About ACHN-490
Achaogen’s most advanced compound, ACHN-490, has been chemically engineered to retain activity against bacteria resistant to carbapenems, cephalosporins, fluoroquinolones, tetracyclines, and legacy aminoglycosides. The compound has demonstrated bactericidal activity in vitro and efficacy in preclinical studies against systemic infections caused by MDR Gram-negative bacteria (e.g., K. pneumoniae, E. coli, and P. aeruginosa) and MRSA. ACHN-490 Injection is currently being investigated in a randomized, doubleblind, comparator-controlled Phase 2 clinical study for the treatment of complicated urinary tract infection (cUTI), the most commonly treated hospital infections in the U.S., and acute pyelonephritis.
