Experimental: Plazomicin
Patients received 15 milligrams per kilogram (mg/kg) plazomicin as an intravenous (IV) infusion once daily followed by matching placebo infusions 8 and 16 hours later. After a minimum of 4 days of IV plazomicin, patients could switch to 250 or 500 mg oral levofloxacin for a total duration of 7 to 10 days (IV plus oral).
|
Drug: plazomicin Drug: levofloxacin (oral) |
Active Comparator: Meropenem
Patients received 1.0 g meropenem as an IV infusion every 8 hours (q8h). After a minimum of 4 days of IV meropenem, patients could switch to 250 or 500 mg oral levofloxacin for a total duration of 7 to 10 days (IV plus oral).

- Percentage of Patients With Composite of Microbiological Eradication and Clinical Cure in the Microbiological Modified ITT (mMITT) Population at Day 5 [ Time Frame: Day 5 ]Microbiological eradication was defined as a urine culture that showed the pathogen found at baseline at ≥10^5 colony forming units per milliliter (CFU/mL) was reduced to <10^4 CFU/mL. Clinical Cure at Day 5: marked improvement evidenced by complete resolution or return to premorbid levels or reduction in severity of all core baseline symptoms with worsening of none, and no new symptoms developed. Failure: Lack of improvement in core baseline symptoms of cUTI or development of new core symptoms of cUTI; adverse event (AE) requiring the discontinuation of study drug and the patient required alternative non-study antibiotic therapy for the current cUTI. Indeterminate: Insufficient data are available to allow an evaluation of clinical outcome for any reason.
- Percentage of Patients With Composite of Microbiological Eradication and Clinical Cure in the mMITT Population at Test of Cure (TOC) [ Time Frame: Day 17 TOC Visit ]Microbiological eradication was defined as a urine culture that showed the pathogen found at baseline at ≥10^5 CFU/mL was reduced to <10^4 CFU/mL. Clinical Cure at TOC Visit: the complete resolution or return to premorbid levels of core symptoms of cUTI and no new symptoms develop, and no use of non-study antibiotic therapy for the current cUTI. Failure: Persistence of one or more core symptom of infection or reappearance of or development of new core symptoms that require alternative non-study antibiotic therapy for the current cUTI. Indeterminate: Insufficient data are available to allow an evaluation of clinical outcome for any reason.
- Percentage of Patients With Composite of Microbiological Eradication and Clinical Cure in the ME Population at Day 5 [ Time Frame: Day 5 ]Microbiological eradication: urine culture showed the pathogen found at baseline at ≥10^5 CFU/mL was reduced to <10^4 CFU/mL. Clinical Cure Day 5: Marked improvement defined as complete resolution or return to premorbid levels or reduction in severity of all core baseline symptoms with worsening of none, and no new symptoms develop. Failure Day 5: Lack of improvement in core baseline symptoms of cUTI or development of new core symptoms of cUTI; AE requiring the discontinuation of study drug and the patient required alternative non-study antibiotic therapy for the current cUTI.
- Percentage of Patients With Composite of Microbiological Eradication and Clinical Cure in the ME Population at TOC [ Time Frame: Day 17 TOC Visit ]Microbiological eradication: urine culture showed the pathogen found at baseline at ≥10^5 CFU/mL was reduced to <10^4 CFU/mL. Clinical Cure TOC: Complete resolution or return to premorbid levels of core symptoms of cUTI and no new symptoms develop, and no use of non-study antibiotic therapy for the current cUTI. Failure TOC: Persistence of one or more core symptom of infection or reappearance of or development of new core symptoms that require alternative non-study antibiotic therapy for the current cUTI.
- Percentage of Patients With Treatment-Emergent Adverse Events (TEAEs) [ Time Frame: Up to Day 32 ]An adverse event (AE) is any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered to be drug related. An AE (also referred to as an adverse experience) can be any unfavorable and unintended sign (eg, an abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, and it does not imply any judgment about causality. Adverse events also include the exacerbation or worsening of a condition present at screening other than the index infection for which the patient was enrolled in the study. A TEAE is any AE that newly appeared, increased in frequency, or worsened in severity following initiation of study drug.
- Plasma Pharmacokinetics (PK): Area Under the Curve From 0 to 24 Hours (AUC 0-24h) [ Time Frame: Day 3 ]PK blood samples were collected on Day 3 (plus or minus 1 day) of study drug administration for the determination of plazomicin concentrations in plazomicin-treated patients.
- Plasma PK: Maximum Observed Plasma Drug Concentration (Cmax) [ Time Frame: Day 3 ]PK blood samples were collected on Day 3 (plus or minus 1 day) of study drug administration for the determination of plazomicin concentrations in plazomicin-treated patients.
- Plasma PK: Minimum Observed Plasma Drug Concentration (Cmin) [ Time Frame: Day 3 ]PK blood samples were collected on Day 3 (plus or minus 1 day) of study drug administration for the determination of plazomicin concentrations in plazomicin-treated patients.
