Details and patient eligibility


The investigators propose a phase II clinical trial with the objective to investigate the potential clinical interest to associate regorafenib with a metronomic chemotherapy combining capecitabine, cyclophosphamide and low-dose aspirin, for the treatment of patients with metastatic colorectal cancer. The main objective of the study will be to achieve 15% of objective response rate in patients treated with multimodal metronomic chemotherapy and regorafenib.

Experimental group
REGORAFENIB: For the first cycle: regorafenib will be administered according to the "REDOS" schedule (80 mg daily for week 1, 120 mg daily for week 2 and 160 mg daily for the third week of the first cycle). For the following cycles: regorafenib will be administered at a 80, 120 or 160 mg daily dose according to toxicity observed with the last dose used in the first cycle. METRONOMIC CHEMOTHERAPIES: Capecitabine: 625mg/m²/orally twice daily continuously for 6 months Cyclophosphamide: 50 mg per os, daily, for 6 months ASPIRIN: 75 mg orally and daily until progression
