About this study

Official title: Effect of Oxymetazoline Hydrochloride in Combination With Fluticasone Propionate on the Apnea Hypopnea Index (AHI) in Subject With Persistent Nasal Congestion and Mild Obstructive Sleep Apnea. A Double Blinded Placebo Controlled, Crossover Prospective Trial.

The addition of intranasal oxymetazoline for two weeks to already instituted optimal doses of intranasal fluticasone propionate will decrease the total number of obstructive apneas and hypopneas per hour of sleep in subjects with perennial allergic or non-allergic rhinitis and mild obstructive sleep apnea who have persistent nasal congestion despite maximum doses of NGCS.

Read the detailed description

To evaluate the effectiveness of the addition of intranasal oxymetazoline to ongoing optimal doses of intranasal fluticasone propionate on the apnea/hypopnea index (AHI) in subjects with persistent nasal congestion and mild obstructive sleep apnea secondary to perennial allergic or non-allergic rhinitis despite treatment with the recommended doses of NGCS. The NOX T3 portable sleep monitor will be used to measure the AHI.

  1. The Flow Sensor, as part of the NOX T3 portable monitor, will be used to assess flow limitation of the upper airway through calculation of the flattening index, a marker of upper airway resistance.
  2. The Congestion Quantifier 7 (CQ7) questionnaire will be used to assess for an improvement in nasal congestion based on symptoms from the prior week.
  3. The Nasal Congestion Visual Analog Scale (VAS) will be used to identify the changes in the severity of nasal congestion on a day to day basis.
  4. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) will be used to assess the impact of perennial rhinitis and nasal congestion on activities of daily living.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The proportion of subjects demonstrating a 50% reduction in the apnea hypopnea index after treatment with oxymetazoline hydrochloride and fluticasone propionate for 2 weeks.

    This study is a double blinded, placebo control, cross over prospective trial. Each subject will complete the two arms in this study. The subject will be randomized to receive either oxymetazoline hydrochloride plus fluticasone propionate initially or placebo plus fluticasone propionate and complete treatment for a total of 2 weeks respectively. At the completion of each arm (prior to visit 3 and visit 5), the apnea hypopnea index will be measured.

    Measured: 2 weeks

Secondary outcomes (1)
  1. The proportion of subjects demonstrating an improvement in moderate to severe upper airway flow limitation as measured by a change in the flattening index after treatment with oxymetazoline hydrochloride and fluticasone propionate for 2 weeks.

    This study is a double blinded, placebo control, cross over prospective trial. Each subject will complete the two arms in this study. The subject will be randomized to receive either oxymetazoline hydrochloride plus fluticasone propionate initially or placebo plus fluticasone propionate and complete treatment for a total of 2 weeks respectively. At the completion of each arm (prior to visit 3 and visit 5), upper airway flow limitation will be measured by a change in the flattening index from a value of ≥ 0.01 to 0.14 (moderate to severe airflow limitation) to a value of 0.15 - 0.3+ (mild airflow limitation to completely open upper airway).

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Oxymetazoline Hydrochloride in people with Sleep Apnea and Chronic Nasal Congestion, run by University of South Florida at 1 site 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 7 inclusion and 23 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: looking for participants now, as of the sponsor's last update on 24 Jan 2025. 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 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. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Catherine R Smith (813-631-4024 ext. 207, catherinesmith@health.usf.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The proportion of subjects demonstrating a 50% reduction in the apnea hypopnea index after treatment with oxymetazoline hydrochloride and fluticasone propionate for 2 weeks. (time frame: 2 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 24 Jan 2025.
