Study Details

Study Description

Brief Summary

This is a phase 3, randomized, double-blind, double-dummy, multicenter, prospective study to assess the efficacy and safety of eravacycline compared with levofloxacin in participants with complicated urinary tract infections (cUTI).

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

This study began with a 3-arm Lead-in portion to determine the oral (PO) dosing (200 or 250 milligrams [mg]) of eravacycline to be used with intravenously (IV) administered eravacycline for the Pivotal portion (2 arms). A PO dose of 200 mg was selected based on the unblinded Lead-in analysis.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Eravacycline

Eravacycline was administered IV at a dose of 1.5 mg per kilogram (kg) of body weight every 24 hours (q24h). At minimum, the first 3 doses were administered IV. After an IV-to-PO transition, provided adequate clinical improvement, participants were administered 200 mg PO twice a day for a total therapy of 7 dosing cycles.

Drug: Eravacycline
Other Names:
  • TP-434
  • Active Comparator: Levofloxacin

    Levofloxacin (750 mg) was administered IV q24h. At minimum, the first 3 doses were administered IV. After an IV-to-PO transition, provided adequate clinical improvement, participants were administered 750 mg PO once a day for a total therapy of 7 dosing cycles.

    Drug: Levofloxacin

  • Levaquin
  • Outcome Measures

    Primary Outcome Measures

    1. Participants In The Microbiological Intent-To-Treat (Micro-ITT) Population With A Responder Outcome At The Post-Treatment (PT) Visit [PT Visit]

      This was the primary outcome measure for the Food and Drug Administration (FDA). The primary objective was to demonstrate the non-inferiority (NI) of eravacycline to levofloxacin in responder outcome, which was derived from both clinical and microbiological responses, in the micro-ITT population. Clinical responses were either cure, failure, or indeterminate/missing; microbiological responses were characterized programmatically as either success, failure, or indeterminate/missing. Clinical cure was defined as complete resolution or significant improvement of signs or symptoms of the infection; microbiological success was a reduction of the baseline pathogen(s) to <10^4 colony-forming units/milliliter (CFU/mL). An outcome of Responder required a clinical response of cure and a microbiological response of success. Any other combination of the clinical and microbiological responses was considered either Non-responder or Indeterminate.

    Secondary Outcome Measures

    1. Participants In The Microbiological Modified ITT (Micro-MITT) Population With A Microbiological Response [PT Visit]

      This outcome measure (FDA and the European Medicines Agency [EMA]) compared the microbiological responses of eravacycline to levofloxacin for both treatment groups in the micro-MITT population. Responses were success, failure, or indeterminate/missing. Success was considered a reduction of the baseline pathogen(s) to <10^4 CFU/mL. Failure required blood cultures at or beyond end of therapy (EOT) to be positive for baseline pathogen(s), or urine culture to grow ≥10^4 CFU/mL of the baseline pathogen(s). Indeterminate/missing indicated no interpretable culture data available.

    2. Participants In The Microbiologically Evaluable (ME) Population With A Microbiological Response [PT Visit]

      This outcome measure (FDA and EMA) compared the microbiological responses of eravacycline to levofloxacin for both treatment groups in the ME population. Responses were either success or failure. Indeterminate/missing responses were not included. Success was considered a reduction of the baseline pathogen(s) to <10^4 CFU/mL. Failure required blood cultures at or beyond EOT to be positive for baseline pathogen(s), or urine culture to grow ≥10^4 CFU/mL of the baseline pathogen(s). Indeterminate/missing indicated no interpretable culture data available. Populations: ME, all micro-ITT and clinically-evaluable (CE) participants with a suitable urine specimen and an interpretable urine culture; micro-ITT, all participants with ≥1 baseline bacterial pathogen from a urine or blood culture that caused a UTI against which eravacycline had expected antibacterial activity; ITT, all randomized participants, regardless of receiving study drug or not.

    Statistical Analysis Overview Comparison Group Selection Eravacycline, Levofloxacin
    Comments For the FDA, an NI margin of 10% was used, which was based on historical data regarding the treatment effect of antibiotics. A 10% NI margin for the Responder outcome is robust and can sufficiently confirm a clinically meaningful treatment effect of eravacycline in the treatment of cUTI.
    Type of Statistical Test Non-Inferiority
    Comments The NI test was based on the lower limit of the 2-sided 95% confidence interval (CI), using the method proposed without stratification by Miettinen and Nurminen. If the lower limit of the 95% CI for the difference in Responder (clinical cure and microbiologic success) rates in the micro-ITT population exceeded -10%, then the null hypothesis was rejected and the NI of eravacycline to levofloxacin was declared.

    Adverse Events

    Time Frame The time frame for adverse event reporting was from the first dose of study drug through 30 days after the last dose of study drug or the late post-treatment visit (whichever was later).
    Adverse Event Reporting Description The safety population was all randomized subjects who receive any amount of study drug. All safety analyses were conducted in this population and are presented by treatment actually received (not as randomized). One subject was randomized to levofloxacin but received eravacycline, therefore Eravacycline N = 455; Levofloxacin N= 450
