A Phase 2 Study of Cediranib in Combination With Olaparib in Advanced Solid Tumors

Open to people ages 18 years and up

• Patients must have histologically confirmed, metastatic or unresectable malignancy of the following types: (a) non-small cell lung cancer (NSCLC), (b) triple-negative breast cancer (TNBC; defined by estrogen receptor [ER] < 1%, progesterone receptor [PR] < 1% and HER2 1+ or less by immunohistochemistry [IHC]; if HER-2 expression is 2+, a negative fluorescence in situ hybridization [FISH] testing is required) (c) pancreatic adenocarcinoma (PDAC), or (d) small cell lung cancer (SCLC)
• Must have received at least one line of standard systemic treatment for locally advanced or metastatic disease setting of the respective tumor type; for NSCLC, it is either PD-1/PD-L1 inhibitor, or platinum-containing chemotherapy, or an EGFR tyrosine kinase inhibitor or an ALK inhibitor if sensitizing mutation present; TNBC: platinum-containing chemotherapy; PDAC: fluorouracil (5-FU-), gemcitabine-, or taxane-containing chemotherapy either with or without radiation therapy; SCLC: platinum-containing chemotherapy for limited or extensive stage disease
• Patients must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1
• Toxicities of prior therapy (except alopecia) should be resolved to =< grade 1 as per National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0; patients with long-standing stable grade 2 neuropathy or prior grade 2 treatment-related hypothyroidism requiring treatment, provided free T4 within normal range, may be considered eligible after discussion with the study principal investigator (PI)
• Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2 (Karnofsky >= 50%)

• Patients must be able to tolerate oral medications and not have gastrointestinal illnesses that would preclude absorption of cediranib or olaparib
• Adequately controlled thyroid function defined by free T4 within normal range, with no symptoms of thyroid dysfunction
• Adequately controlled blood pressure (BP) < 140 mmHg (systolic) and < 90 mmHg (diastolic) 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 3 antihypertensive medications; patients who are on 3 antihypertensive medications are highly recommended to be followed by a cardiologist or blood pressure specialist for management of BP while on protocol
• Patients who have the following risk factors are considered to be at increased risk for cardiac toxicities, and must have documented left ventricular ejection fraction (LVEF) by echocardiogram greater than institution's lower limit of normal (or 55% if threshold for normal not otherwise specified by institutional guidelines) obtained within 3 months
  • Prior treatment with anthracyclines
  • Prior treatment with trastuzumab
  • A New York Heart Association (NYHA) classification of II controlled with treatment
  • Prior central thoracic radiation therapy (RT), including RT to the heart
  • History of myocardial infarction within 12 months (patients with history of myocardial infarction within 6 months are excluded from the study)
• The effects of cediranib and olaparib on the developing human fetus are unknown; for this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and for 4 months after completion of cediranib and olaparib administration
• Ability to understand and the willingness to sign a written informed consent document
• Age >= 18 years. There is no dosing or adverse event data currently available on the use of cediranib or olaparib in patients < 18 years of age, thus excluding them from enrollment

• Patients who have had chemotherapy or RT within 3 weeks prior to start of the study agents, or those who have not recovered from adverse events due to agents administered more than 3 weeks earlier
• Patients should not have received any other investigational agents within the past 4 weeks
• Patients with untreated brain metastases, spinal cord compression, or evidence of symptomatic brain metastases or leptomeningeal disease as noted on computed tomography (CT) or magnetic resonance imaging (MRI) scans should be excluded from this clinical trial, since neurologic dysfunction may confound the evaluation of neurologic and other adverse events (AEs); screening brain MRI (or CT if MRI contraindicated) will be required for patients with recurrent NSCLC, TNBC, or SCLC; brain MRI (or CT if MRI contraindicated) is required for PDAC if clinically suspected by patient's symptoms or neurological exam; should patient found to have brain metastasis, treatment of brain metastasis must precede the participation in this study; for patients with known and treated brain metastases is allowed in this study if they fulfill the following criteria:
  • The lesions have improved or remained stable radiographically and clinically for at least 6 weeks after completion of brain irradiation or stereotactic brain radiosurgery and off steroids for at least 6 weeks
• Patients who have received prior inhibitor of VEGF signaling and a poly (ADP-ribose) polymerases (PARP) inhibitor administered in combination; unless administered in combination, patients who received a prior PARP inhibitor or a prior VEGF-signaling inhibitor agent are allowed after discussing with the PI
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to cediranib or olaparib
• Participants receiving any medications or substances that are strong inhibitors or inducers of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) are ineligible; dihydropyridine calcium-channel blockers are permitted for management of hypertension
• Current use of natural herbal products or other complementary alternative medications (CAM) or "folk remedies"
• Patients with concomitant or prior invasive malignancies within the past 3 years; subjects with treated limited stage basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the breast or cervix are eligible
• 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
• History of myocardial infarction within 6 months prior to registration
• History of stroke or transient ischemic attack within 6 months prior to registration
• NYHA classification of III or IV
• Current cardiac arrhythmia requiring concurrent use of anti-arrhythmic drugs

• Clinically significant peripheral vascular disease or abdominal aortic aneurysm (> 5 cm) or aortic dissection; if known history of abdominal aortic aneurysm with >= 4 cm in diameter, all of the following must be met:
  • An ultrasound (US) within the last 6 months prior to registration will be required to document that it is =< 5 cm
  • Patient must be asymptomatic from the aneurysm
  • Blood pressure must be well controlled as defined in this protocol
• A major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to starting cediranib (percutaneous/endobronchial biopsies are allowed)

• Patients may not have current dependency on intravenous (IV) hydration or total parenteral nutrition (TPN)
• Patients may not have evidence of coagulopathy or bleeding diathesis; therapeutic anticoagulation for prior thromboembolic events is permitted; the clinical indication for therapeutic anticoagulation must be clearly documented prior to enrollment and must be discussed with the P.I.; given the increases risk of serious bleeding from cediranib, patients who are on greater than or equal to 2 anti-thrombotic agents, including but not limited to anti-platelet agents (non-steroidal anti-inflammatory drugs [NSAIDs]/aspirin, clopidogrel), heparin, low molecular weight heparin (LMWH), warfarin, and a direct thrombin inhibitor, will be excluded
• Patients may not have features suggestive of myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML) on peripheral blood smear or bone marrow biopsy, if clinically indicated
• Pregnant women are excluded from this study because olaparib and cediranib have the potential for teratogenic or abortifacient effects; due to the fact that there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with olaparib and cediranib, breastfeeding should be discontinued if the mother is treated with cediranib and olaparib
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with cediranib or olaparib; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated; HIV-positive patients with undetectable viral loads and CD4 counts > 300, and not on any antiretroviral therapy may be allowed after discussing with the principle investigator
• Any condition that, in the opinion of the treating investigator would interfere with evaluation of the investigational product or interpretation of subject safety or study results
