Summary

Asthma is a chronic inflammatory disorder of the airways with a variety of inflammatory processes contributing to the pathogenesis. The inflammation leads to a state of increased airway responsiveness and reversible airway obstruction that causes the recurrent symptoms of asthma. Despite the variety of treatments available for asthma, none are curative, and the disease continues to place a burden on society in terms of morbidity, reduced quality of life (QOL), and ever increasing healthcare costs. The prevalence of asthma continues to increase with current data suggesting that since 1980, adult asthma cases have increased by 75% and in children under 5 years of age the prevalence has increased by 160%.1 Additionally, studies have suggested that the disease severity has been underestimated and that more patients may be classified as having moderate to severe persistent disease.2 Inhaled corticosteroids (ICS) have been the cornerstone of anti-inflammatory treatment for decades and have been shown to improve lung function, decrease symptoms, and reduce asthma exacerbations.3 However, many patients are still inadequately controlled despite treatment according to current asthma management guidelines and have a significant unmet medical need. Such patients are at high risk of serious exacerbations and asthma-related mortality.4 Combining long-acting β2-agonists (LABAs) with low dose ICS has been shown to improve asthma control over using higher doses of ICS alone. However, LABAs act mainly at the bottom of the inflammatory cascade and there are concerns that they may mask underlying inflammation.5 Recently, leukotriene receptor antagonists have been added to ICS as second-line therapy in the management of asthma. Zileuton has been extensively studied in inflammatory diseases such as asthma, in which leukotrienes mediate inflammation.

The aim of this study is to assess the effect of zileuton controlled-release (CR; 1200 mg 2-times daily \[BID\]) on pulmonary function, asthma control, and symptomatic response in adult patients with asthma poorly controlled on moderate dose ICS.
