Study Arms (2)
1
EXPERIMENTALExperimental drug = rituximab for maintenance
2
ACTIVE COMPARATORComparator drug = azathioprine for maintenance
Interventions
rituximab infusion will be performed at J1, J15, M6, M12 and M18(i.e. a total of 5 infusions), at the dose of 500 mg at a fixed dosage. All patients received corticosteroids, starting from induction with prednisone (or equivalent) at a dose of 1 mg/kg/day with gradual tapering according to a regimen adjusted to body weight over a mean of 18 months since diagnosis.
azathioprine (2 mg/kg/d) for 12 months, then progressively tapered until its discontinuation at month 22. All patients received corticosteroids, starting from induction with prednisone (or equivalent) at a dose of 1 mg/kg/day with gradual tapering according to a regimen adjusted to body weight over a mean of 18 months since diagnosis.
Eligibility Criteria
You may qualify if:
- Wegener's granulomatosis Or microscopic polyangiitis complying Or kidney-limited disease With or without detectable ANCA (anti-neutrophil cytoplasmic antibodies) at the time of diagnosis or relapse, and at remission.
- Who have achieved remission using a treatment combining corticosteroids and an immunosuppressive agent according to current French guideline, including corticosteroids, cyclophosphamide IV or oral (the use of another immunosuppressant is allowed, according to the current French guidelines, as well as plasma exchanges and/or IV immunoglobulins).
- Interval of 1 month between the end of the immunosuppressant treatment and the randomization time
- Age \> 18 years and \< 75 years when the diagnosis is confirmed.
- Informed and having signed the consent form to take part in the study.
You may not qualify if:
- Other systemic vasculitis
- Secondary vasculitis (following neoplastic disease or an infection in particular)·
- Induction treatment with a regimen not corresponding to that recommended in France.
- Patient who has not achieved remission.·
- Patient who has already received a treatment by biological agents (monoclonal antibody - antiCD20 or antiTNFα).
- Incapacity or refusal to understand or sign the informed consent form.
- Incapacity or refusal to adhere to treatment or perform the follow-up examinations required by the study. Non-compliance·
- Allergy, documented hypersensitivity or contraindication to the study medication (cyclophosphamide, corticosteroids, azathioprine, rituximab),
- History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies.
- Patients receiving allopurinol cannot be included if the allopurinol must absolutely be maintained.
- Pregnancy, breastfeeding. Women of childbearing age must use a reliable method of contraception throughout the duration of immunosuppressive treatment up to 1 year after the last infusion of rituximab
- Infection by HIV, HCV or HBV
- Progressive, uncontrolled infection requiring a prolonged treatment (tuberculosis, HIV infection, etc.).
- Severe infection declared during the 3 months before randomization (CMV, HBV, HHV8, HCV, HIV, tuberculosis).
- Progressive cancer or malignant blood disease diagnosed during the 5 years before the diagnosis of vasculitis. Patients suffering from non-metastatic prostate cancer or those cured of a cancer or a malignant blood disorder for more than 5 years and not taking any antineoplastic agents for more than 5 years may be included.
