Title: Phase II Trial of Pentostatin, Cyclophosphamide, and Ofatumumab for Previously Untreated Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL)
Brief Summary: This phase II trial studies how well giving ofatumumab together with pentostatin and cyclophosphamide works in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma. Monoclonal antibodies, such as ofatumumab, can block the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as pentostatin and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ofatumumab together with pentostatin and cyclophosphamide may be a better way to block cancer growth.

* Patients must be previously untreated and meet at least one of the following indications for chemotherapy:
