Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Specific airway resistance (sRAW kPa.L.s) measured before the study medication dose at the end of treatment (week 4)

Secondary Outcome Measures:
  • sRAW measured post-dose at Week 2 and week 4. % symptom-free days over Weeks 1-4. % symptom-free nights over Weeks 1-4. Type and frequency of adverse events.

Enrollment: 48
Study Start Date: December 2002
Detailed Description:
Single centre, randomised, double-blind, comparator study to demonstrate superiority of salmeterol/fluticasone propionate combination product 50/100mcg bd over fluticasone propionate 100mcg bd with respect to improvements in airway physiology (sRAW) in adults with persistent asthma treated for 4 weeks.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No


  • Physician documented diagnosis of asthma which has been present for at least 6 months.
  • Receiving a total daily dose of 200-500mcg/day beclomethasone dipropionate or equivalent for at least 4 weeks prior to the start of the run-in period.


  • Has had 3 or more courses of oral corticosteroids in the 12 months previous to visit 1
