Testing the Combination of Olaparib and Durvalumab, Cediranib and Durvalumab, Olaparib and Capivasertib, and Cediranib Alone in Recurrent or Refractory Endometrial Cancer Following the Earlier Phase of the Study That Tested Olaparib and Cediranib in Comparison to Cediranib Alone, and Olaparib Alone

Running, not enrolling · Phase 2

Conditions studied: Endometrial Adenocarcinoma, Endometrial Mixed Cell Adenocarcinoma, Endometrial Serous Adenocarcinoma, Endometrial Undifferentiated Carcinoma, Endometrioid Adenocarcinoma, Stage IV Uterine Corpus Carcinoma or Carcinosarcoma AJCC v8

In brief

This phase II trial studies the effects of the combination of olaparib and durvalumab, cediranib and durvalumab, olaparib and capivasertib, and cediranib alone in treating patients with endometrial cancer that has come back (recurrent) or does not respond to treatment (refractory). Olaparib, cediranib, and capivasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Testing the combinations may lower the chance of endometrial cancer growing or spreading compared to usual care.

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Patients must have recurrent or persistent endometrial carcinoma, which is refractory to curative therapy or established treatments; histologic confirmation of the original primary tumor is required; patients with the following histologic epithelial cell types are eligible: endometrioid adenocarcinoma, serous adenocarcinoma, undifferentiated carcinoma, mixed epithelial carcinoma, adenocarcinoma not otherwise specified (N.O.S.); NOTE: clear cell and carcinosarcoma histology is excluded.
• Patients must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or non-measurable (detectable) disease
• Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded); each lesion must be >= 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI) or caliper measurement by clinical exam; or >= 20 mm when measured by chest x-ray; lymph nodes must be > 15 mm in short axis when measured by CT or MRI; patients with measurable disease must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST version 1.1; tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy
• Non-measurable (detectable) disease in a patient is defined in this protocol as one who does not have measurable disease but has at least one of the following conditions:
• Ascites and/or pleural effusion attributed to tumor;
• Solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST 1.1 definitions for target lesions.
• Patients must have signed an approved informed consent and authorization permitting release of personal health information.
• Patients must have had one prior chemotherapeutic regimen for management of endometrial carcinoma; initial treatment may include chemotherapy, chemotherapy and radiation therapy, and/or consolidation/maintenance therapy; chemotherapy administered in conjunction with primary radiation as a radio-sensitizer WILL be counted as a systemic chemotherapy regimen.
• Patients are allowed to receive, but are not required to receive, one additional cytotoxic regimen for management of recurrent or persistent disease according to the following definition: cytotoxic regimens include any agent that targets the genetic and/or mitotic apparatus of dividing cells, resulting in dose-limiting toxicity to the bone marrow and/or gastrointestinal mucosa; Note: patients on this non-cytotoxic study are allowed to receive one additional cytotoxic chemotherapy regimen for management of recurrent or persistent disease, as defined above; however, patients are encouraged to enroll on second-line non-cytotoxic studies prior to receiving additional cytotoxic therapy.
• Patients may have received non cytotoxic therapy including immunotherapy (1 prior line in either upfront or recurrent setting) but excluding cediranib, olaparib, AZD5363 (capivasertib), durvalumab (MEDI4736), or the combination of lenvatinib and pembrolizumab for the management of recurrent or persistent disease; prior hormonal therapy is allowed; hormonal therapy for grade 1 endometrial cancers with low volume or indolent disease is encouraged.
• Bevacizumab, or one course of single-agent immune-checkpoint therapy, excluding durvalumab (MEDI4736), is permitted prior to enrollment on this trial.
• Body weight > 30 kg.
• Age >= 18.
• The trial is open to females only (including women with an intact uterus with uterine cancer); fertile females of childbearing potential need to agree to use adequate contraceptive measures from 2 weeks prior to the study and until 1 month after study treatment discontinuation, and have a negative serum or urine pregnancy test within 3 days prior to the start of study treatment.
• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0,1 or 2 (Karnofsky >= 60%) within 7 days prior to registration; patients should have no deterioration over the previous two weeks.
• Hemoglobin >= 10 mg/dL with no blood transfusion in the past 28 days (within 28 days prior to administration of study drug).
• Platelet count >= 100 x 10\^9/L (within 28 days prior to administration of study drug).
• Absolute neutrophil count (ANC) >= 1.5 x 10\^9/L (within 28 days prior to administration of study drug).
• Patients must have creatinine clearance estimated of >= 51 mL/min using the Cockcroft Gault equation or based on a 24-hour urine test (within 28 days prior to administration of study drug).
• Serum bilirubin =< 1.5 X upper limit of normal (ULN) (within 28 days prior to administration of study drug).
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 x ULN (within 28 days prior to administration of study drug).
• Urinalysis (dipstick) =< 1+ proteinuria OR urine protein creatinine ratio (UPCR) < 1 (within 28 days prior to administration of study drug).
• Patients must be able to swallow and retain oral medications and without gastrointestinal illnesses that would preclude absorption of cediranib, olaparib, or AZD5363 (capivasertib).
• Patients must have adequately controlled blood pressure (BP), with a BP no greater than 140 mmHg (systolic) and 90 mmHg (diastolic) for eligibility; patients must have a BP of =< 140/90 mmHg taken in the clinic setting by a medical professional within 2 weeks prior to starting study; patients with hypertension may be managed with up to a maximum of three antihypertensive medications; it is strongly recommended that patients who are on three antihypertensive medications be followed by a cardiologist or blood pressure specialist for management of blood pressure while on protocol.
• Note: Patients must be willing and able to check and record daily blood pressure readings.

