What is being measured

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

  1. Change in Patient-assessed Instantaneous Total Nasal Symptom Score (TNSS) From Baseline Compared to Placebo

    FDA guideline defines onset of action as the first time point after initiation of treatment when the product demonstrated a greater change from baseline compared to placebo which proved durable.

    In this study, the first significant difference to placebo of TNSS was observed at 5 minutes time point (= onset of action).

    The TNSS is comprised of 4 symptoms from the nose, each scored on a scale of 0 to 3 (0 = none and 3 = severe). The sum of the TNSS contributes to a score ranging from 0 - 12.

    Measured: 0 to 4 hours post application

Secondary outcomes (1)
  1. Change in Patient-assessed Instantaneous Total Ocular Symptom Score (TOSS) From Baseline Compared to Placebo

    FDA guideline defines onset of action as the first time point after initiation of treatment when the product demonstrated a greater change from baseline compared to placebo which proved durable.

    In this study, the first significant difference to placebo of TOSS was observed at 10 minutes time point (= onset of action).

    The TOSS is comprised of 3 symptoms from the eyes, each scored on a scale of 0 to 3 (0 = none and 3 = severe). The sum of the TOSS contributes to a score ranging from 0 - 9.

    Measured: 0 to 4 hours post application

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Treatment A (Dymista): Fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray at Visit 3 and Treatment A (Dymista): Fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray at Visit 5 in people with Seasonal Allergic Rhinitis, run by MEDA Pharma GmbH & Co. KG at 1 site in Canada.

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 15 inclusion and 24 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 23 Mar 2023. 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 Canada. 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. 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 23 Mar 2023). 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?

Change in Patient-assessed Instantaneous Total Nasal Symptom Score (TNSS) From Baseline Compared to Placebo (time frame: 0 to 4 hours post application). 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 23 Mar 2023.
