Erdafitinib Monotherapy or in Combination With Cetrelimab in Muscle-invasive Bladder Cancer Patients With Fibroblast Growth Factor Receptor (FGFR ) Gene Alterations

Summary

Erdafitinib (ERDA) alone or in combination with cetrelimab (CET) as neoadjuvant treatment (prior to surgery) in subjects with muscle-invasive bladder cancer (MIBC) whose tumours express Fibroblast Growth Factor Receptor (FGFR )gene alterations and are ineligible for or refuse cisplatin based neoadjuvant chemotherapy.
