This phase II trial studies how well radiation therapy with or without olaparib works in
treating patients with inflammatory breast cancer. Radiation therapy uses high energy x-rays
to kill tumor cells and shrink tumors. Olaparib is an inhibitor of PARP, an enzyme that helps
repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep
cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a
type of targeted therapy. It is not yet known whether radiation therapy with or without
olaparib may work better in treating patients with inflammatory breast cancer.
- Patients must have inflammatory breast cancer without distant metastases. All
biomarker subtype groups (estrogen receptor [ER], progesterone receptor [PR], HER2)
are eligible. Inflammatory disease will be defined per American Joint Committee on
Cancer (AJCC) 8th edition with documentation by history/exam and pathology at the time
- All patients must have completed neoadjuvant chemotherapy prior to mastectomy. The
chemotherapy regimen is at the discretion of the treating physician but it is
recommended that it include at least 4 cycles of anthracycline and/or taxane-based
therapy (plus targeted therapy for patients with HER2+ disease). Response to
chemotherapy is not a criterion for eligibility (both complete responders and those
with residual disease are eligible). Please note that although pathologic complete
response (pCR) is not required or excluded, pCR status must be determined post-surgery
prior to randomization.
- All patients must have undergone modified radical mastectomy (with negative margins on
ink) with pathologic nodal evaluation (from level I and II axillary lymph node
dissection [ALND]) at least 3 weeks and no more than 12 weeks prior to randomization,
unless they receive additional chemotherapy after mastectomy. Patients must not have
gross residual tumor or positive microscopic margins after mastectomy.
- Additional adjuvant chemotherapy after surgery is allowed at the discretion of the
treating physician, either completed prior to randomization or planned for after
completion of protocol treatment. If adjuvant chemotherapy is administered after
mastectomy, the patient must be randomized at least 3 weeks but no more than 12 weeks
after the last dose of adjuvant chemotherapy.
- Patients must not have a history of radiation therapy to the ipsilateral chest wall
and/or regional nodes. Prior radiation therapy to other body sites is allowed.
- Patients must not be planning to receive any other investigational agents during
radiation therapy. Prior therapy, including prior treatment with olaparib or other
PARP inhibitor, is allowed.
- Patients must not have a known hypersensitivity to olaparib or any of the excipients
of the product.
- Patients must not have unresolved or unstable grade 2 or greater toxicity (with the
exception of alopecia) from prior administration of another investigational drug
and/or prior anti-cancer treatment.
- Patients must not be planning to receive strong or moderate CYP3A inhibitors or
inducers while on olaparib treatment. Patients receiving strong or moderate CYP3A
inhibitors must agree to discontinue use at least 2 weeks prior to receiving olaparib.
Patients receiving strong or moderate CYP3A inducers must agree to discontinue use at
least 5 weeks prior to receiving olaparib.
- Patients must not be planning to receive live virus or live bacterial vaccines while
receiving olaparib and during the 30 day follow up period
- Patients must not be planning to receive any additional anti-cancer therapy
(chemotherapy, endocrine therapy, immunotherapy, biological therapy or other novel
agent) while receiving radiotherapy with or without study medication. If a patient is
receiving concurrent anti-HER2 targeted therapies, they must not take these
medications during the period of radiotherapy (with or without study drug) while
enrolled on the study.
- Patients must be >= 18 years of age
- Patients must have Zubrod performance status 0-2.
- Absolute neutrophil count (ANC) >= 1000/mm^3 (within 28 days prior to registration)
- Platelet count >= 100,000/mm^3 (within 28 days prior to registration)
- Hemoglobin >= 9.0 g/dL (after transfusion if required and within 28 days prior to
- Patients must have adequate renal function as evidenced by calculated creatinine
clearance >= 51 mL/min by Cockcroft-Gault equation, within 28 days prior to
- Total bilirubin =< 1.5 x upper limit of normal (ULN) (within 28 days prior to
- Patients with documented Gilbert's disease may have bilirubin up to 2.5 mg/dL
- Serum glutamic-oxaloacetic transaminase (SGOT) =< 2.5 x ULN (within 28 days prior to
- Serum glutamate pyruvate transaminase (SGPT) =< 2.5 x ULN (within 28 days prior to
- Alkaline phosphatase =< 2.5 x ULN (within 28 days prior to registration)
- Patients must not have a history of other prior malignancy except for the following:
adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer,
adequately treated stage I or II cancer from which the patient is currently in
complete remission, or any other cancer from which the patient has been disease free
for five years
- Female patients must be postmenopausal or have a negative urine or serum pregnancy
test within 14 days prior to registration. Female patients of childbearing potential
(and male patients with female partners who are of childbearing potential or pregnant)
who are sexually active, must agree to the use of two highly effective forms of
contraception during protocol treatment and for 6 months following the last dose of
olaparib. Note: The efficacy of hormonal contraceptives may be reduced if
co-administered with olaparib. Male patients must agree not to donate sperm during
protocol treatment and for 6 months after the last dose of olaparib.
- Patients who are breastfeeding must agree to discontinue breastfeeding before
receiving olaparib due to potential risk for adverse events in nursing infants
secondary to treatment of the mother with olaparib.
- Patients must not have active uncontrolled infection, symptomatic congestive heart
failure, unstable angina pectoris or cardiac arrhythmia.
- Patients must be able to swallow and retain oral medications and have no known
gastrointestinal disorders likely to interfere with absorption of the study
- Patients must not have a history of a resting electrocardiography (ECG) indicating
uncontrolled, potentially reversible cardiac conditions (such as unstable ischemia,
uncontrolled symptomatic arrhythmia, congestive heart failure, Fridericia's formula
corrected QT interval [QTcF] prolongation > 500 ms, electrolyte disturbances) or
congenital long QCYP3T syndrome.
- Patients must not have myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or
with features suggestive of MDS/AML.
- Patient must not have had major surgery within 2 weeks of starting study treatments
and patients must have recovered from any effects of any major surgery.

bilateral lung disease on high resolution computed tomography (HRCT) scan.

- Note: Germline and somatic BRCA status (genetic testing) are planned for future
correlative evaluation, in order to examine treatment and circulating tumor
deoxyribonucleic acid (ctDNA) response as stratified by BRCA 1/2 mutational
status. Since this is future planned correlative research, any mutational status
results would not be returned to the patient or the treating physician. There is
no Clinical Laboratory Improvement Act (CLIA)-certified clinical genetic testing
being performed for patients as part of the S1706 study. A forthcoming revision
or separate corelative sciences proposal would be submitted to and approved by
National Cancer Institute (NCI) prior to conduct of any planned future
translational medicine objectives.
