE-042 trials. Then we have a platinum doublet plus immunotherapy, and there are several trials that did that pathway. And then we have also an option of giving our patients dual IO immunotherapy combination, such as CheckMate 9LA and POSEIDON. At this point, we do not have any randomized trials comparing those three treatment modalities head-to-head. And the NIPPON trial was interesting to us because it was the first trial to compare CheckMate 9LA regimen, which is again, dual immunotherapy plus chemo, versus KEYNOTE-189 or KEYNOTE-407, which is a chemotherapy plus immunotherapy. And as a result of the study, while chemotherapy plus ipilimumab-nivolumab led to numerically higher overall survival, the difference was not statistically significant. And what is concerning in that trial is that we saw a higher number of treatment-related death occurring in nivolumab and ipilimumab arm compared to the pembrolizumab-chemotherapy arm. As a matter of fact, the trial was terminated early because of the increased risk of death. If you look at the treatment-related death in CheckMate 9LA, the 9LA study reported the treatment-related death to be 2%, and then in the NIPPON trial, the treatment-related death was 7%. Why is that happening? It's really difficult to say. The study was done in Japan. Maybe there is some pharmacogenomic differences between global population and Japan population. But certainly the higher rate of adverse events needs to be taken into account. Another interesting thing about this trial is that it did not show any differences in a subset analysis for patients with squamous histology as well as PD-L1 negative tumor. So while this does not change our current guidelines and CheckMate 9LA treatment still remains an appropriate treatment option, it kind of raises the possibility that this combination could be associated with a higher toxicity. And we do have a randomized US-based trial that is ongoing, and we are hoping that eventually we will be able to answer that question after the trial will be completed. The second trial we reviewed is HARMONi-2. So HARMONi-2 was a randomized, double-blind study which is conducted primarily in China, looking at bispecific PD-L1 and VEGF antibody called ivonescimab. And that took patients who were PD-L1 positive, as defined as more than 1% expression, and patients were randomized to pembrolizumab versus bispecific ivonescimab. And the study was positive. It showed improvement in median progression-free survival of 11 months versus almost 6 months in bispecific versus pembrolizumab. There were, however, higher grade 3 events in the ivonescimab arm. At this point, we are not changing our recommendations because this trial was done in an ex-US population, and we are awaiting a similar trial ongoing in the United States before we change recommendations and decide if ivonescimab needs to be included in our guidelines. Brittany Harvey: This context is very helpful when clinicians think through the data behind these options. And it's important that the panel reviews this evidence, even if it doesn't prompt a change to the recommendations. And we'll await results of those trials that you mentioned to further inform this guideline. So then beyond those studies for first line, what updated evidence did the panel review for second-line and subsequent treatment options for patients with good performance status, and how did this impact the recommendations? Dr. Lyudmila Bazhenova: So for second line, only one trial met the criteria, and that was DUBLIN-3. DUBLIN-3 is a phase 3 single-blind randomized trial comparing docetaxel versus docetaxel plus plinabulin. And the study enrolled patients with second or third line. They have to have had platinum-based chemotherapy and progressed. Plinabulin is an interesting compound. It's a small molecule tubulin binder that prevents polymerization of tubulin and appears to impact dendritic cell maturation and T-cell activation. This study enrolled 559 patients, randomly assigned them to two groups. And one important information about this study is that was a study that was envisioned before immunotherapy became a standard mainstream treatment for first-line therapy. And only 20% of patients had prior PD-1 exposure. So therefore, the results of that study need to be taken into context of this population no longer existing in the United States because we use PD-L1 inhibitors in the first line. And we saw that interesting in the plinabulin arm had lower rates of neutropenia but higher rates of serious adverse events. And at this point, we are not changing our guidelines for mainly two reasons. Number one, low number of patients that received prior treatment with first-line immune checkpoint inhibitors, as well as a modest overall survival benefit of this trial. Brittany Harvey: Understood. I appreciate you describing that study as well and why that evidence didn't prompt a change to those particular recommendations. So then, what should clinicians know as they implement this living guideline, and how does this new evidence impact clinicians and patients? Dr. Lyudmila Bazhenova: At this point, none of the studies that we reviewed resulted in a change in guidelines. We are still waiting for more global results from some of the studies that I highlighted. It shows that there's still a lot of questions we need to be answering in those patients. And I'm hoping that with future clinical trials, we will be able to definitively maybe recommend one treatment over another. But at this point, all the treatments that I mentioned before remain appropriate for patients with stage IV non–small cell lung cancer without driver alterations. Brittany Harvey: Definitely. And then you just mentioned that there's still a lot of outstanding questions in this field. You've mentioned a couple different studies where we're awaiting evidence. Beyond those that you already mentioned, what is the panel examining for future updates to this living guideline? Dr. Lyudmila Bazhenova: Right now, our next task is to come up with a full guidelines update. ASCO have certain rules for the guidelines committee members. And so we are gearing for a full guideline update, which hopefully will be ready by the end of 2025. Brittany Harvey: Excellent. We'll look forward to that full update of the living guideline, and we'll still await results of these ongoing trials to further inform this living guideline. So I want to thank you so much for your work to rapidly and continuously update this living guideline, and thank you for the time today, Dr. Bazhenova. Dr. Lyudmila Bazhenova: My pleasure. Brittany Harvey: And finally, thank you to all of our listeners for tuning in to the ASCO Guidelines podcast. To read the full guideline, go to www.asco.org/thoracic-cancer-guidelines.

