About this study

Official title: The Benefit of a Liraglutide-based Weight Management Alone or in Addition to Standard CPAP Therapy on Metabolic Function in Patients With Obstructive Sleep Apnoea (OSA) - an Explorative, Proof-of-concept Study

This is an explorative, proof-of-concept study exploring the potential therapeutic role of a Liraglutide-based weight loss regimen versus standard CPAP or the combination of both on metabolic parameters, blood pressure, endothelial function, coronary artery calcification, vascular inflammation and apnea/hypopnea index in non-diabetic patients with moderate to severe obstructive sleep apnea

Questions about this trial

What is this clinical trial studying?

A study testing Liraglutide (Saxenda) 6Mg/Ml Inj Pen 3Ml, Continuous positive airway pressure treatment and Liraglutide and CPAP in people with Sleep Apnea, Obstructive, run by St Vincent's University Hospital, Ireland at 1 site in Ireland.

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 11 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 18 Dec 2023. 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 Ireland. 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.

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?

Insulin resistance (time frame: 6 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 NCT04186494, 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 18 Dec 2023.
