Summary:

      The purpose of this study is to determine whether CPX-1 is effective in patients with
      advanced colorectal cancer who have already received chemotherapy that included the drug
      oxaliplatin or irinotecan. All patients will receive CPX-1 at a dose of 210 units/m2 over 90
      minutes every two weeks.
