- Has a known, preexisting, clinically significant cardiac, endocrine, autoimmune, metabolic, neurological, renal, gastrointestinal, hepatic, hematological, or any other system abnormalities that are uncontrolled with standard treatment, which, in the investigator's opinion, would compromise the participant's safety, interfere with the interpretation of the study results or otherwise preclude participation or protocol adherence.

- A severe asthma exacerbation within 4 weeks of Visit 1. For this study, a severe asthma exacerbation is defined as an episode of worsening asthma symptoms that result in at least one of the following:
- Use of systemic corticosteroids for at least 3 consecutive days (or a single depo-injectable dose of corticosteroids)
- An inpatient hospitalization (defined as admission to an inpatient facility and/or evaluation and treatment in a healthcare facility for ≥24 hours) due to asthma

About this study
Official title: Fasenra Demonstrates Durability Over the Full 8-week Treatment Period
The goal of this observational study is to learn more about the effectiveness of benralizumab (Fasenra, 30 mg every 8 weeks) in maintaining asthma control in people with severe eosinophilic asthma.
Participants will have electronic medication monitors fitted to their usual maintenance inhaler, as well as a study-provided anti-inflammatory rescue inhaler, albuterol-budesonide (AirSupra). These monitors will track when each inhaler is used. Participants will also upload time-stamped photos of their benralizumab administration to their electronic medical records.
Read the detailed description
This will be a 26-week prospective, single arm study. At Visit 1 (in-person visit at day -14), scheduled two weeks before they are due for their next dose of benralizumab, participants will provide informed consent, demographics information, and have Adherium electronic medication monitors (EMM) fitted onto their inhaled corticosteroid (ICS)-containing maintenance and inhaled corticosteroid-short-acting β2-agonist (ICS-SABA) reliever medications . The patient-facing research assistant (pRA) will ask participants for the dates they plan to administer each of the following three doses of benralizumab, at 8-week intervals (±7 days), and schedule video visits two, three, and four on those dates to confirm the patient received the benralizumab. If the patient cannot complete a video visit for directly observed therapy of benralizumab administration, they can also upload a time and date stamped photo of themselves administering the benralizumab to their EMR via the MyChart Patient Portal within 48 hours of administration. Participants will continue usual care with their asthma health care professional, and the study team will collect any interval Asthma Control Test (ACT), spirometry (e.g., forced exhalation volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC), and fractional exhaled nitric oxide (FENO) measurements, as well as oral corticosteroid (OCS) use (both OCS bursts and changes in daily OCS dose, as applicable), immediate care visits, emergency department (ED) visits, and hospitalizations for asthma.
The pRA will perform all of their tasks under the supervision of the study investigators (an allergist and immunologist and a pulmonologist). At visit one, the pRA will teach each participant how to: attach the Adherium EMM to their ICS-SABA reliever and ICS-containing maintenance medications; download the Adherium asthma App to their smartphone; pair the EMM with their smartphone App; and view their ICS adherence and ICS-SABA usage, as well as inhalation quality, on the App. Each month, under the supervision of the study investigators, the pRA will review the remote therapeutic monitoring data for each participant's ICS-SABA reliever and ICS-containing maintenance medications and document the results of this review in the patient's chart.
Data collected during the study include:
- Maintenance inhaler use
- Rescue inhaler use
- Dates of benralizumab administration
- Dates of severe asthma exacerbations
- Oral corticosteroid use
- Healthcare visits for asthma
- AIRQ scores
- Results from standard of care assessments, including ACT scores, lung function values, FeNO, and absolute eosinophil counts
- Demographic information, including age, gender, race, ethnicity, and insurance
- Conditions
- Eosinophilic Asthma, Severe Asthma, Severe Eosinophilic Asthma, Asthma
- Being tested
- Budesonide-albuterol, Benralizumab

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Budesonide-albuterol and Benralizumab in people with Eosinophilic Asthma and Severe Asthma, run by Endeavor Health at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: enrolling by invitation, as of the sponsor's last update on 15 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in anti-inflammatory reliever inhaler use during last benralizumab dosing cycle (time frame: Weeks 17 through 24). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2026.
