( 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 experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells, which are exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation prior to initiating BRAFTOVI [see Indications and Usage (1) , Dosage and Administration (2.1) ] . 5.3 Cardiomyopathy Cardiomyopathy, manifesting as left ventricular dysfunction associated with symptomatic or asymptomatic decreases in ejection fraction, has been reported in patients treated with BRAFTOVI in combination with binimetinib. In COLUMBUS, evidence of cardiomyopathy (decreased in LVEF below the institutional LLN with an absolute decreased in LVEF ≥10% below baseline as detected by echocardiography or MUGA) occurred in 7% of patients receiving BRAFTOVI plus binimetinib. Grade 3 left ventricular dysfunction occurred in 1.6% of patients. The median time to first occurrence of left ventricular dysfunction (any grade) in patients receiving BRAFTOVI in combination with binimetinib was 3.6 months (range 0 to 21 months). Cardiomyopathy resolved in 87% of patients receiving BRAFTOVI plus binimetinib. In PHAROS, evidence of cardiomyopathy (decrease in LVEF below the institutional LLN with an absolute decrease in LVEF ≥10% below baseline as detected by echocardiography or MUGA) occurred in 11% of patients receiving BRAFTOVI in combination with binimetinib. Grade 3 left ventricular dysfunction occurred in 1% of patients. Cardiomyopathy resolved in 82% of patients receiving BRAFTOVI plus binimetinib. Assess ejection fraction by echocardiogram or MUGA scan prior to initiating treatment, one month after initiating treatment, and every 2 to 3 months during treatment. The safety of BRAFTOVI in combination with binimetinib has not been established in patients with baseline ejection fraction that is either below 50% or below the institutional lower limit of normal (LLN). Patients with cardiovascular risk factors should be monitored closely when treated with BRAFTOVI. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction [see Dosage and Administration (2.3) , Adverse Reactions (6.1) ] . 5.4 Hepatotoxicity Hepatotoxicity can occur when BRAFTOVI is administered in combination with binimetinib. In COLUMBUS, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with binimetinib was 6% for alanine aminotransferase (ALT), 2.6% for aspartate aminotransferase (AST), and 0.5% for alkaline phosphatase. In PHAROS, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with binimetinib was 10% for AST, 9% for ALT, and 3.2% for alkaline phosphatase. In BREAKWATER, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6 was 2.6% for alkaline phosphatase, and 1.3% each for ALT and AST. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, the incidence of Grade 3 or 4 increases in liver function laboratory tests was 1.5% each for ALT and AST. Monitor liver laboratory tests before initiation of BRAFTOVI, monthly during treatment, and as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction [see Dosage and Administration (2.3) , Adverse Reactions (6.1) ] . 5.5 Hemorrhage In COLUMBUS, hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with binimetinib; Grade 3 or greater hemorrhage occurred in 3.2% of patients. The most frequent hemorrhagic events were gastrointestinal, including rectal hemorrhage (4.2%), hematochezia (3.1%), and hemorrhoidal hemorrhage (1%). Fatal intracranial hemorrhage in the setting of new or progressive brain metastases occurred in 1.6% of patients. In BEACON CRC, hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with cetuximab; Grade 3 or higher hemorrhage occurred in 1.9% of patients, including fatal gastrointestinal hemorrhage in 0.5% of patients. The most frequent hemorrhagic events were epistaxis (6.9%), hematochezia (2.3%), and rectal hemorrhage (2.3%). In PHAROS, hemorrhage occurred in 12% of patients receiving BRAFTOVI in combination with binimetinib including fatal hemorrhage intracranial (1%); Grade 3 or 4 hemorrhage occurred in 4.1% of patients. The most frequent hemorrhagic events were anal hemorrhage and hemothorax (2% each). In BREAKWATER, hemorrhage occurred in 34 % of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6; Grade 3 or 4 hemorrhage occurred in 3% of patients. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, hemorrhage occurred in 21% of patients. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction [see Dosage and Administration (2.5) , Adverse Reactions (6.1) ] . 5.6 Uveitis Uveitis, including iritis and iridocyclitis, has been reported in patients treated with BRAFTOVI in combination with binimetinib. In COLUMBUS, the incidence of uveitis among patients treated with BRAFTOVI in combination with binimetinib was 4%. In PHAROS, the incidence of uveitis among patients treated with BRAFTOVI in combination with binimetinib was 1%. In BREAKWATER, the incidence of uveitis among patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6 was 0.4%. Assess for visual symptoms at each visit. Perform an ophthalmologic evaluation at regular intervals and for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction [see Dosage and Administration (2.5) , Adverse Reactions (6.1) ] . 5.7 QT Prolongation BRAFTOVI is associated with dose-dependent QTc interval prolongation in some patients [see Clinical Pharmacology (12.2) ] . In COLUMBUS, an increase in QTcF to >500 ms was measured in 0.5% (1/192) of patients who received BRAFTOVI in combination with binimetinib. In PHAROS, an increase in QTcF to >500 ms was measured in 2.1% (2/95) of patients who received BRAFTOVI in combination with binimetinib. In BREAKWATER, an increase of QTcF >500 ms was measured in 4% (9/226) of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, an increase of QTcF >500 ms was measured in 1.5% (1/65) of patients. Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms [see Dosage and Administration (2.5) , Adverse Reactions (6.1) ] . 5.8 Embryo-Fetal Toxicity Based on its mechanism of action, BRAFTOVI can cause fetal harm when administered to a pregnant woman. 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 recommended dose of 450 mg, with no clear findings at lower doses. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use an effective, nonhormonal method of contraception since BRAFTOVI can render hormonal contraceptives ineffective, during treatment and for 2 weeks after the last dose of BRAFTOVI [see Use in Specific Populations (8.1 , 8.3) ] . 5.9 Risks Associated with BRAFTOVI as a Single Agent BRAFTOVI when used as a single agent is associated with an increased risk of certain adverse reactions compared to when BRAFTOVI is used in combination with binimetinib. In COLUMBUS, Grades 3 or 4 dermatologic reactions occurred in 21% of patients treated with BRAFTOVI single agent compared to 2% of patients treated with BRAFTOVI in combination with binimetinib [see Warnings and Precautions (5.1) , Adverse Reactions (6.1) ] . If binimetinib is temporarily interrupted or permanently discontinued, reduce the dose of BRAFTOVI as recommended [see Dosage and Administration (2.5) ] . 5.10 Risks Associated with Combination Treatment BRAFTOVI is indicated for use as part of a regimen in combination with binimetinib, in combination with cetuximab, in combination with cetuximab and mFOLFOX6 or FOLFIRI . Refer to the prescribing information for binimetinib, cetuximab and individual product components of mFOLFOX6 and FOLFIRI for additional risk information.

Contraindications

4 CONTRAINDICATIONS None. None. ( 4 )

Overdose

10 OVERDOSAGE Since encorafenib is 86% bound to plasma proteins, hemodialysis is likely to be ineffective in the treatment of overdose with BRAFTOVI.

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.

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. Table 5 and Table 6 present adverse drug reactions and laboratory abnormalities, respectively, identified in COLUMBUS. The COLUMBUS trial was not designed to demonstrate a statistically significant difference in adverse reaction rates for BRAFTOVI in combination with binimetinib, as compared to vemurafenib, for any specific adverse reaction listed in Table 5.
