Seretide evidence

Seretide efficacy and clinical evidence

Read the information below to understand the key clinical evidence for Seretide in asthma and COPD.

Asthma summary

Asthma patients uncontrolled on ≤ 500mcgs BDP or equivalent when stepped up to Seretide can
experience
[1],[2]

  • 88% of rescue medication free days over one year*
  • 74% of symptom free days over one year*
  • 75% patients achieved guideline-defined control after one year

* This was demonstrated in a post-hoc analysis of the GOAL study.[1],[2]

COPD summary

Short-term benefits

COPD patients on Seretide 500 Diskus experienced an improvement in:

  • lung function after 24 hours measured as PEFR vs. placebo, salmeterol and fluticasone propionate in a patient subgroup with baseline FEV1 <50% predicted (p<0.0001)[3]
  • breathlessness after 48 hours compared with placebo in a patient subgroup with baseline FEV1 <50% predicted (p<0.001)[3]

Long-term benefits

TORCH was a 3 year study. The primary endpoint of the effect of Seretide 500 Diskus on all-cause mortality did not meet statistical significance; P=0.052 [4]

Additionally, over 3 years, COPD patients taking Seretide 500 Diskus experienced:

  • a 43% reduction in the rate of exacerbations requiring oral steroids compared with placebo (p<0.001) ARR = – 0.34 exacerbations/yr (0.46 Seretide 500 Diskus vs. 0.80 placebo) [4]
  • Improvement in quality of life measured with SGRQ [4]
  • Reduced rate of lung function decline by 16mL per year compared with placebo (in a post-hoc analysis) (p<0.001) [5]
