DEADLINE ALERT: Brower Piven Reminds Investors Of The March 13, 2017 Deadline In Class Action Lawsuit And Encourages Investors With Losses In Excess of $100,000 From Investment In Seattle Genetics Inc. (SGEN) To Contact The Firm

STEVENSON, Md., March 05, 2017 -- The securities litigation law firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been commenced in the United States District Court for the Western District of Washington on behalf of purchasers of Seattle Genetics Inc. (Nasdaq:SGEN) (“Seattle Genetics” or the “Company”) securities during the period between October 27, 2016 and December 23, 2016, inclusive (the “Class Period”). Investors who wish to become proactively involved in the litigation have until March 13, 2017 to seek appointment as lead plaintiff.

If you wish to choose counsel to represent you and the Class, you must apply to be appointed lead plaintiff and be selected by the Court. The lead plaintiff will direct the litigation and participate in important decisions including whether to accept a settlement for the Class in the action. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in Seattle Genetics securities during the Class Period. Members of the Class will be represented by the lead plaintiff and counsel chosen by the lead plaintiff. No class has yet been certified in the above action.

The complaint accuses the defendants of violations of the Securities Exchange Act of 1934 by virtue of the defendants’ failure to disclose during the Class Period that Seattle Genetics’ vadastuximab talirine presents a significant risk of fatal hepatotoxicity and that the Company had overstated the viability of vadastuximab talirine as a treatment for acute myeloid leukemia (“AML”).

According to the complaint, following a December 27, 2016 press release announcing that the U.S. Food and Drug Administration had placed a clinical hold or partial clinical hold on several early stage trials of vadastuximab talirine to evaluate the potential risk of hepatotoxicity, the value of Seattle Genetics shares declined significantly.

If you have suffered a loss in excess of $100,000 from investment in Seattle Genetics securities purchased on or after October 27, 2016 and held through the revelation of negative information during and/or at the end of the Class Period and would like to learn more about this lawsuit and your ability to participate as a lead plaintiff, without cost or obligation to you, please visit our website at http://www.browerpiven.com/currentsecuritiescases.html.
