Официальное название

Chiglitazar in Combination With Anti-Inflammatory and Hepatoprotective Therapy for the Treatment in MASH Associated With T2DM: a Prospective, Multicentre, Randomised, Double-blind, Placebo-controlled Study

Обзор

This trial aims to evaluate the efficacy and safety of chiglitazar as a combination therapy for patients with MASH and T2DM.

Подробное описание

Metabolic dysfunction-associated steatohepatitis (MASH), used to be called non-alcoholic steatohepatitis (NASH), is a manifestation of the metabolic syndrome in the liver, particularly when co-occurring with type 2 diabetes (T2DM), presents a significant therapeutic challenge due to a higher risk of fibrosis progression and adverse outcomes. While new treatments for MASH are emerging, their efficacy in the T2DM subpopulation remains an area of unmet need. Chiglitazar is a novel peroxisome proliferator-activated receptor (PPAR) pan-agonist that regulates key pathways in lipid metabolism, glucose homeostasis, and inflammation. This trial aims to evaluate the efficacy and safety of chiglitazar as a combination therapy for patients with MASH and T2DM.

This is a prospective, multicentre, randomised, double-blind, placebo-controlled study. The trial will enroll 300 adult patients aged 18-75 years with biopsy-confirmed MASH and fibrosis stage F1b or higher. Participants will be randomised (1:1) to receive either chiglitazar 48 mg daily or a matching placebo. All participants will also receive background therapy consisting of vitamin E (100 mg three times a day) and polyene phosphatidylcholine (456 mg three times a day). The treatment duration is 72 weeks. The primary efficacy endpoint is the resolution of steatohepatitis with no worsening of liver fibrosis. Key secondary endpoints include improvement in liver fibrosis by at least one stage and changes in metabolic and liver safety biomarkers.
