The investigators hypothesize that treatment with QNASL will reduce nasal mucosal inflammation induced by the allergy season and prevent the changes in the microbiome caused by the allergy season.

Condition Intervention Phase
Seasonal Allergic Rhinitis Drug: QNASL Drug: Placebo nasal spray Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Allergic Rhinitis Changes the Sinus Microbiome

Further study details as provided by University of Chicago:

Primary Outcome Measures:
  • Change in sinonasal microbiome during the seasonal allergy exposure [ Time Frame: 2 weeks following treatment in the allergy season ]
    Sinonasal microbiome will be examined prior to allergy season and 2 weeks after treatment with QNASL or placebo in the allergy season

Secondary Outcome Measures:
  • Symptoms of sneezing, rhinitis, nasal congestion and nasal itching [ Time Frame: 2 weeks ]
    Symptom scores will be recorded by subjects twice daily during the trial. Subjects report four symptoms: sneezing, rhinorrhea, nasal congestion, and nasal itching on a scale from 0 to 3 (0= no symptoms, 1= mild symptoms, 2= moderate symptoms, 3= severe symptoms).

Other Outcome Measures:
  • Rhinoconjunctivitis quality-of-life questionnaire (RQLQ) [ Time Frame: Following 2 weeks of treatment with study drug or placebo ]
    Quality of life will be assessed with the self-administered rhinoconjunctivitis quality-of-life questionnaire (RQLQ) as described and validated by Juniper and colleagues.

  • Nasal eosinophilia [ Time Frame: Following 2 weeks of treatment with study drug or placebo ]
    Total counts of eosinophils recovered from lavages prior to and following treatment
