⛔ FDA Black Box Warning
WARNING: CYTOKINE RELEASE SYNDROME AND NEUROLOGIC TOXICITY, INCLUDING IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME Cytokine release syndrome (CRS), including serious or life-threatening reactions, can occur in patients receiving LYNOZYFIC. Initiate treatment with LYNOZYFIC step-up dosing to reduce the risk of CRS. Manage CRS, withhold LYNOZYFIC until CRS resolves, and modify the next dose or permanently discontinue based on severity [see Dosage and Administration (2.2 , 2.4 , 2.5) and Warnings and Precautions (5.1) ]. Neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), including serious or life-threatening reactions, can occur in patients receiving LYNOZYFIC. Monitor patients for signs or symptoms of neurologic toxicity, including ICANS during treatment. Manage neurologic toxicity, including ICANS, withhold LYNOZYFIC until neurologic toxicity, including ICANS resolves, and modify the next dose or permanently discontinue based on severity [see Dosage and Administration (2.2 , 2.4 , 2.5) and Warnings and Precautions (5.2) ]. Because of the risk of CRS and neurologic toxicity, including ICANS, LYNOZYFIC is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the LYNOZYFIC REMS [see Warnings and Precautions (5.3) ].

Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary Based on the mechanism of action, LYNOZYFIC may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of LYNOZYFIC in pregnant women to evaluate for a drug associated risk. No animal reproductive or developmental toxicity studies have been conducted with LYNOZYFIC. Linvoseltamab-gcpt causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. In addition, based on the finding of B-cell depletion in non-pregnant animals, linvoseltamab-gcpt can cause B-cell lymphocytopenia in infants exposed to linvoseltamab-gcpt in-utero. Human immunoglobulin (IgG) is known to cross the placenta after the first trimester of pregnancy; therefore, linvoseltamab-gcpt has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus. LYNOZYFIC is associated with hypogammaglobulinemia, therefore, assessment of immunoglobulin levels in newborns of mothers treated with LYNOZYFIC should be considered. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
