Other Adverse Reactions Grade 3 • Reduce dosage by one level. Grade 4 • Withhold until resolution to Grade 2. • Resume at a reduced dose. Table 3 represents additional recommended dosage modifications for adverse reactions when INLYTA is administered in combination with avelumab or pembrolizumab. See the Full Prescribing Information for additional dosage information for avelumab or pembrolizumab including dose modifications for immune-mediated adverse reactions. Table 3: Recommended Dosage Modification for Adverse Reactions for INLYTA in Combination with Avelumab or Pembrolizumab Treatment Adverse Reaction Severity Based on Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Dosage Modifications for INLYTA ALT = alanine aminotransferase, AST = aspartate aminotransferase, ULN = upper limit normal INLYTA in combination with avelumab OR pembrolizumab Liver enzyme elevations Consider corticosteroid therapy ALT or AST at least 3 times ULN but less than 10 times ULN without concurrent total bilirubin at least 2 times ULN • Withhold both INLYTA and avelumab or pembrolizumab until resolution to Grades 0–1 • Consider rechallenge with INLYTA and/or avelumab or pembrolizumab If rechallenging with INLYTA, consider dosage reduction per Table 1. Consider rechallenge with a single drug or sequential rechallenge with both drugs after recovery. ALT or AST increases to more than 3 times ULN with concurrent total bilirubin at least 2 times ULN or ALT or AST at least 10 times ULN • Permanently discontinue both INLYTA and avelumab or pembrolizumab Diarrhea Grade 1–2 • Initiate symptomatic medications. Grade 3 • Interrupt INLYTA and initiate symptomatic medications. If diarrhea is controlled, INLYTA may be resumed at either the same dose or reduced by 1 dose level. Grade 4 • Withhold INLYTA until resolution to Grade <2, then restart INLYTA dose reduced by 1 dose level INLYTA in combination with avelumab Major Adverse Cardiovascular Events (MACE) Grade 3 or 4 • Permanently discontinue 2.3 Dosage Modification for Drug Interactions Strong CYP3A4/5 Inhibitors The concomitant use of strong CYP3A4/5 inhibitors should be avoided (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, and voriconazole). Selection of an alternate concomitant medication with no or minimal CYP3A4/5 inhibition potential is recommended. Although INLYTA dose adjustment has not been studied in patients receiving strong CYP3A4/5 inhibitors, if a strong CYP3A4/5 inhibitor must be co-administered, a dose decrease of INLYTA by approximately half is recommended, as this dose reduction is predicted to adjust the axitinib area under the plasma concentration vs time curve (AUC) to the range observed without inhibitors. The subsequent doses can be increased or decreased based on individual safety and tolerability. If co-administration of the strong inhibitor is discontinued, the INLYTA dose should be returned (after 3 – 5 half-lives of the inhibitor) to that used prior to initiation of the strong CYP3A4/5 inhibitor [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ]. 2.4 Dosage Modification for Hepatic Impairment No starting dose adjustment is required when administering INLYTA to patients with mild hepatic impairment (Child-Pugh class A). Based on the pharmacokinetic data, the INLYTA starting dose should be reduced by approximately half in patients with baseline moderate hepatic impairment (Child-Pugh class B). The subsequent doses can be increased or decreased based on individual safety and tolerability. INLYTA has not been studied in patients with severe hepatic impairment (Child-Pugh class C) [see Warnings and Precautions (5.12) , Use in Specific Populations (8.6) , and Clinical Pharmacology (12.3) ].

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Vascular disorders: arterial (including aortic), aneurysms, dissections, and rupture.

