Timeframe: From study initiation to study closure, including up to 6 years of study follow-up

Duration of Response (DOR) (Complete Response [CR], CCR, Nodular Partial Response [nPR], Partial Response [PR], and PRL)

The Kaplan-Meier method will be used to estimate median DOR. DOR is the time from first objective status to progression or death. CR requires all of the following: absence of lymphadenopathy > 1.5 cm on physical exam/CT scan, no hepatomegaly/splenomegaly on physical exam, no clonal B-cells in the blood, Normal CBC, bone marrow aspirate & biopsy must be normocellular for age. PR requires >= 50% decrease in peripheral lymphocyte count from pre-treatment value, >= 50% reduction in lymphadenopathy, and/or ≥ 50% reduction in splenomegaly/hepatomegaly. CR with exception of having bone marrow lymphoid CLL nodules will be considered a nodular PR (nPR). CR with exception of not having a bone marrow biopsy performed will be considered a clinical CR (CCR). PR with the exception of having less than a 50% reduction in peripheral lymphocyte count will be considered a PR except persistent lymphocytosis (PRL). (NCT01886872)
