AZMATICS: AZithroMycin/Asthma Trial In Community Settings

Summary

The purpose of this study is to assess the effectiveness of the azalide macrolide azithromycin in adults with persistent asthma. Research Question: Will a 12-week treatment with the antibiotic, azithromycin, result in a statistically significant and clinically meaningful improvement in overall asthma symptoms and other patient-oriented asthma outcomes one year after initiation of treatment of adult primary care patients with asthma? Experimental Design: The investigators propose a one-year randomized, placebo-controlled, blinded (investigator, patient, data collector, data analyst) trial of 12 weekly doses of azithromycin/placebo as adjunctive therapy (in addition to usual care) along with a parallel observational cohort who will participate 'open label' in 100 adult asthma patients recruited from practice-based research networks (e.g., Wisconsin Research and Education Network (WREN) and others). This "practical clinical trial" will (1) enroll a representative sample of asthma patients encountered in the practices of primary care physicians, (2) employ standard clinical trial methodology to ensure internally valid results and (3) measure outcomes important to patients, so that the results will be valid and applicable to the kinds of asthma patients encountered by family physicians and other primary care providers.
