SHAREHOLDER ALERT: Bronstein, Gewirtz & Grossman, LLC Notifies Investors of Class Action Against Seattle Genetics, Inc. (SGEN) and Lead Plaintiff Deadline - March 13, 2017

NEW YORK, Jan. 11, 2017 /PRNewswire/ -- Attorney Advertising -- Bronstein, Gewirtz & Grossman, LLC notifies investors that a class action lawsuit has been filed against Seattle Genetics, Inc. ("Seattle Genetics" or the "Company") (NASDAQ: SGEN) and certain of its officers, and is on behalf of a class consisting of all persons or entities who purchased Seattle Genetics securities between October 27, 2016 through December 23, 2016, both dates inclusive (the "Class Period"). Such investors are advised to join this case by visiting the firm's site: http://www.bgandg.com/sgen.

This class action seeks to recover damages against Defendants for alleged violations of the federal securities laws under the Securities Exchange Act of 1934 (the "Exchange Act").

Seattle Genetics is a biotechnology company focused on developing and commercializing innovative, empowered monoclonal antibody-based therapies for the treatment of cancer. One of the Company's leading products in development is SGN-CD33A (vadastuximab talirine).  Throughout the Class Period, vadastuximab talirine was in clinical trials for various applications, including: (1) a Phase 1/2 trial in patients with acute myeloid leukemia (AML) as a pre-conditioning regimen prior to an allogenic stem cell transplant and as a maintenance therapy following transplant; (2) a Phase 1 trial evaluating vadastuximab talirine monotherapy, including a subset of older AML patients in combination with hypomethylating agents; and (3) a Phase 1 trial evaluating vadastuximab talirine combination treatment with 7+3 chemotherapy in newly diagnosed younger AML patients.

The Complaint that throughout the Class Period defendants issued materially false and misleading statements to investors and/or failed to disclose that: (1) vadastuximab talirine, one of Seattle Genetics' cancer drugs, presents a serious risk of fatal hepatotoxicity; (2) as such, Seattle Genetics had overstated the viability of vadastuximab talirine as a treatment for acute myeloid leukemia; and (3) consequently, defendants' public statements about Seattle Genetics' business, operations, and prospects, were false and misleading and/or lacked a reasonable basis.

On December 27, 2016, Seattle Genetics revealed that the U.S. Food and Drug Administration ("FDA") had placed a clinical hold or partial clinical hold on some early stage trials of vadastuximab talirine, its experimental cancer drug, to evaluate the potential risk of hepatotoxicity.  Seattle Genetics affirmed that six acute myeloid leukemia patients had been identified with liver toxicity and that four had died.  Following this news, Seattle Genetics stock dropped $9.50 per share, or 15.36%, to close at $52.36 on December 27, 2016.
