Brief Summary

The aim of this study is to compare two licensed asthma inhalers and to then evaluate the safety of reducing treatment when patient's asthma is in control. The inhalers used in this study are the Seretide® 250 Evohaler®, which is widely used in UK, and a recently licensed inhaler called Flutiform®. National guidelines recommend that asthma medication should be increased when patients are experiencing worsening of their asthma, and reduced when asthma is in control. However, it is likely that in daily clinical practice some patients are over-treated. It is therefore necessary to conduct more studies which demonstrate that reducing treatment dosage can be done safely. This study has two phases. In the first phase the investigators aim to recruit 224 patients through approximately 40 clinics in the UK and Ireland. One third of these patients will be selected in random to use the high dosage Seretide® 250 Evohaler® and two thirds will use high dose Flutiform® 250 inhaler for 12 weeks. At the end of phase 1 the investigators will compare how well asthma was controlled between the two groups. After phase 1 those patients who used Flutiform and did not have any problems with their asthma can participate in phase 2. In phase 2 half of the patients will stay on high dosage Flutiform 250 and half will be switched to the medium dosage Flutiform 125 inhaler. At the end of phase 2 the investigators will compare asthma control between the two groups. This study will be conducted by Research in Real Life Ltd (Cambridge, UK) with partial funding from Napp Pharmaceuticals Ltd. The estimated total duration of the study is 18 months and each patient will spend a maximum of 6 months in the study.

Study Arms (3)

Seretide 250

ACTIVE COMPARATOR

Seretide® Evohaler® 25 microgram /50 microgram per metered dose pressurised inhalation, suspension. 25 micrograms of salmeterol (as salmeterol xinafoate) and 250 micrograms of fluticasone propionate. This is equivalent to a delivered dose (ex actuator) of 21 micrograms of salmeterol and 220 micrograms of fluticasone propionate. 2 puffs twice daily for 12 weeks Phase 1.

Drug: Fluticasone 250/salmeterol 25

Flutiform 250

ACTIVE COMPARATOR

flutiform® 250 microgram/10 microgram per actuation pressurised inhalation, suspensions. 250 micrograms of fluticasone propionate and 10 micrograms of formoterol fumarate dihydrate. This is equivalent to a delivered dose (ex-actuator) of approximately 230 microgram of fluticasone propionate/9.0 microgram of formoterol fumarate dihydrate. 2 puffs twice daily for 12 weeks in Phase 1 and 12 weeks in Phase 2.

Drug: Fluticasone 250/formoterol 10

Flutiform 125

ACTIVE COMPARATOR

flutiform 125 microgram/5 microgram per actuation pressurised inhalation, suspensions. 125 micrograms of fluticasone propionate and 5 micrograms of formoterol fumarate dihydrate. This is equivalent to a delivered dose (ex-actuator) of approximately 115 microgram of fluticasone propionate/4.5 microgram of formoterol fumarate dihydrate. 2 puffs twice daily for 12 weeks in Phase 2.

Drug: Fluticasone 125/formoterol 5
