Recent advances in metastatic urothelial carcinoma have meant that optimistic outcomes are “not as much of a fairytale,” says Robert Dreicer, MD, deputy director of the UVA Cancer Center and professor of medicine and urology at the University of Virginia School of Medicine in Charlottesville. From the recent approval of enfortumab vedotin plus pembrolizumab to other key findings recently presented at the American Society of Clinical Oncology Genitourinary Cancers Symposium, Dr. Dreicer discusses “paradigm-shifting” advances with Robert A. Figlin, MD, the Steven Spielberg Family Chair in Hematology-Oncology at Cedars-Sinai Cancer Center in Los Angeles. Dr. Dreicer explains the “deal-breaker” that renders one treatment strategy “a relative no-brainer” for certain patients, as well as what upcoming data are likely to change practice even more.

Listen to a blog summary of a recent research paper published by Oncotarget, entitled, "Combined epigenetic and immunotherapy for blastic and classical mantle cell lymphoma." __________________________________________ Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma (NHL) that is aggressive, difficult to treat and typically affects older adults. Recurrence and mortality rates among patients with MCL have remained high, despite recent therapeutic advances. Blastic mantle cell lymphoma (bMCL) is a rare subtype of MCL associated with a worse disease trajectory. “Despite recent advances, MCL is incurable except with allogeneic stem cell transplant. Blastic mantle cell lymphoma (bMCL) is a rarer subtype of cMCL associated with an aggressive clinical course and poor treatment response, frequent relapse and poor outcomes.” In previous studies, researchers reported that a combination of epigenetic and immunotherapy treatments may have synergistic activity and offer better outcomes in patients with MCL. In the current study, Francis R. LeBlanc, Zainul S. Hasanali, August Stuart, Sara Shimko, Kamal Sharma, Violetta V. Leshchenko, Samir Parekh, Haiqing Fu, Ya Zhang, Melvenia M.

Dr. Velcheti is the director of thoracic medical oncology at New York University Langone's Perlmutter Cancer Center. View disclosures for Dr. Gentzler, Dr. Le, Dr. Stiles, and Dr. Velcheti on Cancer.Net. Dr. Gentzler: Thank you, everyone, for joining us. We've got a great group here today, and we're really going to focus on talking about molecular testing in lung cancer. This is a very hot topic. My name is Ryan Gentzler from the University of Virginia. I'm a thoracic medical oncologist. We have Drs. Le, Stiles, and Velcheti with us today. I'd like them to go ahead and introduce themselves, starting with Dr. Le. Dr. Le: My name is Xiuning Le. I'm an assistant professor. I'm at the MD Anderson Cancer Center here in Houston, Texas. I'm also a medical oncologist. Thank you, Ryan, for inviting us today. Dr. Stiles: Hey, everybody. I'm Brendan Stiles. I'm a thoracic surgeon. I'm chief of thoracic surgery at Albert Einstein College of Medicine in Montefiore Health System here in the Bronx in New York. Dr. Gentzler: All right, thanks for joining us. And Dr. Velcheti. Dr. Velcheti: Thank you, Ryan. I'm Vamsidhar Velcheti. I'm the director of the thoracic oncology program at NYU. Dr. Gentzler: All right, great. We hear a lot of terms thrown around about molecular testing, genomic testing, biomarkers, oncogenic drivers, and I thought it would be good to just define what exactly is molecular testing, so all of our listeners are aware of what we're talking about. Dr. Le, do you want to take this question? Dr. Le: Yeah. So we have many terms, as you described. In my eyes, there are 2 sets of testing, and then some of them also classify into actionable versus not actionable. So for clinical use, we usually ask the tumor to be tested for both the mutations as well as the immune marker. Usually, the panel of mutational testing is more than a field. Usually, it's depending on the platform we're using, oftentimes in the hundreds of things. And then the immune markers, usually, we refer to PD-L1 and the tumor mutational burden. Those are the 2 commonly used markers now in the clinic. Some of those markers, especially the hundreds in gene testing, not all of them can lead to a clinical decision because we're still in the phase of understanding the interactions of different genes. However, there is a subgroup of those mutations. Nowadays, we have targeted therapy for, we call those actionable mutations. So in the clinic, we push for testing for a panel of mutations as well as immune markers, hoping to look at the tumor comprehensively so that we can recommend a good treatment regimen precise to that particular tumor, precise to that particular patient. Dr. Gentzler: Yeah. Wonderful. This has also been termed precision medicine, where we really match a therapy to a specific genomic abnormality identified on these tests and maybe, Dr. Velcheti, if you could maybe elaborate on some of the different ways that these tests are performed and how we're using these in clinic today? Dr. Velcheti: Yeah, definitely. I think our understanding of the biology of lung cancer has evolved quite dramatically over the past several years and obviously it's led to a lot of advancements in terms of treatment opportunities for patients. Broadly, the way I look at biomarkers in lung cancer or, for that matter, any cancer, it's like you have biomarkers that actually kind of give us very deep insights into the biology of the cancer and giving us insights into how aggressive somebody's cancer is. Those are called prognostic biomarkers, kind of predicting outcome. And there are predictive biomarkers where there are certain biomarkers. If you do have some of these biomarkers in the tumor, then you could potentially use certain treatments that might work better for patients who have those biomarkers. So now we have a lot of different approaches in terms of how we kind of test for these biomarkers. Especially in lung cancer, now we have a lot of new therapeutics for certain genomically categorized types of lung cancer. And the challenge now is that we have so many different mutations we absolutely need that information to decide on treatment. So how do we test that? Until a few years ago, we've been doing a single gene testing. The problem with those approaches is that we have so many different genes we need to test and we kind of do sequential gene testing, a single gene testing, we won't get all the information we need to make the right decision for our patients. So the standard approach in most oncology practices, especially larger cancer centers and academic medical centers, is do comprehensive genomic profiling, and that's being widely accepted as a standard approach right now. Dr. Gentzler: Wonderful. And this has really been something that has fallen on the laps of thoracic medical oncologists as we've treated patients with advanced stage or stage 4 disease. And this is starting to become more and more important and relevant for surgeons. And Dr. Stiles, I just wanted to bring you into the conversation and see if this is something that, prior to some of the more recent data, which we'll discuss in a minute, is this something that as a surgeon, you've kept up with and think it's important in a surgical practice? Dr. Stiles: Yeah, definitely, Ryan. And I think now is probably the most exciting time for that, right? We used to just be sort of in the prognostic side, like Vamsi said, but now we really are in the predictive side in the early-stage disease. And I think that's why everybody is so excited. But that's why there's now this pressure about the timing of biomarker testing. What do you get? Do you get a whole panel? As we'll talk about some of the trials that have made their way into earlier stage disease, but it becomes inherent upon surgeons to really think about this and understand this, from the first time that they meet the patient I think, as we increasingly get better therapies in earlier stage disease. Dr. Gentzler: So as this has moved into earlier stage disease, a lot of this has been driven by some new data from clinical trials, and Dr. Velcheti, I thought maybe you could comment on the IMpower010 trial and its relevance and why molecular testing is important in the context of that trial. Dr. Velcheti: Yes, absolutely. I think the IMpower010 Trial is certainly a new shift in our approach to treating stage I, II curable non-small cell lung cancers. So we haven't had an approval in the adjuvant setting in a while. I mean, of course, we had approval with the osimertinib result of the ADAURA trial, but that's only for EGFR patients. Now we have approval for using immunotherapy in the postoperative adjuvant setting for patients with any level of PD-L1 expression. So this is a