Akeso's Cadonilimab Shows Near-Complete Remission in Advanced Cervical Cancer

  • Akeso's cadonilimab demonstrated a 100% 24-month overall survival (OS) rate in patients with recurrent/metastatic cervical cancer (R/M CC) who achieved a complete response (CR) in a Phase II clinical trial.
  • The study, presented at ESGO 2026, included 99 efficacy-evaluable patients, with a median follow-up of 26.5 months.
  • Cadonilimab’s median progression-free survival (PFS) in CR patients was not reached, with a 12-month PFS rate of 84.6%.
  • The drug is already approved in China for first-line gastric cancer, first-line cervical cancer, and recurrent/metastatic cervical cancer.

Akeso’s cadonilimab represents a significant advancement in immunotherapy for cervical cancer, a disease with limited treatment options and poor prognosis. The near-complete remission observed in CR patients suggests a potential paradigm shift in treatment approaches, particularly for patients who have failed prior platinum-based chemotherapy. This success underscores the growing importance of bispecific antibodies and ‘IO 2.0’ strategies that overcome limitations of existing checkpoint inhibitors.

Regulatory Approval
The exceptional survival data will likely accelerate cadonilimab’s regulatory review in other markets, but acceptance will hinge on replicating these results in larger, global trials.
Commercial Adoption
The drug’s success will depend on clinicians’ willingness to adopt a novel bispecific antibody, particularly given existing standard-of-care treatments.
Pipeline Expansion
Akeso’s strategy of expanding cadonilimab’s indications across various cancer types and treatment settings will determine the drug’s long-term revenue potential.
