Benralizumab in the Treatment of Eosinophilic Granulomatosis With Polyangiitis (EGPA) Study

Study Purpose

Benralizumab is a type of medicine called a monoclonal antibody that is made in the research clinic; it works by blocking a specific protein in the body called interleukin-5. The study medicine, benralizumab, is not yet approved for doctors to treat patients with EGPA. It is considered an experimental drug in this study.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Women will be considered postmenopausal if they have been amenorrheic for 12 months prior to the planned date of visit -1 without an alternative medical cause. The following age-specific requirements apply:
  • - Women <50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and follicle stimulating hormone (FSH) levels in the postmenopausal range.
  • - Women ≥50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.

Additional Details

This study is open-label which means that all subjects will receive the study medication. The medicine-benralizumab-will be given to subjects in addition to the medicines they are already taking to treat their EGPA such as oral steroids (e.g. prednisone) and medicines that reduce the activity of their immune system. Drugs that are sometimes used (i.e., standard of care) to reduce the activity of the immune system in EGPA (in addition to oral steroids) include azathioprine, methotrexate, mycophenolate mofetil and cyclophosphamide. Information about how the stud drug that you get affects the subjects body and their health will be collected through a number of tests, procedures and questions. The study medicine, benralizumab, will be given to subjects as one injection 30 mg under skin every four weeks for 12 weeks and then every 8 weeks for 16 weeks for a total of 5 treatments. During the treatment phase of this study, a study staff member will call the subjects to see how they are doing, what medications they are taking and if they are able to decrease their steroid use. The study is a total of 9 study visits in a 44 week time period. Everyone who takes part in the study will continue to receive his/her existing treatments for EGPA (although their dose of oral steroids may be reduced during the study.
