About this study

Official title: A Phase 1, Open-Label, Study to Evaluate Single Dose Pharmacokinetics, Safety, and Tolerability of Methylnaltrexone (MNTX) in Volunteers With Impaired Hepatic Function

This is a multicenter, non-randomized, single-dose, parallel-group study. Each subject will receive a subcutaneous dose of MNTX. Eight subjects with normal hepatic function and eight subjects from each classification of hepatic impairment will be enrolled. Plasma samples will be collected before and at specified intervals after dosing and the concentration of MNTX will be analyzed.

What is being measured

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

  1. Plasma Concentration of SC MNTX

    To evaluate the pharmacokinetics of MNTX administered subcutaneously as a single dose in individuals with impaired liver and hepatic function compared to healthy controls.

    Measured: 20 days

Secondary outcomes (4)
  1. Time of Maximum Plasma Concentration of SC MNTX

    To evaluate the pharmacokinetics of MNTX administered subcutaneously as a single dose in individuals with impaired liver and hepatic function compared to healthy controls.

    Measured: 20 days

  2. Area Under the Plasma Concentration versus Time Curve (AUC) of SC MNTX

    To evaluate the pharmacokinetics of MNTX administered subcutaneously as a single dose in individuals with impaired liver and hepatic function compared to healthy controls.

    Measured: 20 days

  3. Percentage of SC MNTX Excreted in Urine

    To evaluate the pharmacokinetics of MNTX administered subcutaneously as a single dose in individuals with impaired liver and hepatic function compared to healthy controls.

    Measured: 20 days

  4. Urinary Clearance of SC MNTX

    To evaluate the pharmacokinetics of MNTX administered subcutaneously as a single dose in individuals with impaired liver and hepatic function compared to healthy controls.

    Measured: 20 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SC Methylnaltrexone (MNTX) in people with Liver Dysfunction, run by Bausch Health Americas, Inc. at 1 site 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 3 inclusion and 4 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 27 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 Concentration of SC MNTX (time frame: 20 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 27 Nov 2019.