  • Medically Integrated Dispensing Pharmacy: ASCO-NCODA Standards Update
    Dr. Luis Raez and Michael Reff share the newest update to the medically integrated dispensing pharmacy standards from NCODA and ASCO. They review updates to domain one, on key patient-centered quality standards on health equity and social determinants of health, drug access, patient safety, education, and adherence to maximize treatment outcomes and domain two, on key operational quality standards on logistics, care coordination, and waste prevention. We also cover the impact of these updated standards for clinicians, oncology practices, and people receiving oral anti-cancer medications. Read the complete standards, “Medically Integrated Dispensing Pharmacy: ASCO-NCODA Standards.” Transcript These standards, clinical tools, and resources are available on ASCO.org.  Read the full text of the guideline and review authors’ disclosures of potential conflicts of interest in the JCO Oncology Practice. 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'm interviewing Michael Reff from the Network of Collaborative Oncology Development and Advancement and Dr. Luis Raez from Memorial Cancer Institute and Florida Atlantic University, co-chairs on "Medically Integrated Dispensing Pharmacy: American Society of Clinical Oncology – Network of Collaborative Oncology Development and Advancement Association Standards Update." Thank you for being here, Michael and Dr. Raez. Dr. Luis Raez: Thanks for inviting us. Michael Reff: Thank you for having us. Brittany Harvey: Then, before we discuss these standards, I'd like to note that ASCO takes great care in the development of its standards and ensuring that the ASCO Conflict of Interest policy is followed for each guidance product. The disclosures of potential conflicts of interest for the expert panel, including Michael and Dr. Luis Raez who have joined us here today, are available online with the publication of the standards in JCO Oncology Practice, which is linked in the show notes. So then, to dive into the content here, Michael, I'd like to start with what prompted an update to these ASCO-NCODA standards and what is the scope of this update? Michael Reff: Thank you, Brittany. What led NCODA and ASCO to endeavor in this, and it started back in 2019 as the amount of oral anticancer medications became more and more prevalent in cancer treatment, we saw the need providing a blueprint for excellence in care for patients prescribed oral anticancer medications, specifically in the outpatient setting. And the update was driven by the rapid growth of these oral oncolytics starting back in the mid to late 2015 through 2019 or so, and then continued on into the 2020s where we are today. We saw the increase in the complexity of the management of these patients with these therapies basically outside the traditional clinical settings. And we wanted to make sure that with more cancer treatments that are taken at home than just at the clinic, like in the oral setting, new challenges had emerged around patient safety, access, adherence, and overall treatment success. The updates now address patient-centered and operational interventions designed to improve access, safety, quality, accountability, and outcomes of oral anticancer and other supportive care medications prescribed for the cancer patient. Dr. Luis Raez: As Mike said, these guidelines help improve patient care tremendously, but also help us a lot as an oncologist, you know, community oncologists that- now that we have opportunity to dispense these oral oncolytics, we need help to create our medical integrated pharmacies, and NCODA is providing here a way that, how to do this safely, efficaciously, good quality, you know? So that's why I think we always do everything for the patients, but also this helps a lot to the doctors. And there are a lot of what we call specialty pharmacies or medical integrated pharmacies now nationwide. Michael Reff: I'll build on what Dr. Raez had mentioned. This is the impetus. If you looked at the innovation that was coming from the pharmaceutical companies, many of it coming in the oral form for anticancer medications, and based on that, taking a look at the infrastructure that is in place in these practices, whether it's in the community or the IDN or health system settings, this amount of innovation that was coming needed to be addressed by taking a look at the medically integrated oncology team. And these standards address not just the pharmacy component, but also the whole continuum of care, starting with a medical oncologist or the hematologist, with the pharmacists, nurses, the pharmacy technicians, others that are involved in the care of the patient. And there were no standards involved. And when we approached ASCO back in 2018 to eventually publish the first version of these standards, the need was identified, and we worked collaboratively with ASCO to create the first set and then the revisions as we talked about. One thing to note regarding the revision plus the original standards, we had a cross-section of the care team on the committee, and we did that very purposefully. So, the ASCO-NCODA team curated a committee to help develop these original standards and the revision of these standards with medical oncologists both from community and health systems, pharmacists from both community and health systems, and also nurses. And we also included a patient that currently has and currently receives oral anticancer medication. And so NCODA and ASCO are very proud of the committee that we put together because of the experts in their field, but also extended the invitation to a current patient. And we embedded everybody's expertise in the curation of these standards. Brittany Harvey: Absolutely. I appreciate that background and context and how it's critical to improve patient care. And these standards really help oncologists, and we're looking across the continuum of care to provide optimal care for our patients. So then next, Dr. Raez, I'd like to review the key points of the revised standards for our listeners. So for Domain 1, what are the key patient-centered quality standards on health equity and social determinants of health, drug access, patient safety, education, and adherence to maximize treatment outcomes? Dr. Luis Raez: Yeah, this was a great effort, you know, at the multidisciplinary team. And as you can read in the standard, there were more than 240 publications reviewed; more than 55 of them are quoted here. And the standards are in two groups, as you said. With the group one, I'll briefly mention some of them. For example, SDOH, social determinants of health, is very important because as doctors, we prescribe, and sometimes patients don't get the medication, you know? And we prescribe assuming that 100% of the patients will get the medication. But something simple like the patient doesn't have insurance, the patient is underinsured. I have a patient that we didn't have an address to send the medication because he's homeless. Something that as a doctor you say, "Oh, oh my God, this is outside my realm," but it's not outside reality. So that's why, even if we don't think that this is part of our expertise dealing with social determinants of health, the fact that the patients have food insecurity, they don't have transportation, they don't have insurance, they don't have a caregiver, impact tremendously in the outcomes of the therapy. So that's why, basically, in this standard, we want to call attention that SDOH, social determinants of health, needs to be identified. There are in the literature countless examples of why this is important. For example, in the guidelines, we quote two or three examples of prostate cancer studies that, for example, we quote a study of 27,000 people with prostate cancer that were taking oral oncolytics, and how come the fact that the elderly, seniors, the fact that they have high prescription costs, and how all of this affected the adherence to the medication. And that's why it's important to identify the SDOH. And in other sections of the guidelines, we said how to address them, no? Another important thing in this domain is the cultural, you know, we need to be culturally sensitive and to take care of all of these social factors. For example, here in South Florida, we deal with the Haitian culture, Filipino culture, Latin culture, and American culture, and it's a blend, but it's not easy to go from one to the other. Another one is the fact that we have to include new technologies. A lot of patients, for example, we use EMR, EMR Epic, and now Epic has everything in the phone. The fact that we can have now the patient can see her prescription medication over the phone, the fact that they can use the phone to request from you