No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
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.
