Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Placebo nasal spray
Mometasone	Mometasone	Mometasone furoate nasal spray (50 mcg per actuation)
Azelastine	Azelastine	Azelastine hydrochloride nasal spray (140 mcg per actuation)
Mometasone + Azelastine	Mometasone	Mometasone + Azelastine (50 + 140 mcg per actuation)
Mometasone + Azelastine	Azelastine	Mometasone + Azelastine (50 + 140 mcg per actuation)

Primary Outcome Measures

Name	Time	Method
Change from baseline in the daily Total Nasal Symptom Score (TNSS)	Baseline, Day 7	The benefit of the treatment with the fixed combination medicinal product Momeatsone+Azelastine nasal spray (test product) in comparison to the treatment with the individual medicinal products Mometasone nasal spray and Azelastine nasal spray (comparator products) will be assessed by comparing the change from baseline in the daily Total Nasal Symptom Score (TNSS) during the first seven days of treatment. Total Nasal Symptom Score (TNSS) of 4 symptoms (rhinorrhea, sneezing, nasal itching, and nasal congestion) will be assessed by the patient in a patient's diary. Each symptom will be scored on a 4-point scale where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms, and 3 = severe symptoms, such that the maximum TNSS is 12.

Secondary Outcome Measures

Name	Time	Method
Baseline-adjusted differences in nasal obstruction assessed by peak nasal inspiratory flow measurements (PNIF)	Baseline, Day 7 and Day 14	The PNIF will be performed by means of portable In-Check Nasal flow meter using a face mask which the patient applies over the nose (without touching it) with the mouth closed. The In-Check Nasal is a portable inspiratory flow meter, measuring inspiratory flow between 30-370 L/min.
Number of responders with an improvement of ≥ 0.5 points in the assessment of overall RQLQ	Baseline, Day 7 and Day 14	Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) has 28 questions in 7 domains (activity limitation, sleep problems, nose symptoms, eye symptoms, non-nose/eye symptoms, practical problems and emotional function). There are 3 'patient-specific' questions in the activity domain which allow patients to select 3 activities in which they are most limited by their rhinoconjunctivitis. Patients recall how bothered they have been by their rhinoconjunctivitis during the previous week and to respond to each question on a 7-point scale (0 = not impaired at all - 6 = severely impaired). The overall RQLQ score is the mean of all 28 responses and the individual domain scores are the means of the items in those domains.
Change from baseline in individual daily ocular symptoms	Baseline, Day 7 and Day 14	Ocular itching and Redness and Ocular tearing will be scored on a 4-point scale where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms, and 3 = severe symptoms. The symptoms will be assessed by the patient in a patient's diary starting at Visit 1. The patient will document the ocular symptoms in the evening retrospectively for each day of treatment until treatment day 14.
Change from baseline in Rhinoscopy score	Baseline, Day 7 and Day 14	Rhinoscopy score: during the nasal examination the investigator will evaluate the symptoms rhinorrhea, redness and edema using a 4-point scale as follows: absent = 0, mild = 1, moderate = 2, and severe = 3.
Change from baseline in the daily Total Nasal Symptom Score (TNSS)	Baseline, Day 14	Total Nasal Symptom Score (TNSS) of 4 symptoms (rhinorrhea, sneezing, nasal itching, and nasal congestion) will be assessed by the patient in a patient's diary starting at Visit 1 for the baseline run-in period (3 to 5 days). The mean of the symptom scores during the last 3 days prior to Visit 2 will be used to calculate baseline symptoms. Following randomization at Visit 2, the patient will document the TNSS in the evening retrospectively for each day of treatment until treatment day 14. Each symptom will be scored on a 4-point scale where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms, and 3 = severe symptoms, such that the maximum TNSS is 12.
Intra-group changes in health-related Quality of Life (RQLQ)	Baseline, Day 7 and Day 14	Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) has 28 questions in 7 domains (activity limitation, sleep problems, nose symptoms, eye symptoms, non-nose/eye symptoms, practical problems and emotional function). There are 3 'patient-specific' questions in the activity domain which allow patients to select 3 activities in which they are most limited by their rhinoconjunctivitis. Patients recall how bothered they have been by their rhinoconjunctivitis during the previous week and to respond to each question on a 7-point scale (0 = not impaired at all - 6 = severely impaired). The overall RQLQ score is the mean of all 28 responses and the individual domain scores are the means of the items in those domains.
Change from baseline in individual daily nasal symptoms	Baseline, Day 7 and Day 14	Change from baseline in individual daily nasal symptoms (nasal congestion, rhinorrhea, nasal itching and sneezing) during 7 and 14 days of treatment for all four arms will be assessed.
Intra-group changes in the Rhinitis Control Assessment Test (RCAT) score	Baseline, Day 7 and Day 14	Rhinitis Control Assessment Test (RCAT) questionnaire has 6 items that include nasal congestion, sneezing, watery eyes, sleep problems caused by rhinitis, activity avoidance, and nasal or other allergy symptoms control. Responses are measured on a 5-point scales. RCAT scores range from 6 to 30, with higher scores indicating better rhinitis control.
Number of responders with a RCAT score ≥22	Baseline, Day 7 and Day 14	Rhinitis Control Assessment Test (RCAT) questionnaire has 6 items that include nasal congestion, sneezing, watery eyes, sleep problems caused by rhinitis, activity avoidance, and nasal or other allergy symptoms control. Responses are measured on a 5-point scales. RCAT scores range from 6 to 30, with higher scores indicating better rhinitis control.
Onset of action: Instantaneous TNSS	On Day 2 (first day of treatment) from 0 to 8 hours (at 5 minutes, 15 minutes, 30 minutes, 1 h, 2 h, 4 h, 8 h) after the first dose administration	Instantaneous Total Nasal Symptom Score (TNSS) of 4 symptoms (rhinorrhea, sneezing, nasal itching, and nasal congestion) will be assessed by the patient in a patient's diary.
Onset of action: instantaneous ocular symptoms	On Day 2 (first day of treatment) from 0 to 8 hours (at 5 minutes, 15 minutes, 30 minutes, 1 h, 2 h, 4 h, 8 h) after the first dose administration	Instantaneous Ocular itching and Redness and Ocular tearing will be scored on a 4-point scale where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms, and 3 = severe symptoms.
