About the StudyThe study was a double blind, placebo controlled, parallel group Phase 2 trial conducted at 23 sites in the United States. The study enrolled 93 adult patients with persistent mild to moderate asthma that were being treated with inhaled corticosteroids, and 90 patients completed the study. The study design provided for a four-week wash-out period during which patients received a low-dose inhaled corticosteroid while discontinuing their current asthma medication (other than permitted rescue mediation). Patients were then randomized into one of two cohorts and received either placebo or oral TC-6987 once daily, together with the low-dose inhaled corticosteroid, for four weeks. Patients in the TC-6987 cohort received a 100mg dose the first day of dosing and then a 50mg dose for the remainder of the dosing period. The study concluded with a two-week follow-up period.
