|Official Title:||A Phase 2, Two-arm Multicenter, Open-Label Study to Determine the Efficacy and the Safety of Two Different Dose Regimens of a Pan-FGFR Tyrosine Kinase Inhibitor JNJ-42756493 in Subjects With Metastatic or Surgically Unresectable Urothelial Cancer With FGFR Genomic Alterations|
|Actual Study Start Date :||April 22, 2015|
|Actual Primary Completion Date :||September 15, 2022|
|Estimated Study Completion Date :||December 29, 2023|
Experimental: Erdafitinib (8 milligram)
Prior to interim analysis 1 (IA1), there were 2 treatment regimens: Regimen 1 (10 milligram [mg] once daily, 7 days on/7 days off); and Regimen 2 (6 mg once daily for 28 days). Following IA1, Regimen 1 is closed for further enrollment and starting dose of Regimen 2 is increased to 8 mg once daily for 28 days on a 28-day cycle (referred to as Regimen 3). Participants who enrolled in DDI substudy will receive pretreatment with single doses of midazolam (Day -2) and metformin (Day -1). Participants enrolled in DDI substudy will receive 8 mg erdafitinib treatment from Day 1 to Day 15, single doses of midazolam 2.5 mg (Day 13) and metformin 1000 mg (Day 14) and erdafitinib treatment will continued until disease progression. Participants who completed the DDI substudy and continue to benefit from erdafitinib treatment, will continue to receive erdafitinib in long-term extension (LTE) phase.
8 mg orally once daily for 28 days on a 28 day cycle.
Other Name: JNJ-42756493
Participants who enrolled in DDI substudy will receive pretreatment with single dose of midazolam on Day -2 and single dose of midazolam on Day 13.
Participants who enrolled in DDI substudy will receive pretreatment with single dose of metformin on Day -1 and single dose of metformin on Day 14.
- Percentage of Participants with Best Overall Response [ Time Frame: From the start of the study treatment until the end of treatment (1 year) ]The objective response rate is defined as the percentage of participants with measurable lesions achieving a Complete Response (CR) or Partial Response (PR) based on Response Evaluation Criteria In Solid Tumors Version 1.1(RECIST v1.1) criteria. Per RECIST v1.1) for target lesions and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), greater than or equal to (>=) 30 percent (%) decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
- Progression-free survival [ Time Frame: From the date of the first dose of study drug until disease progression or death as assessed up to the last efficacy assessment for disease progression (up to 5 years) ]Progression-free survival is defined as the duration from the date of the first dose of study drug until the date of first documented evidence of progressive disease (or relapse for participants who experience a complete response during the study) or death, whichever comes first.
- Duration of Response [ Time Frame: From the date of the first dose of study drug until disease progression or death as assessed up to the last efficacy assessment for disease progression (up to 5 years) ]The duration of response (CR or PR) is defined as the earliest date a participant achieved a complete response (CR) or a partial response (PR), calculated from the date of initial documentation of a response to the date of first documented evidence of progressive disease (or relapse for participants who experience CR during the study) or death.
- Overall survival [ Time Frame: From the date of the first dose of study drug until death (up to 5 years) ]Overall survival is defined as the time interval in days between the date of the first dose of study drug and the participant's death from any cause. If the participant is alive or the vital status is unknown, the participant's data will be censored at the date the participant was last known to be alive.
- Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Screening up to end of study (up to 5 years) ]An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. An SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above.
- Percentage of Participants With Biomarker Assessment [ Time Frame: Baseline up to end of study (up to 5 years) ]Presence of circulating biomarkers (DNA, RNA, or proteins) associated with FGFR aberrations will be observed.
- Plasma Concentration of Erdafitinib [ Time Frame: Baseline up to end of study (up to 5 years) ]
- Plasma Clearance of Erdafitinib [ Time Frame: Baseline up to end of study (up to 5 years) ]
- Volume of Distribution of Erdafitinib [ Time Frame: Baseline up to end of study (up to 5 years) ]
- Plasma Concentration of Midazolam and its Metabolite (1-OH-midazolam) [ Time Frame: Up to 14 days ]
- Plasma Concentration of Metformin [ Time Frame: Up to 15 days ]

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Must have histologic demonstration of metastatic or surgically unresectable urothelial cancer. Minor components of variant histology such as glandular or squamous differentiation, or evolution to more aggressive phenotypes such as sarcomatoid or micropapillary change are acceptable
- Must have measurable disease according to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) at baseline
- Must have an Eastern Cooperative Oncology Group (ECOG) performance status score 0, 1, or 2
- Must have adequate bone marrow, liver, and renal function as described in protocol
- Negative pregnancy test (urine or serum beta human chorionic gonadotropin [b-hCG]) at Screening for women of child bearing potential who are sexually active
- Must have shown disease progression according to RECIST, version 1.1, following prior chemotherapy for metastatic or surgically unresectable urothelial cancer. Participants who received neoadjuvant or adjuvant chemotherapy and showed disease recurrence or progression according to RECIST, version 1.1, within 12 months of the last dose are considered to have received chemotherapy in the metastatic setting. These participants will be referred to as chemo-refractory participants. (Participants who have shown disease progression according to RECIST, version 1.1 following prior treatment with anti-Programmed death-ligand 1 (anti PDL1/PD1) antibodies are also eligible) For DDI substudy
- Disease progression following prior chemotherapy for metastatic or surgically unresectable urothelial cancer. Participants who received neoadjuvant or adjuvant chemotherapy and showed disease recurrence or progression within 12 months of the last dose are considered to have received chemotherapy in the metastatic setting
- Received chemotherapy, targeted therapies, definitive radiotherapy, or treatment with an investigational anticancer agent within 2 weeks (in the case of nitrosoureas and mitomycin C, within 6 weeks; in the case of immunotherapy, within 4 weeks) before the first administration of study drug. Localized palliative radiation therapy (but should not include radiation to target lesions) and ongoing bisphosphonates and denosumab, are permitted
- Has persistent phosphate level greater than upper limit of normal (ULN) during screening (within 14 days of treatment and prior to Cycle 1 Day 1) and despite medical management
- Has a history of or current uncontrolled cardiovascular disease
- Females who are pregnant, breast-feeding, or planning to become pregnant within 3 months after the last dose of study drug and males ho plan to father a child while enrolled in this study or within 5 months after the last dose of study drug
- Has not recovered from reversible toxicity of prior anticancer therapy (except toxicities which are not clinically significant such as alopecia, skin discoloration, or Grade 1 neuropathy)
