MT2025-20: A Phase II, multi-part, five-year, randomized, open-label, assessor-blinded, active-controlled, multicenter study to evaluate the efficacy and safety of rapcabtagene autoleucel versus rituximab treatment in participants with severe refractory diffuse cutaneous systemic sclerosis

The goal of this study is to find out if the experimental drug rapcabtagene autoleucel (herein referred to as YTB323), an investigational new therapy, is safe and effective (can help) for people who have severe refractory diffuse cutaneous systemic sclerosis (dcSSc). YTB323 is a chimeric antigen receptor T cell (CAR-T cell) therapy, which is a type of gene therapy or immunotherapy. CAR-T involves collecting and using a patient’s own immune cells, specifically their T cells, to treat their condition.
