A Phase II Evaluation of Pembrolizumab in Combination with IV Bevacizumab and Oral Metronomic Cyclophosphamide in the Treatment of Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer
This phase II trial studies the combination of pembrolizumab, bevacizumab, and low dose oral cyclophosphamide in treating patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer. Monoclonal antibodies, such as pembrolizumab and bevacizumab, may block tumor growth in different ways such as boosting your own immune system to find, recognize and kill tumor cells as well as by blocking the growth of new blood vessels necessary for tumor growth and nutrition. Drugs used in chemotherapy, such as low dose oral cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, as well as by further enhancing your own body's immune response against cancer cells. As these three drugs have all been shown to improve the immune response against cancer cells giving pembrolizumab, bevacizumab, and cyclophosphamide together may work better in treating patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer.
