This randomized, parallel-group, multi-center study will compare the pharmacokin etics and safety of subcutaneous administration of MabThera (rituximab) versus i ntravenous MabThera in combination with chemotherapy in previously untreated pat ients with chronic lymphocytic leukemia (CLL). The study consists of 2 parts. In part 1, patients who have previously received 4 cycles of intravenous MabThera will receive in Cycle 5 intravenous MabThera and in Cycle 6 subcutaneous MabTher

a. In part 2, patients will be randomized to receive either 6 cycles of intraven ous MabThera, or 1 cycle of intravenous MabThera and 5 cycles of subcutaneous Ma bThera. Additionally, all patients will receive chemotherapy (fludarabine and cy clophosphamide) on days 1-3 of every cycle. The anticipated time on study drug i s 20 weeks.

Primary Outcome Measures:
  • Part 1: C(trough) levels of subcutaneous MabThera [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Part 2: Physician and nurse opinion on the convenience of subcutaneous MabThera [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
  • Part 1 and 2: Pharmacokinetics (Area under curve for subcutaneous and intravenous MabThera) [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
  • Part 1 and 2: Immunogenicity of subcutaneous MabThera [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
  • Part 1 and 2: Change of blood B-cell levels [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
  • Part 1: Injection-related reactions during the subcutaneous cycle [ Time Frame: Week 6 ] [ Designated as safety issue: No ]
  • Part 1: Patients and nurse preference regarding subcutaneous and intravenous administration [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Part 2: Safety (nature and incidence of adverse events) [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
  • Part 2: Physician and nurse opinion on time savings with subcutaneous MabThera [ Time Frame: 20 weeks ] [ Designated as safety issue: No ]
