5 WARNINGS AND PRECAUTIONS Hepatotoxicity : Monitor liver function tests every 2 weeks during the first 2 months of treatment, then monthly for the first 2 years of treatment, and as clinically indicated. Withhold, reduce the dose or discontinue VORANIGO based on severity. ( 2.3 , 5.1 ) Embryo-Fetal Toxicity : VORANIGO can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective nonhormonal contraception. ( 5.2 , 8.1 , 8.3 ) 5.1 Hepatotoxicity VORANIGO can cause hepatic transaminase elevations, which can lead to hepatic failure, hepatic necrosis, and autoimmune hepatitis. In the pooled safety population [see Adverse Reactions (6.1) ] , 58% of patients treated with VORANIGO experienced increased ALT and 44% of patients experienced increased AST. Grade 3 or 4 increased ALT or AST occurred in 9% and 4.8% of patients respectively. Among these patients, 4.1% (10/244) had concurrent Grade 3 to 4 ALT or AST elevations. A total of 34% of patients treated with VORANIGO had increased gamma-glutamyl transferase (GGT), of these 2.2% were Grade 3 or 4. Bilirubin increases occurred in 4.8% of patients treated with VORANIGO, with 0.4% Grade 3 or 4. Nine percent of patients treated with VORANIGO had increased alkaline phosphatase, with 0.9% Grade 3 or 4. Two patients met the laboratory criteria for Hy's Law and had concurrent elevations in ALT or AST >3 times the upper limit of normal and total bilirubin >2 times the upper limit of normal; these events were associated with cases of autoimmune hepatitis and hepatic failure. The median time to first onset of increased ALT or AST was 57 days (range: 1 to 1049). Permanent discontinuation of VORANIGO was required for 2.9% of patients with ALT elevations, 1.6% of AST elevations, and 0.4% of GGT elevations. Dosage reductions of VORANIGO were required for 7% of patients with ALT elevations, 1.2% of AST elevations, and 0.4% of GGT elevations. Dosage interruptions were required in 14% of patients with ALT elevations, 6% of AST elevations, and 1.6% of GGT elevations. Monitor liver laboratory tests (AST, ALT, GGT, total bilirubin and alkaline phosphatase) prior to the start of VORANIGO, every 2 weeks during the first 2 months of treatment, then monthly for the first 2 years of treatment, and as clinically indicated, with more frequent testing in patients who develop transaminase elevations. Reduce the dose, withhold, or permanently discontinue VORANIGO based on severity [see Dosage and Administration (2.3) and Adverse Reactions (6.1) ]. 5.2 Embryo-Fetal Toxicity Based on findings from animal studies, VORANIGO can cause fetal harm when administered to a pregnant woman. In animal embryo-fetal development studies, oral administration of vorasidenib to pregnant rats during the period of organogenesis caused embryo-fetal toxicities at doses ≥45 times the human exposure based on the area under the concentration-time curve (AUC) at the highest recommended dose. Oral administration of vorasidenib to pregnant rabbits during the period of organogenesis resulted in embryo-fetal toxicity at doses ≥8 times the human exposure based on the AUC at the highest recommended dose. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective nonhormonal contraception during treatment with VORANIGO and for 3 months after the last dose, since VORANIGO can render some hormonal contraceptives ineffective [see Drug Interactions (7.2) ] . Advise male patients with female partners of reproductive potential to use effective contraception during treatment with VORANIGO and for 3 months after the last dose [see Use in Specific Populations (8.1 , 8.3) ] .

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. 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. Prevention or Management If concomitant use cannot be avoided, use with nonhormonal contraception methods.

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).
