A Study of LBP-EC01 in the Treatment of Acute Uncomplicated UTI Caused by

Status Recruiting

Clinical Trial Summary

This is a Phase 2 superiority study of LBP-EC01, a recombinant bacteriophage cocktail, with an initial open-label 3-arm pharmacokinetic (PK) lead-in portion of 30 patients to evaluate the optimal dosing regimen to be used in the subsequent 288 patient blinded portion of the study which will be randomized 1:1 comparing LBP-EC01 + antibiotic versus placebo + antibiotic in patients with a history of prior urinary tract infection (UTI) cased by E. coli. All patients will be required to have an active acute uncomplicated UTI at baseline.

Clinical Trial Description

This study will consist of two parts. Part 1 - Dose regimen selection: An open-label, 30 patient, 3-arm PK assessment of: Arm 4 (previously 1): LBP-EC01 (approximately 2×10^12 PFU) given by IU administration on D1 and D2 and LBP-EC01 (approximately 1×10^11 PFU) IV given as a 1 milliliter (mL) bolus QD from D1 through D3 concomitantly with oral trimethoprim/sulfamethoxazole (TMP 160mg/SMX 800mg) BID from D1 through D3 (6 doses); Arm 5 (previously 2): LBP-EC01 (approximately 2×10^12 PFU) given by IU administration on D1 and D2 and LBP-EC01 (approximately 1×10^10 PFU) IV given as a 1 mL bolus QD from D1 through D3 concomitantly with oral TMP/SMX BID from D1 through D3 (6 doses); Arm 6 (previously 3): LBP-EC01 (2×10^12 PFU) given by IU administration on D1 and D2 and LBP-EC01 (approximately 1×10^12 PFU) IV given as a 100 mL IV infusion over 2 h on D1 through D3 concomitantly with oral TMP/SMX BID from D1 through D3 (6 doses). Part 2 - Efficacy, Safety, Tolerability and Pharmacokinetics: A blinded, 288 patient, 1:1 randomized evaluation of the Arm 4 dose regimen, selected from Part 1, versus placebo + antibiotic (TMP/SMX -160 mg TMP and 800 mg SMX) given orally BID on Days 1 through 3. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