a refill, and from your phone, you send the refill to the pharmacy, and you notify from your phone to the patient that the refill is sent, and the patient can check in his phone that the refill is ready. These things are amazing because that's why it's important that we incorporate these technologies to the patient care, and in this specific case, of dispensation of oral therapies, no? Another crucial point is education. You cannot be sending a patient a package of 300 pills without education. So that's why in our guidelines, mainly pharmacy, clinical pharmacies, or in some centers like mine, we have advanced practice providers, it's mandatory in our centers to have like a one hour of education before you send the prescription. So the patient is aware about side effects and contraindications, all of these things. They provide them also materials and also consent. You know, in the old times, you don't give chemo without a consent. Now, a lot of people say, "Oh, it's only a pill." There is a lot of benefits or side effects that can come from the pill, so you need to consent everybody, you know? So, another aspect is adherence. I already told about that, but we need to provide patients with a baseline assessment, no? So, you cannot send again the prescription and hope, "Oh, I'll figure it out what happened next month when the patient comes back." I tell you, the patient is homeless, where are you going to send it? If the patient is telling you, "I don't have insurance," what good is it for you to send a prescription? The patient will not get it. So that's why you need to do a baseline assessment of adherence. You need to do a calendar. You need to do electronic support, I mentioned already with the EMR and the phones. For example, my MIP, my specialty pharmacist, sends me a message in the EMR, "Dr. Raez, the insurance is not covering, the patient has a high copayment, we are going to delay the dispensation of the medication." So there needs to be a communication. Or sometimes there is a confusion with the insurance, and I cannot wait for the poor patient to call three, four weeks later, "Oh, I didn't get the medication," to know what happened, no? My MIP is very good. They send the clinical pharmacist a message, "Hey, you know, the insurance doesn't believe that the pill is adequate, or you need to provide more documentation. You need to prove the mutation, the genetic aberration." So if you provide us that, the insurance may approve. So that communication with the doctor is very important to improve adherence. And one important thing that we have in this one that we didn't have in the anterior is the tracking of outside medications. A lot of times you say, "Okay, the insurance allowed us to provide the medication it’s 100% responsible." But then the insurance says, "Oh, no, no, don't worry. CVS will provide the medication." So it says, "Well, it's you know, it's not my responsibility. CVS will provide the medication, they have to take care." But we know that outside our specialty pharmacies or MIPs, the care is not very good. So that's why we are taking our ownership that, "Okay, the insurance said the patient will get the medication from some outside pharmacy." But our clinical pharmacists track that. What happened? Did the patient get it? The patient didn't get it. The copayment is still high. So even if you get the medication from somewhere else, if the copayment is high, we, our clinical pharmacists, help the patient to navigate and get the foundation or the copayment or finally the maker, the industry partner, provides the drug for free, but somebody needs to do the paperwork. And that's why this is very important. We cannot abort our responsibility because, "Oh, the insurance said somebody else will give it." I work for the public healthcare system, so my patients, some of them don't have insurance, they are underinsured. So we see these problems every day. And finally, the standards talk about the importance of safety, documentation, verification, monitoring, refills, you know, you need to keep track of refills. We already mentioned how important is the technology to facilitate the refills, and the quality. Brittany Harvey: Yes, thank you for touching on those highlights for Domain 1. It's important that all patients have access to care and these oral anticancer medications, and not only just access to care, but safe and effective care. It's really important, as you mentioned, Dr. Raez, to meet patients where they're at and incorporate technology. And I also want to note the coordination with external pharmacies that you mentioned in tracking outside medications as well. It's not only important for multidisciplinary care within the oncology practice itself, but also external to the oncology practice. That's why we put together this multidisciplinary panel to develop these standards. So then, expanding on that, Dr. Raez, for Domain 2, what are the key operational quality standards? Those on logistics, care coordination, and waste prevention. Dr. Luis Raez: Yeah, we have a lot of standards here, but maybe we can summarize in five or six points, no? For example, financial toxicity in cost and waste are very important because the patients, yeah, you put them on therapy, but as you can understand, if there is disease progression, the patient don't need the medications. And sometimes you get refills even if the patient has disease progression. If you do a dose reduction, the same problem. Or you discontinue medication and the patient keeps getting the drugs. So, you're talking about drugs that are between 20 and 30 thousand dollars per month. This is a lot of money. There are studies that we're quoting in the standards that the waste could be from 1 to 3 or 4 thousand per patient, no? Another aspect is dispensing. When you dispense the medication, this is not as easy as, "I'll ship to your house a bag of medications." You know, there needs to be a diagram, a decision tree. You need to train the staff to know what we're doing. There needs to be an auditing of the process. They need to be even packaging and shipping, you know? For example, I'm in Florida today and outside in summer it's going to be 95 degrees. So, everybody leaves the package outside your house, and sometimes you go the whole day until when you come at 6:00 p.m. There are medications that cannot be left outside there, you know? I don't know, it sounds like a joke, but I have a patient that the medication used to be stolen because people thought that that was something important, you know? And of course, it's important because it's a $20,000 medication. So, the poor patient, because he lives in an area that is not safe, has to come and pick up in person. All of these things sound very trivial, but that's real life that affects adherence. Another important thing is shortage. This is something that we just suffered two or three years ago, and we have to think about what happens in the next shortage. What happens if there's going to be a shortage? What do we do or how are we going to do that? Now we know it's something that is happening probably very soon again, and something that we have to consider. Another standard is the care coordination. You need to have probably, if it's possible, a coordinator. I know that for small practices it's very hard, but for big cancer centers, you should have a coordinator of this. I already mentioned before, the communication between the physicians and the doctors to coordinate the care, no? You need to write the prescription again, you need to provide more information, or to be notified, "Hey, you know, the patient is throwing up in the first week, you need to see the patient, please," no? So, this type of communication needs to exist so we can serve the patient better. It's also important, you know, we're improving quality and we're improving care. It's important to try to collect patient-reported outcomes. This is something that now we have the opportunity, if we do things well, to do it and show that we're providing a better care. The other thing is that we already mentioned SDOH in the other standard. In this standard, we mention mainly SDOH to partner. For example, we collect in my center SDOH, and I always get frustrated when the patient doesn't have transportation. But I didn't know that there are local institutions that provide free Uber rides, free Lyft rides. So that's why it's important to partner with these institutions. I have a local grocery chain that provides free food for the patients, and I didn't know that. It's important to be aware what the patient needs and what resources do you have to fulfill the SDOH. That's the part that we mention in here. So that's why, in summary, those are the six probably most important points here. I'll ask Mike