What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Responders and Number of Non-responders Defined by International Working Group Response Criteria
Time Frame: 2 Years
Number of responders is defined as the number of patients in the analysis population who have complete response (CR), partial response (PR), or hematologic improvement (HI) per International Working Group Response Criteria during the course of the study. Confirmation of CR or PR will require a second assessment performed 4 weeks or more after the initial assessment. Confirmation of HI will require a second assessment performed 8 weeks or more after the initial assessment. Number of non-responders is defined as the number of patients who did not achieve CR, PR or HI in the study.
2 Years
Safety and Tolerability as Assessed by the Number of Participants With Adverse Events.
Time Frame: Every 21 days while on therapy and at 30 days after the last dose of study therapy
Every 21 days while on therapy and at 30 days after the last dose of study therapy
