According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (1) data from the Phase 2 SOPRA trial (“SOPRA”) demonstrated that the Company’s lead drug candidate, selinexor, was associated with significant toxicity, was not well-tolerated among patients with AML, and resulted in a higher risk of death; (2) patients experienced serious drug-related side effects, with eighty percent of the AML patients treated with selinexor trial experiencing a serious adverse event; (3) as a result, nearly half of the acute myeloid leukemia (“AML”) patients were forced to withdraw from the SOPRA trial because of drug-related toxicity (4) in addition, the toxicity profile of selinexor for the treatment of patients with multiple myeloma in Part 2 of the Phase 2b STORM study was similar to that observed in AML patients treated with selinexor in the SOPRA study; and (5) as a result, Karyopharm’s public statements were materially false and misleading at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.
