Contra Indications
Precautions
Pneumonitis, including fatal cases, occurred in <1%; interrupt treatment if pneumonitis is suspected; discontinue if pneumonitis is confirmed
Can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals; (see Pregnancy)
Venous thromboembolic events, including pulmonary embolism, occurred in mCRPC patients who were treated with olaparib and androgen deprivation therapy; monitor for signs and symptoms of venous thrombosis and pulmonary embolism and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated
Myelodysplastic syndrome/ acute myeloid leukemia
Myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) occurred in clinical trials
Monitor complete blood cell count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment
Do not initiate treatment until hematological toxicity caused by previous chemotherapy (Grade ≤1) resolves
Pregnancy-Lactation
Pregnancy
Based on findings in animals and mechanism of action, fetal harm may occur when administered to a pregnant woman; there are no available data on use in pregnant women to inform of drug associated risk
Olaparib was teratogenic and caused embryo-fetal toxicity in rats at exposures below those in patients receiving the recommended human dose of 400 mg BID
Contraception
In women of childbearing potential, avoid pregnancy by using effective contraception during treatment and for at least 6 month after receiving the last dose; pregnancy testing is recommended for females of reproductive potential prior to initiating treatment
Based on findings in genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of olaparib
Advise male patients not to donate sperm during therapy and for 3 months following the last dose of olaparib
Lactation
No data are available regarding presence of olaparib in human milk, or on effects on breastfed infant or on milk production; because of potential for serious adverse reactions in breastfed infants from therapy, advise lactating women not to breastfeed during treatment and for 1 month after receiving last dose
Interactions
May reduce efficacy of hormonal contraceptives. May decrease serum concentration with moderate or severe CYP3A4 inducers. May increase serum concentration with moderate or strong CYP3A4 inhibitors. Increased myelosuppression with other antineoplastic agents.
