What was measured

Overall response rate was defined as the percentage of participants who achieved a best overall response of complete response or partial response. Complete response was defined as no lymphadenopathy, hepatomegaly, splenomegaly; normal complete blood count; confirmed by bone marrow aspirate \& biopsy. Partial response was defined as \>1 of the following criteria: a 50% decrease in peripheral blood lymphocytes, lymphadenopathy, liver size, spleen size; plus ≥ 1 of the following: ≥ 1500/μL absolute neutrophil count, \> 100000/μL platelets, \> 11.0 g/dL hemoglobin or 50% improvement for either of these parameters without transfusions or growth factors.

Analysis population: ITT Analysis Set: randomized participants with treatment group designated according to initial randomization.
