Tetraphase (TTPH) Alert: Johnson Fistel Reminds Tetraphase Pharmaceuticals Investors of Class Action Lawsuit; Investors with Losses Encouraged to Contact Firm

SAN DIEGO- PRNewswire —August 2, 2018

Shareholder Rights Law Firm Johnson Fistel, LLP reminds investors that a class action lawsuit has been filed against Tetraphase Pharmaceuticals, Inc. (”Tetraphase”) (NASDAQ: TTPH) and certain of its officers. The class action is on behalf of persons and entities that: a) acquired Tetraphase securities pursuant and traceable to the Company’s registration statement and prospectus in connection with the Company’s July 2017 secondary public offering (“SPO”); or, b) acquired Tetraphase securities between March 8, 2017 and February 13, 2018, inclusive (the “Class Period”).

The complaint alleges that throughout the Class Period, Defendants made materially false and misleading statements and failed to disclose that: (1) Tetraphase was increasing the patient enrollment in its IGNITE3 trial from 1,000 patients to 1,200 patients to meet the trial’s primary endpoints (within the 10% non-inferiority margin); (2) The enrollment of more patients in the trial indicated that the existing population was inadequate to meet the trial’s primary endpoints; and (3) consequently, Defendants’ statements about Tetraphase’s business, operations, and prospects, were materially false and misleading.
