Trial Outcomes & Findings for Study of Ceftolozane/Tazobactam (MK-7625A) in Japanese Participants With Uncomplicated Pyelonephritis and Complicated Urinary Tract Infection (MK-7625A-014) (NCT NCT02728089)

NCT ID: NCT02728089

Last Updated: 2019-02-05

Results Overview

The per-pathogen microbiological outcome was determined for each uropathogen isolated at baseline at TOC (14 days post first dose). Microbiological outcome was classified as "eradication", "persistence" or "indeterminate." A successful microbiological response was "eradication" which was defined as urine culture showed all uropathogens found at baseline at ≥10\^5 colony-forming unit (CFU)/mL were reduced to \<10\^4 CFU/mL. If the outcome for any uropathogen was" persistence" (CFU/mL not reduced the result was classified as unsuccessful. Participants with responses reported as "indeterminate" were excluded.

PRIMARY outcome

Timeframe: Day 14 (14 days post first dose of study drug)

Population: All participants who received at least 1 dose of study drug, had at least 1 acceptable causative uropathogen at baseline, adhered to study procedures, had a clinical response at the visit of interest within specified visit window, had an appropriately collected urine culture specimen and interpretable urine culture result at the visit of interest.

The per-pathogen microbiological outcome was determined for each uropathogen isolated at baseline at TOC (14 days post first dose). Microbiological outcome was classified as "eradication", "persistence" or "indeterminate." A successful microbiological response was "eradication" which was defined as urine culture showed all uropathogens found at baseline at ≥10\^5 colony-forming unit (CFU)/mL were reduced to \<10\^4 CFU/mL. If the outcome for any uropathogen was" persistence" (CFU/mL not reduced the result was classified as unsuccessful. Participants with responses reported as "indeterminate" were excluded.

Population: All participants who received at least 1 dose of study treatment and had follow-up data for endpoint.

An AE was defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the treatment. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, regardless of whether or not it was considered related to the medicinal product. The percentage of participants that reported at least 1 AE was summarized.

All participants had to have an evaluable clinical outcome; an indeterminate response was excluded.

The Investigator classified clinical outcome as "clinical cure", "clinical failure", or "indeterminate". A favorable clinical response is "clinical cure" defined as complete resolution of, marked improvement in (where clinical improvement was defined as a reduction in severity of all baseline signs and symptoms with worsening of none and with no requirement for additional antibiotic therapy after EOT), or return to pre-infection signs and symptoms and no use of additional or nonstudy antimicrobial therapy for the treatment of the current UTI.
