Study to Evaluate Tezepelumab on Airway Inflammation in Adults With Uncontrolled Asthma (CASCADE) (CASCADE)

Brief Summary:
A phase 2, multicentre, randomized, double-blind, placebo-controlled, parallel group study to evaluate the effect of tezepelumab on airway inflammation in adults with inadequately controlled asthma.

Detailed Description:
This is a multicentre, randomized, double-blind, placebo-controlled, parallel group study to evaluate the effect of tezepelumab on airway inflammation in adults with inadequately controlled moderate-to-severe asthma, taking inhaled corticosteroids and at least one additional asthma controller. Approximately 110 subjects will be randomized globally. Subjects will receive tezepelumab, or placebo, administered via subcutaneous injection at the study site, over a 28-week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.