large randomized study looking at the role of adjuvant atezolizumab, which is a PD-L1 inhibitor in patients who have PD-L1 expression greater than 1%. Patients were randomized getting platinum doublet alone, which is a standard-of-care adjuvant assistant therapy for patients at stage I, II lung cancer. It is atezolizumab at a dose of 1,200 milligrams given every 3 weeks. Patients who received atezolizumab had significantly improved outcomes in disease-free survival. And the benefit was actually really striking for patients who had high PD-L1, patients with PD-L1 testing TPS score of greater than 50%. They had a really remarkable increase in terms of disease-free survival for those patients. So this is certainly very encouraging. And of course, we know it's now approved. We are still awaiting some overall survival results to mature. But given the extent of the benefits we're seeing with the disease-free survival, I think it's a very promising approach. Dr. Gentzler: Yeah, so obviously, immune therapy has had a tremendous benefit in the adjuvant setting from this trial and still some longer-term follow-up that's needed. But I think the important point here is that molecular testing may identify certain mutations that may make patients less likely to benefit or respond, or perhaps there's more appropriate treatments than immunotherapy within this group. And that brings us to the next trial that I think really shifted this discussion stage with the ADAURA trial. Maybe Dr. Le, if you could summarize this trial and give us your thoughts on why molecular testing is so important in the era of ADAURA. Dr. Le: Yeah. So ADAURA trial is also an adjuvant trial, meaning that the patient received additional treatment after the completion of surgery. So ADAURA trial looked at patients who have EGFR mutations. So it's a different biomarker. It's a gene biomarker, not the immune biomarker. So this is a large international trial, enrolled almost 700 patients and then randomized the patients after surgery, after standard chemo, the patient can go on to either receive 3 years of osimertinib, which is the standard-of-care therapy for EGFR mutant patients for metastatic setting, or the control group if the patient just received standard of care, which is to continue the monitoring. The trial actually showed that for people who had osimertinib before that prolonged time of 3 years, the risk of the disease coming back is almost 5 times lower than the patient who did not receive therapy. So based on that really striking benefit of after surgery, after chemotherapy, continue osimertinib in EGFR patients, FDA approved after the surgical resection and all the standard care patient can go on for osimertinib for a prolonged time, which we think currently the data is saying the disease is more likely not to come back. And hopefully, in the future, that result will translate into overall survival benefit. Dr. Gentzler: Okay, wonderful. And I think both of these trials, both the ADAURA and the IMpower010, are adjuvant trials. So these are trials that allow us adequate time to do molecular testing on a large surgical specimen, formulate our plans, and implement those plans up to a month or longer after surgery. Obviously, there's some new data that we've seen in a press release from the CheckMate 816 trial. This is a neoadjuvant trial of chemotherapy plus nivolumab. We've seen previous data from this trial showing some results, but this moves the conversation into the neoadjuvant space, and Dr. Stiles, I wonder if you could give us a summary of your thoughts on the CheckMate 816 and the relevance for molecular testing in that context of neoadjuvant therapy. Dr. Stiles: Yeah. Thanks, Ryan. I think, first of all, those are incredibly important adjuvant trials. I saw 2 patients each this week on adjuvant osimertinib and adjuvant atezo [atezolizumab], so it's real-life practice. Every day, it's going to benefit patients. But I think that's easy, like you said, these are big specimens that are taken out. You've got time to decide while the patient gets better. Now, we have to shift all this even earlier because CheckMate 816 really has some pretty impressive results. We, unfortunately, don't have the paper yet. I'm told it's going to be coming out soon, but the primary endpoint pathologic complete response 24% versus 2.2%. That's with chemo-nivo versus chemo alone. Obviously, people are questioning, does pathologic complete response correlate with outcomes? Certainly, we got a signal on a press release that the event-free survival is going to be the hazard ratio is 0.63, so it sounds like it does, and I think we'll see more data on that in the next couple of months. A difference in median event-free survival of 32 months versus 21 months in the report. So everybody is excited to see this. And I think it has some advantages over the adjuvant strategy. First of all, more patients are able to tolerate it. It's just 3 cycles, and so it's not given indeterminately for a year. And it worked across different subgroups. And we can talk about some of the nuances, but as where atezo [atezolizumab] was only looking good in the PD-L1-high. This sort of worked across different groups. The caveat to that is we don't really know what happens with these EGFR patients who are eligible and sort of, how do we then move that test? And all of a sudden, we've got to make a decision on neoadjuvant therapy. Now we need to know. It helps to know the PD-L1 maybe preoperatively, with the high PD-L1, maybe you could wait until adjuvant therapy, with the low to sort of medium PD-L1, maybe you want to give them their shot in the neoadjuvant space. But if they have an EGFR mutation, it's probably not the right thing. We don't really know the data on that and CheckMate 816 yet, but certainly, I'd be sort of hesitant to give them neoadjuvant chemoimmunotherapy. So then you have to teach surgeons all this too, and teach them to think about this and teach them to hold their horses on taking patients to the operating room while they wait for molecular testing. But that probably means we need to speed up the process somewhat either with sort of more rapid turnaround test, with consideration of liquid tests in some instances. It's just an incredibly fast-changing place that here we are speaking about a trial that hasn't even been published yet, so that tells you how fast things are happening. Dr. Gentzler: One last question. How can the results of these tests guide therapy after surgery? Do we incorporate a full NGS [next-generation sequencing] panel at the time of surgery? And we don't have data on adjuvant therapy for ALK or ROS1, or RET. Do we factor that into how we think about adjuvant chemotherapy, adjuvant immunotherapy, do we employ targeted therapies for some of these mutations? Any thoughts on that? Dr. Le: Ryan, I think you bring an important point in that EGFR is 1 of the 8 actionable mutations we have nowadays based on FDA and NCCN. The tumor biology between EGFR and ALK-fusion oncogenesis and potential response and benefits probably share some similarities. So we look forward to seeing trials reporting out the adjuvant setting with ALK inhibitors with ROS1. And the smaller target might require a multi-institutional or co-op group effort to really achieve the sample size for us to see. But as of now, we don't have the approval. We try to enroll patients to the oncogene trials, but I think currently we're practicing based on EGFR and PD-L1. Dr. Stiles: Yes, and I agree. I'm excited to see what comes out of some of those trials. They're slow to grow, but we'll eventually get some readouts. I think an interesting question sometimes is PD-L1. And we had an example recently where in the pre-op biopsy, the patient had a low PD-L1, and so not particularly enthusiastic. And the question sometimes arises, do you test that whole tumor to consider them as kind of an adjuvant to atezo [atezolizumab]and then the fully resected tumor, the PD-L1 was greater than 50%. And so I would sort of sound a caution that the small biopsy sample, they're incredibly helpful for many things, incredibly helpful for moleculars. It may not always be totally representative of the PD-L1 staining. Dr. Gentzler: And I think that's a good point. Even for molecular testing, sometimes if you have smaller biopsies, you may get a result that's negative, but it could be low levels of DNA and not sufficient to complete the full panel with high quality. So you really have to pay attention to the report and make sure that there's some confidence in the amount of DNA in some of these results. Well, I think that's all the time we have here, so I appreciate everyone's participation, and hopefully we're able to learn a little bit about genomic testing today.

