Time to MCyR is defined as the time from the first dosing date until day criteria were first met for CCyR or PCyR, whichever occurred first.

Major Cytogenetic Response (MCyR) is defined as Complete Cytogenetic Response (CCyR: 0% Ph-chromosome-positive cells in metaphase in BM) or Partial Cytogenetic Response (PCyR: 1-35% Ph-chromosome-positive cells in metaphase in BM).

The duration of time from when the first day all criteria are met for CCyR or PCyR until the date of progression or death. Participants who neither progress nor die will be censored on the date of their last cytogenetic assessment. The duration of MCyR will be estimated via the Kaplan-Meier product-limit method.

Progression-free survival is defined as the time from first dosing date until the time progressive disease (PD) is first documented. Participants who die without a reported prior progression will be considered to have progressed on the date of their death. Participants who do not progress nor die will be censored on the date of their last hematologic or cytogenetic assessment, whichever comes last. PFS will be analyzed via the Kaplan-Meier product-limit method.

Participants were considered as having PD if they: achieved a hematologic response but subsequently no longer meet the criteria consistently on all assessment over a consecutive 2-week period after starting maximum dose; had no decrease from their baseline percent blasts in PB or BM on all assessments over a 4-week period, or had an increase by at least 50% in PB blast count (absolute) over a 2-week period after starting their maximum (individually-tolerated) dose.
