Warnings

5 WARNINGS AND PRECAUTIONS • Hypertension: Hypertension including hypertensive crisis has been observed. Blood pressure should be well-controlled prior to initiating INLYTA. Monitor for hypertension and treat as needed. Withhold and then dose reduce INLYTA or permanently discontinue based on severity of hypertension. ( 5.1 ) • Arterial and Venous Thromboembolic Events: Arterial and venous thrombotic events have been observed and can be fatal. Use with caution in patients who are at increased risk for these events. Permanently discontinue INLYTA if an arterial thromboembolic event occurs during treatment. Withhold INLYTA and then resume at same dose or permanently discontinue based on severity of VTE. ( 5.2 , 5.3 ) • Hemorrhage: Hemorrhagic events, including fatal events, have been reported. INLYTA has not been studied in patients with evidence of untreated brain metastasis or recent active gastrointestinal bleeding and should not be used in those patients. Withhold and then dose reduce INLYTA or discontinue based on severity and persistence of hemorrhage. ( 5.4 ) • Cardiac Failure: Cardiac failure has been observed and can be fatal. Monitor for signs or symptoms of cardiac failure throughout treatment with INLYTA. Management of cardiac failure may require dose reduction, dose interruption or permanent discontinuation of INLYTA. ( 5.5 ) • Gastrointestinal Perforation and Fistula Formation: Gastrointestinal perforation and fistula, including death, have occurred. Use with caution in patients at risk for gastrointestinal perforation or fistula. ( 5.6 ) • Hypothyroidism: Hypothyroidism requiring thyroid hormone replacement has been reported. Monitor thyroid function before initiation of, and periodically throughout, treatment with INLYTA. ( 5.7 ) • Impaired Wound Healing: Withhold INLYTA for at least 2 days prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. Resume INLYTA at a reduced dose or discontinue based on severity and persistence of the impaired wound healing. The safety of resumption of INLYTA after resolution of wound healing complications has not been established. ( 5.8 ) • Reversible Posterior Leukoencephalopathy Syndrome (RPLS): RPLS has been observed. Permanently discontinue INLYTA if signs or symptoms of RPLS occur. ( 5.9 ) • Proteinuria: Monitor for proteinuria before initiation of, and periodically throughout, treatment with INLYTA. For moderate to severe proteinuria, withhold and then dose reduce INLYTA. ( 5.10 ) • Hepatotoxicity: Liver enzyme elevation has occurred during treatment with INLYTA as a single agent. Monitor ALT, AST and bilirubin before initiation of, and periodically throughout, treatment with INLYTA. When used in combination with avelumab or pembrolizumab, higher frequencies of Grade 3 and 4 ALT and AST elevation may occur. Consider more frequent monitoring of liver enzymes. Withhold INLYTA and avelumab or pembrolizumab, initiate corticosteroid therapy as needed, and/or permanently discontinue the combination for severe or life-threatening hepatotoxicity. ( 5.11 ) • Use in Patients with Hepatic Impairment: Decrease the starting dose of INLYTA if used in patients with moderate hepatic impairment. INLYTA has not been studied in patients with severe hepatic impairment. ( 2.2 , 5.12 ) • Major adverse cardiovascular events (INLYTA in combination with avelumab): Optimize management of cardiovascular risk factors. Permanently discontinue INLYTA in combination with avelumab for Grade 3–4 events. ( 5.13 ) • Embryo-Fetal Toxicity: INLYTA can cause fetal harm. Advise patients of the potential risk to the fetus and to use effective contraception. ( 5.14 , 8.1 , 8.3 ) 5.1 Hypertension In a controlled clinical study with INLYTA for the treatment of patients with RCC, hypertension was reported in 145/359 patients (40%) receiving INLYTA and 103/355 patients (29%) receiving sorafenib. Grade 3/4 hypertension was observed in 56/359 patients (16%…

Drug interactions

7 DRUG INTERACTIONS • Avoid strong CYP3A4/5 inhibitors. If unavoidable, reduce the INLYTA dose. ( 2.2 , 7.1 ) • Avoid strong CYP3A4/5 inducers. ( 7.2 ) 7.1 CYP3A4/5 Inhibitors Co-administration of ketoconazole, a strong inhibitor of CYP3A4/5, increased the plasma exposure of axitinib in healthy volunteers. Co-administration of INLYTA with strong CYP3A4/5 inhibitors should be avoided. Grapefruit or grapefruit juice may also increase axitinib plasma concentrations and should be avoided. Selection of concomitant medication with no or minimal CYP3A4/5 inhibition potential is recommended. If a strong CYP3A4/5 inhibitor must be co-administered, the INLYTA dose should be reduced [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3) ] . 7.2 CYP3A4/5 Inducers Co-administration of rifampin, a strong inducer of CYP3A4/5, reduced the plasma exposure of axitinib in healthy volunteers. Co-administration of INLYTA with strong CYP3A4/5 inducers (e.g., rifampin, dexamethasone, phenytoin, carbamazepine, rifabutin, rifapentine, phenobarbital, and St. John's wort) should be avoided. Selection of concomitant medication with no or minimal CYP3A4/5 induction potential is recommended [see Dosage and Administration (2.2) , Clinical Pharmacology (12.3) ] . Moderate CYP3A4/5 inducers (e.g., bosentan, efavirenz, etravirine, modafinil, and nafcillin) may also reduce the plasma exposure of axitinib and should be avoided if possible.

Pregnancy

8.1 Pregnancy Risk Summary Based on findings in animal studies and its mechanism of action, INLYTA can cause fetal harm when administered to a pregnant woman. There are no available human data to inform the drug-associated risk. In developmental toxicity studies, axitinib was teratogenic, embryotoxic and fetotoxic in mice at exposures lower than human exposures at the recommended starting dose (see Data ) . Advise females of reproductive potential of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the United States (U.S.) general population of major birth defects is 2%–4% and of miscarriage is 15%–20% of clinically recognized pregnancies. When INLYTA is used in combination with avelumab or pembrolizumab, refer to the full prescribing information of avelumab or pembrolizumab for pregnancy information. Data Animal Data Oral axitinib administered twice daily to female mice prior to mating and through the first week of pregnancy caused an increase in post-implantation loss at all doses tested (≥15 mg/kg/dose, approximately 10 times the systemic exposure (AUC) in patients at the recommended starting dose). In an embryo-fetal developmental toxicity study, pregnant mice received oral doses of 0.15, 0.5 and 1.5 mg/kg/dose axitinib twice daily during the period of organogenesis. Embryo-fetal toxicities observed in the absence of maternal toxicity included malformation (cleft palate) at 1.5 mg/kg/dose (approximately 0.5 times the AUC in patients at the recommended starting dose) and variation in skeletal ossification at ≥0.5 mg/kg/dose (approximately 0.15 times the AUC in patients at the recommended starting dose).
