Primary Outcome Measures:
  • Overall response rate (ORR) [ Time Frame: any time point during the study up to 18 months ]
    ORR by the 2008 International Workshop on CLL (IWCLL) criteria

  • Cysteine 481 mutant clone [ Time Frame: any time point during the study ]
    The primary endpoint for Cohort 7 is the elimination of the cysteine 481 mutant clone


Secondary Outcome Measures:
  • Safety [ Time Frame: any time point during the study up to 18 months ]
    The incidence and severity of adverse events, and changes from baseline in laboratory parameters, vital signs, and physical examination will be determined.

  • ORR [ Time Frame: any time point during the study up to 18 months ]
    ORR by 1996 NCI Working Group Criteria

  • Progression-free survival (PFS) [ Time Frame: any time point during the study up to 18 months ]
  • Overall survival (OS) [ Time Frame: any time point during the study up to 18 months ]
  • Duration of response (DOR) [ Time Frame: any time point during the study up to 18 months ]
  • Resolution of disease-related symptoms [ Time Frame: Any time point during the study up to 18 months ]

Estimated Enrollment: 123
Study Start Date: September 2012
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: June 2018 (Final data collection date for primary outcome measure)
