Clinical Study Evaluating Safety and Efficacy of Fluticasone Furoate and Fluticasone Propionate in People With Asthma

This will be a multi-centre, randomised, placebo and active controlled (with rescue
medication), double-blind, double-dummy, parallel-group study. Subjects meeting all the
inclusion criteria and none of the exclusion criteria during Visit 1 (Screening Visit) will
enter a two week Run-in Period. Subjects failing screening will not be eligible for
re-screening. During the run-in and double-blind treatment periods subjects will maintain an
electronic daily diary to record morning and evening peak expiratory flow (PEF), asthma
symptom scores and rescue albuterol/salbutamol use. At Visit 2 (end of run-in/Randomisation
Visit), subjects meeting the eligibility criteria will be randomised receive treatment with
either fluticasone furoate 50 mcg once daily, fluticasone propionate 100 mcg twice daily or
placebo. In addition all subjects will be supplied with albuterol/salbutamol inhalation
aerosol to use as required to treat symptoms. Subjects will attend 6 on-treatment visits at
Visits 3, 4, 5, 6, 7 and 8 (Weeks 2, 4, 8, 12, 18 and 24 respectively). Subjects will
receive treatment for 24 weeks. A follow-up contact will be performed 1-week after
completing study medication (Visit 9). Subjects will participate in the study for up to a
maximum of 27 weeks (including screening, treatment and follow-up contact).
