Summary

This trial will help assess the effect of benralizumab on structural and lung function changes in severe asthmatics over a 48-week period.

Who is the study for?
Adults aged 18-70 with severe eosinophilic asthma, not well-controlled despite using inhaled steroids and long-acting beta agonists. They must have specific levels of blood eosinophils and less than 12 asthma attacks in the past six months. Excluded are those who've had certain treatments like benralizumab or bronchial thermoplasty recently, current smokers, cancer patients, pregnant women, or those on immunosuppressants.
What is being tested?
The trial is testing if benralizumab can improve lung structure and function over a 48-week period compared to a placebo in patients with severe eosinophilic asthma. Participants will be monitored for changes after treatment and during a four-week follow-up.
What are the potential side effects?
While not specified here, common side effects of benralizumab may include headache, sore throat, fever; rare but serious effects could involve allergic reactions or worsening breathing problems.

Treatment Details

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
The change in airway wall area percentage as the overall median for airway generations 3 and 4 combined as measured by quantitative computed tomography (QCT) imaging
The change in eosinophil numbers expressed as number/mm2 in submucosa as measured by major basic protein (MBP) staining in endobronchial biopsies
Secondary study objectives
Absolute change from baseline to End of Treatment in mucus score assessed using computed tomography (CT) scans
Absolute change in R5-R20 (peripheral airway resistance defined as the difference in resistance between 5 Hz [R5, total respiratory system resistance] and 20 Hz [R20, central resistance]) as measured by airwave oscillometry (AO)
Lung
+32 more
Other study objectives
The number of Adverse events (AEs)/serious adverse events (SAEs).
