Summary

AID is a phase I multi-cohort study to assess the safety and tolerability of zamtocabtagene autoleucel (zamto-cel) in patients with refractory autoimmune diseases (SLE-Non renal, SLE-LN, SSc/dcSSc) after receiving standard therapy.

Detailed description

This is a Phase 1, multicohort, dose-finding study evaluating autologous T cells engineered to target dual CD19 and CD20 antigens in subjects with refractory autoimmune diseases following standard therapy. The investigational product, Zamto-cel, is a chimeric antigen receptor T-cell (CAR-T) therapy genetically engineered to enable subjects' T cells to express CARs on their surfaces. Eligible subjects will undergo leukapheresis for the collection of cells required for manufacturing. Prior to infusion of the fresh CAR-T product, subjects will receive a lymphodepleting regimen consisting of cyclophosphamide and fludarabine. The CAR-T cell infusion will be administered intravenously at a dose of 2.5 x 10\^6 or 1.0 x 10\^6 CAR+ cells/kg body weight, based on the dose level assigned to the cohort. The study will initially enroll 3 subjects per cohort in a staggered manner to evaluate safety. Upon confirmation of safety, the study will proceed to cohort-specific recommended Phase 2 dose (RP2D) and dose expansion phases. Subjects will be monitored for up to 1 year to assess safety, preliminary efficacy, and health-related quality of life (HRQoL). Additional long-term follow-up will be conducted under a separate long-term follow-up protocol.
