Brief Summary: The purpose of this trial is to determine whether regularly scheduled use of an inhaled long-acting beta agonist salmeterol in the setting of concomitant use of inhaled corticosteroids beclomethasone hydroflouroalkane HFA inhaler will have a detrimental effect on asthma control in people who bear the B16-ArgArg genotype of the beta-2 adrenergic receptor gene as compared to people with asthma of similar severity who bear the B16-GlyGly genotype
Detailed Description: BACKGROUND

The purpose of this study is to compare the effects of a long-acting beta agonist in patients with asthma receiving inhaled corticosteroids who express two distinct polymorphisms of the beta-2 adrenergic receptor

DESIGN NARRATIVE

Participants were homozygous for arginine or glycine at the 16th amino-acid position of the β-2 adrenergic receptor B16 ArgArg or B16 GlyGly Individuals were matched against their opposite genotype by forced expiratory volume in one second FEV1 and race Matched participants entered an 8-week run-in period This is a 62-week crossover design where subjects receive the following therapies

Beclomethasone HFA 240 µg twice a day BID as-needed PRN albuterol 8-week run-in
Beclomethasone HFA 240 µg BID salmeterol 50 µg BID PRN ipratropium bromide PRN albuterol 18-week treatment period
Beclomethasone HFA 240 µg BID PRN albuterol 8-week run-out
Beclomethasone HFA 240 µg BID placebo salmeterol PRN ipratropium bromide PRN albuterol 18-week treatment period
Beclomethasone HFA 240 µg BID PRN albuterol 10-week run-out

The order of treatments received during the two treatment periods is randomized
