Background

Cobimetinib is an orally active, potent and highly selective small molecule inhibiting mitogen-activated protein kinase kinase 1 (MAP2K1 or MEK1), and central components of the RAS/RAF/MEK/ERK signal transduction pathway. It has been approved in Switzerland and the US, in combination with vemurafenib for the treatment of patients with unresectable or metastatic BRAF V600 mutation-positive melanoma.

Pharmacology

Indication

Cobimetinib is indicated in combination with vemurafenib for the treatment of unresectable or metastatic melanoma with a BRAF V600E or V600K mutation. As a single agent, cobimetinib is also indicated for the treatment of adult patients with histiocytic neoplasms.6

Pharmacodynamics

Cobimetinib is a reversible inhibitor of mitogen-activated protein kinase 1 (MAPK)/extracellular signal-regulated kinase 1 (MEK1) and MEK2. Preclinical studies have demonstrated that this agent is effective in inhibiting the growth of tumor cells bearing a BRAF mutation, which has been found to be associated with many tumor types. A threonine-tyrosine kinase and a key component of the RAS/RAF/MEK/ERK signaling pathway that is frequently activated in human tumors, MEK1 is required for the transmission of growth-promoting signals from numerous receptor tyrosine kinases. Cobimetinib is used in combination with vemurafenib because the clinical benefit of a BRAF inhibitor is limited by intrinsic and acquired resistance. Reactivation of the MAPK pathway is a major contributor to treatment failure in BRAF-mutant melanomas, approximately ~80% of melanoma tumors become BRAF-inhibitor resistant due to reactivation of MAPK signaling. BRAF-inhibitor-resistant tumor cells are sensitive to MEK inhibition, therefore cobimetinib and vemurafenib will result in dual inhibition of BRAF and its downstream target, MEK.1,3,4

Mechanism of action

Cobimetinib is a reversible inhibitor of mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase 1 (MEK1) and MEK2. MEK proteins are upstream regulators of the extracellular signal-related kinase (ERK) pathway, which promotes cellular proliferation. BRAF V600E and K mutations result in constitutive activation of the BRAF pathway which includes MEK1 and MEK2. In mice implanted with tumor cell lines expressing BRAF V600E, cobimetinib inhibited tumor cell growth.6

Cobimetinib and vemurafenib target two different kinases in the RAS/RAF/MEK/ERK pathway. Compared to either drug alone, coadministration of cobimetinib and vemurafenib resulted in increased apoptosis in vitro and reduced tumor growth in mouse implantation models of tumor cell lines harboring BRAF V600E mutations. Cobimetinib also prevented vemurafenib-mediated growth enhancement of a wild-type BRAF tumor cell line in an in vivo mouse implantation model.6

Absorption

Following oral dosing of 60 mg once daily in cancer patients, the median time to achieve peak plasma levels (Tmax) was 2.4 (range:1–24) hours, geometric mean steady-state AUC0-24h was 4340 ng∙h/mL (61% CV) and Cmax was 273 ng/mL (60% CV). The absolute bioavailability of COTELLIC was 46% (90% CI: 40%, 53%) in healthy subjects. A high‐fat meal (comprised of approximately 150 calories from protein, 250 calories from carbohydrate, and 500–600 calories from fat) had no effect on cobimetinib AUC and Cmax after a single 20 mg COTELLIC was administered to healthy subjects.6

Volume of distribution

The estimated apparent volume of distribution was 806 L in cancer patients based on a population PK analysis.6

Protein binding

Cobimetinib is 95% bound to human plasma proteins in vitro, independent of drug concentration.6

Metabolism

Cobimetinib is mainly metabolized via CYP3A oxidation and UGT2B7 glucuronidation with no major metabolites formed.6

Route of elimination

Following oral administration of a single 20 mg radiolabeled cobimetinib dose, 76% of the dose was recovered in the feces (with 6.6% as unchanged drug) and 17.8% of the dose was recovered in the urine (with 1.6% as unchanged drug).6

Half-life

Following oral administration of COTELLIC 60 mg once daily in cancer patients, the mean elimination half-life (t1/2) was 44 (range: 23–70) hours.6

Clearance

Following oral administration of COTELLIC 60 mg once daily in cancer patients, the mean apparent clearance (CL/F) was 13.8 L/h (61% CV).6

Food Interactions
  • Avoid grapefruit products. Grapefruit inhibits the metabolism of cobimetinib through the CYP3A4 pathway and, therefore, may increase serum levels of cobimetinib.
  • Avoid St. John's Wort. This herb induces CYP3A4 metabolism, which may reduce serum levels of cobimetinib.
  • Take with or without food. Cobimetinib bioavailability is unaffected by food.
