About
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.
Full 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. Although, due to the Covid-19 pandemic this may be an extended time frame for some subject visits. The study also includes a post-treatment follow-up period of 12 weeks.
