Study summary

This is a Phase III, randomized, double-blind, multicenter, non-inferiority study to evaluate the efficacy, safety, and tolerability of FEP-TAZ vs. meropenem in the treatment of hospitalized adults with cUTI or AP.

Read the detailed description

Approximately 1004 hospitalized adult subjects (≥18 years of age) diagnosed with cUTI or AP will be enrolled in the study. The diagnosis of cUTI or AP will be based on a combination of clinical symptoms and signs plus the presence of pyuria

Subjects will be randomized in a 1:1 ratio according to an Interactive Response Technology (IRT) electronic system to receive either FEP-TAZ 4 g (2 g cefepime + 2 g tazobactam) IV every eight hours (q8h) or meropenem 1 g IV q8h. FEP-TAZ will be administered as 2 consecutive infusions of 2 g (1 g cefepime + 1 g tazobactam)

Inclusion criteria

Meet the following clinical criteria for either cUTI or AP:

A. cUTI:

  1. Have at least TWO of the following new-onset or worsening symptoms or signs:

    Fever (oral, tympanic, or rectal temperature >38°C [>100.4°F]), which must be observed and documented by a health care provider Nausea or vomiting Dysuria, increased urinary frequency, or urinary urgency Lower abdominal, suprapubic, or pelvic pain

  2. Have at least ONE complicating factor

B. AP, defined as acute flank pain (onset within 7 days prior to randomization) or costovertebral angle tenderness on physical examination, plus at least ONE of the following new-onset or worsening symptoms or signs:

  1. Evidence of pyuria within 48 h prior to randomization,

Exclusion criteria

Exclusion Criteria:

  1. Known or suspected disease or condition that, in the opinion of the investigator, may confound the assessment of efficacy.
  2. Receipt of potentially-effective systemic antibacterial therapy within 72 h prior to randomization
  3. Rapidly progressive or terminal illness with a high risk of mortality due to any cause, including but not limited to acute hepatic failure, respiratory failure, or septic shock, such that the subject is unlikely to survive the study period

What researchers measure

Primary outcomes

  1. Percentage of subjects with overall success at Day 5

    Overall success is defined as complete resolution (or return to premorbid state) of the cUTI or AP symptoms that were present at screening, except flank pain (if present), which should show at least one grade improvement and no new cUTI or AP symptoms together with microbiologic eradication of the bacterial pathogen found at study entry (reduced to \<1000 colony forming units or CFU/mL)

    Time frame: Day 5

  2. Percentage of subjects with overall success at Test-of-Cure

    Overall success is defined as complete resolution1 (or return to premorbid state) of the cUTI or AP symptoms that were present at Screening and no new cUTI or AP symptoms together with microbiologic eradication of the bacterial pathogen found at study entry (reduced to \<1000 colony forming units or CFU/mL)

    Time frame: Test Of Cure Visit (Day 17 ± 2 days)

  3. Percentage of subjects with Treatment-Emergent Adverse Events (TEAE)

    Collection of number of adverse events.

    Time frame: Day 1 to the end of study Late Follow-Up visit (LFU) (26 ± 2 days)
