Tetraphase Pharmaceuticals Announces FDA Acceptance for Filing of its NDA Submission for Eravacycline for the Treatment of Complicated Intra-Abdominal Infections
WATERTOWN, Mass., Feb. 27, 2018 (GLOBE NEWSWIRE) -- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH), a biopharmaceutical company focused on developing and commercializing novel antibiotics to treat life-threatening multidrug-resistant (MDR) infections, today announced that it has received notification from the U.S. Food and Drug Administration (FDA) that the FDA has completed its initial 60-day review of the New Drug Application (NDA) for eravacycline for the treatment of complicated intra-abdominal infections (cIAI), and determined that the application is sufficiently complete to permit a substantive review. The PDUFA (Prescription Drug User Fee Act) goal date for the completion of the FDA’s review of the eravacycline NDA is set for August 28, 2018. This date reflects a priority 6-month review period.
“The FDA’s acceptance for review of our NDA submission for IV eravacycline in cIAI marks an important step in our goal to bring this important new treatment option to patients in need,” said Guy Macdonald, President and CEO of Tetraphase. “We believe that eravacycline has the potential to play a key role in the treatment of serious intra-abdominal infections, particularly Gram-negative infections, and we look forward to providing an update on a regulatory decision in August as we continue to prepare for a commercial launch."
The NDA submission includes data from the IGNITE1 and IGNITE 4 phase 3 clinical trials, in which twice-daily IV eravacycline was well tolerated and achieved high clinical cure rates in patients with cIAI. Both studies demonstrated statistical non-inferiority of eravacycline to two widely used comparators – ertapenem in IGNITE1 and meropenem in IGNITE4 – for the primary efficacy endpoint of clinical response at the test-of-cure (TOC) visit.
Eravacycline is a novel, fully-synthetic fluorocycline antibiotic being developed for the treatment of complicated intra-abdominal infections (cIAI) and other serious infections, including those caused by multidrug-resistant (MDR) pathogens that have been highlighted as urgent public health threats by both the World Health Organization and the U.S. Centers for Disease Control & Prevention (CDC). In clinical trials, eravacycline has demonstrated potent activity against MDR pathogens, including carbapenem-resistant enterobacteriaceae (CRE), Acinetobacter baumannii, and colistin-resistant bacteria carrying the mcr-1 gene.
Eravacycline was investigated for the treatment of cIAI as part of the Company's IGNITE (Investigating Gram-negative Infections Treated with Eravacycline) phase 3 programs. In IGNITE1, a pivotal phase 3 trial in patients with cIAI, twice-daily IV eravacycline met the primary endpoint by demonstrating statistical non-inferiority of clinical response compared to ertapenem, was well tolerated, and achieved high cure rates in patients with Gram-negative pathogens, including resistant isolates. The IGNITE1 data is serving as the basis of the Marketing Authorization Application (MAA) for IV eravacycline for the treatment of patients with cIAI now under review by the European Medicines Agency (EMA). In IGNITE4, a second phase 3 clinical trial in patients with cIAI, twice-daily IV eravacycline met the primary endpoint by demonstrating statistical non-inferiority of clinical response compared to meropenem, was well tolerated, and achieved high cure rates. The Company has used the results from IGNITE1 and IGNITE4 to support a New Drug Application (NDA) submission for IV eravacycline in cIAI. To date, eravacycline has been administered to over 2,700 patients.
About Complicated Intra-abdominal Infections (cIAI)
Intra-abdominal infection (IAI) is a common problem in clinical practice and comprises a wide variety of disease processes. IAI is classified as uncomplicated or complicated based on the extent of the infection. Complicated intra-abdominal infection extends beyond the source organ into the peritoneal space (the space between the two membranes that separate the organs in the abdominal cavity from the abdominal wall) as a result of perforation or other damage to the gastrointestinal tract. cIAI diagnoses include intra-abdominal abscess, stomach or intestinal perforation, peritonitis, appendicitis, cholecystitis, or diverticulitis. Different bacterial pathogens are responsible for cIAI, including Gram-negative aerobic bacteria, Gram-positive bacteria, and anaerobic bacteria, and there are also mixed infections. IAI is an important cause of morbidity and mortality and is the second most common cause of infectious mortality in the intensive care unit. Early detection, containment and appropriate antimicrobial treatment are essential to the successful treatment of IAI. This is even more critical with increasing rates of infections caused by drug-resistant bacteria, which limit the effectiveness of currently available antibiotics.
