What this study is about

Researchers are testing if a drug called disitamab vedotin, alone or with pembrolizumab, works to treat urothelial cancer that expresses HER2. The trial will also test how safe the drug is for participants and what side effects happen when participants get the drug.

Simplified from trial records by PatientMatch.
