About this study

Official title: A Phase I, Open-Label, Single-Dose, Two-Part Study to Assess the Pharmacokinetics of Gepotidacin (GSK2140944) in Male and Female Adult Participants With Varying Degrees of Hepatic Impairment and in Matched Control Participants With Normal Hepatic Function

This is a two-part study which will evaluate the PK, safety, and tolerability of a single 1500 milligram (mg) oral dose of gepotidacin in subjects with normal hepatic function and in subjects with mild, moderate, and severe hepatic impairment. In Part 1, subjects with moderate hepatic impairment and subjects with normal hepatic function will be enrolled. Matching subjects with normal hepatic function in Part 1 (Group D), will be enrolled following the completion of all Day 3 assessments of the respective matched, hepatically impaired subject. In Part 2, subjects with mild (optional) and severe hepatic impairment and subjects with normal hepatic function will be enrolled concurrently based on the PK, safety, and tolerability data of Part 1. Subjects with mild hepatic impairment, may be studied if there is a significant difference in PK between subjects with moderate hepatic impairment and subjects with normal hepatic function. Subjects with severe hepatic impairment, will be studied in Part 2, provided that, the PK objectives are achieved in Part 1. A totals of 48 subjects, are planned to be enrolled in the study. The study duration is approximately of 44 days from Screening to Follow-up visit. The results from this study will enable the development of appropriate dosing recommendations in subjects with impaired hepatic function.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Gepotidacin in people with Infections, Bacterial, run by GlaxoSmithKline 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 9 inclusion and 34 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 12 Apr 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?

Yes. Results are posted in the registry (first posted 17 Dec 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Area Under the Plasma Concentration-time Curve (AUC) From Time Zero (Pre-dose) Extrapolated to Infinity (AUC[0-inf]) for Plasma Gepotidacin (time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 36 and 48 hours post-dose). The study lists 2 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 NCT03562117.

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 12 Apr 2021.
