Safety and Efficacy of ALLO-501 Anti-CD19 Allogeneic CAR T Cells in Adults With Relapsed/Refractory Large B Cell or Follicular Lymphoma (ALPHA)
November 30, 2023 updated by: Allogene Therapeutics
A Single-Arm, Open-Label, Phase 1 Study Evaluating the Safety, Efficacy, and Cellular Kinetics/Pharmacodynamics of ALLO-501, an Anti-CD19 Allogeneic CAR T Cell Therapy, And ALLO-647, An Anti-CD52 Monoclonal Antibody, in Patients With Relapsed/Refractory Large B-Cell Lymphoma or Follicular Lymphoma
The purpose of the ALPHA study is to assess the safety, efficacy, cell kinetics and immunogenicity of ALLO-501 in adults with relapsed or refractory large B-cell lymphoma or follicular lymphoma after a lymphodepletion regimen comprising fludarabine, cyclophosphamide, and ALLO-647.
