Study Summary
This trial is testing tamoxifen citrate or letrozole with or without bevacizumab to treat stage IIIB or IV breast cancer. Estrogen fuels breast cancer cell growth, so hormone therapy with tamoxifen or letrozole can block estrogen and stop tumor growth. Bevacizumab is an immunotherapy that may help the body's immune system fight the cancer. Researchers want to see if it is more effective with or without bevacizumab.
Who is the study for?
This trial is for postmenopausal women or premenopausal women on ovarian suppression with stage IIIB or IV breast cancer that responds to hormones. Participants should not have had major surgery recently, no history of significant bleeding, fistulas, or abdominal abscesses, and no severe cardiovascular issues. They must have a life expectancy of at least 12 weeks and be in good physical condition (ECOG <=1).Check my eligibility
What is being tested?
The study is testing the effectiveness of hormone therapies tamoxifen citrate or letrozole alone versus combined with the monoclonal antibody bevacizumab in advanced breast cancer. The goal is to see if adding bevacizumab improves outcomes by altering the immune system's response to tumor cells.See study design
What are the potential side effects?
Bevacizumab can cause high blood pressure, increased risk of bleeding and blood clots, headaches, mouth sores, and proteinuria (excess protein in urine). Tamoxifen may lead to hot flashes, vaginal discharge or bleeding, and an increased risk of blood clots. Letrozole side effects include bone pain, cholesterol changes, fatigue.
