Eligibility | 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 Part A. 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 be stopped at least 2 days or five half lives (whichever is longer) prior to dosing on Day 1 of Part A and C, and throughout the duration of Part C. Subjects previously enrolled in Part A under previous versions of the protocol will continue taking fludrocortisone during the washout period and in Part C at the dose and regimen used in Part A. For new subjects enrolling in Part A under Amendment 3, fludrocortisone use in both Parts of the study and during the washout period will be limited to 0.1 mg QD. - 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. |

Primary | Part A: Change From Time-matched Placebo in Seated Systolic Blood Pressure (SBP) | Placebo referred to the Day 1 visit, and the change from placebo referred to the time-matched difference from each TD-9855 dosing day (Days 2 through 5) relative to placebo dosing (Day 1). | 7 hours post-dose on Day 1 (Placebo dosing) and on each of Days 2 to 5 (TD-9855 dosing) | |
Primary | Part B: Change From Baseline in Seated SBP | Baseline was defined as the pre-dose measurement on Day 1 of Part B. | Baseline and 7 hours post-dose on Day 1 | |
Primary | Part C: Change From Baseline in Likert Scale Score at Week 4 | The Likert Scale is question 1 of the Orthostatic Hypotension Symptom Assessment (OHSA). The question asks participants to rate the severity of their orthostatic hypotension symptoms (dizziness, lightheadedness, feeling faint, or feeling like you might black out) on an 11-point scale from 0 to 10, with 0 indicating no symptoms/no interference and 10 indicating the worst possible symptoms/complete interference. A higher score indicates a worse outcome. Baseline was defined as the pre-lunch measurement on Day -1. | Baseline to Week 4 | |
Secondary | Part A and Part B: Change From Baseline in Likert Scale Score at 6 to 8 Hours | The Likert Scale is question 1 of the Orthostatic Hypotension Symptom Assessment (OHSA). The question asks participants to rate the severity of their orthostatic hypotension symptoms (dizziness, lightheadedness, feeling faint, or feeling like you might black out) on an 11-point scale from 0 to 10, with 0 indicating no symptoms/no interference and 10 indicating the worst possible symptoms/complete interference. A higher score indicates a worse outcome. Baseline was defined as the pre-dose measurement on Day 1 for Part A and Part B. Data was collected a one point between 6 and 8 hours post-dose. | Baseline to a single time point between 6 to 8 hours post-dose | |
Secondary | Part A and Part B: Change From Baseline in the Composite Orthostatic Hypotension Symptom Assessment (OHSA) Score | The OHSA is made up of a 6-item symptoms assessment. All items were scored on an 11-point scale from 0 to 10, with 0 indicating no symptoms/no interference and 10 indicating the worst possible symptoms/complete interference. Activities that were marked as zero or "cannot be done for other reasons" at baseline were not included in the scoring. The composite OHSA score is the average of the response scores (for non-missing data) to the 6 questions of OHSA. A reduction in composite score indicates an improvement in symptoms. Baseline was defined as the pre-dose measurement on Day 1 for Part A and Part B. Data was collected a one point between 6 and 8 hours post-dose. | Baseline to a single time point between 6 to 8 hours post-dose | |
Secondary | Part A: Change From Time-matched Placebo in Standing SBP | Placebo referred to the Day 1 visit, and the change from placebo referred to the time-matched difference from each TD-9855 dosing day (Days 2 through 5) relative to placebo dosing (Day 1). SBP was measured after 5 minutes of standing. | 4 and 7 hours post-dose on Day 1 (Placebo dosing) and on each of Days 2 to 5 (TD-9855 dosing) | |
Secondary | Part B: Change From Baseline in Standing SBP | SBP was measured after 3 minutes of standing. Baseline was defined as the pre-dose measurement on Day 1 of Part B. | Baseline, 4 and 7 hours post-dose on Day 1 | |
Secondary | Part A: Change From Time-matched Placebo in Seated SBP | Placebo referred to the Day 1 visit, and the change from placebo referred to the time-matched difference from each TD-9855 dosing day (Days 2 through 5) relative to placebo dosing (Day 1). | 4, 7, 9, 12 hours post-dose on Day 1 (placebo) and Days 2 to 5 (TD-9855 dosing) | |
Secondary | Part B: Change From Baseline in Seated SBP | Baseline was defined as the pre-dose measurement on Day 1 of Part B. | Baseline and 4, 7, 9 and 12 hours post-dose on Day 1 | |
Secondary | Part A: Change From Time-matched Placebo in Duration of Standing During the Orthostatic Standing Test (OST) | Blood pressure (BP) and heart rate (HR) measurements were recorded with automated (or manual) sphygmomanometer, after being seated for 5 min and 10 min, and after standing for 1, 3, 5, and 10 min. The standing time was measured with a chronometer and the duration of standing was recorded.
