Tetraphase Accused of Misrepresenting Enrollment for Its Drug Trial

According to the complaint, Tetraphase reported that enrollment was
progressing well for the company's IGNITE3 trial. However, in reality
Tetraphase increased the patient enrollment in its IGNITE3 trial from
1,000 patients to 1,200 patients because the existing population was
inadequate to meet the trial's primary endpoints. On February 13, 2018,
Tetraphase announced top-line results from its IGNITE3 trial for the
treatment of patients with complicated urinary tract infections,
revealing that eravacycline did not achieve co-primary endpoints. The
news caused Tetraphase's stock to fall over 60%, closing at only $2.15
per share on February 14, 2018. The stock now trades at just $0.72.
