Summary

This study measured the amount of mepolizumab in the blood of 50 adults with severe asthma who were already taking the drug. Researchers compared drug levels between those who responded well to treatment and those who did not. The goal was to see if differences in how the body processes the drug could explain why some patients don't get better. This was an observational study, not a test of a new treatment.
