Exploratory Study of YTS109 Cell Therapy for Adults Aged 18 to 65 With Relapsed or Refractory Autoimmune Diseases Including SLE, Sjogrens Syndrome, and Rheumatoid Arthritis

What this Trial Is About

Researchers are evaluating the safety and potential effectiveness of YTS109 cells in adults aged 18 to 65 who have relapsed or refractory autoimmune diseases, including systemic lupus erythematosus, systemic sclerosis, and several others. This exploratory clinical trial aims to better understand how well YTS109 cells work and their safety when used with a lymphodepletion regimen. The study is conducted as a single-arm, open-label trial at a single center. Participants will receive one infusion of YTS109 cells at a dose of 1.5 million cells per kilogram of body weight. The study focuses on monitoring adverse events and assessing efficacy over various time points. The treatment is designed to target and reduce B cells to help manage autoimmune responses. The trial plans to enroll approximately 6 to 12 patients. During the study, participants will be closely monitored for safety and treatment effects at intervals including 2, 4, 8, 12, 24, and up to 52 weeks after treatment. Researchers will conduct blood tests to measure the levels of YTS109 cells, biomarker changes, and immune system responses. The primary outcomes are the type, severity, and frequency of any adverse effects, along with efficacy evaluations. The total observation period extends up to one year to thoroughly assess safety and response to treatment.
