Inclusion criteria

Key Inclusion Criteria: 1. Aged ≥12 years and older inclusive of either sex. 2. Documented clinical history of SAR (for at least 2 years preceding the Screening Visit \[Visit 1\]) with exacerbations (clinical evidence of active symptoms) during the study season for the mountain cedar pollen 3. A 12-hour reflective TNSS ≥ 8 out of a possible 12 and a congestion score of ≥ 2 for the AM assessment at the Screening Visit (Visit 1). Key

Exclusion criteria

1. Pregnant or lactating women. 2. Plans to travel outside the known pollen area for the investigative site for \> 24 hours during the last 7 days of run in period. 3. History of nasal polyps of other clinically significant respiratory tract malformations, recent nasal biopsy, nasal trauma (such as nasal piercing) or surgery, atopic dermatitis or rhinitis medicamentosa. 4. History of anaphylaxis and/or other severe local reaction(s) to skin testing. 5. History of positive test for HIV, Hepatitis B or Hepatitis C infection. 6. Documented evidence of acute or significant chronic sinusitis or chronic purulent postnasal drip. 7. Subjects with an active pulmonary disorder or infection. 8. Subjects with posterior subcapsular cataracts or glaucoma.

Design outcomes

Primary

MeasureTime frameDescription
Change in rTNSS From Baseline to End of Treatment14 daysSubjects were asked to assess rTNSS (reflective Total Nasal Symptom Score), ie, an evaluation of symptom severity over the past 12 hours prior to the recording of the score. The TNSS was defined as the sum of the subject-reported symptom severity scores for the following four nasal symptoms, recorded by each subject in the diary: rhinorrhea, sneezing, nasal congestion, nasal itching. The total rTNSS scores for all four symptoms (i.e, the lowest possible score (0) and the highest possible score (12).) Higher score means a worse outcome. The severity scale for each symptom evaluation was defined as follows: * 0 = absent (no sign/symptom evident) * 1 = mild (sign/symptom clearly present, but minimal awareness; easily tolerated) * 2 = moderate (definite awareness of sign/symptom that is bothersome but tolerable) * 3 = severe (sign/symptom that is hard to tolerate \[i.e., causes interference with activities of daily living and/or sleeping\])

Outcome results

Primary

Change in rTNSS From Baseline to End of Treatment

Subjects were asked to assess rTNSS (reflective Total Nasal Symptom Score), ie, an evaluation of symptom severity over the past 12 hours prior to the recording of the score. The TNSS was defined as the sum of the subject-reported symptom severity scores for the following four nasal symptoms, recorded by each subject in the diary: rhinorrhea, sneezing, nasal congestion, nasal itching. The total rTNSS scores for all four symptoms (i.e, the lowest possible score (0) and the highest possible score (12).) Higher score means a worse outcome. The severity scale for each symptom evaluation was defined as follows: * 0 = absent (no sign/symptom evident) * 1 = mild (sign/symptom clearly present, but minimal awareness; easily tolerated) * 2 = moderate (definite awareness of sign/symptom that is bothersome but tolerable) * 3 = severe (sign/symptom that is hard to tolerate \[i.e., causes interference with activities of daily living and/or sleeping\])

Time frame: 14 days

Population: The full analysis set (FAS) included all randomized subjects who received at least one dose of randomized study medication and had at least one post-baseline primary efficacy assessment. This was the primary analysis set for efficacy analyses.
