(Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer, today announced the presentation of data from a comprehensive safety review of patients treated in the Phase 1 ALPHA/ALPHA2 trials with ALLO-501/501A at the 65th Annual Meeting of the American Society of Hematology (ASH) in San Diego, CA. The safety review, which encompasses all 87 Phase 1 patients treated in both relapsed/refractory (r/r) Large B Cell Lymphoma (LBCL) and follicular lymphoma (FL), demonstrates that investigational ALLO-647 added to standard lymphodepletion can safely provide a window for the expansion and persistence of AlloCAR T cells, and has the potential to induce deep and durable remissions in relapsed and treatment-refractory cancers. \"We believe in the immense potential of off-the-shelf CAR T products to not only address the limitations of current autologous CAR T cell therapy, but to also provide greater access to patients in need,” said Zachary Roberts, M.D., Ph.D., Executive Vice President of Research & Development and Chief Medical Officer of Allogene. “We fully understand the importance of lymphodepletion to achieving optimal outcomes, and ALLO-647 is just the first generation of our innovative approaches to enhancing lymphodepletion to promote expansion of CAR T cells.” The inclusion of our ALLO-647 candidate in the lymphodepletion regimen is designed to selectively prevent host rejection of allogeneic CAR T cell products. As previously presented in the Phase 1 ALPHA/ALPHA2 studies1, CAR T cell-naive patients with r/r LBCL were able to obtain a durable response, including a complete remission rate of 42% and a median duration of response of 23.1 months. In the studies, lymphodepletion consisted of three daily doses of fludarabine 30 mg/m2 and cyclophosphamide 300-500 mg/m2 (FC) and 39, 60, or ...
