Allergic Rhinitis Clinical Trial

Official title: An Open-label, Randomized, Parallel-Group, Multi-Site Study to Evaluate the Efficacy and Safety of Azelastine HCl-Fluticasone Propionate Nasal Spray 137-50 mcg/Spray in Perennial Allergic Rhinitis Patients

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of Azelastine HCl-Fluticasone propionate Nasal Spray 137-50 mcg/spray compared to Dymista™ in patients with perennial allergic rhinitis

Clinical Trial Description

This study is an open label, randomized, parallel-group study to evaluate the efficacy and safety of azelastine/fluticasone 137/50 mcg nasal spray, to Dymista™ nasal spray in perennial allergic rhinitis (PAR) patients.

An estimated 200 evaluable subjects are planned for this study. Subjects who are at least 20 years of age with PAR and meet the eligibility criteria will be eligible for this study.

There will be a 7-day washout period to establish a baseline, followed by a 28-day treatment period. All subjects who qualify after the washout period will be randomized to receive the test formulation of azelastine/fluticasone or Dymista™ during the treatment period, administered as one spray in each nostril twice daily for 28 days.

Subjects will self-score their symptoms twice daily (AM and PM, approximately 12 hours apart at the same times daily) throughout the washout period and the treatment period. During the treatment period, scoring should be made immediately prior to each dose to reflect the previous 12 hours (reflective scores). The 4 symptoms evaluated are: runny nose, sneezing, nasal itching, and congestion. Each of the symptoms will be scored on a scale of 0 to 3, with 0 indicating absent symptoms and 3 indicating severe symptoms (symptoms that are hard to tolerate; causes interference with activities of daily living and/or sleeping).

The primary endpoint is the difference in the mean change in reflective total nasal symptom scores (rTNSS) from baseline to the end of the treatment period. ;
