E.5 End points |
E.5.1 | Primary end point(s) |
A patient will be defined as a responder at Day 21 (± 1day; TOC) if the following criteria are met:
• The patient is alive
• Resolution of dysuria, urinary frequency, urinary urgency, suprapubic pain, and flank pain or pelvic pain if present at trial entry and no new symptoms per the patient’s questionnaire
- Baseline symptoms associated with anatomic abnormalities that predispose to cUTI (e.g., symptoms associated with the presence of an indwelling urinary catheter) do not need to be resolved.
• The patient has received no rescue therapy for cUTI
- If an antibiotic is given for other reasons then the patient will not be considered a non-responder for cUTI
• The bacterial pathogen found at ≥10*5 CFU/mL in the trial entry urine culture is reduce to <10*3 CFU/mL in the urine culture taken at the specified study visit and the blood culture is eradicated if one was present at baseline.
All other patients will be considered non-responders unless data are unavailable to determine if the patient is a responder or non-responder. In this case, the patient will be considered as having an indeterminate response. Deaths not due to cUTI will also be considered indeterminate. Patients with an indeterminate response are included in the denominator for determination of the response rate in the ITT populations. |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Microbiologic Response is assessed at Day 21 (± 1day; TOC) using the definitions listed below:
Eradication:
A urine culture taken within 48 hours prior to randomization (baseline) and compared with the culture from the Day 5 visit, Day 10 (± 1 day; or Day 11-14 (± 1 day) for patients with bacteremia at Baseline) visit, or Day 21 (± 1day; TOC) visit showed that the urine culture obtained at the relevant visit demonstrated <103 CFU/mL of the original uropathogen. For patients with bacteremia at Baseline, the follow-up repeat blood cultures are sterile.
Persistence:
A uropathogen present at baseline grew at ≥103 CFU/mL at the time-point of analysis, i.e. Day 5, Day 10 (± 1 day; or Day 11-14 (± 1 day) for patients with bacteremia at Baseline), or Day 21 (± 1day; TOC). For patients with bacteremia at Baseline, follow-up blood cultures after 72 hours of treatment show growth of baseline pathogen.
Persistence with increasing MIC:
A urine culture taken after at least 2 full days of treatment grew ≥103 CFU/mL of the original uropathogen species and displayed ≥4-fold higher MIC to study drug therapy after treatment with study therapy at Day 5, Day 10 (± 1 day; or Day 11-14 (± 1 day) for patients with bacteremia at Baseline), or Day 21 (± 1day; TOC) respectively. For patients with bacteremia at Baseline, follow-up blood cultures after 72 hours of treatment show growth of baseline pathogen and displayed ≥4-fold higher MIC to study drug therapy.
Indeterminate:
Patient was lost to follow-up or an assessment was not undertaken such that no urine culture was obtained; culture is contaminated or culture results could not be interpreted for any reason, at either the Day 5, Day 10 (± 1 day; or Day 11-14 (± 1 day) for patients with bacteremia at Baseline), or the Day 21 (± 1day; TOC) visit. |