12.3 Pharmacokinetics The population pharmacokinetic analysis pooled data from 17 trials in healthy subjects and patients with cancer. A two-compartment disposition model with first-order absorption and lag-time adequately describes the axitinib concentration-time profile. Absorption and Distribution Following single oral 5-mg dose administration, the median Tmax ranged from 2.5 to 4.1 hours. Based on the plasma half-life, steady state is expected within 2 to 3 days of dosing. Dosing of axitinib at 5 mg twice daily resulted in approximately 1.4-fold accumulation compared to administration of a single dose. At steady state, axitinib exhibits approximately linear pharmacokinetics within the 1-mg to 20-mg dose range. The mean absolute bioavailability of axitinib after an oral 5 mg dose is 58%. Compared to overnight fasting, administration of INLYTA with a moderate fat meal resulted in 10% lower AUC and a high fat, high-calorie meal resulted in 19% higher AUC. INLYTA can be administered with or without food [see Dosage and Administration (2.1) ] . Axitinib is highly bound (>99%) to human plasma proteins with preferential binding to albumin and moderate binding to α1-acid glycoprotein. In patients with advanced RCC (n=20), at the 5 mg twice daily dose in the fed state, the geometric mean (CV%) C max and AUC 0–24 were 27.8 (79%) ng/mL and 265 (77%) ng.h/mL, respectively. The geometric mean (CV%) clearance and apparent volume of distribution were 38 (80%) L/h and 160 (105%) L, respectively. Metabolism and Elimination The plasma half-life of INLYTA ranges from 2.5 to 6.1 hours. Axitinib is metabolized primarily in the liver by CYP3A4/5 and to a lesser extent by CYP1A2, CYP2C19, and UGT1A1. Following oral administration of a 5-mg radioactive dose of axitinib, approximately 41% of the radioactivity was recovered in feces and approximately 23% was recovered in urine. Unchanged axitinib, accounting for 12% of the dose, was the major component identified in feces. Unchanged axitinib was not detected in urine; the carboxylic acid and sulfoxide metabolites accounted for the majority of radioactivity in urine. In plasma, the N-glucuronide metabolite represented the predominant radioactive component (50% of circulating radioactivity) and unchanged axitinib and the sulfoxide metabolite each accounted for approximately 20% of the circulating radioactivity. The sulfoxide and N-glucuronide metabolites show approximately ≥400-fold less in vitro potency against VEGFR-2 compared to axitinib. Drug-Drug Interactions Effects of Other Drugs on INLYTA Axitinib is metabolized primarily in the liver by CYP3A4/5. Additionally, the aqueous solubility of axitinib is pH dependent, with higher pH resulting in lower solubility. The effects of a strong CYP3A4/5 inhibitor, a strong CYP3A4/5 inducer, and an antacid on the pharmacokinetics of axitinib are presented in Figure 1 [see Dosage and Administration (2.2) and Drug Interactions (7.1 , 7.2) ] . Figure 1. Impact of Co-administered Drugs and Hepatic Impairment on Axitinib Pharmacokinetics Figure 1 Effects of INLYTA on Other Drugs In vitro studies demonstrated that axitinib has the potential to inhibit CYP1A2 and CYP2C8. However, co-administration of axitinib with paclitaxel, a CYP2C8 substrate, did not increase plasma concentrations of paclitaxel in patients. In vitro studies indicated that axitinib does not inhibit CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4/5, or UGT1A1 at therapeutic plasma concentrations. In vitro studies in human hepatocytes indicated that axitinib does not induce CYP1A1, CYP1A2, or CYP3A4/5. Axitinib is an inhibitor of the efflux transporter P-glycoprotein (P-gp) in vitro. However, INLYTA is not expected to inhibit P-gp at therapeutic plasma concentrations. Specific Populations Patients with Hepatic Impairment The effects of hepatic impairment on the pharmacokinetics of axitinib are presented in Figure 1 [see Dosage and Administration (2.2) , Warnings and Precautions (5.12) , Use in Specific Populations (8.6) ] . Patients with Renal Impairment Population pharmacokinetic analysis (based on pre-existing renal function) was carried out in 590 healthy volunteers and patients, including five with severe renal impairment (15 mL/min ≤CLcr <29 mL/min), 64 with moderate renal impairment (30 mL/min ≤CLcr <59 mL/min), and 139 with mild renal impairment (60 mL/min ≤CLcr <89 mL/min). Mild to severe renal impairment did not have meaningful effects on the pharmacokinetics of axitinib. Data from only one patient with end-stage renal disease are available [see Use in Specific Populations (8.7) ] . Other Intrinsic Factors Population pharmacokinetic analyses indicate that there are no clinically relevant effects of age, gender, race, body weight, body surface area, UGT1A1 genotype, or CYP2C19 genotype on the clearance of axitinib. INLYTA in Combination with Avelumab When INLYTA 5 mg was administered in combination with avelumab 10 mg/kg, the respective exposures of INLYTA and avelumab were comparable to the single agents. There was no evidence to suggest a clinically relevant change of avelumab clearance over time in patients with advanced RCC. INLYTA in Combination with Pembrolizumab When INLYTA 5 mg was administered in combination with pembrolizumab 200 mg, the respective exposures of INLYTA and pembrolizumab were comparable to the single agents.
