Safety, Tolerability, and PK of LBP-EC01 in Patients With Lower Urinary Tract Colonization Caused by E. Coli

Urinary Tract Infections Clinical Trial

Official title: A Multi-Center Randomized, Double-Blind Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of LBP-EC01 in Patients With Lower Urinary Tract Colonization Caused by E. Coli

Status Completed

Clinical Trial Summary

Study LBx-1001 is a multi-center randomized, double-blind study to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of LBP-EC01 in patients with indwelling urinary catheters, or requiring intermittent catheterization, and/or patients with asymptomatic bacteriuria caused by Escherichia coli (E. coli). This study population has been selected because LBP-EC01 is a phage cocktail where active bacterial host engagement is required to allow for amplification of the phage and evaluation of the safety and PK of the phage cocktail. Eligible patients will require confirmation of colonization with a urine sample taken within 10 days of randomization that cultures contain ≥10^3 E. coli colony forming unit (CFU)/mL, without the patient having clinical signs or symptoms of an active urinary tract infection (UTI) requiring antibiotic treatment. Patients should have E. coli as the primary colonizing bacteria and must not have a secondary bacterial colonization at levels equal to or greater than that seen from E. coli.

Clinical Trial Description

Approximately 30 patients 18 years of age or older with a history of urinary tract infection or colonization caused by E. coli who have indwelling urinary catheters, or who require intermittent catheterization, and/or patients with asymptomatic bacteriuria caused by E. coli colonization (≥10^3 CFU/mL) on microbiological diagnosis, without clinical signs or symptoms of infection requiring antibiotic treatment will be enrolled. Patients will be screened for presence of E. coli colonization (≥10^3 CFU/mL) prior to randomization and evaluated for potential bacterial susceptibility to LBP-EC01.

Secondary Objective: To evaluate the pharmacodynamics (PD) of LBP-EC01. Exploratory Objective: To explore the influence of LBP-EC01 on the urinary tract microbiota. ;
