Researchers are evaluating the effectiveness of camizestrant compared to standard endocrine therapy in patients with early breast cancer that is estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-). These patients have an intermediate or high risk of cancer recurrence and have already completed local treatments such as surgery and possibly chemotherapy, alongside at least 2 years and up to 5 years of standard adjuvant endocrine therapy. The study is a Phase III, open-label trial designed to assess outcomes over a long term. Participants will be randomly assigned to receive either camizestrant, an oral selective estrogen receptor degrader, or one of several standard endocrine therapies including tamoxifen, anastrozole, letrozole, or exemestane, administered according to local approved guidelines. The treatment duration for both groups is planned to last 60 months. Eligible patients may have previously used CDK4/6 inhibitors, and the study will specifically include those with intermediate or high risk of recurrence as determined by clinical and biological markers. During the study, participants will be monitored for up to 10 years from the last patient's randomization to evaluate invasive breast cancer-free survival. Additional outcomes include invasive disease-free survival, distant relapse-free survival, overall survival, safety, and clinical outcome assessments. The study involves ongoing assessments of health status, treatment effects, and safety to determine the long-term benefits and risks of camizestrant compared to standard therapies.

This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm of the study is 7 years. Eligible patients must have intermediate-high or high risk of recurrence as defined by specified clinical and biologic criteria. Concurrent use of abemaciclib is permitted in both arms. The primary endpoint of the study is Invasive breast cancer-free survival (IBCFS) and main secondary endpoints include Invasive disease-free survival (IDFS), Distant relapse-free survival (DRFS), Overall survival (OS), Safety and Clinical Outcome Assessments (COAs). Patients will be followed for 10 years from randomization of the last patient.

Researchers are evaluating eye health in patients with breast cancer through a multicenter study. The study aims to assess ophthalmic safety by comparing two groups of patients concurrently to account for age-related changes and worsening of existing eye conditions. The study period for ophthalmic assessments will last approximately 12 months to minimize additional burden on participants. The study includes two parallel cohorts, each with at least 60 participants. Ophthalmic examinations will be conducted at the same time points for both groups. These assessments involve tests such as visual acuity using Snellen units, slit lamp examinations, optical coherence tonometry, and fundus examinations to monitor eye health. Participants will undergo ophthalmic evaluations performed by local ophthalmologists and central readers up to 28 days after the study ends. These evaluations include eye scans and detailed eye health reviews. The study monitors changes in vision and eye structure and safety throughout the 12-month period, ensuring participants' eye health is closely observed.
