Akeso IncPhase II trial shows ligufalimab combination improves survival and response rates in AML.

Akeso announced that its anti-CD47 antibody ligufalimab combined with azacitidine and venetoclax demonstrated a significant trend toward survival benefit and deep responses in a randomized Phase II trial for treatment-naïve AML patients ineligible for intensive chemotherapy. At a median follow-up of 10 months in the ligufalimab group and 8.8 months in the control group, median event-free survival was 9.1 months versus 6.9 months, and median overall survival was not reached versus 8.3 months, both with a hazard ratio of 0.46. The objective response rate was 80.0% versus 66.7%, and the composite complete response rate was 56.7% versus 53.3%, with a higher rate of MRD negativity in the ligufalimab arm. The safety profile was comparable between arms, with anemia occurring in 46.7% of the ligufalimab group versus 50.0% in the control group. Ligufalimab has received Orphan Drug Designation from the U.S. FDA for AML and is the first anti-CD47 monoclonal antibody worldwide to enter a registrational Phase III trial in solid tumors.
