Allogene Therapeutics to Present New Data Demonstrating the Potential of ALLO-316 in Heavily Pretreated Adult Patients with CD70 Positive Advanced Renal Cell Carcinoma (RCC) at the International Kidney Cancer Symposium (IKCS) and Society for Immunotherapy of Cancer (SITC) Annual Meeting

• ALLO-316, an “Off-the-Shelf” AlloCAR T^™ Anti-CD70 CAR T Product, is Currently Under Investigation in the Phase 1 TRAVERSE Trial for Patients with Renal Cell Carcinoma (RCC) Previously Treated with Immune Checkpoint Inhibitors and VEGF-Targeting Therapies
• Data Presented Advances Scientific Understanding and Applicability of the Dagger^® Technology as the Next-Generation Allogeneic Platform to Maximize the Potential of a Single Infusion, AlloCAR T Product
• Ongoing Phase 1 Data Supported the FDA’s Recent RMAT Designation for ALLO-316 as a Promising Treatment to Address an Unmet Medical Need for Adults with Advanced or Metastatic CD70 Positive RCC Who Have Failed Standard RCC Therapies

SOUTH SAN FRANCISCO, Calif., Nov. 05, 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 announced that it will present new data from the ongoing Phase 1 TRAVERSE trial at the 2024 International Kidney Cancer Symposium (IKCS) and the Society for Immunotherapy of Cancer’s (SITC) annual meeting. The trial evaluates ALLO-316, the Company’s first AlloCAR T product candidate for the potential treatment of solid tumors. These presentations will highlight data from 26 heavily pretreated patients with CD70 positive renal cell carcinoma (RCC) and will include details on the diagnostic and treatment algorithm used to mitigate treatment-associated hyperinflammatory response seen in some patients. The ongoing Phase 1 data supported the U.S. Food and Drug Administration’s (FDA) October 2024 decision to grant Regenerative Medicine Advanced Therapy (RMAT) designation for ALLO-316 based on clinical data from the TRAVERSE trial indicating its to address the unmet need for adult patients with advanced or metastatic CD70 positive RCC who have failed multiple standard RCC therapies, including an immune checkpoint inhibitor and a VEGF-targeting therapy. 

“We are looking forward to presenting the most recent Phase 1 data from our ongoing TRAVERSE trial at both SITC and IKCS,” said Zachary Roberts, M.D., Ph.D., EVP of Research & Development and Chief Medical Officer. “There is significant unmet need for these heavily pretreated patients with advanced RCC. In treating their disease, these patients rarely get any form of treatment break as their disease quickly progresses. This data highlights the potential of ALLO-316 to elicit a response from a single infusion, suggesting a breakthrough in allogeneic CAR T therapy for solid tumors. As the Phase 1 data matures, we plan to seek FDA’s input for the next stage of clinical development.”

Title: ALLO-316 in patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC): Updated safety and efficacy from the phase 1 TRAVERSE multicenter study
Presenter: Samer Srour, M.D., The University of Texas MD Anderson Cancer Center
Abstract Number: 322

The ongoing Phase 1 TRAVERSE trial is designed to evaluate the safety, tolerability, and activity of ALLO-316 in patients with advanced or metastatic RCC. The development of ALLO-316 continues to advance the scientific understanding and applicability of the Dagger technology as the next-generation allogeneic platform with the ability to maximize the potential of a one-time infusion. In April 2024, the Company announced a $15 million award from the California Institute for Regenerative Medicine (CIRM) to support the ongoing TRAVERSE trial with ALLO-316 in RCC.

About ALLO-316 (TRAVERSE)
ALLO-316, an AlloCAR T^™ investigational product, targets CD70 which is highly expressed in renal cell carcinoma (RCC). CD70 is also selectively expressed in several cancers, creating the potential for ALLO-316 to be developed across a variety of both hematologic malignancies and solid tumors. ALLO-316 utilizes the Dagger^® technology to optimize CAR T cell expansion and persistence to maximize the potential efficacy in solid tumors with a one-time infusion. The ongoing Phase 1 TRAVERSE trial is designed to evaluate the safety, tolerability, and activity of ALLO-316 in patients with advanced or metastatic clear cell RCC. In March 2022, the U.S. Food and Drug Administration (FDA) granted Fast Track Designation (FTD) to ALLO-316, and in October 2024 the FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to ALLO-316 based on its potential to address the unmet need for adult patients with CD70 positive advanced or metastatic RCC who have failed standard RCC therapies.
