NCT02969681

Brief Summary

Preclinical study has shown that human colorectal cancer cells harboring KRAS or BRAF mutations are selectively killed by high levels of ascorbic acid (AA). High dose of AA aslo impairs tumor growth in Apc/KRASG12D mutant mice. Previous phase Ⅰ studies have found that high dose iv AA is well tolerated in cancer patients.This protocol is a phase Ⅲ study of AA infusions combined with treatment with FOLFOX +/- bevacizumab versus treatment with FOLFOX +/- bevacizumab alone as first-line therapy in patients with recurrent or advanced colorectal cancer.
