( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Seagen Inc. at 1-855-4SEAGEN or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in the WARNINGS AND PRECAUTIONS section reflect exposure to TIVDAK in 425 patients with recurrent or metastatic cervical cancer who received at least one dose of TIVDAK at 2 mg/kg intravenously every 3 weeks in innovaTV 301, innovaTV 204, innovaTV 201 (NCT02001623), innovaTV 202 (NCT02552121), innovaTV 203 (NCT03245736), and innovaTV 206 (NCT03913741). The median duration of treatment with TIVDAK was 3.7 months (range: 0.4-40.2). In this pooled safety population, the most common (≥25%) adverse reactions, including laboratory abnormalities, were hemoglobin decreased (45%), peripheral neuropathy (39%), conjunctival adverse reactions (38%), nausea (37%), fatigue (36%), aspartate aminotransferase increased (33%), epistaxis (33%), alopecia (31%), alanine aminotransferase increased (30%), and hemorrhage (28%). The data described in this section reflect exposure to TIVDAK from innovaTV 301 and innovaTV 204. innovaTV 301 The safety of TIVDAK was evaluated in an open-label, randomized study in patients with recurrent or metastatic cervical cancer with disease progression on or after systemic therapy [see Clinical Studies (14.1) ]. A total of 250 patients received TIVDAK 2 mg/kg every 3 weeks until disease progression or unacceptable toxicity. The median duration of treatment with TIVDAK was 3.7 months (range: 0.4-19). Serious adverse reactions occurred in 33% of patients receiving TIVDAK. The most common (≥2%) serious adverse reactions were urinary tract infection (4.8%), small intestinal obstruction (2.4%), sepsis (2%), abdominal pain (2%), and hemorrhage (2%). Fatal adverse reactions occurred in 1.6% of patients who received TIVDAK, including acute kidney injury (0.4%), pneumonia (0.4%), sepsis (0.4%) and Stevens-Johnson syndrome (0.4%). Adverse reactions leading to permanent discontinuation occurred in 15% of patients receiving TIVDAK; the most common (≥3%) adverse reactions leading to permanent discontinuation were peripheral neuropathy (6%) and ocular adverse reactions (6%). Adverse reactions leading to dose interruption occurred in 39% of patients receiving TIVDAK; the most common (≥3%) adverse reactions leading to dose interruption were ocular adverse reactions (16%) and peripheral neuropathy (6%). Adverse reactions leading to dose reduction occurred in 30% of patients receiving TIVDAK; the most common (≥3%) adverse reactions leading to dose reduction were peripheral neuropathy (10%) and ocular adverse reactions (10%). The ocular adverse reactions included conjunctival disorders (4.8%), keratopathy (4%), and dry eye (0.8%). The most common (≥25%) adverse reactions, including laboratory abnormalities, in patients receiving TIVDAK were hemoglobin decreased, peripheral neuropathy, conjunctival adverse reactions, aspartate aminotransferase increased, nausea, alanine aminotransferase increased, fatigue,...Drug Interactions
7 DRUG INTERACTIONS Strong CYP3A4 Inhibitors: Closely monitor for TIVDAK adverse reactions. ( 7.1 ) 7.1 Effects of Other Drugs on TIVDAK Strong CYP3A4 Inhibitors MMAE is a CYP3A4 substrate. Concomitant use of TIVDAK with strong CYP3A4 inhibitors may increase unconjugated MMAE exposure [see Clinical Pharmacology (12.3) ] , which may increase the risk of TIVDAK adverse reactions. Closely monitor patients for adverse reactions of TIVDAK when used concomitantly with strong CYP3A4 inhibitors.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on the mechanism of action and findings in animals, TIVDAK can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available human data on TIVDAK use in pregnant women to inform a drug-associated risk. In an animal reproduction study, administration of the small molecule component of TIVDAK, MMAE, to pregnant rats during organogenesis caused embryo-fetal mortality and structural abnormalities at exposures below the clinical exposure at the recommended dose (see Data ) . Advise patients of the potential risk to a fetus. The 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 embryo-fetal development studies in animals have been performed with tisotumab vedotin-tftv. In an embryo-fetal development study in pregnant rats, administration of two intravenous doses of MMAE, the small molecule component of TIVDAK, on gestational days 6 and 13 caused embryo-fetal mortality and structural abnormalities, including protruding tongue, malrotated limbs, gastroschisis, and agnathia compared to controls at a dose of 0.2 mg/kg (approximately 0.5-fold the human area under the curve [AUC] at the recommended dose).
