Patients were randomized in a 2:1 ratio to receive either regorafenib plus BSC or placebo plus BSC to evaluate efficacy and safety. Treatment cycles consisted of 160 mg regorafenib (or matching placebo) once daily for three weeks on / one week off plus BSC. The primary endpoint was progression-free survival, and secondary endpoints included overall survival, time to progression, disease control rate, tumor response rate, and duration of response. The safety and tolerability of the two treatment groups were also compared.
Regorafenib is an investigational oral multi-kinase inhibitor and is currently being investigated in clinical trials for its potential to treat patients with various tumor types. Regorafenib is not approved by the FDA, the European Medicines Agency (EMA) or other health authorities.
