WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGICAL TOXICITIES including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME Cytokine Release Syndrome (CRS), which may be life-threatening or fatal, occurred in patients receiving BLINCYTO. Interrupt or discontinue BLINCYTO and treat with corticosteroids as recommended [see Dosage and Administration (2.4) , Warnings and Precautions (5.1) ] . Neurological toxicities, including immune effector cell-associated neurotoxicity syndrome (ICANS) which may be severe, life-threatening, or fatal, occurred in patients receiving BLINCYTO.

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Based on its mechanism of action, BLINCYTO may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of BLINCYTO in pregnant women to evaluate for a drug-associated risk. In animal reproduction studies, a murine surrogate molecule administered to pregnant mice crossed the placental barrier (see Data ) . Blinatumomab causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. In addition, based on expression of CD19 on B-cells and the finding of B-cell depletion in non-pregnant animals, blinatumomab can cause B-cell lymphocytopenia in infants exposed to blinatumomab in-utero. Advise pregnant women of the potential risk to a fetus. 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. Clinical Considerations Fetal/Neonatal Adverse Reactions Due to the potential for B-cell lymphocytopenia in infants following exposure to BLINCYTO in utero , the infant's B lymphocytes should be monitored before the initiation of live virus vaccination [see Warnings and Precautions (5.11) ] . Data Animal Data Animal reproduction studies have not been conducted with blinatumomab. In embryo-fetal developmental toxicity studies, a murine surrogate molecule was administered intravenously to pregnant mice during the period of organogenesis. The surrogate molecule crossed the placental barrier and did not cause embryo-fetal toxicity or teratogenicity. The expected depletions of B and T cells were observed in the pregnant mice, but hematological effects were not assessed in fetuses.
