Molecular response to treatment: Kinetics of response: MR2, MMR, MR4.0, MR4.5, undetectable MR4.5 for all patients.

MR2, MR4, MR4.5 are defined as the transcript ratio of BCR-ABL1/ABL1 being 1% or less, 0.01% or less and 0.0032% or less respectively

Kinetics of response: BCR::ABL1 on the International Scale (IS) for all patients

Kinetics of response: Time to MMR for patients not in MMR at treatment initiation

Molecular response to treatment: Duration of MMR for patients not in MMR at treatment initiation

EFS: time from index date to occurrence of one the events listed among variables:

• lack of efficacy, i.e., BRC::ABL1>1% or loss of CCyR if assessed
• disease progression (CML-AP/BP, CML death)
• death from any cause
• definitive treatment discontinuation due to any reason

PFS: time from index date to occurrence of one of the progression markers listed among variables:

• disease progression (CML-AP/BP, CML death),
• death from any cause,
• definitive treatment discontinuation due to any reason

The EORTC QLQ-C30 contains 30 questions assessed by the participant. There are 9 multiple-item scales: 5 scales that assess aspects of functioning (physical, role functioning, cognitive, emotional, and social); 3 symptom scales (Fatigue, Pain, and Nausea and Vomiting); and a global health status/Quality of Life (QOL) scale. There are 5 single-item measures assessing additional symptoms (i.e., dyspnea, loss of appetite, insomnia, constipation, and diarrhea) and a single item concerning perceived financial impact of the disease. All but two questions have 4-point scales ranging from "Not at all" to "Very much." The two questions concerning global health status/ QOL have 7 point scales with ratings ranging from "Very poor" to "Excellent." For each of the 14 domains, final scores are transformed such that they range from 0-100, where higher scores indicate improvement.

The EORTC QLQ-CML24 was designed to supplement the QLQ-C30 - the QLQ-CML24 is not a stand-alone instrument but is to be used in conjunction with the QLQ-C30.

The EORTC QLQ-CML 24 is composed of four multi-item scales and two single-item scales. The module consists of 24 items assessing symptoms burden (13 items), impact on worry/mood (4 items), impact on daily life (3 items), satisfaction with care and information (2 items) body image problems (1 item) and satisfaction with social life (1 item). The items were measured on four levels: 1=not at all, 2=a little, 3=quite a bit, 4=very much. For each domain, scores were averaged and transformed to 0 to 100. A higher score in satisfaction with social life domain indicates a higher level of satisfaction. A positive change from baseline indicates increasing satisfaction.
