Tetraphase reported that its annual Total Revenue declined from $10.49 million in 2013 to $9.10 million in 2014 and that its respective Net Loss increased from $29.64 million to $66.74 million. Tetraphase grew from May 2014's $8.83 per share to as high as $51.75 per share in July 2015.

On September 8, 2015, Tetraphase announced that the pivotal portion of its IGNITE2 phase 3 clinical trial of Eravacycline did not achieve its primary endpoint. Following this news, Tetraphase shares fell 80% in market value from the September 8, 2015 close of $44.78 to just $8.36 per share at September 10, 2015's closing.
