HONG KONG, May 26, 2026 /PRNewswire/ — Akeso, Inc. (9926.HK) (“Akeso” or the “Company”) announced that more than 40 clinical studies of its oncology portfolio will be presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 29 – June 2 in Chicago, Illinois. Notably, the presentations include one Late-Breaking Abstract (LBA) selected for the prestigious Plenary Session, alongside four Oral or Rapid Oral presentations.
The datasets featured at ASCO 2026 primarily highlight the Company’s core first-in-class bispecific antibodies — cadonilimab (PD-1/CTLA-4) and ivonescimab (PD-1/VEGF) — along with other novel therapeutic antibodies such as ligufalimab, a next-generation CD47 monoclonal antibody. These presentations include several potentially practice-changing datasets across multiple tumor types.
A pivotal highlight will be the Phase III overall survival (OS) results from the HARMONi-6 study, evaluating the survival advantage of ivonescimab combined with chemotherapy versus a PD-1 inhibitor combined with chemotherapy in the first-line setting for advanced squamous non-small cell lung cancer (sq-NSCLC). Additional notable presentations feature ivonescimab in small-cell lung cancer (SCLC) that has progressed after first-line chemoimmunotherapy, ivonescimab plus chemotherapy in first-line metastatic colorectal cancer (mCRC) from a global Phase II interim analysis, alongside cadonilimab-based regimens in renal cell carcinoma, melanoma, colorectal cancer, head and neck cancer, gynecologic malignancies, and biliary tract cancer.
The maturity and breadth of these datasets underscore the success of Akeso’s innovation engine, demonstrating the clinical benefits of the Company’s differentiated bispecific antibody platform to the international oncology community.