The percent positivity has increased to 7.7 percent. In the Blue Ridge Health District, there are 37 new cases today and the percent positivity is at 4.6 percent. There have been 244,944 cases of COVID since mid-January, and of that amount, 98.34 percent of cases were in people not fully vaccinated. Of 2,838 deaths, that figure is 98.17 percent. (The above paragraph was corrected to fix a typographical error)In Albemarle County, 73.2 percent of adults are fully vaccinated, or 63.6 percent of the total population. In Charlottesville, 61.8 percent of adults are fully vaccinated, or 54.7 percent of population. The numbers in outlying counties are lower. For instance, in Louisa the figures are 54.4 percent of adults and 45.5 percent of the total population. In Fluvanna those numbers are 64 percent and 54.5 percent. In Greene, those numbers are 63.3 percent and 56.8 percent, and in Nelson 65.3 percent of adults are vaccinated and 55.6 percent of the total is fully vaccinated.The University of Virginia Health System has announced they will make vaccines available in their outpatient pharmacies by appointment, weekdays between 11 a.m. and six p.m. Justin Vesser has helped lead the health system’s vaccination efforts. “So we’re at this time when we sincerely hope everyone makes the decision to become vaccinated and there’s a lot changing on the vaccine front and a lot changing on the COVID front with the Delta variant and the current surge that we’re in,” Vesser said. These are in addition to the vaccinations at the COVID clinic.“We have community pharmacies that are UVA pharmacies in Zion Crossroads, we have them in Fishersville, we have them at UVA Cancer Center at Pantops, one in the UVA Bookstore, and one at student health clinic on the UVA campus,” Vesser said. Masks are now required indoors at all public schools in Virginia, per a public health emergency order issued yesterday by Governor Ralph Northam. Even though the state of emergency has elapsed, the public health emergency is still in place. One whereas clause in the order point out that children under the age of 12 are not eligible for a vaccine yet. (read the resolution)Among the others: Only 40.3% of 12-15 year-olds and 51.7 % of 16-17 year olds in Virginia are fully vaccinated as of August 10, 2021Universal and correct mask use is an important COVID-19 prevention strategy in schools as part of a multicomponent approach and has been shown to be associated with lower incidence of COVID-19 in schoolsThe Centers for Disease Control and Prevention (CDC) advises universal indoor masking for all teachers, staff, students, and visitors in K-12 schools, regardless of vaccination statusExceptions are made for anyone eating or drinking, exercising, for participation in religious rituals, and for those with health conditions that prevent wearing a mask. The U.S. Census Bureau has released population and demographic data from the tally in 2020. According to the count, Charlottesville officially has 46,553 people, a 7.08 percent increase from 2010. Albemarle’s population is 112,395, a 13.56 percent increase since 2010. Louisa County’s population increased by 13.4 percent to 37,596, Greene increased 11.68 percent to 20,552, and Fluvanna grew 6.06 percent to 27,249. Nelson County’s population shrank by 1.63 percent to 14,775. Overall, the Thomas Jefferson Planning District Commission increased by 10.4 percent to 259,120.Virginia as a whole has an official population of 8,631,393, a 7.9 percent increase since 2010. There are 218.6 people per square mile. Charlottesville has a density of 4,544 people per square mile, and that figure is 156 people per square mile in Albemarle County. (population and housing data viewer)A major purpose of the Census is to allocate seats in the U.S. House of Representatives. Virginia will continue to have 11 members. Albemarle County is looking for a consultant to help update its zoning order. On Tuesday, Planning Director Charles Rapp hosted a briefing for representatives of firms interested in doing the work. “The zoning ordinance exceeds probably 30, 40 years of life and its in need of an update,” Rapp said. The chosen firm will enter into a multi-year contract to do the work in phases. “We have an initial phase outlined in this [request for proposals] that focuses on zoning district land use clarifications and setbacks as kind of the first two sections,” Rapp said. Subsequent phases will be undertaken as Albemarle begins to update its Comprehensive Plan. “As we finish sections of the Comprehensive Plan, we will identify sections of the zoning ordinance that correspond with that topic,” Rapp said. “So an easy one to talk about is natural resource planning. So a zoning ordinance that might relate to natural resources would be landscaping, lighting, stream buffers, all of that kind of stuff.”Back to that first phase. Rapp said this would be an update to transition toward a more modern zoning code that is easier to use and better organized. “We would like to get a consultant on board by October,” Rapp said. A second request for proposals will be released soon for a consultant to work on the Comprehensive Plan. After this brief break, catching up with the Charlottesville Planning Commission.

They’ll have two work sessions coming up, and the agenda for this one was relatively light. As always, the meeting began with updates from Commissioners, including the nonvoting representative from the University of Virginia, Bill Palmer. “I don’t have a whole lot to report other than just the reminder that fall semester starts on August 24 and we’ll be in pretty full swing around Grounds with first years coming back for orientation and all that,” Palmer said. Commissioner Rory Stolzenberg noted the finalization earlier this month of a key global update of how the entire world’s climate is changing. “The Intergovernmental Panel on Climate Change has released the first part of its sixth assessment report and most of the stuff in there is bad news and some of it is tentatively good news if we act on it and I would encourage all of you to read it,” Stolzenberg said. Stolzenberg said the report shows the global temperature will likely continue to rise above the 1.5 degrees Celsius of warming considered to be an important threshold. Efforts to reduce greenhouse gas emissions are intended to keep that number lower.“And we’re most likely looking at three degrees or more unless we can get very significant reduction in greenhouse gas emissions,” Stolzenberg said. Stolzenberg said the good news is that if the world can get to net zero, temperatures could eventually begin to go down. (view the various reports on the IPCC website)James Groves, an associate professor in the Department of Engineering and Society at the University of Virginia, spoke about the report during matters from the public. He said it is the first update from the IPCC since 2013.“Without surprise, the report states that our lifestyles are dangerously eroding the natural world around us, setting the stage for increasingly difficult living conditions for everyone and everything,” Groves said. Groves said he hopes the Comprehensive Plan needs to have specific recommendations related to climate change such as recommending specific financing mechanisms to replace heating and cooling systems. “Investments in sustainability solutions like [Commercial Property Assessed Clean Energy] financing, a green bank, and micromobility could put critical dollars in the pockets of our most needy neighbors, year after year, while stabilizing the climate for all of us,” Groves said.Speaking of the Charlottesville Comprehensive Plan, the firm Rhodeside & Harwell updated the city Planning Commission on the next steps for the Cville Plans Together Initiative. In February 2019, a previous Council opted to spend nearly a million dollars on a firm to complete the Comprehensive Plan, rewrite the zoning code, and adopt an affordable housing plan. That last step was completed in March. Jennifer Koch is with Rhodeside and Harwell.“What we’ve heard from you all is that you’d like to see us have a Comprehensive Plan to Council this year,” Koch said.The consultant team continues to review the feedback submitted this spring in six-week public input window on the Future Land Use Map and some of the draft chapters of the Comprehensive Plan. There’s an upcoming work session on August 31. “We’ll come to you with what we’re proposing as some adjustments to the Future Land Use Map and the Land Use, Urban Form, and Historical, Cultural Preservation chapter to respond to what we heard,” Koch said. Planning Commission Chair Hosea Mitchell said he thinks it is crucial to get a Plan for the current City Council to vote on before the end of the year.“Slippage is not an option,” Mitchell said. “We do not want to have to educate a new Council. If it slips, we could be looking at another couple of years.”More to come in the near future. This is a public episode. Get access to private episodes at communityengagement.substack.com/subscribe

Cancer research discussed in this podcast is ongoing, so the data described here may change as research progresses. In this podcast, Cancer.Net Associate Editor Dr. Michael Williams talks about new research and advances in the field of lymphoma, including 3 recent U.S. FDA drug approvals. The research discussed was presented at the 2020 American Society of Hematology Annual Meeting, held virtually December fifth through eighth. Dr. Williams is the Chief of the Hematology/Oncology Division and Director of the Hematologic Malignancies Program at the UVA Cancer Center. He is also the Byrd S. Leavell Professor of Medicine and Professor of Pathology at the University of Virginia School of Medicine. View Dr. Williams’ disclosures at Cancer.Net. Dr. Williams: Hello. This is Dr. Michael Williams. I'm professor of medicine at the University of Virginia Health System in Charlottesville, Virginia, and I'm pleased to welcome you to this podcast for Cancer.Net. I'm reporting on some of the exciting updates that were just presented at the American Society of Hematology Annual Meeting. Typically, this is a meeting of 30 or 35 thousand clinicians and investigators from around the world. This year, as with so many meetings, we met virtually, but I would say very successfully done. Lots of exciting new data, and I'll try to give you a glimpse of what some of the progress has been. Before I start, I'll mention a few disclosures. So I have research grants that are awarded to the University of Virginia for clinical research from Celgene, Janssen, Pharmacyclics, and TG Therapeutics. And I have served as a consultant for Celgene, Janssen, and