Study of ALA-101 in Patients With CD19 Positive Non-Hodgkin Lymphoma and Leukemia.

This is a Phase 1, open-label, dose-escalation and expansion study evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and preliminary efficacy of ALA-101, an allogeneic, off-the-shelf CD19-directed CAR-iNKT cell therapy, in patients with CD19-positive non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), and hairy cell leukemia (HCL).

The dose-escalation phase will assess safety and determine the maximum tolerated dose (MTD). The dose-expansion/backfill phase will further evaluate safety and preliminary efficacy and establish the recommended Phase 2 dose (RP2D).

Study participation includes screening, lymphodepletion, treatment, and follow-up periods. An end-of-study visit will occur at Month 24, after which participants will enter a long-term follow-up study.
