Trial summary

GSK729327 is a selective positive allosteric modulator of AMPA-type ionotropic glutamate receptors, exhibiting equivalent potency at all AMPA receptor subtypes. On the basis of preclinical studies it is expected that this compound will improve cognitive measures in schizophrenic patients with acceptable safety. Read more about this study

About this study

Official title: Single-Blind, Randomised, Placebo-Controlled Two-Part Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Oral Escalating Doses and Repeat Doses of GSK729327 in Healthy Volunteers

GSK729327 is a selective positive allosteric modulator of AMPA-type ionotropic glutamate receptors, exhibiting equivalent potency at all AMPA receptor subtypes. On the basis of preclinical studies it is expected that this compound will improve cognitive measures in schizophrenic patients with acceptable safety. This is a First Time in Human Study (FTIH) to assess the safety, tolerability, pharmacokinetics and preliminary pharmacodynamics of GSK729327 in healthy volunteers. The study will be conducted in 2 parts, with single doses being explored in Part A and multiple doses over 28 days in Part B. Part A will be a single blind, placebo controlled, single oral dose, dose-rising cross-over study in healthy male volunteers. Subjects will be randomized into two cohorts with an alternate panel design. There will be up to nine dosing sessions in total in order to investigate up to 7 different doses. The initial dose will be 0.25 mg and subsequent doses will be determined based on the pharmacokinetic and safety results from the previous dose. Part B will be a randomised, single blind, placebo-controlled, parallel group study of repeat oral dosing of GSK729327. Up to 4 cohorts of 15 (12 subjects receiving active dose and 3 subjects receiving placebo) healthy male and females of (non-childbearing potential) volunteers will be enrolled in Part B.

What is being measured

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

  1. Safety and tolerability endpoints of AEs; EEG; ECGs; neurological assessments; vital signs and clinical laboratory values.Part A PK parameters of Cmax,AUC,t1/2,Tmax,Ae(0-t).Part B PK parameters of Cmax,Tmax,t1/2,AUC and accumulation ratio.

    Measured: throughout the study

Secondary outcomes (1)
  1. Pharmacodynamic effects on Bond-Lader,Body Sway and EEG and the relationship of plasma levels of GSK729327 with pharmacodynamic parameters.Part B will also look atcognitive function,Polysomnography and LSEQ.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK729327 in people with Schizophrenia, run by GlaxoSmithKline at 2 sites in 2 countries.

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 5 inclusion and 18 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 15 Oct 2010. 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 Germany, United Kingdom. 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. Some participants in this study may receive a placebo. 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?

Safety and tolerability endpoints of AEs; EEG; ECGs; neurological assessments; vital signs and clinical laboratory values.Part A PK parameters of Cmax,AUC,t1/2,Tmax,Ae(0-t).Part B PK parameters of Cmax,Tmax,t1/2,AUC and accumulation ratio. (time frame: throughout the study). 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 15 Oct 2010.
