CHT105 for the Treatment of Refractory Lupus Nephritis

Systemic lupus erythematosus (SLE) is the most common systemic autoimmune disease in China. The kidneys are the organ most frequently affected in SLE and a major cause of mortality among SLE patients. Currently, cell-based therapy has emerged as an innovative treatment approach for SLE. CHT105 injection is an allogeneic chimeric antigen receptor T (CAR-T) cell product derived from healthy donors' T cells, which are transduced with a lentiviral vector encoding an anti-CD19/CD70 CAR. This engineered T-cell product effectively recognizes and eliminates immune cells expressing CD19 and/or CD70 antigens-including autoreactive T and B cells-and holds promise as a novel therapeutic option for patients with refractory lupus nephritis (LN). This study is a clinical trial evaluating the safety and preliminary efficacy of CHT105 injection-a CD19/CD70-targeting allogeneic CAR-T cell product-in adult patients with relapsed or refractory LN. Eligible participants will first undergo lymphodepleting preconditioning. Following confirmation of eligibility per standard infusion criteria, participants will receive a single intravenous infusion of CHT105 on Day 0 (D0). After CHT105 infusion, participants will undergo a 52-week short-term follow-up and up to a 15-year long-term follow-up.
