Recurrent platinum-resistant or refractory ovarian cancer is defined as the recurrence of ovarian cancer within 6 months after platinum-containing chemotherapy or worsening during platinum-containing chemotherapy. Researchers want to test if two study drugs treat this cancer better than one of the study drugs alone or standard chemotherapy. The study drugs are cediranib and olaparib. They also want to see if biomarker tests predict tumor response to the drugs.

Objectives:

To test if cediranib and olaparib treat platinum-resistant or refractory ovarian cancer better than one of them alone or standard chemotherapy. This study also includes platinum-resistant or refractory peritoneal, or fallopian tube cancer. To see if biomarker tests predict if tumors will respond to these drugs.

Eligibility:

Women ages 18 and older with certain recurrent platinum-resistant or refractory cancers

Design:

Participants will be screened with:

Medical history

Physical exam

X-rays and scans

Blood, urine, and heart tests

Tissue sample from past surgery or biopsy

Participants will be in a group in either Phase II or III.

Phase II:

Group 1: Standard chemotherapy by vein every 1 4 weeks

Groups 2 4: Tablets of one or both study drugs, up to 3 times a day.

Phase III:

Group 1: Standard chemotherapy by vein every 1 4 weeks

Groups 2 and 3: Tablets of both study drugs or one of the study drugs, a total of 3 times a day.

Some participants will keep a dairy of their drugs or blood pressure.

Participants will repeat screening tests every 2 4 weeks.

Participants will stay in the study as long as the drugs help them.

After treatment, participants will have a few visits a year for 5 years. Then they will have yearly phone calls for as long as they live.

Eligibility

INCLUSION CRITERIA

A patient cannot be considered eligible for this study unless ALL of the following conditions are met.

- Patients must have histologically or cytologically confirmed ovarian cancer, peritoneal cancer or fallopian tube cancer and must have a histological diagnosis of either serous or endometrioid cancer based on local histopathological findings. Both endometrioid and serous histology should be high-grade for eligibility of non-mutation carriers. Participants with a deleterious germline BRCA-mutation on a commercial CLIA assay with other high-grade histologies, including clear cell, transitional cell, undifferentiated adenoca, mixed epithelial andenoca are also eligible. Due to the long acceptance of BRCA testing through Myriad, Myriad testing will be accepted. If testing for BRCA is done by other organizations, genetic consultation report from a qualified medical professional listing the mutation and confirming that the laboratory results showed a recognized germ line deleterious BRCA 1 or BRCA 2 mutation or BRCA rearrangement is required. A copy of Myriad or other BRCA mutational analysis (positive or VUS or negative) reports will be requested.

- Patients should have recurrent platinum-resistant or- refractory disease - defined as disease that has progressed while receiving platinum or had recurrence within 6 months of the last receipt of platinum-based chemotherapy

- Phase II study: measurable disease by RECIST 1.1 criteria. Baseline biopsy for RP2 study is optional but highly encouraged.

- Phase III study: evaluable disease defined as RECIST 1.1 measurable disease OR non-measurable disease (defined as solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST 1.1 definitions for target lesions OR ascites and/or pleural effusion that has been pathologically demonstrated to be disease-related in the setting of a CA125 greater than or equal to 2x ULN).

- Prior therapy:

-- No more than 2 prior treatment regimens (including primary therapy). Hormonal therapies used as single agents (i.e. tamoxifen, aromatase inhibitors) will not count towards this line limit.

-- Patients may not have had a prior anti-angiogenic agent in the recurrent setting. Prior use of bevacizumab in the upfront or upfront maintenance setting is allowed.

-- Patients may not have previously received a PARP-inhibitor.

- Patient must have provided study specific informed consent prior to study entry.

- ECOG performance status 0 or 1 or 2.

- Patients must have adequate organ and marrow function as defined below

-- Absolute neutrophil count greater than or equal to 1,500/mcL

-- Platelets greater than or equal to 100,000/mcL

-- Hemoglobin greater than or equal to 10 g/dL

-- Total bilirubin less than or equal to 1.5 times the upper limit of normal (ULN) institutional limits

-- AST (SGOT)/ALT (SGPT) less than or equal to 2.5 (SqrRoot) institutional ULN. If intrahepatic liver metastases are present, AST and ALT must be less than or equal to 5 times institutional ULN.

-- Creatinine less than or equal to 1.5 X the institutional ULN

-- Urine protein: creatinine ratio (UPC) of less than or equal to 1 OR less than or equal to 2+ proteinuria on two consecutive dipsticks taken no less than 1 week apart. UPC is the preferred test. Patients with 2+ proteinuria on dipstick must also have a 24-hour urine collection demonstrating protein of less than or equal to 500mg over 24 hours.

- Toxicities of prior therapy (excepting alopecia) should be resolved to less than or equal to Grade 1 as per CTCAE v4.0 with long-standing stable grade 2 neuropathy may be considered after discussion with the Study Chair.

- Adequately controlled blood pressure (SBP less than or equal to 140; DBP less than or equal to 90mmHg) on maximum of three antihypertensive medications. Patients must have a BP of less than or equal to 140/90 mmHg taken in the clinic setting by a medical professional within 2 weeks prior to starting study. It is strongly recommended that patients who are on three antihypertensive medications be followed by a cardiologist or a primary care physician for management of BP while on protocol. Patients must be willing and able to check and record daily blood pressure readings.

- Adequately controlled thyroid function, with no symptoms of thyroid dysfunction and TSH within normal limits.

