Tetraphase Begins Phase III Dosing of Antibiotic Candidate


Tetraphase Pharmaceuticals TTPH announced that it has begun dosing in the phase III IGNITE4 study on its lead antibiotic candidate, eravacycline.

IGNITE4 is evaluating the efficacy and safety of twice-daily intravenous (IV) eravacycline compared to meropenem for the treatment of complicated intra-abdominal infections (cIAI).

Eravacycline is a novel antibiotic that is being developed for the treatment of serious and life-threatening bacterial infections, including those caused by multidrug-resistant (MDR) pathogens. It is currently in phase III trials.

Tetraphase expects to present top-line data from IGNITE4 in the fourth quarter of 2017.

Under the IGNITE program, Tetraphase has already completed two phase III studies (n>1300) – IGNITE1 for cIAI and IGNITE2 for complicated urinary tract infections (cUTI).

The company plans to submit a new drug application (NDA) for IV eravacycline for the treatment of cIAI based on data from IGNITE1 and IGNITE4, assuming positive results from the latter. Moreover, the company plans to initiate IGNITE3, a phase III trial to evaluate once-daily IV eravacycline for the treatment of complicated cUTI. Tetraphase is also conducting a phase I clinical program on an oral dosing regimen of eravacycline.

Apart from eravacycline, Tetraphase’s pipeline also includes TP-271 and TP-6076. Both the candidates are presently in phase I clinical trials.
