Qnexa

Qnexa [kyoo-nek-suh] is an investigational drug candidate being developed to address weight loss, type 2 diabetes and obstructive sleep apnea. Qnexa is a once-a-day, proprietary, oral, controlled-release formulation of low-dose phentermine and topiramate, which is designed to decrease appetite and increase satiety (the sense of feeling full), the two main mechanisms that impact eating behavior. In Phase 2 and Phase 3 clinical data to date, patients taking Qnexa have demonstrated statistically significant weight loss, better glycemic control, and improvement in cardiovascular risk factors when they used the drug in combination with a diet and lifestyle modification program.

On February 22, 2012, the United States Food and Drug Administration Endocrinologic and Metabolic Drugs Advisory Committee recommended, in a 20-to-2 vote, that Qnexa be granted marketing approval for the treatment of obesity in adults. The Prescription Drug User Fee Act target date for Qnexa is July 17, 2012.
