A Multicenter Phase I/II Clinical Trial to Evaluate the Safety, Tolerability, and Efficacy of RY_SW01 Cell Injection Therapy in Systemic Sclerosis
Systemic sclerosis (SSc) tends to progress to involve multiple vital organs within 5 years of diagnosis, significantly impacting patient prognosis and survival. Clinical indications suggest that early intervention is more favorable for long-term outcomes in patients. Although guidelines recommend various drugs for symptomatic treatment, there is currently no standard therapy or effective medication to slow the progression of the disease. Therefore, for patients with diffuse SSc, as defined by a skin score of 10≤mRSS≤30 points, who have been treated with at least two therapies, including steroids, immunosuppressive agents, biologics, etc., within 5 years of diagnosis, the applicant intends to develop a drug that can both modulate the immune system and counteract fibrosis. The goal is to provide long-term benefits to patients through early intervention.
