Objectives

Narrative objectives1

We assumed that reduced CoQ10 showed the neuroprotective effects on patients with Parkinson disease (PD). We examine two groups; one group included subjects who have wearing off (A-group), and another group included subjects who have not been medicated with levodopa (B-group).

Assessment

Primary outcomes

UPDRS
A group : Change from baseline to 8th, 24th, 48th week, and post 8th week.
B group : Change from baseline to 8th, 24th, 48th, 72th, 96th week, and post 8th week.

Key secondary outcomes

1. Duration to protocol ended because of addition of levodopa or progression of disease.
2. A group : Change from baseline to 8th, 24th, 48th week, and post 8th week of time of daily on-time or off-time in their diary.
3. Progression of dyskinesia
4. Serum concentration of reduced CoQ10 of baseline, 8th, 24th, 48th week, and post 8th week.
Safety analysis
1) Adverse events except dyskinesia.
2) Screening laboratory studies included complete blood count, level of total protein, albumin, alkaline phosphatase, aspartate transaminase, alanine transaminase, serum urea nitrogen, calcium, chloride, creatinine, glucose, lactate dehydrogenase, potassium, sodium, creatinine kinase, uric acid, choline esterase, LDL-cholesterol, HDL-cholesterol and triglyceride.

Results

Methods:Rondomized, double-blind, placebo controlled, parallel-group pilot trials were conducted to assess the efficacy of ubiquinol-10 in Japanease patients with PD. Participants were divided two groups: PD experiencing wearing off (Group A), and early PD, without levodopa (Group B). Participants took 300mg of ubiquinol-10 or placebo per day for 48 weeks (GroupA) or 96 weeks (Group B).
Results: In Group A, total Unified Parkinson's Disease Rating Scale (UPDRS) scores decreased in the ubuquinol-10 group (n=14; mean+-SD [-4.2+-8.2]), indicating improvement in symptoms. There was a statistically siginificant difference (p <0.05) compared with the placebo group (n= 12;2.9+--8.9). In Group B, UPDRS increased in the ubiquinol-10 group (n=14; 3.9+-8.0), as well as in the placebo group (n=8; 5.1+--10.3).
Conclusions; Ubiquinol-10 may significantly improve PD with wearing off, as judged by total UPDRS scores, and that ubiqionol-10 is safe and well tolerated.
