             criteria: Relapsed CLL: defined as a subject who has received at least one prior CLL
             therapy and previously achieved a complete or partial remission/response lasting at
             least 6 months.

        Exclusion Criteria:

          -  Refractory CLL: defined as treatment failure (failure to achieve a CR or PR) or

          -  Known transformation of CLL (e.g. Richter's).

          -  Known central nervous system involvement by CLL. Screening laboratory values:
             Platelets less than 100 x 109/L (unless due to CLL involvement of the bone marrow).
             Neutrophils less than 1.5 x 109/L (unless due to CLL involvement of the bone marrow).
             Serum creatinine greater than 1.5 times the upper limit of normal (ULN); subjects with
             a serum creatinine greater than 1.5 x ULN will be eligible if the calculated
             creatinine clearance [Cockcroft, 1976] is greater than or equal to 30 mL/min. Total
             bilirubin greater than 1.5 times ULN (unless due to liver involvement by CLL or

             C, and known Human Immunodeficiency Virus (HIV) disease. All HIV-positive subjects are

             Syndrome (AIDS) defining disease and/or are on antiviral therapy.

          -  Other past or current malignancy (with the exception of basal cell carcinoma of the
             skin or in situ carcinoma of the cervix or breast) unless the tumour was successfully

          -  Positive serology for Hepatitis B (HB) defined as a positive test for Hepatitis B
             surface antigen (HBsAg). In addition, if negative for HBsAg but Hepatitis B core
             antibody (HBcAb) positive, a Hepatitis B Virus (HBV) DNA test will be performed and if
             positive the subject will be excluded.

          -  Known or suspected hypersensitivity to ofatumumab or bendamustine that in the opinion
             of the investigator is a contraindication to their participation in the present study.

          -  Treatment with any known non-marketed drug substance or experimental therapy within 5
             terminal half lives or 4 Weeks prior to first study treatment dose, whichever is
             longer, or participation in any other interventional clinical study.

          -  Known or suspected inability to comply with the study protocol.

          -  Lactating women, women with a positive pregnancy test at Visit 1 or women (of
             childbearing potential) as well as men with partners of childbearing potential, who
             are not willing to use adequate contraception from study start through one year
             following last ofatumumab dose. Adequate contraception is defined as abstinence, oral
             hormonal birth control, implants of levonorgestrel, estrogenic vaginal ring,
             percutaneous contraceptive patches, intrauterine device, and male partner
             sterilisation if male partner is sole partner for that subject. For females in the
             USA, the use of a double barrier method is also considered adequate (condom or
             occlusive cap plus spermicidal agent).

               -  Subjects can participate in the study if in the opinion of the investigator it is
                  thought not to affect the subject's safety, the conduct of the study or the
                  interpretation of the data.
