NDA Acceptance in China for Fanregratinib

HUTCHMED Announces NDA Acceptance in China with Priority Review Status for Fanregratinib in Second-Line Intrahepatic Cholangiocarcinoma

• NDA supported by results from a Phase II registration trial in China -
• Second most common form of liver cancer after hepatocellular carcinoma, with generally poorer long-term survival in comparison -

Hong Kong, Shanghai & Florham Park, NJ - Monday, December 29, 2025: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM:​HCM; HKEX:​13) today announces that the New Drug Application ("NDA") for fanregratinib (HMPL-453) for the treatment of adult patients with advanced, metastatic or unresectable intrahepatic cholangiocarcinoma ("ICC") with fibroblast growth factor receptor ("FGFR") 2 fusion/rearrangement who have previously received systemic therapy has been accepted and granted priority review by the China National Medical Products Administration ("NMPA").

Fanregratinib (HMPL‑453) is a novel, selective, oral inhibitor targeting FGFR 1/2/3. ICC is a highly aggressive malignancy arising from the intrahepatic biliary epithelium. It accounts for 8.2-15.0% of primary liver cancers, and consequently it is the second most common type after hepatocellular carcinoma. In recent years, the incidence of ICC has continued to rise, with a 5-year overall survival rate of approximately 9%.[1] Approximately 10-15% of ICC patients globally have tumors harboring FGFR2 fusions or rearrangements.[2],[3]

This NDA is supported by data from a single-arm, multi-center, open-label, Phase II registration study in China. The study has met its primary endpoint of objective response rate (ORR). Results from the secondary endpoints including progression-free survival (PFS), disease control rate (DCR), duration of response (DoR) and overall survival (OS) also support the primary endpoint findings. Full results will be submitted for presentation at an upcoming scientific conference. Additional details may be found at clinicaltrials.gov using identifier NCT04353375.

About Fanregratinib

Fanregratinib (HMPL‑453) is a novel, highly selective and potent inhibitor targeting FGFR 1, 2 and 3. Aberrant FGFR signaling has been found to be a driving force in tumor growth, promotion of angiogenesis and resistance to anti-tumor therapies. Abnormal FGFR gene alterations are believed to be the drivers of tumor cell proliferation in several solid tumor settings. HUTCHMED currently retain all rights to fanregratinib worldwide.
