About this study

Official title: A Single Blind, Double Dummy, Placebo Controlled, Randomized, 2 Period Crossover Study to Assess the Relative Bioavailability of a 120mg Tablet Compared to Two 60 mg SB-773812 Tablets in Healthy Volunteers

Study to compare PK of a new 120mg tablet with two 60mg tablets. This is required because we plan to have only single tablets administered in the later phase clinical trials but we have not had a 120mg strength before. As this is a new previously untested strength we need to ensure that the PK is similar to that achieved using 2x60mg before we start a large manufacturing campaign and before we administer to a large number of patients. The study is planned to consist of a single part, with two dosing periods, periods 1 and 2 consisting of 18 subjects. There will be 20 days washout between each dose. Initially 4 subjects will be given a single oral dose of 120 mg SB-773812 and 2 will be given placebo. If 120mg SB-773812 is well tolerated in the first four volunteers, the remaining 12 subjects will be dosed. If the 120mg single oral dose in the first 4 subjects is poorly tolerated, the study will be stopped. Subjects will return to the centre for follow-up 14 to 21 days after the final dose.It is expected that the total duration of the study should be approximately 11 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SB- 773812 60 mg and SB- 773812 120 mg in people with Schizophrenia, run by GlaxoSmithKline at 1 site in United Kingdom.

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 16 inclusion and 14 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 Aug 2017. 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 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. 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?

Blood sampling over a period 336 hrs post SB773812 dosing in both dosing sessions. (time frame: 336 hrs post SB773812 dosing). 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 8 Aug 2017.
