This clinical trial is focused on studying breast cancer, a condition where cells in the breast grow uncontrollably. The trial aims to explore how different treatments can be personalized for individuals with high-risk breast cancer. The study will use several medications, including IBRANCE (available in 75 mg, 100 mg, and 125 mg hard capsules), which contains the active substance palbociclib. Palbociclib is a type of medication known as a CDK 4/6 inhibitor, which helps to stop cancer cells from growing. Another medication used in the study is Lynparza (150 mg film-coated tablets), which contains olaparib, a PARP-inhibitor that helps repair damaged DNA in cancer cells. Additionally, Perjeta (420 mg concentrate for solution for infusion) containing pertuzumab will be used, which is a type of protein that targets specific cancer cells.
The purpose of this study is to identify molecular markers that can predict how well a patient will respond to treatment and their survival outcomes. Participants will receive one or more of these medications, or a placebo, depending on their specific condition and treatment plan. The study will involve regular monitoring and assessments to track the progress of the disease and the effectiveness of the treatment. Participants will take the medications orally or through infusion, depending on the type of medication they are assigned. The trial will also involve taking biopsies, which are small samples of tissue, to study changes in the cancer cells during treatment.
The trial will last for several years, with participants receiving treatment for varying periods depending on their specific treatment plan. The study will help researchers understand how genetic and other factors influence the effectiveness of personalized treatments for breast cancer. By analyzing changes in tumor tissue and genetic material, the study aims to improve treatment strategies and outcomes for patients with high-risk breast cancer. The ultimate goal is to provide more effective and tailored treatment options for individuals with this condition.
