Research suggests bowel cancer medication could help combat earlyonset Parkinsons disease

People with certain forms of early-onset Parkinson’s disease could potentially benefit from taking a medication used to treat certain forms of cancer, according to new research by Leicester scientists and funded by the Medical Research Council.

The study, which has been published in Science Matters, suggests that folinic acid, which is used in medications to treat bowel cancer, could also potentially protect neurons associated with Parkinson’s disease.

Dr Miguel Martins from the MRC Toxicology Unit at our University explained: “Parkinson’s disease is a disabling disorder for which no cure is yet available; further, after dopaminergic neurons are lost, only a few palliative treatment options for Parkinson’s symptoms are available. Therefore, treatments that either prevent or delay the onset of the disease at an early stage are needed.

“Folinic acid is already approved and used for applications in the clinic as an adjuvant during chemotherapy and can be administered orally, as a dietary supplement, or intravenously.

“Thus, the drug safety risk is low, and drug development for repurposing folinic acid as a treatment for Parkinson’s disease would be faster than for a novel drug.

“With this in mind, it seems worthwhile to further test the supplementation of folinic acid in clinical trials as a potential preventative or palliative therapeutic for PD and to expand the repertoire of treatment options.”

Previous research by the team has shown that folic acid protects neurons in models of Parkinson’s disease. Folinic acid is related to folic acid but is metabolically more active.
