Brief summary
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.
Detailed description
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.
Interventions
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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cohort 1: Recurrence-Free Survival (RFS) | From randomization (Cycle 1 Day 1, pre-dose) up to 48.2 months | RFS was defined as the time from the date of randomization until the date of the reappearance of high-risk disease (high-grade Ta, T1 or carcinoma in situ \[CIS\]), or death, whichever was reported first. Recurrence was assessed using cystoscopy, bladder mapping, urine cytology, and computed tomography (CT)/ magnetic resonance imaging (MRI) urogram. Participants who were recurrence-free and alive or had unknown status were censored at the last tumor assessment. The Kaplan-Meier method was used to estimate the distribution of overall RFS for each treatment group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cohort 1: Recurrence-Free Survival Rate at 6 Months and 12 Months | At Month 6 and Month 12 | RFS rate was the proportion of participants who were recurrence-free and alive based on Kaplan-Meier estimates. RFS was defined as the time from the date of randomization until the date of the reappearance of high-risk disease (high-grade Ta, T1 or CIS), or death, whichever was reported first. Recurrence was assessed using cystoscopy, bladder mapping, urine cytology, and CT/ MRI urogram. Participants who were recurrence-free and alive or had unknown status were censored at the last tumor assessment. |
| Cohort 1: Time to Progression | From randomization (Cycle 1 Day 1, pre-dose) up to 48.2 months | Time to progression (TTP) was defined as the time from the date of randomization until the date of first documented evidence of any of the following: disease progression (PD) or death. PD included development of or increase in stage to lamina propria invasion (for example- increase from Ta to T1), development of or increase in stage to muscle-invasive disease (stage greater than or equal to \[\>=\] T2), development of or increase in stage to lymph node (N+) or distant metastasis (M1) disease (participants must have previously been diagnosed with N0 and/or M0 disease), increase in tumor grade from low to high (including CIS). |
| Cohort 1: Overall Survival | From randomization (Cycle 1 Day 1, pre-dose) up to 48.2 months | Overall survival was defined as the time from the date of randomization to the date of the participant's death due to any cause. |
| Number of Participants With Treatment-emergent Adverse Events (TEAEs) | From start of treatment (Day 1) up to 25.2 months | An adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. TEAEs were the events between first dose of study drug and up to 30 (+7 days) days after last dose or before start of subsequent anticancer therapy, whichever occurred first. All TEAEs including serious and non-serious events were reported in this outcome measure (OM). |
| Plasma Concentrations of Erdafitinib | All cohorts: Pre-dose on Cycle 1 Day 14, pre-dose and 3 hours post-dose on Cycle 2 Day 1 (each cycle was of 28 days) | Plasma concentrations of erdafitinib were reported. Plasma samples were analyzed using liquid chromatography/mass spectrometry method. |
