treatment no trials the patient may only be seen in follow-up.
- Any previous treatment with PARP inhibitor for this or another cancer, including
olaparib.
- Other malignancy within the last 5 years except: adequately treated non-melanoma skin

family history of long QT syndrome
- Patients receiving any systemic chemotherapy or radiotherapy within 3 weeks prior to

clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir,
saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (eg.
ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout
period prior to starting olaparib is 2 weeks.
- Concomitant use of known strong (eg. phenobarbital, enzalutamide, phenytoin,
rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's Wort ) or
moderate CYP3A inducers (eg. bosentan, efavirenz, modafinil). The required washout
period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3
weeks for other agents.
- Concomitant use of the substrates of CYP3A4, CYP1A2, 2B6, 2C9, 2C19 and P-gp should be
cautioned while on study.
CYP3A4 - hormonal contraceptive, simvastatin, cisapride, cyclosporine, ergot alkaloids,
fentanyl, pimozide, sirolimus, tacrolimus and quetiapine CYP1A2 - duloxetine, melatonin
CYP2B6 - bupropion, efavirenz CYP2C9 - warfarin CYP2C19 - lansoprazole, omeprazole,
S-mephenytoin P-gp - simvastatin, pravastatin, digoxin, dabigatran, colchicine OATP1B1 -

recovered from any effects of any prior major surgery.

disorder, non-malignant systemic disease or active, uncontrolled infection. Examples
include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3
months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal
cord compression, superior vena cava syndrome, extensive interstitial bilateral lung
disease on High Resolution Computed Tomography (HRCT) scan or any psychiatric disorder
that prohibits obtaining informed consent.
- Patients unable to swallow orally administered medication and patients with
gastrointestinal disorders likely to interfere with absorption of the study
medication.
- Immunocompromised patients that according to treating investigator would increase
their risk to protocol treatment, or Patients who are known to be serologically
positive for human immunodeficiency virus (HIV).
- Patients with a known hypersensitivity to olaparib or any of the excipients of the
product.

prevent completion of treatment and would interfere with follow-up.
