Dr. Diwakar Davar and Dr. Jason Luke, both of the University of Pittsburgh’s Hillman Cancer Center, share the latest news on immunotherapy trials KEYNOTE-A10, LIBRETTO-001, and other key IO studies across tumor types featured at the 2022 ASCO Annual Meeting.  Transcript Dr. Diwakar Davar: Hello, and welcome to the ASCO Daily News Podcast. I am Dr. Diwakar Davar, and I'm an assistant professor of Medical Oncology in phase 1 therapeutics, at the University of Pittsburgh's Hillman Cancer Center, and the guest host of today's podcast. I'm delighted to welcome Dr. Jason Luke to this podcast. He's the director of the Cancer Immunotherapeutic Center at the Hillman Cancer Center, University of Pittsburgh, and a great colleague and friend.  Today we'll be discussing some key posters that highlight some advances in immunotherapy that will be featured and the 2022 ASCO Annual Meeting. You will find our collective disclosures in the show notes and the disclosures of all guests on the podcast are available on our transcripts at asco.org/podcasts.  So, Jason, thank you for coming on the podcast today.  Dr. Jason Luke: Well, thanks very much for the invitation. I always love doing these podcasts for ASCO, and never love anything more than hanging out with my friend Diwakar Davar.  Dr. Diwakar Davar: Well, thank you! Below are the abstracts we've selected. We will start with Abstract 2504. This is a phase 1 trial of the TIM-3 inhibitor cobolimab monotherapy, singly and in combination with the PD-1 inhibitors nivolumab or dostarlimab. Phase 1 data from the AMBER trial with the presenting author being Dr. Gerald Falchook. And this is a trial that initially started several years ago. And I know Jason, that you were involved with the inception of this agent, that TIM-3 inhibitor. So, walk us through, TIM-3. It's a third-generation checkpoint, we now have TIGIT LAG coming into the landscape. Definitely a first indication for LAG-3 melanoma with a positive trial, RELATIVITY 047. So, where are we with TIM-3? Why should we be excited about TIM in general, and this data in particular?  Dr. Jason Luke: It is quite exciting, especially building off the recent data that we saw for relatlimab or LAG-3 because it's becoming clearer that a number of these other immune checkpoints that we have been talking about for many years, actually really can be effective when used in the right setting.  So, this drug, this anti-TIM-3 antibody cobolimab monotherapy, as you mentioned, started out in a phase 1 clinical trial dating all the way back to I think about 2015. And that was at the time in immuno-oncology when everybody was so excited, [and] they thought everything was going to work immediately.  Subsequent to that, obviously, we've had some hurdles that we've had to come over. But we're coming back to some of these agents now, which are looking very exciting. So, just in the same way we think about blocking PD-1 or now blocking LAG-3 to reinvigorate T cells in the tumor microenvironment, there's a good chance and a high probability based on preclinical data that blocking TIM-3 could be just as effective as blocking LAG-3, so to say.  Now, one thing that I note in this abstract is really the safety finding and early PK analysis. And so, this is the important work we do early on to understand the drug. It's important to be aware that in a study like this, it's very hard to seek efficacy signals.  So, when you see this poster, really, you probably shouldn't be thinking, ‘Oh, this is a frontline phase 3 trial,’ but rather that the efficacy is going to be a secondary consideration. Rather, what's quite important is looking at the properties of the drug and looking at the safety signals around that. And what we can see here is that TIM-3 appears to be quite safe when blocking it in conjunction with anti-PD-1 across several different tumor types. And that really sets the stage then to think about moving this into earlier lines of therapy across many
