About this study

Official title: Effect of Chronic Intermittent Nocturnal Hypoxia on Hepatic Drug Biotransformation in Children With Obstructive Sleep Apnea

The purpose of this research study is to determine the effect of chronic nighttime low oxygen saturations on selected body systems (liver) that break down drugs in children with obstructive sleep apnea syndrome (OSAS).

Read the detailed description

The purpose of this study is to determine the effect of chronic intermittent nocturnal hypoxia on selected hepatic drug-metabolizing enzyme systems in children with OSAS. The specific aims are to evaluate the activities of cytochrome P450 (CYP)1A2, N-acetyltransferase-2 (NAT-2), xanthine oxidase (XO)and CYP2D6 in children with OSAS and to determine the effect of OSAS treatment on the activities of these enzyme systems.

Questions about this trial

What is this clinical trial studying?

A study testing Dextromethorphan and Caffeine in people with Sleep Apnea, run by Virginia Commonwealth University at 2 sites in United States.

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 1 inclusion and 5 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 19 Mar 2009. 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 United States. 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?

Caffeine urinary molar ratio (time frame: Pre and post T&A). The study lists 2 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 19 Mar 2009.
