Official title
Phase 1/2 Study of Anti-CD33 Chimeric Antigen Receptor-Expressing T Cells (CD33CART) in Children and Young Adults With Relapsed/Refractory Acute Myeloid Leukemia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase 1/2 trial aims to determine the safety and feasibility of antiCD33 chimeric antigen receptor (CAR) expressing T cells (CD33CART) in children and adolescents/young adults (AYAs) with relapsed/refractory acute myeloid leukemia (AML). The trial will be done in two phases: Phase 1 will determine the maximum tolerated dose of CD33CART cells using a 3+3 trial design, with dose-escalation for autologous products separated from dose-escalation for an allogeneic arm. Phase 2 is an expansion phase designed to evaluate the rate of response to CD33CART.
