or contact Reed Kathrein, who is leading the firm's investigation, by calling 510-725-3000 or emailing

[email protected].

The investigation focuses on whether the Company's registration statements for the 2017 and 2018 follow-on offerings misled investors about the safety and efficacy of selinexor, a drug intended for the treatment of various types of cancer that Karyopharm was developing. More specifically, Karyopharm's offering documents claimed that selinexor studies showed the drug was "well-tolerated" by patients and explained there were "no new clinically significant adverse events in the patients receiving selinexor."

However, on February 22, 2019, the FDA disclosed that (i) a previously cancelled selinexor trial resulted in "worse overall survival" for certain patients, and (ii) "[t]reatment with selinexor is associated with significant toxicity" and has "limited efficacy."

"We're focused on investors' losses and the extent to which Defendants' statements about selinexor's safety and efficacy may have misled investors," said Hagens Berman partner Reed Kathrein.

Whistleblowers: Persons with non-public information regarding Karyopharm should consider their options to help in the investigation or take advantage of the SEC Whistleblower program. Under the new program, whistleblowers who provide original information may receive rewards totaling up to 30 percent of any successful recovery made by the SEC.
