About this study

Official title: A Phase 1, Open-Label, Single Dose Study to Evaluate the Pharmacokinetics of Ampreloxetine Following a Single-dose in Subjects With Mild, Moderate, and Severe Hepatic Impairment and in Matching Healthy Subjects

An open-label study to characterize the effects of mild, moderate, and severe Hepatic Impairment (HI) on the pharmacokinetics (PK) of ampreloxetine following a single oral dose in comparison with healthy volunteers with normal hepatic function.

Read the detailed description

This is a multicenter, non-randomized, open label, parallel group, single dose, 2-part study being conducted in adult subjects with mild, moderate, or severe HI (Child-Pugh Class A, B, and C), and in matching healthy subjects. The healthy matching group will be comparable to the corresponding hepatic impairment groups by matching subjects by weight (±20% of group mean), age (±10 years of group mean), and sex (equal ratios across groups).

The study will be conducted in two sequential parts:

In Part A, following a 28-day screening period, 6 subjects each with mild or moderate HI and 6 matching healthy subjects who meet eligibility criteria will be enrolled and administered a single Dose A (Day 1).

In Part B, following a 28-day screening period, 6 subjects with severe hepatic impairment will receive a single Dose A (Day 1). Furthermore, the Sponsor may choose to enroll up to 6 additional healthy subjects in Part B to ensure matching of subjects across all groups for weight, age, and sex is maintained.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma AUC0-t

    Estimation of Area under the concentration-time curve, from time zero to the last measured time point

    Measured: Plasma AUC0-t will be measured Day 1 to Day 15

  2. Plasma AUC0-inf

    Estimation of AUC from time zero extrapolated to infinity

    Measured: Plasma AUC0-inf will be measured from Day 1 to Day 15

  3. Plasma Cmax

    Estimation of maximum observed plasma concentration

    Measured: up to Day 21

Secondary outcomes (2)
  1. Number of subjects with clinically significant vital sign abnormalities

    Clinically significant abnormalities in vital signs will be listed and described

    Measured: up to Day 21

  2. Number of subjects with change in C-SSRS scores

    Changes in Columbia suicide severity rating scale (C-SSRS) scores will be listed and described

    Measured: up to Day 21

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ampreloxetine in people with Symptomatic Neurogenic Orthostatic Hypertension and nOH, run by Theravance Biopharma at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma AUC0-t (time frame: Plasma AUC0-t will be measured Day 1 to Day 15). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04200573, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2021.
