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 addition of Tersolisib LY4064809STX-478 to other anti-cancer drugs as a first treatment for adults with advanced hormone receptor-positive HRhuman epidermal growth factor receptor 2-negative HER2- breast cancer that has a PIK3CA mutation. This Phase 3 randomized, double-blind, placebo-controlled trial aims to understand the efficacy and safety of this combination compared to placebo, focusing on improving outcomes for patients with this specific genetic change. Participants receive LY4064809 orally in one of two doses combined with a CDK46 inhibitor such as Ribociclib, Palbociclib, or Abemaciclib and endocrine therapy ET administered orally or via intramuscular injection. The comparison group receives a placebo combined with the same CDK46 inhibitor and ET. The study includes two parts Part 1 explores dose optimization, and Part 2 evaluates the treatment combinations effectiveness and safety as a first-line therapy. During the study, participants will have regular assessments to monitor cancer response, progression, and safety over an estimated period of up to 5 years or more. Researchers will measure outcomes such as overall response rate, progression-free survival, duration of response, overall survival, and quality of life. Treatment continues as long as the cancer benefits without intolerable side effects. Safety monitoring, laboratory tests, and quality of life questionnaires are part of the participant involvement throughout the trial.
