The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of KIN-3248, an oral small molecule FGFR inhibitor, in adults with advanced tumors harboring FGFR2 and/or FGFR3 gene alterations.

Official Title

A Phase 1/1b, Open-label, Multicenter Study to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Anti-tumor Activity of KIN-3248 in Participants With Advanced Tumors Harboring FGFR2 and/or FGFR3 Gene Alterations


This is a two-part, open label, multi-center, dose escalation and dose expansion study in participants with advanced tumors harboring FGFR2 and/or FGFR3 gene alterations.

Part A (dose escalation) is aimed at evaluating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of KIN-3248, and determining the maximum tolerated dose (MTD) of daily dosing of KIN-3248.

Part B (dose expansion) may open once either the MTD and/or a biologically active dose of KIN-3248 is identified. Part B is aimed at evaluating the safety and efficacy of KIN-3248 at the recommended dose and schedule in participants with cancers harboring FGFR2 and/or FGFR3 gene alterations, including intrahepatic cholangiocarcinoma (ICC), urothelial cancer (UC), and other solid tumors.
