Brief summary:
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.

Detailed description:

Arms:
arm 1: 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.

Interventions: intervention 1: Regorafenib (Stivarga, BAY73-4506) intervention 2: Oxaliplatin intervention 3: Folinic acid intervention 4: 5-FU (mFOLFOX6)
Intervention descriptions: intervention 1: Subjects will receive regorafenib 160 mg od on days 4 to 10 and days 18 to 24 as four 40 mg coprecipitate tablets. In case of administration as a single agent during the study, regorafenib will be administered 160 mg od for 3 weeks on/1 week off. Each cycle consists of 28 days. intervention 2: On day 1 and day 15 of each cycle, participants will receive 85 mg/m\^2 oxaliplatin as a 2 hour i.v. infusion. intervention 3: On day 1 and day 15 of each cycle, participants will receive folinic acid (either 400 mg/m\^2 D/L-folinic acid or 200 mg/m\^2 L-folinic acid) as a 2 hour i.v. infusion. intervention 4: Participants will receive a 400 mg/m\^2 5 FU i.v. bolus injection immediately followed by a 2400 mg/m\^2 5 FU 46 hour i.v. infusion.
