IMM27M, a humanized Fc-engineered anti CTLA-4 antibody, in patients with advanced solid tumors: A phase I dose-escalation study (AACR 2024) - P1 | "The pre-clinical results showed IMM27M induced a significantly stronger anti-tumor activity than ipilimumab and resulted in complete tumor remission even at a low dose. This study is an open-label, multi-center, phase I dose-escalation study to evaluate the safety, tolerability, maximum tolerated dose/recommended dose for expansion, PK and anti-tumor activity in patients with advanced solid tumors. IMM27M monotherapy in general was well-tolerated at the dose levels evaluated and preliminarily single agent activity was seen in patients with heavily pretreated advanced solid tumors. The dose escalation study of IMM27M in advanced solid tumors is ongoing.Clinical trial information: NCT05235438."
