Researchers are evaluating the real-world effectiveness, safety, and patient compliance 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 ribociclib treatment with abemaciclib plus endocrine therapy and endocrine therapy alone, aiming to better understand treatment decisions and clinical adoption in routine practice. The study is conducted across breast centers and gynecological practices to represent typical healthcare settings. Participants receive treatment based on their physicians clinical judgment without randomization or intervention assignment. The study collects data from patients treated with ribociclib plus aromatase inhibitor with or without luteinizing hormone-releasing hormone LHRH, abemaciclib plus endocrine therapy with or without LHRH, or endocrine therapy alone with or without LHRH. Baseline data and follow-up information on adverse events, quality of life, treatment adherence, and socio-economic factors are gathered over time. During the study, participants undergo assessments including evaluation of invasive disease-free survival up to 36 months, quality of life questionnaires, medication adherence reports, and monitoring of adverse events and treatment changes. Data on reasons for treatment decisions, patient perceptions, and healthcare provider involvement are also collected. The study duration extends up to 39 months to provide a comprehensive overview of treatment impact and patient experience in real-world clinical settings.

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.

Researchers are investigating the effects of stopping CDK46 inhibitors in women with metastatic hormone receptor HR positive, HER2 negative breast cancer who have maintained disease control after long-term treatment. This phase II trial aims to evaluate whether disease stability continues when CDK46 inhibitors are discontinued after at least 12 months of combined treatment with endocrine therapy. The study is open-label, randomized, and conducted at multiple centers. Participants are randomly assigned to one of two groups one group continues both CDK46 inhibitor treatment such as Palbociclib or Abemaciclib and endocrine therapy, while the other group discontinues the CDK46 inhibitor but continues endocrine therapy alone. The study monitors disease progression and treatment effects over time, with a focus on how long patients remain free from disease worsening after stopping the CDK46 inhibitor. During the study, participants will be regularly assessed for disease progression, safety, and quality of life using questionnaires and clinical evaluations. Researchers will measure progression-free survival at 12 months and up to 54 months, time to treatment failure, time to first chemotherapy use, and monitor adverse events. The total participation duration may extend beyond four years, with ongoing evaluations to understand long-term outcomes and safety after stopping the CDK46 inhibitor.

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.
