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.

This research investigates GLSI-100 immunotherapy in people with HER2neu positive breast cancer who are at high risk for their cancer returning. It focuses on participants who have completed both neoadjuvant and postoperative adjuvant standard treatments. The study is Phase 3, randomized, double-blinded, and placebo-controlled, involving subjects who are HLA-A*02 positive as well as an open-label group of non-HLA-A*02 positive subjects. The goal is to evaluate the treatments impact on invasive breast cancer-free survival over a median follow-up of 4 years. Participants receive 6 primary immunization injections of GLSI-100 or placebo intradermally once a month for the first 6 months, followed by 5 booster injections spaced 6 months apart, totaling 11 injections over 3 years. There are three groups one receiving placebo 0.9% normal saline, one receiving GLSI-100 immunotherapy in HLA-A*02 positive subjects, and an open-label arm for non-HLA-A*02 positive subjects receiving GLSI-100 under the same schedule. During the study, participants undergo regular monitoring and assessments including invasive disease-free survival, distant disease-free survival, overall survival, and quality of life questionnaires at baseline and up to 36 months. Researchers track safety and treatment effects over a median 4-year follow-up. The study continues until December 2031, aiming to provide comprehensive data on long-term outcomes and quality of life for participants receiving these treatments.

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.
