Description

A Multicentre, Randomized, Double-Blind, Placebo Controlled, Parallel Group, Phase 3 Study to Evaluate the Efficacy and Safety of Tezepelumab in Adults and Adolescents with Severe Uncontrolled Asthma

This is a multicentre, randomized, double-blind, placebo controlled, parallel group study designed to evaluate the efficacy and safety of tezepelumab in adults and adolescents with severe, uncontrolled asthma on medium to high-dose ICS and at least one additional asthma controller medication with or without OCS. Approximately 1060 subjects will be randomized globally. Subjects will receive tezepelumab, or placebo, administered via subcutaneous injection at the study site, over a 52-week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.
