(within 28 days prior to administration of therapy)
- Ability to swallow and retain oral medication
- The effects of olaparib and cediranib on the developing human fetus are unknown; for
this reason and because other therapeutic agents used in this trial are known to be
teratogenic, women of child-bearing potential and male patients and their partners who
are sexually active must agree to use two highly effective forms of contraception in
combination for the duration of study participation and for 3 months after completion
of olaparib and cediranib administration; 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
- Postmenopausal or evidence of non-pregnant status for women of childbearing potential
as confirmed by a negative urine or serum pregnancy test within 7 days prior to the
start of therapy; postmenopausal status is defined as:

- Age < 60 with any one or more of the conditions below:
- Amenorrheic for >= 1 year in the absence of chemotherapy and/or hormonal
treatments,
- Luteinizing hormone and/or follicle stimulating hormone and/or estradiol
levels in the post-menopausal range,

140 mmHg and diastolic blood pressure [DBP] of =< 90 mmHg) on maximum of three
antihypertensive medications; participants must have a blood pressure (BP) of =<
140/90 taken in the clinic or hospital setting by a medical professional within 2
weeks prior to starting on study; it is strongly recommended that participants who are
on 3 antihypertensive medications be followed by a cardiologist or a primary care
physician for management of BP while on study
- Adequately controlled thyroid function, with no symptoms of thyroid dysfunction;
patients can be on thyroid hormone replacement medication; asymptomatic patients with
elevated thyroid stimulating hormone (TSH) with normal T4/T3 are allowed to enroll,
and recommended to follow with routine thyroid function test
Exclusion Criteria:
- Patients who have had major surgery or trauma within 28 days prior to entering the
study; patients must have recovered from any effects of any major surgery and surgical
wound should have healed prior to starting treatment
- Patients who have had radiotherapy within 14 days prior to entering the study
- Patients with a non-healing wound, fracture, or ulcer
- Patients who have not recovered from adverse events due to prior anti-cancer therapy
(i.e., have residual toxicities > Common Terminology Criteria for Adverse Events
[CTCAE] grade 1 or baseline, with the exception of alopecia)
- Patients who are receiving any other investigational agents
- Patients with symptomatic central nervous system (CNS) metastases or leptomeningeal
carcinomatosis should be excluded from this clinical trial because of their poor
prognosis and because they often develop progressive neurologic dysfunction that would
confound the evaluation of neurologic and other adverse events; exceptions include
patients with previously-treated CNS metastases or those with are asymptomatic,
subcentimeter metastases, and have no requirement for steroids or anti-seizure
medication for at least one week prior to study entry; screening with CNS imaging
studies (CT scan or MRI) is required
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to olaparib, cediranib, carboplatin, cisplatin, or etoposide
- Patients with a history of myelodysplastic syndrome (MDS)
- Patients with a history of acute myeloid leukemia (AML), or patients with a history of
any other primary malignancy within 3 years prior to initiation of treatment on this
study; exceptions include: patients with a history of malignancies (other than AML)
that were treated curatively and have not recurred within 3 years prior to study
entry; resected basal and squamous cell carcinomas of the skin; and completely
resected carcinoma in situ of any type
- Patients with clinically significant gastrointestinal abnormalities including, but not
limited to:
- Clinically significant signs and/or symptoms of bowel obstruction within 3 months
prior to starting treatment
- History of intra-abdominal abscess within 3 months prior to starting treatment
- History of gastrointestinal (GI) perforation within 6 months prior to starting
treatment
- Evidence of abdominal fistula within 6 months prior to starting treatment;
history of abdominal fistula will be considered eligible if the fistula was
surgically repaired, and there has been no evidence of fistula for at least 6
months prior to starting treatment, and patient is deemed to be at low risk of
recurrent fistula
- Patients with a history of cerebrovascular accident including transient ischemic
attack (TIA), pulmonary embolism or insufficiently treated deep venous thrombosis
(DVT) within the past 3 months; Note: Participants with recent DVT who have been
treated with therapeutic anti-coagulants for at least 6 weeks are eligible, with the
exception of participants being treated with warfarin, which is prohibited on this
study; other oral anti-coagulants may be allowed after discussion with overall
principal investigator (PI), but short half-life low molecular weight heparins are
strongly preferred
- Patients with evidence of active bleeding diathesis
- Patients with hemoptysis in excess of 2.5 mL within 6 weeks prior to the first dose of
study medication
- Patients receiving any medications or substances that are potent inhibitors or
inducers of CYP3A4 are ineligible; the required washout period for strong inhibitors
is 2 weeks and at least one week for moderate inhibitors; the required washout period
prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 4 weeks
for other agents
- Patients requiring concomitant therapy with phenytoin, phenobarbital, carbamazepine,
or valproic acid
- 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; specifically, patients with any of the following within 6 months
prior to starting treatment are excluded:
- Acute myocardial infarction
- Unstable angina
- New York Heart Association functional classification of III or IV
- Left ventricular ejection fraction (LVEF) < lower limit of normal (LLN) per
institutional guidelines, or 55%
- Prior allogeneic bone marrow transplant or double umbilical cord blood
transplantation
- Patients with active hepatitis (B or C)
- Patients with active pneumonitis
- Pregnant women are excluded from this study because olaparib and cediranib are agents
with the potential for teratogenic or abortifacient effects; because there is an
unknown but potential risk for adverse events in nursing infants secondary to
treatment of the mother with olaparib or cediranib, breastfeeding should be
discontinued if the mother is treated with olaparib or cediranib; these potential
risks may also apply to other agents used in this study
- Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral
therapy are ineligible because of the potential for pharmacokinetic interactions with
olaparib and cediranib; in addition, these patients are at increased risk of lethal
infections when treated with marrow-suppressive therapy; appropriate studies will be
undertaken in patients receiving combination antiretroviral therapy when indicated
- Patients must be willing and able to check and record daily blood pressure readings if
receiving cediranib
