Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
Part A (dose escalation) - incidence of adverse events (AEs)
Time Frame: Initiation of study drug through 28 days after last dose (up to approximately 18 months)
Part B (dose expansion) - disease control rate (DCR): the proportion of participants who achieve stable disease, PR, or CR
Time Frame: Initiation of study drug until disease progression (up to approximately 36 months)
Part A (dose escalation) - incidence of dose limiting toxicities (DLTs)
Time Frame: Initiation of study drug through 28 days
Part B (dose expansion) - objective response rate (ORR): the proportion of participants who have achieved partial response (PR) or complete response (CR) according to RECIST v1.1
Time Frame: Initiation of study drug until disease progression (up to approximately 36 months)
Part B (dose expansion) - duration of response (DOR): the length of time between initial tumor response to documented tumor progression
Time Frame: Initiation of study drug until disease progression (up to approximately 36 months)
Part B (dose expansion) - progression-free survival (PFS): the length of time until documented tumor progression
Time Frame: Initiation of study drug until disease progression (up to approximately 36 months)
Secondary Outcomes
- Part A (dose escalation) - PK - time to reach maximum plasma concentration (Tmax) of KIN-3248(Initiation of study drug through Cycle 5 (up to approximately 4 months))
- Part A (dose escalation) - PK - area under the plasma concentration-time curve (AUC) of KIN-3248(Initiation of study drug through Cycle 5 (up to approximately 4 months))
- Part A (dose escalation) - PK - maximum plasma concentration (Cmax) of KIN-3248(Initiation of study drug through Cycle 5 (up to approximately 4 months))
