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 safety, effectiveness, and quality of life for combining Abemaciclib with either an Aromatase Inhibitor or Fulvestrant in women with metastatic hormone receptor-positive, HER2-negative breast cancer. This Phase IV trial focuses on both pre- and postmenopausal patients receiving first-line treatment. A digital health app called CANKADO will be used to track side effects and patient-reported outcomes daily, alongside standard documentation. The study also aims to explore biomarkers to better understand treatment responses and resistance. Participants will receive either Abemaciclib combined with an Aromatase Inhibitor Anastrozole, Letrozole, or Exemestane taken orally twice daily plus daily Aromatase Inhibitor tablets every 24 hours in 28-day cycles, or Abemaciclib with Fulvestrant which is given as an injection on specific days within 28-day cycles. The two treatment groups are experimental and non-randomized, with no masking. The trial includes monitoring for side effects and quality of life throughout treatment. During the study, participants will regularly report side effects and global health status using questionnaires at multiple time points up to 24 months, including specialized breast cancer quality of life modules. Researchers will assess progression-free survival up to 48 months, as well as adverse events, hospitalizations, clinical benefit rate, overall survival, and tumor response. The use of the CANKADO app for side effect reporting is strongly recommended but not mandatory. Participants will be followed for safety and outcomes throughout the trial duration.

Researchers are observing the real-world effects and patient experiences of trastuzumab deruxtecan T-DXd treatment in adults with HER2-positive, HER2-low, or HER2-ultralow unresectable or metastatic breast cancer. This prospective, non-interventional study takes place in multiple centers in Germany and aims to collect patient-reported outcomes along with safety and efficacy data during routine clinical practice. Approximately 800 patients will be enrolled, divided evenly between HER2-positive and HER2-lowultralow cohorts. Participants will receive T-DXd treatment as prescribed by their doctors according to the approved product guidelines SmPC. Treatment and visit schedules are determined by the treating physician and are not fixed by the study protocol. Patients will also be informed about using a digital healthcare application DiGA during the study. The study includes two cohorts based on HER2 status, both receiving T-DXd in routine care. During the study, participants will be followed to measure the time until their next treatment or death, assessed for up to 60 months from the first T-DXd dose. Quality of life will be evaluated using questionnaires at six months after baseline. Patient safety and treatment effects will be monitored through data collected in routine clinical visits. The total participation period may extend up to eight years, allowing for long-term observation of treatment outcomes in real-world settings.
