On November 3, 2020 LianBio, a biotechnology company focused on bringing paradigm-shifting medicines to patients in China and major Asian markets, reported that it has received clearance from the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) to conduct the Phase 3 PROOF trial of infigratinib, a potential first-line treatment for patients with locally advanced or metastatic unresectable cholangiocarcinoma with FGFR2 gene fusions (Press release, LianBio, NOV 3, 2020, View Source [SID1234570146]). LianBio has in-licensed infigratinib from BridgeBio Pharma, Inc. and is responsible for the registration application, clinical development and future commercial operations of the product candidate in Mainland China, Hong Kong and Macau.

Infigratinib is an investigational innovative, oral, selective and potent inhibitor of fibroblast growth factor receptor (FGFR) 1-3 with well-defined novel chemical structures and pharmacological effects, currently under Phase 3 global development by BridgeBio. In a separate clinical trial investigating infigratinib for patients with FGFR2-fusion positive cholangiocarcinoma who had progressed on gemcitabine-based therapy, infigratinib demonstrated an overall response rate of 27% [1]. The Phase 3 PROOF trial is a multicenter, randomized and controlled study designed to evaluate the pharmacokinetic profile, efficacy, and safety of infigratinib in patients with locally advanced or metastatic unresectable cholangiocarcinoma with FGFR2 gene fusions.
"This clearance by the China NMPA highlights the efficiency of LianBio’s operational model to bring cutting-edge technology to China," said Dr. Bing Li, Chief Executive Officer of LianBio. "Untreated cholangiocarcinoma is usually fatal, with only 50% of patients surviving for one year. Given the severity of the disease and increasing prevalence in China, there is a high urgency to bring innovative treatments to this patient population. Supported by our partner BridgeBio, LianBio is well-positioned to advance the clinical development of this product candidate."
