Clinical Equivalence Study of Mometasone Nasal Spray

Inclusion Criteria

• Male or non-pregnant non-lactating female
• 12 years of age or older
• Signed informed consent form, which meets all criteria of current FDA regulations. For patients under the age of majority in the state the study is being conducted (18 years in most states) the parent or legal guardian should sign the consent form and the child will be required to sign a patient "assent" form that will be written in such a way as to be understandable to a child.
• If female and of child-bearing potential, have a negative urine pregnancy test and is prepared to abstain from sexual intercourse or use a reliable method of contraception during the study (e.g., condom with spermicide, IUD, oral, injected, transdermal or implanted hormonal contraceptives). In order for hormonal birth control to be considered a reliable method the patient must have been on their regimen for at least 28 days.
• Documented positive allergic skin test, performed within the previous 12 months, to one or more of the allergens in season at the time the study is being conducted.
• A minimum of two consecutive years of previous history of seasonal allergic rhinitis to the pollen/allergen in season at the time the study is being conducted.
• A score of at least 6 on the reflective Total Nasal Symptom Score (rTNSS) and a minimum score of at least 2 for "nasal congestion" and a minimum score of at least 2 for one of the remaining 3 symptoms (see Appendix A) representing the 12 hours prior to the screening visit.
• An average composite score of at least 6 on the reflective Total Nasal Symptom Score (rTNSS) and a minimum score of at least 2 for "nasal congestion" and a minimum score of at least 2 for one of the remaining 3 symptoms (see Appendix A) representing the last 3 days of the 7-day placebo run-in period before the randomization visit and the morning of the first day of the randomization visit.

Exclusion Criteria

• Under 12 years of age.
• Females who are pregnant, lactating or likely to become pregnant during the study.
• Negative or lack of documented skin allergen test (performed within the previous 12 months) to at least one of the allergens in season at the time the study is being conducted. The results of all positive skin allergen test results should be reported.
• Patients who suffer from chronic signs and symptoms of Perennial Allergic Rhinitis (PAR) should be excluded from the study unless the Investigator assesses that the patient's current signs and symptoms are a clear exacerbation of Seasonal Allergic Rhinitis (SAR) rather than chronic PAR.
• Patients who suffer only from perennial allergic rhinitis or seasonal allergic rhinitis to a different allergen than that in season at the time the study is conducted.
• Previous history of less than 2 years of seasonal allergic rhinitis to the pollen/allergen in season at the time the study is being conducted.
• A total score of less than 6 on the reflective Total Nasal Symptom Score (rTNSS) or a score less than 2 for "nasal congestion" or a score less than 2 for all 3 of the remaining symptoms (see Appendix A). Any patient who meets the minimum rTNSS requirements at the start of the placebo lead-in period but no longer meets the requirements prior to the randomized active treatment period of the study cannot continue in the active treatment period.
• History of asthma over the previous two years that required chronic therapy. Occasional acute or mild exercise induced asthma will be allowable on the condition that the treatment of the attacks is restricted to beta-agonists only.
• Patients with nasal conditions, including infectious rhinitis, rhinitis medicamentosa or atrophic rhinitis.
• Clinically significant nasal deformity (e.g. significantly deformed septum, nasal polyps or ulcers) or any recent nasal surgery or trauma that has not completely healed.
• Sinus infection within the previous 30 days or history of re-occurring sinus infections.
• Patient has started immunotherapy (including
