Summary

This trial will test if a drug can help kids with severe asthma better manage their condition.

Who is the study for?
This trial is for children aged 5 to less than 12 with severe asthma, who are already on medium to high-dose inhaled corticosteroids and another asthma controller. They must have had at least two serious flare-ups or one hospitalizing event in the past year, weigh over 16 kg, and show certain levels of lung function.
What is being tested?
The study tests Tezepelumab's effectiveness and safety against a placebo in managing severe asthma in kids. Participants will be randomly assigned to receive either Tezepelumab or a placebo alongside their standard asthma treatments.
What are the potential side effects?
While specific side effects for Tezepelumab aren't listed here, common ones may include reactions at the injection site, headache, fatigue, and potential worsening of asthma symptoms.
