Best response rate for participants with AML

Number and percentage of participants with CR, CRi, CRh, PR, MLFS, SD, No Response and Progressive Disease (PD).

Time frame: From the date of treatment initiation up to end of study (approximately 1.5 years)

Best response rate for participants with CMML

Number and percentage of participants with CR, CCR, PR, MR, CB and PD.

Time frame: From the date of treatment initiation up to end of study (approximately 1.5 years)

Overall Survival (OS)

OS is defined as the time from the date of the first dose of study drug until the date of death for any cause.

Time frame: From the date of treatment initiation until death or up to 1.5 years from patient's first dose, whichever comes first

Time to Response (TTR)

TTR is defined as the time from the first dose of study drug until the date of first response (CRc or PR).

Time frame: From the date of treatment initiation up to end of study (approximately 1.5 years)

Duration of Response (DoR)

Duration of response was defined as the time from the date of either first CRc or PR until the date of documented relapse of any type for participants who achieved CRc or PR.

Time frame: From the date of first response up to end of study (approximately 1.5 years)

Event-Free Survival (EFS)

For patients with diagnosis of AML the primary analysis measures the time from the date of treatment initiation to the date of first documentation of disease progression or hematologic relapse after CR/CRh/CRi, treatment failure or death from any cause, whichever comes first. For patients with CMML, EFS will be defined as the time from treatment start until disease progression, relapse after CR, CCR, PR, MR or CB, treatment failure, or death from any cause, whichever comes first.

Time frame: From the date of treatment initiation until death or up to 1.5 years from patient's first dose, whichever comes first

For patients with CMML diagnosis, RFS will be measured from the date of first achievement of CR, CCR, PR, MR or CB until the date of relapse or death from any cause.

Time frame: From the date of treatment initiation until death or up to 1.5 years from patient's first dose, whichever comes first

For AML and in Phase II only: Complete Remission (CR) Rate

Defined as the number of patients who achieve a CR as Best Response, divided by the number of participants in the analysis population.
