The Emergence of Triplet Therapies in ccRCC in the Frontline Setting

  • Resumen

  • Drs. Pedro Barata and Naomi Haas discuss the emergence of clinical trials investigating triplet combinations in advanced renal cell carcinoma, factors that influence treatment decisions, strategies to personalize therapies in the frontline setting, including response-adaptive treatment strategies, and the use of biomarkers such as gene expression analysis to guide initial therapy. TRANSCRIPT Dr. Pedro Barata: Hello, I'm Dr. Pedro Barata. I'm your guest host of the ASCO Daily News Podcast today. I'm an associate professor of medicine and also a GU medical oncologist at University Hospital Seidman Cancer Center, Case Western University in Cleveland, Ohio. I'm also an associate editor for the ASCO Educational Book. Today I'm really delighted to welcome Dr. Naomi Haas, the director of the Prostate and Kidney Cancer Program at the Abramson Cancer Center and professor of medicine at the University of Pennsylvania.  Welcome, Dr. Haas. Dr. Naomi Haas: Thank you, Dr. Barata. It's a pleasure to be interviewed. Dr. Pedro Barata: Thank you. As you know, we've seen significant strides in the frontline treatment for patients with advanced clear cell renal cell carcinoma (RCC), and there are multiple doublet regimens that are now the standard of care for those patients. The goal for us to chat today is to discuss the emergence of clinical trials that are really investigating triple combinations and the factors that influence treatment decisions around triplet combinations for patients with advanced renal cell carcinoma. I want to congratulate you for the great work that you did in a recently published article in the 2023 ASCO Educational Book. So thank you for your contributions. And just before we get started, I just want to highlight that our full disclosures are available in the transcript of this episode. So, Dr. Haas, again, it’s great to have you. Thank you for taking the time. Let me get started. So, we know that there are multiple standard of care doublet regimens, all of them immunotherapy-based combos, and they usually include 1 checkpoint inhibitor or 2, such as ipilimumab plus nivolumab or a combination of an immune checkpoint inhibitor with a VEGF TKI. And we have a number of examples like that. Can you tell us about the trials that have emerged exploring triplet therapies in the first-line setting for patients with advanced RCC? Dr. Naomi Haas: Sure, and I'm going to focus just on triplet therapies that are just about ready to go. But as you know, Pedro, there are probably many different combinations that we'll see in the future. Some of the combinations that have already been conducted as clinical trials include combinations of VEGF receptor tyrosine kinase inhibitors along with immune checkpoint inhibitors. I'll highlight one which was batiraxcept plus cabozantinib and nivolumab, and it's a combination of VEGF inhibitor, immune checkpoint inhibitor, and also an AXL inhibitor. So, most of these capitalize on other vulnerabilities with renal cell carcinoma.  So, as you said, they build on the tyrosine kinase inhibitor pathway or on the immune checkpoint inhibitor pathway. Some of them are combining drugs such as CDK inhibitors. There was axitinib plus nivolumab plus palbociclib trial that is getting ready to launch. Others are combining the use of belzutifan, which is a HIF inhibitor in combination with VEGF inhibitor and immune checkpoint inhibitor. There are a couple of those that are ongoing, one of them looking at combinations with lenvatinib. And I think there are also trials getting ready to launch that are using it in combination with cabozantinib and nivolumab.  Additionally, another very interesting direction is trying to affect the gut microbiome. And there was a clinical trial presented by Dr. Monty Pal at the gut microbiome session at ASCO, which combined CBM-588, which is a probiotic, in combination with cabozantinib and nivolumab. And that showed an improvement in progression-free survival compared to the combination of cabozantinib and nivolumab alone. And previously there was work published using CBM-588 in combination with ipilimumab and nivolumab. So that's an area of high interest to patients. But most of these combinations capitalize on either vulnerabilities, signs of resistance in pathways or in adding other pathways that have previously been unaddressed in renal cell carcinoma, and are combined with pathways that we know are effective. Dr. Pedro Barata: Wow, that's a fantastic overview of some of the approaches being considered in the frontline, so thank you for that. And actually to your point, some of them we've seen some data, others more later stages of development. So with that in mind, we also know that we have on one side of the story we have how much of these combos of triplets can actually be effective and help patients. From the other perspective is about tolerability, treatment options, and patient health. They're both very important considerations.  Can you tell...
