ImCheck to Present New Positive Data on ICT01 Monotherapy in Hematological Cancers at ESMO 2023

ImCheck

Oct 16, 2023 - Marseilles, France - ImCheck Therapeutics announced today that updated data from its ongoing Phase I/IIa clinical trial EVICTION will be presented at the European Society for Medical Oncology (ESMO) Congress in an oral session on October 22nd in Madrid. The presentation (822O) entitled: “Activation of γ9δ2 T Cells by ICT01 as a Novel Immunotherapeutic Approach for Relapsed/Refractory Hematologic Cancers (EVICTION Study)” will provide safety and patient response results from the Phase I dose escalation portion of the EVICTION trial of ImCheck’s lead antibody, ICT01, administered as a monotherapy to relapsed/refractory patients with hematological cancers, primarily Acute Myeloid Leukemia (AML).

EVICTION is an open-label Phase I/IIa trial assessing ICT01, a humanized anti-BTN3A monoclonal antibody that selectively activates γ9δ2 T cells, as a monotherapy in solid and hematological tumors, and as a combination therapy with pembrolizumab in solid tumors. The Phase 1 dose escalation study in relapsed/refractory hematological cancers included 26 patients who failed all available standard of care, 24 of which had acute myeloid leukemia, 1 with diffuse large B-cell lymphoma and 1 with follicular lymphoma. The reported data did not reveal any dose-limiting toxicities and demonstrated a disease control rate of 30% among the 10 evaluable patients at week 8. Notably, ICT01 treatment safely induced the activation and migration of γ9δ2 T cells from the blood within hours of dosing, suggesting effective target engagement.

Based on these results, the company has started evaluating ICT01 in combination with Venetoclax/azacitidine in a Phase IIa expansion cohort in first-line AML patients.
