Study Description

Brief 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.

Detailed 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.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Droxidopa The Droxidopa starting dose for all eligible patients in the Titration Periods are 100mg three times daily (TID). Doses will be titrated by 100mg TID; increments will be made weekly until the optimal dose is achieved or the subject doesn't notice an improvement in their subjective fatigue on a higher dose compared to the most recent dose. Half of the subjects will be on Droxidopa for 3 months during the double-blind phase. All subjects will be on Droxidopa for 3 months during the open-label phase.	Drug: Droxidopa Droxidopa in 100, 200, and 300mg capsules. Maximum dose to be used in this study is 600mg. Other Name: Northera
Placebo Comparator: Placebo Oral Tablet The placebo starting dose for all eligible patients in the Titration Period is 100mg TID. Doses will be titrated by 100mg TID; increments will be made weekly until the optimal dose is achieved. Half of the subjects will be on placebo for 3 months during the double-blind phase.

Outcome Measures

Primary Outcome Measures :

Efficacy of Droxidopa on fatigue in subjects with Parkinsonism as determined by completion of Visual Analogue Fatigue Scale (VAFS) [ Time Frame: Change between baseline and 12 weeks ]
Subjects will complete the VAFS which measures level of fatigue with zero being equivalent to energetic with no fatigue to ten being worst possible fatigue
Efficacy of Droxidopa on fatigue in subjects with Parkinsonism as determined by completion of Visual Analogue Fatigue Scale (VAFS) [ Time Frame: Change between 18 weeks and 28 weeks ]
Subjects will complete the VAFS which measures level of fatigue with zero being equivalent to energetic with no fatigue to ten being worst possible fatigue
Efficacy of Droxidopa on fatigue in subjects with Parkinsonism as determined by completion of Visual Analogue Fatigue Scale (VAFS) [ Time Frame: Week 29 ]
Subjects will complete the VAFS which measures level of fatigue with zero being equivalent to energetic with no fatigue to ten being worst possible fatigue

Secondary Outcome Measures :

Efficacy of Droxidopa on motor and non-motor symptoms of Parkinsonism as determined by the Unified Parkinson's Disease Rating Scale (UPDRS) [ Time Frame: Change between baseline and 12 weeks ]
The UPDRS is a composite measurement of motor and non-motor symptoms divided into six domains. Domain I measures Mentation, Behavior and Mood. Domain II measures Activities of Daily Living. Domain III measures Motor Examination. Domain IV measures Complications of Therapy. Domain V is Modified Hoehn and Yahr Staging. Domain 6 is Schwab and England Activities of Daily Living Scale
