  • History of asthma based upon presence of asthma symptoms such as cough, shortness of breath, wheeze or chest tightness,
  • positive skin-prick test to a House Dust Mite extract,
  • Forced expiratory volume at one second >70% predicted pre-albuterol, > 80% predicted post albuterol

  • > 20% immediate drop in FEV1 following inhaled antigen challenge.
  • Safety laboratory assessments within normal ranges (labs to include complete blood count with differential, blood urea nitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, Prothrombin time, Partial Thromboplastin Time, and platelet count)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Primary Endpoint of the Study is the Percent of Eosinophils in the Bronchoalveolar Lavage Fluid After Segmental Allergen Challenge, Before and After Mepolizumab Administration (Bronchoscopy #2 vs. Bronchoscopy #4).

    Percent of eosinophils was determined in the bronchoalveolar lavage fluid collected from the participant after segmental allergen challenge. This was done via differential cell count using Hema-3 stain. Cell differentials were determined by counting a total of 1000 cells on two cytospin preparations. The percent eosinophils were done before and after administration of mepolizumab for a specified amount of time (up to 3 months of administration).

    Measured: before and after up to 3 months of Mepo.

Secondary outcomes (1)
  1. Effect of Mepolizumab on Bronchoalveolar Lavage Fluid Concentrations of IL-5 Cytokine Before and After Mepolizumab

    IL-5 was measured via ELISA on bronchoalveolar lavage fluid before and after mepolizumab administration (up to 3 months of administration). Fluid was prepared in LowCross-Buffer to minimize potential matrix effects. A 1/2 dilution of 1X bronchoalveolar fluid was used for IL-5 detection. Data are expressed as pg/mL and are extrapolated to 1X.

    Measured: before and after up to 3 months of Mepo

Questions about this trial

What is this clinical trial studying?

A study testing mepolizumab in people with Asthma, run by University of Wisconsin, Madison 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 10 inclusion and 14 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: finished, as of the sponsor's last update on 10 Apr 2019. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Dec 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Primary Endpoint of the Study is the Percent of Eosinophils in the Bronchoalveolar Lavage Fluid After Segmental Allergen Challenge, Before and After Mepolizumab Administration (Bronchoscopy #2 vs. Bronchoscopy #4). (time frame: before and after up to 3 months of Mepo.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00802438, which also lists 1 linked publication.

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 10 Apr 2019.
