S5 - E11.2 - Defining Therapeutic Futility For Rezdiffra And Discussing Advances In MASLD Translational Medicine

Send us Fan MailMichael Charlton and the Surfers discuss two issues: defining therapeutic futility for Rezdiffra and describing some advances in MASLD translational medicine. The conversation starts by continuing the topic of therapeutic futility. Louise Campbell asks Michael how he plans to determine therapeutic futility with Rezdiffra in terms of side effects or efficacy. Michael indicates that he will continue patients on Rezdiffra as long as their disease does not progress. While he would prefer a more robust approach, he describes the scale of challenge in defining futility for a drug where FibroScan and transaminase levels did not provide strong prediction.Roger Green asks what percentage of patients are taking concomitant GLP-1 therapy. This leads to a brief sideline discussion on levels of therapeutic adherence.Roger asks Michael what he find exciting in translational medicine these days. Michael cites the LiverRisk score, a developing test he describes as "substantially superior" to other biomarkers. His group is currently working with NHANES data to see whether this is predictive for patients who had transient elastography and met MASH criteria. He particularly wants to determine whether this is a dynamic test. Michael goes on to discuss the work his group is doing on the microbiome, where he and others are finding potentially valuable insights. The challenge continues to be how to translate these insights into clinically meaningful interventions.
