Summary
The main purpose of this study is to learn more about the safety, side effects, and
effectiveness of Vepugratinib by itself or when it is combined with other medicines that
treat cancer. Vepugratinib may be used to treat cancer of the cells that line the urinary
system and other solid tumor cancers that have a change in a particular gene (known as
the FGFR3 gene). Study participation could last up to approximately 6 years, depending on
which part of the study you join.
