The Klein Law Firm Reminds Investors of a Class Action Commenced on Behalf of Prothena Corporation Shareholders and a Lead Plaintiff Deadline of July 16, 2018 (PRTA)
Jun. 13, 2018
NEW YORK--(BUSINESS WIRE)--Jun 13, 2018--The Klein Law Firm announces that a class action complaint has been filed on behalf of shareholders of Prothena Corporation (NASDAQ: PRTA) who purchased shares between October 15, 2015 and April 20, 2018. The action, which was filed in the United States District Court for the Northern District of California, alleges that the Company violated federal securities laws.
In particular, the complaint alleges that throughout the Class Period, defendants made materially false and/or misleading statements and/or failed to disclose that (1) relevant trial data showed that Prothena’s antibody NEOD001, designed to treat amyloid light chain amyloidosis (“AL amyloidosis”), was not an effective treatment; (2) the Company made misleading comparisons of NEOD001’s “best response” rates against certain prior studies; and (3) the Company touted Prothena’s ongoing Phase 1/2 study of NEOD001 as providing a strong basis for late-stage Phase 2b and Phase 3 studies of NEOD001, even though the full Phase 1/2 study data demonstrated that NEOD001 was not an effective treatment. On October 15, 2015, Prothena announced its late-stage Phase 2b “PRONTO” study and expansion of its Phase 1/2 clinical trial for the antibody NEOD001. On April 23, 2018, Prothena announced it was ending development of NEOD001 after its Phase 2b PRONTO trial failed to reach either its primary or secondary endpoints. Following this news, shares of Prothena fell from a close of $36.84 on April 20, 2018, to a close of $11.50 per share on April 23, 2018.
Shareholders have until July 16, 2018 to petition the court for lead plaintiff status. Your ability to share in any recovery does not require that you serve as lead plaintiff. You may choose to be an absent class member.
