PRTA INVESTORS REMINDER: Lieff Cabraser Reminds Investors of Deadline in Class Action Against Prothena Corporation plc
SAN FRANCISCO--(BUSINESS WIRE)--Jul 5, 2018--The law firm of Lieff Cabraser Heimann & Bernstein, LLP reminds investors of the upcoming deadline to move for appointment as lead plaintiff in the class action litigation has been filed on behalf of investors who purchased or otherwise acquired the publicly traded securities of Prothena Corporation plc (“Prothena” or the “Company”) (NYSE: PRTA) between October 15, 2015 and April 20, 2018, inclusive (the “Class Period”).
If you purchased or otherwise acquired Prothena’s publicly traded securities during the Class Period, you may move the Court for appointment as lead plaintiff by no later than July 16, 2018. A lead plaintiff is a representative party who acts on behalf of other class members in directing the litigation. Your share of any recovery in the actions will not be affected by your decision of whether to seek appointment as lead plaintiff. You may retain Lieff Cabraser, or other attorneys, as your counsel in the actions.
Prothena investors who wish to learn more about the litigation and how to seek appointment as lead plaintiff should click here or contact Sharon M. Lee of Lieff Cabraser toll-free at 1-800-541-7358.
Prothena, incorporated in Ireland and with U.S. headquarters in South San Francisco, California, is a development-stage biotechnology company.
The action alleges that Defendants made false and/or misleading statements and/or failed to disclose the results of an ongoing clinical trial for its principal drug, NEOD001, a monoclonal antibody used to treat a rare, debilitating disease that can lead to organ failure and death. According to the Complaint, throughout the Class Period Prothena cited the “best response” results from the Company’s ongoing clinical study of the NEOD001 antibody as evidence that the drug was effective, while withholding relevant trial data showing that the drug was not effective.
Plaintiff alleges that the truth began to emerge through a series of partial disclosures in 2017 and early 2018, culminating with the April 23, 2018 announcement that Prothena was ending all development of NEOD001 after data from the Phase 2b clinical trial showed that NEOD001 failed to reach either its primary or secondary endpoints, and was substantially less effective than the placebo. On this news, the Company’s stock declined 69%, or $25.34 per share, from the previous closing price of $36.84 on April 20, 2018 to close at $11.50 per share on April 23, 2018, on extremely elevated trading volume.
