7. Human immunodeficiency virus positive or has other uncontrolled active infections(e.g. bacteria, viruses, or fungi)
8. Drug hypersensitivity to Rituximab or anaphylaxis history (including active products or additives)

Except in case of positive surface antigen B or positive hepatitis B virus polymerase chain reaction. If hepatitis B core antibody positive and hepatitis B surface antigen, hepatitis B virus polymerase chain reaction negative, proper virus preventive treatment should be taken during the study period.
20. Patients with hepatitis C antibody positive need negative hepatitis virus polymerase chain reaction results. Except for those who are positive for hepatitis C virus polymerase chain reaction.
