⛔ FDA Black Box Warning

WARNING: FATAL INFUSION-RELATED REACTIONS, SEVERE MUCOCUTANEOUS REACTIONS, HEPATITIS B VIRUS REACTIVATION and PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY Infusion-Related Reactions Administration of rituximab products can result in serious, including fatal, infusion-related reactions. Deaths within 24 hours of rituximab infusion have occurred. Approximately 80% of fatal infusion-related reactions occurred in association with the first infusion. Monitor patients closely. Discontinue RUXIENCE infusion for severe reactions and provide medical treatment for Grade 3 or 4 infusion-related reactions [see Warnings and Precautions (5.1) , Adverse Reactions (6.1) ] . Severe Mucocutaneous Reactions Severe, including fatal, mucocutaneous reactions can occur in patients receiving rituximab products [see Warnings and Precautions (5.2) ] . Hepatitis B Virus (HBV) Reactivation HBV reactivation can occur in patients treated with rituximab products, in some cases resulting in fulminant hepatitis, hepatic failure, and death. Screen all patients for HBV infection before treatment initiation, and monitor patients during and after treatment with RUXIENCE. Discontinue RUXIENCE and concomitant medications in the event of HBV reactivation [see Warnings and Precautions (5.3) ] . Progressive Multifocal Leukoencephalopathy (PML) Progressive Multifocal Leukoencephalopathy (PML), including fatal PML, can occur in patients receiving rituximab products [see Warnings and Precautions (5.4) , Adverse Reactions (6.3) ] . WARNING: FATAL INFUSION-RELATED REACTIONS, SEVERE MUCOCUTANEOUS REACTIONS, HEPATITIS B VIRUS REACTIVATION and PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY See full prescribing information for complete boxed warning. • Fatal infusion-related reactions within 24 hours of rituximab infusion; approximately 80% of fatal reactions occurred with first infusion. Monitor patients and discontinue RUXIENCE infusion for severe reactions ( 5.1 , 6.1 ). • Severe mucocutaneous reactions, some with fata

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Based on human data, rituximab products can cause adverse developmental outcomes including B-cell lymphocytopenia in infants exposed in-utero (see Clinical Considerations ) . In animal reproduction studies, intravenous administration of rituximab to pregnant cynomolgus monkeys during the period of organogenesis caused lymphoid B-cell depletion in the newborn offspring at doses resulting in 80% of the exposure (based on AUC) of those achieved following a dose of 2 grams in humans. Advise pregnant women of the risk to a fetus. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The background risk of major birth defects and miscarriage for the indicated populations is unknown. The estimated background risk in the U.S. general population of major birth defects is 2%–4% and of miscarriage is 15%–20% of clinically recognized pregnancies. Clinical Considerations Fetal/Neonatal Adverse Reactions Observe newborns and infants for signs of infection and manage accordingly. Data Human Data Postmarketing data indicate that B-cell lymphocytopenia generally lasting less than six months can occur in infants exposed to rituximab in-utero. Rituximab was detected postnatally in the serum of infants exposed in-utero. Animal Data An embryo-fetal developmental toxicity study was performed on pregnant cynomolgus monkeys. Pregnant animals received rituximab via the intravenous route during early gestation (organogenesis period; post coitum Days 20 through 50). Rituximab was administered as loading doses on post coitum (PC) Days 20, 21, and 22, at 15, 37.5, or 75 mg/kg/day, and then weekly on PC Days 29, 36, 43, and 50, at 20, 50, or 100 mg/kg/week. The 100 mg/kg/week dose resulted in 80% of the exposure (based on AUC) of those achieved following a dose of 2 grams in humans. Rituximab crosses the monkey placenta. Exposed offspring did not exhibit any teratogenic effects but did have decreased lymphoid tissue B cel