Pharmacyclics, as well as Kyte Pharmaceuticals, which is a division of Gilead. So the advances this year weren't just at the meeting. There were 3 new drug approvals in the past 6 months for lymphoma. Tazemetostat, which is an EZH2 inhibitor, was approved for relapsed/refractory follicular lymphoma patients who have a mutation in a gene called EZH2. So they showed good tolerance of this treatment with high response rates in these patients with the mutation. So it provides another important treatment option for people with relapsed follicular. A new approval for relapsed diffuse large B-cell lymphoma was a novel monoclonal antibody called tafasitamab given in combination with lenalidomide that also showed good responses and generally very good tolerance in people with relapsed aggressive lymphoma. So a welcome addition again to our treatment options. And then finally, a chimeric antigen receptor T-cell therapy or CAR-T was approved for relapsed/refractory mantle cell lymphoma. And I will say a bit more about that agent as we get into the discussion about CAR-T therapy for mantle cell. The first abstract presentation that I want to mention is in chronic lymphocytic leukemia or small lymphocytic lymphoma which, of course, is really 1 disease. It's just a spectrum of whether you have more of a leukemic phase or a lymph node enlargement component to your disease. Treatment in CLL has really shifted in recent years away from cytotoxic chemotherapy and is now well established that most patients needing treatment, whether for newly diagnosed disease or for patients who have been previously treated with other regimens, that targeted therapies such as Bruton tyrosine kinase inhibitors or a BCL-2 inhibitor venetoclax can get very high response rates. There's been interest among many groups in testing combinations of targeted drugs, and we heard an update of a report called the CAPTIVATE study that combines ibrutinib plus venetoclax. Both of these are oral agents. As a randomized study for patients with CLL who need treatment and have not been previously treated for their CLL. And what this study did was provided a combination of the 2 drugs as first-line therapy, and they showed that after a period of about 12 cycles of combined treatment, that you had very, very high remission rates. They used a very sensitive method, a molecular method, to detect minimal residual disease. And if patients were in a deep molecular remission, so undetectable MRD at the end of treatment, they were randomized to continuing with either no therapy or with just ibrutinib alone. And it was found that after a year, there was really no difference. So it shows that with combination therapy, you can get a deep enough remission to have a durable and ongoing response for those patients. They also randomized those who still had detectable residual disease to either ibrutinib alone or a combination of ibrutinib plus venetoclax, and they showed that their outcome at the end of treatment was likewise similar. So it shows a very good non-cytotoxic-chemotherapy-based approach to treatment of chronic lymphocytic leukemia, small lymphocytic lymphoma. So the second item I wanted to bring your attention was for another form of indolent or low-grade non-Hodgkin lymphoma called Waldenstrom macroglobulinemia which is also identified as lymphoplasmacytoid lymphoma. And in this study, they used a combination of ibrutinib plus rituximab, an anti-CD20 monoclonal antibody, versus placebo with rituximab alone. So this study is reporting now long-term follow-up with more than 5 years since the onset of treatment initiation in 150 patients. So rituximab by itself was a standard of care for patients with Waldenstrom at the time the study was designed. We now know that ibrutinib can give very good responses, especially when given in combination with rituximab. And indeed, they showed that now with 5 years of follow-up, that the response in terms of the serum IgM level, which is a marker for activity of this disease, improvement in anemia as well as objective response rates were much improved with the combination of ibrutinib plus rituximab versus rituximab alone. They also showed that there was a delay in the time that a patient needed another line of therapy for progressive disease when they had that combination. So important long-term follow-up there confirming the safety and activity of ibrutinib and rituximab for that disease. And then finally, I'll give an update on 1 of many reports at this meeting on CAR-T cell therapy. So just to remind those of you who may not be so familiar with this, it's a technique of cellular therapy, wherein a patient who's got disease progression with follicular lymphoma or mantle cell lymphoma or diffuse large B cell lymphoma, the patient undergoes a procedure where T-cells are removed from their blood, and then in the laboratory, they are reprogrammed to attack the patient's lymphoma cells. So the reprogramming is done, the CAR-T cells, the chimeric T-cells are expanded, and then shipped back to the treating center where the cells are infused intravenously to the patient. There is already an approval of CAR-T cell therapy for diffuse large B-cell lymphoma as I mentioned. It is now approved CAR-T called axicabtagene ciloleucel or axi-cel is approved for mantle cell lymphoma, and what we heard at this in Boston. She gave an update on treatment of relapsed refractory follicular lymphoma and marginal zone lymphoma with the axi-cel CAR-T. So what Dr. Jacobson and her colleagues reported was for patients with relapsed and refractory follicular lymphoma, the overall response rate was 95%, with 80% of these patients being in a complete remission with ongoing follow-up. In those with marginal zone lymphoma, the numbers of patients treated were smaller, but they also showed high-response rates, 85% with 60% achieving a complete remission. And at a year of follow-up, most patients were remaining without evidence of disease progression. So a very promising advance in follicular lymphoma. It also raises the possibility that we may be able to use CAR-T cell therapy instead of traditional autologous stem cell transplantation for relapsing patients. But this is something that will have to be tested in formal clinical trials before becoming established as a new standard of care. So by the end of the meeting, it was clear that progress continues at a very rapid pace across the fields of human logic malignancies, lymphomas, leukemias, multiple myeloma, and others. So it reminds us that it's important if you're dealing with 1 of these disorders that you make sure you've done your due diligence in getting another opinion if that's warranted, at seeking out clinical trials which help bring some of these most promising therapies to the clinic and help us advance the progress in treatment as rapidly as possible. So I'd like to thank you for your attention today and wish you all the very best in the year ahead. ASCO: Thank you, Dr. Williams.

Cancer research discussed in this podcast is ongoing, so the data described here may change as research progresses. Every year, the ASCO Annual Meeting brings together attendees from around the globe to learn about the latest research in the treatment and care of people with cancer. This year, attendees from 138 countries worldwide gathered virtually for the ASCO20 Virtual Scientific Program, held Friday, May 29 through Sunday, May 31. In the annual Research Round Up podcast series, Cancer.Net Associate Editors answer the question, “What was the most exciting or practice-changing research in your field presented at the ASCO20 Virtual Scientific Program?” In this final episode of 2020, editors discuss new research in the fields of central nervous system tumors and lymphoma. First, Dr. Glenn Lesser will discuss new research on a form of non-Hodgkin lymphoma that begins in the central nervous system, and research into a possible treatment for breast cancer that has spread to the brain. Dr. Lesser is the Louise McMichael Miracle Professor and Associate Chief in the section on Hematology and Oncology in the Department of Internal Medicine at Wake Forest University, with joint appointments in the Departments of Anesthesiology, Neurosurgery, and Public Health Sciences. He is also the Cancer.Net Associate Editor for Central Nervous System Tumors. View Dr. Lesser’s disclosures at Cancer.Net. Dr. Lesser: Hello. My name is Glenn Lesser, and I'm a professor of medical oncology and director of medical neuro-oncology at the Wake Forest Baptist Comprehensive Cancer Center in Winston-Salem, North Carolina. I'm also the editor of the brain tumor section for ASCO's Cancer.Net. And today, I would like to briefly discuss what I think are 2 of the most clinically relevant research studies on brain tumors that were presented at this year's ASCO's Virtual Scientific Program. I should say right up front I have no disclosures or relationships that are relevant to the particular studies I'll be discussing today. Unlike the progress we've seen in the treatment of many cancers over the past few years, patients with brain tumors and the physicians who care for them have not seen the same rapid advance in effective treatment strategies. Cancer that begins in the brain, so-called primary brain tumors, and the more common situation of cancer that spreads to the brain after originating elsewhere in the body, so-called metastatic or secondary brain tumors, still have relatively few effective treatment options available. However, I believe that the 2 abstracts we'll discuss today may impact the way that we treat certain primary and metastatic brain tumors in the future. The first study I'd like to talk about was presented by Dr. Omuro on behalf of a group of international colleagues that described a randomized study of standard chemotherapy with or without low dose whole brain radiation in patients with a brain tumor known as a primary central nervous system lymphoma, which I may also talk about as a PCNSL for abbreviation. Non-Hodgkin's lymphoma is a relatively common cancer that involves the blood and lymph nodes throughout the body. Primary central nervous system lymphoma is the term used when patients develop a non-Hodgkin's lymphoma that's confined to the central nervous system which is really made up of the brain, the spinal cord, the spinal nerves, and the spinal fluid. This turns out to be a pretty rare diagnosis with only about 1,500 new cases of this cancer occurring in this country each year. This type of lymphoma is important, though, because it's very treatable in most patients, and a significant percentage of our patients can be cured with appropriate