Exclusion criteria

History of anaphylactic reaction following exposure to humanized monoclonal antibodies
Previous allogeneic transplantation
Treatment with any other investigational agent or participating in another trial within 30 days prior to entering this study
History of other malignancy or chemotherapy radiotherapy for any neoplastic disease other than WM prior to the study.

Patients with positive serology should be referred to a hepatologist or gastroenterologist before start of treatment and should be monitored and managed following local standards to prevent hepatitis reactivation. Furthermore transaminases and HBV DNA quantification must be tested at weeks 4 and 8 after treatment start. Then transaminases must be tested at week 12 of treatment start.
