SSc-Systemic Sclerosis

This is a single-arm, open-label, phase I clinical study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD06-05, a universal CD19/BCMA dual-targeting chimeric antigen receptor T-cell (CAR-T), in pediatric and adolescent patients with refractory autoimmune diseases, including systemic lupus erythematosus/lupus nephritis (SLE/LN), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM), multidrug-resistant nephrotic syndrome (MDR-NS), and refractory IgA nephropathy (IgAN). Approximately 30 eligible patients will be enrolled and receive a single intravenous infusion of RD06-05 at an initial dose of 6×10⁶ CAR+ T cells/kg, with a potential dose escalation to 10×10⁶ CAR+ T cells/kg following review by a Safety Review Committee (SRC).

This study is an open-label, multiple ascending dose investigator-initiated trial (IIT) designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of CC312 in adult patients with relapsed or refractory autoimmune diseases.

CAR T-cell Therapy Targeting CD19 and BCMA(QT-019C) in Patients With Relapse/Refractory Autoimmune Diseases

This study is a single arm, open label, exploratory dose escalation clinical study to evaluate the safety, efficacy, and cellular metabolic dynamics of ct1195e cells in patients with SSc. The study was divided into dose escalation phase and dose expansion phase.
