Summary

This trial is testing an injectable medication called Tezepelumab to help adults with severe asthma reduce their use of oral steroids. The medication works by reducing inflammation in the airways, which can make breathing easier. Tezepelumab has shown effectiveness in improving lung function in patients with severe, uncontrolled asthma.

Who is the study for?
Adults aged 18-80 with severe asthma, on long-term oral corticosteroids (5-40 mg of prednisone daily) for at least 3 months, and who've had an asthma exacerbation in the past year. Participants must have been on a stable steroid dose for 4 weeks prior to joining and treated with high-dose inhalers. Excluded are those with immunodeficiency, recent major surgery, other significant diseases or infections, drug abuse history within a year, previous tezepelumab use or participation in other trials.
What is being tested?
The trial is testing Tezepelumab's effectiveness and safety in reducing the need for oral steroids in adults with severe asthma. It aims to see if this treatment can help manage asthma better than current standard therapies.
What are the potential side effects?
Potential side effects of Tezepelumab may include reactions at the injection site, headaches, fatigue, and possible increased risk of infection due to its immune-modulating effects.

Other Research
Common treatments for asthma include inhaled corticosteroids (ICS), long-acting beta-agonists (LABAs), leukotriene modifiers, and monoclonal antibodies. ICS reduce inflammation by inhibiting multiple inflammatory pathways. LABAs relax airway muscles, improving airflow. Leukotriene modifiers block chemicals that cause inflammation and bronchoconstriction. Monoclonal antibodies, such as Tezepelumab, target specific molecules like thymic stromal lymphopoietin (TSLP) to reduce inflammation. This is crucial for asthma patients as it helps control symptoms, reduce exacerbations, and improve overall lung function, leading to better disease management and quality of life.
