Category N/ANote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.
What we know about taking Ixazomib while pregnant
Based on its mechanism of action and data from animal reproduction studies, NINLARO can cause fetal harm when administered to a pregnant woman [see CLINICAL PHARMACOLOGY]. There are no human data available regarding the potential effect of NINLARO on pregnancy or development of the embryo or fetus. Ixazomib caused embryo-fetal toxicity in pregnant rats and rabbits at doses resulting in exposures that were slightly higher then those observed in patients receiving the recommended dose . Advise women of the potential risk to a fetus and to avoid becoming pregnant while being treated with NINLARO. 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.
Taking Ixazomib While Breastfeeding
What are recommendations for lactation if you're taking Ixazomib?
No information is available on the clinical use of ixazomib during breastfeeding. Because its half-life is about 9.5 days, it is likely to accumulate in the infant. It is also given in combination with leflunomide and dexamethasone, which may increase the risk to the infant. The manufacturer recommends that breastfeeding be discontinued during ixazomib therapy and for 90 days after the last dose.
