Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	ORR	overall remission rate, including complete remission without minimum residual disease (CRMRD-), complete remission (CR), complete remission with incomplete hematologic recovery (CRi), complete remission without platelet recovery (CRp), partial remission (PR).	up to 24 months
Primary	composite complete remission (CRc) rate	CRc rate is defined as the rate of all complete and incomplete remission (CRMRD-+CR+CRp+CRi).	up to 24 months.
Secondary	RFS	relapse-free survival, for patients achieving a complete remission, defined as the interval from the date of first documentation of a leukemia free state to date of recurrence, treatment failure, death due to any cause or last contact of the end-of-study follow up, which ever occurs first.	up to 24 months
Secondary	EFS	event-free survival, EFS is defined as the time from the date of enrollment until the date of documented relapse from CR, CRp or CRi, treatment failure, death from any cause or last contact of the end-of-study follow-up, whichever occurs first.	up to 24 months
Secondary	OS	overall survival, OS is defined as time from the date of enrollment until the date of death from any cause. For a subject who is not known to have died buy the end-of-study follow-up, OS is censored at the date of last contact.	up to 24 months
Secondary	duration of CR remission	DOR-CR is defined as the time from the date of first CR, CRp, CRi until the date of documented relapse.	up to 24 months
Secondary	Incidence of Treatment-Emergent Adverse Events (Safety and tolerability)	safety and tolerability of investigational product assessed as the number of participants experience adverse events (AEs, CTCAE 5.0) or abnormalities in vital signs, laboratory tests, or electrocardiograms.	up to 24 months
Secondary	Cmax,ss	Peak plasma concentration at steady state	at the end of Cycle 1 (each cycle is 28 days)
Secondary	Cmin,ss	Minimum plasma concentration at steady state	at the end of Cycle 1 (each cycle is 28 days)
Secondary	Cav,ss	The average steady-state plasma concentration	at the end of Cycle 1 (each cycle is 28 days)
