Summary:

      It has been shown that many patients with lymphoma or chronic lymphocytic leukemia (CLL)have
      low levels of complement. Several drugs have been approved by the Food and Drug
      Administration (FDA) for use in this cancer. However, these drugs are often used as
      combination therapies which means two or more drugs are part of the treatment. Many people,
      especially elderly patients, cannot put up with the use of multiple drugs because of the side
      effects.

      The main purpose of this study is to see if patients respond to therapy with human plasma
      (known as fresh frozen plasma or FFP) and ofatumumab. Another purpose of the study is to find
      out if this therapy will increase chances of getting rid of leukemia. This study will also
      look at the levels of complement in your blood. The levels of complement may allow better
      understanding of whether increasing the levels of complement by giving FFP may help control
      leukemia.

               -  Alkaline phosphatase <2.5 times upper limit of normal (unless due to disease
                  involvement of the liver or bone marrow)

          -  Patients must be at least 18 years of age.

          -  Patients must have a performance status of 0-2 by ECOG criteria.

          -  All patients must be informed of the investigational nature of this study and must
             sign and give written consent in accordance with institutional and federal guidelines.

        Exclusion Criteria:

          -  Subjects who have current active hepatic or biliary disease.

          -  Having received rituximab or rituximab-containing therapy within the prior 3 months.

          -  Treatment with any known therapeutic or experimental therapy within 4 weeks prior to
             enrollment, or currently participating in any other interventional clinical study.

          -  Other past or current malignancy.

          -  Prior treatment with anti-CD20 monoclonal antibody or alemtuzumab within 3 months
             prior to start of therapy.

          -  Chronic or current infectious disease requiring systemic antibiotics, antifungal, or
             antiviral treatment such as, but not limited to, chronic renal infection, chronic
             chest infection with bronchiectasis, tuberculosis and active Hepatitis C.

          -  History of significant cerebrovascular disease in the past 6 months or ongoing event
             with active symptoms or sequelae.

          -  Known HIV positive.

          -  Clinically significant cardiac disease including unstable angina, acute myocardial
             infarction within six months prior to randomization, congestive heart failure, and
             arrhythmia unless controlled by therapy, with the exception of extra systoles or minor
             conduction abnormalities.

          -  Significant concurrent, uncontrolled medical condition including, but not limited to,
             renal, hepatic, gastrointestinal, endocrine, pulmonary, neurological, cerebral or
             psychiatric disease which in the opinion of the investigator may represent a risk for
             the patient.
