Adicet Bio’s new preclinical data highlighting ADI-270 selected for ASGCT

Adicet Bio “announced that an abstract featuring new preclinical data highlighting ADI-270, an armored allogeneic “off-the-shelf” gamma delta CAR (chimeric antigen receptor) T cell therapy candidate targeting CD70 positive cancers, has been selected for an oral presentation at the ASGCT 27th Annual Meeting taking place from May 7-11, 2024, in Baltimore, MD. The oral presentation will take place on May 10, 2024 in the Targeted Gene and Cell Therapy session, co-chaired by Adicet Bio’s Chief Scientific Officer, Blake Aftab, Ph.D. Findings from this study have further characterized and have provided comparative benchmarking for the mechanisms by which ADI-270 provides enhanced functionality and potency in CD70 positive expressing tumors such as clear cell renal cell carcinoma (ccRCC) and facilitates a robust anti-tumor effect that supports its continued development. The preclinical findings indicate: ADI-270 demonstrated potent in vitro cytotoxicity against multiple CD70 positive tumor cell lines expressing varying levels of CD70. ADI-270 demonstrated robust cytotoxicity against heterogeneous CD70 negative and CD70 positive tumor cell cultures, highlighting the potential of gamma delta CAR T cells to be effective against tumors with mixed antigen expression. ADI-270’s unique use of CD27-based targeting of CD70 demonstrated robust CAR-mediated killing in multiple cancer models including ccRCC, non-small cell lung cancer and T cell lymphoma, and including those models with lower levels of CD70 expression. ADI-270 inhibited tumor growth in the context of suppressive tumor microenvironment attributed to inclusion of dominant-negative transforming growth factor beta receptor and demonstrated resilience to clearance by host T cells attributed to the function of CD27-based CAR targeting of CD70 also expressed on host T cells. Robust anti-tumor effects in an in vivo model of ccRCC, such as tumor infiltration, proliferation, and effector function, were observed after administration, resulting in eradication of CD70 positive tumor cells.”
