Testing a new injection to control hard-to-treat eosinophilic asthma

This trial is testing benralizumab, an injectable medication, to see if it can help control asthma better in people who have a type of asthma linked to high eosinophil levels (a type of white blood cell). You would receive either this medication alongside your current medium-dose inhaled steroids, or you would switch to a higher dose of inhaled steroids. The study will compare which approach works better at preventing asthma attacks and improving how you feel.

Some people with eosinophilic asthma don't improve enough when doctors increase their inhaled steroid doses. This trial exists to see whether this medication could be a better option than simply using higher doses of steroids, potentially offering better control with fewer side effects.
