    Synopsis: This study has two parts: A Phase II part and a Phase III part. You are being asked to participate in the Phase III part of the study. The purpose of the Phase II part of the study is to compare any good and bad effects of using a combination of the experimental drugs cediranib and olaparib, to using the standard chemotherapy, or cediranib alone, or olaparib alone. The Phase III study will follow the Phase II to confirm the effectiveness of a combination of cediranib and olaparib to the standard chemotherapy. One of the experimental drugs, either cediranib or olaparib alone may be compared with the standard chemotherapy for the effectiveness, after reviewing the results from Phase II study. Cediranib is an experimental drug that may help keep cancer cells from growing by affecting their blood supply. Olaparib is a drug that may stop cancer cells from growing abnormally. Olaparib by itself has been approved by the Food and Drug Administration (FDA) for use in women with advanced ovarian cancer with BRCA1 and BRCA2 mutations (defined below) who have been treated with three or more different chemotherapy treatments. The combination of olaparib and cediranib is investigational. These drugs have been used in other research studies in ovarian cancer, and information from those other research studies suggest that these may help to keep cancer from growing. The addition of cediranib to olaparib could shrink your cancer but it could also cause side effects. This study will allow the researchers to know whether this different approach using two study drugs is better, the same, or worse than the usual chemotherapy approach. Standard chemotherapy drugs that are already FDA-approved for use in recurrent ovarian cancer include paclitaxel, topotecan, or pegylated liposomal doxorubicin (PLD).

    Another purpose of this study is for researchers to learn if a biomarker test is helpful to decide whether or not a patient’s tumor will respond to the study drug(s). Tissue from your surgery will be used for the biomarker test. Extra tubes of blood will also be drawn for the biomarker test. Researchers do not know if using the biomarker test is better, the same, or worse than if you enrolled in this study without using the biomarker test.

    The biomarker test will be done to study gene mutations using a sample from the tissue that was collected at the time of your surgery or biopsy and from a blood sample collected before you start treatment. Also, two additional blood samples will be collected before and three days after you begin treatment to study changes in cells that have been shed from the lining of the vascular wall into the blood stream related to blood vessel injury, and to investigate proteins related to tumor growth, blood vessel formation and inflammation.
