Condition or disease Intervention/treatment Phase
Symptomatic Neurogenic Orthostatic Hypotension Drug: ampreloxetine Phase 3

Detailed Description:
This is a Phase 3, multi-center, open-label study to evaluate the safety and tolerability of ampreloxetine in subjects with primary autonomic failures (MSA, PD, and PAF) and symptomatic nOH.

Primary Purpose: Treatment
Official Title: A Phase 3, 182-week, Open-Label, Extension Study to Investigate the Safety and Tolerability of TD-9855 in Treating Symptomatic Neurogenic Orthostatic Hypotension (Symptomatic nOH) in Subjects With Primary Autonomic Failure
Actual Study Start Date : September 19, 2019
Actual Primary Completion Date : November 12, 2021
Actual Study Completion Date : November 12, 2021


Arm Intervention/treatment
Experimental: ampreloxetine
Participants will receive a single, oral, daily dose of active drug (TD-9855) for 182 weeks.
Drug: ampreloxetine
Oral tablet, QD
Other Name: TD-9855




Primary Outcome Measures :
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) [ Time Frame: Day 1 up to a maximum of 749 days ]

    An adverse event (AE) was any untoward medical occurrence in a patient or clinical study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. A TEAE was defined as any AE that begins on or after the date of first dose of study drug up to the date of last dose of study drug plus the number of days in the follow-up period.

    Clinically significant abnormalities in physical and neurological examinations, vital signs, resting 12-lead electrocardiograms, and clinical laboratory evaluations, in addition to incidence of fall, suicidal ideation, and suicidal behavior, were reported as AEs.
