On February 13, 2018, post-market, Tetraphase announced top-line results from its IGNITE3 Phase 3 clinical trial
of eravacycline in complicated urinary tract infection (“cUTI”), disclosing that eravacycline did not achieve co-primary endpoints
in the trial. On this news, Tetraphase’s stock price fell $3.28 per share, or 60.41%, to close at $2.15 per share on February
14, 2018. Then, on March 6, 2017, Tetraphase reported its financial and operating results for the quarter and year ended
December 31, 2017, and advised investors that given the results of the IGNITE3 study, the Company did not plan to further evaluate
eravacycline in cUTI and had ceased its development of an oral formulation of eravacycline for the treatment of cUTI.
