Update on Drugs and Drug News: March-April 2014


Name/Company Approval Dates and Comments

Trametinib + Dabrafenib
Mekinist® + Tafinlar®
GlaxoSmithKline plc

The US FDA granted accelerated approval in January 2014 to trametinib in combination with dabrafenib for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations. Approval of the combination therapy is based on the demonstration of response rate and median duration of response in a multicenter, open-label, randomized, active-controlled, dose-ranging phase I/II trial, which compared combination trametinib and dabrafenib to dabrafenib monotherapy. The overall response rate was 76% (95% confidence interval [CI]; 62, 87) with combination therapy compared to 54% (95% CI; 40, 67) with dabrafenib alone. The median duration of response was 10.5 months (95% CI; 7, 15) with combination therapy compared to 5.6 months (95% CI; 5, 7) with monotherapy. Improvement in diseaserelated symptoms or overall survival has not yet been shown. The accelerated approval is contingent on the results of the ongoing phase III trial evaluating the clinical benefit of this dual combination treatment.

Drug News

In January 2014, the FDA issued a warning to consumers and healthcare professionals that flammable over-the-counter wart removers have started fires, resulting in injuries to at least 10 people, who suffered singed hair, blisters, burns or skin redness. Since 2009, the FDA has received 14 reports about some cryogenic wart removers. In several cases, combustion occurred when the products (a mixture of liquid dimethyl ether and propane) were used near a candle. In 3 of the reports to the FDA, there was a candle nearby, but no ignition source was identified in the other 11 reports. Labeling for these products clearly states that they are flammable and should be kept away from fire, flame, heat sources, and cigarettes. In the incidents reported to the FDA, the wart remover dispenser generally caught fire when the mixture was being released.
