According to the lawsuit, Celladon misstated or failed to disclose adverse information regarding the prospects for MYDICAR—the Company's promising investigational drug for heart failure patients, including that: (1) success in the CUPID1 trial was not indicative of any success in the CUPID2 trial since the CUPID1 trial was extremely small; and (2) the Company's existence was tied to the trial results and defendants were aware of their limitations. When the true details entered the market, the lawsuit claims that investors suffered damages. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than August 31, 2015.
