Brief Summary
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 advancedat a late stage, far along/metastatic urothelial carcinomacancer arising from tissues that line organs of the bladdera hollow, muscular sac in the pelvis that stores urine and urinary tract and other advanced solid tumors.
