Akeso Reports 100% R0 Resection Rate in Phase II Cadonilimab Study for Resectable Gastric Cancer

Akeso Inc. announced results from a Phase II clinical study (COMPASSION-25) evaluating its PD-1/CTLA-4 bispecific antibody, cadonilimab, in combination with the SOX regimen as neoadjuvant therapy for resectable gastric or gastroesophageal junction adenocarcinoma. The data, presented at the 2025 ESMO Asia Congress, showed a 100% R0 resection rate among patients who underwent surgery, with 85.7% achieving primary tumor downstaging and 75.0% achieving nodal downstaging. The overall pathologic complete response (pCR) rate was 28.6%, and the major pathologic response (MPR) rate was 71.4%. Safety findings were consistent with previously known profiles, and no new safety signals were observed. Akeso Inc. is also conducting a pivotal Phase III trial (AK104-310/COMPASSION-33) of cadonilimab combined with SOX for perioperative treatment in this patient population.
