Warnings
WARNING: CAPILLARY LEAK SYNDROME Capillary Leak Syndrome (CLS) which may be life-threatening or fatal, can occur in patients receiving ELZONRIS. Monitor for signs and symptoms of CLS and take actions as recommended [see Warnings and Precautions ( 5.1 )] . WARNING: CAPILLARY LEAK SYNDROME See full prescribing information for complete boxed warning. Capillary Leak Syndrome (CLS), which may be life-threatening or fatal if not properly managed, can occur in patients receiving ELZONRIS. ( 5.1 ) 5 WARNINGS AND PRECAUTIONS Hypersensitivity: Monitor patients for signs/symptoms and treat appropriately. ( 5.2 ) Hepatotoxicity: Monitor ALT and AST. Interrupt ELZONRIS if the transaminases rise to greater than 5 times the upper limit of normal. ( 5.3 ) 5.1 Capillary Leak Syndrome Capillary leak syndrome (CLS), including life-threatening and fatal cases, has been reported among patients treated with ELZONRIS. In patients receiving ELZONRIS in clinical trials, the overall incidence of CLS was 53% (65/122), including Grade 1 or 2 in 43% (52/122) of patients, Grade 3 in 7% (8/122) of patients, Grade 4 in 1% (1/122) of patients, and four fatalities (3%) [see Adverse Reactions (6.1) ] . 4 CONTRAINDICATIONS None. None ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action, ELZONRIS has the potential for adverse effects on embryo-fetal development [see Clinical Pharmacology ( 12.1 )] . There are no available data on ELZONRIS use in pregnant women to inform a drug-associated risk of adverse developmental outcomes. Animal reproduction or developmental toxicity studies have not been conducted with tagraxofusp-erzs. Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
