• EMRELIS is indicated for the treatment of adult patients with locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC) with high c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining], as determined by an FDA-approved test [see Dosage and Administration ( 2.1 )] , who have received a prior systemic therapy . This indication is approved under accelerated approval based on overall response rate (ORR) and duration of response (DOR) [see Clinical Studies ( 14 )] .ICD-10: C34.90

For intravenous infusion only. ( 2.5 ) The recommended dosage of EMRELIS is 1.9 mg/kg administered intravenously every 2 weeks until disease progression or unacceptable toxicity. ( 2.2 ) Reconstitute and further dilute EMRELIS prior to intravenous infusion. ( 2.5 ) 2.1 Patient Selection Select patients for treatment with EMRELIS based on the presence of high c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining] in patients with non-squamous NSCLC [see Indications and Usage ( 1 ) and Clinical Studies ( 14 )] . Information on FDA-approved tests for the detection of high c-Met protein overexpression is available at: http://www.fda.gov/CompanionDiagnostics. 2.2 Recommended Dosage The recommended dosage of EMRELIS is 1.9 mg/kg (up to a maximum of 190 mg for patients greater than or equal to 100 kg) administered as an intravenous infusion over 30 minutes every 2 weeks until disease progression or unacceptable toxicity. 2.3 Dosage Modifications for Adverse Reactions The recommended dose reductions for adverse reactions are provided in Table 1. Table 1. Recommended Dose Reductions Dose Reduction Recommended Dosage First 1.6 mg/kg every 2 weeks Second 1.3 mg/kg every 2 weeks Third 1 mg/kg every 2 weeks Permanently discontinue EMRELIS in patients who are unable to tolerate 1 mg/kg. The recommended dosage modifications of EMRELIS for adverse reactions are provided in Table 2. Table 2.

Peripheral Neuropathy : Monitor patients for new or worsening peripheral neuropathy. Withhold, reduce the dose, or permanently discontinue EMRELIS based on the severity. ( 5.1 ) I nterstitial Lung Disease (ILD)/ Pneumonitis : Severe, life-threatening or fatal ILD/pneumonitis may occur. Withhold or permanently discontinue EMRELIS based on the severity. ( 5.2 ) Ocular Surface Disorders : Monitor patients for signs or symptoms of ocular surface disorders, including vision changes. Withhold or permanently discontinue EMRELIS based on the severity. ( 5.3 ) Infusion - Related Reactions (IRR) : Monitor patients for IRR. Withhold, reduce the rate of infusion, or permanently discontinue EMRELIS based on the severity. For patients who experience IRR, administer premedications prior to subsequent infusions. ( 5.4 ) Embryo-Fetal Toxicity : Can cause fetal harm. Advise patients about the potential risk to a fetus and to use effective contraception. ( 5.5 ) 5.1 Peripheral Neuropathy EMRELIS can cause peripheral neuropathy, including peripheral sensory neuropathy and peripheral motor neuropathy. In the safety population [see Adverse Reactions ( 6.1 )], peripheral neuropathy occurred in 51% of patients treated with EMRELIS, including Grade 3 in 11%. These adverse reactions included peripheral sensory neuropathy in 45% of patients and peripheral motor neuropathy in 9%. The median time to onset of peripheral neuropathy was 105 days (range: 1 to 472 days). Peripheral neuropathy led to permanent discontinuation of EMRELIS in 13% of patients.

The following clinically significant adverse reactions are described elsewhere in the labeling: Peripheral Neuropathy [see Warnings and Precautions ( 5.1 )] Interstitial Lung Disease (ILD)/Pneumonitis [see Warnings and Precautions ( 5.2 )] Ocular Surface Disorders [see Warnings and Precautions ( 5.3 )] Infusion-Related Reactions (IRR) [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (≥20%) were peripheral neuropathy, fatigue, decreased appetite, and peripheral edema. ( 6.1 ) The most common Grade 3 or 4 laboratory abnormalities (≥2%) were decreased lymphocytes, increased glucose, increased alanine aminotransferase, increased gamma glutamyl transferase, decreased phosphorus, decreased sodium, decreased hemoglobin and decreased calcium. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AbbVie Inc. at 1-800-633-9110 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. LUMINOSITY The safety population described in WARNINGS AND PRECAUTIONS and below reflects exposure to EMRELIS in 168 patients with locally advanced or metastatic EGFR wild-type non-squamous NSCLC with c-Met protein overexpression who received EMRELIS as a single agent administered at 1.9 mg/kg intravenously every 2 weeks in the LUMINOSITY study [see Clinical Studies ( 14 )].

Severe or Moderate Hepatic I mpairment : Avoid use of EMRELIS. ( 8.6 ) Lactation : Advise not to breastfeed. ( 8.2 ) Infertility : May impair fertility. ( 8.3 ) 8.1 Pregnancy Risk Summary Based on the mechanism of action and findings in animals, EMRELIS can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . There are no available human data on EMRELIS use in pregnant women to inform a drug-associated risk. In an animal reproduction study, administration of the small molecule component of EMRELIS, MMAE, to pregnant rats during organogenesis resulted in embryo-fetal mortality and structural abnormalities at exposures similar to the clinical exposure at the recommended dose [see Data ] . Advise patients of the potential risks to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data No embryo-fetal development studies in animals have been performed with telisotuzumab vedotin-tllv.

Metabolism

The exposure parameters of telisotuzumab vedotin-tllv (ADC) and unconjugated MMAE (cytotoxic component of EMRELIS) are summarized in Table 7. The plasma exposure of the ADC and unconjugated MMAE increased proportionally over a dose range of 1.2 to 3.3 mg/kg (0.64 to 1.7 times the approved recommended dose).
