Alexandra Rojek: Hello and welcome to JCO Article Insights. I'm your host, Alexandra Rojek, and today we will be discussing an original report published in the June 10th issue of JCO titled, “Anti-CD19 Chimeric Antigen Receptor T-Cell Therapy for Richter Transformation: An International, Multicenter, Retrospective Study,” by Kittai et al. This report addresses the real world efficacy of CAR T-cell therapy for patients with Richter transformation of CLL to large B cell lymphoma, which represents a high risk group of patients with an unmet need for novel and more effective therapeutic agents than are currently available. Richter's represents the transformation of chronic lymphocytic leukemia, or CLL, to an aggressive lymphoma, most often a large B cell lymphoma, most similar to diffuse large B cell lymphoma or DLBCL. Treatment for Richters is often modeled after treatment practices for DLBCL. However, there's no clear standard of care and outcomes for these patients lag behind those of large B cell lymphoma patients otherwise.
An important advance in recent years in the DLBCL field is the approval of anti CD19 CAR T-cell therapy in the second and third line settings. However, patients with Richter transformation were largely excluded from these pivotal trials. This study in JCO thus set out to address what the real world outcomes were for patients with Richters who were treated with CAR T-cell therapy across 12 centers internationally. The study included 69 patients across these twelve sites, with a median age of 63 years at diagnosis of Richters and a median of six years after initial CLL diagnosis. Included patients received a median of four prior lines of therapy for either CLL or Richters, with a median of two prior lines of therapy for Richters, although two patients had not received any prior therapy for their Richter transformation.
The most recent prior treatments included chemoimmunotherapy in 29% of patients, followed by BTK inhibitors in 19%, as well as combinations of BTK inhibitors and BCL2 inhibitors in 12%. 17% of patients had not received prior therapy for their CLL before their diagnosis with Richters, 58% of cases had known TP53 mutations at time of transformation, and 41% exhibited deletion 17p by FISH. Prior to receiving CAR T-cell therapy, 86% of patients required additional bridging therapy, most commonly with a BTK inhibitor or chemoimmunotherapy. A diverse set of commercial CAR T-cell products were represented in this study, with the majority of patients at 64% receiving axi-cel, 25% receiving tisa-cel, 10% receiving liso-cel, and one patient received brexu-cel in an investigational setting. Median time from apheresis to CAR T infusion was 34 days, and 59% of patients continued on a BTK inhibitor throughout CAR T-cell therapy.
When we move on to look at responses, 66 out of 69 patients were available for response. Three patients died related to adverse events after infusion and before response assessment, with the best overall response of complete response or CR in 46% of patients and partial response or PR in 17% for an overall response rate of 63%. With a median follow up time of 24 months, the median PFS in the study was 4.7 months and the median OS was 8.5 months. For those who achieved a CR, the median duration of response was an impressive 27 months, and for those achieving PR, the median duration of response was only two months. The two year PFS rate was thus 28%, and the two year OS rate was 38%. Four patients who achieved a CR went on to receive an allogeneic stem cell transplant. Among those whose disease progresse

Dr. Shannon Westin and her guest, Dr. Bryan Schneider discuss the article “ECOG-ACRIN EAZ171: Prospective Validation Trial of Germline Predictors of Taxane-induced Peripheral Neuropathy in Black Women with Early Stage Breast Cancer” recently published in the JCO and presented at the 2024 ASCO Annual Meeting.

Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth on manuscripts published in the Journal of Clinical Oncology. I am your host, Shannon Westin, GYN Oncology Extraordinaire and also the Social Media Editor of the Journal of Clinical Oncology. And it is my great pleasure to present some really incredible work today that is going to be a dual publication in the Journal Clinical Oncology and a presentation at the American Society of Clinical Oncology Annual Meeting on Monday, June 3. And this is the “ECOG-ACRIN EAZ171: Prospective Validation Trial of Germline Predictors of Taxane-induced Peripheral Neuropathy in Black Women with Early Stage Breast Cancer.”
And I am joined today by the senior author on the presentation and the primary author on the manuscript, Dr. Bryan Schneider. He is the Vera Bradley Professor of Oncology, the Professor of Medicine and Medical Molecular Genetics at the Indiana University Melvin and Bren Simon Comprehensive Cancer Center in Indianapolis.
Welcome, Dr. Schneider.
Dr. Bryan Schneider: Dr. Westin, thank you for having me on today.
Shannon Westin: We're so excited and we're really excited to really summarize this incredible work that's being presented today. So, first, let's just levelset. Can you speak a little bit about peripheral neuropathy and the most common causes in patients with cancer?
Dr. Bryan Schneider: Yeah, I mean, I think for those of us who treat patients using the taxanes, we recognize probably one of the most important and common side effects that we deal with is peripheral neuropathy, and one that can, I think, impact both quality of life, but also impacts the ability to maintain dose intensity. When we think about risk factors for neuropathy, historically, I think obesity has been reported as a potential risk factor, as has diabetes and other conditions which put people at risk for neuropathy.
Shannon Westin: And prior to your work that you'll discuss with us today, what do we know about the incidence of peripheral neuropathy in patients that identify as black?
Dr. Bryan Schneider: Yeah. So, interestingly, I think we've recognized that patients who self identify as black have disparate outcomes in terms of inferior survival and more aggressive subtypes of breast cancer, like triple negative breast cancer. But I think the idea of toxicity being a disparate factor as well is probably a more recent one. Interestingly, as we set out to identify biomarkers to predict outcomes in the large adjuvant trial E5103, we weren't really setting out to look at this by race. We were using at that time, genome-wide approaches to identify biomarkers for toxicity and also efficacy. But what was interesting as we did that one of the most important predictors, as we looked across a number of important toxicities, was ancestry. And really the science spoke to us, it was very clear that patients of African ancestry had higher rates of bev-induced hypertension, anthracycline-induced cardiomyopathies and also peripheral neuropathy.
Shannon Westin: That's so interesting. We have so much overlap in gynecologic oncology and breast cancer. And I don't know that I've ever seen work like this. And now it's making me very intrigued and making me want to move forward to that.
Can you talk a little bit more about this ECOG-ACRIN E5103, like briefly about the study and what it demonstrated specifically?
Dr. Bryan Schneider: Yeah. So E5103 was an adjuvant breast cancer trial that really set out to look at the impact of bevacizumab in the curativ

Alexandra Rojek: Hello and welcome to JCO Article Insights. I'm your host, Alexandra Rojek, and today we will be discussing a clinical trial update published in the May 10th issue of JCO addressing the long term follow up of the addition of romidepsin to CHOP chemotherapy for previously untreated peripheral T-cell lymphoma, or PTCL. This report by Camus et al discusses a five-year follow up of the original Ro-CHOP trial, which did not meet its primary endpoint of progression free survival. The original Ro-CHOP study, conducted by the LYSA group, was published in 2021 in JCO and was conducted as a one-to-one randomized phase III study of Ro-CHOP versus CHOP for patients aged 18 to 80 years with PTCL. 98 international centers were included, and the study enrolled patients between 2013 and ‘17. Nodal follicular helper T-cell, or TFH lymphoma was defined in this study follow-up as a PTCL expressing at least two of five TFH markers according to the latest classifications. The study's primary endpoint was PFS with secondary endpoints of OS and duration of response, or DOR. Five year follow up was reached in December 2022.
In the original study report, the addition of romidepsin to CHOP did result in a reduction of dose intensity of chemotherapy. However, in this updated follow up, there were no new safety signals reported. A total of 421 patients were enrolled in the trial with a median age of 65 years. Notably, those who were randomized to the Ro-CHOP arm had a higher proportion of IPI 4-5 scores at 33%, versus 24% of those who were assigned to CHOP alone despite randomization. Nearly half of patients carried a histologic diagnosis of angioimmunoblastic T-cell lymphoma. 30% were characterized as PTCL NOS, not otherwise specified, 10% ALK negative anaplastic large cell lymphoma, leaving 13% reported as other. Over 60% of patients had stage four disease at enrollment, with nearly half having more than two sites of extranodal involvement. Median follow up was six years with a median PFS of 12 months for Ro-CHOP and 10.2 months for CHOP, which did not reach statistical significance as reported in the original study publication. Estimated five year OS available as a part of this clinical trial update was 50% for Ro-CHOP and 43% for CHOP alone, and also did not reach significance. There was, however, a longer duration of response observed in the Ro-CHOP arm at 52 months versus 24 months for CHOP, which is a new finding in this extended follow up of the study.
In an effort to better understand whether there are subgroups which may benefit from romidepsin despite the overall negative outcome of this study, the authors are able to provide new insights from this Ro-CHOP study in line with our current and updated understanding of PTCL. When the authors evaluated the study population for subgroups which may benefit from addition of romidepsin, TFH lymphomas, which included angioimmunoblastic, follicular, and NOS subtypes, were noted to have an improved response to the addition of this HDAC inhibitor. This subgroup, numbering 201 patients, experienced a mean PFS of over 19 months with Ro-CHOP versus over 10 months for those who received CHOP, and this difference achieved statistical significance. Similarly, there was a higher complete response rate and longer duration of response for those in the TFH subgroup who received romidepsin.
The authors also make note that those patients in this subgroup with high IPI appeared to particu

Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we go in depth on manuscripts and research published in the Journal of Clinical Oncology. I am your host, Shannon Westin, Social Media Editor for JCO and a Gynecologic Oncologist by trade. I am thrilled today to present Methylphenidate Versus Placebo for Treating Fatigue in People with Advanced Cancer, a Randomized, Double-Blind, Multicenter Placebo-Controlled Trial. This manuscript is a dual publication in the Journal of Clinical Oncology and presentation at the European Association of Palliative Care Congress here on May 17, 2024.  
And to review this incredible research with us will be Professor Patrick Stone, the Head of Department of Marie Curie Palliative Care Research Department, Division of Psychiatry at University College London. Welcome, Dr. Stone.
Dr. Patrick Stone: Thank you very much. Thank you.
Shannon Westin: Let's get right to it, we’ll level set. Can you speak a bit about the definition of cancer-related fatigue and how common it is in people with advanced cancer?
Dr. Patrick Stone: Sure. I think fatigue is a difficult thing to nail down really and define it clearly, and there are lots of definitions out there. In many ways, the simplest definition is the EAPC, the European Association of Palliative Care's definition of just a subjective sensation of weakness, feeling tired, and exhaustion. The reality is that that symptom is very common in the general population. And so if you really want to get a handle on it, I think a good way to do it is to think about taking an operational definition and say, “Look, if fatigue is normally distributed approximately in the general population, then we should consider severe fatigue or pathological fatigue could be defined as fatigue that is worse than 95% of the general population. And if you think that definition, then prevalence of fatigue in patients with newly diagnosed breast or prostate cancer, for instance, is around 15%, so three times as common as the most severe fatigue in the general population. If you come to patients with newly diagnosed non-small cell lung cancer, it’s up to about 50%. And if you come to my area, which is palliative care and you go to a hospice and you ask people to complete a fatigue questionnaire, 78-80% of people complain of fatigue that is more severe than 95% of the general population. So that I think gives us a good handle on sort of the severity of this problem in cancer patients and how it progresses as disease progresses.
Shannon Westin: I love this because I think we always struggle with exactly how to nail down the definition and exactly how to treat it. So I think that it’s a really nice transition to existing treatment options for this issue and exactly how they might work.
Dr. Patrick Stone: The first thing to say is in medicine if you can find a cause then you give a treatment directed at the cause and obviously that applies to fatigue as well. So the first thing is to do a thorough assessment of your patient, and if you can find an easily remediable cause such as anemia, hypocalcemia, or hypomagnesemia, or maybe other things like depression, which might manifest as fatigue, then you should try and give a treatment directed at that cause. But, for many patients, there won't be a single clearly identifiable cause you can target.
And then people use more broad spectrum approaches if you like. The most well-studied I think is exercise. And exercise, there have been lots of randomized controlled trials in different types of exercise and it’s a well attested treatment, which I

Dr. Jonathan Friedberg: Hello and welcome to another episode of JCO After Hours. I'm your guest host, Jonathan Friedberg, Editor in Chief of JCO, and today we have a very special episode with Pamela Kunz, Associate Professor of Medicine in the Division of Oncology at Yale School of Medicine and Yale Cancer Center. As the new editor in chief of JCO Oncology Advances, she is with us today to share a new opportunity for authors to submit to ASCO’s new online open access journal.  
Pam, welcome.
Dr. Pamela Kunz: Thank you.
Dr. Jonathan Friedberg: I guess my first question to you is, why did you take this role of editor in chief? People have asked me the same question, and I'm still, I think, trying to figure out the answer. So how did you decide to do this?
Dr. Pamela Kunz: That's a great question, and I might ask you the same thing. I think as I've gone on in my career, I really like saying I think about what I say yes and no to, and like saying yes to things that I think can make a difference and have real impact. And as a clinical trialist and someone who really hopes to advance the field scientifically, I think it was really exciting to think about helping to craft the future of the science of oncology and to also do it in a way, as we will later talk about open access, but do it in a way that really thinks about a broad audience, because open access really requires us to think about meeting the needs of our audience, as the articles will likely have broader reach.
Dr. Jonathan Friedberg: So, I mean, I can say I'm very excited about this journal. We do have a number of outstanding papers that we're not able to accept at JCO and knowing that there'll be a good home for these papers is heartwarming for me.  
Can you tell me a little bit about your vision and goals for this journal? You're really starting with a blank palette. It must be exciting to try to craft what this is going to be about. 
Dr. Pamela Kunz: It is really exciting. It's a little scary, I'll be honest, to have a blank slate, but I'm appreciative of you and the other editors in chief and staff for helping to provide some guidance. I think that in the beginning, as you were speaking to, there's an opportunity for us to really keep some great science in the JCO family. And so at least early on, we're hoping to really attract and think about publishing some earlier phase trials that may not quite meet the bar of getting published in JCO. So, phase I, phase II trials, even secondary analyses that yield important data from some of the larger phase III trials. This will be an evolution, I think, also. I think that what we may look like this year may look a little bit different in future years, but at least initially, we'll be focusing on some of the earlier phase clinical trials. I'm now framing this around beyond the clinical trial of secondary analyses quality of life, PROs. One thing that's exciting, a new article type will be plain language summaries. So really interpreting the clinical trial for patients and the lay public, I think that's an initial way that we're going to be thinking about it.
Dr. Jonathan Friedberg: And who do you see as the audience for this journal?
Dr. Pamela Kunz: Well, the opportunity that we have with open access is that we really have a much broader audience than we will have had historically with some of the non-open access journals. And I think that means that we have an obligation to be thinking about who that audience is. So, it's a great question. I think our audience will certainly be some of our typical readers, really, the oncology scientific community, but it will likely also be other physicians, primary care physicians, commun

