Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is designed to evaluate the efficacy, safety, and tolerability of PL-14 Allergy Blocker compared to saline spray in adults with Seasonal Allergic Rhinitis (SAR). PL-14 Allergy Blocker is a non-pharmacological, drug-free intranasal mucoadhesive hydrogel designed to form a mechanical barrier on the nasal mucosa and reduce contact between airborne allergens and the nasal lining. This is a prospective, randomized, single-blind, multi-center clinical investigation in up to 120 participants at up to 8 sites in the United States. Eligible participants with a history of seasonal allergic rhinitis will be randomized in a 1:1 ratio to receive either PL-14 Allergy Blocker or Ayr® Saline Nasal Mist for up to 30 days. The study will evaluate the effect of PL-14 Allergy Blocker on nasal allergy symptoms, quality of life, rescue medication use, and symptom-free days. Safety and local tolerability assessments will also be performed throughout this study period.
