A study evaluating venetoclax (ABT-199) in subjects with Chronic Lymphocytic Leukemia (CLL) whose cancer has come back or who had no response to previous cancer treatments including subjects who may be missing part of their chromosome 17 identified as 17p deletion, or TP53 gene mutation; or subjects who previously received treatment with B-cell receptor inhibitors.

- Primary Outcome Measures
Name Time Method Main Objective: The primary objective of this study to evaluate the efficacy of venetoclax monotherapy in subjects with relapsed or refractory chronic lymphocytic leukemia (CLL). ;Secondary Objective: The secondary objectives are to evaluate other efficacy parameters including the overall response rate (ORR), duration of overall response (DoR), time to progression (TTP), progression-free survival (PFS), overall survival (OS), Complete Remission rate in BCRi treated subjects.;Primary end point(s): The primary efficacy endpoint will be measured by complete remission rate (CR+CRi) of the subjects who have not been previously treated with BCRi therapy as assessed by the investigator.;Timepoint(s) of evaluation of this end point: The date the last enrolled subject has completed their Week 48 disease assessment, or after all enrolled subjects have discontinued venetoclax, whichever is earlier, will be defined as the data cutoff date for the efficacy analyses.
- Secondary Outcome Measures
Name Time Method Secondary end point(s): Key secondary efficacy endpoints: <br>Overall response rate, duration of response, time to progression, progression-free survival, overall survival, complete remission rate in B-Cell receptor inhibitor treated subjects.;Timepoint(s) of evaluation of this end point: The date the last enrolled subjects has completed their Week 48 disease assessment, or after all enrolled subjects have discontinued venetoclax, whichever is earlier, will be defined as the data cutoff date for the efficacy analyses.
