Brief Summary

Rifampicin, is key in the treatment of staphylococcal PJIs. Rifabutin has a better profile of tolerance than rifampicin regarding the risk of interaction with concomitant medications and liver disorders. The hypothesis is that rifabutin may be an alternative antibiotic option as efficient as rifampicin for the treatment of staphylococcal PJIs, with a better safety profile. The investigator aim to demonstrate the non-inferiority of rifabutin as compared with rifampicin prescribed in combination treatment for PJIs.

Outcome Measures

Primary Outcomes (1)

  • Treatment failure

    Treatment failure defined as one of following events: * The need for any further surgical procedure - i.e. implants removal, implants exchange or amputation; * And/or PJI related death; * And/or use of suppressive antibiotic therapy that was not planned before randomization

    At one year

Secondary Outcomes (7)

  • Occurrence of serious adverse events (SAEs), including death (i.e. all cause)

    At the end of 12 weeks duration of antibiotic treatment planned

  • Occurrence of any adverse event that could be related to rifampicin or rifabutin

    At the end of 12 weeks duration of antibiotic treatment planned

  • Proportion of patients from each arm who will complete the 12-week duration of rifampicin/rifabutin treatment, early termination of the planned 12 weeks' period of antibiotics

    At the end of 12 weeks duration of antibiotic treatment planned

  • Adherence to antibiotics regimen

    At the end of 12 weeks duration of antibiotic treatment planned

  • Quality of life, as evaluated by EQ 5D 3L questionnaire

    At the end of the study follow up, an average of 24 months

  • +2 more secondary outcomes

Study Arms (2)

RIFAMPICIN

ACTIVE COMPARATOR

Patient with staphylococcal PJI, treated with DAIR strategy, and randomized in the control group will receive rifampicin in association with another antibiotic except rifabutin, as-per recommendations for 12 weeks.

Drug: Rifampicin

RIFABUTIN

EXPERIMENTAL

Patient with staphylococcal PJI treated with DAIR strategy, and randomized in the experimental group, will receive rifabutin in association with another antibiotic except rifampicin, as-per recommendations for 12 weeks.

Drug: Rifabutin

Interventions

2 tablets of 150 mg per day rifabutin tablet daily for 12 weeks in 1 administration with a companion treatment

RIFABUTIN

10 mg/kg per day (range 600 mg to 1,200 mg) rifampicin tablet in 1 daily dose for 12 weeks with a companion treatment

RIFAMPICIN

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Hip or knee Prosthetic joint infection treated by debridement, antibiotic therapy initiation and retention of prothesis (DAIR strategy)
  • Infected with at least one of the following microorganisms:
  • Staphylococcus aureus
  • Coagulase-negative staphylococci
  • 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.
  • Age ≥ 18 years
  • At least 2 days of appropriate (i.e., covering pathogen(s) identified in the intraoperative samples) empirical agents are needed. Pre-randomization antimicrobial therapy could be: flucloxacillin, oxacillin, vancomycin, daptomycin. β-lactam plus β-lactamase-inhibitors (e.g. ampicillin+sulbactam, piperacillin+tazobactam), cephalosporins (except ceftazidime), carbapenems, teicoplanin, ceftaroline, ceftobiprole.
  • Signed Inform consent
  • Patient having the rights to French social insurance
  • For women of childbearing potential i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile and excluding oestroprogestative-based contraception, any effective contraceptive: vasectomy (for men), intrauterine device copper, feminine sterilization, condom, sexual abstinence is required. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause

You may not qualify if:

  • Suspicion of reduce absorption of oral treatment due to abdominal disorder Known or suspected malabsorption (imperfect absorption of food material by the small intestine)
  • Polymicrobial infection due to other than staphylococcus species susceptible to rifampicin
  • Known or suspected allergy to rifabutin and/or rifampicin
  • Diagnosis of endocarditis associated to PJI
  • Renal transplant or Chronic kidney disease with an eGFR of less than 30ml/min/1.73m²
  • Other Solid Organ Transplant
  • Liver cirrhosis, Child-Pugh score C
  • Any other concomitant infection which required a prolonged course of intravenous antibiotic therapy
  • Oestroprogestative-based contraception
  • Oral anticoagulant drugs
  • Other drug-drug interaction that contraindicated rifampicin or rifabutin
  • Porphyria
  • Unable to take oral treatment
  • Receive empirical postoperative antibiotic treatment by rifampicin or rifabutin prior to randomization
  • Pregnancy or lactating women
  • +2 more criteria
