Exercise Induced Bronchospasm in Children

Overview[ - collapse ][ - ]

Purpose The purpose of the study is to test how well 2 different medications stop asthma symptoms caused by exercising. The two medications that will be tested are "pretreatment with albuterol" and montelukast (Singulair®). Although both medications are used for treating asthma, we don't know which medicine is better at stopping asthma symptoms caused by exercising.

Current Primary Outcome MeasuresThe primary outcome will be the comparison of the effect of inhaled albuterol and oral montelukast on EIB as percent attenuation in FEV1 after exercise challenge. [Time Frame: Fall in FEV1 immediately after exercise] [Designated as safety issue: Yes]
Current Secondary Outcome MeasuresAdditional objectives will be to compare the differences in response to montelukast with regard to LTB4 concentrations from EBC and FeNO level [Time Frame: immediately after exercise] [Designated as safety issue: Yes]

Official Title"Pretreatment With Albuterol vs. Montelukast in Exercise Induced Bronchospasm in Children."
Brief Summary
The purpose of the study is to test how well 2 different medications stop asthma symptoms
caused by exercising. The two medications that will be tested are "pretreatment with
albuterol" and montelukast (Singulair®). Although both medications are used for
treating asthma, we don't know which medicine is better at stopping asthma symptoms caused
by exercising.
Detailed Description
TThis is a randomized, crossover, placebo controlled trial of 30 patients, 7-17 years old
with confirmed EIB. Patients will be randomized to montelukast treatment for at least 3 days
or pretreatment with albuterol before an exercise challenge. Villiran and colleagues have
shown that the protective effect of montelukast in treating EIB is apparent at day 3 of
treatment and comparable to treatment for 4 and 8 weeks.

It is our hypothesis that pretreatment with albuterol will provide superior protection
against breakthrough EIB in children with mild asthma compared to montelukast as maintenance
therapy added to the current asthma regimen. Secondary aims of this study are to measure
the effect of montelukast on leukotriene B4 (LTB4) concentrations as measured in EBC, and on
inflammation measured by FeNO level. We hypothesize that since montelukast is a cysteinyl
leukotriene receptor antagonist, patients with elevated concentration of LTB4 may have a
greater response to this medication. Lastly, patients with elevated FeNO, a measure of
airway inflammation respond differently to albuterol than montelukast his study is a
randomized, double-blind, double-dummy, crossover clinical trial which will consist of 4
study visits and last up to 3 weeks.

Thirty children 7-17 years of age with asthma and EIB, regardless of current asthma therapy
will be eligible for this trial. Patients will receive 3-7 days of therapy with either
montelukast (5mg or 10 mg capsule) or placebo tablets. After 3-7 days of therapy the
patients will be crossed over to receive the alternative therapy. Exercise challenges will
be completed at screening, baseline, visit 3 and visit 4. All patients will have an
albuterol metered-dose inhaler (MDI) to be used on an as needed basis for asthma symptoms.
