Conditions: Urinary Tract Infection Complicated Acute Pyelonephritis
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 550
Healthy volunteers: no

Brief summary:
Meropenem-vaborbactam is being compared to piperacillin-tazobactam in the treatment of adults with complicated urinary tract infection (cUTI) or acute pyelonephritis (AP).

Detailed description:
In the current era of increased resistance to extended spectrum cephalosporins, carbapenem antimicrobial agents are frequently the antibiotics of "last defense" for the most resistant pathogens in serious infections, including those found in cUTIs. The recent dissemination of serine carbapenemases in Enterobacteriaceae in many hospitals worldwide now poses a considerable threat to the carbapenems and other members of the beta-lactam class of antimicrobial agents.

Rempex is developing meropenem-vaborbactam administered as a fixed combination by intravenous infusion to treat serious Gram-negative infections such as cUTIs, including those infections caused by bacteria resistant to currently available carbapenems.

Arms:
arm 1: Meropenem-vaborbactam (meropenem 2 grams \[g\] plus vaborbactam 2 g), infused in 250 milliliters (mL) normal saline, administered intravenously (IV) over 3 hours, every 8 hours (q8h), with 100 mL saline administered over 30 minutes q8h. Levofloxacin tablets administered orally as a 500-milligram (mg) dose every 24 hours (q24h) after a minimum of 15 doses of IV meropenem-vaborbactam plus saline, if clinically indicated. Total treatment was 10 days, unless a participant had baseline bacteremia where up to 14 days of therapy could be administered IV. arm 2: Piperacillin-tazobactam (piperacillin 4 g plus tazobactam 0.5 g), infused in 100 mL normal saline, administered IV over 30 minutes, q8h, with 250 mL saline administered over 30 minutes q8h. Levofloxacin tablets administered orally as a 500-mg dose q24h after a minimum of 15 doses of IV piperacillin-tazobactam plus saline, if clinically indicated. Total treatment was 10 days, unless a participant had baseline bacteremia where up to 14 days of therapy could be administered IV.
