Limitations and caveats
After notification by the US Food and Drug Administration on 12Jul2013, Celgene agreed to stop lenalidomide due to an imbalance in the number of deaths on the lenalidomide arm versus the chlorambucil arm; no causality for the imbalance was identified

ListOutcomeTime frameDescription
PrimaryKaplan-Meier Estimate of Progression Free Survival (PFS)From first dose of study drug to date of data cut-off of 18 Feb 2013; up to approximately 39 months
Progression-free survival was defined as the time from randomization to the first documented progression confirmed per investigator's assessment or death due to any cause on study, whichever occurred first. The progression date was assigned to the earliest time when any progression was observed without prior missing assessments. If withdrawal of consent or lost to follow-up occurred before documented progression or death, then these observations were censored at the date when the last complete tumor assessments determined a lack of progression
PrimaryKaplan-Meier Estimate of Progression Free Survival (PFS) With a Later Cut-off Date of 14 March 2014From randomization to data cut off date of 31 March 2014; median follow up time for all participants was 12.6 months
Progression-free survival was defined as the time from randomization to the first documented progression confirmed per investigator's assessment or death due to any cause on study, whichever occurred first. Progressive disease included lymphadenopathy, an appearance of any new lesion such as enlarged lymph nodes (\> 1.5 cm), splenomegaly, hepatomegaly or other organ infiltrates, an increase by 50% or more in greatest determined diameter of any previous site or an increase by 50% or more in the sum of the product of diameters of multiple nodes. The progression date was assigned to the earliest time when any progression was observed without prior missing assessments. If withdrawal of consent or lost to follow-up occurred before documented progression or death, then these observations were censored at the date when the last complete tumor assessments determined a lack of progression.
SecondaryNumber of Participants With Adverse Events (AEs)From randomization up to data cut-off of 18 Feb 2013; Up to approximately 39 months; maximum duration of exposure for Lenalidomide was 1086 days and 406 days for Chlorambucil
AEs = any noxious, unintended, or untoward medical occurrence that may appear or worsen during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, regardless of cause. Serious AE (SAE) = any AE which results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; constitutes an important medical event. The severity of AEs were graded based upon the participants symptoms according to the Common Terminology Criteria for Adverse Events (CTCAE, Version 4.0); AEs were evaluated for severity according to the following scale: Grade 1 = Mild - transient or mild discomfort; no medical intervention required; Grade 2 = Moderate - mild to moderate limitation in activity; Grade 3 = Severe; Grade 4 = Life threatening; Grade 5 = Death
SecondaryNumber of Participants With Adverse Events With a Later Cut-off Date of 31 March 2014From randomization to the data cut-off date of 31 March 2014; Up to 53 months; maximum duration of exposure for Lenalidomide was 1140 days and 406 days for Chlorambucil
AEs = any noxious, unintended, or untoward medical occurrence that may appear or worsen during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, regardless of cause.

SecondaryPercentage of Participants With the Best Overall Response Based on the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) GuidelinesUp to data cut-off date of 18 Feb 2013; approximately 39 months
A best overall response rate is a CR, CRi, nPR or PR and is defined as: Complete Remission (CR): * No lymphadenopathy * No hepatomegaly or splenomegaly * Absence of constitutional symptoms * Polymorphonuclear leukocytes ≥ 1500/ul * No circulating clonal B-lymphocytes * Platelets \> 100,000/ul * Hemoglobin \> 11.0 g/dl * Normocellular \<30% lymphocytes, no B-lymphoid nodules; Incomplete Clinical Response (CRi): • CR without bone marrow biopsy confirmation. Nodular Partial Response (nPR): • CR with the presence of residual clonal nodules. Partial Response (PR) requires: * ≥ 50% decrease in peripheral blood lymphocyte count * ≥ 50% reduction in lymphadenopathy * ≥ 50% reduction in size of liver and/or spleen * 1 or more of the following: * Polymorphonuclear leukocytes ≥ 1500/ul * Platelets \>100,000/ul

SecondaryKaplan-Meier Estimate for Duration of ResponseUp to data cut-off of 18 Feb 2013; up to approximately 39 months
Duration of response was defined as the time from first nPR, PR, CRi, or CR to PD. Duration of response was censored at the last date that the patient was known to be progression-free for: 1) participants who had not progressed at the time of analysis; 2) participants who had withdrawn consent or were lost to follow-up prior to documentation of progression
SecondaryKaplan-Meier Estimate for Duration of Response With a Later Cut-off Date of 31 March 2014Up to data cut-off of 31 March 2014; up to approximately 53 months
