A Study Evaluating the Safety and Effectiveness of a Nasal Spray to Treat Seasonal Allergies

• Change From Baseline in 12 Hour Instantaneous Total Nasal Symptom Score (iTNSS) [ Time Frame: day 1 to14 ] [ Designated as safety issue: No ]

  change from baseline in 12-hour instantaneous ( how do you feel now) total nasal symptom score (iTNSS)consisting of nasal congestion,runny nose, itchy nose and sneezing scored twice daily (AM and PM) in diary cards for the entire 14 day study period.

  The measurement scale is 0 to 24.A reduction in symptom severity score is indicated by a negative value.A greater negative value is suggestive of improvement.

• Change From Baseline in Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) [ Time Frame: day 1 to day 14 ] [ Designated as safety issue: No ]
  adult Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scored at day 1(baseline) and at day 14.The scale is measured from a value of 0 to 24. A negative number corresponds to a change from baseline measurement. An increased negative number is suggestive of improvement.

• Change from baseline in 12 hour instantaneous total nasal symptom score [ Time Frame: 14-days ] [ Designated as safety issue: No ]
• Onset of action assessment [ Time Frame: 4 hours ] [ Designated as safety issue: No ]
• Change from baseline in Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) [ Time Frame: 14 Days ] [ Designated as safety issue: No ]
• Nasal Examinations [ Time Frame: 14 days ] [ Designated as safety issue: Yes ]

The purpose of this study is to determine if two allergy medications (formulated azelastine and fluticasone product) are more effective than placebo or either medication alone (azelastine or fluticasone)

This will be a Phase III, randomized, double-blind, placebo-controlled, parallel-group study in subjects with moderate-to-severe seasonal allergic rhinitis (SAR). The study will begin with a 7-day, single-blind, placebo lead-in period (Day -7 to Day 1). Subjects will be instructed to take placebo lead-in medication twice daily (1 spray per nostril), approximately every 12 hours. On Day 1, subjects who satisfy the symptom severity requirements and continue to meet all of the study inclusion/exclusion criteria will be randomized in a 1:1:1:1 ratio to receive 1 spray per nostril twice daily of MP29-02, azelastine hydrochloride, fluticasone propionate, or placebo nasal spray.

Efficacy will be assessed by the change from baseline in the subject-reported 12-hour reflective Total Nasal Symptom Score (TNSS). On Days 1 through 14, subjects will rate the instantaneous and reflective TNSS symptoms of sneezing, nasal congestion, runny nose, and nasal itching; the instantaneous and reflective total ocular symptom score (TOSS) symptoms of itchy eyes, watery eyes and eye redness; the symptom of postnasal drip will be rated, reflectively, twice daily (AM and PM) in a diary prior to the dose of study medication. Symptoms will be scored on a 0 to 3 scale (0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms, 3 = severe symptoms), such that the maximum daily symptom severity score will be 24 for the TNSS and 18 for the TOSS. Additional secondary efficacy variables will include reflective individual nasal and ocular symptom scores, as well as change from Baseline to Day 14 in the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ).

Subjects ≥ 18 years of age will complete the RQLQ on Day 1 (prior to dosing) and Day 14. Subjects will return to the clinic on Day 7 for an interim evaluation. After completing the 2-week double-blind treatment period, subjects will return to the clinic on Day 14 (or at time of early termination) for an end-of-study evaluation. Safety and tolerability assessments will be made on Days 7 and 14. Tolerability will be evaluated by subject-reported adverse events (AEs), nasal examinations, and vital signs assessments.
