Researchers are studying the real-world effectiveness, safety, and patient experience of ribociclib combined with an aromatase inhibitor for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. This observational study also compares patient compliance and quality of life among those treated with ribociclib, abemaciclib with endocrine therapy, or endocrine therapy alone. The goal is to understand treatment decisions and how these therapies perform in routine care settings. Participants receive treatment as prescribed by their doctors based on local guidelines and product information for ribociclib plus aromatase inhibitor with or without LHRH, abemaciclib with endocrine therapy plus or minus LHRH, or endocrine therapy alone plus or minus LHRH. There is no random treatment assignment since this is an observational study. Baseline data are collected shortly before or after treatment initiation depending on the cohort. During the study, patients will be followed for up to 36 months to monitor invasive disease-free survival and other health outcomes. Researchers will collect information on adverse events, treatment modifications, adherence measures, quality of life questionnaires, and socio-economic factors at various timepoints. This will provide insights into treatment tolerability, patient compliance, and overall impact on quality of life in a real-world setting.

Researchers are evaluating the real-world effectiveness of asciminib for adults with Philadelphia chromosome-positive chronic myeloid leukemia in the chronic phase Ph CML-CP. This includes patients who are newly diagnosed or have been treated before with one tyrosine kinase inhibitor TKI. The study aims to gather information on how well asciminib works and its tolerability and safety compared to other TKIs used in routine care. The study includes three groups patients treated with asciminib, newly diagnosed patients treated with imatinib, and newly diagnosed patients treated with second-generation TKIs such as dasatinib, bosutinib, or nilotinib. Treatment decisions are made by the patients doctor as part of routine care, and treatment must start no more than 14 days before joining the study or after the baseline assessment. Patients are followed over time while receiving their assigned treatments. Participants will attend routine follow-up visits and complete questionnaires about their health and quality of life throughout the study. Researchers will measure the percentage of patients achieving a major molecular response at 12 months as the main outcome. Additional outcomes include treatment adherence, dose changes, interruptions, discontinuations, and quality of life scores. The study will continue until September 2030 to monitor safety and effectiveness in real-world settings.

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.

Researchers are evaluating patient-reported outcomes and real-world data on the use of trastuzumab deruxtecan T-DXd in adults with HER2-positive, HER2-low, or HER2-ultralow unresectable or metastatic breast cancer. This observational study focuses on the effectiveness and safety of T-DXd as used in routine clinical practice in Germany, including how patients respond to the treatment over time. The study is non-interventional and involves patients receiving T-DXd according to approved guidelines. The study includes two groups one with patients having HER2-positive tumors and another with patients having HER2-low or HER2-ultralow tumors. All patients receive T-DXd treatment as recommended by the products summary of characteristics, and all medical decisions including treatment schedules are made by the treating physicians. Participants will also be informed about the use of a digital healthcare application DiGA to support their care. Participants will be observed for up to 60 months to track the time until the next treatment or death, whichever occurs first. Patient quality of life will be assessed six months after starting treatment using specific questionnaires FACT-B and FACT-G. Other data collected will include safety and efficacy outcomes reported during regular clinical visits. The study aims to enroll approximately 800 patients, with about 400 in each cohort, and will continue until the end of 2031.
