Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the long-term safety performance of fexofenadine compared to montelukast in subjects with asthma

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The incidence of respiratory allergy in the US has increased gradually over the past several years, and current estimates suggest that allergic rhinitis and bronchial asthma affect approximately 20% and 5% of the population, respectively. Rhinitis and asthma frequently coexist, and large-scale population surveys indicate that up to 38% of subjects with rhinitis have asthma, and up to 78% of subjects with asthma have chronic nasal symptoms. Safety concerns with the increased use of inhaled corticosteroids, the heterogeneity of the disease, and poor compliance with asthma medication regimens, point to the need for the development of safe and convenient oral therapies for asthma. Oral leukotriene receptor antagonists (eg montelukast) are the latest class of inflammation-modulating asthma drugs and appear to cause fewer long-term side effects than systemic corticosteroids and reduce the need for shorter-acting bronchodilator reliever medicines. However variability in response between patients has been observed and clinical experience with these agents is still limited.

Histamine is an important chemical mediator of inflammation in asthma. The benefits of antihistamine treatment in patients with mild to moderate asthma have been well documented, however their clinical use has been previously limited due to the high doses required for efficacy and their associated side effects including sedation and cognitive impairment. Recent evidence indicates that in addition to H1-receptor antagonism, some of the newer nonsedating, non-impairing antihistamines appear to possess various anti-inflammatory properties at concentrations achieved at therapeutic dosages suggesting an additional benefit of these drugs in the management of allergic diseases and asthma. The purpose of this study is to assess the long-term safety performance of fexofenadine compared to montelukast in subjects with asthma.

Inclusion Criteria

* Males and non-pregnant, non-breastfeeding females 12 through 80 years of age
* FEV1 in the context of this study is greater than 40% and not less or equal to 87% of predicted values for subjects not currently taking ICS and greater than 40% and not less or equal to 95% for those subjects taking ICS at Visit 1 and/or Visit 2 (and no albuterol use within 6 hours prior to spirometry)
* Improvement in FEV1 of at least 12% of predicted value and at least 200ml within 15 to 30 minutes of inhaling 2 puffs of albuterol 90mcg/actuation demonstrated at study entry OR documented during the previous 12 months at the study site.
* Use of a short-acting, beta-agonist inhaler to treat asthma symptoms on an average of at least 2 days per week during the previous 2 weeks (greater than or equal to 4 days total during the previous 2 weeks, excluding prophylactic use).
