Brief Summary

The primary aim of this study is to test whether the combination of valproic acid with bevacizumab and oxaliplatin/fluoropyrimidine regimens (mFOLFOX6/mOXXEL) can prolong progression free survival (PFS) as compared with bevacizumab and oxaliplatin/fluoropyrimidine regimens alone as first-line treatment in patients with metastatic colorectal cancer with mutation of RAS.

Detailed Description

Patients will be randomized 1:1 to receive oxaliplatin based chemotherapy (mFOLFOX6/mOXELL) plus bevacizumab for 12 cycles or the same chemotherapy plus bevacizumab and valproic acid for 12 cycle.

Thereafter, in both arms, patients who are progression free after 12 cycles (24 weeks) of treatment continue maintenance bevacizumab+fluoropyrimidines until disease progression or unacceptable toxicity.

Surgery may be carried out in case of appropriate tumour reduction is evident at response evaluation. Resectability has to be evaluated by a multidisciplinary review team and the decision regarding post-surgery chemotherapy is at the discretion of the investigators, according to the policy commonly adopted by their Institution in clinical practice.
