Summary:

      The main purpose of this study is to see if the combination of ofatumumab with high dose
      methylprednisolone followed by additional treatment with ofatumumab and lenalidomide can help
      people with relapsed or refractory CLL/SLL get rid of their CLL/SLL for a long period of
      time. Researchers also want to find out if the combination of ofatumumab with
      methylprednisolone followed by additional treatment with ofatumumab and lenalidomide is safe
      and tolerable.

             marrow (BM) lymphocytes ≥ 30%; Or previous confirmed diagnosis of CLL/SLL with less
             than 5000/μl or less than 30% lymphocytes in BM.
