* Serum creatinine ≤ 1.5 x ULN or serum creatinine \> 1.5 - 3 x ULN if calculated creatinine clearance (CrCl) is ≥ 30 mL/min using the Cockcroft-Gault equation

Cardiovascular:

No impaired cardiac function or clinically significant cardiac diseases, including any of the following:

* History or presence of serious uncontrolled ventricular arrhythmias

* Clinically significant resting bradycardia

* LVEF assessed by 2-D echocardiogram (ECHO) \< 50% or lower limit of normal (whichever is higher) or multiple gated acquisition scan (MUGA), \< 45% or lower limit of normal (whichever is higher)

* Myocardial Infarction (MI), severe/unstable angina, Coronary Artery Bypass Graft (CABG), Congestive Heart Failure (CHF), Cerebrovascular Accident (CVA), Transient Ischemic Attack (TIA), Pulmonary Embolism (PE)within 6 months prior to starting study drug

Inclusion Criteria
  • Histologically confirmed early stage urothelial carcinoma of the bladder defined as Ta, T1, or Tis stage.
  • Presence of either an FGFR3 mutation or FGFR3 over-expression within bladder tumor tissue.
  • Documented BCG-refractory disease defined as failure to achieve a tumor free state after at least 2 prior induction courses of intravesical BCG therapy.
  • Medically unfit to undergo cystectomy or electively choosing to forego cystectomy
  • Patients who give a written informed consent obtained according to local guidelines
Exclusion Criteria
  • Patients with muscle-invasive (i.e. T2, T3, T4), locally advanced non-resectable, or metastatic urothelial carcinoma as assessed on baseline radiographic imaging obtained within 28 days prior to study registration.
  • Patients with concurrent upper urinary tract (i.e. ureter, renal pelvis) non-invasive urothelial carcinoma.
  • Patients with another primary malignancy within 3 years prior to starting study drug, with the exception of adequately treated in-situ carcinoma of the uterine cervix, clinically localized prostate cancer, biochemically relapsed non-metastatic prostate cancer (i.e., PSA only disease), or skin cancer (such as basal cell carcinoma, squamous cell carcinoma, or non-melanomatous skin cancer)
  • Patients who have received the last administration of an anti-cancer therapy including chemotherapy, immunotherapy, and monoclonal antibodies ≤ 4 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy
  • Patients who have received prior VEGFR-targeted or FGFR-targeted agents (i.e., sunitinib, pazopanib, sorafenib, bevacizumab, axitinib, etc.).
  • Patients who have had radiotherapy ≤ 4 weeks prior to starting study drug, or who have not recovered from radiotherapy toxicities
  • Patients who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury ≤ 4 weeks prior to starting study drug, or patients who have had minor procedures (i.e., TURBT), percutaneous biopsies or placement of vascular access device ≤ 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury
  • Uncontrolled hypertension defined by a systolic blood pressure (SBP) ≥ 160 mm Hg and/or d iastolic blood pressure (DBP) ≥ 100 mm Hg, with or without anti-hypertensive medication(s)
  • Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of dovitinib (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
  • Cirrhosis, chronic active hepatitis or chronic persistent hepatitis
  • Known diagnosis of human immunodeficiency virus (HIV) infection (HIV testing is not mandatory)
  • Patients who are currently receiving anti-coagulation treatment with therapeutic doses of warfarin. Full-dose anti-coagulation with low molecular weight heparin is permitted.
  • Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g., active or uncontrolled infection, uncontrolled diabetes) that could cause unacceptable safety risks or compromise compliance with the protocol
  • Pregnant or breast-feeding women
  • Women of child-bearing potential, who are biologically able to conceive, not employing two forms of highly effective contraception. Highly effective contraception must be used throughout the trial and up to 8 weeks after the last dose of study drug (e.g. male condom with spermicidal; diaphragm with spermicide; intra-uterine device). Oral, implantable, or injectable contraceptives that may be affected by cytochrome P450 interactions are not considered effective for this study. Women of child-bearing potential, defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months), must have a negative serum pregnancy test ≤ 14 days prior to starting study drug.
  • Fertile males not willing to use contraception, as stated above
  • Patients unwilling or unable to comply with the protocol

Primary Outcome Measures
NameTimeMethod
Determine 6-Month Complete Response Rate6 months

The 6-month complete response rate is defined as the proportion of patients treated with dovitinib with no evidence of any remaining urothelial carcinoma tumors of any T-stage (including Tis) present within the bladder as assessed by standard of care cystoscopic examination with transurethral resection of bladder tumor (TURBT) and urine cytology performed at 6 months after initiation of study therapy.

Secondary Outcome Measures
NameTimeMethod
Determine 1-Year Relapse-Free Survival Rate12 months

The 1-year relapse free survival rate is defined as the proportion of patients treated with dovitinib with no evidence of any remaining urothelial carcinoma tumors at 12 months of follow-up.

Determine Rate of Progression to Muscle-Invasive Stage12 months

The rate of progression to muscle-invasive stage for dovitinib is defined as the proportion of patients with clinical or pathologic progression to muscle-invasive stages (i.e., T2-T4) at any time point on study.

Determine 3-Month and 6-Month Partial Response Rates6 months

The 3- and 6-month partial response rates are defined as the proportion of patients treated with persistent but reduced T-stage tumors on post-therapy TURBT (i.e., T1 ≥ Ta; T1+Tis ≥ T1).

Characterize Treatment-related Toxicity Rates12 months

Treatment-related toxicity rates will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) v4.0. All grade 3-4 adverse events and other adverse events occurring in more than 20% of patients are reported.
