Business Wire
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 that 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.

and how to seek appointment as lead plaintiff should click here or

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.
