cUTI Clinical trial assessment timeline: Fetroja vs imipenem/cilastatin primary efficacy endpoint—composite of clinical response and microbiological eradication 7 days post therapy ± 2 days
Assessments:
Day 1 (Baseline)
Day 4 (Early assessment [±1 day])

In vitro activity does not necessarily correlate with clinical efficacy.

  • Non-inferiority study in patients with cUTI ± pyelonephritis (N=448)1,2
  • Randomized 2:1 to receive Fetroja (n=300) or imipenem/cilastatin (n=148) for 7-14 days1*
    • High dosage of imipenem/cilastatin used to allow for inclusion of patients with Pseudomonas aeruginosa infection2
    • Carbapenem-resistant pathogens excluded as ethical necessity due to carbapenem comparator2
  • Study was designed to capture a complicated patient population with comorbidities who are at greater risk of multidrug-resistant Gram-negative infections2
    • Allowed immunosuppressed patients, including renal transplant2
    • Limited patients with acute uncomplicated pyelonephritis to 30% maximum2
    • Step-down to oral therapy not permitted1
*
Dosages used were Fetroja 2 grams every 8 hours (infused over 1 hour), imipenem/cilastatin 1 gram/1 gram every 8 hours (infused over 1 hour).1
Recommended dosing of Fetroja is 2 grams every 8 hours by intravenous (IV) infusion over 3 hours in patients with creatinine clearance (CLcr) ≥60 to <120 mL/min.1
q8h=every 8 hours.

Primary endpoint

Primary endpointa: Composite clinical responseb and microbiological eradicationc at TOC1,2

Fetroja 72.6 % (n=183/252); Imipenem/cilastatin 54.6% (n=65/119); Treatment difference 18.6% (95% CI, 8.2, 28.9) P=0.0004

a
Microbiological intent-to-treat (micro-ITT) population, which included all patients who received at least a single dose of study medication and had at least 1 baseline Gram-negative uropathogen.1
b
Clinical response defined as resolution or improvement of cUTI symptoms and no new symptoms assessed by the investigator.1
c
Microbiological eradication defined as all Gram-negative uropathogens found at baseline at ≥105 CFU/mL were reduced to <104 CFU/mL.1

CI=confidence interval; TOC=test of cure.
