  Purpose
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.

    Clinical laboratory parameters included ALT, ALP, AST, Creatine kinase and GGT. Baseline was Day 1. Change from Baseline was calculated by subtracting Baseline values from individual post-Baseline values. Mean change from Baseline up to Late follow-up visit in ALT, ALP, AST, Creatine kinase and GGT are presented.

  • Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE) [ Time Frame: Up to 28 days post-therapy ]
    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.

  • Number of Participants With Abnormal Electrocardiogram (ECG) Findings [ Time Frame: Up to Late Follow-up Visit (21 to 28 days post-IV therapy) ]
    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.

  • Summary of Vital Signs: Mean Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) [ Time Frame: Up to Late Follow up Visit (21 to 28 days post-IV therapy) ]

  • Summary of Vital Signs- Mean Heart Rate [ Time Frame: Up to Late Follow-up Visit (21 to 28 days post-IV therapy) ]
    Vital sign measurements included heart rate. Measurements that deviated substantially from previous readings were repeated immediately. Mean heart rate is presented.

  • Summary of Vital Signs- Mean Respiration Rate [ Time Frame: Up to Late Follow-up Visit (21 to 28 days post-IV therapy) ]
    Vital sign measurements included respiratory rate. Measurements that deviated substantially from previous readings were repeated immediately. Mean respiration rate are presented.

  • Summary of Vital Signs- Mean Temperature [ Time Frame: Up to Late Follow up Visit (21 to 28 days post-IV therapy) ]
    Vital sign measurements included temperature (oral, tympanic or rectal). Measurements that deviated substantially from previous readings were repeated immediately. Temperature was assessed as normal hospital practice dictated and the maximum daily temperature was recorded in the electronic case report form (eCRF).

  • Therapeutic Response at the Test of Cure Visit [ Time Frame: Test of Cure Visit (5 to 9 days post-IV therapy) ]
    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.

  • Change From Baseline in Hematology Parameters- Hematocrit [ Time Frame: Baseline (Day 1) to Late Follow up Visit (21 to 28 days post-IV therapy) ]
    Hematology parameters included hematocrit. Baseline was Day 1. Change from Baseline was calculated by subtracting Baseline values from individual post-Baseline values. Mean change from Baseline up to Late follow-up visit in hematocrit are presented.

    Hematology parameters included MCV. Baseline was Day 1. Change from Baseline was calculated by subtracting Baseline values from individual post-Baseline values. Mean change from Baseline up to Late follow-up visit in MCV are presented.

  • Change From Baseline in Hematology Parameters- Red Blood Cell (RBC) Count and Reticulocytes [ Time Frame: Baseline (Day 1) to Late Follow up Visit (21 to 28 days post-IV therapy) ]
    Hematology parameters included RBC count and reticulocytes. Baseline was Day 1. Change from Baseline was calculated by subtracting Baseline values from individual post-Baseline values. Mean change from Baseline up to Late follow-up visit in RBC count and reticulocytes are presented.

  • Change From Baseline in Hematology Parameters- Hemoglobin and Mean Corpuscle Hemoglobin Concentration (MCHC) [ Time Frame: Baseline (Day 1) to Late Follow up Visit (21 to 28 days post-IV therapy) ]
    Hematology parameters included hemoglobin and MCHC. Baseline was Day 1. Change from Baseline was calculated by subtracting Baseline values from individual post-Baseline values. Mean change from Baseline up to Late follow-up visit in hemoglobin and MCHC are presented.

Secondary Outcome Measures:
  • Microbiological Response at the End of IV Therapy Visit, Test of Cure Visit and Late Follow-Up Visit [ Time Frame: End of IV therapy (0-24 hours post-therapy), Test of Cure Visit (5 to 9 days post-IV therapy) and Late Follow-up (21-28 days post-therapy) ]
    Microbiological response involved both microbiological success and microbiological failure. A reduction in the uropathogens in the urine culture and no growth on blood culture was termed as microbiological success. Increase in the uropathogens in the urine culture and pathogens identified in the blood culture or use of antibacterials other than study treatments were classified as microbiological failures.

  • Clinical Response at the End of IV Therapy Visit, Test of Cure Visit and Late Follow-Up Visit [ Time Frame: End of IV therapy (0-24 hours post-therapy), Test of Cure Visit (5 to 9 days post-IV therapy) and Late Follow-up (21-28 days post-therapy) ]
    Clinical response was a combination of clinical success and clinical failure. In clinical success, participants showed no signs and symptoms of pyelonephritis and lower complicated urinary tract infection and antibiotics are not used for the same. In clinical failure, there is reappearance of signs and symptoms of and lower complicated urinary tract infection and participant required antibiotics for the same.

    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.
