Effects of High-dose Coenzyme Q10 on Biomarkers of Oxidative Damage and Clinical Outcome in Parkinson Disease

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01892176
Recruitment Status : Completed

Brief Summary:
The investigators hypothesise that measuring biomarkers of oxidative damage could better inform investigators on the potential merits (and pitfalls) of CoQ10 supplementation in PD subjects.

Condition or disease Intervention/treatment Phase
Parkinson Disease Dietary Supplement: coenzyme q10 Phase 2 Phase 3

Detailed Description:
Subjects with idiopathic PD will be recruited to a 10-week dose escalation study. Each dosage (400mg/day, 800mg/day, 1200/day and 2400mg/day) will be consumed daily for two weeks. Information on safety and fasting blood/urine samples will be collected. Primary endpoint is plasma F2-isoprostanes (adjusted for arachidonate) while secondary endpoint is the change in the total Unified Parkinson Disease Rating Scale (UPDRS) before and after treatment. Serum phospholipase A2 activities, plasma all trans-retinol, plasma total tocopherol (sum of α-, δ- and γ-tocopherol) and serum uric acid will be measured.
