Abstract
AIMS: To investigate the magnitude of change in morning peak expiratory flow (PEF), asthma symptoms, and rescue beta2-agonist use, when the aim of treatment is to achieve guideline-defined control. METHODS: This was a protocol-defined analysis of data from the previously-reported one-year, stratified, randomised, double-blind, parallel-group GOAL study comparing the use of salmeterol/fluticasone propionate with fluticasone propionate alone in achieving guideline-defined control; this analysis assessed the magnitude of change in single specific endpoints which were amalgamated into the composite measure of control used in the primary GOAL analysis. RESULTS: Across all strata, improvements were seen for each outcome at 52 weeks as compared to baseline: mean morning PEF, 58.2 l/min (salmeterol/fluticasone propionate) versus 33.9 l/min (fluticasone propionate alone); symptom scores, -1.0 versus -0.8; symptom-free days, 72.5% versus 54.5%; mean of zero night awakenings, 31% versus 22%; rescue-free days, 87.3 versus 74.7; annualised rate of severe exacerbations, 0.02 versus 0.03; p<0.001 for all treatment differences. CONCLUSIONS: Aiming for guideline-defined control resulted in sustained, clinically relevant improvements in a range of individual asthma outcomes. Improvements were greatest with salmeterol/fluticasone propionate versus fluticasone propionate alone.
