Summary:

      This phase II trial studies how well lenalidomide and ofatumumab work in treating
      participants with previously treated chronic lymphocytic leukemia or small lymphocytic
      lymphoma. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop
      the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by
      stopping them from spreading. Monoclonal antibodies, such as ofatumumab, may interfere with
      the ability of tumor cells to grow and spread. Giving lenalidomide and ofatumumab may work
      better in treating participants with chronic lymphocytic leukemia or small lymphocytic
      lymphoma
    

Eligibility criteria:

        Inclusion Criteria:

          -  Understand and voluntarily sign an informed consent

             National Cancer Institute (NCI)-sponsored working group 1) weight loss of > 10% in
             prior 6 months, 2) extreme fatigue, 3) fever or night sweats without evidence of
             infection, 4) worsening anemia or thrombocytopenia, 5) progressive lymphocytosis with
             a rapid lymphocyte doubling time, 6) marked hypogammaglobulinemia or paraproteinemia,
             7) lymphadenopathy > 5 cm in diameter

             status of 0-2

          -  Creatinine clearance > 30 ml/min (calculated by 24 hours urine collection) or a
             glomerular filtration rate (GFR) > 30 ml/min estimated using the Cockcroft-Gault
             equation

          -  Total bilirubin less or equal to 2 mg/dl

          -  Alanine aminotransferase (ALT) less or equal to two times the upper limit of normal

             basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix
             or breast. Patients with malignancies with indolent behavior such as prostate cancer
             treated with radiation or surgery can be enrolled in the study as long as they have a
             reasonable expectation to have been cured with the treatment modality received

          -  Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy
             test with a sensitivity of at least 50 mIU/mL within 10-14 days prior to starting
             lenalidomide and again within 24 hours prior to prescribing lenalidomide
             (prescriptions must be filled within 7 days) and prior to first ofatumumab
             administration and must either commit to continued abstinence from heterosexual
             intercourse or begin two acceptable methods of birth control, one highly effective
             method and one additional effective method at the same time, at least 28 days before
             she starts taking lenalidomide and continue it for 6 months after therapy has been
             completed. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a
             latex condom during sexual contact with a FCBP even if they have had a successful
             vasectomy. All study participants must be registered into the mandatory RevAssist
             program, and be willing and able to comply with the requirements of RevAssist

             performed and if positive the subject will be excluded
