5 WARNINGS AND PRECAUTIONS • New Primary Malignancies, cutaneous and noncutaneous : Can occur. Monitor for malignancies and perform dermatologic evaluations prior to, while on therapy, and following discontinuation of treatment. ( 5.1 ) • Tumor Promotion in BRAF Wild-Type Tumors : Increased cell proliferation can occur with BRAF inhibitors. ( 5.2 ) • Cardiomyopathy : Assess left ventricular ejection fraction (LVEF) before initiating treatment with BRAFTOVI and binimetinib, and after one month of treatment, then every 2 to 3 months thereafter. The safety of BRAFTOVI in combination with binimetinib has not been established in patients with LVEF below 50%. ( 5.3 ) • Hepatotoxicity : Monitor liver function tests before and during treatment with BRAFTOVI and binimetinib and as clinically indicated. ( 5.4 ) • Hemorrhage : Major hemorrhagic events can occur in patients receiving BRAFTOVI and binimetinib. ( 5.5 ) • Uveitis : Perform ophthalmologic evaluation at regular intervals and for any visual disturbances. ( 5.6 ) • QT Prolongation : Monitor electrolytes before and during treatment. Correct electrolyte abnormalities and control for cardiac risk factors for QT prolongation. Withhold BRAFTOVI for QTc of 500 ms or greater. ( 5.7 ) • Embryo-Fetal Toxicity : Can cause fetal harm. Advise females with reproductive potential of potential risk to the fetus and to use effective nonhormonal method of contraception. ( 5.8 , 8.1 , 8.3 ) • Risks Associated with BRAFTOVI as a Single Agent : If binimetinib is temporarily interrupted or permanently discontinued, reduce the dose of BRAFTOVI as recommended. ( 5.9 ) • Risks Associated with Combination Treatment : BRAFTOVI is indicated for use as part of a regimen in combination with binimetinib or cetuximab. ( 5.10 ) 5.1 New Primary Malignancies New primary malignancies, cutaneous and noncutaneous, have been observed in patients treated with BRAF inhibitors and can occur with BRAFTOVI. Cutaneous Malignancies In COLUMBUS, cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 2.6%, and basal cell carcinoma occurred in 1.6% of patients who received BRAFTOVI in combination with binimetinib. Median time to first occurrence of cuSCC/KA was 5.8 months (range 1 to 9 months) [see Adverse Reactions (6.1) ] . For patients who received BRAFTOVI as a single agent, cuSCC/KA was reported in 8%, basal cell carcinoma in 1%, and a new primary melanoma in 5% of patients. In BEACON CRC, cuSCC/KA occurred in 1.4% of patients with CRC, and a new primary melanoma occurred in 1.4% of patients who received BRAFTOVI in combination with cetuximab. In PHAROS, cuSCC and skin papilloma, each occurred in 2% of patients who received BRAFTOVI in combination with binimetinib. In BREAKWATER, the following cutaneous malignancies occurred in patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6: melanocytic nevus in 5.6%, skin papilloma in 3% , basal cell carcinoma in 1.3%, squamous cell carcinoma of skin in 0.9%, keratoacanthoma in 0.4% and malignant melanoma in situ in 0.4%. In patients who received BRAFTOVI in combination with cetuximab and FOLFIRI, skin papilloma occurred in 2.8% and keratoacanthoma in 1.4% of patients. Perform dermatologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Noncutaneous Malignancies Based on its mechanism of action, BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms [see Warnings and Precautions (5.2) ] . Monitor patients receiving BRAFTOVI for signs and symptoms of noncutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive noncutaneous malignancies [see Dosage and Administration (2.5) ] . 5.2 Tumor Promotion in BRAF Wild-Type Tumors In vitro…

