Official Title: A Multi-center, Double-blind, Randomized, Parallel-Group, Placebo-Controlled Study to Assess the Clinical Effect of Droxidopa in the Treatment of Symptomatic Neurogenic Orthostat
Brief Summary:
This is a study to evaluate the effects of an investigational drug, Droxidopa, in participants with neurogenic orthostatic hypotension (NOH), associated with Parkinson's disease. Droxidopa is being studied to determine the effects on blood pressure changes upon standing up (orthostatic challenge). Symptoms and activity measurements, including patient reported falls, will be evaluated to determine the effectiveness of the study drug.
Symptoms of NOH may include any of the following:
The study duration is a maximum of approximately 14 weeks including up to 2 weeks for screening, up to 2 weeks for proper dose finding, followed by an 8 week treatment period and a follow-up visit after 2 weeks. A sufficient number of patients will be screened to allow approximately 211 randomized patients. An extension study is also available to continue treatment if determined appropriate by the study doctor. This Study is NCT01132326 sponsored by Chelsea Therapeutics and is enrolling by invitation only.
