NCT00880854
First received: April 13, 2009

  Purpose

The purpose of this study is to find out the highest safe dose of the investigational drug CP-675,206 when given in combination with BCG therapy to patients who have experienced recurrent superficial bladder cancer after standard BCG treatment.

In addition, the study will look to see if taking CP 675,206 generates an immune response and evaluate how the drug affects superficial bladder cancer.

Primary Outcome Measures:
  • To determine the safety of CP-675,206 when delivered in combination with BCG in patients with BCG-resistant bladder carcinoma in situ [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine whether patients treated with CP-675,206 in combination with BCG develop cancer antigen-specific systemic immune responses [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • To determine whether patients treated with CP-675,206 in combination with BCG develop an increase in tumor-infiltrating lymphocytes [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • To determine whether patients treated with CP-675,206 in combination with BCG develop pathological and cytological complete responses [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • To determine the 1-year recurrence-free survival [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • To determine a recommended dose and schedule for phase II trial evaluation based on the maximum tolerated dose [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
