RY_SW01

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.

RY_SW01 Cell Injection's preclinical research results have shown that the injection significantly improved urine biochemical indicators and tissue damage in two lupus nephritis animal models after MSC administration, with no occurrence of rejection and excellent safety. The mechanism of action of RY_SW01 Cell Injection is relatively clear, demonstrating favorable therapeutic effects in preclinical animal models. Compared to existing conventional therapies, it has the advantages of "convenient treatment and sustained efficacy." It may help reduce the variety and quantity of drugs administered to patients and the various side effects associated with drug treatment. In some cases, it may even lead to the discontinuation of immunosuppressive drugs, reducing mortality and disability rates while improving the quality of life for patients. Its unique advantages have the potential to fundamentally change the current clinical treatment landscape and offer promising prospects for clinical application.
