Primary Outcome Measures:
  • The safety and tolerability of the maximum tolerated dose defined as a dose regimen where no more than 1 of 6 subjects experiences a dose limiting toxicity. [ Time Frame: End of 2009 ]

Secondary Outcome Measures:
  • pharmacokinetics disease assessment [ Time Frame: 2010 ]
  • Clearance of irinotecan (if data permit) and AUC, Cmax, tmax, and t1/2 of irinotecan and SN-38 after administration of irinotecan plus cetuximab. [ Time Frame: 2010 ]
  • AUC(0-24), Cmax, tmax, and t1/2 of pazopanib when administered with irinotecan and cetuximab [ Time Frame: 2010 ]
  • AUC(0-24), Cmax, and tmax of cetuximab when administered with irinotecan alone [ Time Frame: 2010 ]
  • AUC(0-24), Cmax, and tmax of cetuximab when administered with irinotecan plus pazopanib. [ Time Frame: 2010 ]
  • The ratio of SN-38 AUC(0-24) and irinotecan AUC(0-24) on Cycle 1 Day 1 and on Cycle 2 Day 1. [ Time Frame: 2010 ]
  • Objective response rate (complete response (CR) plus partial response (PR)) will be the primary measure of antitumor activity [ Time Frame: 2010 ]
  • Stable disease (SD) at 4 months [ Time Frame: 4 months ]
  • Time to progression

NOTE: Computed tomography or magnetic resonance imaging (MRI) scans are not required to rule out central nervous system metastases unless the subject is exhibiting neurologic signs or symptoms. If, however, CT or MRI scans are performed and document central nervous system disease, the subject is ineligible, regardless of whether neurologic signs or symptoms are present.
  • Any serious and/or unstable pre-existing medical, psychiatric, or other condition (including laboratory abnormalities) that could interfere with subject safety or obtaining informed consent.
