The complaint alleges that during the class period the Company made materially false and/or misleading statements and/or failed to disclose that: (i) a patient had died in the BPDCN Trial from capillary leak syndrome immediately prior to the Company's stock offering despite consistently stating that capillary leak syndrome was a potential side-effect of SL-401; and (ii) SL-401's safety profile did not remain predictable and manageable over increasing treatment duration, drug exposure, and patient experience as represented by the Defendants. If you suffered a loss in Stemline you have until April 4, 2017 to request that the Court appoint you as lead plaintiff.
