Testing the Combination of Cediranib and Olaparib in Comparison to Each Drug Alone or Other Chemotherapy in Recurrent Platinum-Resistant Ovarian Cancer

PRIMARY OBJECTIVES: I. To assess the efficacy and identify (in)active arm(s) of the combination of cediranib maleate (cediranib) and olaparib, cediranib alone, olaparib alone, and physician's choice standard of care chemotherapy, as measured by progression-free survival (PFS) in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase II) II. To assess the efficacy of the combination of cediranib and olaparib, and cediranib monotherapy, as measured by overall survival (OS) and PFS, as compared to physician's choice standard of care chemotherapy in women with recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III) SECONDARY OBJECTIVES: I. To assess the efficacy of the combination of cediranib and olaparib, cediranib alone, olaparib alone, and physician's choice standard of care chemotherapy, as measured by objective response rate (ORR: partial or complete response) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase II) II. To assess safety endpoints, as measured by frequency and severity of adverse events by Common Terminology Criteria for Adverse Events (CTCAE). (Phase II and Phase III) III. To assess the efficacy of the combination of cediranib and olaparib, and cediranib monotherapy, as measured by ORR as compared to physician's choice standard of care chemotherapy in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III) OBJECTIVES WITH INTEGRATED BIOMARKERS: I. To assess correlation of homologous recombination deficiency (HRD) status, as assessed via BROCA-HR assay with response, as measured by PFS and ORR. (Phase II) II. To evaluate the prognostic and predictive role of circulating endothelial cells (CEC) on comparative effectiveness of targeted therapies and reference chemotherapy. (Phase II) III. To evaluate quality of life data compliance, as measured by the 9-item Disease Related Symptoms (DRS-9) subscale of the National Comprehensive Cancer Network (NCCN)-Functional Assessment of Cancer Therapy (FACT) Ovarian Symptom Index (NFOSI) for utilization and analysis in the Phase III study. (Phase II) IV. To assess correlation of HRD status, as assessed via BROCA-HR assay with response, as measured by OS, PFS and ORR. (Phase III) V. To evaluate the prognostic and predictive role of circulating endothelial cells (CEC) on comparative effectiveness of targeted therapies and reference chemotherapy. (Phase III) VI. To assess the effect on disease-related symptoms (DRS) as measured by the 9-item DRS-P subscale of the NCCN-FACT Ovarian Symptom Index-18 (NFOSI-18), of single agent cediranib and cediranib/olaparib combination, compared to standard chemotherapy, in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III) EXPLORATORY OBJECTIVES: I. To assess exploratory biomarkers of potential HRD, including genomic scarring, BRCA1 methylation, BRCA1 protein expression, and mutations in NHEJ, and other genes that might modify HRD. (Phase II and Phase III) II. To evaluate the prognostic and predictive role of angiogenic biomarkers, as assessed by the Duke plasma angiome. (Phase II and Phase III) III. To assess the effect on secondary measures of quality of life, as assessed by the treatment side effects (TSE) and function/well-being (F/WB) subscales of the NFOSI-18, sensory neuropathy as measured by the FACT/GOG-Ntx-4, and health utility as measured by the EQ-5D, of single agent cediranib and cediranib/olaparib combination, compared to standard chemotherapy, in the setting of recurrent platinum-resistant or-refractory ovarian, primary peritoneal or fallopian tube cancer. (Phase III) 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.
