Trametinib (Mekinist):
trametinib (Mekinist)
MEK inhibitors block the activity of a cell protein called MEK, a molecule that helps regulate cell growth. MEK is part of a signaling pathway that includes BRAF, another protein. A BRAF mutation signals cells, via MEK, to develop abnormally and divide out of control and grow into a melanoma tumour. MEK inhibitors act on melanomas that have the V600E or V600K mutations in the BRAF protein. These drugs interfere with abnormal BRAF signals to slow or stop the out-of-control cell growth.

Side Effects
Common side effects can include rash, nausea, diarrhea, swelling, and sensitivity to sunlight. Rare but serious side effects can include heart damage, excess bleeding, loss of vision, lung problems, and skin infections. MEK inhibitors are commonly combined with a BRAF inhibitor as a combination therapy. This seems to shrink tumors for longer periods of time than using either type of drug alone. Some side effects (such as the development of other skin cancers) are actually less common with the combination.
Always talk to your doctor, pharmacist or nurse about your side effects so they can help you manage them.

Funded, Dec 1, 2016
BRAF V600 mutation-positive unresectable or metastatic melanoma. Previously untreated or as second line treatment for patients previously treated with first line pembrolizumab or ipilimumab or nivolumab. Only one BRAF/MEK targeted treatment will be funded (daBRAFenib, trametinib, or combination). ECOG 0 to 1. Adequate hematological, hepatic and renal function. If brain metastases are present, patients should be asymptomatic or stable. A BCCA “Compassionate Access Program” request with appropriate clinical information for each patient must be approved prior to treatment.
Funded, Oct 18, 2016
Criteria updated Oct. 30, 2018: Trametinib and/or Dabrafenib for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600 mutation. Not to be used after progression on an alternate BRAF inhibitor and/or MEK inhibitor
Funded, Sep 15, 2014
Monotherapy treatment of patients with BRAF V600 mutation-positive unresectable or metastatic melanoma (either previously untreated or treated with chemotherapy) with an ECOG performance status of 0 or 1; if brain metastases are present, patients should be asymptomatic or stable.
Trametinib is not approved in patients who have progressed on prior BRAF inhibitor therapy.
Funded, Oct 16, 2014
For monotherapy treatment of patients with BRAF V600 mutuation-positive unresectable or metastic melanoma (either previously untreated or treated with chemotherapy) with ECOG performance of 0 or 1. If brain metastases are present, they should be stable. Treatment should continue until disease progression or the development of unacceptable toxicity.
Exclusions: Mekinist is not approved in patients who have progressed on a prior BRAF inhibitor therapy.
Funded, Aug 19, 2014
1st Line Setting Initial requests:
• As monotherapy for the first (1st) line treatment of patients with BRAF V600 mutation-positive unresectable melanoma or metastatic disease.
• If brain metastases are present, they should be stable.
Recommended Dose: 2 mg once daily until disease progression or development of unacceptable toxicity requiring discontinuation of trametinib
Approval duration: 6 months (Patients should have their disease status assessed at least every 3 months) Requests for Mekinist for patients who have initiated another BRAF therapy (i.e. Zelboraf, Tafinlar) and who have not had disease progression will be considered on a case by case basis
2nd Line Setting Initial requests:
• As monotherapy, for the second (2nd) line treatment of patients with BRAF V600 mutation-positive unresectable or metastatic melanoma for patients who have progressed after receiving chemotherapy treatment in the first line setting.
• If brain metastases are present, they should be stable
Recommended Dose: 2 mg once daily until disease progression or development of unacceptable toxicity requiring discontinuation of trametinib
Approval duration: 6 months (Patients should have their disease status assessed at least every 3 months)
Exclusion Criteria:
•BRAF V600 negative, or wild type tumors, or unknown status will not be funded
•Trametinib will not be considered for funding in patients who have progressed on a prior BRAF inhibitor therapy
•Combination therapy with Tafinlar will not be considered for funding
*Under provincial consideration means that the province is reviewing pCODR’s recommendation. This may include the province working with the drug manufacturer to reach an agreement for a drug product that both parties can accept, in particular in cases where the pCODR Expert Review Committee has recommended that the drug be funded only on the condition of cost-effectiveness being improved to an acceptable level. This may occur before or after the pan-Canadian Pricing Alliance negotiations. Please contact the specific provincial drug p

• As monotherapy for the first line treatment of patients with BRAF V600 mutation-positive unresectable or metastatic melanoma with ECOG performance status of 0 or 1. If brain metastases are present, patients should be stable.
• As monotherapy for the second line treatment of patients with BRAF V600 mutation-positive unresectable or metastatic melanoma for patients who have progressed after receiving chemotherapy treatment in the first line setting with ECOG performance status of 0 or 1. If brain metastases are present, patients should be stable.
Clinical Notes:
• Recommended Dose: 2 mg once daily until disease progression or development of unacceptable toxicity requiring discontinuation of trametinib.
• Trametinib will not be reimbursed in patients who have progressed on a prior BRAF therapy.
Claim Notes:
• Initial approval duration: 6 months

Melanoma – Advanced (Unresctable or Metastatic) -For the treatment of patients with BRAF V600 mutation-positive unresectable or metastatic melanoma. Clinical Notes: 1. Patients must have an ECOG performance status of 0 or 1. 2. If brain metastases are present, patients should be asymptomatic or have stable symptoms. 3. Treatment should be discontinued upon disease progression or unacceptable toxicity. Patients must apply for coverage under the High-Cost Drug Program.
