MeasureTime frameDescription
Change From Baseline in Total Nasal Symptom Score (TNSS) Assessed by the Investigator at Week 2Baseline and Week 2The investigator interviewed and examined participants to evaluate for nasal symptoms of: sneezing (daily frequency of attacks; score of 0=less than 1 time to 3=11+ times), rhinorrhea (daily frequency of blowing nose; score of 0=less than 1 time to 3=11+ times), nasal congestion (score of 0=less than nasal blockage without oral breathing to 3=severe nasal blockage causing prolonged oral breathing in a day), and nasal itching (score of 0=none to 3=nose is itchy, requiring frequent rubbing or blowing nose). The TNSS is the sum of the 4 nasal symptom sub-scores. TNSS scores could range from 0 to 12, with a higher score indicating more frequent/severe nasal symptoms.
Number of Participants Experiencing an Adverse Event (AE)Up to Week 4An AE is defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of the study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the study drug, is also an AE. The number of participants who experienced an AE, regardless of causality or severity, was summarized.
Number of Participants Discontinuing Study Drug Due to an AEUp to Week 2An AE is defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of the study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the study drug, is also an AE. The number of participants who discontinued study drug, whether permanently or temporarily, due to an AE was summarized.
