ADI-270 includes Adicet’s proprietary armoring technology and enhancements designed for improved persistence and durability within a solid tumor microenvironment (TME)
ADI-270 demonstrated potent anti-tumor activity in CD70+ cancers and improved resilience to clearance from host immune targeting
REDWOOD CITY, CA & BOSTON, MA, USA I May 18, 2023 I Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for cancer, today announced preclinical data highlighting ADI-270, an armored allogeneic “off-the-shelf” gamma delta CAR (chimeric antigen receptor) T cell therapy candidate targeting CD70+ cancers, at the 26th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) taking place from May 16-20, 2023, in Los Angeles, CA.
“We believe that ADI-270, combined with a third generation CAR and armoring technologies designed to improve persistence and resilience within the TME, may be able to overcome multiple barriers for realizing efficacy for cell therapies in solid tumors. Together with both innate and adaptive immune targeting and tumor infiltration, we believe ADI-270 can potentially improve clinical outcomes for patients,” said Dr. Blake Aftab, Ph.D., Chief Scientific Officer of Adicet. “These findings provide critical groundwork to support the continued clinical development of ADI-270 as a potentially meaningful therapeutic option.”
In this study, gamma delta T cells modified to express CD70 CAR were successfully generated and expanded without evident hindrances from CD70-mediated fratricide in the process. Data being presented included the following findings:
- ADI-270 demonstrated preclinical proof-of-concept as an armored allogeneic gamma delta CAR T cell therapy candidate utilizing the CD27 natural receptor in a third generation CAR format for targeting CD70-positive cancers.
- ADI-270 gamma delta 1 CAR T cells expressed a predominant naïve-like memory phenotype with potent in vitro cytotoxicity and production of proinflammatory cytokines against CD70+ tumor cell lines via multiple mechanisms.
- ADI-270 showed significant inhibition of tumor growth in CD70+ tumor cell lines, which was maintained in the presence of TGF beta inhibitory factor, and exhibited improved resistance to killing by host T cell rejection.
- ADI-270 also demonstrated marked biodistribution and infiltration into solid tumor models of renal cell carcinoma.
