Study arms

  • Experimental
    Ceftaroline fosamil and NXL104 (q8h)

    Drug: Ceftaroline fosamil and NXL104 (q8h) · Drug: Placebo

  • Experimental
    Ceftaroline fosamil and NXL104 (q12h)

    Drug: Ceftaroline fosamil and NXL104 (q12h) · Drug: Placebo

  • Active comparator
    Doripenem

    Drug: Doripenem · Drug: Placebo

Interventions

  • DrugCeftaroline fosamil and NXL104 (q8h)

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

    Also known as: Ceftaroline fosamil and Avibactam(NXL104) (q8h)

  • DrugCeftaroline fosamil and NXL104 (q12h)

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

    Also known as: Ceftaroline fosamil and Avibactam(NXL104) (q12h)

  • DrugDoripenem

    500 mg doripenem IV 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.

    Also known as: placebo (saline)

What researchers measure

Primary outcomes

  1. Microbiological response of Microbiologically Evaluable (ME) at Test of Cure (TOC)

    The 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)

    Time frame: 5 to 11 days after last dose of study drug

  2. Evaluate safety

    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.

    Time frame: from 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)

Secondary outcomes

  1. Clinical response in CE at Test of Cure

    The number and percentage of subjects in each treatment group classified as clinical cure Clinically Evaluable (CE) Population at TOC

    Time frame: 5 to 11 days after last dose of study drug
