This study investigates the effectiveness of an investigational medication, alone or in combination with another treatment, in treating breast cancer that has spread to other parts of the body. Breast cancer can be described as a disease where cells in the breast grow out of control, and when it spreads, it is known as metastatic breast cancer. The purpose of this study is to determine how well these treatments work and to observe any side effects that may occur.
Participants in this study will receive either the investigational medication alone or with another treatment. The study will monitor the effects of these treatments on breast cancer and assess any side effects. This will help researchers understand how the treatment impacts the disease.
- Who can participate: Females aged 18 years or older with inoperable locally advanced or metastatic ER+ breast cancer are eligible to participate.
- Study details: Participants will receive either the investigational medication alone or with another treatment. A placebo, an inactive substance that looks like the investigational medicine but does not contain any medicine, will not be used in this study.
