- Description
Binimetinib, also known as Mektovi, is a potent is a potent and selective oral mitogen-activated protein kinase 1/2 (MEK 1/2) inhibitor which is combined with Encorafenib 4,8.
On June 27, 2018, the Food and Drug Administration approved the combination of Encorafenib and binimetinib (BRAFTOVI and MEKTOVI, from Array BioPharma Inc.) in combination for patients with unresectable or metastatic melanoma with the BRAF V600E or V600K mutations, as detected by an FDA-approved test 8.

Binimetinib is a MEK inhibitor. MEK is an enzyme that regulates the biosynthesis of the inflammatory cytokines TNF, IL-6 and IL-1. MEK inhibitors interfere with these biosynthetic processes 7. It is a chemotherapeutic agent that has anti-tumor activity 10, 1.
- Mechanism of action
Binimetinib, noncompetitive with ATP, binds to and inhibits the activity of MEK1/2. The inhibition of MEK1/2 prevents the activation of MEK1/2-dependent effector proteins and transcription factors. This process can result in the inhibition of growth factor-mediated cell signaling. This may lead to the inhibition of tumor cell proliferation and an inhibition in the production of various inflammatory cytokines including interleukin-1, -6 and tumor necrosis factor. MEK1/2 are themselves threonine and tyrosine kinases that possess a dual specificity. They subsequently contribute critically to the activation of the RAS/RAF/MEK/ERK pathway and are typically upregulated in a number of different tumor cell types 7.

Following oral administration in a pharmacokinetic study, at least 50% of the binimetinib dose was absorbed with a median time to maximum concentration (Tmax) of 1.6 hours Label.
The administration of a single dose of MEKTOVI 45 mg with a high-fat, high-calorie meal (consisting of approximately 150 calories from protein, 350 calories from carbohydrate, and 500 calories from fat) in healthy subjects had no effect on binimetinib exposure Label.
- Volume of distribution
The geometric mean (CV%) of apparent volume of distribution of binimetinib is 92 L (45%) Label
- Protein binding
Binimetinib is 97% bound to human plasma proteins and the blood-to-plasma ratio is 0.72 Label
- Metabolism
The primary metabolic pathway is glucuronidation with UGT1A1 contributing up to 61% of the binimetinib metabolism. Other pathways of binimetinib metabolism include N-dealkylation, amide hydrolysis, and loss of ethane-diol from the side chain. The active metabolite M3 produced by CYP1A2 and CYP2C19 represents 8.6% of the binimetinib exposure. Following a single oral dose of 45 mg radiolabeled binimetinib, approximately 60% of the circulating radioactivity AUC in plasma was attributable to binimetinib Label.
- Route of elimination
Following a single oral dose of 45 mg radiolabeled binimetinib in healthy subjects, 62% (32% unchanged) of the administered dose was recovered in the feces while 31% (6.5% unchanged) was recovered in the urine Label.
- Half-life
The mean (CV%) terminal half-life (t1/2) of binimetinib is 3.5 hours (28.5%) Label.
- Clearance
20.2 L/h (24%) Label
- Adverse Effects

The most common (≥25%) adverse reactions in patients receiving the combination of this drug with Encorafenib were fatigue, nausea, diarrhea, vomiting, abdominal pain, and arthralgia. Discontinuation of therapy due to adverse reactions occurred in 5% of patients receiving the combination; the most common reasons were hemorrhage and headache 8.
Due to the variety of adverse events associated with this drug, adverse events are categorized by system 12:
Systemic events: Fatigue (31%) 12
Musculoskeletal system: Rhabdomyolysis 12
Ophthalmic events: Retinal hemorrhage, retinal detachment (6%), macular edema, serous retinopathy (20%) 12
Circulatory system: Hypertension, thromboembolic events such as DVT, resulting in pulmonary embolism (5.6%), peripheral edema or periorbital edema (43.5%), hemorrhage (11.2%)12
Pulmonary events: Pneumonitis (1.9%), Pulmonary embolism 12
Cardiovascular system: QT interval prolongation (3.3%), Left ventricular dysfunction (7%) 12
Gastrointestinal system: Hepatotoxicity, diarrhea, nausea, vomiting, stomatitis, dry mouth 12
Dermatologic events: Acneiform dermatitis 9
Based on findings from animal studies and its mechanism of action, MEKTOVI can cause fetal harm when administered to a pregnant woman Label.
