Observational Study of Asciminib Safety and Effectiveness in Adults with Philadelphia Chromosome-Positive Chronic Myeloid Leukemia in Chronic Phase in Germany Including Newly Diagnosed and Previously Treated Patients

What this Trial Is About

Researchers are evaluating the real-world effectiveness of asciminib in adult patients with Philadelphia chromosome-positive chronic myeloid leukemia in the chronic phase Ph CML-CP. This observational study compares patients who are newly diagnosed or previously treated with one ATP-competitive tyrosine kinase inhibitor TKI to those treated with other TKIs. The study aims to assess tolerability, safety, and molecular response outcomes in routine clinical care. Participants are grouped into cohorts based on their treatment those receiving asciminib, those newly diagnosed treated with imatinib, and those newly diagnosed treated with second-generation TKIs such as dasatinib, bosutinib, or nilotinib. Treatment decisions are made by physicians prior to enrollment, and treatment must not have started more than 14 days before joining the study. The study follows patients over time to document treatment patterns, dose changes, interruptions, and discontinuations. Participants will attend routine follow-up visits and complete patient-reported outcome questionnaires assessing medication adherence, quality of life, and work productivity at multiple time points up to 24 months. Researchers will measure major molecular response at 12 months as the primary outcome and evaluate various secondary molecular responses, reasons for treatment changes, and quality of life scores. The study duration extends through September 2030, allowing long-term observation of treatment effectiveness and safety.
