Highly differentiated programs stemming from gamma delta 1 tissue tropism and unique mechanism of action, combined with proprietary molecular engineering and armoring

ADI-925, a novel engineered chimeric adaptor (CAd) gamma delta T cell product candidate, is engineered to provide broad antitumor activity in multiple heme and solid malignancies; IND submission expected second half of 2023

Four differentiated chimeric antigen receptor (CAR) and CAd programs targeting several hematologic and solid malignancies featured at SITC

REDWOOD CITY, CA & BOSTON, MA, USA I November 07, 2022 I Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for cancer, today announced that positive preclinical data from four new pipeline programs will be featured at poster presentations at the Society for Immunotherapy of Cancer (SITC) 37th Annual Meeting on November 10-11, 2022.

“The emerging pipeline to be presented at SITC represents Adicet’s concerted efforts to design and deliver best-in-class gamma delta T cell therapies,” said Chen Schor, President and Chief Executive Officer of Adicet Bio. “The new programs represent an exciting step in our evolution as a company, and we look forward to initiating additional preclinical studies designed to support the submission of investigational new drug applications to advance our first-in-class allogeneic CAR and CAd gamma delta T cell therapy product candidates for a variety of cancer indications, including solid tumors.”

“The new pipeline programs have been carefully selected by integrating aspects of gamma delta 1 tissue homing, differentiated mechanisms of action, targeting enhancement and engineered armoring. Our innovative CAd and de novo CAR programs have illustrated increased proliferative potential, cytotoxicity, tumor homing, and inhibition of tumor growth in preclinical models,” commented Blake T. Aftab, Ph.D., Chief Scientific Officer at Adicet Bio. “We are motivated by these encouraging results and look forward to advancing therapeutic options for patients with hematologic and solid tumor malignancies.”
