This single arm study will evaluate the bone marrow response, safety and tolerability of six months treatment with Avastin monotherapy in patients with chronic lymphocytic leukemia. Patients will receive 8 cycles (21 days duration) of Avastin monotherapy (15mg/kg) with 6 months of follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.
