Allogene Therapeutics Announces Three Poster Presentations from its Next Generation AlloCAR T™ Platform at the Society for Immunotherapy of Cancer (SITC) Annual Meeting

• Spotlight on Novel, Targeted Technologies to Enhance Engraftment, Expansion and Persistence of AlloCAR T™ Cells
  • Demonstration of Dagger™ Technology to Engineer CAR T cells to Selectively Eliminate CD70 Positive, Allo-Reactive Host Immune Cells
  • Evaluation of Cloak™ Technology to Engineer Allogeneic Cells from Detection by the Host Immune System
• Preclinical Validation of ALLO-182, an AlloCAR T™ Candidate Targeting Claudin18.2 for the Treatment of Gastric and Pancreatic Cancers

SOUTH SAN FRANCISCO, Calif., Sept. 27, 2023 (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 announced three preclinical poster presentations at the Society for Immunotherapy of Cancer (SITC) Annual Meeting November 1-5, 2023, in San Diego, CA. These presentations will focus on the Company’s next generation AlloCAR T platform technologies and the foundation for an early-stage solid tumor product candidate, ALLO-182.

“We are excited to share some of the groundbreaking work from our research team as we define next generation platform technologies that are designed to enhance engraftment and expansion of our AlloCAR T^TM product candidates,” said Zachary Roberts, M.D., Ph.D., Executive Vice President, Research & Development and Chief Medical Officer. “We believe this important and foundational work could expand the potential of off-the-shelf CAR T products by improving their persistence and anti-tumor activity across multiple targets while also creating a path to reducing the intensity of conditioning therapy.”
