What is being measured

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

  1. Total Nasal Symptom Score (TNSS)

    The Total Nasal Symptom Score (TNSS) is the sum of scores for each of nasal congestion, sneezing, nasal itching, and rhinorrhea using a four point scale (0-3), where 0 indicates no symptoms, a score of 1 for mild symptoms that are easily tolerated, 2 for awareness of symptoms which are bothersome but tolerable and 3 is reserved for severe symptoms that are hard to tolerate and interfere with daily activity. TNSS is calculated by adding the score for each of the symptoms to a total out of 12. TNSS was assessed daily and summed over 14 days; thus, the total score ranges from 0 to 168, with higher scores indicating a worse outcome.

    Measured: Two weeks following initiation of treatment

  2. Change in RQLQ Score From Baseline to Two Weeks

    The Rhinoconjunctivitis Quality Of Life Questionnaire (RQLQ) is a self-administered disease-specific health-related quality of life instrument that measures the functional impairments that are most troublesome to adult patients as a result of their seasonal or perennial rhinoconjunctivitis of either allergic or non-allergic origin. There are 28 items each asking about symptoms during the previous week. Seven domains of activity limitation are included: activities (3 "patient-specific") limitation, sleep problems (3 items), nose symptoms (4 items), eye symptoms (4 items), non-nose/eye symptoms (7 items), practical problems (3 items) and emotional function (4 items)). Each item is reported using a 7-point scale (0 = not impaired at all, 6 = severely impaired), and a total score is calculated by averaging over all items (range 0-7). Higher scores reflect lower quality of life.

    Measured: Two weeks following initiation of treatment

  3. Change in Percent Eosinophils From Baseline to Two Weeks

    The percentage of nasal eosinophils recovered from nasal lavage was assessed at baseline and after two weeks of treatment.

    Measured: Two weeks following initiation of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing QNASL in people with Seasonal Allergic Rhinitis, run by University of Chicago 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 3 inclusion and 10 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 9 Oct 2020. 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?

Yes. Results are posted in the registry (first posted 9 Oct 2020). 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?

Total Nasal Symptom Score (TNSS) (time frame: Two weeks following initiation of treatment). 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?
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 9 Oct 2020.
