• History of primary immunodeficiency, organ, or allogeneic bone marrow transplant;
• Patients must be seronegative for hepatitis B surface antigen;
• Patients must be seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then patients must be tested for the presence of viremia by RT-PCR and must be HCV RNA negative;
• History of positive HIV or positive HIV at screening;
• Active tuberculosis or positive QuantiFERON test at screening;
• Any other laboratory abnormality that, in the opinion of the investigator, may jeopardize the subject's ability to participate in the study; 23.
