Robbins Geller Rudman & Dowd LLP Files Class Action Suit Against Stemline Therapeutics, Inc.

SAN DIEGO, Feb. 10, 2017 /PRNewswire/ -- Robbins Geller Rudman & Dowd LLP ("Robbins Geller") (http://www.rgrdlaw.com/cases/stemline/) today announced that a class action has been commenced on behalf of purchasers of Stemline Therapeutics, Inc. ("Stemline") (NASDAQ: STML) publicly traded securities during the period between January 6, 2017 and February 1, 2017 (the "Class Period").  This action was filed in the Southern District of New York and is captioned Soileau v. Stemline Therapeutics, Inc., et al., No. 17-cv-01003.

If you wish to serve as lead plaintiff, you must move the Court no later than 60 days from February 3, 2017.  If you wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact plaintiff's counsel, Darren Robbins of Robbins Geller at 800/449-4900 or 619/231-1058, or via e-mail at [email protected].  If you are a member of this class, you can view a copy of the complaint as filed at http://www.rgrdlaw.com/cases/stemline/.  Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

The complaint charges Stemline and certain of its officers and/or directors with violations of the Securities Exchange Act of 1934.  Stemline is a clinical-stage biopharmaceutical company focused on discovering, acquiring, developing and commercializing oncology therapeutics.  The Company is developing several clinical stage product candidates, including SL-401, a targeted therapy directed to the interleukin-3 receptor present on a range of hematologic cancers.

The complaint alleges that throughout the Class Period, defendants made false and misleading statements and/or failed to disclose adverse information regarding the prospects for Stemline's SL-401 drug candidate, including that a cancer patient in a Stemline clinical trial for SL-401 had died from a severe side effect on January 18, 2017.  As a result of defendants' false statements and/or omissions, Stemline's stock traded at artificially inflated prices during the Class Period, reaching a high of $13.95 per share on January 10, 2017.

On January 19, 2017, Stemline issued a press release announcing a proposed follow-on public offering of the Company's common stock.  Subsequently, on January 20, 2017, Stemline announced the pricing of the offering of 4.5 million shares of the Company's common stock at $10.00 per share, with projected gross proceeds of $45 million to Stemline.

Then, on February 2, 2017, before the market opened, Adam Feuerstein published an article on TheStreet reporting that on January 18, 2017, a cancer patient in a clinical trial of SL-401 for the treatment of blastic plasmacytoid dendritic cell neoplasm ("BPDCN") had died from a severe side effect tied to the drug.  The article stated that on January 17, 2017, the patient had been diagnosed with capillary leak syndrome and had died the next day, "having received only two of the scheduled five doses of SL-401 of the initial treatment cycle."  Subsequently on February 2, 2017, the Company issued a press release that provided an update on its ongoing trial for the treatment of BPDCN utilizing SL-401, confirming that BPDCN "has no approved treatment."  The Company admitted receiving the report regarding the patient death on January 18, 2017, but continued with its stock offering on January 19, 2017, without disclosing the patient death to investors.  As a result of this news, the price of Stemline stock dropped $4.15 per share, to close at $5.60 per share on February 2, 2017, a decline of 42% on volume of nearly 3.7 million shares traded.
