Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase 2 study (the second phase in testing a new drug or drug combination) to see how useful the combination of two drugs, panitumumab and trametinib, are in patients with advanced colorectal cancer with KRAS, NRAS, or BRAF wild type (genes that are not mutated).

Panitumumab is a drug that is approved by Health Canada for the treatment of advanced colorectal cancer with KRAS wild type. Panitumumab works by binding to and blocking the protein, epidermal growth factor receptor (EGFR) from working.

Trametinib is a drug that is approved by Health Canada for the treatment of melanoma with a mutation in the BRAF gene. Trametinib works by binding to and blocking mitogen-activated protein kinase kinase (MEK) 1 and MEK2 from working.

Previous studies have shown that the combination of panitumumab and trametinib may be more useful in KRAS, NRAS, or BRAF wild type colorectal cancer.
