The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors related to its secondary offering on March 8, 2017.
On or about March 8, 2017, Prothena Corporation plc completed a secondary offering of 2,700,000 of its ordinary shares at a price of $57.50 per share.
On November 8, 2017, Kerrisdale, an investment research firm, published a 27-page report exposing that Prothena’s Phase 1/2 study results were misleading. On this news, the price of Prothena stock declined from $60.96 per share on November 7, 2017, to $56.24 per share on November 8, 2017, a drop of 7.8%.

The Company advised investors that "[b]ased on the results from the Phase 2b PRONTO study, which did not meet its primary or secondary endpoints, the Company 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." On this news, Prothena’s share price fell $25.34, or 68.78%, to close at $11.50 on April 23, 2018.
