Study of Ceftolozane/Tazobactam (MK-7625A) in Japanese Participants With Uncomplicated Pyelonephritis and Complicated Urinary Tract Infection (MK-7625A-014)

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.

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.

The percentage of participants that had study drug discontinued during the study due to an AE was summarized.

The per-pathogen microbiological outcome was determined for each uropathogen isolated at baseline at EOT (7 days post first dose of study drug). 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.

The per-pathogen microbiological outcome was determined for each uropathogen isolated at baseline at LFU (42 days post first dose of study drug). 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.

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. Outcomes reported as "indeterminate" were excluded. Percentage of participants with clinical response of clinical cure at TOC was summarized

The percentage of participants that met requirements for both eradication and clinical cure at TOC was summarized.

The per-pathogen microbiological outcome was determined for each uropathogen isolated at baseline. Microbiological outcome was classified as "Eradication", "Persistence" or "Indeterminate." A successful microbiological response was "Eradication" which was defined as urine culture showed the specific pathogen found at baseline at ≥10^5 colony-forming unit (CFU)/mL was reduced to <10^4 CFU/mL. If the outcome for any uropathogen was persistence (CFU/mL not reduced the result was classified as a failure. Outcomes reported as "indeterminate" were excluded. The percentage of participants that achieved eradication for each uropathogen at EOT (7 days post first dose of study drug) was summarized.
