Brief summary
This is an open label, multi-center, Phase 2 study of BBI608 in combination with cetuximab, panitumumab or capecitabine in patients with advanced colorectal cancer.
Detailed description
This is an open label, multi-center, Phase 2 study of BBI608 administered in combination with either cetuximab, or panitumumab, or capecitabine. A cycle will consist of daily and continuous oral administration of BBI608 for four weeks in combination with either cetuximab, or panitumumab, or capecitabine.
Interventions
BBI608 is administered at 500 mg po bid continuously.
Panitumumab will be administered IV on day 8 and 22 of each 28 day cycle at 6 mg/kg over 60 minutes.
Capecitabine will be administered orally at 1000 mg/m2 bid daily on days 8-21 every three weeks.
Cetuximab will be administered IV on day 5 at 400 mg/m2 intravenous infusion over 120 minutes as the initial dose, then weekly at 250mg/m2 over 60-minutes at subsequent cycles.
