Tetraphase Pharmaceuticals' TP-6076 Selected by CARB-X to Receive $4 Million in Research Funding

Funding initiative focused on urgent public health crisis of antibiotic resistance

WATERTOWN, Mass., March 30, 2017 (GLOBE NEWSWIRE) -- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH), a clinical stage biopharmaceutical company developing novel antibiotics to treat life-threatening multidrug-resistant (MDR) infections, today announced that its pipeline candidate TP-6076 was selected to receive $4 million in research funding from the Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X), an international, public-private partnership focused on the discovery and development of new antimicrobial products to address the threat of antibiotic resistance.  In preclinical research, TP-6076 has demonstrated potent activity against MDR bacteria, particularly those considered to be urgent or serious threats by the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).

"The selection of TP-6076 as one of the first candidates in the CARB-X portfolio highlights the potential of this early stage antibiotic compound due to its exceptional in vitro potency against two of the most dangerous organisms, carbapenem-resistant Enterobacteriaceae (CRE) and carbapenem-resistant Acinetobacter baumannii (CRAB)," said Guy Macdonald, President and CEO of Tetraphase. "This collaboration provides important non-dilutive funding dedicated to the advancement of TP-6076, which recently completed a phase 1 single-ascending dose clinical trial and for which we plan to report data in June at the American Society for Microbiology (ASM) and Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) 2017 joint annual meeting."

CARB-X was launched in July 2016 and represents the world's largest public-private funding initiative to accelerate the research and development of novel drugs, diagnostics and vaccines to protect human health from the most serious bacterial threats.  Companies with early stage projects were selected through a rigorous application process identifying programs that target one of the deadly antibiotic-resistant bacteria on the Serious or Urgent Threat List prepared by the CDC or on the Priority Pathogens list published by the WHO.
