Clinical Study of ET190L1 ARTEMIS™ in Relapsed, Refractory B Cell Lymphoma

Phase 1, Open-label, Single-arm, Dose-escalation Clinical Study Evaluating the Safety and Efficacy of ET190L1 ARTEMIS™ (Anti-CD19-ARTEMIS™) in Relapsed, Refractory B Cell Lymphoma

This study is to determine the safety, including potential dose limiting toxicities, of ET190L1 ARTEMIS™ T cells and the duration of in vivo survival of ET190L1 ARTEMIS™ T cells in patients with relasped/refractory B-cell lymphoma. For patients with detectable disease, the study will also measure anti-tumor responses after ET190L1 ARTEMIS™ cell infusions.

ET190L ARTEMIS™ is a novel chimeric T-cell therapy platform that in preclinical studies, functionally matches the efficacy of CAR T cells, but dramatically reduces the release of cytokines upon killing of target-positive tumors.
