Abstract Background Falls are a common complication of Parkinson’s disease. There is a need for new therapeutic options to target this debilitating aspect of the disease. Cholinergic deficit has been shown to contribute to both gait and cognitive dysfunction seen in the condition. Potential benefits of using cholinesterase inhibitors were shown during a single centre phase 2 trial. The aim of this trial is to evaluate the effectiveness of a cholinesterase inhibitor on fall rate in people with idiopathic Parkinson’s disease. Methods This is a multi-centre, double-blind, randomised placebo-controlled trial in 600 people with idiopathic Parkinson’s disease (Hoehn and Yahr stages 1 to 4) with a history of a fall in the past year. Participants will be randomised to two groups, receiving either transdermal rivastigmine or identical placebo for 12 months. The primary outcome is the fall rate over 12 months follow-up. Secondary outcome measures, collected at baseline and 12 months either face-to-face or via remote video/telephone assessments, include gait and balance measures, neuropsychiatric indices, Parkinson’s motor and non-motor symptoms, quality of life and cost-effectiveness. Discussion This trial will establish whether cholinesterase inhibitor therapy is effective in preventing falls in Parkinson’s disease. If cost-effective, it will alter current management guidelines by offering a new therapeutic option in this high-risk population. Trial registration REC reference: 19/SW/0043.

Abstract BackgroundParkinson’s Disease (PD) patients have lower niacin levels compared to their spouses. The main objective was to study low-dose daily niacin supplementation versus placebo on motor symptoms in Parkinson’s disease subjects.MethodsA randomized, placebo-controlled, double-blind, single-center clinical trial in Parkinson’s disease patients was performed in Augusta, GA, between September 2016 to September 2019. Randomized participants were 47 PD patients who received either low-dose niacin (N = 21 ) or placebo (N = 26) for the first six months (mean age 68.4 SD, 8.7; mean duration of disease 5.8 SD 4.9; H&Y scores between 0.5 to 4; 64% subjects were Veterans). The Veterans Affairs Pharmacy generated the randomized sequence. After the double-blind phase, all participants received open-label niacin for the next six months. All patients were evaluated at baseline, six months, and one year of treatment. The main outcome measure was the Unified Parkinson’s Disease Rating Scale III (UPDRS III) scores. Secondary outcome measures were depression, sleep quality, mental flexibility and cognition, and physical fatigue.Results39 subjects were analyzed with low-dose niacin (N = 18) and placebo (N = 21) for the completion of the first six months (randomized, double-blind), and 31 subjects were analyzed for the completion of the next six months (open-label) with low-dose niacin (N = 14) and placebo (N = 17). Niacin treatment was not tolerated by two subjects. The baseline mean UPDRS III score was 21.3 ± 15.8 for the niacin group and 22.4 ± 11.8 for placebo. The change with six months of placebo was 0.05 [95% CI, -2.4 to 2.32], and niacin was 1.06 [95% CI, -3.68 to 1.57]. From six to twelve months, the average UPDRS III score decreased for the placebo group by 4.58 [95% CI, -0.85 to 8.30] and the niacin group by 4.63 [95% CI, 1.42 to 7.83]. Eight subjects withdrew from the study before the 6-month time point and eight more before the one-year time point due to voluntary discontinuation, flushing, or inability to continue (SARS-CoV-2 shut-down).ConclusionLow-dose niacin supplementation may be helpful as an adjunct therapy in improving motor function in PD.Trial registrationClinicaltrials.gov, NCT03462680.

The main objective was to study low-dose daily niacin supplementation on motor symptoms in Parkinson's disease subjects. Methods Forty-Seven PD patients were randomly assigned to receive low-dose niacin or placebo in a randomized, double-blind study for the first six months. After the double-blind phase, all participants received open-label niacin for the next six months. All patients were evaluated at baseline, six months, and one year of treatment. The main outcome measure was the Unified Parkinson's Disease Rating Scale III (UPDRS III) scores. Secondary outcome measures were depression, sleep quality, mental flexibility and cognition, and physical fatigue. Results Niacin treatment was tolerated well by 45 subjects. The baseline mean UPDRS III score was 21.3 ± 15.8 for the niacin group and 22.4 ± 11.8 for placebo. The change with six months of placebo was 1.5 [95% CI, -0.73 to 3.73], and niacin was − 1.06 [95% CI, -3.68 to 1.57]. From six to twelve months, the average UPDRS III score decreased for the placebo group by 2.66 [95% CI, -0.95 to 6.24] and the niacin group by 4.63 [95% CI, 1.42 to 7.83]. Eight subjects withdrew from the study before the 6-month time point and eight more before the one-year time point due to voluntary discontinuation, flushing, or inability to continue (SARS-CoV-2 shut-down).

A six-month double-blind, placebo-controlled randomized study was conducted to ascertain whether low-dose daily niacin supplementation would improve motor symptoms in Parkinson’s disease (PD) patients. A total of 47 PD patients were assigned to receive low-dose niacin or a placebo. At the end of the double-blind phase, all participants received open-label niacin for the next six months. All patients were evaluated at baseline, after six months, and after one year of treatment. The primary outcome measure was the Unified Parkinson’s Disease Rating Scale III (UPDRS III) scores. Secondary outcome measures were depression, sleep quality, mental flexibility and cognition, and physical fatigue. Niacin treatment was well-tolerated by forty-five subjects. The mean [95% CI] change in UPDRS III scores at six months of placebo was −0.05 [95% CI, −2.4 to 2.32], and niacin was −1.06 [95% CI, −3.68 to 1.57]. From six to twelve months when both groups received open-label niacin supplementation, the average UPDRS III scores significantly decreased for the placebo group by 4.58 [95% CI, −0.85 to 8.30] and the niacin group by 4.63 [95% CI, 1.42 to 7.83] points. Low-dose niacin supplementation is a well-tolerated adjunct therapy and may improve motor function in PD when taken over a longer period.
