About this study

Official title: Varenicline, a Partial Nicotinic Receptor Agonist for the Treatment of Excessive Daytime Sleepiness in Parkinson's Disease: a Placebo-controlled Cross-over Pilot Study

The effect of varenicline, an alpha4beta2 nicotinic receptor partial agonist on excessive daytime sleepiness in Parkinson's disease will be studied in a randomized, double blind, placebo-controlled clinical trial with a within-subject crossover design.

Read the detailed description

Sleep disturbances are common in Parkinson's disease and include excessive daytime sleepiness that has been reported in up to 50% of patients. Relatively little therapeutic research has addressed the problem of excessive daytime sleepiness and current treatment is largely aimed at reducing the dose of dopaminergic medication while trying to maintain sufficient motor control which unfortunately often fails. Apart from degeneration of dopaminergic neurons, a decrease in cholinergic projections to the brain arousal areas may be at least partly responsible for the occurrence of excessive daytime sleepiness in Parkinson's disease. Smoking in narcoleptic patients diminishes sleep attacks and excessive daytime sleepiness , thus one may hypothesize that nicotinergic stimulation of the brain arousal areas may improve excessive daytime sleepiness in Parkinson's disease. Therefore the effect of varenicline, an alpha4beta2 nicotinic receptor partial agonist, on excessive daytime sleepiness in Parkinson's disease will be studied in a placebo-controlled cross-over study.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Varenicline in people with Parkinson's Disease, run by Amsterdam UMC, location VUmc at 2 sites in Netherlands.

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: stopped early, as of the sponsor's last update on 9 Oct 2018. 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 Netherlands. 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. Some participants in this study may receive a placebo. 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 was stopped early (reason given: insufficient patient enrollment, insufficient funds for completion). Results are not available in the source record.

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?

Daytime sleepiness (time frame: 4 weeks). 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 9 Oct 2018.
