Use of Phage Therapy for Treatment of a Periprosthetic Joint Infection
Canada1 participantsStarted 2024-02-22
Plain-language summary
The goal of this clinical trial is to learn about the safety, tolerability and activity or efficacy of systemic intravenous and intraarticular administration of a mono-bacteriophage (phage) peparation in a patient with chronic-recalcitrant methicillin-resistant Staphylococcus epidermidis (MRSE) periprosthetic joint infection (PJI) and also to understand clinical changes pre- and post-therapy, as well as identifying adjunctive changes in biomarkers (C-reactive protein \[CRP\], erythrocyte sedimentation rate \[ESR\], and interleukin-6 \[IL-6\]) correlated with PJI.
Phage will be administered to the study participant with chronic PJI twice daily over a total duration of two weeks via two routes: a) intravenous (through vein) and b) intra-articular (through the affected joint). Phage therapy is given 4 hours after the patient receives their standard of care antibiotic therapy. The patient will remain in clinical follow-up for up to a year.1

Inclusion Criteria:
This N-of-1 Phage therapy is designed for one patient who meet the following conditions.
* willingness to provide signed and dated informed consent form to participate in the clinical study.
* severe chronic periprosthetic joint infection due to a multidrug resistant strain of S. epidermidis in which surgical source control with complete removal of implants cannot be safely achieved
* have received multiple surgical revisions with complex reconstructions and adjunctive flap coverage procedures and prolonged courses of antibiotic therapy and suffered multiple, severe antibiotic allergic reactions during initial treatment course which has lead to the use of any viable suppressive therapy impossible
* complex burden of hardware
* poor bone quality and hip instability with high associated morbidity and mortality due to the S. epidermidis infection
Exclusion Criteria:
\- below age 18 years
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
