Bragar Eagel & Squire, P.C. reminds investors that a class action lawsuit has been filed in the U.S. District Court for the Southern District of New York on behalf of all persons or entities who purchased or otherwise acquired Stemline Therapeutics, Inc. (NASDAQ:STML) securities between January 6, 2017 and February 1, 2017 (the "Class Period"). The Complaint alleges that on January 6, 2017, Stemline hosted a conference call which revealed that the outcome of one its Company's clinical stage product candidates, SL-401, was promising. The call revealed that both the phase 1/2 investigative sponsored study and the phase 2 trial of SL-401, were encouraging on the duration of response and the progression-free period, and that there had been consistent, manageable, and predictable safety profiles. Stemline further noted that the company was pleased with the outcome and viewed it as a favorable path forward for Stemline's investors, the medical community at large, and BPDCN patients. The Complaint further alleges that on January 20, 2017, Stemline announced the price of its secondary public offering (the "Secondary Public Offering") of 4.5 million shares of its common stock at $10.00 per share, with expected gross proceeds of $45 million. Stemline filed a prospectus supplement (the "Prospectus") with the U.S. Securities and Exchange Commission for the Secondary Public Offering that detailed that SL-401's safety profile "has continued to remain predicable and manageable over increasing treatment duration, drug exposure, and patient experience." The Prospectus also touted SL-401's favorable clinical data. The Complaint also alleges that Stemline officials failed to disclose that a cancer patient in one of its trials died from a severe side effect due to SL-401 on January 18, 2017, one day prior to the Company's Secondary Public Offering. On February 2, 2017, TheStreet.com revealed the death of the patient and Stemline later issued a press release entitled, "Stemline Therapeutics Provides Update on Pivotal BPDCN Trial," confirming the death. Following this news, Stemline shares declined $4.15 per share, or over 42.5%, to close at $5.60 on February 2, 2017.
