2016年3月30日 更新者：Hoffmann-La Roche
A Multicenter, Single-Arm, Phase II Study to Evaluate the Efficacy and Safety of Rituximab Plus Fludarabine and Cyclophosphamide (FCR) as First-Line Treatment in Patients With B-Cell Chronic Lymphocytic Leukemia (CLL)
This study will evaluate the efficacy and safety of rituximab in combination with chemotherapy (fludarabine and cyclophosphamide) in participants with B-cell CLL.

实验性的：Rituximab + Fludarabine + Cyclophosphamide
Participants will receive rituximab (375 milligrams per meter-squared [mg/m^2] intravenously [IV]) on Cycle 1 Day 1, followed by fludarabine (25 mg/m^2 once daily IV) and cyclophosphamide (250 mg/m^2 once daily IV) for Days 2 to 4 of Cycle 1. Then rituximab (500 mg/m^2 IV) will be administered on Day 1 of Cycles 2 to 6, followed by IV fludarabine (25 mg/m^2 once daily IV) and cyclophosphamide (250 mg/m^2 once daily IV) on Days 1 to 3 of Cycles 2 to 6.
Each cycle will be 28 days or 4 weeks in length, and the overall duration of treatment will be approximately 6 months.

Cyclophosphamide will be administered IV at 250 mg/m^2/day on Day 2-4 of Cycle 1 and then on Day 1-3 of Cycles 2 to 6.
Each cycle will be 28 days or 4 weeks in length.
Fludarabine will be administered IV at 25 mg/m^2/day on Day 2-4 of Cycle 1 and then on Day 1-3 of Cycles 2 to 6.
Each cycle will be 28 days or 4 weeks in length.
Rituximab will be administered IV at 375 mg/m^2 on Day 1 of Cycle 1 and then at 500 mg/m^2 on Day 1 of Cycles 2 to 6.
Each cycle will be 28 days or 4 weeks in length.

措施说明 |
大体时间 |
|---|---|---|

Percentage of Participants With Death or Disease Progression
大体时间：Up to 5 years (from Baseline until disease progression or death, whichever occurred first)
|
Treatment response was monitored throughout the study and assessed using standardized criteria.
Disease progression was defined as the occurrence of at least one of the following: greater than or equal to (≥) 50 percent (%) increase in the longest diameter of at least two enlarged lymph nodes, increase in spleen and/or liver size by at least 2 centimeters (cm) from Baseline as determined by measurement below the costal margin, or ≥50% increase in the number of circulating lymphocytes.
The percentage of participants with death or documented disease progression at any time during the study was calculated.
|
Up to 5 years (from Baseline until disease progression or death, whichever occurred first)
|
|
Progression-Free Survival (PFS)
大体时间：Up to 5 years (from Baseline until disease progression or death, whichever occurred first)
|
Treatment response was monitored throughout the study and assessed using standardized criteria.
Disease progression was defined as the occurrence of at least one of the following: ≥50% increase in the longest diameter of at least two enlarged lymph nodes, increase in spleen and/or liver size by at least 2 cm from Baseline as determined by measurement below the costal margin, or ≥50% increase in the number of circulating lymphocytes.
PFS was defined as the time from study inclusion until first event of disease progression or death and was estimated using Kaplan-Meier analysis.
|
Up to 5 years (from Baseline until disease progression or death, whichever occurred first)
|
|
Percentage of Participants Who Died
大体时间：Up to 5 years (from Baseline until death)
|
Participants were followed for survival throughout the study.
The percentage of participants who died of any cause during the study was calculated.
|
Up to 5 years (from Baseline until death)
|
|
Overall Survival (OS)
大体时间：Up to 5 years (from Baseline until death)
|
Participants were followed for survival throughout the study.
OS was defined as the time from study inclusion until death from any cause and was estimated using Kaplan-Meier analysis
|
Up to 5 years (from Baseline until death)
|
|
Percentage of Participants With Complete Response (CR), Nodular Partial Response (nPR), or Partial Response (PR)
大体时间：Up to 4 years (assessed every 3 months during 6-month treatment period, every 2 months during 6-month safety follow-up, then every 3 months during 3-year safety follow-up)
|
Treatment response was monitored throughout the study and assessed using standardized criteria.
CR was defined as hemoglobin ≥11 grams per deciliter (g/dL), lymphocytes less than (<) 4000 cells per cubic millimeter (cells/mm^3), neutrophils greater than (>) 1500 cells/mm^3, platelets >100,000 cells/mm^3, bone marrow (BM) biopsy with <30% lymphocytes with no lymphocytic infiltrates, no evidence of lymphoid nodules on physical exam, and performance status of 0. PR was defined as >50% decrease in size of enlarged lymph nodes, hepatomegaly, and splenomegaly, with peripheral counts meeting the same criteria as CR or ≥50% improvement from pre-treatment values.
Participants with lymphoid nodules on BM biopsy who otherwise met CR criteria were considered nPR.
The percentage of participants with each level of best overall response was calculated.
|
Up to 4 years (assessed every 3 months during 6-month treatment period, every 2 months during 6-month safety follow-up, then every 3 months during 3-year safety follow-up)
