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.

Eligibility Criteria

Inclusion Criteria

• Informed consent: Written informed consent from at least one parent/care giver and the accompanying informed assent from the subject (where the subject is able to provide assent) prior to admission to the study.

If applicable, subject must be able and willing to give assent to take part in the study according to the local requirement. The study investigator is accountable for determining a child's capacity to assent to participation in a research study, taking into consideration any standards set by the responsible Independent Ethics Committee (IEC)/Institutional Review Board (IRB).

Subject and their legal guardian understands that they must comply with study medication and study assessments.

• Age: 5-11 years (inclusive) at Visit 1.
• Weight: Subjects must weigh at least 17 kilograms (kg).
• Gender: Male and pre-menarchial female. Pre-menarchial females are defined as any female who has yet to begin menses.
• Diagnosis of asthma: Subjects must have a diagnosis of asthma documented in their medical history at least 6 months prior to Visit 1.
• Childhood Asthma Control Test (C-ACT): Subjects must have a C-ACT score of >19.

• Ability to use Dry Powder Inhalers: Subjects must demonstrate the ability to use the ELLIPTA inhaler under the supervision of their parents/caregiver.
• SABA: All subjects must be able to replace their current SABA treatment with albuterol/salbutamol aerosol inhaler at Visit 1 for use as needed for the duration of the study. Albuterol/salbutamol metered dose inhaler (MDI) will be administered with or without a spacer, to be used as determined by the investigator. The use or non-use of the spacer should be consistent for an individual subject throughout the study.
• Peak Flow Meter/Daily Diary Compliance: A subject must be able to use the study-provided peak flow meter and the subject/caregiver must be able to maintain the electronic diary record.

Exclusion Criteria
