First-Line Advanced RCC
INLYTA in Combination with Avelumab
The recommended starting dosage of INLYTA is 5 mg orally taken twice daily (12 hours apart) with or without food in combination with avelumab 800 mg administered as an intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity. When INLYTA is used in combination with avelumab, dose escalation of INLYTA above the initial 5 mg dose may be considered at intervals of two weeks or longer. Review the Full Prescribing Information for recommended avelumab dosing information.
INLYTA in Combination with Pembrolizumab
The recommended starting dosage of INLYTA is 5 mg orally twice daily (12 hours apart) with or without food in combination with pembrolizumab 200 mg every 3 weeks or 400 mg every 6 weeks administered as an intravenous infusion over 30 minutes until disease progression or unacceptable toxicity. When INLYTA is used in combination with pembrolizumab, dose escalation of INLYTA above the initial 5 mg dose may be considered at intervals of six weeks or longer. Review the Full Prescribing Information for recommended pembrolizumab dosing information.
Dose Modification Guidelines
Dose increase or reduction is recommended based on individual safety and tolerability.
Recommended INLYTA dosage increases and reductions are provided in Table 1.
Over the course of treatment, patients who tolerate INLYTA for at least two consecutive weeks with no adverse reactions Grade >2 (according to the Common Toxicity Criteria for Adverse Events [CTCAE]), are normotensive, and are not receiving anti-hypertension medication, may have their dose increased.

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)].
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)].
