Provision of signed informed consent for secondary use of data, or an ethics committee-approved waiver of consent, where applicable (including for deceased patients or where data were previously collected within the EHR system)
Patients who do not meet the eligibility criteria specified above
Patients with insufficient medical record documentation to determine asciminib exposure or key study outcomes