You may not qualify if…

• Prior enrollment into a clinical trial including cediranib or olaparib; Note: prior bevacizumab is not an exclusion criterion.
• Prior enrollment into a clinical trial including cediranib, olaparib, AZD5363 (capivasertib), durvalumab (MEDI4736), or the combination of lenvatinib and pembrolizumab. Note: Prior bevacizumab or single-agent immune checkpoint blockade, excluding durvalumab (MEDI4736), is not an exclusion criterion.
• Prior chemotherapy, endocrine therapy, radiotherapy, or investigational agents within 4 weeks.
• More than one prior line of treatment with immune checkpoint blockade therapy.
• Current signs/symptoms of bowel obstruction and/or signs/symptoms of bowel obstruction within the preceding 3 months.
• History of gastrointestinal perforation; patients with a history of abdominal fistula will be considered eligible if the fistula was surgically repaired or has healed, there has been no evidence of fistula for at least 6 months, and patient is deemed to be at low risk of recurrent fistula.
• Uncontrolled intercurrent illness including, but not limited to known ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or psychiatric illness/social situations that would limit compliance with study requirements.
• Concomitant use of known strong cytochrome (CYP) 3A inhibitors (e.g., itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil); the required washout period prior to starting study treatments is 2 weeks for strong inhibitors, and at least 1 week for moderate inhibitors.
• Concomitant use of potent inhibitors or inducers of CYP3A4 within 2 weeks before the start of study treatment (3 weeks for St John's wort), or sensitive substrates of CYP3A4, CYP2C9 and/or CYP2D6 with a narrow therapeutic window within 1 week before the start of study treatment. Concomitant use of drugs known to prolong the QT interval within 5 half-lives of the first dose of study treatment.
• 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; for women of childbearing capacity a negative pregnancy test is required.
• Known human immunodeficiency virus (HIV)-positive individuals are ineligible because of the potential for pharmacokinetic interactions between many anti-HIV drugs and cediranib, olaparib, and/or AZD5363 (capivasertib); in addition, these individuals are at increased risk of lethal infections when treated with marrow-suppressive therapy.
• Known active hepatitis B or hepatitis C infection on antiviral treatment.
