BRAFV600E is the driver mutation for approximately 10% of colorectal cancers and is found more
often in right-sided disease and older patients.

The presence of this mutation is associated with a poor prognosis and resistance
to chemotherapy, especially in the metastatic setting.

Standard first line therapy in these patients has a significantly shorter overall
survival compared to patients with BRAF wild-type disease.

Historically, subsequent lines of chemotherapy have shown limited efficacy with median
progression free survival (PFS) of 2 to 3 months and overall survival (OS) of around
4 to 6 months.

The addition of an EGFR tyrosine kinase inhibitor to the therapeutic regimen did not have any benefit in
PFS or OS.
