About the Company

Entasis Therapeutics is a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel antibacterial products to treat serious infections caused by multidrug-resistant Gram-negative bacteria. Entasis’ targeted-design platform has produced a pipeline of product candidates, including SUL-DUR (targeting A. baumannii infections) being evaluated in Phase 3 clinical trials, zoliflodacin (targeting Neisseria gonorrhoeae) being evaluated in Phase 3 clinical trials, and ETX0282CPDP (targeting Enterobacteriaceae infections). Entasis is also using its platform to develop a novel class of antibiotics, non-β-lactam inhibitors of the penicillin-binding proteins (NBPs) (targeting Gram-negative infections).