therapy. Because the disease is so rare, we really don't have the results of large clinical trials to help us determine the best treatment approach for patients with primary central nervous system lymphoma. And as a result, there are a variety of controversies over how to initially treat patients who develop this lymphoma, so-called induction therapy, as well as what type of treatment to give once the disease has been made to go away, or so-called consolidation therapy. In the past, radiation therapy to the whole brain was used to treat patients with PCNSL. And most of these patients who were treated with radiation-containing regimens had their tumors respond, although the cancer frequently returned within a year or 2. This approach has really fallen out of favor over the last few decades because of the very high incidence of neurotoxicity or brain damage from the radiation that was seen in surviving patients. Unfortunately, a significant number of those patients who were treated with high doses of whole-brain radiation therapy developed a progressive irreversible dementia over the years following the radiation treatments, and a particularly high incidence of this toxicity was seen in patients who are over the age of 50. With current multi-agent chemotherapy regimens, a high percentage of treated patients are having their lymphomas go away. Unfortunately, a significant number of patients still have their disease come back within months or years of this treatment. And so strategies to consolidate or lock in that initial good result with treatment are being evaluated. These strategies may involve high doses of different types of chemotherapies, consideration of bone marrow or stem cell transplant, and even long-term maintenance treatment with oral chemotherapies. More recently, low doses of whole-brain radiation therapy have been explored as a way to try to prevent these lymphomas from coming back with a thought that the low doses of radiation might have minimal long-term brain toxicity as compared to the high doses of radiation given in the past. So this study that was presented at ASCO involved about 91 patients with primary central nervous system lymphoma. Half of them received the low-dose whole-brain radiation therapy after their tumors were treated with several months of multi-agent chemotherapy, while the other half did not get the radiation. After a follow-up period of 4 to 5 years, the results of this treatment were that the patients who received the low-dose radiation in addition to chemotherapy lived longer and had a significantly higher rate of their tumor going away and staying away at least at the 2-year follow-up tie point. Now, data is not yet available on the neurocognitive outcomes in both groups of patients. That is how well their brains were functioning with tasks like memory, calculations, and personality. The improved results seen in this group of patients who got radiation suggests that this approach may be one effective way of helping to consolidate the treatment of primary central nervous system lymphoma after the induction chemotherapy. These results, however, can only really be fully interpreted and applied once we have more long-term information on whether the patients treated in this fashion suffer from the high rate of neurotoxicity and dementia that was seen in prior studies using the higher doses of radiation. With further follow-up, this study should provide us with some definitive information on whether the strategy of adding low-dose radiation following standard induction chemotherapy is a good one for patients with primary central nervous system lymphoma. The second study I'd like to talk about was presented by Dr. Nancy Lin, again on behalf of an international group of colleagues, and described the results of a trial adding a new drug called tucatinib to a standard chemotherapy regimen of trastuzumab and capecitabine in women with HER2-positive breast cancer involving the brain. Now, many common cancers have a tendency to spread to the brain if they recur after initial treatment. This metastatic or secondary involvement of the brain occurs in over 200,000 patients a year in the U.S., and new treatments for brain metastases are desperately needed. Women with advanced breast cancer are particularly susceptible to developing brain metastases, particularly if they have the subtype of breast cancer known as HER2-positive disease. In HER2-positive disease is defined that way because of the presence of the HER2 protein on the surface of breast cancer cells. Although a number of effective treatments have been developed for patients with HER2-positive breast cancer involving the body, including some common drugs like trastuzumab and pertuzumab, these agents have not been particularly effective in either treating breast cancer that has spread to the brain or preventing the breast cancer from spreading to the brain in the first place. One of the main reasons why these chemotherapy drugs have not been effective in treating breast cancer metastases in the brain is that unlike the other organs in our bodies, the blood vessels of the brain are formed in such a way that they carefully restrict what substances in the blood are able to leave the blood and spread into the brain. Normal blood vessels in our body are somewhat leaky. And fluids, proteins, drugs can leak out of those vessels into the tissue with some freedom. The blood vessels of the brain, however, are lined by cells that tightly joined together to create a blood-brain barrier that is not leaky, and that barrier protects the brain from compounds that are circulating in our bloodstream which could adversely affect brain function if they were able to get into the brain in any concentration. Because of this barrier, most of our standard chemotherapy and anticancer drugs simply cannot cross the barrier to reach the cancer cells within the brain. In part, because of this, patients whose cancer had spread to the brain have typically been excluded from most of the clinical trials evaluating new drugs and treatments for breast cancer. The study reported by Lin at ASCO tested the ability of a new HER2-targeted drug, tucatinib, which because of its chemical structure has good penetration across this blood-brain barrier. Earlier smaller studies had suggested that this drug did indeed get into the brain at concentrations that could effectively treat breast cancer involving the brain. In this study, almost 300 patients with metastatic breast cancer involving the brain were treated with a standard chemotherapy regimen with or without the tucatinib. Serial brain scans were obtained in order to measure the response of the brain metastases to the treatment. These were typically MRI scans of the brain. The study results showed that the use of tucatinib in patients with breast cancer involving the brain reduce the risk of the growth of their brain disease by about two-thirds and improve their overall survival by at least 6 months. These results have recently been published in a more complete form in the Journal of Clinical Oncology. And these results really strongly support the use of tucatinib in combination with the standard chemotherapy regimen of trastuzumab and capecitabine in patients with HER2-positive metastatic breast cancer involving the brain. Although neither of the new approaches I've just described cure the majority of patients treated with either the primary CNS lymphoma or brain metastases from breast cancer, both describe new approaches that really potentially move us further along the road to having more effective treatments for patients with brain tumors. These studies are also outstanding examples of why well-done clinical trials that carefully test and evaluate the beneficial effects as well as the toxicities of new cancer treatments are critical to our goal of finding new therapies to treat our patients with cancer. Thanks very much. ASCO: Thank you, Dr. Lesser. Next, Dr. Michael Williams will discuss several studies that looked at new ways to treat different types of lymphoma. Dr. Williams is the Chief of the Hematology/Oncology Division and Director of the Hematologic Malignancies Program at the UVA Cancer Center. He is also the Byrd S. Leavell Professor of Medicine and Professor of Pathology at the University of Virginia School of Medicine. He is also the Cancer.Net Associate Editor for Lymphoma. View Dr. William’s disclosures at Cancer.Net. Dr. Williams: Hello. This is Dr. Michael Williams. I'm a professor of medicine at the University of Virginia hospital in Charlottesville, Virginia, where I'm chief of the hematology oncology division and the physician lead for cancer services here at UVA. I have a few disclosures, clinical trial grant support from Janssen and Pharmacyclics to the University of Virginia. I've received honoraria for medical education conferences from Xian Janssen, and I have been a consultant for Kite Pharmaceuticals in the past. So what we're going to talk about today are some of the highlights in lymphoma that were presented at the recent virtual meeting of the American Society of Clinical Oncology focused on lymphoma. So the field continues to move forward very rapidly. It's really a dynamic time for advances in treatment of lymphoma and related disorders. The exciting thing is that patients in the not-too-distant past may have had limited options, especially in the setting of recurrent lymphoma. We now have new approaches that are really quite interesting, quite effective, and I think are going to change the way we practice for these particular diseases. So the first of these I'm going to talk about is for classical Hodgkin lymphoma, also called Hodgkin's disease. So the good news is here, that the vast majority of people with Hodgkin lymphoma are cured by their frontline therapy but not all do achieve a remission, or if they do, they may relapse a year or 2 or sometimes later after their initial therapy. And these patients, historically, have not had as good of a long-term outcome as those who remained in their initial remission. So investigators from an international team of lymphoma experts conducted the KEYNOTE-204 study that compared an immune checkpoint inhibitor - it's a form of immunotherapy called pembrolizumab - versus a standard agent brentuximab vedotin, which is a drug antibody conjugate that delivers a chemotherapy agent directly to the Hodgkin tumor cells. So these were patients who had either not responded to their initial treatment, in other words were considered to be primary refractory, or had relapsed later. Many of them relapsed within 12 months, which is, again, a worrisome timing for relapse in