Efficacy and Safety of Fluticasone Propionate(FP)/ Salmeterol Xinafoate (SLM) Hydro Fluoro Alkane (HFA) Metered Dose Inhaler (MDI) in Pediatric Patients With Bronchial Asthma

The participant's parent or legally acceptable representative recorded asthma symptoms experienced by the participant during the night in a patient diary in the form of scores on a 4-point rating scale from Baseline (Week -1) until end of TP1 (Week 8). Scores ranged from 0 to 3(0: one, 1: mild, 2: moderate, 3: severe) and maximum score is 3 per day. Change from Baseline in the asthma symptom scores at night time at the end of TP1 was analyzed. 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 and completed their diary were analyzed.

The definition of exacerbations was amended during the study. <Original> An exacerbation is defined as deterioration of asthma requiring the use of systemic corticosteroids (oral, parenteral, or depot) for at least 3 days or an in-patient hospitalization or emergency department visit due to asthma that required systemic corticosteroids. <Amendment> An asthma exacerbation is defined as deterioration of asthma requiring the use of prednisone or hydrocortisone equivalent systemic corticosteroids for at least 3 days, or requiring the use of dexamethasone or betametasone equivalent systemic corticosteroids (oral, intravenous or intramuscular), or requiring the use of systemic depot corticosteroids once, or an in-patient hospitalization that required treatment for respiratory symptom with wheezing, or emergency department visit due to asthma that required intravenous systemic corticosteroids.

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.

The number of inhalations of rescue salbutamol inhalation aerosol (medication used to relieve symptoms immediately) used during the day and night was recorded by the participant's parent or legally acceptable representative twice daily in a patient diary from Baseline (Week -1) until Week 8. 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. Participants who completed TP1 and completed their diary were analyzed.

The participant's parent or legally acceptable representative recorded asthma symptoms experienced by the participant in a patient diary twice daily (daytime and night time) in the form of scores on a 4-point rating scale from Baseline (Week -1) until end of TP2 (Week 24). Scores ranged from 0 (none) to 3 (severe) and maximum score is 6 per day. Change from Baseline in the asthma symptom scores at daytime plus night time at the end of TP2 was analyzed. 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 TP2 value is a mean value of the last 7 consecutive days during the TP2 (excluding the last day of the TP2). Change from Baseline is the difference between the value of the endpoint at the time point of interest and the Baseline value. Participants who received at least one dose of open-label medication in the TP2 were analyzed.
