Study Description

Brief Summary:
This is a Phase 3 multicenter, double-blind, randomized, placebo-controlled study to evaluate the efficacy of giving an oral targeted FGFR1-3 inhibitor, infigratinib, as adjuvant treatment following surgery in adult subjects with invasive urothelial carcinoma and susceptible FGFR3 genetic alterations (mutations, and gene fusions or translocations [ie, rearrangements) who have disease that is considered at high risk for recurrence with surgery alone. The study enrolls subjects with either bladder cancer post radical cystectomy or upper tract urothelial cancer post distal ureterectomy and/or nephrectomy. Study treatment is randomized between infigratinib or placebo with treatment until invasive local or distal disease recurrence.

Arm Intervention/treatment
Experimental: Infigratinib 125 mg
Participants will be randomly assigned (1:1) to receive oral infigratinib administered once daily for the first 3 weeks (21 days) of each 28-day cycle for a maximum of 52 weeks
 Drug: Infigratinib
Participants randomly assigned to infigratinib will receive hard gelatin capsules for oral administration of infigratinib 125 mg once a day (administered as one 100-mg capsule and one 25-mg capsule) using a 3 weeks on (Days 1-21) /1 week off (Days 22-28) dosing schedule.
Other Names:
  • IP
  • Study drug
Placebo Comparator: Placebo
Participants will be randomly assigned (1:1) to receive oral placebo administered once daily for the first 3 weeks (21 days) of each 28-day cycle for a maximum of 52 weeks
 Drug: Placebo
Participants randomly assigned to placebo will receive placebo matching in appearance the investigational product (infigratinib), which will be provided as hard gelatin capsules for oral use and will be administered once daily on a 3 weeks on (Days 1-21) /1 week off (Days 22-28) dosing schedule.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Centrally determine disease-free survival (DFS) [ Time Frame: Randomization through 1 year after end of treatment ]

Secondary Outcome Measures :
  1. Compare DFS including intraluminal low-risk recurrence [ Time Frame: Randomization through up to an approximated 5 years (60 months) after end of treatment ]
  2. Compare metastasis-free survival (MFS) [ Time Frame: Randomization through 1 year after end of treatment ]
  3. Compare overall survival (OS) [ Time Frame: Randomization through 1 year after end of treatment ]
  4. Compare investigator-reviewed DFS [ Time Frame: Randomization through 1 year after end of treatment ]
  5. Number of participants with adverse events (AEs) and serious adverse events (SAEs) as a measure of safety and tolerability [ Time Frame: 30-Day Post-Treatment ]

Criteria

Inclusion Criteria

  1. Have histologically or cytologically confirmed, invasive urothelial carcinoma with susceptible FGFR3 alterations within 120 days following nephroureterectomy, distal ureterectomy, or cystectomy
  2. If the patient received neoadjuvant chemotherapy, pathologic stage at surgical resection must be AJCC Stage ≥ ypT2 and/or yN+.

  3. If the patient did not receive neoadjuvant chemotherapy:

    1. Must be ineligible to receive cisplatin-based adjuvant chemotherapy per the Galsky criteria:

      • creatinine clearance < 60cc/min or
      • ≥ Grade 2 hearing loss or
      • ≥ Grade 2 neuropathy)
    2. Pathologic stage must be AJCC Stage ≥pT2 pN0-2 M0 (post-lymphadenectomy or no lymphadenectomy [pNx]) for upper tract disease.
    3. Pathologic stage should be AJCC Stage ≥pT3 or pN+ (bladder cancer).
  4. Have Eastern Cooperative Oncology Group (ECOG) performance status of ≤2.
  5. Patients must have no evidence of metastatic disease based on screening CT or MRI.

Exclusion Criteria:

  1. Presence of positive surgical margins following nephroureterectomy, distal ureterectomy, or cystectomy.
  2. Have received Bacillus Calmette-Guerin (BCG) or other intravesical therapy for Non-Muscle Invasive Bladder Cancer (NMIBC) within the previous 30 days.
  3. Have previously or currently is receiving treatment with a mitogen-activated protein kinase (MEK) or selective FGFR inhibitor.
  4. Have impaired gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral infigratinib (eg, active ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection)
  5. Have current evidence of corneal or retinal disorder/keratopathy.
  6. Have a history and/or current evidence of extensive tissue calcification.
  7. Have current evidence of endocrine alterations of calcium/phosphate homeostasis (eg, parathyroid disorders, history of parathyroidectomy, tumor lysis, tumoral calcinosis), unless well controlled.
  8. Are currently receiving or are planning to receive during participation in this study, treatment with agents that are known strong inducers or inhibitors of CYP3A4 and medications which increase serum phosphorus and/or calcium concentration.
  9. Clinically significant cardiac disease.
  10. Recent (< 3 months prior to first dose of study drug) transient ischemic attack or stroke.
