This clinical trial is focused on studying the treatment of hormone receptor-positive HER2-negative breast cancer that is either locally advanced or has spread to other parts of the body, known as metastatic breast cancer. The study will use a combination of medications, including Abemaciclib (also known by its code name LY2835219), which is taken orally as a film-coated tablet, and various types of endocrine therapy. Endocrine therapy involves medications that block or lower the amount of hormones in the body to slow down or stop the growth of cancer. The specific endocrine therapies being studied include Exemestane, Anastrozole, Letrozole, and Fulvestrant. These medications are used to manage the cancer by targeting the hormones that help the cancer grow.
The purpose of this study is to evaluate how well the combination of Abemaciclib and endocrine therapy works in managing the cancer and to focus on managing side effects using digital tools. Participants will be divided into two groups based on their previous treatment history. The study will monitor the time it takes for the cancer to progress or for the patient to pass away, which is known as progression-free survival. This will help researchers understand the effectiveness of the treatment. The study will also look at overall survival, which is the length of time patients live after starting the treatment, and the objective response rate, which measures how much the cancer shrinks or disappears after treatment.
Participants in the study will take the medications for a period of up to 36 months. The study will involve regular check-ups and assessments to monitor the cancer’s response to the treatment and any side effects experienced. The use of a digital health application is encouraged to help report side effects and other outcomes during the study. This trial aims to provide valuable information on the effectiveness and safety of combining Abemaciclib with endocrine therapy in treating hormone receptor-positive HER2-negative breast cancer.
