Not Yet Recruiting · Early Phase 1 · Chengdu Ucello Biotechnology Co., Ltd. · registry updated 2025-12-05
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
The purpose of this clinical trial is to learn if CD19/BCMA CAR-T works to treat refractory SLE in adults. It will also learn about the safety and efficacy of the CD19/BCMA CAR-T cell product. The main questions it aims to answer are: 1. What CAR-T-related adverse events (AEs) occur within 3 months after the CAR-T cell infusion? 2. Which dose level is the optimal biological dose (OBD)? 3. What is the the changes of disease activity status, proportion of patients achieving DORIS remission, percentage of participants achieving maintenance of drug-free DORIS remission, proportion of patients achieving SRI-4 remission, percentage of participants achieving maintenance of LLDAS? Participants will: 1. Receive CD19/BCMA CAR-T cells infusion on Day 0. 2. Be hospitalized for at least 7 days post-infusion for close safety monitoring and remain within 2 hours of the treatment facility for at least 28 days. 3. Visit the clinic at Day 14, Day 28, month 3, month 6, month 9, month 12, month 18 and month 24 after CAR-T cells infusion.
