SOUTH SAN FRANCISCO, Calif., February 23, 2022 – 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 and year ended December 31, 2021.
“The FDA hold placed upon our clinical programs presented us with an unexpected challenge during the fourth quarter. In responding to and resolving this challenge, our team continued to demonstrate the qualities of leadership, collaboration, innovation, and focus that are required to be a pioneer in the field of allogeneic T cell therapy. I am incredibly proud of our employees’ commitment and relentless belief in the potential for our products to improve the lives of patients,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “Our mission has been, and continues to be, the first to bring allogeneic CAR T products to the market in blood cancers and solid tumors. We believe we are on track and have what it takes to execute on this vision and look forward to advancing our broad portfolio of product candidates.”
Corporate Highlights
On January 10, 2022, Allogene announced that the U.S. Food and Drug Administration (FDA) had removed the clinical hold on all AlloCAR T clinical trials which was announced on October 7, 2021. After extensive investigation by Allogene, it was determined that the chromosomal abnormality detected in a single patient treated with ALLO-501A was unrelated to TALEN® gene editing or Allogene’s manufacturing process and had no clinical significance. The abnormality was not detected in any manufactured AlloCAR T product or in any other patient treated with the same ALLO-501A lot. The abnormality occurred after the cell product was administered and involved regions of the T cell receptor and immunoglobulin genes known to undergo rearrangement as part of the T cell or B cell maturation process.
Allogene has resumed clinical study activities on ALLO-715 and ALLO-605 for relapsed/refractory (R/R) multiple myeloma (MM), and ALLO-316 for advanced or metastatic clear cell renal cell carcinoma (RCC), and began enrolling patients earlier this month. Enrollment in the Phase 1 ALLO-501 ALPHA trial in R/R non-Hodgkin lymphoma (NHL) has completed accrual. The focus remains on preparing for the pivotal Phase 2 ALPHA2 trial of ALLO-501A in R/R Large B Cell Lymphoma (LBCL). Prior to the start of Phase 2, Allogene plans to resume enrollment in the Phase 1 study in order to offer AlloCAR T to patients in need.
Cell Forge 1 (CF1)
CF1, Allogene’s state-of-the-art manufacturing facility located in Newark, California is now fully operational and producing GMP material with the intent of supplying ALLO-501A for the planned pivotal study.
Pipeline Updates
Anti-CD19 Program
Phase 1 data from the ALPHA trial with ALLO-501 and ALPHA2 trial with ALLO-501A for the treatment of R/R NHL was presented at the 2021 Annual American Society of Hematology (ASH) Annual Meeting. Data from these trials continue to support the promise of Allogene’s platform to provide a safe and durable alternative to approved autologous CAR T therapies in CAR T naïve patients.
Highlights from the ASH 2021 presentation include:
•AlloCAR T was associated with consistent and 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).
•There were no relapses observed in LBCL CAR T naïve patients across trials who had achieved a complete response (CR) at six months with the longest ongoing CRs with ALLO-501 at 18+ months and ALLO-501A at 15+ months.
•One of the most critical advantages of AlloCAR T was further established with more than 97% of enrolled patients able to receive therapy with the median time from enrollment to initiation of treatment of five days in ALPHA and two days in ALPHA2.
Phase 2 Preparation:
The single-arm ALPHA2 trial is on track to begin mid-year 2022 with FDA discussions directed at finalizing clinical trial design and proactively accelerating activities that address Chemistry Manufacturing and Controls (CMC) requirements.
Allogene is developing ALLO-647, its proprietary anti-CD52 monoclonal antibody intended to enable expansion and persistence of AlloCAR T product candidates, including ALLO-501A. Allogene intends to launch a separate registrational trial for ALLO-647 at the time of the pivotal Phase 2 trial for ALLO-501A as part of the concurrent development plan. This trial is intended to demonstrate the safety of ALLO-647 along with its contribution to the overall benefit of the lymphodepletion regimen.
Anti-BCMA AlloCAR T Program
Allogene’s anti-BCMA strategy includes the Phase 1 UNIVERSAL trial, which has cohorts evaluating ALLO-715 as a monotherapy, consolidated dosing of ALLO-715 using ALLO-647 to selectively extend the window of lymphodepletion, and ALLO-715 in combination with SpringWorks Therapeutics’ investigational gamma secretase inhibitor, nirogacestat. The Phase 1 IGNITE trial is evaluating ALLO-605, Allogene’s first TurboCAR™ candidate. TurboCAR technology allows cytokine activation signaling to be engineered selectively into CAR T cells and has shown the ability to improve the potency and persistence of allogeneic cells in preclinical models. Activity in these trials has resumed and Allogene intends to provide a BCMA program clinical update by the end of 2022.
ALLO-715 UNIVERSAL Trial
Data from the UNIVERSAL trial with ALLO-715 as a monotherapy for the treatment of R/R MM was also presented at ASH 2021. The UNIVERSAL trial is the first allogeneic anti-BCMA CAR T to demonstrate safety and substantial efficacy in MM with response rates that are similar to the approved autologous CAR T therapy.
•The data presented at ASH demonstrated that ALLO-715 was well tolerated with no GvHD and a manageable safety profile.
•There was a 71% Overall Response Rate (ORR) at dose level 3 (320 million AlloCAR T+ cells) with lymphodepletion consisting of fludarabine/cyclophosphamide and ALLO-647
◦46% of patients achieved a Very Good Partial Response or better (VGPR+) including 25% Complete Response or Stringent Complete Response (CR/sCR).
◦92% of patients with VGPR+ were minimal residual disease (MRD) negative.
◦Median duration of response (DoR) was 8.3 months at the time of data cut-off.
•Importantly, the study highlighted the ability to initiate treatment within five days of enrollment and eliminate the need for bridging therapy.
Solid Tumor AlloCAR T Program
ALLO-316 (anti-CD70) – TRAVERSE Trial
•The Phase 1 trial for Allogene’s first AlloCAR T candidate for solid tumors, ALLO-316, is designed to evaluate the safety, tolerability, anti-tumor efficacy, pharmacokinetics, and pharmacodynamics of ALLO-316 in patients with advanced or metastatic clear cell RCC. Clinical trial activities have resumed.
