Clinical Trial Summary

The purpose of this study is to determine the efficacy of Droxidopa for the treatment of fatigue in patients with Parkinsonism by the Visual Analog Fatigue Scale (VAFS). This is a randomized, placebo-controlled, double-blind clinical trial for 3 months where half the subjects will receive placebo and the other half will receive Droxidopa. Following this will be a wash-out period of 7 days and then all subjects will receive Droxidopa for 3 months during the open-label phase.

Description:

Parkinsonism, is a group of symptoms seen in several diseases, including Parkinson's Disease. In Parkinsonism, a patient may become stiff, have smaller and slower movements, develop a tremor (shaking of the arms or legs), have decreased facial expression, and a softer voice. Fatigue is a common symptom that causes suffering and stress in diseases that affect the brain. Over 50% of patients with Parkinsonism report fatigue as one of their top three symptoms that make their life more difficult. Currently, there are no evidence-based guidelines for treating fatigue in Parkinson's Disease, and no effective medications or therapeutic modalities exist for fatigue symptoms in patients with Parkinson's Disease. Droxidopa (also known by the trade name NORTHERA) is a safe and well tolerated medication which has been approved in USA for the treatment of orthostatic dizziness or light headedness in patients with a clinical diagnosis of symptomatic Neurogenic Orthostatic Hypotension associated with primary autonomic failure (Parkinson's Disease and Multiple System Atrophy), Dopamine Beta Hydroxylase Deficiency, or Non Diabetic Autonomic Neuropathy. Fatigue may be due to diminished levels of norepinephrine in Parkinson's Disease. The locus coeruleus, one of the major sources of norepinephrine, is affected during the preclinical phase of Parkinson's Disease during stage 2 of Braak pathology staging. Norepinephrine is the final metabolite of dopamine, therefore by adding exogenous norepinephrine, it may be possible to control some of the motor and non-motor symptoms of Parkinsonism. Norepinephrine is the final metabolite of droxidopa, and it is still unclear if it passes the blood-brain barrier. This pilot study is to measure the efficacy and safety of droxidopa in Parkinsonism patients with fatigue.
