About this study

Official title: An Open Label Extension Study With REQUIP PR for Subjects From Study ROP111528

This open label extension study allows assessment of the long term safety profile of REQUIP PR in subjects who have completed 24 weeks of randomised treatment in study ROP111528.

Subjects must not have a break in study medication between completing the feeder study and entering extension study, treatment must be continuous.

Subjects will be dispensed down-titration medication at the study completion/early withdrawal visit and should be scheduled to return for a follow up visit 4 to 14 days after the last dose of study medication.

Being tested
Requip PR
Medical subject headings
Parkinson Disease

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Requip PRDrug

    Eligible patients will be dispensed medication to uptitrate their REQUIP PR dose (2, 4, 6, 8mg respectively) during the first 4 weeks of treatment. During the 24 week treatment phase, the subjects dose will be adjusted according to the recommended schedule to achieve symptomatic control.

What is being measured

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

  1. Number of Participants With the Indicated Types of Adverse Events (AEs) and Serious Adverse Events (SAEs) During the On-Treatment Phase (Comprised of the Open-label Treatment Phase and the Down-titration Phase)

    AE=any untoward medical occurrence (UMO), temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP. SAE=any UMO that, at any dose, results in death, is life threatening, requires hospitalization/prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomoly/birth defect. The Investigator determined if an AE/SAE was related to investigational product. Medical/scientific judgment was used to determine whether SAE reporting was appropriate in situations in which an event may not have met the SAE definition.

    Measured: From the start of treatment (Baseline) up to Week 25

  2. Number of Participants With the Indicated Adverse Events Related to Investigational Product During the On-treatment Phase

    An adverse event is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. The Investigator determined if an AE/SAE was related to investigational product. The On-Treatment Phase is comprised of the Open-label Treatment Phase and the Down-titration Phase.

    Measured: From the start of treatment (Baseline) up to Week 25

  3. Number of Participants With an Adverse Event During the Follow-up Phase

    AE=any untoward medical occurrence (UMO), temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP. SAE=any UMO that, at any dose, results in death, is life threatening, requires hospitalization/prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomoly/birth defect. The Investigator determined if an AE/SAE was related to investigational product. Medical/scientific judgment was used to determine whether SAE reporting was appropriate in situations in which an event may not have met the SAE definition.

    Measured: 4- to 14-day Follow-up Phase, beginning after the date of the last dose of down-titration medication (up to and during Study Weeks 26 and 27)

  4. Number of Participants With the Indicated Adverse Events During the Follow-up Phase

    An adverse event is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. In addition to the data recorded at the follow-up visit, SAEs occurring up to and including 2 days after the last dose of down-titration medication are included in the Follow-up Phase.

    Measured: 4- to 14-day Follow-up Phase, beginning after the date of the last dose of down-titration medication (up to and during Study Weeks 26 and 27)

  5. Number of Participants With the Indicated Adverse Events Related to Investigational Product During the Follow-up Phase

    An adverse event is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. The Investigator determined if an AE/SAE was related to investigational product. In addition to the data recorded at the follow-up visit, SAEs occurring up to and including 2 days after the last dose of down-titration medication are included in the Follow-up Phase.

    Measured: 4- to 14-day Follow-up Phase, beginning after the date of the last dose of down-titration medication (up to and during Study Weeks 26 and 27)

Secondary outcomes (2)
  1. Mean Gambling Symptom Assessment Scale (G-SAS) Score at Week 24

    The G-SAS is a reliable and valid self-reported measure of gambling symptoms. It is comprised of twelve questions aimed at evaluating gambling symptoms; each item is scored on a 5-point scale from 0 (no symptoms) to 4 (extreme symptoms). The total score ranges from 0 to 48, where 0=least severe and 48=most severe.

    Measured: Week 24

  2. Mean Change From Baseline in the Gambling Symptom Assessment Scale (G-SAS) Score at Week 24

    The G-SAS is a reliable and valid self-reported measure of gambling symptoms. It is comprised of twelve questions aimed at evaluating gambling symptoms; each item is scored on a 5-point scale from 0 (no symptoms) to 4 (extreme symptoms). The total score ranges from 0 to 48, where 0=least severe and 48=most severe. Change from Baseline is calculated as the value at Week 24 minus the Baseline value.

    Measured: Baseline and Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Requip PR in people with Parkinson Disease, run by GlaxoSmithKline at 18 sites in China.

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 7 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 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in China. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Dec 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With the Indicated Types of Adverse Events (AEs) and Serious Adverse Events (SAEs) During the On-Treatment Phase (Comprised of the Open-label Treatment Phase and the Down-titration Phase) (time frame: From the start of treatment (Baseline) up to Week 25). The study lists 5 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 NCT01536574, 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 13 Aug 2018.
