Trametinib – Uses, Dosage, Side Effects, Interaction Trametinib is a dual-kinase inhibitor that is used in the treatment of advanced malignant melanoma, usually in combination with dabrafenib. Trametinib therapy is associated with transient elevations in serum aminotransferase and alkaline phosphatase levels during therapy but has yet to be linked cases of clinically apparent acute liver injury. Trametinib is an orally bioavailable inhibitor of mitogen-activated protein kinase kinase (MAP2K; MAPK/ERK kinase; MEK) 1 and 2, with potential antineoplastic activity. Upon oral administration, trametinib specifically binds to and inhibits MEK 1 and 2, resulting in an inhibition of growth factor-mediated cell signaling and cellular proliferation in various cancers. MEK 1 and 2, dual specificity serine/threonine and tyrosine kinases often upregulated in various cancer cell types, play a key role in the activation of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth. Trametinib is a pyridopyrimidine that is used (as its dimethyl sulfoxide addition compound) for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations, and who have not received prior BRAF inhibitor treatment. It has a role as an EC 2.7.11.24 (mitogen-activated protein kinase) inhibitor, an antineoplastic agent, an anticoronaviral agent, and a geroprotector. It is a pyridopyrimidine, an organofluorine compound, an organoiodine compound, a member of acetamides, a ring assembly, a member of cyclopropanes and an aromatic amine Trametinib Dimethyl Sulfoxide is a dimethyl sulfoxide (DMSO) solvated form of trametinib, an orally bioavailable inhibitor of mitogen-activated protein kinase kinase (MAP2K; MAPK/ERK kinase; MEK) 1 and 2, with potential antineoplastic activity. Upon oral administration, trametinib specifically binds to and inhibits MEK 1 and 2, resulting in an inhibition of growth factor-mediated cell signaling and cellular proliferation in various cancers. MEK 1 and 2, dual specificity serine/threonine and tyrosine kinases often upregulated in various cancer cell types, play a key role in the activation of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth. Trametinib dimethyl sulfoxide is an addition compound obtained by combining equimolar amounts of trametinib and dimethyl sulfoxide. Used for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations, and who have not received prior BRAF inhibitor treatment. It has a role as an antineoplastic agent and an EC 2.7.11.24 (mitogen-activated protein kinase) inhibitor. It contains dimethyl sulfoxide and trametinib. Trametinib is an orally bioavailable mitogen-activated extracellular signal-regulated kinase 1 (MEK1) and MEK2 inhibitor. It was first approved by the FDA in May 2013 for the treatment of melanoma.[rx] It was later approved by Health Canada on July 18, 2013 [rx] and by the European Commission on June 30, 2014.[rx] Trametinib is currently approved to treat a variety of cancers with BRAF mutations, such as non-small cell lung cancer and thyroid cancer, as monotherapy or in combination with dabrafenib, a BRAF inhibitor, for improved therapeutic efficacy. Originally developed by Japan Tobacco, trametinib was initially investigated for treating inflammation, but further studies for this indication were not pursued.[rx] Mechanism of Action New Window Trametinib is a reversible, allosteric inhibitor of mitogen-activated extracellular signal-regulated kinase 1 _(MEK1)_ and _MEK2_ activation and of_ MEK1_ and _MEK2_ kinase activity. MEK proteins are upstream regulators of the extracellular signal-related kinase (ERK) pathway, which promotes cellular proliferation. Trametinib helps with melanoma with the BRAF V600E or V600K as the mutation results in the constitutive activation of the BRAF pathway which includes MEK1 and MEK2. Trametinib is an anticancer agent which causes apoptosis (or programmed cell death) and inhibits cell proliferation, which are both important in the treatment of malignancies. Trametinib inhibits cell growth of various BRAF V600 mutation-positive tumors in vitro and in vivo. Trametinib is often used in combination with dabrafenib, a BRAF inhibitor. In BRAF-mutant colorectal cancer, induction of EGFR-mediated MAPK pathway re-activation has been identified as a mechanism of intrinsic resistance to BRAF inhibitors.7 Indications New Window Trametinib is indicated as a single agent for the treatment of BRAF-inhibitor treatment-naïve patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations as detected by an FD-approved test. It is used in combination with [dabrafenib] for the: – Treatment of unresectable or metastatic melanoma with BRAF V600E or V600K mutations. – Adjuvant treatment of patients with melanoma with BRAF V600E or V600K mutations, as detected by an FDA-approved test, and involvement of lymph node(s), following complete resection. – Treatment of patients with metastatic non-small cell lung cancer (NSCLC) with BRAF V600E mutation as detected by an FDA-approved test. – Treatment of patients with locally advanced or metastatic anaplastic thyroid cancer (ATC) with BRAF V600E mutation and with no satisfactory locoregional treatment options. Melanoma: Trametinib as monotherapy or in combination with dabrafenib is indicated for the treatment of adult patients with unresectable or metastatic melanoma with a BRAF V600 mutation. Trametinib monotherapy has not demonstrated clinical activity in patients who have progressed on a prior BRAF inhibitor therapy. Adjuvant treatment of melanoma: Trametinib in combination with dabrafenib is indicated for the adjuvant treatment of adult patients with Stage III melanoma with a BRAF V600 mutation, following complete resection. Non-small cell lung cancer (NSCLC): Trametinib in combination with dabrafenib is indicated for the treatment of adult patients with advanced non-small cell lung cancer with a BRAF V600 mutation.

Pregnancy and Lactation AU TGA pregnancy category: D US FDA pregnancy category: Not assigned. Pregnancy Based on its mechanism of action and findings from animal reproduction studies, MEKINIST can cause fetal harm when administered to a pregnant woman. There is insufficient data on pregnant women exposed to MEKINIST to assess the risks. Trametinib was embryotoxic and abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 0.3 times the human exposure at the recommended clinical dose. Advise pregnant women of the potential risk to the fetus. Lactation No information is available on the clinical use of trametinib during breastfeeding. Because trametinib is 97% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is 3.9 to 4.8 days and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during trametinib therapy and for 4 months after the last dose. Why is this medication prescribed? Trametinib is used alone or in combination with dabrafenib (Tafinlar) to treat a certain type of melanoma (a type of skin cancer) that cannot be treated with surgery or that has spread to other parts of the body. It is used in combination with dabrafenib to treat and prevent the return of a certain type of melanoma after surgery to remove it and any affected lymph nodes. Trametinib is also used in combination with dabrafenib to treat a certain type of non-small-cell lung cancer (NSCLC) that has spread to nearby tissues or to other parts of the body. It is used in combination with dabrafenib to treat a certain type of thyroid cancer that has spread to nearby tissues or to other parts of the body, which cannot be treated with other therapies. Trametinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells. How should this medicine be used? Trametinib comes as a tablet to take by mouth. It is usually taken once a day on an empty stomach, at least 1 hour before or 2 hours after a meal. Take trametinib at around the same time every day.
