| 1 | Safety & Efficacy of ALLO-501A Anti-CD19 Allogeneic CAR T Cells in Adults With R/R LBCL This is a single-arm, open-label, multicenter Phase 1/2 study evaluating the safety, efficacy, cellular kinetics, and immunogenicity of ALLO-501A in adult subjects with R/R LBCL.
Once eligibility has been established the treatment phase will occur over the span of 6 days. During lymphodepletion, patients will receive fludarabine, cyclophosphamide, and ALLO-647. ALLO-647 is an experimental antibody. One dose of ALLO-501A will be administered after the lymphodepletion period. ALLO-501A is made in the laboratory by modifying white blood cells, from a healthy person (donor) to help it recognize and fight LBCL.
Patients will be monitored for up to 5 years from the initial ALLO-501A infusion. After the 5 years patients will have the option to be followed for 10 additional years in a separate noninterventional, long-term, safety-monitoring study.

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Phase 2 Primary Endpoints: Efficacy, ORR, defined as assessment of CR or PR, assessed using the Lugano classification criteria 2014; Cheson et al, 2014) by IRC.
Secondary endpoints 16
- Secondary Endpoints (Phase 1 and 2): Efficacy ALLO-501A: DOR is defined only for subjects who experience an objective response and is the time from the first objective response to disease progression per (Cheson et al, 2014) and per IRC (Phase 2 only) and per investigator assessment) or death, whichever comes first.
- Secondary Endpoints (Phase 1 and 2): Efficacy ALLO-501A: ORR per investigator assessment
