Top-line IGNITE4 Data Expected in 4Q 2017
Results to Support NDA Filing for IV Eravacycline in cIAI
"Patient dosing is now underway in IGNITE4, and we continue to expect top-line data in the fourth quarter of 2017. If successful, these data, along with data from our positive IGNITE1 study in cIAI, will support a new drug application (NDA) submission for IV eravacycline in cIAI," said
IGNITE4 is a phase 3 randomized, double-blind, double-dummy, multicenter, prospective study that is designed to assess the efficacy, safety and pharmacokinetics of twice-daily eravacycline (1.0 mg/kg every 12 hours) compared with meropenem (1g every 8 hours) for the treatment of cIAI. The study is expected to enroll approximately 450 adult patients at 75 centers worldwide. The primary endpoint of IGNITE4 is clinical response at the test-of-cure (TOC) visit, which occurs 25 to 31 days after the initial dose of the study drug. The primary efficacy analysis will be conducted using a 12.5% non-inferiority margin in the microbiological intent-to-treat (micro-ITT) population.

Eravacycline is currently being investigated in the Company's phase 3 IGNITE (Investigating Gram-negative Infections Treated with Eravacycline) program. To date, eravacycline has been tested in over 1,300 patients and has been tested in two completed phase 3 trials - IGNITE1 in patients with cIAI and IGNITE2 in patients with cUTI. In IGNITE1, twice-daily IV eravacycline met the primary endpoint by demonstrating statistical non-inferiority inferiority of clinical response compared to ertapenem, was well tolerated, and achieved high cure rates in patients with Gram-negative pathogens, including resistant isolates. Tetraphase is currently evaluating eravacycline in a second phase 3 clinical trial in patients with cIAI (IGNITE4) comparing twice-daily IV eravacycline to meropenem. Assuming a positive outcome in IGNITE4, the Company plans to use the results from IGNITE1 and IGNITE4 to support an NDA submission for IV eravacycline for the treatment of patients with cIAI. The Company plans to initiate IGNITE3, an additional phase 3 trial evaluating once-daily IV eravacycline in patients with complicated cUTI. Assuming a positive outcome, the Company plans to use the results from IGNITE3 to support a supplemental NDA (sNDA) submission for eravacycline in cUTI. In parallel, Tetraphase is continuing its efforts to develop an oral dose formulation of eravacycline. A phase 1 clinical program is ongoing which is designed to evaluate and optimize the oral dosing regimen for eravacycline.
