PHILADELPHIA, April 24, 2018 /PRNewswire/ -- Kehoe Law Firm, P.C. is conducting a securities investigation on behalf of investors of Prothena Corporation plc (NASDAQ: PRTA) to determine whether Prothena Corporation and certain of its officers or directors engaged in securities fraud or other unlawful business practices.

Prothena Discontinues Development of NEOD001 for AL Amyloidosis; PRTA Stock Drops $25.34, or 68.78% to Close at $11.50 on April 23, 2018

On April 23, 2018, Prothena Corporation announced that it

. . . is discontinuing development of NEOD001, an investigational antibody that was being evaluated for the treatment of AL amyloidosis. The decision was based on results from the Phase 2b PRONTO study and a futility analysis of the Phase 3 VITAL study.

Based on the results from the Phase 2b PRONTO study, which did not meet its primary or secondary endpoints, [Prothena] asked the independent data monitoring committee (DMC) of the Phase 3 VITAL study to review a futility analysis of the ongoing VITAL study. The DMC recommended discontinuation of the VITAL study for futility. [Prothena] therefore decided to discontinue all development of NEOD001, including the VITAL study as well as the open label extension studies. (Emphasis added)
