Outcomes
Primary Outcome Measures
Phase 1: Proportion of subjects experiencing Dose Limiting Toxicities at increasing doses of ALLO-605 that will determine MTD/MAD and select the recommended Phase 2 dose (RP2D) of ALLO-605.
Dose limiting toxicity is defined as protocol-defined ALLO-605 related adverse events with onset within 28 days following infusion
Phase 1: Proportion of patients experiencing Dose Limiting Toxicities with ALLO-647 [administered in combination with fludarabine/cyclophosphamide administered prior to ALLO-605]
Dose-limiting toxicity is defined as protocol-defined ALLO-647-related adverse events with onset within 30 days following 1st infusion
Phase 2: To assess clinical efficacy of ALLO-605 as measured by overall response rate (ORR)
