Study 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.
