Study of Benralizumab Injections Added to Medium-Dose Inhaled Therapy for People Aged 12 to 75 With Difficult-to-Control Eosinophilic Asthma

What this Trial Is About

This trial investigates the efficacy and safety of benralizumab as an additional treatment for people aged 12 to 75 with uncontrolled eosinophilic asthma. These participants are already treated with a medium-dose inhaled corticosteroid and long-acting beta2-agonist ICS-LABA. The study compares adding benralizumab to increasing the inhaled therapy to a higher dose ICS-LABA. The research is a randomized, double-blind, active-controlled phase 3b trial designed to evaluate these treatments in people with a history of eosinophilic asthma who remain uncontrolled on medium-dose ICS-LABA with or without other controllers except oral corticosteroids. Participants are randomly assigned to one of two groups one receives benralizumab 30 mg by subcutaneous injection along with medium-dose ICS-LABA, and the other receives a placebo injection plus high-dose ICS-LABA. Doses of benralizumab or placebo are given every 4 weeks for the first three doses, then every 8 weeks, with up to seven injections during the study. The study treatment schedules continue for 48 weeks. During the study, participants will undergo assessments including lung function tests, asthma control questionnaires, and quality of life surveys. Researchers will track the annual rate of asthma exacerbations, time to first exacerbation, and safety events throughout the 48-week period. Compliance with asthma controller medication is monitored via daily diaries. This comprehensive evaluation helps understand the impact of adding benralizumab compared to increasing inhaled therapy dose in uncontrolled eosinophilic asthma.
