Per the recommendation from an independent Data Monitoring Committee, the CORRECT study was unblinded in late 2011 following a pre-planned interim analysis that determined that the regorafenib arm showed significant improvement in overall survival; patients on the placebo arm were unblinded and offered treatment with regorafenib.
Bayer plans to submit regorafenib for marketing authorization in mCRC in 2012.
In 2011, Bayer and Onyx entered into an agreement under which Onyx will receive a royalty on any future global net sales of regorafenib in oncology.
About the CORRECT Study
The CORRECT study was an international, multicenter, randomized, double-blind, placebo-controlled Phase 3 study that enrolled 760 patients with mCRC whose disease had progressed during or within 3 months following last administration of approved standard therapies, which must have included fluoropyrimidine, oxaliplatin, irinotecan, bevacizumab and cetuximab or panitumumab.[i]
Patients who had withdrawn from standard treatment due to unacceptable toxicity warranting discontinuation of treatment and precluding retreatment with the same agent prior to progression of disease were also allowed into the study.
Patients were randomized to receive either regorafenib plus best supportive care (BSC) or placebo plus BSC. Treatment cycles consisted of 160 mg of regorafenib (or matching placebo) once daily for three weeks on / one week off plus BSC.[i]
The study was conducted in North America, Europe, China, Japan and Australia.
