This is a multicentre, randomised, double-blind, placebo controlled, parallel group study designed to evaluate the efficacy and safety of tezepelumab in reducing oral corticosteroid use in adults with oral corticosteroid dependent asthma treated with maintenance OCS in combination with high dose inhaled corticosteroids (ICS) and long-acting β2 agonists (LABA), with or without other asthma controller therapies. Approximately 207 subjects will be randomized globally. Subjects will receive tezepelumab, or placebo, administered via subcutaneous injection using the accessorized pre-filled syringe (APFS), over a 28-week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.
