SciClone’s Tasurgratinib NDA Accepted by NMPA for FGFR2+ Biliary Tract Cancer

SciClone Pharmaceuticals Inc. (HKG: 6600) announced that the National Medical Products Administration (NMPA) has accepted for review its New Drug Application (NDA) for tasurgratinib succinate (E7090), a fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor licensed from Eisai Co., Ltd. (TYO: 4523). The filing seeks approval for unresectable biliary tract cancer with FGFR2 fusion/rearrangement following prior chemotherapy progression—a biomarker-defined orphan indication with no approved targeted therapies in China.

Trade Name (Japan)Tasfygo (approved September 2024)
Target IndicationUnresectable biliary tract cancer with FGFR2 fusion/rearrangement; post-chemotherapy progression
Licensing DealFebruary 2025 – SciClone secured exclusive China rights

Target Biology & Mechanism

FeatureTasurgratinib SpecificationClinical Rationale
Kinase SelectivityFGFR1, FGFR2, FGFR3 inhibitionBroad FGFR coverage; FGFR2 fusion-specific efficacy
Driver MutationsFGFR2-AHCYL1, FGFR2-BICC1, FGFR2-TXLNA, FGFR2-KCTD1 fusions/rearrangementsOncogene addiction in cholangiocarcinoma; constitutive FGFR2 activation
MechanismBlocks constitutively activated FGFR2 signalingTumor growth inhibition; apoptosis induction
Japan ValidationApproved September 2024 as TasfygoRegulatory precedent; established efficacy/safety profile

Market Context & Strategic Positioning

FactorMarket Analysis
Biliary Tract Cancer Burden>180,000 new cases annually in China; 10-15% harbor FGFR2 fusions/rearrangements – addressable population ~18,000-27,000 patients
Unmet NeedNo approved FGFR inhibitors in China for biliary cancer; standard chemotherapy (gemcitabine/cisplatin) offers limited durability
Competitive LandscapePemigatinib (Incyte) and futibatinib (Taiho) approved in US/EU; tasurgratinib first Japan-approved, now China-bound
SciClone StrategyIn-licensing proven assets from Japanese innovators (Eisai, Taiho); leverages regulatory expertise and hospital relationships for rapid commercialization
Biomarker-Defined MarketCompanion diagnostic requirement creates prescription control and premium pricing vs. chemotherapy

Forward‑Looking Statements
This brief contains forward‑looking statements regarding tasurgratinib NMPA approval timelines, SciClone’s commercial execution in biliary tract cancer, and competitive dynamics with pemigatinib and futibatinib in China. Actual results may differ due to regulatory review delays, FGFR2 biomarker testing adoption rates, and pricing negotiations with national reimbursement programs.-Fineline Info & Tech
