This lawsuit is for anyone who acquired securities in Tetraphase Pharmaceuticals, Inc. (NASDAQ: TTPH) from March 8, 2017 through February 13, 2018.

The lawsuit alleges that the Company and certain of its executives violated federal law. Specifically, the lawsuit alleges that, during the time period mentioned above, the Company misled investors regarding its financial condition. More specifically, the lawsuit alleges that Company knew, but failed to timely disclose, that its clinical trial of intravenous Eravacycline for the treatment of complicated urinary tract infections would not show the drug to be a sufficiently better treatment for those infections than the leading treatment, and therefore would not receive FDA approval.

After trading closed on February 13, 2018, the Company announced that it had failed to reach its efficacy endpoint for clinical trial of intravenous Eravacycline for the treatment of complicated urinary tract infections, admitted that it knew earlier that the trial was not meeting its goal because the Company had added over 200 more patients than previously disclosed to the clinical trial in an attempt to get the desired result, and also announced that it would be ending the testing of the drug. On this news, the price of the Company's stock dropped precipitously on unusually heavy trading volume.

The Law Offices of Howard G. Smith seeks to recover damages on behalf of class members. If you acquired securities in Tetraphase Pharmaceuticals, Inc.
