Description

Summary

This study is being done to see how well two drugs (enfortumab vedotin and pembrolizumab) work together alone or with platinum chemotherapy to treat patients with urothelial cancer. The study will compare these drugs to other drugs that are usually used to treat this cancer (standard of care). The patients in this study will have cancer that has spread from their urinary system to other parts of their body.

Official Title

An Open-label, Randomized, Controlled Phase 3 Study of Enfortumab Vedotin in Combination With Pembrolizumab With or Without Chemotherapy, Versus Chemotherapy Alone in Previously Untreated Locally Advanced or Metastatic Urothelial Cancer

Details

This study is being conducted to evaluate the combination of enfortumab vedotin + pembrolizumab, with or without platinum-containing chemotherapy, versus standard of care gemcitabine + platinum-containing chemotherapy, in subjects with previously untreated locally advanced or metastatic urothelial cancer.

Enfortumab vedotin may be administered for an unlimited number of cycles until a protocol defined reason for study discontinuation occurs. Pembrolizumab may be administered for a maximum of 35 cycles or a protocol-defined reason for study discontinuation occurs, whichever is first. Cisplatin, carboplatin, and/or gemcitabine may be administered for a maximum of 6 cycles or a protocol-defined reason for study discontinuation occurs, whichever is first.
