Bacteriophage Therapy in First Time Chronic Prosthetic Joint Infections

Phase 1
Withdrawn
Conditions
Bacterial Infections
Prosthetic Joint Infection
Interventions
Biological: Phage Therapy
Registration Number
NCT05269121
Lead Sponsor
Adaptive Phage Therapeutics, Inc.
Brief Summary

This study will test the feasibility of a regimen of intraoperative (IO) and intravenous (IV) PhageBank™ bacteriophage therapy in conjunction with a DAIR procedure to cure chronic prosthetic joint infection (PJI) without replacement of the prosthesis.

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 1 or 2 of the following organisms: Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus lugdunensis, Streptococcus spp., Enterococcus faecium, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, and/or Klebsiella pneumoniae.

This study will compare the safety and efficacy of phage therapy in conjunction with standard of care antibiotics and a DAIR procedure.
