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.

Immune thrombocytopenia ITP is a rare blood disorder caused by an autoimmune condition that reduces platelet counts, increasing the risk of bleeding or prolonged bleeding. New treatments for ITP have emerged recently, but existing clinical studies are limited in their applicability to everyday patient care due to strict criteria. This registry aims to collect real-world clinical data and biospecimens from patients with various types of ITP to improve understanding of diagnosis, therapy, and patient outcomes in routine treatment. The registry includes patients diagnosed with primary or secondary ITP who consent to participate. Data collection occurs at defined points in the disease course either prospectively or retrospectively up to 12 months after diagnosis, provided continuous documentation is available. Biospecimens are collected and stored systematically to support research. Clinical information collected includes disease characteristics, treatment types, complications, quality of life, fatigue scores, and survival data over a follow-up period of up to 5 years. Participants provide clinical data and biosamples at enrollment, then again at 6 months and annually for up to 5 years. Assessments include platelet counts, bleeding and thromboembolic events, laboratory markers such as specific antibodies, and patient-reported outcomes like quality of life and fatigue. The study gathers epidemiological data on incidence, age, sex distribution, causes of ITP, treatment received, and remission status. The registry helps advance knowledge about ITP through long-term monitoring and standardized data collection.
