Platinum Sensitive Ovarian Carcinoma

This phase II trial studies if talazoparib works in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. All patients who take part on this study must have a gene aberration that changes how their tumors are able to repair DNA. This trial may help scientists learn whether some patients might benefit from taking different PARP inhibitors "one after the other" and learn how talazoparib works in treating patients with advanced cancer who have aberration in DNA repair genes.

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.
