About this trial
The purpose of the study in Part 1 (dose escalation) and in Part 2 (dose expansion) is to determine the recommended Phase 2 dose(s) (RP2D\[s\]) and evaluate preliminary clinical efficacy. Part 3 (dose expansion) will confirm safety and preliminary clinical activity at the RP2D. Part 4 (RP2D expansion; MoonRISe-2) will assess the overall complete response (CR) in participants with intermediate-risk-non-muscle invasive bladder cancer (IR-NMIBC; means the cancer cells are only in the bladder's inner lining).
Eligibility criteria
Qualifiers
Muscle-invasive or recurrent, non-muscle-invasive urothelial carcinoma of the bladder
For selected Cohorts: Activating tumor pan-fibroblast growth factor receptor (FGFR) mutation or fusion, as determined by local or central testing, approved by the sponsor prior to the start of study treatment. Local tissue-based results (if already existing) from next-generation sequencing (NGS) or polymerase chain reaction (PCR) tests performed in Clinical Laboratory Improvement Amendments (CLIA) -certified or equivalent laboratories, or results from commercially available PCR or NGS tests
Cohorts 1 and 2: Bacillus Calmette-Guérin (BCG) experienced, or participants with no BCG experience because BCG was not available as a treatment option in the participant's location within the previous 2 years and is currently unavailable. Participants who received an abbreviated course of BCG due to toxicity are still eligible
Cohort 1 only: Refuses or is not eligible for radical cystectomy (RC)
Disqualifiers
Concurrent extra-vesical (that is, urethra, ureter, renal pelvis) transitional cell carcinoma of the urothelium
Prior treatment with an pan-fibroblast growth factor receptor (FGFR) inhibitor
Received pelvic radiotherapy <=6 months prior to the planned start of study treatment. If received pelvic radiotherapy greater than (>)6 months prior to the start of study treatment, there must be no cystoscopic evidence of radiation cystitis
Presence of any bladder or urethral anatomic feature that in the opinion of the investigator may prevent the safe use of Erdafitinib intravesical delivery system
