Researchers are evaluating the efficacy and safety of two different dose regimens of pegozafermin compared to a placebo in adults with metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage F2 or F3. This Phase 3 study aims to better understand how pegozafermin may impact liver fibrosis and steatohepatitis in this population. Participants will receive subcutaneous injections of either one of two pegozafermin regimens or a matched placebo. These treatments are given in parallel groups, and participants are randomly assigned to one of the study groups. The study compares the effects of pegozafermin on liver fibrosis and steatohepatitis over a treatment period that includes evaluations up to 52 weeks and monitoring for disease progression up to 5 years. During the study, participants will be monitored through biopsies and blood tests to assess liver fibrosis improvement, resolution of steatohepatitis, changes in liver enzyme levels, and enhanced liver fibrosis scores. Safety and disease progression are also tracked throughout the study period. The total participation duration includes treatment and long-term observation to evaluate outcomes and any potential changes in liver health.
