Can healthy volunteers participate?
No
Key exclusion criteria
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib.
* History of allergic reactions attributed to platinum precluding further use.
* Radiation therapy within 4 weeks of registration
* Use of any other systemic, targeted, immunotherapy, chemotherapy, or investigational agents within 4 weeks of registration
* Previously received a PARP inhibitor
* Other malignancy within the last 2 years with exceptions
* Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection.
* Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
* Concomitant use of known potent CYP3A4 inhibitors
* Concomitant use of known potent CYP3A4 inducers
* Other anti-cancer therapy including immunotherapy, hormonal therapy, biological therapy, other novel agents or investigational agents
* Persistent toxicities (CTCAE v 4.03 grade >2) caused by previous cancer therapy, excluding alopecia
* Patients with myelodysplastic syndrome/acute myeloid leukemia
* Patients with brain metastases
* Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV)
* Patients with known active hepatitis (i.e., hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids
* Pregnant or breastfeeding women
* Receipt of live attenuated vaccine within 30 days prior to enrollment
* Patients with > Grade 2 hearing impairment as per CTCAE v 4.03
* Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into this study.
