About

This is a study to evaluate the efficacy (effectiveness) and the safety of regorafenib when given in combination with chemotherapy mFOLFOX6 as first line therapy in patients with metastatic colorectal cancer (CRC). mFOLFOX6 is an approved chemotherapy. Regorafenib is an oral (i.e. taken by mouth) multi-targeted kinase inhibitor. A kinase inhibitor targets certain key proteins that are essential for the survival of the cancer cell. By specifically targeting these proteins, regorafenib may stop cancer growth. The growth of the tumor may be decreased by preventing these specific proteins from functioning.

The primary endpoint (the most meaningful result to be tracked) of this study is based on the rate of response, i.e. the disease getting smaller. The aim is to show that the therapy of colorectal cancer with mFOLFOX6 in combination with regorafenib improves the response rate observed for the standard therapy only.

54 participants in 1 patient group

Regorafenib + oxaliplatin/folinic acid/5-FU (mFOLFOX6)

Experimental group

Description:

On Day 1, participants received 85 mg/m\^2 oxaliplatin as a 2-hour intravenous (IV) infusion and folinic acid (either 400 mg/m\^2 D/L-folinic acid or 200 mg/m\^2 L-folinic acid) as a 2-hour IV infusion. Once the initial infusion was completed, participants received 5-FU 400 mg/m\^2 IV bolus injection immediately followed by a 5-FU 2400 mg/m\^2 IV infusion for 46 hours. The next cycle of mFOLFOX6 was administered on Day 15 to 17. Participants received Regorafenib (Stivarga, BAY73-4506) 160 mg orally (po) once daily (qd) on Days 4 to 10 and Days 18 to 24. One cycle comprised 28 days.