Drug interactions

7 DRUG INTERACTIONS • Strong or moderate CYP3A4 inhibitors: Avoid coadministration. If unavoidable, reduce BRAFTOVI dosage. ( 2.6 , 7.1 ) • Strong CYP3A4 inducers: Avoid coadministration. ( 7.1 ) • Sensitive CYP3A4 substrates: Avoid coadministration with CYP3A4 substrates (including hormonal contraceptives) for which a decrease in plasma concentration may lead to reduced efficacy of the substrate. ( 7.2 ) • Transporters: Dose reductions of drugs that are substrates of OATP1B1, OATP1B3, or BCRP may be required when used concomitantly with BRAFTOVI. ( 7.2 , 12.3 ) 7.1 Effect of Other Drugs on BRAFTOVI Strong or Moderate CYP3A4 Inhibitors Coadministration of BRAFTOVI with a strong or moderate CYP3A4 inhibitor increases encorafenib plasma concentrations [see Clinical Pharmacology (12.3) ] and may increase encorafenib adverse reactions. Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors, including grapefruit juice. If coadministration is unavoidable, reduce the BRAFTOVI dose [see Dosage and Administration (2.6) ] . Strong CYP3A4 Inducers Coadministration of BRAFTOVI with a strong CYP3A4 inducer may decrease encorafenib plasma concentrations [see Clinical Pharmacology (12.3) ] and may decrease encorafenib efficacy. Avoid coadministration of BRAFTOVI with strong CYP3A4 inducers. 7.2 Effect of BRAFTOVI on Other Drugs Sensitive CYP3A4 Substrates BRAFTOVI is a strong CYP3A4 inducer at steady-state. Concomitant use of BRAFTOVI may decrease the plasma concentrations of CYP3A4 substrates (including hormonal contraceptives), [see Clinical Pharmacology (12.3) ] , which may reduce the efficacy of these substrates. Avoid the coadministration of BRAFTOVI with CYP3A4 substrates for which a decrease in plasma concentration may lead to reduced efficacy of the substrate. If the coadministration cannot be avoided, see the CYP3A4 substrate product labeling for recommendations. OATP1B1, OATP1B3, or BCRP Substrates Coadministration of BRAFTOVI with OATP1B1, OATP1B3, or BCRP substrates can result in increased concentrations of the substrates, and may increase toxicity of these agents. When used in combination, monitor patients closely for signs and symptoms of increased exposure and consider adjusting the dose of these substrates [see Clinical Pharmacology (12.3) ]. 7.3 Drugs That Prolong the QT Interval BRAFTOVI is associated with dose-dependent QTc interval prolongation [see Warnings and Precautions (5.7) , Clinical Pharmacology (12.2) ] . Avoid coadministration of BRAFTOVI with drugs known to prolong the QT/QTc interval.

Pregnancy

8.1 Pregnancy Risk Summary Based on its mechanism of action, BRAFTOVI can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available clinical data on the use of BRAFTOVI during pregnancy. In animal reproduction studies, encorafenib produced embryo-fetal developmental changes in rats and rabbits and was an abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 26 (in the rat) and 178 (in the rabbit) times the human exposure at the clinical dose of 450 mg, with no clear findings at lower doses (see Data ) . Advise pregnant women and females of reproductive potential of the potential risk to a 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 reproductive toxicity studies, administration of encorafenib to rats during the period of organogenesis resulted in maternal toxicity, decreased fetal weights, and increased incidence of total skeletal variations at a dose of 20 mg/kg/day (approximately 26 times the human exposure based on area under the concentration-time curve [AUC] at the recommended clinical dose of 450 mg once daily). In pregnant rabbits, administration of encorafenib during the period of organogenesis resulted in maternal toxicity, decreased fetal body weights, increased incidence of total skeletal variations and increased post-implantation loss, including total loss of pregnancy at a dose of 75 mg/kg/day (approximately 178 times the human exposure based on AUC at the recommended clinical dose of 450 mg once daily). While formal placental transfer studies have not been performed, encorafenib exposure in the fetal plasma of both rats and rabbits was up to 1.7% and 0.8%, respectively, of maternal exposure.

BRAF V600E or V600K Mutation-Positive Unresectable or Metastatic Melanoma The safety of BRAFTOVI in combination with binimetinib is described in 192 patients with BRAF V600 mutation-positive unresectable or metastatic melanoma who received BRAFTOVI (450 mg once daily) in combination with binimetinib (45 mg twice daily) in a randomized open-label, active-controlled trial (COLUMBUS). The COLUMBUS trial [see Clinical Studies (14.1) ] excluded patients with a history of Gilbert's syndrome, abnormal left ventricular ejection fraction, prolonged QTc (>480 ms), uncontrolled hypertension, and history or current evidence of retinal vein occlusion. The median duration of exposure was 11.8 months for patients treated with BRAFTOVI in combination with binimetinib and 6.2 months for patients treated with vemurafenib. The most common (≥25%) adverse reactions in patients receiving BRAFTOVI in combination with binimetinib were fatigue, nausea, vomiting, abdominal pain, and arthralgia. Adverse reactions leading to dose interruptions of BRAFTOVI occurred in 30% of patients receiving BRAFTOVI in combination with binimetinib; the most common were nausea (7%), vomiting (7%), and pyrexia (4%). Adverse reactions leading to dose reductions of BRAFTOVI occurred in 14% of patients receiving BRAFTOVI in combination with binimetinib; the most common were arthralgia (2%), fatigue (2%), and nausea (2%). Five percent (5%) of patients receiving BRAFTOVI in combination with binimetinib experienced an adverse reaction that resulted in permanent discontinuation of BRAFTOVI; the most common were hemorrhage in 2% and headache in 1% of patients.