for some comments. Michael Reff: Thank you, Dr. Raez. Brittany, to answer your question, and as was pointed out on logistics, care coordination, and prevention of waste, certainly that is an aspect that has changed in the revision that we're here to talk about. There's really two components to waste, and it's cost avoidance and then waste prevention. And as Dr. Raez mentioned several times, the importance of the medically integrated team and having the ability for that practice to fill that prescription internally and have robust documentation. Cost avoidance is a critical component that the medically integrated pharmacy, or the MIP, can help the total cost of care. And that is by preventing errant fills or waste that can occur by intervening in the care of the cancer patient, as we do every day. But when the practice has access to the medication and can fill that prescription in-house in the medically integrated pharmacy, that team, that care coordination that takes place, can prevent those errant fills or additional fills when there's dose reductions, there's holidays, there's things that happen in real time. And it's impossible for a mail-order pharmacy that's in another state that has lead times, when a prescription needs to be mailed 7 days or 10 days before the patient will run out of the medication, it's impossible for them to logistically coordinate that care like we can internally within the medically integrated pharmacy. So, we prevent waste and overall cost of care by cost avoidance and having that coordination or that continuity of care that we talk about. And we prevent waste from the mail-order pharmacies by taking that prescription internally and filling it, but also doing it in a way that's more sustainable and cost-effective for all stakeholders in the oncology ecosystem. Brittany Harvey: Absolutely. Thank you both for reviewing those key standards for Domain 2 and touching on the importance of distribution logistics and all the things that a medically integrated pharmacy needs to think through in getting oral anticancer agents to patients. Following that, Michael, we've touched on this a little bit earlier, but how will these updated standards impact clinicians and oncology practices? Michael Reff: Yes, and as Dr. Raez and I have discussed throughout this podcast, these additional standards are there to help support that continuity of care by educating the clinicians that are in the oral anticancer medication space to elevate their provision for these oral therapies. What I mean by that is the practice has to perform at a certain level in order for them to, as I call it, deserve the right to fill that prescription by having the processes and procedures in place. And these standards, these updated or revised standards, are the blueprint for better patient care and to help the practices execute on that journey of continuous improvement. Dr. Luis Raez: Yeah, I only want to add, we have practical examples in the guidelines. We quote a couple of studies that have been successful. And this year, for example, I am a lung cancer doctor, we are presenting in World Lung our standards of adherence to oral oncolytics for EGFR therapy, following the NCODA-ASCO standards. We're around 95% of adherence. We are a healthcare system that is public. We have people with no insurance and a lot of social determinants of health. We are trying to show that it's feasible, even in the most difficult circumstance, when you follow the standards, to be successful. Brittany Harvey: Definitely, these standards can help clinicians and oncology practices succeed in providing these medications. So then beyond that, and to wrap us up, Michael, what do these revised standards mean for patients who are receiving oral anticancer medications? Michael Reff: Yes, great point and question, Brittany, because we have covered the benefits to the clinicians and the practices themselves. But how is this going to support better patient care? And it does it in a whole host of ways. I'll cover just a few of them. What I'm about to share with you relates back to what we call at NCODA the "core claims." Like, what's the core claims of having a medically integrated pharmacy within the practice? And there are seven different core claims that we feel practices that are focused on the continuity of care can deliver better outcomes that are embedded in these standards. And it's talking about abandonment, adherence, access and affordability, speed to therapy or time to fill, as we call it, education, patient satisfaction, and cost avoidance that we covered earlier. So those are the core claims that a practice that follows these revised standards can help elevate. So, faster and more affordable access to the oral cancer medications; individualized support to address barriers like transportation, finance, language, or health literacy, and so on; clear, patient-friendly education; something that is near and dear to all clinicians' hearts, and of course, the patient that was on our panel or on our committee, to empower them to manage side effects and recognize when to seek help; and a stronger partnership with a care team, with regular follow-ups focused on their experience, challenges, and successes; and then, greater overall safety through proactive monitoring for medication errors or complications. So all of these aspects, or tenets, as I'll call them, are baked into these quality standards that are totally aligned with NCODA's core claims document that, again, talks about abandonment, adherence, access and affordability, speed to therapy, education, satisfaction for the patients, and also cost avoidance. Dr. Luis Raez: I only want to add and invite the community to adhere to these standards, to practice the standards. You will be providing the best patient care that we can nowadays. Brittany Harvey: Definitely. I think these standards are very important. And Michael, I thank you for touching on those key claims from NCODA. I think those, along with these updated standards, will improve outcomes for patients everywhere. So I want to thank you both so much for your work to update these standards and all the time you put into it. And thank you for your time today too, Michael and Dr. Raez. Michael Reff: I'd like to thank not only the committee, my esteemed committee that helped support the standards and the revision. Many of the original healthcare providers and patient that were on the first go of the standards were part of the second standards. We revised it, of course, and we got additional support from the new committee. And certainly ASCO and their partnership and collaboration with NCODA has been tremendous. And we look forward to the oncology community at large adopting these standards, again, to work together, we do become stronger, and it will improve cancer care for patients receiving oral anticancer medications. So thank you, Brittany. Dr. Luis Raez: I only want to say the same thing. Actually, there is probably more people in NCODA that is not in the publication that has helped. Same in ASCO. Also, we want to give thanks to Dr. Stephen Grubbs, our leader in quality. He's retiring. We're going to miss him, but he has been a key collaborator with Mike organizing these standards for the last five or six years. So, looking forward to these standards in practice. Brittany Harvey: Absolutely. A big thank you to the entire panel and everyone who contributed to this, and NCODA as well.

  • Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors Guideline