In this JCO Article Insights episode, Rohit Singh provides summary on two articles published in the April 10th issue of the Journal of Clinical Oncology. The first article, "Phase III, Randomized Study of Atezolizumab Plus Bevacizumab and Chemotherapy in Patients With EGFR- or ALK-Mutated Non–Small-Cell Lung Cancer (ATTLAS, KCSG-LU19-04)" describes a randomized, open-label, multicenter, phase III study evaluating the efficacy of atezolizumab plus bevacizumab, paclitaxel, and carboplatin (ABCP ) in EGFR- or ALK-mutated NSCLC that progressed before TKI therapy. The second is the accompanying Oncology Grand Rounds.

Dr. Rohit Singh: Hello and welcome to JCO Article Insights. I'm your host, Dr. Rohit Singh. Today I will provide a summary of a Phase III, Randomized Study of Atezolizumab Plus Bevacizumab and Chemotherapy in Patients With EGFR- or ALK-Mutated Non–Small-Cell Lung Cancer (ATTLAS, KCSG-LU19-04), by Dr. Park and colleagues from Seoul, Korea. The purpose of this study was to evaluate the efficacy and safety of the ABCP regimen based on IMpower150 in patients with EGFR or ALK mutated non-small cell lung cancer who had progressed on prior targeted treatment.  
I will also discuss an Oncology Grand Round case titled "Management of Treatment Resistance in Patients with Advanced EGFR Lung Cancer: Personalization, Parsimony, and Partnership", by Dr. Vallillo and colleagues from Lahey Hospital Medical Center and Tufts University School of Medicine, Boston, Massachusetts. Oncology Grand Round cases help us to give a clinical context to the clinical trial.  
While TKIs are the established standard of care for non-small cell lung cancer harboring driver mutations, most patients will develop resistance to these treatments. Immune checkpoint inhibitors, with or without chemo, have shown clinical benefits of immune checkpoint monotherapy in patients with EGFR-mutated non-small cell lung cancer. Consequently, platinum-based chemo is the standard of care for patients with EGFR TKI failure. This was a phase III, multicenter, open-label, randomized trial conducted at 16 hospitals across the Republic of Korea. Patients diagnosed with stage four non-small cell lung cancer with sensitizing EGFR mutation or ALK translocation were included in the study. Patients were randomly assigned to the ABCP arm or chemo-only arm in a 2:1 ratio. Eligible patients were stratified on the mutation type (EGFR mutation vs. ALK translocation) and the presence of brain metastasis. No crossover to atezolizumab was permitted. 
The recruitment with T790M mutation was capped at 30%. Patients who responded continued to receive maintenance with atezolizumab until disease progression or unacceptable toxicities occurred. If a patient was identified to have an acquired T790M mutation after the failure of a first or second-generation EGFR TKI, the patient had to be treated with a third-generation EGFR TKI before enrollment. The primary endpoint was investigator-assessed objective response rate according to research criteria. The secondary endpoints included overall survival and progression-free survival at one and two years, and the duration of response, along with a safety analysis. Investigators also did an exploratory biomarker analysis based on PD-L1 expression and its correlation with the response. They also analyzed the distribution of tumor-infiltrating lymphocytes, and a cut-off of 20% inflamed score was used to compare the two arms. Overall, 228 patients were enrolled, 154 in the ABCP arm and 74 in the chemo-only arm. Most patients were female at 56.1% and never smokers at 62.7%. Brain metastasis was present in 42.7% of patients. Most patients had previously received EGFR TKI therapy, however, only 8% and 30% received third-generation TKI as first-line therapy in the ABCP arm and  chemo-only arm, respectively. The majority of the patients were EGFR at  90%.
