Trattamento sperimentale: 

Arm B: Regorafenib 160 mg, 4 tablets once daily on days 1-21, every 4 weeks, until intolerance or progression disease

Trattamento di controllo: 

Arm A: Placebo 4 tablets once daily on day 1-21, every 4 weeks, until intolerance or progression disease

Obiettivi primari dello studio: 

Progression Free Survival 1 (PFS1)
Imaging studies will be performed at baseline, 8, 16, 24 and 32 weeks, and then every 12 weeks. The objective (confirmed) response and the progression-free survival will be assessed by RECIST criteria. Progression free survival will be calculated for all patients from the date of randomization until the date PD or death is first reported.

Obiettivi secondari dello studio: 

- Overall Survival
- Response Rate (RR, complete response or partial response)
- Other variables:
  Progression Free Survival (PFS2)
- safety and tolerability of regorafenib,
- patient treatment-related symptoms as measured by the European Organization for research and treatment of cancer EORTC QLQ-C30, (days 1, week , 8, 16, 24, 32) , for patients in each treatment arm.
- genetic mutational profile of the tumors with the PFS, OS and RR of the patients