    Dr. Kimberly Perez and Dr. Jaydira Del Rivero discuss the new guideline from ASCO on symptom management for well-differentiated GEP-NETs. They share the latest recommendations on managing symptoms related to hormone excess, including carcinoid syndrome and carcinoid heart disease, managing symptoms of functioning pancreatic neuroendocrine tumors, and also palliative interventions. Dr. Perez and Del Rivero share how to use this guideline in concert with the systemic therapy for tumor control in metastatic well-differentiated GEP-NETs guideline, and hope for the future for the treatment of gastroenteropancreatic neuroendocrine tumors. Read the full guideline, “Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline.” Transcript This guideline, clinical tools, and resources are available on ASCO.org. Read the full text of the guideline and review authors’ disclosures of potential conflicts of interest in JCO Oncology Practice.        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'm interviewing Dr. Kim Perez from Dana-Farber Cancer Institute and Dr. Jaydira Del Rivero from the Center for Cancer Research at the National Cancer Institute, co-chairs on “Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline.” Thank you for being here today, Dr. Del Rivero and Dr. Perez. Dr. Kim Perez: Thank you. Dr. Jaydira Del Rivero: Thank you so much for the invitation. Brittany Harvey: And then 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 Dr. Perez and Dr. Del Rivero, who have joined us here today, are available online with the publication of the guideline in JCO Oncology Practice, which is linked in the show notes. So then to jump into the content here, first Dr. Del Rivero, could you provide an overview of the scope and purpose of this guideline? Dr. Jaydira Del Rivero: Yeah. Thank you so much. Well, first, we really wanted to thank ASCO for allowing us to develop these guidelines for the management of gastroenteropancreatic neuroendocrine tumors. I do want to mention that there is also another set of guidelines that I was very fortunate also to co-chair with Dr. Perez on the systemic management of gastroenteropancreatic neuroendocrine tumors. But when discussing these guidelines as well as with the different panelists, experts in this type of disease, we also realized that the management of these tumors are quite complex, not only from the management of the disease progression, but at the same time, management of the symptoms related to the hormone excess. And because of that, we like to thank ASCO for allowing us to then not only have a discussion on the systemic management of these tumors, but at the same time develop recommendations for the symptoms related to the different hormones that these neuroendocrine tumors may produce. These guidelines are for the management of grade 1 to grade 3 metastatic gastroenteropancreatic neuroendocrine tumors. These guidelines include the management of the different aspects and the symptoms related to hormone excess, such as carcinoid syndrome, carcinoid heart disease, how to manage carcinoid crisis, as well as the different symptoms and how to manage the functional pancreatic neuroendocrine tumors and as well as provide recommendations in the different treatments for these tumor types, not only from the systemic management but also from the surgical management as well as for liver-directed therapy options and the different aspects in terms of the palliative care of these patients to improve not only the symptoms related to the hormone excess caused by these tumors, but as well as to improve the quality of life. Brittany Harvey: Absolutely. And I appreciate that overview. And yes, we'll link the guideline on the Systemic Therapy for Tumor Control for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors in the show notes for our listeners so that they can refer to that companion guideline as well. So then you just described the several different categories of recommendations that this guideline covers on symptom management. So, Dr. Perez, I'd like to start reviewing some of those key recommendations of that guideline. So, starting with what are the key recommendations for carcinoid syndrome and carcinoid heart disease? Dr. Kim Perez: Thank you Brittany. Yeah, I also want to thank ASCO for inviting us to do this podcast today. Just to start, I think these guidelines will really add to what's available in the literature to provide a kind of a quick look for the community provider to manage carcinoid-related symptoms. I think the highlights that I would point out are we've all been using somatostatin analogs for the last few decades to manage symptoms, but with the newer treatments that are now available, we tried to highlight what does the literature support in regards to PRRT, what does the literature support in regards to using systemic therapy for disease management, but also the benefits that you will get from a symptom management perspective using other modalities. I think the highlight really is it's a multidisciplinary approach. We are now considering surgery and embolization or interventional radiology as a critical piece. And I think the third that I'd highlight is the fact that sometimes we get too focused on carcinoid syndrome and the symptoms will actually, may result from other things. And the highlight in the algorithms that we've provided is what other things cause carcinoid-related diarrhea. And let's not forget about that because we will find ourselves treating and patients getting very frustrated with persistence of symptoms when in actuality, we should be treating something else that is causing a very similar symptom. For carcinoid heart disease, I think there are more and more guidelines that are now available to provide guidance there, but I think the major advances are that we should be utilizing heart assessment with echocardiogram with lab values such as BMP. But also critical to this is consulting with our cardiology colleagues and making sure that we're identifying heart related issues that are resulting from hormone excess sooner than later because interventions on the earlier side can really make a significant impact on quality of life and associated comorbidities and mortality. Brittany Harvey: Thank you for reviewing those key points for both carcinoid syndrome and carcinoid heart disease symptom management. So then the next set of recommendations. Dr. Del Rivero, what are the key highlights for symptom management of functioning pancreatic neuroendocrine tumors? Dr. Jaydira Del Rivero: Yes, it's very important to recognize the symptoms related to hormone excess due to pancreas neuroendocrine tumors. Up to 10% of pancreas neuroendocrine tumors may produce different hormones. Among those hormones can be insulin, gastrin, glucagon, somatostatin. So it's important to know and understand that based on what a neuroendocrine tumor is, they may produce different types of hormones. The importance of these guidelines is to also recognize some of these symptoms and how to address that, because it's not necessarily in these tumor types besides the management of metastatic disease, and know the different options that we recommend for metastatic disease from the systemic therapy, such as chemotherapy or targeted therapies or PRRT. It's important to recognize the symptoms because based on the symptoms we may recommend a different approach. That's something that is important to acknowledge and recognize. Moreover, in certain functional pancreas neuroendocrine tumors, as Dr. Perez mentioned, is a multidisciplinary approach. And it's important to also discuss these different cases with your endocrinologist. You may need to have an experienced endocrinologist to manage, for example, the excess of insulin. And also discuss your cases with a surgeon and interventional radiologist because some of these approaches can certainly improve the symptoms related to hormone excess. I understand that sometimes medical oncologists in the communities may not have access to the multidisciplinary approach or have the different teams that can manage these tumors, and that's the reason why with these guidelines we wanted to establish the understanding of different symptoms associated with the hormone excess to these neuroendocrine tumors as well as how to manage this. For example, in the case of insulinoma, I think for the medical oncologist it is important to know that the everolimus is an option to be used for these tumors, not only to manage tumor progressions related to this tumor type at the same time, because everolimus as a side effect causes hyperglycemia, that can also improve some of the symptoms related to the excess of insulin besides the somatostatin agonist. I think these recommendations will allow the medical oncologist to recognize the symptoms and based on what the symptoms cause, then you can have a different approach that could be added to the systemic therapies options as well. Brittany Harvey: Yes, beyond systemic therapy, it's important to be recognizing symptoms to provide an individualized approach for every single patient. So then, following that overview of symptom management for functioning pancreatic neuroendocrine tumors, Dr. Perez, what is recommended regarding palliative interventions for patients with gastroenteropancreatic neuroendocrine tumors? Dr. Kim Perez: Yeah, great question. So I think what's unique to neuroendocrine tumors is that the palliative approach really mirrors what we would be doing for symptom management. Some of these patients are living a very long time with carcinoid related symptoms. And so the approach that we take for the carcinoid symptom control is going to mirror the palliative piece of it. I think for those who develop a burden of disease related symptoms, I think it mirrors what we do across the board for all cancer-related complications. And so I think what we attempted to highlight here and included one of our colleagues who focuses specifically on the field of palliative care and neuroendocrine