This study is for patients with metastatic adenocarcinoma arising from the colon or rectum who have received treatment(s) for metastatic disease with subsequent disease progression. Patients who are intolerant to treatment(s) are also included. This is a study for good performance status colorectal cancer patients who have exhausted standard therapy options.

Primary Outcome Measures:
  • To assess the best overall response rate per RECIST (BRR) in patients with metastatic adenocarcinoma of the colon or rectum treated with CP-675,206 . [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the safety and tolerability of CP-675,206 in this population. [ Time Frame: 18 mos ] [ Designated as safety issue: No ]
  • To identify any human anti human antibody (HAHA) response to CP-675,206 . [ Time Frame: 3 yrs ] [ Designated as safety issue: No ]
  • To identify potential relationships between polymorphisms in the Cytotoxic T lymphocyte-associated antigen 4 (CTLA4), Fcgamma receptor IIa (FcgRIIa), IgG2a genes with safety and/or immune response of patients treated with CP-675,206. [ Time Frame: 3 yrs ] [ Designated as safety issue: No ]
  • To assess additional evidence of anti-tumor activity as measured by duration of response, progression-free survival and overall survival. [ Time Frame: 2 yrs ] [ Designated as safety issue: No ]
  • To obtain pharmacokinetic (PK) data to be evaluated in a future meta analysis of CP-675,206 pharmacokinetics. [ Time Frame: 3 yrs ] [ Designated as safety issue: No ]
