Answer

Regorafenib, a kinase inhibitor, was approved in September 2012. It is indicated for patients with metastatic colorectal cancer who have been previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy; anti-VEGF therapy (eg, bevacizumab, ziv-aflibercept); and, if KRAS wild type, anti-EGFR therapy (eg, cetuximab, panitumumab). [124]

Approval was based on a multicenter trial (n=760) that randomized patients at a 2:1 ratio to receive regorafenib in addition to best supportive care or placebo plus best supportive care. Statistically significant benefit in OS and PFS was observed for regorafenib over placebo in patients with metastatic colon cancer in whom all approved standard therapies had failed. [125]
