About this study

The investigators want to find new challenge test for Acetylsalicylic hypersensitivity / Aspirin hypersensitivity. The investigators suggest that this new test will be as efficient as the already established protocols in terms of sensitivity and specificity.

Read the detailed description

Hypersensitivity to Acetylsalicylic Acid or Aspirin (and other NSAIDS) is a condition that affects up to 2,5% of the population. Most cases are seen in a complex of such hypersensitivity with chronic eosinophilic rhinosinusitis with nasal polyposis and asthma. Despite research in finding a reliable in-vitro-test for the condition, challenge tests are still considered gold standard. So far oral, nasal, inhalation and intravenous routes of administration has been described in literature.

What is being measured

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

  1. Inspiratory nasal flow measured by Rhinomanometry

    Bilateral flow reduction >40% considered positive test.

    Measured: Within 45 min from challenge

  2. Expiratory nasal flow measured by Rhinomanometry

    Bilateral expiratory flow reduction >40% considered positive.

    Measured: Within 45 min from challenge

  3. Pulmonary forced expiratory volume in 1 second (FEV1)

    Reduction in FEV1 >20% is considered as positive test.

    Measured: Within 45 min from challenge

Secondary outcomes (3)
  1. Conjunctival symptoms

    0=no symptoms, 1=limited redness and / or itching, 2=conjunctival redness and /or itching / swelling or bullae within 5 minutes from testing.

    Value 1 and 2 is considered positive if unilateral.

    Measured: Within 45 days from challenge

  2. Nasal symptoms

    Rhinorrhea, congestion and sneezing is considered as positive test.

    Measured: Within 45 minutes from challenge

  3. Bronchial and laryngeal symptoms

    Bronchospasm. tight chest, wheezing or laryngospasm is considered as positive test.

    Measured: Within 45 minutes from challenge

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 2 inclusion and 8 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 13 Sep 2012. 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 Norway. 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.

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 Gregor Bachmann-Harlidstad, MD, PhD (0047 02900 (central), Gregor.Bachmann-Harlidstad2@ahus.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Inspiratory nasal flow measured by Rhinomanometry (time frame: Within 45 min from challenge). The study lists 3 primary outcomes in all. 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 NCT01681615, which also lists 25 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 13 Sep 2012.
