Clinical Deep Dive: Unlocking the Treatment Potential of Rezdiffra
This educational discussion dives into Rezdiffra, the first and only FDA-approved therapy for non-cirrhotic metabolic-associated steatohepatitis (MASH) with moderate to advanced fibrosis. The talk provides a clinical deep dive into the progression of MASH and fibrosis, highlighting the risks of untreated disease and the importance of early intervention. A key focus is the thyroid hormone receptor beta mechanism, explaining how Rezdiffra directly targets liver-specific pathways to reduce hepatic fat accumulation and fibrosis. Additionally, the discussion covers the rigorous FDA approval process and dual efficacy endpoints, detailing how Rezdiffra achieved significant fibrosis improvement and steatohepatitis resolution in the MAESTRO-NASH trial. The session also provides practical insights into patient access, prescribing considerations, and managing common side effects. With over 2,000 patients studied, Rezdiffra has demonstrated a strong safety profile and offers a once-daily oral treatment option that represents a major advancement in MASH management. This discussion is essential for gastroenterologists, hepatologists, and endocrinologists managing patients with MASH, as well as primary care providers and cardiologists who play a role in identifying at-risk individuals. If you are a healthcare professional looking to stay updated on the latest MASH research and treatment strategies, this session provides the insights you need.
