Trial summary

The investigators wish to evaluate the effects of decongestants like oxymetazoline and the lessening of this effect with time called 'tolerance'. The investigators will demonstrate a reversal of this tolerance with nasal steroids i.e. the investigators will show that nasal steroids protect against tolerance. Read more about this study

About this study

Official title: A Proof of Concept Study to Evaluate if Concomitant Topical Intranasal Steroid Prevents Tolerance and Rebound Congestion Due to Regular Oxymetazoline in Persistent Allergic Rhinitis.

The investigators wish to evaluate the effects of decongestants like oxymetazoline and the lessening of this effect with time called 'tolerance'. The investigators will demonstrate a reversal of this tolerance with nasal steroids i.e. the investigators will show that nasal steroids protect against tolerance. This will tell us more on how the investigators can make this treatment effective and safe for patients suffering with allergic rhinitis.

Read the detailed description

Allergic rhinitis (AR) affects upto 25% of the worldwide population and is associated with asthma, with Scotland having the highest prevalence in the world. Nasal blockage is the main symptom of allergic rhinitis. Nasal blockage affects sleep quality and impairs daytime performance. It is a major cause of sickness absenteeism and has been shown to adversely affect quality of life. The most efficacious class of drugs for nasal blockage in AR are the nasal decongestants (sympathomimetics acting on alpha receptors which unblock the nose). These are available over the counter for routine use by people experiencing nasal blockage. Nasal steroids are the most effective drugs for overall symptoms of allergic rhinitis and are considered first line therapy by recent guidelines. There is widespread belief that prolonged use of decongestant sprays like oxymetazoline can result in a condition of decreased effectiveness called tolerance. It is thought that with time they lose their effectiveness and more and more medication is needed to achieve the same level of decongestion. Also it has been proposed that once stopped, the patient experiences rebound congestion. Long term users of nasal decongestants cannot get off their sprays because of this vicious cycle. These sprays act via stimulating the alpha adrenoreceptors in the nose. It is a poorly understood condition and the mechanism of action is unclear. What is also not clear is the time to onset of tolerance. From studies in the lung we know that tolerance in certain types of adrenoreceptors can be reversed by use of corticosteroids. We have also seen over many years of clinical practice that concomitant use of steroid sprays and decongestants prevents the onset of tolerance and rebound. Anecdotally, patients are often treated with this combination in clinic particularly during a common cold, hayfever season with high pollen counts and acute exacerbations. Therefore, we would like to conduct a proof of concept study to show that a combination nasal spray of decongestant and steroid protects against tolerance. We will also show protection against early rebound congestion. This will enable a new lease of life for allergic rhinitis sufferers, whose quality of life is most affected by nasal blockage and the absence of an effective long term drug strategy for it.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing oxymetazoline-fluticasone propionate and Oxymetazoline in people with Allergic Rhinitis and Tachyphylaxis, run by Brian J Lipworth at 2 sites in United Kingdom.

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 6 inclusion and 6 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: withdrawn, as of the sponsor's last update on 25 Oct 2016. 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 Kingdom. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

The primary endpoint will be the difference in peak PNIF response to incremental doses of Oxymetazoline [i.e. as a dose response] (time frame: Pre dose response, after 25, 50, 100, 200 mg/ml of oxymetazoline nasal spray). 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 NCT00846326, which also lists 15 linked publications.

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 25 Oct 2016.
