Primary Outcome Measures:
  • Adverse events, laboratory safety tests, dose-limiting toxicity [ Time Frame: CBC/chemistry: predose, Days 1-3, 7, 14, 21, & 28, Week 12. ]
  • Adverse events, laboratory safety tests, dose-limiting toxicity [ Time Frame: Additional hematology on Days 4, 5, & 6. ]
  • Adverse events, laboratory safety tests, dose-limiting toxicity [ Time Frame: AEs: Duration of study; up to 3 years postdose for serious events. ]
  • Adverse events, laboratory safety tests, dose-limiting toxicity [ Time Frame: ECG and VS - predose and selected postdose time points. ]

Secondary Outcome Measures:
  • Timed urine collections for IFNα2b excretion & IP-10. [ Time Frame: Days 1-7, 10, 14, 21, & 28/29. ]
  • Urine samples for SCH 721015 DNA content. [ Time Frame: Predose, Days 1-7 & 14. ]
  • Blood samples for SCH 721015 DNA; SCH 209702, & IFNα2b levels; antiadenoviral & anti-IFNα2b antibodies [ Time Frame: Pre- & postdose for SCH 721015 DNA; SCH 721015, & IFNα2b levels; & postdose for antibodies. ]
  • Urine cytology & FISH [ Time Frame: Days 1, 30 & 90 ]
  • Cystoscopy & bladder biopsies [ Time Frame: Screening & Day 90 ]

Enrollment: 17
Study Start Date: September 2006
Study Completion Date: August 2009
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SCH 721015 with SCH 209702 Genetic: SCH 721015 with SCH 209702
Each subject receives a single intravesical administration of SCH 721015 with SCH 209702 at dose levels of 1 x 10^9 to 3 x 10^11 particles/mL (based on assessment of tolerability, intermediate dose levels may be used).

Detailed Description:
A nonrandomized, open-label, rising-dose, parallel-group, multi-center study of SCH 721015 in patients with papillary bladder cancer, or carcinoma in situ that is refractory to Bacillus Calmette-Guerin. Subjects will receive a single intravesical administration of SCH 721015 with SCH 209702 in a total volume of 75 mL with a 1-hour dwell time. Subjects who at 3 months post administration demonstrate a complete response (CR on cystoscopy/biopsy and cytology) and who did not experience dose-limiting toxicity will be allowed to receive a second intravesical administration at the same dose level.
  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Histologically proven recurrent transitional cell carcinoma of the bladder, Stage Tis, Ta.
  • Patients with recurrent T1 disease who do not wish to have cystectomy.
  • Subjects must have failed at least two prior courses of BCG with or without recombinant interferon alpha administration.
  • At least 3 months must have passed since last intravesical treatment for bladder carcinoma.
  • Subjects must be 18 years of age or older.
  • Life expectancy of at least 3 months.
  • Adequate performance status (Karnofsky score >=70%).
  • Adequate laboratory values.

Exclusion Criteria:

    • Poorly controlled diabetes mellitus (HbA1C >10.0%);
    • Unstable chronic pulmonary disease requiring hospitalization or emergency room visit within the last 3 months;
    • Immunologically mediated disease (eg, rheumatoid arthritis, autoimmune hepatitis, immune mediated glomerulonephritis).
  • History of any clinically significant local or systemic infectious disease within 4 weeks prior to initial treatment administration.
  • Untreated bladder infection.
  • Positive for hepatitis BsAg or HIV Ab or hepatitis C.
  • Immunosuppressive therapy within the last 3 months.
  • BCG therapy or intravesical therapy within 3 months.
  • Traumatic catheterization within 1 month.
