Gastrointestinal stromal tumors (GISTs) predominantly harbor activating mutations in the receptor tyrosine kinase KIT. To genetically dissect in vivo the requirement of different signal transduction pathways emanating from KIT for tumorigenesis, the oncogenic Kit(V558Δ) mutation was combined with point mutations abrogating specific phosphorylation sites on KIT. Compared with single-mutant Kit(V558Δ/+) mice, double-mutant Kit(V558Δ;Y567F/Y567F) knock-in mice lacking the SRC family kinase-binding site on KIT (pY567) exhibited attenuated MAPK signaling and tumor growth...

Mitogen/extracellular signal-regulated kinase (MEK) inhibitors have been tested in clinical trials for treatment of intracranial neoplasms, including glioblastoma (GBM), but efficacy of these drugs has not yet been demonstrated. The blood-brain barrier (BBB) is a major impediment to adequate delivery of drugs into the brain and may thereby also limit the successful implementation of MEK inhibitors against intracranial malignancies. The BBB is equipped with a range of ATP-dependent efflux transport proteins, of which P-gp (ABCB1) and BCRP (ABCG2) are the two most dominant for drug efflux from the brain...

phase II and III clinical trials demonstrated modest anti- tumor activity of Binimetinib (MEK162) - a potent allosteric inhibitor of MEK1 and MEK2- in patients with advanced NRAS mutant melanoma. The analysis of the NEMO study in NRAS mutated melanoma, has shown that pre-treatment with immunotherapy improved the outcome of binimetinib therapy. We discuss this finding in the context of in vitro and in vivo effects of MEK inhibition on immuno-critical pathways and interactions.

Activating NRAS mutations occur in approximately 15-20% of melanomas and are the second most common oncogenic driver mutation in this disease, after BRAF mutations. There is an unmet medical need for new targeted therapy opportunities in metastatic patients whose tumors harbor an NRAS mutation. Binimetinib, a mitogen-activated protein kinase kinase (MEK) inhibitor, has shown clinical activity in this group of patients. Areas covered: The purpose of this paper was to review the safety, activity and efficacy of the MEK inhibitor binimetinib for the treatment of NRAS-mutant melanoma, as well as to discuss future therapeutic perspectives such as multiple pathways, targeted therapy, and combinations with immunotherapy...

Purpose: NRAS mutations in malignant melanoma are associated with aggressive disease requiring rapid antitumor intervention, but there is no approved targeted therapy for this subset of patients. In clinical trials, the MEK inhibitor (MEKi) binimetinib displayed modest antitumor activity, making combinations a requisite. In a previous study, the BRAF inhibitor (BRAFi) vemurafenib was shown to induce endoplasmic reticulum (ER) stress that together with inhibition of the RAF-MEK-ERK (MAPK) pathway amplified its proapoptotic activity in BRAF-mutant melanoma...

New treatments for metastatic melanoma work through distinct mechanisms: enhancing the immune response and blocking cellular proliferation. Agents that enhance the immune response include ipilimumab, pembrolizumb, and nivolumab; agents that block cellular proliferation include vemurafenib, dabrafenib, trametinib, cobimetinib, binimetinib, and selumetinib. The translational impact of laboratory discoveries has revolutionized management of metastatic melanoma and enhanced the prognosis of affected patients.

RATIONALE: BRAF and MEK inhibitors have significantly improved the prognosis of metastatic melanoma, by inhibiting both the mitogen-activated protein kinase (MAP-kinase) pathway. They are associated with infrequent adverse kidney events. Most of these are related to the use of BRAF inhibitors and involve interstitial nephritis with acute tubular necrosis. PATIENT CONCERNS: We report a unique case of glomerulonephritis with renal granulomatous vasculitis in a patient diagnosed with metastatic melanoma treated with BRAF and MEK inhibitors...

Although significant progress has been made in the treatment of unresectable or metastatic melanoma, at least half of all advanced melanoma patients eventually progress and pass away due to their disease. In particular, patients with NRAS-mutated melanoma still face limited therapeutic options, with immunotherapy being the current treatment type of choice. Binimetinib is a selective inhibitor of MEK, a central kinase in the tumor-promoting MAPK pathway. The results of a recent Phase III trial rendered binimetinib the first targeted therapy agent to significantly improve progression-free survival in NRAS-mutated melanoma...

