Levi & Korsinsky is investigating potential claims on behalf of purchasers of Vanda Pharmaceuticals, Inc. (“Vanda” or the “Company”) (NasdaqGM: VNDA) stock. The investigation stems from concerns regarding the Company’s Phase III trials for the drug Tasimelteon. For more information, click here: http://zlk.9nl.com/vanda-pharmaceuticals-vnda/. On May 31, 2013, Vanda submitted a New Drug Application (“NDA”) for Tasimelteon to the U.S. Food and Drug Administration. Then on June 19, 2013, an article was published on thestreet.com, questioning the efficacy of Vanda’s study, noting that the study not only changed multiple times, but that it replaced the primary endpoint just a month before study results were announced; this replacement primary endpoint was not endorsed by the FDA and had never been used in clinical trials for this type of medication. On the news, shares of Vanda closed at $8.51 per share on June 19, 2013, a drop of more than 20% from the previous day.
