E.5 End points |
E.5.1 | 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. |
|
E.5.1.1 | 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. |
|
E.5.2 | Secondary end point(s) |
Key secondary efficacy endpoints:
Overall response rate, duration of response, time to progression, progression-free survival, overall survival, complete remission rate in B-Cell receptor inhibitor treated subjects. |
|
E.5.2.1 | 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. |
