ListOutcomeTime frameDescription
PrimaryPercentage of Participants With Major Molecular Response (MMR) at Week 48 - Ascimimib vs. Investigator Selected TKIAt 48 weeks
Molecular response is assessed using BCR-ABL1 transcript levels measured by realtime quantitative polymerase chain reaction. MMR is defined as a ratio BCR-ABL/ABL ≤0.1% on the international scale (ie, at least 3 log reduction from a standardized baseline value).
PrimaryPercentage of Participants With Major Molecular Response (MMR) at Week 48 - Asciminib (Imatinib Stratum) vs Investigator Selected TKI (Imatinib Stratum)At 48 weeks
Molecular response is assessed using BCR-ABL1 transcript levels measured by realtime quantitative polymerase chain reaction. MMR is defined as a ratio BCR-ABL1/ABL ≤0.1% on the international scale (ie, at least 3 log reduction from a standardized baseline value).
SecondaryMajor Molecular Response at Week 96at 96 weeks (96 weeks after last patient first dose)
Molecular response is assessed using BCR-ABL transcript levels measured by realtime quantitative polymerase chain reaction. MMR is defined as a ratio BCR-ABL/ABL ≤0.1% on the international scale (ie, at least 3 log reduction from a standardized baseline value).
SecondaryTime to Discontinuation of Study Treatment Due to Adverse Events (TTDAE)96 weeks after last patient first dose
TTDAE is defined as the time from the date of first dose of study treatment to the date of discontinuation of study treatment due to Adverse Event (AE). For patients ongoing without study treatment discontinuation, on or prior to the analysis cut-off date, the time will be censored at the at the analysis cut-off date.
SecondaryMajor Molecular Response at Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Molecular response is assessed using BCR-ABL transcript levels measured by realtime quantitative polymerase chain reaction. MMR is defined as a ratio BCR-ABL/ABL ≤0.1% on the international scale (ie, at least 3 log reduction from a standardized baseline value).

SecondaryMR4.0 at Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Molecular response is assessed using BCR-ABL transcript levels measured by realtime quantitative polymerase chain reaction. MR4.0 is defined as a ratio BCR-ABL/ABL ≤0.01% on the international scale (ie, at least 4 log reduction from a standardized baseline value).
SecondaryMR4.5 at All Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Molecular response is assessed using BCR-ABL transcript levels measured by realtime quantitative polymerase chain reaction. MR4.5 is defined as a ratio BCR-ABL/ABL ≤0.0032% on the international scale (ie, at least 4.5 log reduction from a standardized baseline value).
SecondaryMR4.0 by Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Molecular response is assessed using BCR-ABL transcript levels measured by realtime quantitative polymerase chain reaction. MR4.0 is defined as a ratio BCR-ABL/ABL ≤0.01% on the international scale (ie, at least 4 log reduction from a standardized baseline value).

SecondaryComplete Hematological Response (CHR) at All Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Hematologic response will be assessed by CBC and physical examination at each visit. Complete Hematological Response (CHR) will be defined as all of the following present for ≥ 4 weeks: white blood cell(s) (WBC) count \< 10 x 10\^9/L PLT count \< 450 x 10\^9/L Basophils \< 5% No blasts and promyelocytes in peripheral blood Myelocytes + metamyelocytes \< 5% in peripheral blood No evidence of extramedullary disease, including spleen and liver
SecondaryComplete Hematological Response (CHR) by All Scheduled Data Collection Time PointsPlanned total follow-up duration of 5 years
Hematologic response will be assessed by CBC and physical examination at each visit. Complete Hematological Response (CHR) will be defined as all of the following present for ≥ 4 weeks: white blood cell(s) (WBC) count \< 10 x 10\^9/L PLT count \< 450 x 10\^9/L Basophils \< 5% No blasts and promyelocytes in peripheral blood Myelocytes + metamyelocytes \< 5% in peripheral blood No evidence of extramedullary disease, including spleen and liver
SecondaryPercentage of Participants With Complete Cytogenic Response (CCyR) by Week 48 & Week 96By week 48 and by week 96 (48 weeks and 96 weeks after last patient first dose); data collection/analysis is ongoing for the 96 week time point, and the data will be reported later
The CCyR response status was to be based on bone marrow assessment. Bone marrow examination for cytogenetic assessment was to be performed locally by the Investigator at baseline for all participants. Thereafter, during the course of the study, cytogenetic assessment was not mandatory and only performed if clinically indicated.
SecondaryDuration of MMRPlanned total follow-up duration of 5 years
Duration of MMR is defined as the time between the date of the first documented achievement of MMR and the earliest date of loss of MMR, treatment failure, progression to Accelerated Phase/Blast Crisis, or CML-related death
SecondaryDuration of MR4.0Planned total follow-up duration of 5 years
Duration of MR4.0 is defined as the time between the date of the first documented achievement of MR4.0 and the earliest date of loss of MR4.0, treatment failure, progression to Accelerated Phase/Blast Crisis, or CML-related death
SecondaryDuration of MR4.5Planned total follow-up duration of 5 years
Duration of MR4.5 is defined as the time between the date of the first documented achievement of MR4.5 and the earliest date of loss of MR4.5, treatment failure, progression to Accelerated Phase/Blast Crisis, or CML-related death
SecondaryTime to First MMRPlanned total follow-up duration of 5 years
Time to first MMR is defined as the time from the date of randomization to the date of the first documented occurrence of MMR. Time will be censored at the last molecular assessment date while on treatment, or the End Of Treatment (whichever comes first) for patients who have not experienced MMR.

SecondaryTime to First MR4.5Planned total follow-up duration of 5 years
Time to first MR4.5 is defined as the time from the date of randomization to the date of the first documented occurrence of MR4.5. Time will be censored at the last molecular assessment date while on treatment, or the End Of Treatment (whichever comes first) for patients who have not experienced MR4.5.
