Tafinlar™ and Mekinist™ approved in Canada for metastatic melanoma 
Melanoma patients with BRAF V600 mutation have two new treatment options in 
their fight against this aggressive and deadly form of cancer 
MISSISSAUGA, ON, July 24, 2013 /CNW/ - Health Canada has approved Tafinlar™ 
(dabrafenib mesylate) and Mekinist™ (trametinib) for patients with 
unresectable (melanoma that cannot be removed by surgery) or metastatic 
(melanoma which has spread to other parts of the body) melanoma. 
Tafinlar™, a BRAF-inhibitor, is indicated as a monotherapy oral treatment 
for unresectable melanoma or metastatic melanoma in adult patients with BRAF 
V600 mutation(1). Mekinist™, a first in class MEK-inhibitor, is also 
indicated as a monotherapy oral treatment for unresectable or metastatic 
melanoma in adult patients with BRAF V600 mutation(2). For both treatments, 
a validated test is required to identify BRAF V600 mutation status. 
"Health Canada's approvals of Tafinlar™ and Mekinist™ represent an 
important step in GSK's ongoing effort to bring new treatment options to 
cancer patients as quickly and efficiently as possible," says Rav Kumar, Vice 
President R&D Operations/Business Development, GSK Canada. "With Tafinlar™ 
and Mekinist™, we hope to make a meaningful difference in the lives of 
patients living with metastatic melanoma, a devastating disease associated 
with very low survival rates and limited treatment options." 
Melanoma is one of the top seven most frequent cancers in Canada (affecting an 
estimated 6,000 people in 2013 and causing 1,027 deaths).(3) In North America, 
one person dies from melanoma every hour and it causes 75 per cent of skin 
cancer-related deaths.(4) If found early and confined to the skin, melanoma 
can usually be removed with surgery, but sometimes melanoma can spread to 
other parts of the body, a process referred to as metastasis. Typically, less 
than five per cent of all new melanoma patients present with metastatic 
"Metastatic melanoma is a devastating diagnosis for Canadian patients and 
their families," says Glenn Crater, Country Medical Director for 
GlaxoSmithKline Inc. "As a result, the approvals of Tafinlar™ and 
Mekinist™ are good news for this patient community and offer two new options 
for doctors and patients fighting this serious and deadly form of skin cancer." 
About Melanoma and Metastatic Melanoma
In Canada, the incidence of melanoma has more than tripled over the last 30 
years and continues to increase.(5) Melanoma is one of the few cancers to 
affect young adults and is the second most common cancer amongst 15-34 year 
olds.(6) Roughly 6,000 (3,300 males and 2,700 females) Canadians will be 
diagnosed with melanoma in 2013, and 1,027 (630 males and 397 females) will 
die from the disease.(7) Survival rates for melanoma are high if it is 
detected early. Historically, in its late stages, the median survival rate has 
been just six months, and at one year only 25 per cent of metastatic melanoma 
patients are still alive.(8)
