About this study

Official title: A Phase I Non-Randomized Multi Cohort, Open Label, Bridging Study to Evaluate the Pharmacokinetics, Safety and Tolerability of GSK557296 in Healthy Women Volunteers After Single and Repeat Dosing

GSK557296 is being studied in women for the indication of enhanced embryo and or blastocyst implantation in women undergoing IVF treatment. This study will be the first dosing experience with this compound in women. It is important to characterize the pharmacokinetics of GSK557296 in women to determine the most appropriate doses and dosing regimens for future clinical studies. Understanding the pharmacokinetics of GSK557296 in women will also enable more accurate characterization of any exposure-response relationship in future studies.

Two previous studies with GSK557296 were conducted in men with oral doses ranging from 10 milligram (mg) to 200 mg. GSK557296 is being studied in women for the indication of enhanced embryo and or blastocyst implantation in women undergoing IVF treatment. This is a bridging study to characterize the pharmacokinetics of GSK557296 in women to determine the most appropriate doses and dosing regimens for future clinical studies.

This is a non-randomized, open label, adaptive design study in healthy female volunteers. A maximum total of 48 subjects, will participate in different cohorts. Subjects in Cohort 1 will receive 10 mg single dose followed by repeat dose. A one week break will occur to allow for analysis of the PK data, prior to starting the second Cohort. Subjects in Cohort 2 will receive 150 mg single dose followed by repeat dose. Cohort 3 and Cohort 4 were adaptive based on the requirement of additional doses to be studies after PK data will be analyzed from each of the first 2 cohorts.

What is being measured

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

  1. Composite of PK parameters of 20 mg GSK557296 following single and repeat oral dosing

    From the plasma concentration-time data, the following PK parameters will be determined: maximum observed plasma concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-time curve [AUC(0-t) and AUC(0-infinity)], and apparent terminal phase half-life (t1/2). AUC(0-infinity) or AUC(0-τ) and Cmax following single and repeat doses may be used for assessment of dose proportionality.

    Measured: 7 days

  2. Composite of PK parameters of 150 mg GSK557296 following single and repeat oral dosing

    From the plasma concentration-time data, the following PK parameters will be determined: maximum observed plasma concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-time curve [AUC(0-t) and AUC(0-infinity)], and apparent terminal phase half-life (t1/2). AUC(0- infinity) or AUC(0-τ) and Cmax following single and repeat doses may be used for assessment of dose proportionality.

    Measured: 14 days

  3. Safety and tolerability of GSK557296 following single and repeat dosing

    Safety and tolerability parameters assessments include adverse events, clinical laboratory, ECG, vital signs, and concurrent medication

    Measured: up to 49 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK557296 10 mg, GSK557296 150 mg and GSK557296 dose 3 in people with Embryo Transfer, 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 6 inclusion and 13 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 7 Jun 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 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 PK parameters of 20 mg GSK557296 following single and repeat oral dosing (time frame: 7 days). The study lists 3 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 NCT01669083, which also lists 1 linked publication.

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 7 Jun 2017.