The mitogen-activated protein kinase (MAPK) cascade is an intracellular signaling pathway involved in the regulation of cellular proliferation and the survival of tumor cells. Several different mutations, involving BRAF or NRAS, exert an oncogenic effect by activating the MAPK pathway, resulting in an increase in cellular proliferation. These mutations have become targets for new therapeutic strategies in melanoma and other cancers. Selective MEK inhibitors have the ability to inhibit growth and induce cell death in BRAF- and NRAS-mutant melanoma cell lines...

B7-H3 (CD276) belongs to the B7 family of immunoregulatory proteins and has been implicated in cancer progression and metastasis. In this study, we found that metastatic melanoma cells with knockdown expression of B7-H3 showed modest decrease in proliferation and glycolytic capacity and were more sensitive to dacarbazine (DTIC) chemotherapy and small-molecule inhibitors targeting MAP kinase (MAPK) and AKT/mTOR pathways: vemurafenib (PLX4032; BRAF inhibitor), binimetinib (MEK-162; MEK inhibitor), everolimus (RAD001; mTOR inhibitor), and triciribidine (API-2; AKT inhibitor)...

Targeted therapies for cancers are fast-growing therapies. For instance kinase inhibitors such as BRAF inhibitors (BRAFi) and MEK inhibitors (MEKi) are increasingly used to treat malignant melanoma. The metabolic profile of these drugs can result in great interindividual variability, justifying therapeutic drug monitoring (TDM). We describe a rapid and specific method for quantification of 2 BRAFi (vemurafenib, dabrafenib) and 3 MEKi (cobimetinib, trametinib and binimetinib). Chromatography was performed on a Waters Acquity-UPLC system with CORTECS C18+ column, under a gradient of 10% acetic acid in water/acetonitrile...

BACKGROUND: There are no established therapies specific for NRAS-mutant melanoma despite the emergence of immunotherapy. We aimed to assess the efficacy and safety of the MEK inhibitor binimetinib versus that of dacarbazine in patients with advanced NRAS-mutant melanoma. METHODS: NEMO is an ongoing, randomised, open-label phase 3 study done at 118 hospitals in 26 countries. Patients with advanced, unresectable, American Joint Committee on Cancer stage IIIC or stage IV NRAS-mutant melanoma who were previously untreated or had progressed on or after previous immunotherapy were randomised (2:1) to receive either binimetinib 45 mg orally twice daily or dacarbazine 1000 mg/m(2) intravenously every 3 weeks...

Historically, there were few effective and durable treatments for metastatic melanoma. Recently, mutation based targeted therapies have revolutionized treatment and outcomes for patients with metastatic melanoma. Specifically, inhibitors aimed at BRAF, NRAS, and C-KIT mutations are now commonly used in treatment for patients harboring the specific mutations. Areas covered: A brief review of current BRAF, NRAS, and C-KIT inhibitors provides background for a thorough review of newly developed agents namely binimetinib, a MEK inhibitor, encorafenib a BRAF inhibitor, and masitinib which inhibits C-KIT...

Advanced or recurrent low-grade serous ovarian cancers (LGSC) are resistant to conventional systemic treatments. LGSC carry mutations in RAS or RAF, leading to several clinical trials evaluating MEK inhibitors (MEKi). As LGSC cell lines and xenografts have been difficult to establish, little is known about the efficacy and on-target activity of MEKi treatment in this disease. We compared four different MEKi (trametinib, selumetinib, binimetinib and refametinib) in novel LGSC patient-derived cell lines. Molecular characterization of these cells included copy-number variation and hotspot mutational analysis...

Heterogeneous nuclear ribonucleoprotein K (hnRNP K) is overexpressed in malignant tumors and involved in DNA damage response upon ionizing radiation (IR). Here, we investigate its role in radioresistance of colorectal carcinoma (CRC) and evaluate a pharmacological approach to enhance CRC radiosensitivity via downregulation of hnRNP K. We show that hnRNP K is overexpressed in CRC tissue specimens and upregulated in response to IR in vitro, which occurs faster in KRAS-mutant CRC cells. HnRNP K knockdown impairs cell survival, cell cycle progression and KRAS-dependent radioresistance and increases apoptosis...
