Binimetinib

1 INDICATIONS AND USAGE MEKTOVI is a kinase inhibitor indicated: • in combination with encorafenib, for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test. ( 1.1 , 2.1 ) • in combination with encorafenib, for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation, as detected by an FDA-approved test. ( 1.2 , 2.1 ) 1.1 BRAF V600E or V600K Mutation-Positive Unresectable or Metastatic Melanoma MEKTOVI is indicated, in combination with encorafenib, for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test [see Dosage and Administration (2.1) ] .

6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: • New Primary Malignancies [see Warnings and Precautions (5.1) ] • Cardiomyopathy [see Warnings and Precautions (5.2) ] • Venous Thromboembolism [see Warnings and Precautions (5.3) ] • Ocular Toxicities [see Warnings and Precautions (5.4) ] • Interstitial Lung Disease [see Warnings and Precautions (5.5) ] • Hepatotoxicity [see Warnings and Precautions (5.6) ] • Rhabdomyolysis [see Warnings and Precautions (5.7) ] • Hemorrhage [see Warnings and Precautions (5.8) ] • Embryo-Fetal Toxicity [see Warnings and Precautions (5.9) ] • Risks Associated with Combination Treatment [see Warnings and Precautions (5.10) ] Melanoma: Most common adverse reactions (≥25%) for MEKTOVI, in combination with encorafenib,...

8.1 Pregnancy Risk Summary Based on findings from animal reproduction studies and its mechanism of action [see Clinical Pharmacology (12.1) ] , MEKTOVI can cause fetal harm when administered to a pregnant woman. There are no available clinical data on the use of MEKTOVI during pregnancy. In animal reproduction studies, oral administration of binimetinib during the period of organogenesis was embryotoxic and an abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 5 times the human exposure at the clinical dose of 45 mg twice daily (see Data ) .

5 WARNINGS AND PRECAUTIONS • New Primary Malignancies, Cutaneous and Non-cutaneous: Can occur when MEKTOVI is used in combination with encorafenib. Monitor patients for new malignancies prior to initiation of treatment, during treatment, and after discontinuation of treatment. ( 5.1 ) • Cardiomyopathy: Assess left ventricular ejection fraction (LVEF) before initiating treatment, after one month of treatment, then every 2 to 3 months thereafter. The safety of MEKTOVI has not been established in patients with LVEF below 50%. ( 5.2 ) • Venous Thromboembolism: Deep vein thrombosis and pulmonary embolism can occur. ( 5.3 ) • Ocular Toxicities: Serous retinopathy, retinal vein occlusion (RVO) and uveitis have occurred. 4 CONTRAINDICATIONS None. None. ( 4 )
