Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Asthma Drug: Benralizumab Phase 2

Detailed Description:

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.


Study Type : Interventional  (Clinical Trial)

Official Title: The Efficacy and Safety of Benralizumab In the Treatment of Eosinophilic Grandulomatosis With Polyangiitis (EGPA) Study: BITE
Actual Study Start Date : April 15, 2017
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2018


Arm Intervention/treatment
Open-Label
All subjects will receive the study medication- benralizumab
Drug: Benralizumab
one injection 30 mg under the subjects skin every 4 weeks for 8 weeks and then every 8 weeks for 24 weeks for a total of 5 treatments.




Primary Outcome Measures :
  1. All adverse events will be reported by count of events (safety and tolerability ) [ Time Frame: Up to 12 months ]
    All adverse events will be reported to AstraZeneca and the IRB in accordance with the policy of National Jewish Health and the FDA. Serious adverse events, whether or not considered related to the investigational drug, will be recorded on the SAE event form will be sent to AstraZeneca within 24 hours of submission to the FDA.


Secondary Outcome Measures :
  1. Change in corticosteroid dosage [ Time Frame: Up to 12 months ]
    Change in steroid dose will be assessed by comparing the corticosteroid dose to subjects at the end of the steroid stable phase and compare to steroid dose at the end of treatment period.

  2. Change in the rate of EGPA exacerbations during the study period. [ Time Frame: Up to 12 months ]
    Change in the rate of exacerbations will be assessed by comparing the rate of exacerbations during the study period with the rate during the washout and safety-monitoring period as well as with the self-reported rate of exacerbations from the year prior to the study.

Ages Eligible for Study:   18 Years to 100 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Informed Consent: Able to give written informed consent prior to participation in the study, which will include the ability to comply with the requirements and restrictions listed in the consent form. Subjects must be able to read, comprehend, and write at a level sufficient to complete study related materials.
  • Gender and Age: Male or female subjects >18 years old
  • EGPA diagnosis: subjects who have been diagnosed with EGPA for at least 6 months based on the history or presence of: asthma plus eosinophilia (>1.0x109/L and/or >10% of leucocytes) plus at least two of the following additional features of EGPA

    1. A biopsy showing histopathological evidence of eosinophilic vasculitis, or perivascular eosinophilic infiltration, or eosinophil-rich granulomatous inflammation;
    2. Neuropathy, mono or poly (motor deficit or nerve conduction abnormality);
    3. Pulmonary infiltrates, non-fixed;
    4. Sino-nasal abnormality;
    5. Cardiomyopathy (established by echocardiography or MRI);
    6. Glomerulonephritis (haematuria, red cell casts, proteinuria);
    7. Alveolar haemorrhage (by bronchoalveolar lavage);
    8. Palpable purpura;
    9. ANCA positive (MPO or PR3).
  • Subjects who have received cyclophosphamide can be included after a 4-week washout prior to visit 0 (first injection).
  • Subjects who have received a methotrexate, azathioprine, or mycophenolate mofetil induction regimen may be included if on a stable dose for at least 4 weeks prior to visit 0.
  • Corticosteroid therapy: Subject must be on a stable dose of oral prednisolone or prednisone of ≥5 mg/day for at least 4 weeks prior to visit 0.
  • Immunosuppressive therapy: If receiving immunosuppressive therapy (including methotrexate, azathioprine, or mycophenolate mofetil, but excluding restricted medications below) the dosage must be stable for the 4 weeks prior to visit 0 and during the study (dose reductions for safety reasons will be permitted).
