Details and patient eligibility


This is a Phase Ib/II study to evaluate the safety and efficacy of autologous T cells engineered with a chimeric antigen receptor (CAR) targeting CD19 in adult patients with relapsed or refractory B cell acute lymphoblastic leukemia (ALL).

Full description

This Phase Ib/II, open-label, multi-center, single arm study is designed to evaluate the safety and efficacy of AUTO1 in adult patients with B-cell ALL by determining the overall response rate (ORR). Adult patients with relapsed or refractory ALL will be enrolled in both phases of the study. Consented patients will go through the following five sequential stages: screening, leukapheresis, pre-conditioning, treatment, and follow-up. All patients will receive a total target dose of 410E+6 of CAR T cells as a split dose on Day 1 and on Day 10 (±2 days).
