Summary

This multi-center, open-label, Phase 1/2 study aims to evaluate the safety, tolerability, and preliminary efficacy of C-CAR168, an autologous anti-CD20/BCMA CAR-T therapy, in patients with autoimmune diseases refractory to standard treatments. The study includes both dose escalation and dose expansion phases, with participants grouped into condition-specific cohorts. The purpose of this study is to: 1. Test the safety and ability for subjects with autoimmune refractory to standard treatment to tolerate the C-CAR168. 2. Determine the recommended Phase 2 dose of C-CAR168 in subjects with autoimmune disease refractory to standard treatment. Participants will be asked to: * Undergo screening to determine eligibility based on entry criteria. * Taper steroid use before leukapheresis. * Undergo leukapheresis for the manufacturing of C-CAR168. * Temporarily discontinue immunosuppressive therapy at least 7 days prior to leukapheresis. * Receive bridging therapy (steroids) if necessary to maintain disease stability during C-CAR168 manufacturing. * Undergo lymphodepletion therapy with fludarabine and cyclophosphamide. * Receive a single intravenous infusion of C-CAR168 at the assigned dose level on Day 0. * Attend regular safety and efficacy assessments for up to 24 months post-infusion. * Undergo dose-limiting toxicity evaluation during the first 28 days post-infusion (for those in the dose escalation phase). * Follow withdrawal procedures if necessary, including a discharge visit within 14 days if their condition deteriorates, unacceptable toxicity occurs, they no longer meet criteria, or they choose to withdraw.
