Summary

This randomized phase II/III trial studies how well cediranib maleate and olaparib work when given together or separately, and compares them to standard chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has returned (recurrent) after receiving chemotherapy with drugs that contain platinum (platinum-resistant) or continued to grow while being treated with platinum-based chemotherapy drugs (platinum-refractory). Cediranib maleate and olaparib may stop the growth of tumor cells by blocking enzymes needed for cell growth. Chemotherapy drugs 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 cediranib maleate and olaparib together may cause more damage to cancer cells when compared to either drug alone or standard chemotherapy.

OUTLINE:

PHASE II: Patients are randomized to 1 of 4 treatment arms.

ARM I (REFERENCE REGIMEN): Patients undergo physician's choice of standard of care chemotherapy, comprising either paclitaxel intravenously (IV) over 60 minutes on days 1, 8, 15, and 22 every 28 days (Regimen I); pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1 every 28 days (Regimen II); or topotecan hydrochloride IV over 30 minutes on days 1, 8, and 15 every 28 days or days 1-5 every 21 days (Regimen III). Treatment continues in the absence of disease progression or unacceptable toxicity. No modification of the assigned regimens, such as additional drugs (gemcitabine, or bevacizumab) is allowed. Patients also undergo computed tomography (CT) and magnetic resonance imaging (MRI) throughout the study. (12/05/2016)

ARM II (CEDIRANIB MALEATE AND OLAPARIB): Patients receive cediranib maleate orally (PO) once daily (QD) and olaparib PO twice daily (BID). Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and MRI throughout the study.

ARM III (CEDIRANIB): Patients receive cediranib maleate PO daily continuously. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and MRI throughout the study.

ARM IV (OLAPARIB): Patients receive olaparib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and MRI throughout the study. (In July 2018, the Data Monitoring Committee voted to exclude the olaparib alone regimen).

PHASE III: Patients are randomized to 1 of 3 treatment arms.

ARM I (REFERENCE REGIMEN): Patients undergo physician's choice standard of care chemotherapy as in Phase II Arm I. No modification of the assigned regimens, such as additional drugs (gemcitabine or bevacizumab) is allowed. Patients also undergo CT and MRI throughout the study. (12/05/2016)

ARM II (CEDIRANIB AND OLAPARIB): Patients receive cediranib maleate PO and olaparib PO as in Phase II Arm II. Patients also undergo CT and MRI throughout the study.

ARM III (SINGLE AGENT): Patients receive cediranib maleate PO as determined by the Phase II study. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and MRI throughout the study.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for up to 3 years.
