Brief summary
This study will test the safety of treating colorectal cancer with a combination of drugs. The current standard treatments of FOLFOX6 or CapeOx will be give in combination with the GSK investigational drug pazopanib.
Interventions
Pazopanib is an oral inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-kit kinases
FOLFOX 6 treatment consists of intravenous (IV) oxaliplatin (100 milligram per meter\^2\[mg/m\^2\]), and folinic acid (400 mg/m\^2), IV 5-fluorouracil bolus (400 mg/m\^2) followed by IV 5-fluorouracil (2400 to 3000 mg/m\^2) infusion over 48 hours on Day 1 of every 14-day cycle.
CapeOx treatment consists of IV oxaliplatin (130 mg/m\^2) on Day 1 plus oral capecitabine (1000 mg/m\^2) twice daily on Days 2 through 14 of every 21-day cycle. Reduced CapeOx treatment will be administered according to the same schedule as the CapeOx treatment, but the dose of capecitabine will be reduced to 850 mg/m\^2 twice daily.
