Karyopharm Therapeutics Inc Loss Submission Form

The Klein Law Firm announces that a class action complaint has been filed on behalf of shareholders of Karyopharm Therapeutics Inc (NASDAQGS: KPTI) who: (1) purchased shares of Karyopharm’s common stock between March 2, 2017 and February 22, 2019, inclusive; (2) purchased Karyopharm shares in or traceable to the Company’s public offering of common stock conducted on or around April 28, 2017; or (3) purchased Karyopharm shares in or traceable to the Company’s public offering of common stock conducted on or around May 7, 2018. The action, which was filed in the United States District Court for the District of Massachusetts, alleges that the Company violated federal securities laws.

In particular, the Karyopharm lawsuit alleges that throughout the Class Period, the Company continued to tout the commercial prospects for selinexor and consistently described selinexor as having a “predictable and manageable tolerability profile” and a “very nice safety profile,” and assured investors that it was “well tolerated” by patients. Karyopharm also claimed that selinexor had the potential to be used as a new treatment for MM, with limited and manageable side effects. As a result of these misrepresentations, Karyopharm shares traded at artificially inflated prices during the Class Period.

Shareholders have until September 23, 2019 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.
