Clinical Trial Outcome Measures

Primary Measures

  • Change in rTNSS From Baseline to End of Treatment
    • Time Frame: 14 days
    • 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).) 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])
