ImCheck Achieves the Primary Objectives of Phase I of the EVICTION-2 Trial of ICT01 in Combination with Low Dose IL-2, Data Presented at AACR 2023
April 18, 2023 - ImCheck Therapeutics announced today data from its ongoing Phase I/IIa clinical trial EVICTION-2 at the American Association for Cancer Research (AACR) Annual Meeting 2023 in a poster presentation (CT179) titled: “First-in-Human Study of ICT01, an Anti-BTN3A Activating Monoclonal Antibody in Combination with Low Dose IL-2 in Patients with Advanced Solid Tumors (EVICTION-2 Study)”. As described in the poster, ImCheck’s lead antibody ICT01, administered at doses ranging from 1 to 75 mg, combined with low-dose subcutaneous IL-2 safely induced multi-cycle expansion of γ9δ2 T cells in 11/11 evaluable patients with no dose limiting toxicities and no new safety events observed. The combination also generated innate and adaptive immune stimulation characterized by the activation, mobilization, and expansion of CD8 T cells, NKs and granulocytes. Taken together, these data demonstrate achievement of the primary objectives of Phase I of the study, support that this combination could be a novel approach to maximize γ9δ2 T cell-mediated antitumor efficacy, and set the foundation for the Phase IIa portion of EVICTION-2.
