Case Details


The law firm of Barbuto & Johansson, P.A. and Director of Client Relations Neil Rothstein, Esq. remind investors that they have until September 23, 2019 to file lead plaintiff applications in a securities class action lawsuit against Karyopharm Therapeutics Inc. (NasdaqGS: KPTI), if they purchased the Company’s shares issued in connection with its April 2017 or May 2018 public offering or between March 2, 2017 and February 22, 2019, inclusive (the “Class Period”).

Karyopharm and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws.

On February 22, 2019, the Federal Drug Administration (“FDA”) reported serious concerns with the Company’s drug, selinexor. Specifically, the FDA concluded that, contrary to the Company’s prior assurances, “[t]reatment with selinexor is associated with significant toxicity” with “limited efficacy.”

On this news, the price of Karyopharm’s shares plummeted.
