SHAREHOLDER ALERT: Bronstein, Gewirtz & Grossman, LLC Announces Investigation of Portola Pharmaceuticals Inc. (PTLA)

NEW YORK, Sept. 6, 2017 /PRNewswire/ -- Attorney Advertising - Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of Portola Pharmaceuticals Inc. ("Portola" or the "Company") (NASDAQ: PTLA). Such investors are encouraged to obtain additional information and assist the investigation by visiting the firm's site: www.bgandg.com/ptla.

The investigation concerns whether Portola and certain of its officers and/or directors have violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.

On September 5, 2017, after the market closed, Portola announced that the Company's oral anticoagulant Bevyxxa (betrixaban) would launch in November at the earliest, and possibly as late as the first quarter of 2018.  Having previously projected a September 2017 launch for Bevyxxa, Portola advised investors that the U.S. Food and Drug Administration would require additional time to complete review of a post-approval change to the product.  Following this news, Portola's share price has fallen as much as $3.83, or 6.44%, during intraday trading on September 6, 2017.
