Conditions: Colorectal Cancer
Keywords: Colorectal cancer KRAS wild type tumors
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 20
Healthy volunteers: no

Brief summary:
This study is being performed to test if the use of high dose of cetuximab in combination with irinotecan overcomes the resistance seen with standard dose of cetuximab plus irinotecan in patients with wild type KRS tumors that have advanced colon or rectal cancer

Detailed description:
Cetuximab is a manufactured antibody-antibodies are proteins that can be found circulating in your blood stream. The growth of colorectal cancer may be affected by the interaction of a growth factor known as "epidermal growth factor" (EGF) with its receptor.

Cetuximab is a antibody directed against the receptor for EGF and has been shown to turn off the activity of the receptor and to stop the growth of cancer cells in many laboratory tests. Cetuximab has been recently approved by the Food and Drug Administration in the treatment of patients with advanced colorectal cancer and who failed standard chemotherapy. Cetuximab has been shown to delay the progression of colorectal cancer when given alone in patients who have failed standard chemotherapy and when given with a chemotherapy drug called irinotecan in patients who have failed irinotecan.

Arms:
