Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryMean Change From Baseline in Daytime Nasal Symptoms Score Over 2 WeeksBaseline and Week 2
Mean change from baseline in Daytime Nasal Symptoms score. Patients were asked to rate each of the 4 nasal symptoms of Congestion, Rhinorrhea, Itching, and Sneezing daily on a 4-point scale. The average of the 4 individual nasal symptoms scores was reported as the Daytime Nasal Symptoms Score. Scores were measured as 0 (best) to 3 (worst).
SecondaryMean Change From Baseline in Nighttime Symptoms Score Over 2 WeeksBaseline and Week 2
Mean change from baseline in Nighttime Symptoms Score. Patients were asked to rate each symptom daily on a 4-point scale, and the combined score of Nasal Congestion Upon Awakening, Difficulty Going to Sleep, and Nighttime Awakenings was reported as the Nighttime Symptoms Score. Scores were measured as 0 (best) to 3 (worst).
SecondaryMean Change From Baseline in Daytime Eye Symptoms Score Over 2 WeeksBaseline and Week 2
Mean change from baseline in Daytime Eye Symptoms scores. Patients were asked to rate each of the 4 eye symptoms of tearing, itchy, red, and puffy eyes daily on a 4-point scale. The average of the 4 individual eye symptoms scores was reported as the Daytime Eye Symptoms Score. Scores were measured as 0 (best) to 3 (worst).
SecondaryPatient's Global Evaluation of Allergic Rhinitis at Week 2Week 2
An evaluation by the patient, administered at the last visit (or upon discontinuation) using a 7-point scale, of the change in symptoms as compared to the beginning of the study. Scores were measured as 0 (best) to 6 (worst).
SecondaryPhysician's Global Evaluation of Allergic Rhinitis at Week 2Week 2
An evaluation by the physician, administered at the last visit (or upon discontinuation) using a 7-point scale, of the change in symptoms as compared to the beginning of the study. Scores were measured as 0 (best) to 6 (worst).
SecondaryMean Change From Baseline in Rhinoconjunctivitis Quality-of-life Questionnaire (RQLQ) Overall Score at Week 2Week 2
Patients completed the validated, self-administered RQLQ, which included 28 items on a 7-point scale across 7 domains: activities, sleep, non-nose/eye symptoms, practical problems, nasal symptoms, eye symptoms, and emotional. Scores for each domain were averaged, then scores for the 7 domains were averaged for the overall score. Scores were measured as 0 (best) to 6 (worst).
