About this study

Official title: An Open Label, Repeat Dose, Dose Escalation Study Conducted in RLS Patients to Characterize Pharmacokinetics and Food Effect of Ropinirole Controlled Release for RLS

This study in RLS patients is designed to assess the affect food has on the absorption, distribution, metabolism and excretion of ropinirole (by dosing some patients in the fasted state and other patients following a high-fat breakfast), and to assess the difference in absorption, distribution, metabolism and excretion of ropinirole if patients are given two 3mg ropinirole tablets versus one 6mg tablet.

What is being measured

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

  1. Ropinirole AUC (area under the plasma concentration-time curve) over the dosing interval Ropinirole maximum plasma concentration

    Measured: dosing interval

Secondary outcomes (1)
  1. Time to attain the maximum plasma concentration Time taken for ropinirole concentration to fall to half initial value Incidence of adverse events Vital signs, ECG and clinical laboratory data As above, but for ropinirole metabolites

    Measured: Time taken for ropinirole concentration to fall to half initial value

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ropinirole in people with Restless Legs Syndrome, 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 4 inclusion and 10 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 13 Oct 2017. 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, South Africa. 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?

Ropinirole AUC (area under the plasma concentration-time curve) over the dosing interval Ropinirole maximum plasma concentration (time frame: dosing interval). 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 13 Oct 2017.
