A Study Evaluating the Efficacy and Safety of Lebrikizumab in Adult Patients With Mild to Moderate Asthma

CompletedPhase 3

Sponsor: Hoffmann-La Roche

Conditions: Asthma

Interventions: Lebrikizumab, Montelukast, Placebo

Countries: United States, Brazil, Bulgaria, Canada, Czechia, New Zealand, Poland, Romania

This Phase III, randomized, double-blind, placebo-controlled, multicenter study will assess the efficacy and safety of lebrikizumab in adult patients with mild to moderate asthma treated with short-acting beta-agonist (SABA) therapy alone. Patients will be randomized in a 1:1:1 ratio to receive either blinded lebrikizumab or placebo treatment by subcutaneous (SC) injection (every 4 weeks for a total of 3 doses) or open-label treatment with Singulair (Montelukast; 10 mg daily). Time on study treatment will last 12 weeks.
