According to the lawsuit, throughout the Class Period, Defendants' made material misrepresentations and omissions centered on Defendants' claims regarding results from clinical trials for selinexor's treatment of patients with certain types of blood cancer. Defendants claimed that selinexor studies showed that selinexor was "well-tolerated" by patients and explained that there were "no new clinically significant adverse events in the patients receiving selinexor." The Company repeatedly touted the commercial prospects for selinexor and consistently described selinexor as having a "predictable and manageable tolerability profile" and a "very nice safety profile." In reality, selinexor was unsafe with limited efficacy.

The truth was revealed on February 22, 2019, when the FDA released a briefing document expressing serious concerns about the safety and efficacy of selinexor. On this news the company's stock price fell from $8.97 per share to $5.07 per share.
