Pembrolizumab Combined With Bevacizumab With or Without Agonist Anti-CD40 CDX-1140 for the Treatment of Patients With Recurrent Ovarian Cancer

This phase II trial tests whether pembrolizumab combined with bevacizumab with or without agonist anti-CD40 CDX-1140 works to shrink tumors in patients with ovarian cancer that has come back (recurrent). Anti-CD40 CDX-1140 works by stimulating certain immune cells within the tumor and, when combined with other immunotherapy treatments, may increase antitumor antibody production. Immunotherapy with monoclonal antibodies, such as pembrolizumab and bevacizumab, may help the body's immune system, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab and bevacizumab with anti-CD40 CDX-1140 may decrease symptoms, prolong survival, and improve quality of life in patients with ovarian cancer.
