Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosed with symptomatic orthostatic hypotension due to Parkinson's disease, multiple system atrophy, or pure autonomic failure, (i.e. neurogenic orthostatic hypotension).
  • At screening, subject must meet the diagnostic criteria of neurogenic orthostatic hypotension, as demonstrated by a ≥ 30 mm Hg drop in systolic blood pressure (SBP) within 5 minutes of standing.
  • Impaired autonomic reflexes, as determined by absence of BP overshoot during phase IV of the Valsalva maneuver, in subjects where Valsalva is performed, as appropriate.
  • For the optional open-label extension study subjects must have demonstrated a pressor effect and completed dosing in Cohort 1.

Exclusion Criteria:

  • Systemic illnesses known to produce autonomic neuropathy, including but not limited to diabetes mellitus, amyloidosis, monoclonal gammopathy of unknown significance, and autoimmune neuropathies.
  • Concomitant use of vasoconstricting agents for the purpose of increasing BP such as ephedrine, dihydroergotamine, or midodrine must stop taking these drugs at least 2 days or five half-lives (whichever is longer) prior to dosing on Day 1 and throughout the duration of the study.
  • Concomitant use of anti-hypertensive medication for the treatment of essential hypertension unrelated to autonomic dysfunction.
  • Known or suspected alcohol or substance abuse within the past 12 months.
