About this trial
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.
Eligibility criteria
Qualifiers
≥18 years of age at the time of giving informed consent;
Patients diagnosed with hormone-receptor positive (ER/PR >1%) metastatic breast cancer to bones on any endocrine therapy with or without targeted therapy (i.e. CDK 4/6 inhibitors, PI3K inhibitors, anti-HER2-therapy);
osteoporosis on dual X-ray absorptiometry (DXA) scan; or history of fragility fracture of the spine or hip; or of morphometric spine fracture;
Disqualifiers
Prior therapy with a bone-modifying agent (intraveous bisphosphonates or subcutaneous denosumab) for metastatic bone disease;
25 (OH) vitamin D levels < 20 ng/mL; Vitamin D repletion will be permitted and subjects will be be rescreened once 25 (OH) vitamin D level ³ 20 ng/mL;
History of myocardial infarction or stroke within the preceding year;
