Urinary Tract Infection: Zemdri (plazomicin)
Indication: Indicated for complicated urinary tract infections (cUTIs) in adults, including pyelonephritis caused by the following susceptible microorganism(s): E coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter cloacae.
Mechanism: Aminoglycoside antibiotic that has been engineered to overcome aminoglycoside-modifying enzymes, the most common aminoglycoside-resistance mechanism in Enterobacteriaceae, and has in vitro activity against extended-spectrum beta-lactamase-producing, aminoglycoside-resistant, and carbapenem-resistant isolates.
Dosage: 15 mg/kg IV every 24 hr for up to 7 days.
Approval was based on the phase 3 evaluating plazomicin in cUTI (EPIC) clinical trial (N=388). Plazomicin was noninferior compared with meropenem for clinical cure and microbiologic eradication at day 5 and test-of-cure at about day 17.
