Overall Response Rate [ Time Frame: Up to 42 months ]
Overall response rate was defined as the percentage of participants with a complete response (CR) or a partial response (PR) according to National Cancer Institute - Working Group [NCI-WG] guidelines. CR: no clonal B lymphocytes in peripheral blood, no significant lymphadenopathy, liver and spleen normal size, no disease symptoms, blood counts: absolute neutrophil count (ANC) >1,500/microliter (mcL), platelets > 100,000/mcL, hemoglobin > 11.0 grams/deciliter (g/dL), normocellular bone marrow. PR: >/= 50% decrease in clonal B lymphocyte count, >/= 50% reduction in lymphadenopathy, >/= 50% reduction of liver or spleen enlargement and ANC >1,500/mcL, platelets > 100,000/mcL, hemoglobin > 11.0 g/dL OR >/= 50% increase in ANC, platelets or hemoglobin.

  • Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to 53 months ]
    An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. Preexisting conditions which worsen during a study are also considered as adverse events. An SAE is any experience that suggests a significant hazard, contraindication, side effect, or precaution, and fulfills any of the following criteria: fatal (resulted in death), life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was medically significant or required intervention to prevent any of the other outcomes listed here.
  • Percentage of Participants With Neutropenic Fever, Infection, >/= Grade 3 Drug-Related Neutropenia, >/= Grade 3 Drug-Related Thrombocytopenia, Hospitalizations [ Time Frame: Up to 53 months ]
  • Hospitalization Days [ Time Frame: Up to 53 months ]
  • Progression-free Survival (PFS) [ Time Frame: Up to 53 months ]
    PFS was defined as the interval from the first study drug treatment day to the first sign of disease progression according to NCI-WG guidelines. Progressive disease (PD): Any new lesion, any disease symptoms, >/=50% increase in lymphadenopathy, splenomegaly, hepatomegaly, >/= 50% increase in the number of circulating clonal B lymphocytes, decrease of hemoglobin levels by > 2.0 g/dL, >/= 50% decrease of platelet counts, increase of lymphocytes in bone marrow to more than 30% from normal.
  • Quality of Life (QoL): Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) Questionnaire [ Time Frame: [Visit 1 (Screening, Week 0), at Visits 11 (Week 45) and 14 (Week 80) and at the end of the study (Month 42)] ]
    The FACIT-F questionnaire consists of 13 questions with a total score range of 0 to 52 with 0 indicating a better outcome and 52 indicating a worse outcome.
  • Safety: Incidence of adverse events (especially neutropenic fever, infection rate, number of hospitalization days, thrombocytopenia >/= grade 3, neutropenia >/= grade 3)) [ Time Frame: 5 years ]
  • Progression-free survival (according to NCI-WG guidelines) [ Time Frame: up to 36 months ]
  • Time to next treatment [ Time Frame: up to 36 months ]
  • Quality of life: Functional Assessment of Chronic Illness Therapy (FACIT) questionnaire [ Time Frame: up to 36 months ]

A Study of MabThera/Rituxan (Rituximab) in Combination With Fludarabine And Cyclophosphamide as Primary Therapy in Elderly Patients With Chronic Lymphocytic Leukemia
A Phase II, Multicenter, Single Arm Study to Determine the Efficacy and Safety of Low Dose Fludarabine and Cyclophosphamide Combined With Standard Dose Rituximab as Primary Therapy in Elderly Untreated Patients (>/=65 Years Old) With Chronic Lymphocytic Leukemia
This single arm, open-label study will assess the safety and efficacy of low dose fludarabine and cyclophosphamide in combination with standard dose MabThera/Rituxan (rituximab) as primary therapy in elderly patients (>/= 65 years) with chronic lymphocytic leukemia. Patients will receive six 28-day cycles of treatment with Mabthera/Rituxan (375 mg/m2 intravenously [iv] Day 0 of cycle 1, 500 mg/m2 iv Day 1 of cycles 2-6), fludarabine (12.5 mg/m2/d iv Days 1-3, cycles 1-6) and cyclophosphamide (150 mg/m2/d iv Days 1-3, cycles 1-6). Anticipated time on study treatment is 6 months, with a 30-month follow-up period.

Phase 2
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Lymphocytic Leukemia, Chronic
  • Drug: Cyclophosphamide
    150 milligrams per square meter (mg/m^2) intravenously (IV) on Days 1-3 of each 28-day cycle for 6 cycles
  • Drug: Fludarabine
    12.5 mg/m^2 IV on Days 1-3 of every 28-day cycle for 6 cycles
  • Drug: Rituximab
    375 mg/m^2 IV Day 0 of Cycle 1, 500 mg/m^2 IV Day 1 of Cycles 2-6. Each cycle was 28 days.
    Other Name: MabThera/Rituxan
Experimental: Rituximab plus Fludarabine and Cyclophosphamide
Elderly participants with chronic lymphocytic leukemia (CLL) will receive combination treatment with low-dose fludarabine and cyclophosphamide combined with standard-dose of rituximab for 6 months. Treatment is followed by a follow up period of 36 months.
