PALO ALTO, Calif. & SHANGHAI & PRINCETON, N.J.– LianBio, a biotechnology company dedicated to bringing paradigm-shifting medicines to patients in China and other major Asian markets, and BridgeBio Pharma, Inc. (Nasdaq: BBIO) today announced the first patient has been treated in a Phase 2a clinical trial of infigratinib in patients with locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma with fibroblast growth factor receptor-2 (FGFR2) gene amplification and other advanced solid tumors with FGFR genomic alterations.
“Infigratinib is a potent and selective FGFR inhibitor that has demonstrated compelling clinical activity across multiple tumor types with FGFR alterations,” said Yizhe Wang, Ph.D., chief executive officer of LianBio. “Given the disproportionately high prevalence rate of gastric cancer in China, LianBio is pursuing a region-specific development strategy focused on this area of great unmet need. This study marks LianBio’s first trial initiation and demonstrates our continued progress in delivering potentially transformational medicines to patients in Asia.”
TRUSELTIQ™ (infigratinib) is an oral selective inhibitor of FGFR1-3 that is approved in the United States for the treatment of patients with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a FGFR2 fusion or other rearrangement as detected by an FDA-approved test. It is also being further evaluated in clinical trials based on demonstration of clinical activity in patients with advanced urothelial carcinoma with FGFR3 genomic alterations. LianBio in-licensed rights from BridgeBio for infigratinib for development and commercialization in Mainland China, Hong Kong and Macau.
The Phase 2a trial is a multicenter, open-label, single-arm study in China designed to evaluate the safety and efficacy of infigratinib in patients with locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma with FGFR2 gene amplification and other advanced solid tumors with FGFR alterations. The primary endpoint is objective response rate (ORR). Secondary endpoints include duration of response, safety, disease control rate, progression-free survival and overall survival.
Preclinical data have demonstrated the potential infigratinib may have for patients with gastric cancer. These results, published in Cancer Discovery, demonstrated tumor regression in multiple in vivo FGFR2 amplified gastric models.1
“We believe that infigratinib could have a meaningful impact for people living with gastric cancer as well as many other cancers with FGFR alterations, and are pleased LianBio is initiating this clinical trial in China where more therapeutic options are needed to match the growing diagnosis rate,” said BridgeBio founder and chief executive officer Neil Kumar, Ph.D. “On the heels of TRUSELTIQ recently obtaining accelerated approval in the United States, we are hopeful that this trial will yield pivotal results in another subset of cancer patients as we continue to build our portfolio of oncology indications with the aim of reaching as many people in need as possible.”
