Phase 3 Study of Efimosfermin Alfa for Adults With Biopsy-Confirmed Moderate to Severe Metabolic Dysfunction-Associated Steatohepatitis MASH and Liver Fibrosis

What this Trial Is About

Researchers are evaluating efimosfermin alfa in adults with biopsy-confirmed metabolic dysfunction-associated steatohepatitis MASH and stage F2 or F3 liver fibrosis. The study aims to assess the safety and effectiveness of efimosfermin alfa compared to a placebo in resolving steatohepatitis and improving liver-related clinical outcomes. This Phase 3 trial is randomized, double-blind, and placebo-controlled, focusing on participants with specific liver conditions and metabolic syndrome components. Participants are assigned to one of three groups two groups receive different dose levels of efimosfermin alfa, while the third group receives a placebo. Treatments are given under controlled conditions, and the study follows a parallel design. The trial monitors participants at set intervals over a course of 52 weeks, with some outcomes tracked up to 48 months to evaluate long-term effects on liver fibrosis and steatohepatitis. During the study, participants undergo liver biopsies to confirm diagnosis and assess changes. Researchers evaluate improvements in fibrosis stage, steatohepatitis resolution, and various liver function measurements using imaging and blood tests. Safety is monitored by tracking adverse events and laboratory abnormalities. Quality of life and other health indicators are also assessed throughout the study, which lasts several years to capture both short- and long-term outcomes.
