Phage therapy takes on superbug UTIs in new trial

NCT ID NCT05488340

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new treatment called LBP-EC01, which uses specially designed viruses (bacteriophages) to attack drug-resistant E. coli bacteria that cause urinary tract infections (UTIs). About 318 adults with a history of UTIs and a current infection will receive either LBP-EC01 plus an antibiotic or a placebo plus the antibiotic. The goal is to see if adding the phages helps clear the infection and symptoms better than the antibiotic alone.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
LBP-EC01 (a cocktail of viruses that attack bacteria, called bacteriophages) plus an antibiotic (trimethoprim/sulfamethoxazole)
What this could lead to
If it works, this could offer a new treatment option for people with hard-to-treat urinary tract infections caused by drug-resistant E. coli bacteria.
What could go wrong
This is a phase 2 trial, so it's still early. The treatment may not work better than antibiotics alone, and there could be side effects or immune reactions to the phages.
