About this study

Official title: A Two-part Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of a High, Single Oral Dose of GSK1278863 (Part A), and a Randomized, Single-blind, Placebo- and Positive-controlled, Four-way Crossover Study to Assess the Effect of Single, Oral Dose of GSK1278863 on Cardiac Repolarization (Part B) in Healthy Volunteers

This study is being performed to comply with regulatory requirements that all new non-antiarrhythmic drugs must be assessed for potential effects on cardiac repolarization through electrocardiographic evaluation in a 'Thorough QT/ Corrected QT interval (TQT)' study. This will be a two part study, Part A will be an open-label, single oral dose study design in order to evaluate the pharmacokinetics, safety and tolerability of a 500 milligram (mg) dose of GSK1278863 and Part B will be a single-blind, randomized, placebo-controlled, single, oral dose, four-way crossover study design. Parts A and B will be conducted in healthy adult subjects with 12-lead electrocardiograms (ECGs), clinical laboratory safety tests, vital sign measurements, physical examinations, adverse event reports, and pharmacokinetic samples collected throughout the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK1278863 75 mg, GSK1278863 500 mg and Moxifloxacin 400 mg in people with Anaemia, run by GlaxoSmithKline 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 18 inclusion and 33 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 24 Jul 2018. 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?

Composite of pharmacokinetic (PK) parameters for GSK1278863 and its metabolites for Part A (time frame: Pre Dose, 0.25hour (h), 0.5h, 1h, 2h, 3h, 4h, 5h, 6h, 8h, 12h, 18h, and 24h post dose in each treatment period). The study lists 6 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 NCT02293148.

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 24 Jul 2018.
