The purpose of this study is to evaluate recurrence-free survival (RFS) in participants treated with erdafitinib vs Investigator's Choice, for participants with high-risk non-muscle-invasive bladder cancer (NMIBC) who harbor fibroblast growth factor receptor (FGFR) mutations or fusions, and who recurred after bacillus calmette-guerin (BCG) therapy.
This study enrolls participants with high risk NMIBC and FGFR mutations or fusions. Erdafitinib is an oral pan-fibroblast growth factor receptor (FGFR) 1-4 inhibitor with demonstrated clinical activity in participants with solid tumors, including urothelial carcinoma, with alterations in the FGFR pathway. In Cohort 1, participants will be randomized to erdafitinib or to Investigators Choice (intravesical gemcitabine or intravesical mitomycin C \[MMC\] or hyperthermic MMC). The study consists of screening period, treatment phase, follow-up phase, and long-term extension phase.
Participants will receive erdafitinib orally beginning on Cycle 1 Day 1 until 2 years of treatment have been completed, disease recurrence, intolerable toxicity, withdrawal of consent, a decision by the investigator to discontinue treatment, or study termination, whichever occurs first. Each cycle is of 28 days.
Investigator's Choice treatment will be given once weekly for at least 4 doses of induction followed by monthly maintenance for at least 6 months.
