Researchers are evaluating efruxifermin EFX in a phase 3, randomized, double-blind, placebo-controlled study involving adults with compensated cirrhosis caused by NASH Nonalcoholic Steatohepatitis or MASH Metabolic Dysfunction-Associated Steatohepatitis. This study aims to assess the safety and effectiveness of EFX in preventing significant clinical events such as disease progression and liver decompensation over a period of up to 5 years. Participants are randomly assigned to receive either efruxifermin 50 mg or a placebo, both given by subcutaneous injection. The study includes two cohorts one with biopsy-proven compensated cirrhosis and specific metabolic scores, and another with biopsy-proven or non-invasive diagnosis of compensated cirrhosis. The study treatment and monitoring extend up to 5 years, with evaluations at 96 weeks and long-term follow-up to track liver fibrosis, markers of liver injury, insulin sensitivity, glycemic control, body weight, and safety outcomes. During the trial, participants undergo regular assessments including laboratory tests, ECGs, ultrasounds, and vital sign monitoring. Researchers will measure changes in liver fibrosis, steatohepatitis resolution, and metabolic markers throughout the study. Safety and tolerability are closely tracked by documenting adverse events and exposure duration. The study duration allows for long-term observation of treatment effects and disease progression, with participant involvement lasting up to 5 years.

Researchers are evaluating efruxifermin EFX in adults with non-cirrhotic nonalcoholic steatohepatitis NASH or metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage 2 or 3. This Phase 3, multi-center, randomized, double-blind, placebo-controlled study aims to assess the safety and efficacy of EFX compared with placebo. The trial includes about 1,650 participants divided into two cohorts based on liver biopsy characteristics and fibrosis stage. Participants will be randomly assigned to one of three groups EFX 28 mg, EFX 50 mg, or placebo, each given as a weekly subcutaneous injection. Cohort 1 will be evaluated over 52 weeks for histologic efficacy endpoints, while Cohort 2 will have assessments over 96 weeks. After these periods, participants may continue long-term treatment and clinical follow-up for up to approximately 240 weeks total. A follow-up visit will occur about 30 days after the last dose. During the study, participants will undergo liver biopsies, blood tests, and non-invasive assessments such as FibroScan and Enhanced Liver Fibrosis ELF score to monitor liver health and fibrosis. Researchers will track liver-related clinical outcomes, including liver events and survival, as well as safety and tolerability of the treatment. Participants who stop the study drug may still continue with scheduled assessments to support long-term safety and efficacy evaluations.
