Enfortumab Vedotin and Pembrolizumab vs. Chemotherapy Alone in Untreated Locally Advanced or Metastatic Urothelial Cancer

Japan PMDA has approved enfortumab vedotin (Padcev) for the treatment of advanced urothelial cancer. The study will continue as a post marketing study in Japan. This study is being conducted to evaluate the combination of enfortumab vedotin + pembrolizumab 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 or carboplatin plus gemcitabine may be administered for a maximum of 6 cycles or a protocol-defined reason for study discontinuation occurs, whichever is first.
