Recruitment details |
This study evaluated the efficacy and safety of (FP)/salmeterol xinafoate (SLM) HFA twice-daily (BID) via metered-dose inhaler (MDI) for 8 weeks in comparison with FP HFA MDI in 6-months to 4-years-old Japanese participants (par.) with infantile bronchial asthma. The results presented are based on the Interim Analysis. | ||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||
Screening details |
Eligible par. at screening entered a 2-week run-in period to receive FP HFA MDI 50 µg, followed by 8-week double-blind treatment period (TP) 1 to receive FP/SLM HFA MDI 50/25 µg or FP HFA MDI 50 µg. In TP2, par. received FP/SLM HFA MDI 50/25 µg for 16 weeks (open-label phase). The total duration of the study was 27 weeks with follow-up. | ||||||||||||||||||||||||

End point description |
The participant’s parent or legally acceptable representative made entries asthma symptom experienced by the participant in a patient diary twice daily (day time and night time) in the form of scores on a 4-point rating scale from Baseline (Week -1) until end of TP1 (Week 8). The Baseline value is a mean value of the last 7 consecutive days during the run-in period (excluding the day of Visit 2 [Randomization]).The end of the TP1 value is a mean value of the last 7 consecutive days during the TP1 (excluding the last day of the TP1). Change from Baseline is the difference between the value of the endpoint at the time point of interest and the Baseline value. Participants who completed TP1 were analyzed.

Severity and control statuses based on Japanese pediatric guideline for the treatment and management of asthma (JPGL) can be assessed according to JPAC. Theoretically range of JPAC score was 0 (poor control) to 18 (complete control) point. JPAC questionnaire was recorded at Baseline (Week -2) and Week 8 by the participant's parent or legally acceptable representative who knew the participant's asthma for the last month. Change from Baseline is the difference between the value of the endpoint at the time point of interest and the Baseline value. Participants who completed TP1 were analyzed.

A 24-hour period in which a participant's responses to both the morning and evening assessments indicated no use of rescue medication was considered as rescue free. Participants who were rescue free for 24-hour periods during the 8 weeks in TP1 were assessed. The Baseline value was derived from the last 7 days of the patient diary prior to the randomization of the participant. Change from Baseline is the difference between the value of the endpoint at the time point of interest and the Baseline value.

A 24-hour period in which a participant's responses to both the morning and evening assessments indicated no use of rescue medication was considered as rescue free. Participants who were rescue free for 24-hour periods during the 4-week Treatment Period were assessed. The Baseline value was derived from the last 7 days of the patient diary prior to the randomization of the participant. Change from Baseline is calculated as the average value during the 8 weeks in TP1 minus the value at Baseline. Participants who completed TP1 were analyzed.
