Akeso, Summit cancer drug confirms lung cancer survival benefit
Akeso Biopharma and Summit Therapeutics announced on Thursday that their co-developed bispecific antibody, ivonescimab, met the key secondary endpoint of overall survival in an interim analysis of a Phase 3 clinical trial (HARMONi-2) in Chinese patients with non-small cell lung cancer. Results showed that patients treated with ivonescimab had significantly prolonged overall survival compared to those treated with Merck's pembrolizumab (Keytruda). Full data are expected to be presented at a lung cancer conference later this month.
