Study population: The study cohorts of interest will be identified from the most recent datacut of the IHCIS database. Individuals with one or more prescriptions of levodopa between 1st July 2004 and 30th June 2010 will be included. The date of the first prescription of levodopa in the study time period is defined as the INDEX DATE. All individuals must be on the database with medical and pharmacy benefit for at least 6 months prior to the INDEX DATE. All individuals must have one or more diagnosis codes for Parkinson's disease within the 6 months prior or 6 months post INDEX DATE. Individuals will be excluded if age is <20 years on the INDEX date. Individuals will also be excluded if they have a previous levodopa prescription prior to the INDEX date as only new users of levodopa are of interest.

About this study
Official title: Background Incidence of Cardiovascular Ischaemic Events in Treated Parkinson's Disease Patients in the Impact Database
Cardiovascular (CV) disease is a common comorbidity of Parkinson's disease (PD). The background incidence rate of CV events in a levodopa-treated PD population was assessed to better understand these comorbidities in the PD population. One objective of the study is to identify a population of prevalent PD patients with incident levodopa use within the years 2004-2010 on the Integrated Health Care Information Services (IHCIS) database. The second objective is to report the incidence of CV events overall and during intervals 0-6, 6-12 and 12-18 months after first prescription of levodopa among all new levodopa users.

All individuals must have one or more diagnosis codes for Parkinson's disease within the 6 months prior or 6 months post INDEX DATE. Individuals will be excluded if age is <20 years on the INDEX date. Individuals will also be excluded if they have a previous levodopa prescription prior to the INDEX date as only new users of levodopa are of interest.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Event and Parkinson Disease, run by GlaxoSmithKline.
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 3 inclusion and 2 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 16 May 2017. Status can change between updates, so confirm with the study contact before making plans.
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.
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?
Occurrence of CV events during first 6 months (time frame: 0-6 months after first prescription of levodopa). The study lists 4 primary outcomes in all. 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 16 May 2017.
