Phase 2
Withdrawn
Conditions
Prosthetic Joint Infection
Interventions
Drug: Placebo
Registration Number
NCT05269134
Lead Sponsor
Adaptive Phage Therapeutics, Inc.
Brief Summary

This is a study designed to evaluate bacteriophage therapy in patients with chronic prosthetic joint infections.

Detailed Description

This is a study designed to evaluate bacteriophage therapy in patients with chronic prosthetic joint infections of the hip or knee caused by at least 1 of the following organisms: Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus lugdunensis, Streptococcus spp., Enterococcus faecium, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, or Klebsiella pneumoniae.

This study will compare the safety and efficacy of DAIR procedure + Phage Therapy + Antibiotics versus DAIR procedure + Placebo + Antibiotics.
