What was measured

PFS was defined as time from randomization to progression or death. Progression is characterized by any of the following: * ≥ 50% increase from nadir since start of treatment (tx) in the sum of the products of ≥ 2 lymph nodes on 2 consecutive exams 2 weeks apart * ≥ 50% increase from nadir since start of tx in the size of liver and/or spleen * ≥ 50% increase in the absolute number of circulating lymphocytes not due to tumor flare reaction. The absolute lymphocyte count must be ≥ 5x10\^9/L to qualify as progression. * Transformation to a more aggressive histology. For patients with a complete response or nodular partial response, progression is defined as recurrence of circulating leukemia cell clone in the peripheral blood and an absolute lymphocyte count \> 5x10\^9/L and/or recurrence of palpable lymphadenopathy \>1.5 cm by physical exam. MRD status was evaluated at 2 years and samples with \<=20 monotypic events or an MRD level of \<10\^-4 were classified as undetectable MRD.
