Phase 1 Open-Label Dose-Escalation and Expansion Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of ALA-101

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.

• Adequate Hepatic and Renal Function
• Adequate Bone Marrow Function
• Adequate ECG Vales
• Agree to use appropriate contraception to avoid becoming pregnant for up to 12 months post treatment and agree not to donate sperm or ova for 12 months post treatment

Exclusion Criteria:
