This research study is studying the safety, tolerability, and tumor activity of the study drug known as rogaratinib as a possible treatment for bladder cancer.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has not approved rogaratinib as a treatment for any disease.

In this research study, the investigators are studying rogaratinib in bladder cancer that has not responded to BCG and overexpresses a protein called FGFR1 or 3.

• Mutations in FGFR help bladder cancer grow. In metastatic cancers that express FGFR 1 or 3, rogaratinib and other inhibitors of FGFR have shown to be an effective treatment
• Rogaratinib is an oral drug that inhibits FGFR
• To date, no therapy has been shown to be effective in controlling bladder cancer after BCG does not work.

Inclusion Criteria:

• Male or female patients ≥ 18 years of age (at least age of legal maturity)

• Have a histologically-confirmed diagnosis of high risk non-muscle-invasive (T1, High Grade Ta and/or CIS) transitional cell carcinoma of the bladder. Subjects with tumors of mixed transitional/non-transitional cell histology are not allowed.

• In subjects with Ta and T1, have undergone complete TURBT as characterized by:

  • Attainment of a visually complete resection
  • Residual CIS not amenable to complete transurethral resection is acceptable
  • The most recent cystoscopy / TURBT must have been performed within 8 weeks prior to the first dose of trial treatment

• Have been treated with adequate BCG therapy and have developed NMIBC that is unresponsive to BCG therapy. Adequate BCG therapy must include: An induction course with at least 5 instillations of BCG (adequate induction); and at least 7 instillations of BCG within 9 months of the first instillation of adequate induction therapy. BCG unresponsive high risk NMIBC is defined as: Stage progression at 3 months (±4 weeks) despite adequate induction therapy (e.g., Ta to T1, or CIS to T1; note: adequate induction therapy only, defined above, is required in this case); or Persistent high risk NMIBC at 6 months (±4 weeks) after adequate BCG therapy or Recurrent high risk NMIBC within 9 months of the last BCG instillation despite adequate BCG therapy.

• Have elected not to undergo, or are considered ineligible for radical cystectomy, as determined by the treating surgeon. Reasons for ineligibility or refusal of radical cystectomy should be discussed with the subject as part of the informed consent process and should be captured on the appropriate case report form. Ineligibility factors for radical cystectomy may include, but are not limited to:

  • Cardiovascular disease (e.g. recent acute coronary syndrome, arrhythmia, heart failure)
  • Chronic obstructive pulmonary disease that would preclude a safe surgical procedure, as determined by the treating surgeon
  • Poor performance status (e.g. ECOG >2)
  • Prior major abdominal and pelvic surgery, that would preclude a safe surgical procedure, as determined by the treating surgeon

• High FGFR 1/3 mRNA expression levels (RNAscope score of 3+ or 4+; measurement is part of the protocol) in archival or fresh tumor biopsy specimen

• Existence of archival or fresh tumor biopsy specimen for FGFR1/3 mRNA expression testing. Patients who don't have archival tissue specimens meeting eligibility requirements may undergo a biopsy. Acceptable samples include core needle biopsies for deep tumor tissue (minimum three cores) or excisional, incisional, punch, or forceps biopsies for cutaneous, subcutaneous, or mucosal lesions.

• Ability to understand and signing of the written patient information/informed consent form (PI/ICF) for FGFR testing

• Ability to understand and signing of the written PI/ICF for study treatment eligibility. Signed informed consent form must be available before any study-specific procedure for the respective study parts may begin.(PI/ICF for study treatment eligibility must be offered only after positive results in FGFR testing study received by site.)

• Eastern Cooperative Oncology Group performance status 0 or 1

• Adequate bone marrow, liver and renal function as assessed by laboratory requirements conducted within 14 days before registration:

  • Absolute neutrophil count (ANC) ≥ 1,500/mm3 (without granulocyte colony-stimulating factor support within 2 weeks before the first study drug administration)
  • Hemoglobin ≥ 10 g/dL (without transfusion or erythropoietin within 4 weeks before the first study drug administration)
  • Platelet count ≥ 100,000/mm3 (without transfusion within 2 weeks before the first study drug administration)
  • Total bilirubin ≤ 1.5 x the upper limit of normal (ULN). Total bilirubin ≤ 3 x ULN for patients with known Gilbert syndrome.
  • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN
  • Alkaline phosphatase ≤ 2.5 times ULN
  • Lipase and amylase ≤ 2 x ULN
  • Serum albumin ≥ 2.5 g/dl
  • Glomerular filtration rate (GFR) ≥ 40 mL/min/1.73 m2 according to the modification of diet in renal disease (MDRD) abbreviated formula.

Note: at the investigator's discretion, an estimated creatinine clearance result <60 mL/min/1.73m² may be verified by measurement of creatinine clearance based on 24-hour urine collection or using EDTA, inulin, GFR scan. INR ≤ 1.5 x ULN and PTT or activated PTT (aPTT) ≤ 1.5 x ULN. Patients being treated with anticoagulant, e.g. warfarin or heparin, will be allowed to participate provided no prior evidence of an underlying abnormality in these parameters exists and they are on a stable dose as defined by the local standard of care.

• Negative serum pregnancy test in women of childbearing potential (performed within 7 days before the first treatment). Negative results must be available before the first study drug administration. Females are considered of childbearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months.
• Women and men of reproductive potential must agree to use adequate contraception when sexually active. This applies for the time period between signing of the informed consent form and until at least 5 months after the last study drug administration. The definition of adequate contraception will be based on the judgment of the investigator and on local requirements. Acceptable methods of contraception include, but are not limited to, (i) condoms (male or female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device; (iv) hormone-based contraception.

• Arterial or venous thrombotic events or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 6 months before the first study drug administration.

• Those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.

• Concomitant therapy with the following medication is prohibited

  • Concomitant use of strong inhibitors of CYP3A4 and strong inducers of CYP3A4 are not permitted for 2 weeks prior to start of study treatment or during the study.
  • Concomitant use of moderate and weak CYP3A4 inducers should be avoided as clinically significant decrease in plasma concentrations of rogaratinib cannot be ruled out.
  • Concomitant use of herbal preparations containing CYP3A4 inducers (e.g. St John's Wort) are not permitted during the study.
  • Grapefruit and grapefruit juice (CYP3A4 inhibitor) consumption is not permitted during the study.
  • Therapies that are known to increase serum calcium or phosphate levels (i.e. antacids, phosphate-containing laxatives oral/rectal, potassium phosphate)
  • Patients may not receive other investigational treatment or other approved anti-tumor therapy while on this protocol (excluding anti-VEGF therapy for ophthalmologic disease).

• Concomitant therapies that should be avoided:

  • Narrow therapeutic index drugs that are CYP3A4, P-gp, and BCRP substrates (e.g. alfentanil, cyclosporine, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, and tacrolimus) should be avoided, because drug interactions caused by irreversible inhibition of CYP3A4, P-gp, and BCRP by rogaratinib cannot be ruled out.
  • Fluconazole is considered a moderate to strong inhibitor of CYP2C9 and should be avoided, if possible.
  • No results are available from human interaction studies between rogaratinib and other chemotherapies. No data are available to evaluate the interaction between rogaratinib and radiation. Therefore, when administering these agents after study drug has been withdrawn, it should be taken into consideration that rogaratinib plasma concentrations may be detectable for a few days (depending on half-life) and the physiologic consequences that could interact with chemotherapy and radiotherapy may last even longer following discontinuation of rogaratinib.
