Phase 3 Trial of Tezepelumab Compared With Placebo in Children Ages 5 to Under 12 With Severe Uncontrolled Asthma

What this Trial Is About

Researchers are evaluating the safety and effectiveness of tezepelumab in children aged 5 to under 12 years with severe uncontrolled asthma. These children are already on medium to high doses of inhaled corticosteroids and at least one other asthma controller medication. The study is a phase 3, randomized, double-blind, placebo-controlled trial aimed at assessing tezepelumabs impact on asthma control and safety in this pediatric population. Participants will be randomly assigned in a 21 ratio to receive either subcutaneous injections of tezepelumab or a matching placebo over a 52-week double-blind treatment period. Before this, there is a 4 to 6 week screening and run-in period. After the treatment phase, there is a 12-week off-treatment follow-up for those not continuing. Additionally, an optional 104-week open-label extension allows eligible participants to receive tezepelumab, followed by another 12-week post-treatment follow-up. Throughout the study, participants will undergo regular assessments including lung function tests, asthma control questionnaires, symptom diaries, and blood tests to measure inflammation and immune response. Researchers will monitor asthma exacerbations, medication use, quality of life, and any side effects. Safety will be tracked during treatment and follow-up periods, with total study involvement potentially lasting over three years for those in the extension phase.
