About this study

Official title: Effect of Continuous Positive Airway Pressure (CPAP) on Cardiovascular Biomarkers in Patients With Obstructive Sleep Apnea.

CPAP, the standard treatment for Obstructive sleep apnea syndrome (OSAS) that reduces sleep fragmentations and neurocognitive deficit in OSAS may also have a key role in reduction of cardiovascular, mortality risks in the same patients.

Read the detailed description

Obstructive sleep apnea (OSA) is a condition in which there is collapse of the upper airway during sleep, as a result of which there is a decrease or complete cessation of airflow. This leads to repeated episodes of hypoxia during sleep and sleep fragmentation. It is a highly prevalent though under-recognized clinical problem.There is increasing evidence that inflammation plays important role in development of cardiovascular complications in patients with OSA.

Continuous positive airway pressure (CPAP) is the standard treatment for OSA with significant symptoms.However, it is a costly treatment option and poor compliance is an important limiting factor. CPAP treatment has been shown to improve the daytime somnolence and neurocognitive function in people with OSAS. However, its effect on cardiovascular biomarkers in people with OSAS has not been satisfactorily assessed.

This study aims to assess the effect of CPAP treatment on cardiovascular biomarkers in OSA.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing AutoSet Spirit--Wash--Modified-AutoSet Spirit and Modified-AutoSet Spirit--Wash-AutoSet Spirit in people with Obstructive Sleep Apnea, run by All India Institute of Medical Sciences at 1 site in India.

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 13 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 Jun 2013. 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 India. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Surendra K Sharma, MD, Ph.D (91-11-26594415, sksharma@aiims.ac.in), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of CPAP therapy on blood pressure (time frame: 7 months). The study lists 5 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 24 Jun 2013.