- Patients with treated limited stage basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the breast or cervix are eligible. Subjects with early-stage cancer treated with a curative intent with no evidence of recurrent disease 5 years following diagnosis and judged by the investigator to be at low risk of recurrence are eligible. Patients who have the following risk factors are considered to be at increased risk for cardiac toxicities. These patients should have increased monitoring: 1) prior treatment with anthracyclines, 2) prior treatment with trastuzumab, 3) a New York Heart Association classification of II controlled with treatment, 4) prior central thoracic radiation therapy (RT), including RT to the heart, 5) history of myocardial infarction within 12 months (patients with history of myocardial infarction within 6 months are excluded from the study).

- Able to swallow and retain oral medications and without GI illnesses that would preclude absorption of cediranib or olaparib.

- Age greater than or equal to 18 years

- Cediranib has been shown to terminate fetal development in the rat, as expected for a process dependent on VEGF signaling. For this reason, women of child-bearing potential must have a negative pregnancy test prior to study entry. Women of child-bearing potential must agree to use two reliable forms of contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 6 weeks after cediranib discontinuation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

- Olaparib adversely affects embryofetal survival and development in the rat. For this reason, women of child-bearing potential must have a negative pregnancy test prior to study entry. Women of child-bearing potential must agree to use must agree to use two reliable forms of contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 3 months after the last dose of olaparib. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

EXCLUSION CRITERIA

Patients with one or more of the following conditions are NOT eligible for this study.

- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. Patients may not have had hormonal therapy within 2 weeks prior to entering the study. Patients receiving raloxifene for bone health as per FDA indication may remain on raloxifene absent other drug interactions.

- Any other investigational agents within the past 4 weeks.

- Prior treatment affecting the VEGF/VEGFR pathway or the angiopoietin pathway in the recurrent setting, including but not limited to thalidomide, bevacizumab, sunitinib, sorafenib, pazopanib, cediranib, nintedanib, and trebananib. Bevacizumab used in the upfront setting in conjunction with chemotherapy and/or as maintenance to treat newly diagnosed disease will be allowed.

- Prior use of PARP-inhibitors.

- CA-125 only disease without RECIST 1.1 measurable or otherwise evaluable disease.

- Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to starting cediranib.

- Current signs and/or symptoms of bowel obstruction or signs and/or symptoms of bowel obstruction within 3 months prior to starting study drugs

- History of intra-abdominal abscess within the past 3 months.

- History of gastrointestinal perforation. Patients with a history of abdominal fistula will be considered eligible if the fistula was surgically repaired, there has been no evidence of fistula for at least 6 months, and patient is deemed to be at low risk of recurrent fistula.

- Dependency on IV hydration or TPN.

- Any concomitant or prior invasive malignancies with the following curatively treated exceptions:

-- Treated limited stage basal cell or squamous cell carcinoma of the skin.

-- Carcinoma in situ of the breast or cervix.

-- Primary endometrial cancer meeting the following conditions: Stage not greater than IA, grade 1 or 2, no more than superficial myometrial invasion, without vascular or lymphatic invasion; no poorly differentiated subtypes, including papillary serous, clear cell, or other FIGO grade 3 lesions

-- Prior cancer treated with a curative intent with no evidence of recurrent disease 5 years following diagnosis and judged by the investigator to be at low risk of recurrence.

- Patients with untreated brain metastases, spinal cord compression, or evidence of symptomatic brain metastases or leptomeningeal disease as noted on CT or MRI scans should not be included on this study, since neurologic dysfunction may confound the evaluation of neurologic and other adverse events. Patients with treated brain metastases and resolution of any associated symptoms must demonstrate stable post-therapeutic imaging for at least 6 months following therapy prior to starting study drug.

- Patients with any of the following:

-- History of myocardial infarction within six months

-- Unstable angina

-- Resting ECG with clinically significant abnormal findings.

-- New York Heart Association functional classification of III or IV

- If cardiac function assessment is clinically indicated or performed: LVEF less than normal per institutional guidelines, or <55%, if threshold for normal not otherwise specified by institutional guidelines.

Patients with the following risk factors should have a baseline cardiac function assessment:

-- Prior treatment with anthracyclines

-- Prior treatment with trastuzumab

-- Prior central thoracic radiation therapy (RT), including RT to the heart

-- History of myocardial infarction within 6 to 12 months (Patients with history of myocardial infarction within 6 months are excluded from the study)

-- Prior history of impaired cardiac function

- History of stroke or transient ischemic attack within six months

- Clinical significant peripheral vascular disease or vascular disease (aortic aneurysm or aortic dissection)

- Evidence of coagulopathy or bleeding diathesis. Therapeutic anticoagulation for prior thromboembolic events is permitted.

- Evidence suggestive of myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML) on peripheral blood smear or bone marrow biopsy, if clinically indicated.

No prior allogeneic bone marrow transplant or double umbilical cord blood transplantation (dUBCT).

- Patients may not use any complementary or alternative medicines including natural herbal products or folk remedies as they may interfere with the effectiveness of the study treatments.

- Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

- Known HIV-positive individuals are ineligible because of the potential for pharmacokinetic interactions with cediranib or olaparib. In addition, these individuals are at increased risk of lethal infections when treated with marrow-suppressive therapy.

- Participants receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 are ineligible. Refer to a frequently updated drug information reference for a list of strong inducers and inhibitors.

- Pregnant women are excluded from this study because cediranib and olaparib are agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with cediranib and olaparib, breastfeeding should be discontinued if the mother is treated with cediranib or olaparib. These potential risks may also apply to other agents used in this study.
