Akeso’s Ivonescimab Secures Fifth Breakthrough Therapy Designation for Biliary Tract Cancer in China

Akeso, Inc. (HKG: 9926) announced that Yidafang (ivonescimab) has been awarded Breakthrough Therapy Designation (BTD) by the Center for Drug Evaluation (CDE) of China’s NMPA for first‑line combination therapy of advanced biliary tract malignancies (BTC). This marks the fifth BTD for the world’s first PD‑1/VEGF bispecific antibody, expanding its oncology footprint beyond lung and breast cancer.

AssetIvonescimab (Yidafang) – PD‑1/VEGF bispecific antibody
DesignationBreakthrough Therapy Designation (BTD)
New IndicationFirst‑line combination therapy for advanced biliary tract malignancies (BTC)
BTD TallyFifth overall (3 lung cancer + 1 TNBC + 1 BTC)

Approved Indications & Reimbursement Status

IndicationApproval DateStatus
EGFR‑mutated non‑squamous NSCLC (post‑EGFR‑TKI progression)May 2024Approved; NRDL listed
PD‑L1‑positive advanced NSCLC (first‑line)April 2025Approved; NRDL listed
Biliary tract malignancies (first‑line combo)Feb 2026BTD granted; pivotal trial stage

Technology Profile & Mechanism of Action

  • Novelty: World’s first bispecific antibody simultaneously targeting PD‑1 (cancer immunotherapy) and VEGF (anti‑angiogenesis) in a single molecule
  • Mechanistic Synergy:
  • PD‑1 blockade – Reactivates T‑cell anti‑tumor immunity
  • VEGF inhibition – Normalizes tumor vasculature, enhances immune cell infiltration, and suppresses metastasis
  • Competitive Edge: Dual‑targeting reduces need for combination chemotherapy while potentially improving efficacy over PD‑1 monotherapy or PD‑1 + VEGF tyrosine kinase inhibitor combinations

Clinical & Commercial Implications

  • Biliary Tract Opportunity: BTC represents a high‑unmet‑need malignancy with limited effective first‑line options; BTD positions ivonescimab for priority review and accelerated approval pathway in China.
  • BTD Portfolio Validation: Five Breakthrough designations establish ivonescimab as a platform asset with broad mechanistic applicability across solid tumors, supporting Akeso’s global licensing strategy.
  • NRDL Inclusion Momentum: Existing NSCLC indications already on National Reimbursement Drug List demonstrate pricing negotiation success and market access foundation for future BTC approval.
  • Global Expansion Potential: BTD status strengthens data package for ex‑China regulatory submissions, particularly in hepatobiliary‑prevalent Asian markets and Western territories seeking novel BTC therapies.

Strategic Outlook
