SOUTH SAN FRANCISCO, Calif., Nov. 02, 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 September 30, 2022.

The Company also announced an in-person and virtual Research & Development Showcase on Tuesday, November 29, 2022 in New York City. This event will discuss the Company’s CD19 program and data supporting the launch of ALPHA2, the first allogeneic CAR T Phase 2 clinical trial as well as updated data from the UNIVERSAL trial with single dose ALLO-715 and next steps for the program.

“We are incredibly proud of our teams and their strong execution which have enabled an industry first – the initiation of our potentially pivotal Phase 2 ALPHA2 trial,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “Our leading AlloCAR T programs ALLO-501A and ALLO-715 directed at CD19 and BCMA, respectively, have made substantial progress in 2022. We look forward to providing a comprehensive update on this progress at our upcoming R&D Showcase at the end of the month.”

Pipeline Updates

CD19 Program

Allogene has initiated the industry’s first potentially pivotal allogeneic CAR T Phase 2 clinical trial of ALLO-501A (ALPHA2 trial) in patients with relapsed/refractory (r/r) large B-cell lymphoma (LBCL). The single-arm trial will utilize a single dose of ALLO-501A at 120 million CAR+ cells with a lymphodepletion regimen (FCA90) comprised of fludarabine (30 mg/m2/day x 3 days) and cyclophosphamide (300 mg/m2/day x 3 days) plus ALLO-647 (90 mg). The ALPHA2 trial will enroll approximately 100 patients who have received at least two prior lines of therapy and have not received prior anti-CD19 therapy. The primary endpoint of this trial is overall response rate (ORR) and the key secondary endpoint is duration of response (DoR).

The Company is in the process of initiating the EXPAND trial, a separate registrational trial that is intended to demonstrate the contribution of ALLO-647 to the standard fludarabine and cyclophosphamide lymphodepletion regimen. Patients will be randomized to receive the same single 120 million cell dose of ALLO-501A as in the ALPHA2 trial and either lymphodepletion with fludarabine and cyclophosphamide alone (control arm) or the same lymphodepletion regimen of the ALPHA2 trial (active arm). The trial is expected to enroll approximately 70 patients with r/r LBCL. The primary endpoint of this trial is progression free survival, and the key secondary endpoints are ORR, DoR, and the safety of ALLO-647.

Allogene’s Alloy™ manufacturing process will be deployed in the ALPHA2 and EXPAND trials. Updated clinical data from the CD19 program will be provided at the Company’s R&D Showcase on November 29, 2022.

BCMA Program

The Phase 1 UNIVERSAL trial of ALLO-715 continues enrolling patients with r/r multiple myeloma (MM). The Company will provide a clinical update from UNIVERSAL focused on a single dose ALLO-715 and discuss next steps for the program at the R&D Showcase.

Solid Tumor Program

ALLO-316, the Company’s first AlloCAR T candidate for solid tumors, targets CD70 and is being studied in patients with advanced or metastatic clear cell renal cell carcinoma (RCC) in the Phase 1 TRAVERSE trial.

Corporate Highlights

CAR T Together™

The Company launched CAR T Together, a first-of-its-kind effort comprised of leading clinical trial investigators who represent the field of clinicians committed to supporting the development of off-the-shelf CAR T products to make CAR T therapy scalable and more accessible to patients with certain cancers. CAR T Together was created in response to several real-world access challenges that have emerged since the commercial introduction of autologous CAR T five years ago, highlighted by a new survey¹ of U.S. based academic centers specializing in the administration of CAR T. This survey found that 82% of respondents agreed that CAR T therapies have changed how they manage aggressive cancers, but extensive wait times and manufacturing limitations keep many eligible patients from receiving treatment. Additional survey results revealed:

• Only half of late-stage cancer patients who are eligible for currently FDA approved autologous CAR T therapies receive treatment.
• Of those patients eligible for treatment, only 12% are able to receive treatment within one month, with approximately 40% waiting three to six months or longer to receive treatment as their disease worsens.
• For eligible patients, disease progression, manufacturing capacity and comorbidities were the top barriers.
• Increased patient demand, manufacturing capacity and time to treatment are cited by respondents as the three biggest challenges facing CAR T adoption in the future.

CAR T Together aims to support innovation and bring awareness to clinical trials that may ultimately lead to the availability of an allogeneic CAR T product for patients. Learn more at www.CARTTogether.com.
