SOUTH SAN FRANCISCO, Calif., Sept. 04, 2018 (GLOBE NEWSWIRE) -- Achaogen, Inc. (NASDAQ: AKAO), a biopharmaceutical company developing innovative antibacterials addressing multi-drug resistant (MDR) gram-negative infections, today highlighted four poster presentations about plazomicin at the ESCMID/ASM Conference on Drug Development to Meet the Challenge of Antimicrobial Resistance that is being held from September 4 to 7, 2018 in Lisbon, Portugal. The presentations are summarized as follows:
Assessment of AUC-Based Therapeutic Drug Management (TDM) Algorithms for Plazomicin Therapy in Patients with Bloodstream Infection (BSI), Trang et al. (Poster 84)
Pharmacokinetic variability in critically ill patients with serious bacterial infections is a known issue. Modeling and simulations using data from the subset of Phase 3 CARE trial patients with BSI due to carbapenem-resistant Enterobacteriaceae (CRE) suggest that, relative to dosing based on baseline renal function alone, using an Area Under the Curve (AUC)-based TDM approach may result in a higher percentage of exposures within the targeted AUC range.
Pharmacokinetics-Pharmacodynamics (PK-PD) of Plazomicin (PLZ) against Carbapenem-Resistant Enterobacteriaceae (CRE) in Neutropenic Murine Thigh Infection and Pneumonia Models, Louie et al. (Poster 100)
The authors analyzed data from murine infection models to identify the pharmacodynamic index and exposure intensity associated with optimized killing of CRE. The results suggest that exposures associated with a 15 mg/kg once daily dose in patients is suitable for treating CRE with a minimum inhibitory concentration (MIC) breakpoint of 4 mg/L.
Encore Presentation: Population Pharmacokinetic Analyses for Plazomicin Using Pooled Data from Phase 1, 2 and 3 Studies, Trang et al. (Poster 86)
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).
Encore Presentation: Pharmacokinetic-Pharmacodynamic Target Attainment Analyses to Support Plazomicin Dose Selection and Recommendations for Interpretive Criteria for In Vitro Susceptibility Testing for Enterobacteriaceae, Bhavnani et al. (Poster 85)
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).
The posters are available on the Achaogen website. More information about the meeting is available on the ESCMID/ASM website.
