Clinical Trial Summary

In this study, the investigational drug, temsirolimus, will be combined with cetuximab, a biologic agent used in the treatment of colorectal cancer. Cetuximab in combination with temsirolimus may be more effective in treating advanced colorectal cancer than cetuximab alone. The purpose of this research study is to try to define the highest dose of cetuximab that can be used safely in combination with temsirolimus to treat advanced colorectal cancer that has progressed through standard therapy.

Description:

- Because this is a study to determine the highest dose of cetuximab that can be safely given with temsirolimus, groups of 3 participants will be treated at gradually increasing doses of cetuximab. Each group of 3 participants must complete 4 weeks (1 cycle) of treatment before the following group of 3 participants can start treatment at the higher dose. - Cetuximab is administered intravenously 7 days before the treatment cycle begins. Participants will receive a cetuximab infusion every week of the treatment cycle (days 1, 8, 15, 22) along with temsirolimus. Temsirolimus is also given intravenously. - As a precaution, participants will be pre-medicated with Benadryl/diphenhydramine to help prevent an allergic reaction. - During the study participants will have weekly clinical visits. Each clinic visit will last approximately 2-3 hours. During the clinic visit, the following tests and procedures will be performed: Physical exam; vital signs; and blood tests. A CT scan will be performed after every 2 cycles (8 weeks). - Pharmacokinetic (PK) blood samples will be taken at various points during the study. For each PK sample, we will take about 1 teaspoon of blood. There will be a total of 22 tubes of blood taken for the PK study.

Intervention

Drug:
• Temsirolimus
Given intravenously every week of each 28-day cycle (days 1, 7, 15, 22). Participants can continue to receive study treatment as long at their tumor is responding.
• Cetuximab
One dose is given intravenously 7 days prior to the start of each 28-day cycle, then it is given every week (along with temsirolimus)of each 28-day cycle (on days 1, 7, 15, 22). Participants can continue to receive study treatment as long at their tumor is responding.
