To test the potential of NR as a neuroprotective therapy for PD, we will perform NO-PARK (ClinicalTrials.gov: NCT03568968), a multi-centre, phase II randomized double-blinded clinical trial, comparing NR to placebo in individuals with early stage PD. The central hypothesis of NO-PARK is that oral administration of the NAD precursor NR can boost neuronal NAD levels and ameliorate mitochondrial dysfunction in PD. This, in turn, will rectify neuronal metabolism and inhibit neurodegeneration, resulting in amelioration of clinical symptoms and delayed PD progression.

Individuals with PD (n = 400) are being recruited from centres across all four health regions of Norway. After the initial assessment, participants are randomly assigned to either NR 500 mg x 2/day, or placebo and followed with regular clinical examination, brain imaging and blood tests for a total period of one year. This work aims to discover and develop a therapy with the potential to delay the progression of PD.
