(“Tetraphase” or the “Company”) (NASDAQ: TTPH ) and certain of its officers, on behalf of shareholders who purchased or otherwise acquired Tetraphase securities: 1) pursuant and/or traceable to its registration statement and prospectus issued in connection with the July 2017 secondary public offering (“SPO” or the “Offering”); and/or, 2) acquired Tetraphase securities between March 8, 2017 and February 13, 2018, inclusive (the “Class Period”). Such investors are encouraged to join this case by visiting the firm’s site: www.bgandg.com/ttph .
