4. Unlikely to survive at least through the duration of the study
5. Hypotension, systolic blood pressure = 90 mmHg
6. Complicated pyelonephritis with complete obstruction or known or suspected renal or perinephric abscess, emphysematous pyelonephritis,
OR
Any condition likely to require surgery to achieve cure (this does NOT include procedure to place catheters or obtain diagnosis)
7. Known or suspected urinary fungal infection
8. Uncomplicated lower urinary tract infections
9. Suspected or confirmed active prostatitis, or currently under treatment for prostatitis
10. High risk for cUTI due to Pseudomonas sp. (eg, history of prior cUTIs due to Pseudomonas, = 20 mg QD prednisone or equivalent steroid, and other risk factors as perceived by the Investigator)
11. History of renal transplantation
12. Presence of an ileal loop
13. Any history of trauma to the pelvis or urinary tract occurring within 30 days prior to consent
14. Indwelling urinary catheters present at screening which are not expected to be removed or replaced within 72 hours of randomization (eg, nephrostomy tubes, stents, urethral and suprapubic catheters).
15. Known concomitant HIV infection with CD4 counts below 200 cells/µL within six months prior to consent, or an AIDS defining diagnosis within six months prior to consent

20. Any other unstable or clinically significant concurrent medical condition (e.g., immunosuppressive therapy, chemotherapy, class IV heart or lung disease, end stage renal disease, or requiring hemodialysis) that would, in the opinion of the Investigator, jeopardize the safety of a subject and/or their compliance with the protocol

Primary Outcome(s)

Main Objective: The primary objective is to demonstrate that eravacycline is non-inferior to ertapenem in microbiological outcome in the microbiological modified intent-to-treat (micro-MITT) and microbiologically evaluable (ME) populations at the Test of Cure (TOC) visit.

For the FDA: The primary objective is to demonstrate that IV eravacycline is non-inferior to ertapenem in responder outcome (clinical cure and microbiologic success) in the microbiological intent-to-treat (micro-ITT) population at the End of IV (EOI) visit (within 1 day of the completion of IV study drug treatment) and Test of Cure (TOC) visit (defined as 14-17 days after randomization).

Primary end point(s): The primary endpoint will be the microbiologic outcome at the TOC visit in the micro-MITT and ME populations.

For the FDA: the primary endpoints of the study are the responder rates (clinical cure and microbiologic success) at the End of IV (EOI) and Test of Cure (TOC) visits in the micro-ITT population.

Timepoint(s) of evaluation of this end point: End of IV (EOI) and Test of Cure (TOC) visits

Secondary Objective: The secondary objectives of the study are:
1. To compare responder outcomes in the treatment arms at Day 5.
