SOUTH SAN FRANCISCO, Calif., Aug. 09, 2022 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer, today provided a corporate update and reported financial results for the quarter ended June 30, 2022.
“We feel confident that we could soon initiate the industry’s first Phase 2 pivotal trial for an allogeneic CAR T product, thereby paving the road not just for ALLO-501A, but our entire portfolio,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “As the use of autologous CAR T therapy increases, we are seeing a greater need for an off-the-shelf, allogeneic CAR T option. We are keenly aware of the devastating consequences patients face when only a minority are able to access the curative potential of CAR T therapy. Clinicians have been forced into the unfathomable position of needing to choose which of their patients will receive this potentially life-saving therapy. As patients face access bottlenecks, we are determined to transform CAR T therapy from a complex individualized procedure to an off-the-shelf, on demand pharmaceutical product.”
In the coming weeks, the Company expects to receive clearance from the U.S. Food and Drug Administration (FDA) to initiate a potential Phase 2 pivotal clinical trial for ALLO-501A in relapsed/refractory (r/r) large B cell lymphoma (LBCL). This includes meeting Chemistry Manufacturing and Controls (CMC) requirements to use ALLO-501A from its manufacturing facility, Cell Forge 1.
In June, the FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to ALLO-501A in r/r LBCL. RMAT designation was based on data demonstrating the potential of ALLO-501A to address the unmet need for patients who have failed other therapies. Previously presented data support the potential of ALLO-501A to provide a safe and durable alternative to approved autologous CAR T therapies in CAR T naïve patients, including manageable safety with no dose limiting toxicities (DLTs) or graft-vs-host disease (GvHD) and minimal Grade 3 Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), or Grade 3 cytokine release syndrome (CRS). In the Phase 1 ALPHA2 study, nearly all enrolled patients were able to receive therapy with the median time from enrollment to initiation of treatment of two days.
Allogene anticipates providing an update on the Phase 1 portion of the ALPHA and ALPHA2 trials toward the end of 2022. This update will include a few additional patients enrolled in ALPHA2 and will focus on longer-term follow up of patients previously treated in the ALPHA and ALPHA2 trials.
The EXPAND trial is expected to begin in 2022 and is planned to support registration of the lymphodepleting agent ALLO-647. This trial is intended to demonstrate the contribution of ALLO-647 to the lymphodepletion regimen.
Allogene plans to explore its pivotal study approach and timing for its BCMA program by year end. In parallel, the Company intends to work within the framework afforded by its RMAT designation for ALLO-715 to facilitate FDA interactions and determine the best course forward.
Enrollment continues in the Phase 1 UNIVERSAL trial on ALLO-715 in r/r multiple myeloma (MM). Toward the end of 2022, Allogene intends to provide a clinical update that will focus on the longer-term follow up of patients in UNIVERSAL treated with a single dose of ALLO-715. Allogene has made the decision not to advance ALLO-715 in combination with nirogacestat from SpringWorks Therapeutics into dose expansion cohorts. There was no clear indication that the combination would meaningfully improve the benefit-risk profile of ALLO-715 as a monotherapy. Allogene’s Clinical Trial Collaboration Agreement with SpringWorks is expected to remain in effect until the data from the combination study are fully analyzed.
The IGNITE trial on TurboCAR™ candidate ALLO-605 continues to enroll patients in the dose escalation portion of this Phase 1 study.
Solid Tumor Programs
ALLO-316, which targets CD70, is the Company’s first AlloCAR T candidate for solid tumors. The ongoing Phase 1 TRAVERSE trial is designed to evaluate the safety, tolerability, anti-tumor efficacy, pharmacokinetics, and pharmacodynamics of ALLO-316 in patients with advanced or metastatic clear cell renal cell carcinoma (RCC).
The FDA previously granted ALLO-316 Fast Track Designation (FTD) based on its potential to address the unmet need for patients with difficult to treat RCC who have failed standard therapies. Metastatic solid tumors have historically been a challenge regardless of treatment modality, and the five-year survival rate for patients with advanced kidney cancer is less than 15%, highlighting the need for innovation.
CF1, Allogene’s commercial scale manufacturing facility located in Newark, California is fully operational and producing GMP material with the intent of supplying ALLO-501A for the planned pivotal study as well as other clinical trials. CF1 is projected to have the ability to manufacture approximately 20,000 ALLO-501A AlloCAR T doses annually at scale. CF1 recently earned a LEED® Interior Design and Construction Gold designation from the U.S. Green Building Council (USGBS), a non-profit dedicated to sustainable building design and construction.
In July, Allogene announced the appointment of Stephen L. Mayo, Ph.D., a world-renowned expert in computational protein design, to the company’s Board of Directors. Dr. Mayo is the Bren Professor of Biology and Chemistry and Merkin Institute Professor at the California Institute of Technology in Pasadena, California. Dr. Mayo also serves on the Board of Directors of Merck & Co. and Sarepta Therapeutics, Inc.
