Attorney Advertising--Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Vivus, Inc. (“Vivus” or the “Company”) (NASDAQ:VVUS - News), concerning whether the company and certain of its officers and directors have violated federal securities laws.

On December 22, 2011, shares of Vivus plunged 15 percent after bad news about an ingredient in its Qnexa obesity drug, is now under review by U.S. regulators. The company tested topiramate, an ingredient in Qnexa, and found that babies born from moms taking the drug had a higher rate of cleft lip and cleft palate. Vivus ran this test, called “Fortress,” for Fetal Outcome Retrospective TopiRamate ExpoSure Study, at the request of regulators. It found a prevalence rate of clefts of 0.29 percent for babies exposed to topiramate while their mothers were pregnant, versus a 0.16 percent rate in babies from moms exposed to the drug before they became pregnant. The Food and Drug Administration refused to approve Qnexa in October 2010 because of concerns about birth defects including cleft lip and palate.