tumors, was to never really lose sight of what we've been doing to care for symptom management throughout the patient's journey and to always rereview the etiology of the symptoms, ensure that we don't focus solely on carcinoid-related issues, but also the symptom management that we would apply to all patients with cancer-related burden symptoms. Brittany Harvey: Definitely. I think that's a helpful approach to consider when thinking about how to manage these palliative interventions as well. So then Dr. Del Rivero, what should clinicians know as they implement these symptom management recommendations? Dr. Jaydira Del Rivero: Yes, thank you so much for that question. As we have discussed in the last 10 or 15 minutes, we have discussed the different approaches on the management of gastroenteropancreatic neuroendocrine tumors. Clinicians, I think it's important to know that neuroendocrine tumors is a quite complex disease because we're not only addressing the management of tumor growth, but we're also addressing the management of the symptoms related to hormone excess and the complexity associated with that. When medical oncologists or clinicians implement these recommendations it’s to understand what symptoms these tumors may cause related to the hormone excess but at the same time, how do we approach those symptoms? As Dr. Perez said that I think is very important is to recognize the different types of diarrhea. It doesn't mean that if the patient has worsening diarrhea, it doesn't mean that this is related to disease progression. So it's important to recognize so that way you can address that, because the type of diarrheas can be related because of the lanreotide or somatostatin agonist, it could be because of the prior surgery. I think it's important to recognize those in order to address the symptom. And the same with the gastroenteropancreatic neuroendocrine tumors. It's important to know what hormones they produce because there are different measurements that may be added to the systemic management of these tumors. I think that there are two aspects here, and that's the reason why these guidelines were implemented in the sense that not only we're going to manage disease progression of these tumors, or how do we manage the metastatic disease of these tumors, but at the same time, how do we manage the symptoms related to the hormone excess and the different complications. Moreover, I think, as we discussed earlier, we need to manage these tumors in a multidisciplinary approach. And something very important is not like one size fits all, because the treatment recommendations, it will depend on different characteristics in terms of the tumor presentations. And hormone excess is one of the important aspects to recognize so that way we can implement these recommendations that will definitely help the quality of life of these patients. Brittany Harvey: Absolutely. And using these guidelines in concert with the systemic therapy guidelines is key. And then beyond this impact for clinicians that Dr. Del Rivero has just outlined, Dr. Perez, what does this new guideline mean for patients with gastroenteropancreatic neuroendocrine tumors? Dr. Kim Perez: Yeah, I think that's an important highlight of this guideline. It really gives patients a voice. I think it recognizes the fact that these symptoms can go unmanaged or mismanaged or just missed, and patients commonly will come in feeling very frustrated and feeling very ill. And I think it will provide them a means to open up a conversation with their providers and say, “Hey, this is what I'm experiencing. Let's talk about what's available. How does this apply to me?” And I think that can be very empowering. I think it's really hard nowadays with so many sources and resources online and patients are really left wondering what are the bullet points that they should be bringing to their clinician appointments? And I think that these guidelines provide them a good framework for those discussions. Brittany Harvey: Yes, bringing these discussion points for patients is very important to be able to have those resources. And we have some patient resources and information available on the website for this guideline and we can link that in the show notes for listeners. So then you've both touched on the importance of this guideline for improving quality of life and we continue to see advancements in this field. So Dr. Del Rivera, what are the outstanding questions regarding symptom management and tumor control for gastroenteropancreatic neuroendocrine tumors? Dr. Jaydira Del Rivero: I have to say whenever somebody asks me that question, the word that I will say is I feel hopeful, because more than 10 years ago we didn't have that many options for gastroenteropancreatic neuroendocrine tumors. And it has been in the last decade or so that there has been more developments in the management of these tumors as well as the understanding of the symptoms related to these tumors. But that said, yes, we do need more therapies for gastroenteropancreatic neuroendocrine tumors. Of the treatment options that we have, we all know in the field that even though we have disease control by using the different options for the systemic management of gastroenteropancreatic neuroendocrine tumors, we need options where we can achieve an objective response, especially for these tumor types. But there is a significant volume of disease and we see a lot of these patients with gastroenteropancreatic neuroendocrine tumors. And now where the field is going is to make some of these therapies more effective, to develop more therapies as well. For example, immunotherapies, a different type of immunotherapy understand the tumor immune microenvironment of these tumors in order to develop therapies as well. From the antibody drug conjugates, I think that's a new way to also address or treat these tumor types, understanding about the different markers found on these tumors that way they can be addressed in different ways. Now with the development of new therapies, I think that's something that can help us as well not only have disease control and as well as having an objective response, but having a better objective response can certainly also help with the symptoms related to hormone excess too. In terms of other therapies, I think some of the issues that we encounter are like the refractory carcinoid diarrhea and how do we manage this. We do have therapies that can help us control the diarrhea in the refractory settings, such as telotristat. Telotristat is one of the newer medications that can help us control the refractory diarrhea. But that said, despite this, that we still encounter situations where it's sometimes difficult to control. I think in those situations it will be good to understand more about the biology of these tumors as well and how we manage. If there is a different time or how do we implement these options. I think there is so much to learn. But that said, I feel we're in hopeful times. We're understanding more about these tumors so that way we can help us develop better therapies not only to have control of the tumor growth as well having control of the symptoms. And it's the same with the pancreas neuroendocrine tumors in the metastatic setting. Sometimes it may be difficult to control this hormone excess. But understanding these and having therapies that can achieve more of an objective response, I think that will definitely help us more and manage these patients. But one aspect I want to mention, and Dr. Perez also mentioned as well, the fact that we have these guidelines that help us understand about the different symptoms related to hormone excess and how to address it, I think is very important because having symptoms related to hormone excess can be detrimental to the quality of life on patients with neuroendocrine tumors that may necessarily be related to disease progression and having this information is so important. And I'm hopeful for the different therapies. There's different clinical trials ongoing for neuroendocrine tumors and especially in the field of PRRT. And a lot of more information will come with the different alpha-PRRT and combination therapy. So more information to come in the next couple of years. So this is, in my opinion, hopeful times for this field. Brittany Harvey: It's great to hear that you're hopeful for all the developments in this field and we'll look forward to the development and discovery of new therapies and further research and then, hopefully incorporate those updates into guidelines in the future. So I want to thank you both so much for your work to develop these guidelines and thank you for your time today. Dr. Del Rivero and Dr. Perez. Dr. Jaydira Del Rivero: Thank you so much for having us.

