DYmista NAsal Spray in CHInese Patients (DYNAS-CHI)

Multicentre, Randomized, Double-blind, Parallel Group Phase III Study to Assess Efficacy and Safety of Dymista® Compared to Azep® and Flixonase® Nasal Sprays in the Treatment of Chinese Patients With Allergic Rhinitis/Rhinoconjunctivitis

This study is a phase III clinical study to assess the efficacy and safety of Dymista® Nasal Spray in comparison to Azep® nasal spray and Flixonase® nasal spray in Chinese patients aged ≥ 12 years with moderate-to-severe allergic rhinitis/rhinoconjunctivitis.

Study Overview

• Status: Completed
• Conditions: Allergic Rhinitis
• Intervention / Treatment: Drug: Azelastine Hydrochl./Fluticasone Prop. 0.137/0.05 MG/ACTUAT; Drug: Azelastine Hydrochloride 0.137 MG/ACTUAT; Drug: Fluticasone Propionate 0.05 MG/ACTUAT

Detailed Description

This is a multicentre, randomized, active controlled prospective clinical trial in adult and adolescent patients with AR (seasonal and/or perennial), who have moderate-to-severe symptoms (rhinitis/ rhinoconjunctivitis), based on the Allergic Rhinitis and its Impact on Asthma (ARIA) 2008 Guidelines. The study consists of a 3 to 7-day Lead-in Period during which patients must meet a minimum symptom severity score to be eligible for the Treatment Period. All patients will start the Lead-in Period straight after Screening Visit as soon as in/exclusion criteria are fulfilled. The Lead-in Period will be followed by a 14-day double-blind Treatment Period. At some time point during the study, patients will receive Placebo and Dymista® nasal spray or Azep® nasal spray or Flixonase® nasal spray, 1 spray per nostril twice daily according to randomization. On the first day of the Lead-in Period patients must meet study inclusion/exclusion criteria and have a sufficient AR symptom score to qualify for entry. Qualified patients will be requested to keep a Diary of nasal and ocular symptoms throughout the study period. Additionally, patients will be requested to complete the Adult Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and EuroQoL 5D questionnaire (EQ-5D) on Day 1, Day 8 and Day 15. Both Questionnaires will be completed by adult patients only.

   • Sleep disturbance.
   • Impairment of daily activities, leisure and/or sport.
   • Impairment of learning or work.
   • Troublesome symptoms.
4. Patients must have moderate-to-severe rhinitis or rhinoconjunctivitis and monotherapy with either intranasal antihistamine or glucocorticoid is not considered sufficient at the discretion of the Investigator and/or designee.
5. Conducting the Lead-in Period according to the protocol.
6. Willing and able to comply with the study requirements.
7. At least a 2-year history of AR (seasonal and/or perennial) during the same time of year as the scheduled study time.
8. The presence of Immunoglobulin E (IgE)-mediated hypersensitivity to one or more aeroallergens present in current patient environment, confirmed by a positive response to an established standard diagnostic test at the site within the last year (before randomization).
9. General good health and free of any disease or concomitant treatment that could interfere with the interpretation of the study results as determined by the Investigator or the sponsor's medical officer.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Combined 12-hour rTNSS (AM + PM)	Total nasal symptom score (TNSSS) is a sum of 4 individual nasal symptom scores: nasal itching, runny nose, congestion and sneezing. Each nasal symptom will be assessed according to a 4-ponit scale (0 = no, 1 = mild, 2 = moderate, 3 = severe symptom); thus, each TNSS will be in the range from 0 (no symptoms at all) to 12 (all 4 symptoms are severe) and the combined 12-hour reflective TNSS (morning + evening) will be in the range of 0 to 24 accordingly	14 days
