Study Details

Study Description

Brief Summary

This is a Phase 1, open-label, multi-center study to determine the pharmacokinetics and safety of intravenous Eravacycline in Children with Suspected or Confirmed Bacterial Infection. Male and Female subjects from 8 to <18 years of age who fulfill the inclusion/exclusion criteria will be enrolled in this study.

Condition or Disease Intervention/Treatment Phase
  • Drug: Eravacycline (TP-434)
Phase 1

Detailed Description

This is a Phase 1, open-label, single dose study to evaluate PK, safety, and tolerability of IV eravacycline in children with suspected or confirmed bacterial infection who are receiving systemic antibiotic therapy, other than eravacycline. The study design will allow for evaluation of PK and safety of IV eravacycline in a pediatric population at exposures predicted to be comparable to those already studied in adults. The study design is depicted in Figure 1.

Two cohorts defined by age group will be enrolled simultaneously:
  • Cohort 1: 12 to <18 years of age (adolescents)

  • Cohort 2: 8 to <12 years of age (younger children) Eravacycline will be administered as a single IV dose using the optimum dosage determined from PK-PD modeling and model-based simulations of phase 1, 2, and 3 adult data. Blood samples will be collected for PK analysis at predetermined timepoints.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Cohort 1
