  • Subject must be willing to maintain same environment throughout the study.
  • Subject and/or subject's parent/guardian understands and is willing, able and likely to comply with study procedures and restrictions as well as manage study drug administration.

Exclusion criteria

  • Concomitant Medical Conditions: (a) Significant concomitant medical conditions defined as historical or current evidence of clinically significant uncontrolled disease of any body system. Significant is defined as any disease that, in the opinion of the investigator, would confound the interpretation of the study results if the disease/condition exacerbated during the study: significant renal impairment, which based on the opinion of the investigator, would preclude the subjects' participation in the study and current active liver or biliary disease (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment). (NOTES: Stable chronic liver disease should generally be defined by the absence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or gastric varices, or persistent jaundice, or cirrhosis and Chronic stable hepatitis B and C [e.g., presence of hepatitis B surface antigen (HBsAg) or positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment] are acceptable if subject otherwise meets entry criteria). (b) A severe physical obstruction of the nose (e.g., deviated septum or nasal polyp) or frequent bleeding of the nose that could affect the deposition of double blind intranasal study drug. (c) Current or history of a Candida infection of the nose or oropharynx, shingles, chickenpox, measles, ocular herpes simplex. (d) Known hypersensitivity to corticosteroids or any excipients in the product. (e) Recent nasal septal surgery or nasal septal perforation. (f) Subjects start, discontinue or change desensitization treatment within 30 days prior to Visit 1. (g) Bacterial or viral infection of the eyes or upper respiratory tract within two weeks of Visit 1 or during the screening period. (h) Asthma, with the exception of mild intermittent asthma. (i) Diagnosis of rhinitis medicamentosa, vasomotor AR or eosinophil rhinitis.

  • Abnormal Electocardiogram (ECG): Clinically significant abnormal ECG finding at Visit 1. Significant is defined as: Corrected QT (QTc) > 450 milliseconds (msec) or QTc > 480 msec in subjects with Bundle Branch Block. The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB), Fridericia's formula (QTcF), and/or another method, machine-read or manually over-read. The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trail.
  • Concomitant Medication: Use of prescription or over-the-counter medication that would significantly affect the course of AR, or interact with study drug, such as: Chronic use of concomitant medications such as tricyclic antidepressants, that would affect assessment of the effectiveness of the study drug; Chronic use of long- acting beta2-agonists (e.g., salmeterol); Potent Cytochrome P450 subfamily enzyme 3A4 [CYP3A4] inhibitors (e.g., ritonavir, ketoconazole, itraconazole, clarithromycin, etc); Allergen immunotherapy for the treatment of allergies.

Primary outcomes

  1. Mean Change From Baseline in Daily, Reflective Total Nasal Symptom Scores (rTNSS) Over the First 2 Weeks Treatment Period

    Time frame: Baseline and up to Week 2

    TNSS is a composite score of the four components (nasal congestion, itching, rhinorrhea and sneezing) with a total score of 0 to 12. A higher score means a worse nasal symptom. The score of each component ranges from 0 (no symptom) to 3 (severe symptoms). Participants were instructed to provide scores in a reflective manner using their diary. The daily rTNSS was the average of the morning rTNSS and evening rTNSS assessments. The daily scores were averaged to calculate the overall/total score. The morning reflective assessment was performed prior to administering the morning dose. The evening reflective assessment was performed approximately 12 hours after dosing but before bedtime. Baseline scores obtained over "4 days prior to randomization" were average of the last 8 rTNSS assessments (4 AM assessments, 4 PM assessments) over the consecutive four 24-hours periods prior to randomization. Change from Baseline was defined as post-dose visit value minus Baseline value.
