Disease: Urinary Tract Infections, UTI, (NCT04191148)

Disease info:

The urinary system is the body's drainage system for removing wastes and extra water. It includes two kidneys, two ureters, a bladder, and a urethra. Urinary tract infections (UTIs) are the second most common type of infection in the body.

Symptoms of UTI include

  • Pain or burning when you urinate
  • Fever, tiredness, or shakiness
  • An urge to urinate often
  • Pressure in your lower belly
  • Urine that smells bad or looks cloudy or reddish
  • Pain in your back or side below the ribs


People of any age or sex can get UTIs, but about four times as many women get UTIs than men. You're also at higher risk if you have diabetes, need a tube to drain your bladder, or have a spinal cord injury.

Status: Completed


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 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.
