Current Primary Outcome Measures  ICMJE
 (submitted: January 27, 2022)
Progression Free Survival (PFS) by Independent Review Committee (IRC) Assessment [ Time Frame: Randomization to Disease Progression, Death, or Censoring. Assessed for up to 5 years at the time of analysis. ]
The time from date of randomization to the date of first IRC-assessed disease progression or death due to any cause. Progression by IRC is defined per International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria as lymphocyte count >/= 50% from baseline; >/= 50% increase in lymph nodes, liver or spleen; >/= 50% decrease in platelets from baseline or decrease in hemoglobin > 2 g/dL from baseline and related to CLL.
Original Primary Outcome Measures  ICMJE

Progression-free survival in Arm A compared to Arm B [ Time Frame: 36 months ]
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: January 27, 2022)
Number of Patients With Atrial Fibrillation [ Time Frame: Date of first dose until 30 days after the last dose of study drug or the start of new anticancer therapy (whichever comes first). Median follow-up was 41 months. ]
Includes MedDRA preferred terms 'atrial fibrillation' and 'atrial flutter'.
Original Secondary Outcome Measures  ICMJE
 (submitted: June 22, 2015)
  • Incidence of treatment-emergent Grade ≥ 3 infections in Arm A versus Arm B [ Time Frame: 36 months ]
  • Incidence of Richter's transformation in Arm A versus Arm B [ Time Frame: 36 months ]
  • Incidence of Atrial fibrillation in Arm A versus Arm B [ Time Frame: 36 months ]
  • Overall survival in Arm A versus Arm B [ Time Frame: 36 months ]
