About this study

Official title: The REmission of the Impulse Control Disorder and the Changes of the Neuropsychiatric Characteristics After Switching Into Levodopa/Carbidopa in Patients With Parkinson's Disease Who Have Developed Impulse Control Disorders Due to the Dopamine Replacement Therapy

The purpose of this study is to see whether the ICDs(Impulse Control Disorder) are improved and neuropsychiatric traits related to ICD are changed or not when switching dopamine agonist to levodopa/carbidopa in patients with Parkinson's disease who have been treated with dopaminergic medications.

Being tested
Levodopa/Carbidopa(200mg/50mg), Dopaminergic Agonists
Medical subject headings

What is being measured

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

  1. mMIDI(modified Minnesota Impulsive Disorders Interview)

    To evaluate the improvement of mMIDI(Korean version) score from the baseline to 12 weeks or LOCF(Last Observation Carried Forward)

    Measured: 12weeks

Secondary outcomes (1)
  1. Neuropsychiatric profile

    To evaluate the improvement of neuropsychiatric profiles from the baseline to 12 weeks or LOCF

    • Neuropsychological assessment
    • General cognitive status: K-Minimental status exam(K-MMSE)
    • Psychiatric profile:
    • Neuropsychiatric inventory (K-NPI)
    • Beck depression inventory (BDI)
    • Barratt impulsiveness scale (BIS)
    • Beck anxiety inventory (BAI)
    • State-trait anger expression inventory (STAXI)
    • Obsessive compulsive inventory (OCI)
    • Evaluation of global change:
    • Patient global impression of improvement (PGI-I)
    • Clinical global impression of improvement (CGI-I)

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levodopa/Carbidopa(200mg/50mg) and Dopaminergic Agonists in people with Impulse Control Disorder, run by Sandoz at 5 sites 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 6 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 10 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

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?

mMIDI(modified Minnesota Impulsive Disorders Interview) (time frame: 12weeks). 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 NCT01683253, 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 10 Mar 2021.
