  Purpose

A majority of patients with bladder cancer have disease confined to the inner lining of the bladder. Patients with high risk features (high grade tumors, tumors invading into a deeper superficial layer) are routinely treated with Bacillus Calmette Guerin (BCG) instilled in their bladder after the tumor has been removed. While up to 55% of patients respond to BCG, failure to respond may suggest a more aggressive tumor that requires more definitive therapy with complete bladder removal. BCG is believed to work by stimulating the body's own immune system to attack tumor cells. It may also work by blocking the machinery that tumors use to grow blood vessels which fuel tumor growth. A newer oral drug, sunitinib has shown to help patients with metastatic bladder cancer by blocking new blood vessel growth (VEGF inhibition). The investigators are studying the use of BCG followed by sunitinib in patients with high risk non-muscle invasive bladder cancer to evaluate the complete response (no visible evidence of tumor in the bladder) at 3 months and 6 months. The investigators will also evaluate whether there is recurrent tumor at three years.

Intervention Details:
    Drug: Sunitinib

    Patients are treated with a 6-week induction course of intravesical bacillus Calmette-Guerin (BCG) followed by a 2 week rest period and 4 week course of oral Sunitinib.

    Patients will receive intravesical BCG (81 mg Theracys BCG in 50 ml normal saline) once weekly for 6 weeks within 6 weeks of bladder biopsy confirming high risk non-muscle invasive urothelial carcinoma. Two weeks after completion of BCG, patients will receive Sunitinib (50 mg daily) continuously for 28 days followed by a two week rest period. Patients will be reassessed with transurethral resection and urine cytology. Those with residual/recurrent disease will receive a second course identical to the initial protocol. Those with a complete response following initial or second treatment will be placed on maintenance BCG (3 week course every 6 months for 2 years). Those failing (progression, intolerance) initial/secondary treatments will be offered alternative therapy.

    Other Name: Sutent
Detailed Description:

Despite a complete response of 45-55% in patients with non-muscle invasive urothelial carcinoma involving the lower urinary tract at 3 months, many patients suffer from multiple recurrences and progression in up to 1/3 of patients. While radical cystectomy is an effective local therapy for patients with high risk non-invasive disease, roughly 15% of patients will still develop progression. More importantly, the morbidity of radical cystectomy as described above represents a barrier to treatment in some individuals. Thus, there is a real need to identify newer therapies that reduce morbidity and improve outcomes in patients with non-invasive urothelial cancer. While multiple drug regimens have been the standard for many forms of cancer including invasive bladder cancer, few reports exist on multidrug regimens for non-invasive bladder cancer.

The fundamentally agreed upon mechanism of action of BCG intravesical therapy for superficial bladder cancer is the generation of a non-specific immune response with the expression of cytokines by inflammatory cells resulting in tumor death. Cytokines produced by BCG therapy such as IFNα may block vascular endothelial growth factor (VEGF) which is expressed in superficial and invasive bladder cancer and may provide a mechanism for disease progression.

Sunitinib is an oral tyrosine kinase inhibitor that blocks VEGF. Recent reports demonstrate clinical response in patients with metastatic bladder cancer treated with sunitinib after recurrence following standard chemotherapeutic regimens. The addition of sunitinib following BCG in order to consolidate VEGF inhibition may result in superior 3 month complete response rates. We know that patients who have a complete response to BCG at 3 months have improved disease.

  • Tumor stage less than or equal to T1 confirmed by pathology report
  • Patients with a T1 tumor will require a restaging TURBT confirming no higher stage tumor prior to study enrollment

  • Patients must have adequate organ and marrow function as defined below:

    • absolute neutrophil count > 1,500/mcL
    • platelets > 100,000/mcL

Exclusion Criteria:

  • Patients with a prior history of radiation for bladder cancer
  • Patients with a prior history of radiation for prostate cancer are eligible for the study
  • Greater than or equal to T2N0M0 transitional cell carcinoma of the bladder on current pathology or in the past
  • Patients with a prior history of upper tract urothelial carcinoma are eligible for participation in the study as long as there is no evidence of disease for 6 months prior to study enrollment
  • Patients with other malignancies are eligible for enrollment in the study but should not be on active treatment for this malignancy within 12 months of study enrollment. Patients with prior history of local treatment for prostate cancer are eligible for participation in the study

  • The definition of effective contraception will be based on the judgment of the principal investigator or a designated associate.
  • Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into this study.
