Last updated: February 3, 2009
Last verified: February 2009
Explorative comparison of montelukast with inhaled steroids (fluticasone) to estimate responder profiles, in terms of symptom scores, rescue medication, increase of FEV1, in correlation to presence of allergy, bronchial hyperreactivity (PD20), exhaled NO, excretion of leukotrienes, response to RABA and laboratory parameters in patients with pre-school asthma i.e. asthma phenotypes.

Condition Intervention Phase

Study Type: Interventional
Study Design: Allocation: Randomized

Further study details as provided by Johann Wolfgang Goethe University Hospital:

Primary Outcome Measures:
  • The primary efficacy variable is the number of responders with a very good asthma symptom control defined as requiring no rapid acting beta agonist (RABA) between the 2. and 6th week of intervention (end of trial)

Secondary Outcome Measures:
  • the number of patients requiring at least five times RABA between the 2. and 6th week, the number of patients with an increase of FEV1 7.5%, the symptom score, symptom free days, rescue medication, presence of allergy RAST > 2, concentration of eNO, PD20

Estimated Enrollment: 100