  • Systemic Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer Guideline Update
    Dr. Rohan Garje shares the updated recommendations for the ASCO guideline on systemic therapy for patients with metastatic castration-resistant prostate cancer. He discusses the systemic therapy options for patients based on prior therapy received in the castration-sensitive and non-metastatic castration-resistant settings. He emphasizes personalizing treatment choices for each individual, considering patient-specific symptoms and signs, treatment-related toxicities, potential drug interactions, cost, and access. He also reviews recommendations on response assessment. The conversation wraps up with a discussion of potential future updates to this guideline, as the guideline transitions into a “living guideline” on mCRPC. Read the full guideline update, “Systemic Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer: ASCO Guideline Update”. Transcript This guideline, clinical tools, and resources are available at www.asco.org/genitourinary-cancer-guidelines. Read the full text of the guideline and review authors’ disclosures of potential conflicts of interest in the Journal of Clinical Oncology.      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'm interviewing Dr. Rohan Garje from Miami Cancer Institute Baptist Health South Florida, lead author on, “Systemic Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer: ASCO Guideline Update.” Thank you for being here today, Dr. Garje. Dr. Rohan Garje: Absolutely. Thank you so much for having me, Brittany. Brittany Harvey: And then 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 Dr. Garje, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then, to start on the content of this guideline, first, could you provide us an overview of the purpose of this guideline update? Dr. Rohan Garje: Sure. So ASCO has guidelines for prostate cancer and the specific guideline which we have updated for metastatic castrate-resistant prostate cancer was originally published in 2014. It's almost a decade. It's been a long time due for an update. Over the last decade, we have seen a lot of advances in the treatment of prostate cancer, specifically with regards to genomic testing, newer imaging modalities, and also the treatment landscape. Now we have newer options based on genomic targets such as PARP inhibitors, we have radiopharmaceuticals, a newer variant of chemotherapy, and also some specific indications for immunotherapy which were not addressed previously. Because all these advances have been new, it was really important for us to make an update. In 2022, we did make a rapid update with lutetium-177, but these additional changes which we have seen made it an appropriate time frame for us to proceed with a newer guideline. Brittany Harvey: Absolutely. It's great to hear about all these advances in the field to provide new options. So I'd like to next review the key recommendations from this guideline. So let's start with the overarching principles of practice that the panel outlined. What are these key principles? Dr. Rohan Garje: As a group, all the panel members came up with some ground rules: What are necessary for all our patients who are being treated for metastatic CRPC? First, the founding aspect was a definition for what is metastatic CRPC. So we defined metastatic CRPC as castrate level of testosterone with evidence of either new or progressive metastatic disease on radiological assessments or patients who have two consecutive rising PSAs in the setting of existing metastatic disease. We also emphasized on the need for germline and somatic testing for patients with metastatic prostate cancer at an earliest available opportunity because it is critical to select appropriate treatment and also right treatment for patients at the right time. And we actually have a concurrent guideline which addresses what genes to be tested and the timing. The other principles are patients should continue to receive androgen deprivation therapy or undergo surgical castration to maintain castrate level of testosterone. Now the key aspect with these guidelines is personalizing treatment choices. As you can see the evolution of treatment options for prostate cancer, the drugs that were initially developed and approved for prostate cancer were primarily in castrate-resistant settings, but now most of these drugs are being utilized in castrate-sensitive. So, when these patients develop castration resistance, the challenges are there are no appropriate particular drug-specific guidelines they meet. So, it's very important for the clinicians to be aware of what treatments have been received so far prior to castration resistance so that they can tailor the treatment to patient specific situations. In addition, prior to choosing a therapy, it is important for the physicians to consider patient specific symptoms or signs, treatment-related toxicities, potential drug interactions, cost, and also access to the drugs. There may be multiple treatment options available for the patients, but for a patient specific scenario, there may be a drug that may be more promising than the others. So, it is important to tailor the drug choices based on patients' unique circumstances. The panel also recommends to early integrate palliative and supportive care teams for symptom management and also discuss goals of care with the patient as each patient may have unique needs and it's important for physicians to address those concerns upfront in the care. The panel also suggests patients to receive RANK ligand inhibitors such as denosumab or bisphosphonates such as zoledronic acid to maintain the bone strength to prevent skeletal-related events. Finally, I would like to also emphasize this point about the lack of randomized clinical trial data for optimal sequencing of therapies for patients with metastatic CRPC. As I previously alluded, we have taken into account all ongoing clinical trials, prior published data, and came up with a format of preferred drugs based on prior treatments and, I think, by following these several clinical principles which I just mentioned, we can optimally choose and utilize best treatments for patients with metastatic CRPC. Brittany Harvey: Absolutely. These principles that you just outlined are important for optimal patient care, and then I want to touch on one of those things. You talked importantly about the treatments received so far. So in the next set of recommendations, the role of systemic therapy was stratified by the prior therapy received in the castration-sensitive and non-metastatic castration-resistant setting. So starting with what does the panel recommend for patients who are previously treated with androgen deprivation therapy alone in these previous settings and whose disease has now progressed to metastatic castration-resistant prostate cancer? Dr. Rohan Garje: There are multiple treatment options based on prior treatment received. So for patients who received only ADT for their castration-sensitive disease, the panel strongly urges to get HRR testing to check for homologous recombinant repair related changes, specifically for BRCA1 and BRCA2 mutations, because we have three studies which have really shown significant clinical benefit for patients who have BRCA1 and BRCA2 mutations with drugs such as the combination of talazoparib and enzalutamide or olaparib with abiraterone or niraparib with abiraterone. Unless we test for those mutations, we'll not be able to give these agents upfront for the patients. In the HRR testing, if patients have HRR alterations but they are in genes which are non-BRCA, the guideline panel recommends to utilize talazoparib and enzalutamide based combination therapies. Now, if they don't have HRR alterations then there are multiple treatment choices available. It could either include androgen receptor pathway inhibitors such as abiraterone with prednisone. We could also consider docetaxel chemotherapy. The alternate choices for androgen receptor pathways include enzalutamide or the newer agents such as apalutamide and docetaxel. So, as you can see there are multiple options available, but the panel definitely emphasizes to test for HRR testing because this gives patients access to more precision therapies at this point. There may be various scenarios where a unique drug may be available for a specific patient situation. For example, patients who have very limited disease burden and may have one or two metastatic lesions, after a multidisciplinary discussion, targeted local therapies such as radiation or potentially surgery could also be offered. In select patients who have very indolent disease where they are castrate-resistant based on slow rising PSA, low-volume disease or asymptomatic disease can consider sipuleucel-T. And in patients who have bone-only metastatic disease, we could also consider radium-223, which is primarily now utilized for patients who have symptomatic bone disease. Brittany Harvey: Great. I appreciate you reviewing all those options and talking about how important it is to tailor treatment to the individual patient. So then the next category of patients, what is recommended for those who have been previously treated with ADT and an androgen receptor pathway inhibitor and whose disease has now progressed to metastatic castration-resistant prostate cancer? Dr. Rohan Garje: So for patients who received ADT along with an androgen receptor pathway inhibitor, which we consider would be a most common cohort because most patients now in castration-sensitive setting are receiving androgen receptor pathway inhibitor. It was different in the past where five or six years back ADT alone was the most common treatment, but fortunately, with enough awareness and education, treatment choices have improved. Patients are now receiving ADT and ARPI as the most common choice of drug. Once again, at this point the panel emphasizes to consider HRR testing in there is enough data for us to suggest that patients who have alterations in the HRR pathway definitely will benefit with the