Allogene Therapeutics presents preclinical data on allogeneic CAR T candidate

Allogene Therapeutics presented preclinical data on a novel off-the-shelf AlloCAR T product candidate targeting Claudin18.2-positive gastric and pancreatic tumors, at the Society for Immunotherapy of Cancer Annual Meeting November 1-5, 2023, in San Diego, CA. Data presented at SITC describes preclinical development of Allogene’s novel allogeneic CLDN18.2 CAR T product candidate with the potential to provide clinical benefit to patients with a single, off-the-shelf infusion. CLDN18.2 has emerged as a promising therapeutic target, with high expression in many types of epithelial tumors including gastric, esophageal, pancreatic and ovarian cancers. The preclinical evaluation identified candidates with potent activity in both short-term and repeat stimulation in vitro cytotoxicity assays. The lead IND candidates researched displayed robust antitumor activity at low cell doses in vivo against both subcutaneous and intraperitoneal gastric cancer models. Data suggest the existence of a therapeutic window and the potential to target CLDN18.2 with allogeneic off-the-shelf CAR T cells without significant off tumor toxicity. These data were the foundation for ALLO-182, currently in the IND-enabling phase of development. ALLO-182 together with ALLO-213, an allogeneic CAR T targeting DLL3, represent the company’s early-stage solid tumor product candidates.
