IMBRUVICA ® ( ibrutinib ) capsules
administration of ibrutinib to pregnant rats and rabbits during the period of organogenesis at exposures up to 2-20 times the clinical doses of 420-560 mg daily produced embryofetal toxicity including structural abnormalities ( see Animal Data ). If IMBRUVICA is used during pregnancy or if the patient becomes pregnant while taking IMBRUVICA , the patient should be apprised of the potential hazard to the fetus .
All pregnancies have a background risk of birth defect , loss , or other adverse outcomes . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown . In the U . S . general population , the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4 % and 15-20 %, respectively .
Animal Data : Ibrutinib was administered orally to pregnant rats during the period of organogenesis at doses of 10 , 40 and 80 mg / kg / day . Ibrutinib at a dose of 80 mg / kg / day was associated with visceral malformations ( heart and major vessels ) and increased resorptions and post-implantation loss . The dose of 80 mg / kg / day in rats is approximately 14 times the exposure ( AUC ) in patients with MCL or MZL and 20 times the exposure in patients with CLL / SLL or WM administered the dose of 560 mg daily and 420 mg daily , respectively . Ibrutinib at doses of 40 mg / kg / day or greater was associated with decreased fetal weights . The dose of 40 mg / kg / day in rats is approximately 6 times the exposure ( AUC ) in patients with MCL administered the dose of 560 mg daily .
Ibrutinib was also administered orally to pregnant rabbits during the period of organogenesis at doses of 5 , 15 , and 45 mg / kg / day . Ibrutinib at a dose of 15 mg / kg / day or greater was associated with skeletal variations ( fused sternebrae ) and ibrutinib at a dose of 45 mg / kg / day was associated with increased resorptions and post-implantation loss . The dose of 15 mg / kg / day in rabbits is approximately 2.0 times the exposure ( AUC ) in patients with MCL and 2.8 times the exposure in patients with CLL / SLL or WM administered the dose of 560 and 420 mg daily , respectively .
Lactation : Risk Summary : There is no information regarding the presence of ibrutinib or its metabolites in human milk , the effects on the breastfed infant , or the effects on milk production .
The development and health benefits of breastfeeding should be considered along with the mother ’ s clinical need for IMBRUVICA and any potential adverse effects on the breastfed child from IMBRUVICA or from the underlying maternal condition .
Females and Males of Reproductive Potential : Pregnancy Testing : Verify the pregnancy status of females of reproductive potential prior to initiating IMBRUVICA therapy .
Contraception Females : Advise females of reproductive potential to avoid pregnancy while taking IMBRUVICA and for up to 1 month after ending treatment . If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug , the patient should be informed of the potential hazard to a fetus .
Males : Advise men to avoid fathering a child while receiving IMBRUVICA , and for 1 month following the last dose of IMBRUVICA .
Pediatric Use : The safety and effectiveness of IMBRUVICA in pediatric patients has not been established .
Geriatric Use : Of the 905 patients in clinical studies of IMBRUVICA , 62 % were ≥ 65 years of age , while 21 % were ≥75 years of age . No overall differences in effectiveness were observed between younger and older patients . Anemia ( all grades ) and Grade 3 or higher pneumonia occurred more frequently among older patients treated with IMBRUVICA .
Hepatic Impairment : Avoid use of IMBRUVICA in patients with severe hepatic impairment ( Child-Pugh class C ). The safety of IMBRUVICA has not been evaluated in patients with mild to severe hepatic impairment by Child-Pugh criteria .
Dose modifications of IMBRUVICA are recommended in patients with mild or moderate hepatic impairment ( Child-Pugh class A and B ). Monitor patients for adverse reactions of IMBRUVICA closely [ see Dosage and Administration ( 2.5 ) and Clinical Pharmacology ( 12.3 ) in Full Prescribing Information ].
Plasmapheresis : Management of hyperviscosity in WM patients may include plasmapheresis before and during treatment with IMBRUVICA .
Modifications to IMBRUVICA dosing are not required .
