SOUTH SAN FRANCISCO, Calif., Aug. 04, 2021 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) therapies for cancer, today provided a corporate update and reported second quarter 2021 financial results for the quarter ended June 30, 2021.

“We have made exceptional progress across our broad pipeline of AlloCAR T candidates, bringing our goal of revolutionizing cell therapy for patients with blood cancers and solid tumors closer to reality,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “Our foundational and ongoing work has the potential to drive us toward an industry first - our planned pivotal trial for ALLO-501A in relapsed/refractory non-Hodgkin lymphoma which we expect to initiate at the end of this year. This month, we are also marking an exciting milestone with the planned inauguration of our state-of-the-art manufacturing facility, Cell Forge 1. This facility is intended to allow us to control manufacturing of ALLO-501A and future therapies and prepare us for potential commercialization.”

Pipeline Highlights

Anti-CD19 Program: ALPHA and ALPHA2 Trials

• Updated data from the ongoing Phase 1 ALPHA (ALLO-501) and ALPHA2 (ALLO-501A) trials in relapsed/refractory non-Hodgkin lymphoma (NHL) presented at the Company’s CD19 Forum in May and Annual Meeting of the American Society of Clinical Oncology (ASCO) in June.
• Data from the ALPHA trial supports the ability of a single administration of ALLO-501 to generate deep and durable responses at a rate that is similar to approved autologous CAR T therapies. In the trial, 98% of patients received ALLO-501 with an average time from enrollment to the start of therapy of five days.
  • Durable complete responses (CR) were observed with the longest ongoing CR at 15 months in both large B cell lymphoma (LBCL) and follicular lymphoma.
  • Overall response rate (ORR) of 75% and CR rate of 50% across histologies in CAR T naïve patients, and on par with data from pivotal trials of autologous CAR T therapies.
  • Six-month CR rate of 36% in CAR T naïve patients with LBCL.
• Interim Phase 1 ALPHA2 data demonstrated a comparable efficacy and safety profile for ALLO-501A relative to ALLO-501.
  • Consolidation dosing was well tolerated and showed early promise with four patients converting from partial response (PR) to CR following second dose of ALLO-501 or ALLO-501A.
  • 75% ORR and 63% CR among patients (n=8) treated in the consolidation cohorts across ALPHA studies.
• ALLO-501 and ALLO-501A demonstrated a manageable safety profile with no dose limiting toxicities or graft-vs-host disease, limited immune effector cell-associated neurotoxicity syndrome (ICANS) and cytokine release syndrome (CRS) observed.
• Next readout from this program is expected in late 2021.
• The Company plans to collect additional data from the consolidation arms of the ALPHA and ALPHA2 studies, finalize a dose and schedule of ALLO-501A and lymphodepletion for a pivotal Phase 2 trial, and discuss the Phase 2 trial design with regulatory authorities.
• Pending regulatory feedback, the Company plans to move to the Phase 2 Pivotal ALPHA2 trial at the end of 2021.

Anti-BCMA AlloCAR T Program
The Company continues to advance its portfolio of allogeneic therapies targeting the B cell maturation antigen (BCMA) for patients with multiple myeloma (MM).

• ALLO-715 UNIVERSAL Trial
  • The UNIVERSAL trial, investigating ALLO-715 as a monotherapy and in combination with nirogacestat, SpringWorks Therapeutics’ investigational gamma secretase inhibitor, continues to enroll patients with relapsed/refractory MM.
  • Updated data from the monotherapy arm of the study are anticipated in Q4 2021.
  • In April, ALLO-715 was granted Regenerative Medicine Advanced Therapy (RMAT) designation by the U.S. Food and Drug Administration (FDA).

• ALLO-605 TurboCAR™ IGNITE Trial
  • The Phase 1 dose escalation portion of the IGNITE trial evaluating ALLO-605, the first anti-BCMA TurboCAR T cell therapy, began dosing patients.
  • In June, the FDA granted ALLO-605 Fast Track designation based on the potential of ALLO-605 to address the unmet need for patients who have failed other standard MM therapies.
    

Solid Tumor AlloCAR T Program

• ALLO-316 (anti-CD70) TRAVERSE Trial
  The Phase 1 TRAVERSE trial of ALLO-316, Allogene’s first CAR T candidate for solid tumors, in patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC) continues to progress with initial data anticipated in 2022. The trial is examining safety, tolerability, anti-tumor efficacy, pharmacokinetics and pharmacodynamics of ALLO-316.

Corporate Highlights

• Manufacturing Updates
  • The Company plans to unveil its state-of-the-art cGMP cell manufacturing facility, Cell Forge 1, in Newark, California in preparation for a pivotal trial of ALLO-501A and future commercialization. Company is on track to begin cGMP production in this facility in the second half of 2021.

• Allogene Overland Biopharm
  • Allogene Overland Biopharm, a joint venture created with Overland Pharmaceuticals, appointed Shuyuan Yao, Ph.D., as Chief Executive Officer. Dr. Yao brings 15 years of scientific and management experience in advanced cell and gene therapy development, manufacturing and commercialization, and will lead Allogene Overland in its mission to bring certain AlloCAR T therapies to patients in China and other Asian Pacific markets.
