SOUTH SAN FRANCISCO, Calif., Nov. 07, 2024 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer and autoimmune disease, today provided corporate updates and reported financial results for the quarter ended September 30, 2024.

“We are proud of the progress made in the third quarter of 2024 to advance our investigational allogeneic cell products in key “firsts” – our first-line consolidation trial in large B-cell lymphoma with cema-cel, ALLO-316 as the first allogeneic CAR T product candidate to demonstrate positive results in solid tumors, and the first CD19/CD70 dual CAR T candidate specifically designed for autoimmune disease,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “We believe these efforts have the potential to redefine treatment paradigms, tailoring therapies to meet the unique needs of large patient populations, and enabling broader real-world adoption. Allogene remains dedicated to driving innovation that improves outcomes for patients with both cancer and autoimmune diseases.”

Program Updates

Cema-Cel: Pivotal ALPHA3 1L Consolidation Trial in Large B Cell Lymphoma (LBCL)

The pivotal Phase 2 ALPHA3 trial is the main focus for the Company. The trial was initiated in June 2024 and now has almost 30 sites activated and screening for patients with minimal residual disease (MRD).

This groundbreaking study is evaluating the use of cemacabtagene ansegedleucel (cema-cel) as part of the first line (1L) treatment regimen for patients with LBCL who are likely to relapse after standard 1L treatment. ALPHA3 is the first pivotal trial to offer CAR T as part of 1L treatment consolidation.

This innovative ALPHA3 trial will identify patients at high risk for relapse after 1L treatment by utilizing Foresight CLARITY™ powered by PhasED-Seq™, a novel and highly accurate Investigational Use Only (IUO) test for MRD. This randomized trial will enroll approximately 240 patients and is designed to demonstrate a meaningful improvement in event free survival (EFS) in patients treated with cema-cel relative to patients who receive the current standard of care (observation). ALPHA3 is expected to complete enrollment in 1H 2026. Efficacy analyses are expected to occur in 2026 and will include an interim EFS analysis monitored by the independent Data Safety Monitoring Board (DSMB) in 1H 2026 and the data readout of the primary EFS analysis by YE 2026. A potential biologics license application (BLA) submission is targeted for 2027.

ALLO-329: CD19/CD70 Dual CAR with Dagger^® Technology in Autoimmune Disease (AID)

The Company will present pre-clinical data for its next-generation investigational AlloCAR T candidate for autoimmune indications, ALLO-329, at the American College of Rheumatology’s annual meeting, ACR Convergence 2024, November 18, 2024, in Washington, D.C.

ALLO-329 offers a novel approach to treating autoimmune diseases as the first allogeneic CD19/CD70 dual CAR T product specifically designed to target CD19+ B-cells and CD70+ activated T-cells, both of which are key players in autoimmune diseases. The investigational product utilizes CRISPR-based site-specific integration and incorporates the Company’s clinically validated Dagger technology, which aims to reduce or eliminate the need for lymphodepletion, believed to be a potentially significant obstacle to the wider adoption of CAR T therapies in autoimmune applications.

The Company plans to file an investigational new drug (IND) application in Q1 2025 and expects to have proof-of-concept by YE 2025.

ALLO-316: TRAVERSE Trial in Renal Cell Carcinoma (RCC)

The Company will present an update to the ongoing Phase 1 TRAVERSE trial in an oral presentation at the 2024 International Kidney Cancer Symposium (IKCS, November 8, 2024) and at a poster session at the Society for Immunotherapy of Cancer's (SITC) Annual Meeting (November 9, 2024). The trial evaluates ALLO-316, the Company’s first AlloCAR T product candidate for the treatment of solid tumors. The Phase 1 TRAVERSE trial is enrolling patients with advanced or metastatic renal cell carcinoma (RCC) who have progressed following treatment with an immune checkpoint inhibitor and VEGF-targeting therapy. These presentations highlight strong evidence of anti-tumor activity of ALLO-316 following standard FC (fludarabine (30 mg/m2) and cyclophosphamide (500 mg/m2)) lymphodepletion in patients with CD70 positive RCC tumors.

As of the October 14, 2024 data cutoff, 39 patients had been enrolled in the ongoing Phase 1 trial, of which 26 were confirmed to have CD70 positive RCC and were evaluable for efficacy outcomes. The median time from enrollment to the start of therapy was five days. Data from dose escalation cohorts as well as a newly opened Phase 1b expansion cohort are included in the presentations. The Phase 1b expansion cohort is evaluating safety and efficacy of ALLO-316 at DL2 (80M CAR T cells) following a standard FC lymphodepletion.

Following a single infusion of ALLO-316 in heavily pretreated patients, the trial demonstrated best Overall Response Rate (ORR) of 50% and Confirmed Response Rate of 33% in those patients with CD70 Tumor Proportion Score (TPS) of ≥50% who received the Phase 1b expansion regimen. Patients with a TPS of ≥50% comprise the majority of patients with advanced or metastatic RCC. Of those with a TPS ≥50, 76% (16/21) experienced a reduction in tumor burden. Two of six (33%) patients with high TPS who received the Phase 1b expansion regimen showed durable responses ongoing at ≥4 months.

The most common all-grade adverse events were cytokine release syndrome (CRS) (with only one grade ≥3), fatigue (59%), neutropenia (56%), decreased white blood cell count (54%), anemia (51%), and nausea (51%). Immune effector cell-associated neurotoxicity syndrome (ICANS) was minimal at 8% and no graft-versus-host disease (GvHD) occurred.

Two dose limiting toxicity (DLT) events of autoimmune hepatitis and cardiogenic shock were reported. Each event occurred in two separate participants who received FCA (FC plus ALLO-647) lymphodepletion and DL2 of ALLO-316. Three Grade 5 treatment-related adverse events were reported: 1) cardiogenic shock, which was one of the two DLT events; 2) sepsis from multi-drug resistant Klebsiella pneumoniae in a participant who received DL4 of ALLO-316 - this participant had a prior episode of muscle abscess and bacteremia from the same multi-drug resistant Klebsiella and was receiving anakinra and dexamethasone for hyperinflammation; and 3) failure to thrive in a participant 16 months after treatment with ALLO-316 - this subject had tumor response of stable disease (SD) at month 12 and no interval scans to evaluate disease status prior to death.

On October 29, 2024, the Company announced that it had received Regenerative Medicine Advanced Therapy (RMAT) designation for ALLO-316 for adult patients with advanced or metastatic RCC. The RMAT designation was based on Phase 1 clinical data from the TRAVERSE trial indicating the potential of ALLO-316 to address the unmet need for patients with difficult-to-treat RCC who have failed multiple standard RCC therapies, including an immune checkpoint inhibitor and a VEGF-targeting therapy.
