NRG-GY009

This randomized phase II / III trial studies how well pegylated liposomal doxorubicin hydrochloride with atezolizumab and / or bevacizumab work in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back. Drugs used in chemotherapy, such as pegylated liposomal doxorubicin hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. block tumor growth Monoclonal antibodies, such as atezolizumab and bevacizumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known which combination will work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

NRG-GY014 – Temporarily Closed

This phase II trial studies how well tazemetostat works in treating patients with ovarian, primary peritoneal, or endometrial cancer that has come back. Drugs used in chemotherapy, such as tazemetostat, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

NRG-GY019

This phase III trial studies how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body which in turn may stop the growth of tumor cells that need estrogen to grow. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving letrozole alone or in combination with paclitaxel and carboplatin works better in treating patients with low-grade serous carcinoma of the ovary or peritoneum compared to paclitaxel and carboplatin without letrozole.

NRG-GY023

This phase II trial studies the possible benefits of treatment with different combinations of the drugs durvalumab, olaparib and cediranib vs. the usual treatment in patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back after a period of improvement with platinum therapy (recurrent platinum resistant). Usual treatment is the type of treatment most patients with this condition receive if they are not part of a clinical study. Combination therapies studied in this trial include MEDI4736 (durvalumab) plus olaparib and cediranib, durvalumab and cediranib, or olaparib and cediranib. Monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumors cells to grow and spread. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Cediranib may stop the growth of tumor cells by blocking VEGF (an enzyme). needed for cell growth. Giving different combinations of durvalumab, olaparib and cediranib may work better in increasing the duration of time that the cancer does not progress compared to the usual treatment.
