Descriptive Information
Brief Title  ICMJE Lapatinib and Cetuximab in Patients With Solid Tumors
Official Title  ICMJE A Phase I Study of Lapatinib and Cetuximab in Patients With Solid Tumors
Brief Summary

This trial is for patients with colon cancer, head and neck cancer and lung cancer that has not responded to standard therapy.

Cetuximab targets a receptor on cancer cells called the Epidermal Growth Factor Receptor or EGFR. It is thought that this receptor is turned "on" in some cancers, enabling cancer cells to divide and grow. Blocking this receptor can turn this signal off. Cetuximab blocks this receptor from the outside of cancer cells. It is thought that cancer cells can turn this signal back on by the EGFR joining with a related receptor called ErbB2. Lapatinib blocks both EGFR and ErbB2 from the inside of cancer cells. In laboratory experiments it has been found that combining drugs that target both EGFR and ErbB2 might work better in turning this signal back off. The purpose of this study is to determine the maximum dosages that patients can tolerate when these two medicines are given at the same time.

In addition, in order to be on this trial, patients must agree to have a tumor biopsy before starting treatment on this study and 21 days after starting treatment. These biopsies are a required part of the study. Patients must also agree to have blood drawn for research testing to see whether genetic differences between patients explain different reactions to and side effects from, these medicines.
