Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression-Free Survival (PFS) as Assessed Using Kaplan-Meier Estimate
Time Frame: From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
PFS was defined as the time from initiation of treatment with rituximab in combination with chemotherapy to disease progression or death due to any cause, whichever occurred first. 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. Participants without disease progression or death at the time of analysis were censored at the last date of tumor evaluation in terms of PFS.
From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
Percentage of Participants Without Progression or Death
Time Frame: From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
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.
From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Progression and Death
Time Frame: From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
Percentage of participants with an event (progression or death) was reported. 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.
From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
Percentage of Participants Who Received Each Treatment During the Course of Study
Time Frame: Baseline, Cycle 1, 2, 3, 4, 5, 6, 7, 8, last Cycle (Cycle 18) (each cycle=1 month)
The chemotherapeutic regimen administereted during the course of study were: Rituximab-Bendamustine (R-Benda), Rituximab-Fludarabine-Cyclophosphamide (R-FC), Rituximab-Clorambucil (R-Clb), R-Other and Rituximab mono.
Baseline, Cycle 1, 2, 3, 4, 5, 6, 7, 8, last Cycle (Cycle 18) (each cycle=1 month)
Mean Body Weight
Time Frame: Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Percentage of Participants With Eastern Cooperative Oncology Group (ECOG) Performance Status
Time Frame: Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
ECOG performance status was measured on a 4 point scale to assess participant's performance status. 0=Fully active, able to carry on all pre-disease activities without restriction; 1=Restricted in physically strenuous activity, ambulatory and able to carry out light or sedentary work; 2=Ambulatory (>50% of waking hours), capable of all self-care, unable to carry out any work activities; 3=Capable of only limited self-care, confined to bed/chair >50% of waking hours.
Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Percentage of Participants With Karnofsky Performance Status Index
Time Frame: Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Performance status was reflected by the Karnofsky index. Karnofsky performance status index ranges from 0-100% with higher scores indicating better functional status. An index between 90% and 100% corresponds to ECOG grade 0, index between 70% and 80% corresponds to ECOG grade 1, index between 50% and 60% corresponds to ECOG grade 2, index 40% corresponds to ECOG grade 3. ECOG grade 0=Fully active, able to carry on all pre-disease activities without restriction; grade 1=Restricted in physically strenuous activity, ambulatory and able to carry out light or sedentary work; grade 2=Ambulatory (>50% of waking hours), capable of all self-care, unable to carry out any work activities; grade 3=Capable of only limited self-care, confined to bed/chair >50% of waking hours.
Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Percentage of Participants With General Symptoms
Time Frame: Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)

B-symptoms included fever, night sweats, weight loss.
Baseline, last cycle (Cycle 18) (each cycle=1 month), last visit (follow-up) (24 months)
Percentage of Participants With Best Overall Response (BOR)
Time Frame: From initiation of treatment up to disease progression or death due to any cause, whichever occurred first (assessed up to 24 months)
Response to treatment was assessed as per clinical routine. BOR included complete response(CR or CR with incomplete hematopoietic regeneration),partial response(PR or nodular PR),stable disease(SD),progressive disease(PD). CR:hemoglobin>/=11 grams/deciliter(g/dL), lymphocytes<4000 cells/cubic millimeter(cells/mm^3), neutrophils>5000 cells/mm^3,platelets>100,000 cells/mm^3,bone marrow biopsy with <30% lymphocytes with no lymphocytic infiltrates, no evidence of lymphoid nodules on physical exam, performance status of 0. PR:>50% decrease in size of enlarged lymph nodes, hepatomegaly, splenomegaly, with peripheral counts meeting same criteria as CR or >/=50% improvement from pre-treatment values.PD:occurrence of at least one of following: >/=50% increase in longest diameter of at least 2 enlarged lymph nodes, increase in spleen and liver size by at least 2 cm from Baseline, or >/=50% increase in number of circulating lymphocytes. Participants without CR/PR or PD were considered having SD.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