that those patients may be more chemotherapy resistant to traditional treatments. So in this study, it was a 1-to-1 comparison of about 300 patients. And the study found that those who received the checkpoint inhibitor pembrolizumab had a better response in terms of their remission rate and a more long-lasting response than those patients treated with brentuximab vedotin. At 12 months, about 54% of patients remained in remission as opposed to about a third of patients on brentuximab. Although, there were some continued relapses over the next year, there were some patients who achieved more durable response. So it was a very encouraging finding. The side effects were as would be expected. There were some autoimmune problems with the immunotherapy checkpoint inhibitor and peripheral neuropathy in those who got brentuximab. So these investigators concluded that for patients with this form of relapsed and chemotherapy-resistant Hodgkin's lymphoma, that pembrolizumab should be considered the preferred treatment option and a new standard of care for these patients. Now, the second trial that we'll talk about relates to a specific form of non-Hodgkin lymphoma called lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia. This is a lymphoma where an abnormal immunoglobulin, a high molecular weight IgM, is produced. That can cause problems of hyper viscosity and headaches, vision changes, shortness of breath, in addition to some lymphoma-related symptoms. And what they did is compared 2 targeted agents for people who needed treatment, whether they were relapsed or had not had prior treatment at all for their Waldenstrom's. And the drugs that they chose were Bruton tyrosine kinase, or BTK, inhibitors. These are a very active class of drugs in B-cell lymphomas including Waldenstrom's. And the first of these that became available several years ago and was FDA approved is ibrutinib, and a second agent more recently approved is zanubrutinib. The latter being a bit more targeted to the molecule that we're trying to inhibit in the tumor cells. And it's similar in many ways to a third drug that's available called acalabrutinib. But in this study, they're comparing ibrutinib with zanubrutinib. And what they found is that, in about 200 patients, that both drugs were very effective in achieving a response. Slightly higher response rates for zanubrutinib, but really no significant difference in the progression-free and overall survival for these patients. So both drugs were very active and very reasonable for treating patients. There were fewer side effects, however, with zanubrutinib, in particular toxicities such as the development of atrial fibrillation and diarrhea or bruising and bleeding, which happened in a small percentage of patients on ibrutinib. So those side effects seemed to be less with the more targeted drug zanubrutinib. So they appeared to be similar in efficacy but perhaps a better safety and toxicity profile with zanubrutinib. Now, ibrutinib is approved in the United States for relapsed Waldenstrom macroglobulinemia. Zanubrutinib is approved for mantle cell lymphoma, so not for Waldenstrom. So the final entity that I want to discuss is really using a treatment that many of you no doubt have read about. There's been a lot in the news about the use of CAR T-cell, or chimeric antigen receptor T-cell therapy. So this is a form of cellular therapy. And by that, I mean that in patients who have relapsed aggressive lymphoma, usually diffuse large B-cell, a patient who has relapsed disease has T-cells. Those are part of their immune cellular defenses. And those T-cells are removed and they're genetically reprogrammed and then expanded and reinfused to patients. So they're reprogrammed so that the immune effects are targeted against the patient's lymphoma cells. So this is an approved therapy in aggressive relapsed large B-cell lymphoma. But at this meeting, investigators from a number of centers in the United States reported the interim results of a study using a CAR T-cell called axicabtagene ciloleucel, or Axi-cel, for patients with indolent or low grade lymphoma that, nonetheless, is recurring, needs treatment, and has been resistant to at least 2 or more prior therapies. So I'm going to focus in this study on the results with follicular lymphoma. They did also study a small number of patients with another type of indolent low-grade lymphoma called marginal zone. But looking at the follicular lymphoma patients, they were heavily pre-treated. Most of the patients had had 3 or more prior therapies. Most of them were refractory or, in other words, resistant to the current and the most recent chemotherapy they had received. And about a quarter of the patients had had a prior stem cell transplantation for relapsed disease but had now relapsed even after that therapy. And what they found in the first 80 follicular lymphoma patients they studied is that 95% of them responded and 81% achieved a complete remission. The duration of response was really quite good. So with a follow-up of a little over a year, about two-thirds of patients were still in remission. Whether these patients may be cured of their follicular lymphoma or may experience a later relapse is going to require more follow up, but very promising early results for this treatment of patients with otherwise resistant follicular lymphoma. There are significant side effects with this type of therapy, including something called cytokine release syndrome, which is like an intense inflammatory reaction. Fortunately, the severe forms of this occurred in a minority of patients, under 10%. There can also be neurologic events that can range from tremor or confusion, and rarely even patients becoming unresponsive. Fortunately, most everyone recovers from this. And in this trial, the more severe forms of these neurologic events occurred in about 15% of patients. So a very promising early set of data for another group of lymphoma patients, in addition to those with large cell lymphoma. So if you are in a situation of highly resistant and progressing follicular lymphoma, including follicular lymphoma that may have transformed from the lower grade into a higher grade large cell lymphoma, then considering a CAR T-cell therapy or a clinical trial of other novel approaches is certainly worth considering. And I'll finish by just saying that it's a fast-moving field. There's a lot of benefit if you have a newly diagnosed or a relapsed lymphoma to talk with your oncologist and consider whether a second opinion may be in order and what clinical trials might be relevant for your situation because, nowadays, we often find that taking part in such a trial provides access to some of these very promising new agents and allows us to move the field forward and bring these newer treatments online so that they can benefit as many patients as possible. So a very exciting time in the field of lymphoma, lots of important new data presented at ASCO, and I'll look forward to updating you on future advances in another podcast.

ASCO would like to thank Dr. Williams for discussing this research. Dr. Williams: Hello, and thanks for joining us for this podcast. My name is Michael Williams. I'm Professor and Chief of Hematology/Oncology at the University of Virginia in Charlottesville. And I'm pleased to discuss some exciting advances in lymphoma that were presented at the American Society of Hematology meeting held in Orlando in December 2019. My disclosures are that my research group here at the university, through the university, has received research support from pharmaceutical companies AbbVie, Pharmacyclics, and Janssen, and I have received honoraria for speaking at conferences from Xian-Janssen in China. So what I'm going to talk about today are 2 reports about the management of localized diffuse large B-cell lymphoma, an update on a novel therapeutic approach for relapsed mantle cell lymphoma. And then, I'll finish with a brief introduction of an agent that is showing promise for treating highly resistant relapsed lymphoma that was presented in the plenary session during the ASH meeting. So let's start with localized diffuse large B-cell lymphoma. So DLBCL is the most common subtype among the many forms of non-Hodgkin lymphoma. Usually, people present with advanced stage disease. But as many as 25 to 30 percent may have a disease that's localized to just 1 site or a very localized area of lymph nodes, so these would be stage I or stage ll patients. And the first report that I'll comment upon was presented by Dr. Laurie Sehn at the BC Cancer Agency in Vancouver, British Columbia. So they did a retrospective review looking at 319 patients treated in British Columbia over the past 15 years. So these were patients who had a nonbulky mass, they were localized disease. And the treatment currently for this disease is that people get either 6 cycles of a regimen such as rituximab and CHOP chemotherapy or more limited chemotherapy. Typically, 3 cycles of R-CHOP followed by radiation therapy. The importance of this study is that it is exploring a mechanism to de-escalate therapy, if you will, by avoiding the use of the radiation therapy. So what they did, is patients with localized disease received 3 cycles of rituximab plus CHOP therapy and then underwent a PET scan. So PET scans, unlike CT scans, are nuclear-medicine imaging that shows the functional uptake of radioactive glucose by the sites involved by lymphoma. So if you become PET negative after the three cycles of rituximab, CHOP therapy, then it seems likely that you've got a very highly responsive disease, and you may be able to avoid radiation therapy. So they did the PET scan after 3 cycles, and for those who were PET negative, then those patients received 1 additional cycle of rituximab CHOP, and that was the end of their therapy. If they were still PET positive, then they moved on to radiation therapy to the involved area. So what they found was quite interesting that of the 319 patients, 254 were negative after their PET scan. And so went on, virtually all of them, to just getting 1 more cycle of rituximab CHOP as planned. The outcomes for those patients were that very few of them relapsed over the next several years. They followed patients now, for about four years or more, in most cases, and they found that the overall, 5-year progression-free survival was 88% for those who were PET negative. For the subset of patients who were still PET positive, and got the radiation therapy, their outcome was somewhat worse, in that there was only 74% who were still progression free. The overall survival for these patients was 90%, at 5 years, for those who were