Brief Summary

Inhaled corticosteroids (ICS) have a number of known class effects including hypothalamic-pituitary-adrenocortical (HPA) axis suppression. Although the safety of inhaled Fluticasone Furoate (FF) on the HPA axis of adults and adolescent asthmatic patients has been established, it is important to assess the risk of suppression in children so as to establish whether this medicine can be safely used in this young population. This study aims to evaluate the effect of inhaled FF on the HPA axis of children 5-11 years of age (inclusive) with persistent asthma compared with placebo. Approximately 143 subjects will be enrolled. Subjects will enter a 7 to 14 day run-in period on oral montelukast 4 milligrams (mg) (5 year old subjects) or 5 mg (6-11 year old subjects) once daily. Eligible subjects will be randomized to receive once-daily FF inhalation powder 50 micrograms (mcg) or once-daily placebo inhalation powder in the morning via the ELLIPTA™ inhaler for 42 days. Subjects will continue to receive open label montelukast during the treatment period. All subjects will be provided albuterol/salbutamol inhalation aerosol, to use as needed to treat acute asthma symptoms throughout the study.

Outcome Measures

Primary Outcomes (2)

• Change From Baseline (Expressed as a Ratio) in 0-24 Hour Weighted Mean Serum Cortisol at the End of the Six Week Treatment Period (D 42) in Intention-to-treat (ITT) Population

  The blood samples for statistical analysis of serum cortisol (SC) endpoints were collected on D 0 and D 42 at the indicated time points. The weighted mean was calculated by dividing the area under the curve (AUC) over the 24-hour (hr) time period by the time period. Change from Baseline in 0-24 hr weighted mean SC was calculated as a ratio from Baseline defined as the SC weighted mean (0-24 hours) at Week 6 divided by the Baseline SC weighted mean (0-24 hours).The ratio from Baseline was loge transformed prior to analysis. The loge transformed ratios were compared between treatment groups as treatment ratios, using an analysis of covariance (ANCOVA) model, allowing for the effects of Baseline (loge transformed), age, sex and region. Treatment ratios for comparison was calculated by back-transforming the difference between the Least square (LS) means. Using the pooled estimate of variance, 95% Confidence Intervals (CIs) was calculated for the difference.

  Baseline, D 0 (Pre-dose, 2hr, 4hr, 8hr, 12hr, 16hr and 24hr) and Day 42 (0hr, 2hr, 4hr, 8hr, 16hr and 24hr)

• Change From Baseline (Expressed as a Ratio) in 0-24 Hour Weighted Mean Serum Cortisol at the End of the Six Week Treatment Period (Day 42) in SC Population

  The blood samples for statistical analysis of serum cortisol (SC) endpoints were collected on D0 and D42 at indicated time points. The weighted mean was calculated by dividing the area under curve (AUC) over the 24-hr time period by time period. Change from Baseline in 0-24 hr weighted mean SC was calculated as a ratio from baseline defined as SC weighted mean (0-24 hrs) at Wk 6 divided by the baseline SC weighted mean (0-24 hrs). The ratio as treatment ratios, using an analysis of covariance (ANCOVA) model, allowing for the effects of baseline (loge transformed from baseline was loge transformed prior to analysis. The loge transformed ratios were compared between treatment groups), age, sex and region. Treatment ratios for comparison was calculated by back-transforming the difference between Least square (LS) means. Using the pooled estimate of variance, 95% CIs) was calculated for the difference.
