About this study

Official title: An Open-label, Randomized, Multi-center, Crossover Study to Observe the Effect of Once-daily Mirapex ER® and Twice-daily Mirapex ER® in Patients With Parkinson Disease

  1. In order to observe the benefit, side effects, and patient preference of Mirapex ER when used in once-daily (QD) or twice-daily (BID) dosing
  2. In order to estimate the conversion rate of dopamine agonists into Mirapex ER
Read the detailed description
  1. Study subjects : Parkinson disease who are on Requip or Mirapex and are considering to change into Mirapex ER
  2. Cross over study design:
  • Group 1: Once daily dose for 2 month then into BID in divided dose for 2 months
  • Group 2: BID in divided dose for 2 months then into QD dose for 2 months
  1. Dose adjustment may be done in the first 4 weeks.
  2. Compare the benefit, side effects, and patient preference between the QD vs BID dosing

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Mirapex ER in people with Parkinson's Disease, run by Seoul National University Hospital at 1 site in South Korea.

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: status not confirmed, as of the sponsor's last update on 24 Jan 2012. 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 South Korea. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Beom S Jeon, MD, PhD (82-2-2072-2876, brain@snu.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient preference (time frame: 4 months). 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 NCT01515774, which also lists 3 linked publications.

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 24 Jan 2012; AzTrials last refreshed its copy on 8 Nov 2026.
