Valproic Acid in Combination With Bevacizumab and Oxaliplatin/Fluoropyrimidine Regimens in Patients With Ras-mutated Metastatic Colorectal Cancer

Phase 2
Recruiting
Conditions
Ras-mutated Metastatic Colorectal Cancer
Interventions
Registration Number
NCT04310176
Lead Sponsor
National Cancer Institute, Naples
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.

Primary Outcome Measures
NameTimeMethod
progression-free survival (PFS)until progression of disease (up to 5 years)

PFS is defined as the time elapsed from the date of randomization to the date of progression, as defined by investigators, or the date of death, whichever comes first

Secondary Outcome Measures
NameTimeMethod
overall survival (OS)5 years

OS is defined as the time elapsed from randomization to death due to any cause

centrally reviewed PFS (CR-PFS)at week 12th and 24th and thereafter every 12 weeks until progression of disease (up to 5 years(

FSCR is also measured as the time elapsed from the date of randomization to the date of progression, as defined by independent blind central review, or the date of death, whichever comes first

Determination of changes in quality of lifeat baseline, at week 12th and 24th and every 12 weeks thereafter until progression disease (up to 5 years)

EORTC QLQ-C30, a quality of life questionnaires, composed by 30 items graded from1 (not at all) to 4 (very much) after 1 year from the diagnosis

Number of participants with treatment-related side effectsbaseline, day 1 of each cycle and on maintenance treatment until progression disease (up to 5 years)

graded according to Common Criteria for Adverse Events (CTCAE) version 5.0

metastases resection rate (R0/R1/R2)up to 24 weeks

determined at surgery (resection status) by pathologist follow: R0 no cancer cells at the resection margin; R1 microscopic positive margin, R2 macroscopic positive margin

Response rateat week 12th and 24th and thereafter every 12 weeks until progression of disease (up to 5 years)

according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
