  Purpose

This single arm study will assess the efficacy and safety of MabThera in combina tion with fludarabine and cyclophosphamide, followed by MabThera maintenance the rapy, as first line treatment of patients with chronic lymphocytic leukemia. Pat ients will receive 6 cycles of treatment with MabThera (375mg/m2 i.v. on day 1 o f cycle 1, and 500mg/m2 i.v. on day 1 of cycles 2-6), fludarabine (25mg/m2 on da ys 1-3) and cyclophosphamide (250mg/m2 on days 1-3). Patients with a partial or complete response will receive maintenance treatment with MabThera (375mg/m2 i.v every 2 months). The anticipated time on study treatment is 2+ years, and the target sample size is <100 individuals.
