Study summary

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

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Capable of giving signed , which includes compliance with the requirements and restrictions listed in the ICF.
  2. At least 18 years of age at the time of signing the informed consent at Visit 1.
  3. Documented asthma diagnosis ≥12 months prior to Visit 1. This may be documented by physician-diagnosis or by documented pharmacy records.
  4. Treated with a daily ICS-containing maintenance inhaler for asthma at a stable dose for ≥3 months prior to Visit 1. This inhaler may contain ICS alone, or in combination with a LABA or LABA-LAMA. The prescribed inhaler must be compatible with a study-provided EMM (see Appendix A).
  5. Prescribed a SABA-containing reliever inhaler, AND willing to use study-provided ICS-SABA reliever with EMM provided by the study.
  6. Prescribed benralizumab for severe eosinophilic asthma for ≥6 months AND has had ≥4 benralizumab doses (3 loading doses + at least 1 8-week dosing interval).

Exclusion criteria

Exclusion Criteria:

  1. Current smoker (including tobacco, vaping, and marijuana). Former smokers must have stopped ≥6 months prior to Visit 1.
  2. Has a known, preexisting, cardiac, endocrine, , 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.
  3. History of use of any biologic therapy for asthma (other than benralizumab) within 5 half-lives or 5 months, whichever is longer, before Visit 1.
  4. 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 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
    • An emergency department visit (defined as evaluation and treatment for \<24 hours in an emergency department or urgent care) due to asthma that required systemic corticosteroids (as per above)
  5. Current enrollment in an asthma-related clinical trial.
  6. Any known history of adverse reactions to budesonide-albuterol.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2026 (actual). Primary completion is estimated for Sep 2027, 14 months after the start.

Of 90 non-industry phase 4 interventional studies under Asthma, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 41. This study's planned 14 months is below that.

Counting every sponsor, half of 156 studies reached it within 24 months; a quarter within 11 and three quarters within 37.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 15, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
