5) Concurrent chemotherapy, radiotherapy, or immunotherapy, including other monoclonal antibodies. Localized radiotherapy to an area not compromising bone marrow function does not apply.

6) Any serious medical condition, laboratory abnormality, or psychiatric illness that places the subject at unacceptable risk if he/she were to participate in the study.
7) Any known hypersensitivity to ofatumumab or its components. |
