About this study

Official title: Effectiveness of Oxymetazoline Added on Intranasal Steroid in the Treatment of Allergic and Nonallergic Rhinitis With Persistent Nasal Obstruction

Background Allergic rhinitis is a common health problem with a worldwide prevalence is 10-25%, and poses significant impact on the quality of life of the patients. In Thailand, the prevalence of allergic rhinitis in the general population is 13.5%, of which the frequency of allergic rhinitis increased from 23% to 38% in the children, and 61.9% in the graduate students. Despite intranasal steroid being the current first-line treatment of patients with allergic rhinitis, only 60% of patients achieve excellent control. Persistent nasal congestion is the major symptom which is difficult to control in these patients. Data are limited about efficacy and safety of the additional use of 0.05% intranasal oxymetazoline hydrochloride (OXY) for persistent nasal congestion that does not adequately respond to recommended doses of intranasal steroid (INS) and oral antihistamine(OAH).

Objective To determine the efficacy and safety of the additional use of OXY for persistent nasal congestion in allergic rhinitis or non-allergic rhinitis patients inadequately controlled by combination treatment with INS and OAH.

Methods The investigators performed a 6-week, randomized, double blind, placebo controlled, clinical trial in 50 patients with allergic rhinitis or non-allergic rhinitis whom inadequately controlled by combination treatment with INS and oral antihistamine (OAH). After an initial screening, qualified individuals were randomized into 2 groups including the treatment group and the control group. The treatment group received the INS (2 puffs in each nostril twice daily) and OAH (1 tablet once daily) plus OXY (2 puffs in each nostril twice daily) The control group received INS (2 puffs in each nostril twice daily) and OAH (1 tablet once daily) plus placebo (2 puffs in each nostril twice daily).

Read the detailed description

All participants will continue medications for 4 weeks, then stop using interventional medication and still take INS (2 puffs in each nostril twice daily) and OAH (1 tablet once daily) for 2 more weeks. Then, all participants will come for the last visit to see whether rebound nasal symptoms occur. Participants will be asked to record nasal symptom diary card, and nasal peak inspiratory flow. Rhinoconjunctivitis Quality of life Questionnaire (Rcq) will be recorded during visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • oxymetazolineDrug

    Also called Iliadin

    0.05% Oxymetazoline nasal sprays were commercially available.

  • Placebo nasal sprayDrug

    Placebo nasal spray has made by the local pharmaceutical company in thailand who commercially manufacture and sell 0.05% oxymetazoline nasal spray. The placebo contains the same ingredients as the drug except the active ingredient.

What is being measured

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

  1. Effectiveness of Oxymetazoline in the Treatment of Rhinitis With Persistent Nasal Obstruction

    Primary outcome measure is the nasal congestion score measuring by visual analog scale (VAS) ranging from 1-10 (0 = no symptom and 10 = the most severe symptom) compared between treatment group and controlled group.

    Measured: 6 weeks

Secondary outcomes (1)
  1. The Numbers of Subjects Who Developed Rhinitis Medicamentosa After Using Oxymetazoline

    Rhinitis medicamentosa is the rebound nasal congestion after prolonged use (>7 days) of topical nasal decongestant (eg. oxymetazoline). However, a previous study by Baroody FM et al (J Allergy Clin Immunol 2011;127:927-34) showed that using oxymetazoline together with intranasal steroid for 1 month did not increase rhinitis medicamentosa compared to placebo. So we give rhinitis patients in the treatment group with oxymetazoline and intranasal steroid for 1 month, then stop using oxymetazoline and come back for the last visit 2 weeks later to see which patients develop rebound nasal congestion (rhinitis medicamentosa).

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing oxymetazoline in people with Nasal Obstruction Present Finding, run by Mahidol University at 1 site in Thailand.

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 3 inclusion and 4 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 5 Jan 2015. 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 Thailand. 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?

Yes. Results are posted in the registry (first posted 5 Jan 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Effectiveness of Oxymetazoline in the Treatment of Rhinitis With Persistent Nasal Obstruction (time frame: 6 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 5 Jan 2015.
