Phase III, Multi-Center, Study to Assess the Clinical Effect of Droxidopa in Subjects With Primary Autonomic Failure, Dopamine Beta Hydroxylase Deficiency or Non-Diabetic Neuropathy and Symptomatic NOH
The purpose of this study is to see whether droxidopa is effective in treating symptoms of neurogenic orthostatic hypotension in patients with Primary Autonomic Failure (Pure Autonomic Failure, Multiple System Atrophy, Parkinson's Disease), Non-diabetic neuropathy, or Beta Hydroxylase deficiency.
• Male or female and aged 18 years or over;
• Clinical diagnosis of orthostatic hypotension associated with Primary Autonomic Failure (PD, MSA and PAF), Dopamine Beta Hydroxylase Deficiency or Non-Diabetic Autonomic Neuropathies;
• A documented fall in systolic blood pressure of at least 20 mmHg, or in diastolic blood pressure of at least 10 mmHg, within 3 minutes after standing;
• Provide written informed consent to participate in the study and understand that they may withdraw their consent at any time without prejudice to their future medical care.
