( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 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 clinical practice. The safety of INLYTA has been evaluated in combination with avelumab in JAVELIN Renal 101 and pembrolizumab in KEYNOTE-426 for the first-line treatment of patients with advanced RCC [see Clinical Studies (14.1) ] . The data described [see Adverse Reactions (6.1) ] reflect exposure to INLYTA in combination with avelumab in 434 patients and pembrolizumab in 429 patients [see Clinical Studies (14.1) ] . The safety of INLYTA has been evaluated in 715 patients in second-line monotherapy studies, which included 537 patients with advanced RCC. The data described [see Adverse Reactions (6.1) ] reflect exposure to INLYTA in 359 patients with advanced RCC who participated in a randomized clinical study versus sorafenib [see Clinical Studies (14.2) ] . First-Line Advanced RCC INLYTA in Combination with Avelumab The safety of INLYTA in combination with avelumab was evaluated in JAVELIN Renal 101. Patients with autoimmune disease other than type I diabetes mellitus, vitiligo, psoriasis, or thyroid disorders not requiring immunosuppressive treatment were excluded. Patients received INLYTA 5 mg twice daily (N=434) in combination with avelumab 10 mg/kg every 2 weeks administered or sunitinib 50 mg once daily for 4 weeks followed by 2 weeks off (N=439). In the INLYTA plus avelumab arm, 70% were exposed to avelumab for ≥6 months and 29% were exposed for ≥1 year in JAVELIN Renal 101 [see Clinical Studies (14.1) ] . The median age of patients treated with INLYTA in combination with avelumab was 62 years (range: 29 to 83), 38% of patients were 65 years or older, 71% were male, 75% were White, and the Eastern Cooperative Oncology Group (ECOG) performance score was 0 (64%) or 1 (36%). Fatal adverse reactions occurred in 1.8% of patients receiving INLYTA in combination with avelumab. These included sudden cardiac death (1.2%), stroke (0.2%), myocarditis (0.2%), and necrotizing pancreatitis (0.2%). Serious …

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.

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. ( 8.2 ) 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). 8.2 Lactation Risk Summary There are no data on the presence of axitinib in human milk, or its effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions in a breastfed child from INLYTA, advise lactating women not to breastfeed during treatment and for 2 weeks after the last dose. When INLYTA is used in combination with avelumab or pembrolizumab, refer to the full prescribing information of avelumab or pembrolizumab for lactation information. 8.3 Females and Males of Reproductive Potential Based on findings in animal studies, INLYTA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. When INLYTA is used in combination with avelumab or pembrolizumab, refer to the full prescribing information of avelumab or pembrolizumab for contraception information. Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating treatment with INLYTA. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with INLYTA and for 1 week after the last dose. Males Based on findings in animal studies, advise males with female partners of reproductive potential to use effective contraception during treatment and for 1 week after the last dose. Infertility Females and Males Based on findings in animals, INLYTA may impair fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of INLYTA in pediatric patients have not been established. The safety and effectiveness of INLYTA were assessed, but not established, in two open label studies: a dose finding study of INLYTA as a single agent in 17 pediatric patients aged 5 to <17 years with recurrent or refractory solid tumors (ADVL1315, NCT02164838) and a randomized study of INLYTA as a single agent or in combination in 7 pediatric patients aged 7 to <17 years (AREN1721, NCT03595124). No new safety signals were observed with INLYTA in pediatric patients across these studies. Exposure in pediatric patients who received INLYTA at the maximum tolerated …

12.1 Mechanism of Action Axitinib has been shown to inhibit receptor tyrosine kinases including vascular endothelial growth factor receptors (VEGFR)-1, VEGFR-2, and VEGFR-3 at therapeutic plasma concentrations. These receptors are implicated in pathologic angiogenesis, tumor growth, and cancer progression. VEGF-mediated endothelial cell proliferation and survival were inhibited by axitinib in vitro and in mouse models. Axitinib was shown to inhibit tumor growth and phosphorylation of VEGFR-2 in tumor xenograft mouse models.

10 OVERDOSAGE There is no specific treatment for INLYTA overdose. In a controlled clinical study with INLYTA for the treatment of patients with RCC, 1 patient inadvertently received a dose of 20 mg twice daily for 4 days and experienced dizziness (Grade 1). In a clinical dose finding study with INLYTA, subjects who received starting doses of 10 mg twice daily or 20 mg twice daily experienced adverse reactions which included hypertension, seizures associated with hypertension, and fatal hemoptysis. In cases of suspected overdose, INLYTA should be withheld and supportive care instituted.
