Outcome Measures

Primary Outcomes (1)

  • Change from baseline in TNSS at each post-dose assessment time point (0 to 4 hours after a single dose).

    Onset of action of azelastine hydrochloride 0.15% nasal spray (Azelastine 0.15%) in treating the nasal symptoms of seasonal allergic rhinitis (SAR) induced by an allergen challenge in an Environmental Exposure Unit (EEU), measured by a difference from placebo in the change from baseline in patient -assessed instantaneous Total nasal symptom score (TNSS). 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. 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.

    0 to 4 hours post application

Secondary Outcomes (12)

  • Changes from baseline in TNSS at each post-dose assessment time point (0 to 4 hours after a single dose) at Visits 3, 6, and 9.

    0 to 4 hours post application

  • Changes from baseline in TOSS at each post-dose assessment time point (0 to 4 hours after a single dose) at Visits 3, 6, and 9.

    0 to 4 hours post application

  • Changes from baseline in T7SS at each post-dose assessment time point (0 to 4 hours after a single dose) at Visits 3, 6, and 9.

    0 to 4 hours post application

  • Change from baseline in individual symptom scores at each post-dose assessment time point (0 to 4 hours after a single dose) at Visits 3, 6, and 9.

    0 to 4 hours post application

  • Changes from baseline in TNSS for all assessment time-points together.

    0 to 4 hours post application

  • +7 more secondary outcomes