PARP inhibitor. You know the multiple options, but specifically we speak about olaparib. And then if they are HRR-negative, we prefer patients receive agents such as docetaxel or if they are intolerant to docetaxel, consider cabazitaxel chemotherapy, options such as radium-223, and if they have a specific scenario such as MSI-high or mismatch repair deficiency, pembrolizumab could also be considered. The panel also discussed about the role of a second ARPI agent. For example, if patients progressed on one androgen receptor pathway inhibitor, the second androgen receptor pathway inhibitor may not be effective and the panel suggests to utilize alternate options before considering androgen receptor pathway inhibitor. There may be specific scenarios where a second ARPI may be meaningful, specifically, if alternate choices are not feasible for the concern of side effects or toxicities or lack of access, then a potential ARPI could be considered after progression on ARPI, but the panel definitely encourages to utilize alternate options first. Brittany Harvey: Great. Thank you for outlining those options as well for those patients. So then the next category, what is recommended for patients who have been previously treated with ADT and docetaxel? Dr. Rohan Garje: For patients who received ADT and docetaxel and were never treated with androgen receptor pathway inhibitors, the panel again emphasizes on HRR testing. If they have BRCA1 and 2 mutations, the combination therapies of talazoparib with enzalutamide, olaparib with abiraterone, or niraparib with abiraterone are all good choices. If they don't have BRCA mutations but they have other HRR mutations, the panel suggests to potentially utilize talazoparib with enzalutamide. And if they do not have any HRR alterations, the options could include androgen receptor pathway inhibitors such as abiraterone or enzalutamide. I want to emphasize that these are preferred options, but not the only options. As you can see, there are multiple options available for a particular clinical situation - so the ability of the physicians to access particular combinations, the familiarity of those drugs or the patient's unique situation where they have other medications which can potentially interact with a choice of agents. So I think based on access, based on cost and patients' concurrent illness with potential drug interactions can make one particular combination of therapy better over the other options. Brittany Harvey: Absolutely. That's key to keep in mind that access, contraindications, and cost all play a role here. So then the next set of recommendations. What are the key recommendations for patients who have previously been treated with ADT, an androgen receptor pathway inhibitor, and docetaxel who now have mCRPC? Dr. Rohan Garje: Yes. In this group, the options remain, again, broad. We utilize PSMA imaging here specifically and if they are positive on PSMA imaging, lutetium-177 is a good option. If they do not have PSMA-positive disease on PSMA imaging but if they have HRR alterations, olaparib could be utilized. And if they are negative on PSA imaging, they don't have HRR alterations, then alternate options could include cabazitaxel, radium-223. And if they have MSI-high or deficiency in mismatch repair, pembrolizumab could be utilized in this setting. Brittany Harvey: Thank you for outlining those options as well. So then next the panel addressed treatment options for de novo or treatment emergent small cell neuroendocrine carcinoma of the prostate. What are those key recommendations? Dr. Rohan Garje: Yes. This is a very high unmet need group because there are limited clinical trials, especially prospective clinical trials addressing treatment options for this group. Most of our current guidelines are always an extrapolation from lung small cell cancer based guidelines, but the panel recommends to utilize cisplatin or carboplatin along with etoposide as a preferred choice for this group. Also, an alternate option of carboplatin along with cabazitaxel could be considered for this cohort. The panel also encourages participation in clinical trials. There are numerous trials ongoing now in smaller phase studies and I think it's important for patients to consider these trials as well, because this will give them access to newer agents with potential biological targets. In addition to these agents in specific scenarios or potentially case by case basis, because we don't have prospective data, so we have made it as a select case by case basis to consider adding immunotherapy along with platinum-based chemotherapy followed by maintenance immunotherapy, which is currently a standard of care in small cell lung cancer. But the data is so limited in prostate cancer, so the panel suggested that it has to be a case by case basis only. The alternate options also include lurbinectedin, topotecan, tarlatamab upon progression on platinum-based chemotherapy. Brittany Harvey: Yes. It's important to have these recommendations in these unique situations where there is really a lack of data. So then the final set of recommendations I'd like to cover, what does the panel recommend for how clinicians should assess for response while patients are on systemic therapy and what scans are recommended for this response assessment? Dr. Rohan Garje: Yes. Again, this is another strong emphasis of the panel for global assessment of the patients. Traditionally, patients and physicians per se are heavily reliant on PSA as an accurate marker for response. This is in fact true in earlier phases of prostate cancer either in castrate-sensitive setting or localized prostate cancer setting. But as patients evolve into castrate-resistant, we don't want to heavily rely on PSA alone as a marker of response. The panel suggests to incorporate clinical response, radiological response, and also include PSA as a component, but not just rely primarily on PSA. So the panel also suggests that patients should get a bone scan and a CT scan every three to six months while on treatment to assess for appropriate response or for progression. And now one key important aspect, we are all aware about the evolving role of PSMA-based imaging with several of these new agents that are currently available. We do acknowledge these scans definitely have an important role in the care for patients with metastatic prostate cancer. Currently, the utility is primarily to select patients for lutetium-based therapy and also in situations where the traditional scans such as technitium 99 bone scan or CT scan are equivocal, then a PSMA-based imaging can be helpful. Now we are also aware that there are newer studies coming up, prospective data coming up for the role of PSMA-based imaging for response assessment. We are hoping to update the guidelines if we get access to newer data, but currently we have not recommended the utility of PSMA-based imaging for response assessments. Brittany Harvey: Understood. And I appreciate you describing where there is data here and where there's a lack of data to currently recommend. And we'll look forward to future updates of this guideline. Coming back to – at the start you mentioned how much has changed since the last guideline update. So Dr. Garje, in your view, what is the importance of this update and how will it impact both clinicians and patients with metastatic castration-resistant prostate cancer? Dr. Rohan Garje: The updated guidelines are designed to have a significant impact on clinical practice and also patient outcomes by providing clinicians with a comprehensive evidence-based framework for managing patients with metastatic CRPC. And also, by using these guidelines can make informed decisions, can select therapies tailored to patients’ unique genomic status, clinical situation, where they are in the course of the cancer based on what they received previously. Also utilizing these guidelines, we can potentially improve patient outcomes, improve survival, and importantly have efficient use of healthcare resources. Brittany Harvey: Absolutely. We're always looking for ways to improve patient outcomes and survival. I want to wrap us up by talking a little bit about the outstanding questions in this field. So earlier you had mentioned about prospective data to come about PSMA PET scans, but what other outstanding questions are there for patients with metastatic castration-resistant prostate cancer? And what evidence is the panel looking forward to for future updates? Dr. Rohan Garje: We do have now rapidly evolving data specifically about the utility of the radiopharmaceutical lutetium-177 prior to chemotherapy. We are hoping that with newer data we can make some changes to the guideline based on that. We are also looking at newer drugs that are coming up in the pipeline, for example, androgen receptor degraders. We are looking at data that might potentially help based on bispecific T-cell engagers and newer radiopharmaceuticals. So I think in the next few years, we will definitely update all the guidelines again. But this time we are trying to do it more proactively. We are following a newer model. We are calling it as ‘living guidelines’ where we are actually utilizing week by week updates where we look at the literature and see if there is any potential practice impacting change or publication that comes up. And we are trying to incorporate those changes as soon as they are available. That way patients and practicing physicians can get the latest information available through the guidelines as well. Brittany Harvey: That's great to hear. Yes, we'll await this data that you mentioned to continuously update this guideline and continue to improve patient outcomes for the future. So Dr. Garje, I want to thank you so much for your time to update this guideline. It was certainly a large amount of recommendations, and thank you for your time today, too. Dr. Rohan Garje: Thank you so much for having me here. And it's always nice talking to you. Brittany Harvey: And finally, thank you to our listeners for tuning in to the ASCO Guidelines podcast.
