Qnexa FDA Risks

February 18, 2012 by staff 

Qnexa FDA Risks, Hopes were raised slightly on Friday that U.S. health regulators could approve a weight-loss pill for the first time in 13 years, after government reviewers did not flag fresh safety risks for an experimental obesity drug from Vivus Inc.

Food and Drug Administration staff said in documents posted online that the drug Qnexa did help people lose weight, though they reiterated concerns about the risk of birth defects and heart problems.

The FDA rejected Qnexa in 2010 because of safety problems, and on Friday agency staff still seemed skeptical about the drug’s long-term health effects, especially on the heart.

FDA staff will ask a panel of outside experts next Wednesday to consider whether the benefits of Qnexa for obese patients outweigh its safety risks, or if the company needs to do more studies.

Obesity, a leading cause of diabetes, heart disease and other serious health problems, has reached epidemic proportions in the United States, with about a third of the population affected.

But the FDA has set a high approval bar for weight loss drugs because such a large portion of the general population is likely to want to take them. The agency has not approved a new obesity drug since 1999.

Qnexa is one of three obesity pills up for a second round of consideration from the FDA.
