Adicet Presents Preclinical Data at the ISCT Annual Meeting Highlighting Potential Advantages of the Non-Gene-Edited Approach for its Investigational Allogeneic Gamma Delta CAR T Cell Therapy Targeting CD20 for B Cell Malignancies
ADI-001 exhibited robust in vitro and in vivo tumor growth inhibition in multiple human lymphoma cell lines, with adaptive and innate mechanisms contributing to its anti-tumor activity
Non-gene-edited ADI-001 gamma delta CAR T cells demonstrated superior resilience to host versus graft targeting when compared to common gene-edited approaches
The extensive preclinical evaluation reported at ISCT observed that ADI-001 exhibited a predominantly naïve-like T cell memory phenotype, expressed multiple chemokine and innate-activating cell receptors and exhibited robust in vitro and in vivo tumor growth inhibition against multiple human lymphoma cell lines, with adaptive and innate activation pathways contributing to the anti-tumor activity of ADI-001.
Susceptibility to host versus graft targeting was also evaluated using mixed-lymphocyte reactions incorporating up to 13 different allogeneic lymphocyte samples. Non-gene-edited ADI-001 gamma delta CAR T cells demonstrated high levels of endogenous HLA-E expression in the unmodified state and were associated with superior resilience to lymphocyte-mediated clearance when compared to approaches commonly deployed in gene-edited allogeneic cell therapy platforms (β2MKO with or without HLA-E overexpression).
“In this first view comparing Adicet’s non-gene-edited gamma delta CAR T cells to alternative and popularly-reported gene editing strategies, we appreciate the lower preclinical susceptibility to host versus graft targeting demonstrated by non-gene-edited ADI-001,” said
