HUTCHMED Announces Positive Phase II Results for Fanregratinib in FGFR2-Altered Intrahepatic Cholangiocarcinoma

— Registration-enabling study demonstrated high clinically meaningful objective responses, achieving rapid and durable disease control —

— Fanregratinib holds promise as a new treatment option for pretreated advanced ICC patients harboring FGFR2-fusions/rearrangements —

HONG KONG and FLORHAM PARK, N.J., June 25, 2026 (GLOBE NEWSWIRE) -- HUTCHMED (China) Limited (“ HUTCHMED ”) (Nasdaq/AIM:HCM; HKEX:13) today announces results from the pivotal Phase II registration study of fanregratinib (HMPL-453) in patients with intrahepatic cholangiocarcinoma (“ICC”) will be presented at the European Society for Medical Oncology (ESMO) Gastrointestinal Cancers Congress taking place from July 1 to 4, 2026 in Munich, Germany.

Supported by data from the study, a New Drug Application (NDA) for fanregratinib for the treatment of adult patients with advanced, metastatic or unresectable ICC with fibroblast growth factor receptor (“FGFR”) 2 fusion/rearrangement who have previously received systemic therapy has been accepted for review and granted priority review by the China National Medical Products Administration (NMPA) in December 2025.

“The clinical reality for this patient population with advanced FGFR2–fusion/rearrangement ICC is highly challenging, as the entire cohort had progressed on prior chemotherapy, and a significant majority had prior immunotherapy exposure,” said Professor Jianming Xu of the Chinese PLA General Hospital and leading Principal Investigator of the study. “The results from this registration-enabling trial represent an important milestone in the targeted treatment landscape for FGFR2-altered ICC. The objective response rate and survival metrics achieved by fanregratinib clearly support its therapeutic value as a potent, selective oral treatment option. We are encouraged by these findings and hope to see this innovation translate into clinical practice to address a critical need in gastrointestinal oncology.”

This pivotal study is a single-arm, multi-center, open-label, Phase II registration clinical trial conducted across 53 sites in China to evaluate the efficacy, safety and pharmacokinetic of fanregratinib in treating advanced ICC patients with FGFR2 fusion/rearrangement ( NCT04353375 ). All patients had received at least one line of systemic therapy, of which all had received chemotherapy and 72% had received immunotherapy. The study has met its primary endpoint, demonstrating an Independent Review Committee (IRC)-assessed objective response rate (ORR) of 42.5% (95% CI: 30.0%–53.6%). Key secondary endpoints showed consistent clinical activity and a rapid onset of action, with a median time to response of 1.4 months. Median duration of response (DoR) was 6.9 months (95% CI: 5.6–8.5) and disease control rate (DCR) reached 83.9% (95% CI: 74.5%–90.9%). Furthermore, the median progression-free survival (PFS) was 6.9 months (95% CI: 4.1–8.2), while the median overall survival (OS) was 16.6 months (95% CI: 12.4–16.6).

Fanregratinib exhibited a manageable safety profile consistent with the known mechanism of selective FGFR inhibitors. Drug-related adverse events of Grade 3 or greater were reported in 48.3% of patients, with the most common being elevations in liver enzymes and palmar-plantar erythrodysesthesia syndrome (PPES). Treatment discontinuation due to drug-related adverse events was limited to 2.2% of patients, and no treatment-related deaths were recorded.

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.