PET negative and 77% for PET positive. So what this study shows us, is that a PET scan after 3 cycles, can inform us about patients who are 90% likely to have good control of their disease, with just 4 treatments, and you can avoid the exposure to radiation therapy. Those who were still PET positive still did well: 3 out of 4 were still in remission beyond 5 years but not quite as good an outcome. So these are patients who may be candidates for an alternative approach to try to do better with their long-term cure rates. So that leads us to the second presentation that I want to discuss. This was presented by Dr. Daniel Persky on behalf of the Southwest Oncology Group, which is part of the National Clinical Trials Network, in the United States. So they had a very similar approach. They studied patients with localized Stage 1 or 11, nonbulky diffuse large B-cell lymphoma, and they got standard rituximab CHOP therapy, and then a PET scan after the third cycle. Just as in the paper I discussed from British Columbia. Those who had negative PET scans got one additional cycle of rituximab CHOP. Those who were still PET positive got involved-field radiation therapy and treatment with a radio-labeled monoclonal antibody. Essentially, a radioactive form of rituximab, which has given us a single dose about a month after they'd finished their involved-field radiation therapy and then they got a follow-up PET scan, thereafter. So this study went on for several years, at multiple sites around the country. They enrolled 132 patients, and of those patients, 110 were PET negative after their third cycle. So only 18 needed to go on to this additional radiation therapy and the systemic treatment with the radio immuno therapeutic called Ibritumomab tiuxetan. They followed these patients now for 4 and a half years, and only 5 patients have progressed, and only 2 have died of their lymphoma. So of those who progressed, 3 of them had gotten just the R-CHOP alone. There was another patient who was PET positive but declined getting the radiation therapy who progressed. And then, another patient who had only 1 treatment was rituximab CHOP but then went off treatment due to toxicity. So similar, and in fact, almost identical to the British Columbia report. Five-year freedom from progression of their disease was 87%, and the overall survival was 90%. So these patients can do quite well, since many times, the location for localized DLBCL is in the head neck. There can be significant late effects of radiation therapy. So I think these studies reassure us that patients with localized disease can have very durable outcomes and cure rates. It's important to note that there's a higher rate of late relapse beyond three years in patients with localized DLBCL compared to more diffuse extensive disease suggesting that there may be some differences in the biology of a localized disease. So very important data, and data that gives us the opportunity to de-escalate treatment in localized large cell lymphoma. So let's switch gears and talk about mantle cell lymphoma. There's been a lot of progress in this disease over the past decade. Much of it related to the use of nonchemotherapy targeted agents such as Bruton’s tyrosine kinase inhibitors including ibrutinib and the Bcl-2 inhibitor, venetoclax. There was a study reported last year by an Australian group led by Dr. Constantine Tam. This study was updated at the ASH meeting with a longer follow up. So these were patients with Relapsed/Refractory disease, heavily pretreated. Many of them, previously, having had intensive chemotherapy and a stem cell transplant. And half of them had mutations in a gene called TP53, which is correlated with frequent chemotherapy resistance and high relapse rate. And what they found by combining the targeted agents ibrutinib and venetoclax, that they got very high response rates. The majority of patients responded although, there were a few who were primarily resistant, and about a third of patients, actually, got very deep remissions. PET negative and negative for minimal residual disease detection. If you look at the subset, of the highest risk patients, with the TP53 mutation, half of them achieved a complete response rate, and some of these patients have had durable responses. There have been a few patients who've had deep responses, who've been able to come off treatment. And overall, the duration of response at 2 and a half years is 74%. But what this study shows us, is yet again, that these novel targeted drugs that are typically better tolerated than cytotoxic chemotherapy can have very good and indeed dramatic responses, and so is showing a lot of promise. It reminds us that in mantle cell, whether it's newly diagnosed or relapsed, that talking to your oncologist about clinical trial opportunities can often avail you of some of the most promising new approaches. And indeed, that's true for all forms of lymphoma, that clinical trial options should be part of the discussion with treatment planning. I'm going to finish by just mentioning another novel agent that is being applied to patients with highly resistant relapsed disease. This is a molecule called mosunetuzumab, and this is a bispecific antibody. So there are a number of these now that are in clinical development, and some are FDA approved for treating leukemias and certain lymphomas. This one is designed to basically connect a body's immune system, the T cells, with the B-cell lymphomas by using an antibody that can recognize each of those and bring them physically together. So this was presented by Dr. Steven Schuster; it was a multinational study of this bispecific antibody in patients with very aggressive relapsed/refractory lymphomas including, diffuse large B-cell and transformed follicular lymphoma. And what they found in this study, is that response rates were 64%, with 42% of patients achieving a complete remission. So it's still early, but quite promising because these are patients who had failed CAR T-cell therapy. They may have failed transplant, or they were patients who needed a treatment to bridge them over to get to a CAR T or another treatment such as an allogeneic stem cell transplant. The toxicities were generally manageable and similar to those seen with other bispecific antibodies. So it's early, but across subtypes of patients with aggressive and relapsed lymphoma, I think this is another promising molecule, that may well provide good therapeutic options via a clinical trial for patients who have very limited other options to manage their disease. So thanks again for joining this podcast. There was a lot of other exciting data that we didn't have time to go through, so I encourage you to continue learning about what's new in the field, discussing with your oncologist, or with a consulting specialist in lymphoma, to make sure you can avail yourself of the best in current diagnostics and therapeutics.

Leavell Professor of Medicine and Professor of Pathology at the University of Virginia School of Medicine. ASCO would like to thank Dr. Williams for discussing this topic. Dr. Williams: Hello. This is Michael Williams. I'm a professor at the University of Virginia Health System in Charlottesville, Virginia, and I'm reporting today on some exciting advances in lymphoma that were presented at the Annual Meeting of the American Society of Hematology, which was held in San Diego, California in early December 2018. Well, there were a number of areas of lymphoma that had important reports, and I'm going to just give you a small sampling of these today. We'll start with a new treatment option for patients with follicular lymphoma. Traditionally, this type of lymphoma, when it's symptomatic and needs therapy, the treatment of choice has been chemotherapy combined with a monoclonal antibody such as rituximab or obinutuzumab. But investigators, in a multicentered trial, decided to test whether you could use a chemotherapy-free treatment approach for patients like this by using rituximab combined with lenalidomide, which is also known as Revlimid, as a substitute for chemotherapy. And this is based on the fact that Revlimid plus rituximab has synergistic activity in patients with relapsed disease, so maybe we could see acceptable, high responses when it would be compared directly with rituximab plus chemotherapy. So the way the trial worked is this. Patients who needed therapy, who had advanced-stage follicular lymphoma—they had never had any therapy before—were randomized to either the rituximab-lenalidomide combination or a rituximab-chemotherapy combination that could include the regimens CVP or cyclophosphamide, vincristine, prednisone, the same combination given with daunorubicin, or the CHOP regimen, or rituximab combined with bendamustine. So over 1,000 patients were treated in this multinational study and the goal of the treatment, of the study was to prove that, actually, the ritux-lenalidomide was superior to the chemotherapy regimens. So the results showed, not superiority, but comparability. The complete remission rate between rituximab-len and ritux-chemotherapy were really identical, 48 and 53 percent, and the 3-year likelihood that the patients were progression-free, so had had no recurrence of their disease, was identical as well: 77 to 78 percent. There was no difference in survival which was 94% at 3 years in both arms. The toxicities differed, however. There was more rash with the lenalidomide combination, whereas low blood counts and the need for growth factor support such as G-CSF was greater with chemotherapy. And it was also interesting that some of the traditional risk factors didn't seem to apply, as much, for lenalidomide. So what would be considered higher risk patients treated with chemotherapy, seemed to do somewhat better with the lenalidomide combination. The importance for a patient with untreated follicular lymphoma who needs therapy is that a chemotherapy-free approach with rituximab plus lenalidomide can be considered equivalent to rituximab-chemotherapy. It’s worth discussing this with your oncologist when you're considering what treatment to use initially. The next subtype of lymphoma that I want to discuss is diffuse large B-cell lymphoma, and there's 2 presentations that I'm going to summarize. One, in patients with advanced stage disease, meaning stage III or IV. This identifies patients who have disease both above and below the diaphragm, to make it stage III, or stage IV means they've got bone marrow or other sites of involvement such as liver or bone. And the question being asked in this trial, which was part of the International GOYA trial, will take just a moment to