Tralokinumab is a human monoclonal antibody that neutralises interleukin 13. We aimed to evaluate whether tralokinumab would have an effect on airway eosinophilic infiltration, blood and sputum eosinophil concentrations, eosinophil activation, and airway remodelling. Methods We did a multicentre, double-blind, randomised, placebo-controlled phase 2 trial at 15 centres across the UK, Denmark, and Canada. We enrolled participants of either sex aged 18–75 years with inadequately controlled moderate-to-severe asthma for 12 months or more, requiring treatment with inhaled corticosteroids at a stable dose. We randomly assigned participants (1:1) to receive tralokinumab (300 mg) or placebo by an interactive web-based system or voice response system. Participants and study personnel were masked to treatment allocation. Both tralokinumab and placebo were administered subcutaneously every 2 weeks. The primary outcome measure was ch...
