Embryo-Fetal Toxicity and Serious Venous and Arterial Thromboembolism

EMBRYO-FETAL TOXICITY

ZENBEXUS is contraindicated in pregnancy. ZENBEXUS is embryo-fetal toxic in animals and can cause birth defects or embryo-fetal death in humans. In females of reproductive  potential, obtain 2 negative pregnancy tests before starting ZENBEXUS treatment [Contraindications (4), see Warnings and Precautions (5.1) and Use in Specific Populations  (8.1, 8.3)].

Females of reproductive potential must use 2 effective forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after last dose of  ZENBEXUS treatment [see Contraindications (4), Warnings and Precautions (5.1), and Use in Specific Populations (8.1, 8.3)]. 

Because of the risk of embryo-fetal toxicity, ZENBEXUS is only available through a restricted distribution program called ZENBEXUS REMS [see Warnings and Precautions  (5.2)]. 

Information about ZENBEXUS REMS is available at www.ZENBEXUSREMS.com or by calling the REMS Call Center at 1-888-423-5436. 

SERIOUS VENOUS AND ARTERIAL THROMBOEMBOLISM

Increased risk of deep venous thrombosis (DVT), pulmonary embolism (PE), myocardial infarction, and stroke in patients with multiple myeloma receiving ZENBEXUS with daratumumab and hyaluronidase-fihj and dexamethasone. Anti-thrombotic prophylaxis is recommended [see Warnings and Precautions (5.3)].