explain. So the original GOYA trial compared whether a newer form of anti-CD20 monoclonal, namely obinutuzumab, which is also called Gazyva, how that would compare with the standard established monoclonal antibody, rituximab. And the initial findings of this study found that there was no benefit for the newer antibodies. So rituximab and CHOP chemotherapy was equivalent to obinutuzumab and CHOP chemotherapy in overall outcomes. But there was an opportunity with this trial to answer a question that's been out there for many years, and that is how many cycles of treatment does one need? So the investigators took advantage of this large study which included 712 patients who were randomized to rituximab plus CHOP. Just over 500 of them received 6 cycles, and the remaining 186 received 8 cycles. Even the patients who got 6 cycles of CHOP chemotherapy also got an additional 2 doses of rituximab, so the immunotherapy monoclonal antibody was equivalent between the 2 arms. And the results of this showed that there was really no difference at all with a followup of about 3 years. Response rates were equivalent and there was no difference in the patients staying in remission. It didn't matter in terms of survival which was excellent in both arms. There was, however, more toxicity in patients who received 8 cycles, including cardiac problems, infections, etc. These results showed that, I think we can finally put to rest the use of 8 cycles of rituximab-CHOP chemotherapy for advanced-stage large cell lymphoma. It's been an unknown entity because we never had a direct comparison of these. So we can now say that 6 cycles plus the additional 2 doses of rituximab is a standard for advanced-stage diffuse large B-cell lymphoma. Now, what about patients who have limited-stage, so stage I or II diffuse large cell lymphoma? That means just a single lymph node area's involved or 2 adjacent lymph node areas. In the past, these were treated either with 6 cycles of rituximab-CHOP or sometimes cycles of R-CHOP plus local radiation therapy. And in this study, which took a long time to complete; it began in 2005, but it enrolled 592 patients who were then randomized to either 4 cycles or 6 cycles of treatment. Radiation therapy was not planned for any of these patients except for very specific locations of involvement such as testicular DLBCL where radiation therapy is a standard. So the take-home message after over 5 years of follow-up for patients on this study showed that 4 versus 6 were identical. So 89% of patients were still in remission at 3 years after completing treatment, and the overall survival was really impressive, 98 to 99 percent in the 2 arms. So there was no benefit with limited-stage favorable disease. Now, who are these patients? So younger than age 60, stage I or II disease, and normal LDH. They did not have bulky disease, meaning there was no nodal mass more than 7 and a half centimeters. So if you fit those criteria, then you can benefit from a de-escalation of treatment and be spared the additional 2 cycles of R-CHOP. Now, sticking with the topic of diffuse large B-cell lymphoma, a challenging problem in our field is for patients who relapse after their initial therapy, or in some cases, fail to respond to a treatment like rituximab-CHOP or an equivalent immuno-chemotherapy regimen. And a very exciting advance in the field, over the past few years, has been the development of chimeric antigen receptor T cells or CAR Ts. Traditionally, what we've done with patients who relapse or have resistant diffuse large cell lymphoma is to give them a second-line, high-dose chemotherapy regimen, and if they showed a good response to that, they could then go to a dose-intensive treatment with a follow-up consolidation by autologous stem cell transplantation. And with that, you can cure, overall, about 40% or so of patients. The CAR T-cell approach takes a very novel immunotherapy effort, and that is that a patient's own T-cells are removed from the peripheral blood, and then in the laboratory, they're modified and reprogrammed so they can attack the patient’s diffuse large B-cell lymphoma cells that are resistant to chemotherapy. So there were 2 important follow-up studies, each of them involved 1 of the agents, the CAR T-cell products, that are approved by the Food and Drug Administration for patients with relapsed or refractory diffuse large cell lymphoma. The first used the CAR T known as axicabtagene ciloleucel. It's quite a complex name, but it goes by the abbreviation of axi-cel or the trade name is Yescarta. So in this study, the investigators wanted to show that this is a treatment that can be extended to many centers with the product, the CAR T being made in a central facility by the pharmaceutical company. So it was a retrospective study of 295 patients at 17 international centers: a lot of patients across a broad spectrum of sites in North America and Europe. Virtually all the patients were able to develop and obtain a CAR T product. It included patients with some of the higher risk forms of the DLBCL such as double and triple-hit lymphoma. About 3% of patients died during the treatment, although only 1% of these were felt to be related to the treatment itself. The response rates were quite good, with about 80% of people responding. The complete remission rates at 30 days after the CAR T infusion were 47%. So it proved that you can use this centrally manufactured product. So the patients T-cells are collected at the local center, they're shipped to the manufacturing facility, the CAR Ts are generated, sent back to the home institution, and then infused. And I'll say a word in a moment, after I introduce the next paper, to explain some of the side effects of this treatment. So the second study was also presented at the ASH meeting and published simultaneously in the New England Journal of Medicine in early December 2018. So this used the second FDA approved CAR T known as tisagenlecleucel or Kymriah. In this study, there were 93 patients who were able to receive a CAR T-cell infusion, 40% of them achieved a complete remission, and another 12% had a partial response. And that a year after their documented response, two-thirds of these patients were maintaining the response, including 79% of those who achieved a complete remission. So this trial again confirmed across multiple centers that CAR T-cells can be an effective therapy. The side effects of both of these drugs can include something called cytokine release syndrome where the immunologic effects, essentially, release cytokines into the blood that can mediate a capillary leak, respiratory troubles, and low blood pressures, that can, in some cases, require intensive care unit support. This can be managed by other mediators that tamp down the cytokine effect such as an interleukin-6 antagonist. The other toxicity which is less well understood and problematic can be neurologic effects which can include confusion, speech alterations and even coma. But again, approaches and treatments to identify and manage this are being developed. So CAR Ts have become established. They're available at a number of centers, but it's important to consider this as a treatment option in the setting of relapsed or refractory diffuse large cell lymphoma. The long-term curability is still unknown, although it's encouraging that patients with very resistant disease who'd get a good response can maintain that response out to a year and more. So we're going to be very interested to see how the longer-term follow-up comes together. The final topic I wanted to mention today is Waldenstrom macroglobulinemia. So this is a unique form of indolent B-cell lymphoma where the lymphoma cells release a monoclonal immunoglobulin into the blood known as IGM. Now, IGM is a very large antibody, and because of that, when the levels are very high, patients can have problems with high viscosity or thickening of the blood, which can cause confusion, vision changes, sometimes respiratory problems. And these patients also can become anemic or develop enlarged lymph nodes or enlarged spleen. So one of the standard treatments for this disease is, again, the immunotherapy monoclonal antibody rituximab, but the responses are typically incomplete and somewhat short-lived. So it was exciting, a couple of years ago, when the targeted tyrosine kinase inhibitor, ibrutinib, which targets the bruton tyrosine kinase in malignant B-cells. This is an agent that's approved in chronic lymphocytic leukemia, and certain lymphomas such as mantle cell, marginal zone, as well as lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia. So here's the study. Investigators had shown that if you combine rituximab with ibrutinib, that the response rates were improved as compared with rituximab by itself. And in a follow-up study that looked at this over a longer period of time, these benefits of the combined therapy were confirmed. These included patients without prior treatment or with prior treatment, with either chemotherapy or rituximab. And there was a confirmed benefit for the ibrutinib-rituximab combination in patients, whether they had had treatment before or not, and regardless of certain genetic markers that we use to assess risk in Waldenstrom. It was also shown that because these treatments continue indefinitely, as long as patients are responding and tolerating therapy, that the response rates improved over time. The side effects of treatment with ibrutinib are well-known, now, after several years of use across a variety of diseases, as mentioned, and include diarrhea, sometimes rash. You can see problems with easy bruising or bleeding, atrial fibrillation, and sometimes skin rash, or muscle and joint aches. But most patients are able to continue therapy and to benefit from it over an extended period of time. So the combination of ibrutinib plus rituximab was shown to add benefit compared with rituximab alone, and again, is a treatment approach and option that you could consider whether you have previously untreated or relapsed Waldenstrom macroglobulinemia. So overall, it was a very exciting meeting. We've had practice-changing data presented, and I've given you just a sampling of those. I think it's important for anyone dealing with lymphoma, or related malignancy, such as CLL or multiple myeloma to be very encouraged by the progress in the field, the opportunity to get much better responses with less toxicity and with minimal or no use of traditional chemotherapy. So we're pleased to be able to offer these treatment approaches for our patients. And I thank you for your taking part in the podcast and hope you found it useful. Thanks again.
