MOUNTAIN VIEW, Calif., Dec. 14, 2010 /PRNewswire/ -- VIVUS, Inc. today announced that the company, as part of its continuing effort to secure regulatory approval for Qnexa in the U.S., submitted a briefing document to the Food and Drug Administration (FDA) designed to address items in the FDA's Complete Response Letter (CRL), issued on October 28, 2010. The company also announced that the Endocrine and Metabolic Division of the FDA has granted VIVUS a meeting in the second half of January 2011 to discuss the content of the proposed resubmission.

VIVUS is pursuing regulatory approval to market Qnexa (phentermine/topiramate) Controlled Release Capsules in the U.S. for the treatment of obesity, including weight loss and maintenance of weight loss, in patients who are obese or overweight with co-morbidities such as hypertension, type 2 diabetes, dyslipidemia or central adiposity.

"Submission of our briefing document and confirmation of our meeting with the FDA indicate the continued progress VIVUS is making in seeking U.S. approval of Qnexa for the treatment of obesity," said Leland Wilson, chief executive officer of VIVUS. "We are confident in the data analyses we have compiled in the briefing document, and we look forward to our meeting with the FDA."

About Qnexa Controlled Release Capsules

Qnexa [kyoo-nek-suh] is an investigational drug 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 together decrease appetite and increase satiety (the sense of feeling full), the two main mechanisms that impact eating behavior. In phase 2 and 3 clinical data to date, patients taking Qnexa have demonstrated statistically significant weight loss, glycemic control and improvement in cardiovascular risk factors, when used in combination with a diet and lifestyle modification program.

About Obesity

Obesity is a chronic condition defined by having excess body fat. Obesity significantly increases the risk of developing many different diseases and health conditions, including type 2 diabetes, hypertension, metabolic syndrome, cardiovascular disease, some cancers and osteoarthritis. According to a report in The Lancet in 2009, morbid obesity shortens life expectancy by approximately 10 years, and moderate obesity shortens it by approximately 3 years.

Approximately one-third of American adults (more than 72 million people) are obese, and many more are overweight with co-morbidities. Beyond its impact on health, obesity accounts for 9.1% of US annual health care spending – nearly $150 billion.
