Brief summary

This is a study in adult subjects with complicated urinary tract infection (cUTI) comparing treatment with intravenous (IV) coadministered ceftaroline fosamil and NXL104 versus treatment with IV doripenem.

Interventions

DRUGCeftaroline fosamil and NXL104 (q12h)

600 mg ceftaroline fosamil/600 mg NXL104 IV coadministered every 12 hours (q12h);

DRUGDoripenem

500 mg doripenem IV q8h;

DRUGCeftaroline fosamil and NXL104 (q8h)

600 mg ceftaroline fosamil/600 mg NXL104 IV coadministered every 8 hours (q8h);

DRUGPlacebo

On CXL-MD-02, there were (3) treatment arms (meaning a subject could be randomized to 1 of 3 possible treatment regimens). Each treatment arm contained 1 or 2 placebo doses of IV saline in order to preserve the blind.

Primary

MeasureTime frameDescription
Microbiological response of Microbiologically Evaluable (ME) at Test of Cure (TOC)5 to 11 days after last dose of study drugThe number and percentage of subjects in each treatment group recorded as having a favorable microbiological response in the ME Population at Test-of-Cure (TOC)
Evaluate safetyfrom administration of first dose of study drug to the Late -Follow -Up (LFU) visit (28 to 42 days after administration of the last dose of study drug)Evaluate the safety of coadministered IV ceftaroline fosamil and NXL104 in subjects with cUTI. Summaries of AEs, SAEs, deaths, laboratory evaluations (hematology and coagulation studies, comprehensive metabolic panel, and urinalysis), vital signs, ECGs, and physical examinations will be provided for each treatment group.
