Dosing in kidney impairment
Renal Impairment No dosage adjustment is recommended for patients with creatinine clearance (CL cr ) >40 mL/min. The pharmacokinetics and safety of vorasidenib in patients with CL cr ≤40 mL/min or renal impairment requiring dialysis have not been studied [see Clinical Pharmacology ] . For patients with CL cr ≤40 mL/min or who require dialysis, monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended [see Dosage and Administration , Clinical Pharmacology ] .
Dosing in liver impairment
Hepatic Impairment No dosage adjustment is recommended for patients with mild or moderate (Child-Pugh Class A or B) hepatic impairment [see Clinical Pharmacology ]. The pharmacokinetics and safety of vorasidenib in patients with severe hepatic impairment (Child‑Pugh Class C) have not been studied. For patients with severe hepatic impairment, monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended [see Dosage and Administration , Clinical Pharmacology ].
Preparation and administration
Recommended Dosage and Administration Recommended Dosage Adult Patients The recommended dosage of VORANIGO in adult patients is 40 mg orally once daily until disease progression or unacceptable toxicity. Pediatric Patients 12 Years and Older The recommended dosage of VORANIGO in pediatric patients 12 years and older is based on body weight: Patients weighing ≥40 kg: 40 mg orally once daily Patients weighing <40 kg: 20 mg orally once daily Continue treatment with VORANIGO until disease progression or unacceptable toxicity.
Administration Swallow VORANIGO tablets whole with water with or without food [see Clinical Pharmacology ] . Do not split, crush or chew tablets. Missed Dose Take VORANIGO tablets at about the same time each day. If a dose is missed, take the missed dose as soon as possible within 6 hours. If a dose is missed by more than 6 hours, skip the missed dose and take the next dose at the scheduled time.
Vomiting If vomiting occurs after taking a dose, do not take a replacement dose, and take the next dose at the scheduled time on the following day.

Label text (5 paragraphs)
7 DRUG INTERACTIONS CYP1A2 Inhibitors : Avoid concomitant use of strong and moderate CYP1A2 inhibitors. ( 7.1 ) CYP1A2 Inducers : Avoid concomitant use of moderate CYP1A2 inducers and smoking tobacco. ( 7.1 ) Certain CYP3A Substrates : Avoid concomitant use with CYP3A substrates, where a minimal concentration change can reduce efficacy. ( 7.2 ) Hormonal Contraception : If concomitant use cannot be avoided, use with nonhormonal contraception methods. ( 7.2 )
7.1 Effect of Other Drugs on VORANIGO Table 5: Effect of Other Drugs on VORANIGO Strong and Moderate CYP1A2 Inhibitors Clinical Impact Concomitant use of VORANIGO with a strong or moderate CYP1A2 inhibitor may increase vorasidenib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions. Prevention or Management Avoid concomitant use of VORANIGO with strong and moderate CYP1A2 inhibitors. If concomitant use of moderate CYP1A2 inhibitors cannot be avoided, monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended [see Dosage and Administration (2.4) ] .
Moderate CYP1A2 Inducers Clinical Impact Concomitant use of VORANIGO with moderate CYP1A2 inducers and smoking tobacco may decrease vorasidenib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may reduce the anti-tumor activity of VORANIGO. Prevention or Management Avoid concomitant use of VORANIGO with moderate CYP1A2 inducers and smoking tobacco.
7.2 Effect of VORANIGO on Other Drugs Table 6: Effect of VORANIGO on Other Drugs Certain CYP3A Substrates Clinical Impact Concomitant use of VORANIGO with CYP3A substrates may decrease plasma concentrations of CYP3A substrates [see Clinical Pharmacology (12.3) ] . Prevention or Management Avoid concomitant use of VORANIGO with CYP3A substrates, where a minimal concentration change may lead to reduced therapeutic effect. Hormonal Contraception Clinical Impact Concomitant use of VORANIGO may decrease the concentrations of hormonal contraceptives, which may lead to contraception failure and/or an increase in breakthrough bleeding [see Clinical Pharmacology (12.3) ] .
Prevention or Management If concomitant use cannot be avoided, use with nonhormonal contraception methods.

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ] , VORANIGO can cause fetal harm when administered to a pregnant woman. There are no available data on VORANIGO use in pregnant women to inform a drug-associated risk. In animal embryo-fetal development studies, oral administration of vorasidenib to pregnant rats and rabbits during the period of organogenesis caused embryo-fetal toxicity at ≥8 times the human exposure based on the AUC at the highest recommended dose (see Data ) . Advise pregnant women of the potential risk to the 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 In an embryo-fetal development study, vorasidenib was administered to pregnant rats via oral gavage at dose levels of 10, 25, and 75 mg/kg/day during the period of organogenesis (gestation days 6 to 17). Embryo-fetal toxicity (higher incidence of early resorptions, and visceral malformations of kidney and testes) occurred in rats at the maternally toxic dose of 75 mg/kg/day (approximately 170 times the human exposure based on the AUC at the highest recommended dose).
Malformation of heart occurred in a rat at a dose of 25 mg/kg (approximately 97 times the human exposure based on the AUC at the highest recommended dose). Dose-related delayed ossification of bones and short ribs associated with decreased fetal body weights was observed at 10 and 25 mg/kg/day in the absence of maternal toxicity and at 75 mg/kg/day. The dose of 10 mg/kg/day is ≥45 times the human exposure based on the AUC at the highest recommended dose.
In an embryo-fetal development study, oral administration of vorasidenib to pregnant rabbits at dose levels of 2, 6, and 18 mg/kg/day during the period of organogenesis (gestation days 6 to 19) resulted in maternal toxicity at all doses (≥1.5 times the human exposure based on the AUC at the highest recommended dose) and caused higher incidence of late resorptions at 18 mg/kg/day as well as decreased fetal weights and delayed ossification at doses ≥6 mg/kg/day (≥8 times the human exposure based on the AUC at the highest recommended dose).

Not the price at the counterThese are not what a patient pays at the pharmacy counter. They are what pharmacies, health plans, and government buyers pay, before manufacturer rebates. A patient's cost depends on their insurance (copay, coinsurance, or deductible) or the pharmacy's cash price.
