Reflective TNSS is an evaluation of symptom severity over the past 12 hours prior to the recording of the score. Participants (with assistance from parents/guardians/caregivers, as needed) assessed and recorded four nasal symptoms (runny nose, nasal congestion, nasal itching, and sneezing) twice daily (AM and PM) using the following scale: * 0 = absent (no sign/symptom present) * 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; causes interference with activities of daily living and/or sleeping) The total TNSS scale was 0-12 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. Baseline and the during study rTNSS values were defined as the average AM and PM subject-reported rTNSS during each time period.

The serum cortisol weighted mean (0-t), calculated by dividing the area under the concentration-time curve (AUC) from time zero to the time of the last measurable value over the 24-hour period by the sample collection time interval, was determined for each participant at baseline and Week 6, and the ratio of Week 6 over baseline was derived.
