Brief Summary
This study is being conducted to evaluate the safety, efficacy (clinical and microbiological), pharmacokinetics/pharmacodynamics of GSK2251052 and to assess whether it would be a suitable antibiotic for the treatment for febrile lower cUTI and pyelonephritis(complicated and uncomplicated). GSK2251052 will be compared to imipenem-cilastatin, which is an antibiotic commonly used to treat serious cUTI infections. GSK2251052 has a spectrum of microbiological activity that includes pathogens responsible for cUTI.

Baseline (Day 1) to Late Follow up Visit (21 to 28 days post-IV therapy)
Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE)
AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse or misuse. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant.
Up to 28 days post-therapy
Number of Participants With Abnormal Electrocardiogram (ECG) Findings
Twelve lead ECGs were obtained during the study using an ECG machine that automatically measured PR, QRS, QT, and QT corrected by Bazett's formula (QTcB), QT corrected by Fridericia's formula (QTcF) intervals. Twelve lead ECGs were performed with the participant in a semi-supine position having rested in this position for at least 10 minutes beforehand. Measurements that deviated substantially from previous readings were repeated immediately. Three measurements were taken at pre-dose on Day 1 at least 5 min apart. One additional ECG measurement was taken after completion of the first infusion of study medication. Two ECG measurements (pre and post-1st infusion of the day) were taken on Day 4 while the participant was on IV therapy. When there was an abnormal finding, two more were taken and the mean PR interval, QRS duration, QT interval and QTcB were calculated from automated ECG readings. One ECG measurement was taken at the early safety follow-up visit.
Up to Late Follow-up Visit (21 to 28 days post-IV therapy)
Summary of Vital Signs: Mean Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP)

Summary of Vital Signs- Mean Temperature
Vital sign measurements included temperature (oral, tympanic or rectal). Measurements that deviated substantially from previous readings were repeated immediately.

Up to Late Follow up Visit (21 to 28 days post-IV therapy)
Therapeutic Response at the Test of Cure Visit
The therapeutic response was the combination of a participant's clinical and microbiological response. It was assessed at the Test of Cure visit in participants who have a qualifying Gram-negative uropathogen at Baseline and have had a minimum of 5 days of IV therapy. Therapeutic response was a measure of the overall efficacy response, and a therapeutic success referred to participants who have been deemed both a 'clinical success' and a 'microbiological success'. All other combinations (other than 'clinical success' + 'microbiological success') were deemed failures for therapeutic response.
Test of Cure Visit (5 to 9 days post-IV therapy)
