Bladder Cancer Clinical Trial
Safety and Preliminary Anti-Tumor Activity of TYRA-300 in Advanced Urothelial Carcinoma and Other Solid Tumors With FGFR3 Gene Alterations
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of TYRA-300 in cancers with FGFR3 activating gene alterations, including locally advanced/metastatic urothelial carcinoma of the bladder and urinary tract and other advanced solid tumors.
This is a single arm, multi-part, phase 1/2 global trial studying TYRA-300, a novel, potent fibroblast growth factor receptor (FGFR) 3-selective tyrosine kinase inhibitor, in advanced/metastatic urothelial carcinoma of the bladder and urinary tract, that contain activating gene alterations of FGFR3. Phase 1 is a dose-escalation study to evaluate the safety, tolerability, and PK of TYRA-300 to determine the optimal and maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Phase 2 will evaluate the preliminary antitumor activity of TYRA-300 in cancers with FGFR3 activating gene alterations, including locally advanced/metastatic urothelial carcinoma of the bladder and urinary tract and other advanced solid tumors.
