New treatment option for Systemic Lupus Erythematosus (SLE)
Official title Exploratory Clinical Study on YTS109 Cell Therapy for Autoimmune Diseases
ClinicalTrials.gov ID: NCT07236801
What this study is testing
What is YTS109 cell?
YTS109 cell is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for systemic lupus erythematosus (sle).
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study evaluates the safety and efficacy of YTS109 cells in adults with relapsed/refractory autoimmune diseases, such as Systemic Lupus Erythematosus (SLE), including LN and SLE-ITP, Sjogren's Syndrome, etc. Aproximately 18 patients aged 18-65 will receive a single infusion of YTS109 cells.
