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 observing adults with Chronic Lymphocytic Leukemia CLL who are receiving the drug venetoclax, either alone or combined with other medications such as rituximab, obinutuzumab, ibrutinib, or acalabrutinib. The study aims to understand how these treatments work in real-life settings, focusing on the effectiveness, costs related to health economics, and outcomes reported by the patients themselves. Participants receive venetoclax as prescribed by their doctors following local medical guidelines. They may receive it alone or alongside one of the other drugs mentioned. This study does not assign treatments but observes patients as they undergo therapy according to routine clinical practice across several countries. During the study, participants are monitored for their response to treatment, with the main focus on the best overall response rate within 12 months. Researchers collect data on health outcomes, costs, and patient experiences to better understand the impact of these therapies. The study spans several years, allowing long-term observation of treatment effects and outcomes.
