NEW YORK--()--The following statement is being issued by Levi & Korsinsky, LLP:

To: All persons or entities who purchased or otherwise acquired securities of Tetraphase Pharmaceuticals Inc. (“Tetraphase”) (NASDAQ: TTPH) between March 5, 2015 and September 8, 2015.

or contact Joseph E. Levi, Esq. either via email at jlevi@zlk.com or by telephone at (212) 363-7500, toll-free: (877) 363-5972. There is no cost or obligation to you.

The complaint alleges that Tetraphase and certain insiders issued materially false and misleading statements to investors. In particular, it is alleged that throughout the class period, Tetraphase made positive statements about the efficacy and potential for its drug Eravacycline to achieve approval by the FDA, despite knowledge that a pivotal portion of its IGNITE2 phase 3 clinical trial for Eravacycline would fail to achieve its primary endpoint of statistical non-inferiority compared to the antibiotic Levofloxacin.

On September 8, 2015, the Company announced that the pivotal portion of its IGNITE2 phase 3 clinical trial of Eravacycline did not achieve its primary endpoint. Following this news, shares of Tetraphase fell from a close of $44.78 on September 8, 2015, to a close of $8.36 per share on September 10, 2015—a loss of more than 80% in market value.

If you suffered a loss in Tetraphase you have until March 28, 2016 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn’t require that you serve as a lead plaintiff.
