- Number of participants with treatment related adverse events as assessed by CTCAE v4.0 in absence and presence of esomeprazole [ Time Frame: Through study completion, approximately 0.5 year ]
- The Tmax of regorafenib alone and regorafenib with esomeprazole (concomitantly and 3 hours before regorafenib intake respectively) will be related [ Time Frame: T=0, 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 6h, 8h, 12h, 24h at day 21, day 49 and day 77 ]The Tmax of regorafenib will be determined by multiple blood samples at T=0, 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 6h, 8h, 12h, 24h at day 21, day 49 and day 77
- The clearance of regorafenib alone and regorafenib with esomeprazole (concomitantly and 3 hours before regorafenib intake respectively) will be related [ Time Frame: T=0, 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 6h, 8h, 12h, 24h at day 21, day 49 and day 77 ]The clearance of regorafenib will be determined by multiple blood samples at T=0, 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 6h, 8h, 12h, 24h at day 21, day 49 and day 77
