Dataset from A Randomised, Double-blind, Parallel Group, Multicentre, Stratified, Study Evaluating the Efficacy and Safety of Once Daily Fluticasone Furoate/Vilanterol Inhalation Powder Compared to Once Daily Fluticasone Furoate Inhalation Powder in the Treatment of Asthma in Participants Aged 5 to 17 Years Old (Inclusive) Currently Uncontrolled on Inhaled Corticosteroids

The goal of asthma treatment is to achieve and maintain asthma control and to reduce the future risk of exacerbations. Inhaled corticosteroids (ICS) are considered as the most effective anti- inflammatory treatment for all severities of persistent asthma. For children \>=5 years of age and adolescents whose asthma is uncontrolled, low-dose ICS plus adjunctive therapy with long-acting beta agonist (LABA) is considered as effective. Thus, this study is designed to evaluate the efficacy and safety of FF (ICS component)/VI (LABA component) compared to FF alone for the treatment of asthma, in subjects aged 5 to 17 years old currently uncontrolled on ICS. The study will be conducted over a total duration of approximately 29 weeks: 4 week run-in period, 24-week double-blind treatment period and 1-week follow-up period. Subjects will be randomized to receive FDC of FF/VI or FF administered via ELLIPTA® dry powder inhaler (DPI). The dose of both FF/VI and FF alone will be selected based on the age of subjects. Subjects will receive a short acting beta 2 agonist (SABA) (albuterol /salbutamol) as a rescue medication throughout the study. A total of 870 subjects will be randomized in the study. Of this, 652 subjects will be aged 5 to 11 years (cohort A), and 218 will be aged 12 to 17 years inclusive (cohort B). ELLIPTA is a registered trademark of GlaxoSmithKline (GSK) group of companies.
