Akeso Inc. has announced the initiation of a Phase III clinical trial involving ivonescimab, a PD-1/VEGF bispecific antibody, in combination with docetaxel for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) that has progressed following PD-1/L1 inhibitors and platinum-based chemotherapy. This pivotal study, AK112-305/HARMONi-8A, recently dosed its first patient. Ivonescimab is notable for being the only bispecific immunotherapy antibody currently in Phase III registration trials for immunotherapy-resistant lung cancer. The trial aims to provide a novel treatment option for patients with IO-resistant NSCLC, leveraging the synergistic effects of targeting both PD-1 and VEGF pathways to reactivate anti-tumor immune responses. The results of this ongoing study have not yet been presented.
