Moderate to Persistent Asthma in the Obese Subject

Asthma Clinical Trial

Official title: A Randomized, Double-Blind, Placebo-Controlled, Cross-over Study to Evaluate the Effect of the Leukotriene Antagonist (Singulair©) Plus Moderate Dose Beclomethasone Compared to High Dose Beclomethasone in Obese Subjects With Moderate Persistent Asthma

Status Terminated

Clinical Trial Summary

Obesity is associated with increased airway inflammation and asthma severity that results in suboptimal control of asthma despite therapy with high dose inhaled corticosteroids (ICS). The investigators suggested that the addition of Singular (montelukast)[LTRA] to moderate doses of inhaled corticosteroids will improve asthma control. This cross over study will be treat subjects with moderate dose ICS/LTRA for 12 weeks and high dose ICS with placebo for 12 weeks.

Clinical Trial Description

Subjects will enter the 2-week run-in period after meeting eligibility criteria at the screening visit (visit 1). During run-in subjects will have all usual asthma medications discontinued and will be placed on inhaled corticosteroids at moderate doses and leukotriene receptor antagonists will be withdrawn (LTRA wash-out). Subjects will be monitored to rule out any acute infection or symptoms consistent with an exacerbation. The run-in period will be used to assess subject compliance and understanding of study related procedures. Following the run-in, to be eligible for the randomization subjects must have an ACQ score >1.25 on the Juniper Asthma Control Questionnaire. ;
