Vitamin C Enhances Epigenetic Treatments in Acute Myeloid Leukemia and Myeloid Dysplastic Syndrome

Research using cancer cell lines demonstrated that supplementing standard epigenetic therapy with vitamin C enhanced the drug's antineoplastic action, according to a report in the Proceedings of the National Academy of Sciences.1

In the cell lines, the addition of vitamin C to decitabine treatment increased cancer cell growth inhibition, triggering cellular self-destruction.

In an ongoing pilot clinical trial in Copenhagen, Denmark, investigators are combining vitamin C with azacitidine, the standard-of-care therapy for myeloid dysplastic syndrome (MDS) and acute myeloid leukemia (AML). The approach would also correct a vitamin C deficiency, which occurs in many patients with cancer.

If the pilot trial is successful, the investigators plan a larger trial to explore the potential of this strategy to improve treatments for AML and MDS.

A blinded clinical trial that measures azacitidine combined with vitamin C vs placebo would be needed to validate any benefits of adding vitamin C to a treatment. Furthermore, there is no evidence that these benefits would work for other cancers or other chemotherapies.

Preliminary results are expected by spring or summer 2017.
