Outcome Measures
Primary Outcomes (2)
Number of Participants With a Confirmed Response [Complete Response (CR) and Partial Response (PR)] on 2 Consecutive Evaluations at Least 4 Weeks Apart
National Cancer Institute working group criteria (NCIWG) was used to assess response. * CR: no lymphadenopathy, hepatomegaly, splenomegaly or constitutional symptoms; normal complete blood count; confirmed by bone marrow (BM) aspirate \& biopsy * PR: 50% decrease in peripheral blood lymphocytes, lymphadenopathy, liver/spleen size, presence/absence of constitutional symptoms; plus ≥1 of the following: ≥1500/μL polymorphonuclear leukocytes, \>100000/μL platelets, \>11.0 g/dL hemoglobin or 50% improvement for these parameters without transfusions
6 months
Number of Participants With Biological Response (Bio-R) on 2 Consecutive Evaluations at Least 4 Weeks Apart
Bio-R: A reduction in the absolute lymphocyte count (ALC) of more than 20% from the pretreatment level for at least 2 months or a \>= 30% reduction in all palpable lymphadenopathy without meeting the NCIWG criteria for PR was required
6 months
