About Tetraphase Pharmaceuticals, Inc. [TTPH]: Tetraphase is a clinical-stage biopharmaceutical company using its proprietary chemistry technology to create novel antibiotics for serious and life-threatening multidrug-resistant (MDR) bacterial infections, including many of the MDR Gram-negative bacteria highlighted as urgent public health threats by the Centers for Disease Control and Prevention (CDC). Tetraphase's lead product candidate, eravacycline, is a fully synthetic tetracycline derivative being developed as a broad-spectrum intravenous and oral antibiotic for use as a first-line empiric monotherapy. The safety and efficacy of eravacycline is currently being studied in the IGNITE program (Investigating Gram-negative Infections Treated with Eravacycline). Two Phase 3 clinical trials are ongoing: IGNITE 1 for the indication of complicated intra-abdominal infections (cIAI) and IGNITE 2 for complicated urinary tract infections (cUTI). Tetraphase has created more than 3,000 novel tetracycline analogs using its technology platform; in addition to eravacycline, Tetraphase has generated multiple preclinical antibiotic candidates that are currently being evaluated for clinical suitability.
