About This Trial

This study evaluates the efficacy and safety of benralizumab as an add-on therapy in uncontrolled eosinophilic asthma participants treated with medium-dose ICS-LABA compared to the conventional treatment step of escalation of inhaled therapy to high-dose ICS-LABA.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Eosinophilic Asthma, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 400 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Who May Be Eligible (Plain English)

Who May Qualify: - Written willing to sign a consent form - Participant must be 12 to 75 years of age - Documented history of physician-diagnosed asthma requiring treatment with at least medium-dose ICS (\> 250 μg fluticasone dry powder formulation equivalents total daily dose) and a LABA, for at least 12 months prior to Visit (V) 1. - Documented treatment with medium-dose ICS and LABA for at least 3 months prior to Visit 1 with or without additional asthma controllers (excluding oral corticosteroids). - Weight of ≥ 35 kg. - Pre-Bronchodilator (BD) Forced expiratory volume in 1 second (FEV1) of ≤ 90% predicted - Documented at least 2 asthma exacerbations in the 12 months prior to the date of willing to sign a consent form. - ACQ-6 score ≥ 1.5 at Visit 1, plus at least once in the run-in period (from V2 to V3) and at V3. - Evidence of asthma as documented by excessive variability in lung function, as defined in the protocol. - Peripheral blood eosinophil count of ≥ 150 cells/μL, as defined in the protocol. - At least 70% compliance with usual asthma controller ICS-LABA during run-in period (from Visit 2 to Visit 3) based on asthma daily diary. Who Should NOT Join This Trial: - Important pulmonary disease other than asthma at the discretion of the investigator, or ever been diagnosed with pulmonary or systemic disease, other than asthma, which are associated with elevated peripheral eosinophil counts. - Asthma exacerbation requiring use of Systemic corticosteroids (SCS), or acute upper/lower respiratory infection that requires antibiotics or antiviral medication within 30 days prior to the date willing to sign a consent form is obtained or during the screening/run-in period - Any unstable disorder that in the opinion of the investigator could affect the study according to the study protocol. - Clinically significant chronic or ongoing active infections requiring systemic treatment (at investigator's discretion) ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT06750289), the sponsor (AstraZeneca), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions? See our 25 questions to ask about clinical trials guide for a more complete checklist.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
