Dabrafenib (Tafinlar) plus trametinib (Mekinist) Targeted Therpies
Dabrafenib (Tafinlar) + trametinib (Mekinist)
Dabrafenib (Tafinlar) plus trametinib (Mekinist) is a prescription medicine, the drugs are administered as pills.
This is a first-line treatment for patients with BRAF V600 mutation-positive unresectable stage IIIC or IV melanoma or metastatic melanoma. The combination of dabrafenib and trametinib blocks the signaling pathway of the abnormal BRAF molecules. This action slows or stops the out-of-control cell growth:
Dabrafenib targets the V600E-mutated BRAF molecule to block its signaling.
Trametinib targets MEK to block signaling from the V600E- or V600K-mutated BRAF molecule via the MEK molecule.
Side effects can include rash, nausea, diarrhea, swelling, fatigue and extreme sensitivity to sunlight (UV radiation). Rare but serious side effects can include heart damage, excess bleeding, loss of vision, lung problems and skin infections. Some side effects (such as the development of other skin cancers) are actually less common with the combination therapy.
Always talk to your doctor, pharmacist or nurse about your side effects so they can help you manage them.

Please note: This information is not meant to act as a treatment decision aid, but rather to provide general information about which metastatic melanoma or skin cancer treatments are covered by provincial health care plans in Canada. It is current to the date indicated and may not be currently accurate due to the changing landscape of coverage in Canada. If you have private insurance coverage, you may have access to therapies not covered by the provincial plans in your province. All information obtained about specific treatments should be further discussed with your physician.
