SOUTH SAN FRANCISCO, Calif., June 11, 2018 (GLOBE NEWSWIRE) -- Achaogen, Inc. (NASDAQ:AKAO), a late-stage biopharmaceutical company developing innovative antibacterials addressing multi-drug resistant (MDR) gram-negative infections, today announced data highlights from five presentations on plazomicin, the Company's lead product candidate, for the treatment of serious bacterial infections due to MDR Enterobacteriaceae. The presentations took place at ASM Microbe 2018 being held in Atlanta, Georgia from June 7 to 11, 2018. The presentations are summarized as follows:
Pharmacokinetic-Pharmacodynamic (PK-PD) Target Attainment Analyses to Support Plazomicin Dose Selection and Recommendations for Interpretive Criteria for In Vitro Susceptibility Testing for Enterobacteriaceae (ENT) (Poster 518)
S. M. Bhavnani, J. P. Hammel, M. Trang, A. Kim, K. M. Krause, M. Castanheira, C. M. Rubino, P. G. Ambrose
The authors concluded that the total-drug plasma AUC values associated with the plazomicin clinical dose achieved ≥90% probability of target attainment across the plazomicin MIC distribution for Enterobacteriaceae in patients with complicated urinary tract infections (cUTI), including acute pyelonephritis (AP), bloodstream infection (BSI), or hospital-acquired bacterial pneumonia (HABP)/ventilator-associated bacterial pneumonia (VABP).
Population Pharmacokinetic Analyses for Plazomicin Using Pooled Data from Phase 1, 2 and 3 Studies (Poster Talk 3, Poster 516)
M. Trang, J. Seroogy, S. A. Van Wart, S. M. Bhavnani, A. Kim, P. G. Ambrose, C. M. Rubino
The authors developed a population pharmacokinetic model for conducting simulations and generating individual estimates of drug exposure for use in pharmacokinetic-pharmacodynamic analyses (PK-PD).
Activity of Plazomicin and Comparator Agents Tested against Contemporary Clinical Isolates Collected Worldwide (Poster 645)
M. Castanheira, J. M. Streit, S. Arends, R. K. Flamm
The authors evaluated the activity of plazomicin and comparator agents against thousands of clinical isolates collected worldwide during 2017. These data confirm the activity of plazomicin against contemporary Enterobacteriaceae clinical isolates collected worldwide, including most carbapenem-resistant Enterobacteriaceae (CRE) isolates.
Evaluation of Plazomicin (PLZ), Tigecycline (TGC), and Meropenem (MEM) Pharmacodynamic (PD) Exposure against Carbapenem-Resistant Enterobacteriaceae (CRE) in Evaluable Patients from the CARE Study (ACHN-490-007) (Poster 646)
J. L. Kuti, A. Kim, D. J. Cloutier, D. P. Nicolau
The authors evaluated the pharmacodynamic exposures of plazomicin and combination agents, meropenem and tigecycline, from patients in the CARE study who received plazomicin in combination with either TGC or MEM. The pharmacodynamic exposure was achieved for PLZ in all evaluable patients but was not consistently achieved for either TGC or MEM in patients with life-threatening CRE infections. Rates of microbiological eradication and clinical response were high in plazomicin-treated patients, regardless of whether or not adequate exposure of TGC or MEM was achieved.
A Multi-Site Study Comparing a Commercially Prepared Dried MIC Susceptibility System to the CLSI/ISO Broth Microdilution Method for Plazomicin Using Non-Fastidious Gram-Negative Organisms (Poster 236)
S. M. Andrus, C. C. Knapp, N. M. Holliday, S. B. Killian, J. M. Lindley, J. M. Streit, B. J. Olson, T. R. Fritsche, J.W. Decousser, E. Scopes, A. M. Leonte, A. W. Serio
Antibiotic susceptibility testing (AST) confirms antibiotic susceptibility to specific organisms. In this study, the authors demonstrated that the Sensititre system is an acceptable method for susceptibility testing of plazomicin in the laboratory when compared to the reference standard of broth microdilution method.
