⛔ FDA Black Box Warning
WARNING: OCULAR TOXICITY ELAHERE can cause severe ocular toxicities, including visual impairment, keratopathy, dry eye, photophobia, eye pain, and uveitis [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 )] . Conduct an ophthalmic exam including visual acuity and slit lamp exam prior to initiation of ELAHERE, every other cycle for the first 8 cycles, and as clinically indicated [see Dosage and Administration ( 2.3 )] . Administer prophylactic artificial tears and ophthalmic topical steroids [see Dosage and Administration ( 2.3 ) and Warnings and Precautions ( 5.1 )] . Withhold ELAHERE for ocular toxicities until improvement and resume at the same or reduced dose [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.1 )] . Discontinue ELAHERE for Grade 4 ocular toxicities [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.1 )] .

Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary Based on its mechanism of action, ELAHERE can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (DM4) and affects actively dividing cells [see Clinical Pharmacology ( 12.1 ), Nonclinical Toxicology ( 13.1 )] . Human immunoglobulin G (IgG) is known to cross the placental barrier; therefore, ELAHERE has the potential to be transmitted from the mother to the developing fetus. There are no available human data on ELAHERE use in pregnant women to inform a drug-associated risk. No reproductive or developmental animal toxicity studies were conducted with mirvetuximab soravtansine-gynx. Advise patients of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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. Data Animal Data: No reproductive or developmental animal toxicity studies have been conducted with mirvetuximab soravtansine-gynx. The cytotoxic component of ELAHERE, DM4, disrupts microtubule function, is genotoxic, and can be toxic to actively dividing cells, suggesting it has the potential to cause embryotoxicity and teratogenicity.
