Comparing Rifabutin and Rifampicin for Staphylococcal Joint Infections

Official title: Rifabutin Versus Rifampicin for Treatment of Staphylococcal Prosthetic Joint Infection Treated With Debridement, Antibiotics and Implant Retention (DAIR Strategy): a Multicenter Randomized, Open-label, Non-inferiority Trial

Run by Tourcoing Hospital · NCT04672525 · Data updated 2026-11-12

This study is testing whether rifabutin is as effective and safer than rifampicin for treating joint infections caused by staph bacteria in patients who have had surgery and are on antibiotics.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with hip or knee prosthetic joint infections treated with the DAIR strategy.

Probably not a fit

Patients with infections not caused by staphylococcal species or those who cannot tolerate either antibiotic may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to compare the effectiveness and safety of rifabutin versus rifampicin in treating prosthetic joint infections (PJIs) caused by staphylococcal bacteria. The study will involve patients who have undergone debridement and are receiving antibiotic therapy while retaining their prosthesis. The hypothesis is that rifabutin may provide similar efficacy to rifampicin but with a better safety profile, particularly regarding drug interactions and liver health. Participants will be monitored to assess the non-inferiority of rifabutin in this context.

Why it matters

Potential benefit: If successful, this study could offer a safer alternative antibiotic for patients with staphylococcal PJIs.

How similar studies have gone: While rifampicin is a standard treatment, the use of rifabutin for this specific indication is less common, making this approach relatively novel.

2. Infected with at least one of the following microorganisms:

   1. Staphylococcus aureus
   2. Coagulase-negative staphylococci
3. Microorganisms susceptible to rifampicin and at least one other antibiotic suitable for the treatment of PJI (e.g., penicillin, fluoroquinolone, (doxy/mino)cycline, oxazolidinone, cotrimoxazole, daptomycin, glycopeptide, macrolide, fusidic acid), regardless of sensitivity to methicillin.
4. Age ≥ 18 years
5. At least 2 days of appropriate (i.e., covering pathogen(s) identified in the intraoperative samples) empirical agents are needed.

11. Other drug-drug interaction that contraindicated rifampicin or rifabutin
12. Porphyria
13. Unable to take oral treatment
14. Receive empirical postoperative antibiotic treatment by rifampicin or rifabutin prior to randomization
15. Pregnancy or lactating women
16. Curator or guardianship or patient placed under judicial protection
