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

Clinical Trial ID: NCT02947945


Reslizumab 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, reslizumab, is not yet approved for doctors to treat patients with EGPA. It is considered an experimental drug in this study.

This study is open-label which means that all subjects will receive the study medication. The study medicine - reslizumab - will be given to the participants 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 (the study doctor will tell the participants which medications these are) - this is what is meant by 'standard of care' and can vary in different countries. 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 study drug affects the human body and health will be collected through a number of tests, procedures and questions. The study medicine, reslizumab, will be given to the participants at a dose of 3mg/kg intravenously (within a vein) every four weeks for 28 weeks for a total of 7 treatments. During the treatment phase of this study, a study staff member will call the participants every two weeks 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 11 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 the dose of oral steroids may be reduced during the study).


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: - A biopsy showing histopathological evidence of eosinophilic vasculitis, or perivascular eosinophilic infiltration, or eosinophil-rich granulomatous inflammation; - Neuropathy, mono or poly (motor deficit or nerve conduction abnormality); - Pulmonary infiltrates, non-fixed; - Sino-nasal abnormality; - Cardiomyopathy (established by echocardiography or MRI); - Glomerulonephritis (haematuria, red cell casts, proteinuria); - Alveolar haemorrhage (by bronchoalveolar lavage); - Palpable purpura; - ANCA positive (MPO or PR3). - Subjects who have received a cyclophosphamide (CYC) induction regimen may be included a minimum of 2 weeks after the last dose of daily oral CYC, or 3 weeks after the last dose of pulsed IV CYC prior to visit 1, if their total WBC is ≥4x109/L prior to visit 1. - 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 1. - 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 1. - 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 1 and during the study (dose reductions for safety reasons will be permitted). - Female subjects: To be eligible for entry into the study, females of childbearing potential (FCBP) must commit to consistent and correct use of an acceptable method of birth control beginning with consent, for the duration of the trial. Exclusion Criteria: - Hypereosinophilic Syndrome - Wegener's Granulomatosis - Malignancy - Parasitic disease - Pregnant or nursing - If female and of child-bearing potential, must have negative pregnancy test and must adhere to acceptable method of contraception (with <1% failure rate) during the study and for four months after the study. - Any other medical illness that precludes study involvement - Patients who are currently receiving or have previously received reslizumab or any other type of anti-interleukin therapy (i.e. mepolizumab, lebrikizumab etc.) within the last three months. - Taking cyclophosphamide - Any patients with a known hypersensitivity to reslizumab or any of its excipients
