A Study of Romosozumab in People With Breast Cancer and Osteoporosis

The researchers are doing this study to see if romosozumab is effective at helping with bone formation in people with metastatic breast cancer (MBC) that has spread to the bones. All participants will have osteoporosis. The researchers will also look at bone breakdown (resorption) in participants and determine if romosozumab is a safe treatment for osteoporosis in people with MBC that has spread to the bones.
