How well does this asthma medication work in real patients

The ATHENA study is tracking how benralizumab works in real-world practice for adults with severe eosinophilic asthma—the kind of asthma driven by high levels of a specific white blood cell called eosinophils. Researchers want to learn whether this medication helps patients achieve remission (where asthma is well-controlled or nearly symptom-free) and how it changes the immune system. By collecting information from patients actually being treated with the medication, the study will provide practical evidence about its effectiveness and long-term safety.

Current research on this medication has mostly come from controlled clinical trials, but doctors need to understand how well it works for real patients in everyday practice—patients who may be older, have other health conditions, or take other medications. This study aims to fill that gap and help doctors better predict which patients will benefit most from this treatment.
