Brief summary:
Research Hypothesis: Subjects in the study population who are treated with cetuximab in combination with irinotecan will have higher response rates than subjects treated with irinotecan alone.

Detailed description:
Primary Objective:

·The primary aim of this study is to assess the response rate of patients with previously treated colorectal cancer (CRC) Number of Subjects: 31

Study Population:

Subjects with metastatic, CRC who have failed a first-line chemotherapeutic regimen containing oxaliplatin and a fluoropyrimidine, and who have not previously received irinotecan or cetuximab for treatment of CRC.

Test Product, Dose and Mode of Administration, Duration of Treatment:

Cetuximab administered at an initial dose of 500 mg/m2 intravenously (IV) over 120 minutes, followed by 500 mg/m2 every 2 weeks IV over 60 minutes.

Reference Therapy, Dose and Mode of Administration, Duration of Treatment: Irinotecan administered at a dose of 150a or 180 mg/m2 IV over 60 minutes every two weeks.

Arms:
arm 1: Cetuximab will be administered at the dose of 500 mg/m2 intravenously (IV) over 120 minutes, followed by 500 mg/m2 every 2 weeks, IV over 2 hours at an infusion rate not to exceed 5 ml/min. Followed immediately by Irinotecan administered at a dose of 180 mg/m2 IV over 60 minutes every two weeks.

Interventions: intervention 1: Cetuximab intervention 2: Irinotecan
Intervention descriptions: intervention 1: The treatment will include cetuximab 500 mg/m² IV for 120 minutes followed by irinotecan 180 mg/m² or 60 minutes. The starting dose of irinotecan for patients who are 70 years old or greater, or who have had radiation therapy to the abdomen or pelvis, or whose level of functioning is poor (performance status of 2) will have a starting dose of 150 mg/m2 for irinotecan. All subsequent treatments will include cetuximab 500 mg/m² IV over 60 minutes and irinotecan 150 mg/m² or 180 mg/m2 intravenously over 60 minutes every 2 weeks. intervention 2: The treatment will include cetuximab 500 mg/m² IV for 120 minutes followed by irinotecan 180 mg/m² or 60 minutes. The starting dose of irinotecan for patients who are 70 years old or greater, or who have had radiation therapy to the abdomen or pelvis, or whose level of functioning is poor (performance status of 2) will have a starting dose of 150 mg/m2 for irinotecan. All subsequent treatments will include cetuximab 500 mg/m² IV over 60 minutes and irinotecan 150 mg/m² or 180 mg/m2 intravenously over 60 minutes every 2 weeks.
