Outcomes

Primary Outcomes

Change From Baseline in Morning (AM) and Evening (PM) Total Asthma Symptom Severity (TASS)

Each morning prior to dosing and each evening approximately 12 hours later, the participant evaluated his/her asthma symptoms. The TASS was the sum of severity scores for 4 asthma symptoms: cough, wheeze, difficulty of breathing, and chest tightness. The severity of each asthma symptom was rated on a 4-point scale (0=no symptom; 3=severe); minimum TASS=0; maximum TASS=12. A decrease in TASS indicated an improvement in asthma symptoms. The Final Week was the final 7 days post Day 1 (e. g., if Day 20 was the day of last dose of study medication, then the AM assessment at Final Week was calculated from Day 14 to Day 20, and the PM assessment at Final Week was calculated from Day 13 to Day 19).

Time frame: Baseline up to Week 4

Secondary Outcomes

Change From Baseline in AM and PM Cough Symptom Score

Cough is an asthma symptom assessed by participants who used diary cards to record morning and evening cough (recorded twice daily). Every morning prior to dosing and each evening approximately 12 hours later, the participant evaluated his/her coughing for the time period since the last evaluation (or for the previous 12 hours for the first evaluation). Cough was rated on a 4-point scale (0=no symptoms \[best score\] to 3=symptoms were hard to tolerate and interfered with daily life activity \[worst score\]). Reduction in score indicated an improvement in cough symptoms. The Final Week was the final 7 days post Day 1 (e. g., if Day 20 was the day of last dose of study medication, then the AM assessment at Final Week was calculated from Day 14 to Day 20, and the PM assessment at Final Week was calculated from Day 13 to Day 19).

Time frame: Baseline up to Week 4

Change From Baseline in AM and PM Wheeze Symptom Score

Wheezing is a symptom of asthma. The wheezing assessment was based on participant diary data only. Every morning prior to dosing and each evening approximately 12 hours later, the participant evaluated his/her wheezing for the time period since the last evaluation (or for the previous 12 hours for the first evaluation). Wheeze severity was rated on a 4-point scale (0=no wheezing \[best score\] to 3=wheezing was hard to tolerate and interfered with daily life activity \[worst score\]). The Final Week was the final 7 days post Day 1 (e. g., if Day 20 was the day of last dose of study medication, then the AM assessment at Final Week was calculated from Day 14 to Day 20, and the PM assessment at Final Week was calculated from Day 13 to Day 19).

The severity of chest tightness was rated on a 4-point scale (0=no symptom \[best score\] to 3=symptoms were hard to tolerate and interfered with daily life activity \[worst score\]). The Final Week was the final 7 days post Day 1 (e. g., if Day 20 was the day of last dose of study medication, then the AM assessment at Final Week was calculated from Day 14 to Day 20, and the PM assessment at Final Week was calculated from Day 13 to Day 19).

Time frame: Baseline, Day 15 and Day 29

Change From Baseline in AM and PM Total Nasal Symptom Severity (TNSS)

The Total Nasal Symptom Severity (TNSS) is the sum of severity scores for 4 nasal symptoms: nasal rhinorrhea, nasal stuffiness/congestion, sneezing, and nasal itching as assessed in the participant diaries. The severity of each nasal symptom was rated on a 4-point scale (0=no symptom \[best score\] to 3=symptoms were hard to tolerate and interfered with daily life activity \[worst score\]); minimum TNSS=0; maximum TNSS=12. A decrease in TNSS indicated an improvement in nasal symptoms. The Final Week was the final 7 days post Day 1 (e. g., if Day 20 was the day of last dose of study medication, then the AM assessment at Final Week was calculated from Day 14 to Day 20, and the PM assessment at Final Week was calculated from Day 13 to Day 19).
