Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This is a pilot, randomized, non-comparative, double-blind study in patients with knee or hip prosthetic joint infection (PJI) due to Staphylococcus aureus, with the indication of DAIR and Suppressive Antibiotics Therapy (SAT). A stratification will be performed on the affected area of arthroplasty: knee or hip and on study site.
Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Investigators
All persons will be blinded, except the pharmacist will be unmasking.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Bacteriophages arm

1 mL (PP1493 or PP1815) or 2 mL (PP1493 and PP1815) of suspension of bacteriophages diluted in solution of NaCl 0,9% at the end of DAIR procedure.

Group Type EXPERIMENTAL

Anti-Staphylococcus aureus Bacteriophages

Intervention Type BIOLOGICAL

Single intra-articular injection

Control Arm

One local administration of NaCl 0,9% solution is administered at the end of the DAIR procedure.

Group Type PLACEBO_COMPARATOR

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male or female ≥ 18 years
2. Staphylococcus aureus monomicrobial knee or hip PJI ˃3 months after prosthesis implantation with clinical signs of infection and with indication of DAIR with direct closure and Suppressive Antibiotics Therapy (SAT)
3. Staphylococcus aureus only in joint fluid within 6 months before randomization or in case of relapse of infection under antibiotics therapy after a DAIR performed within 6 months before pre-inclusion visit
4. Without preoperative diagnosis of superinfection due to another pathogen
5. Phagogram displaying the susceptibility of the strain to at least one of the phages.
6. Patient with a life expectancy of 2 years and more as determined by the principal investigator
7. Females of childbearing potential/Sexually active males with partner of childbearing potential: commitment to consistently and correctly use an acceptable method of birth control (oral, transdermal, systemic or implant contraception birth control, intrauterine devices) for 1 month after the last study drug administration
8. Females of non-childbearing potential: either surgically sterilized or at least 1 year postmenopausal (amenorrhea duration at least 12 months)
9. Negative pregnancy test

Exclusion Criteria

1. Early Staphylococcus aureus Prosthesis Joint infection (˂3months after the prosthesis implantation)
2. Other germ found in culture of joint fluid sample
3. Phagogram displaying no susceptibility of the strain to anti-Staphylococcus aureus bacteriophages
4. Patients with ASA score ≥ 4
5. Severe sepsis or Septic shock or hemodynamic instability
6. Patients with an indication to prosthesis replacement or amputation
7. Immunosuppressed patients
8. ALT or AST \> 5 x ULN, creatinine \> 1.53 mg/dl in men and \> 1.24 mg/dl in women
9. Known allergic reactions to components of phages products
10. Medical history which in the opinion of the investigator would mean that the patient is unsuitable for participation in the study
11. Patients who are pregnant or breastfeeding. Patients should not be enrolled if they plan to become pregnant during the treatment period and 1 month after the last administration of study drug
12. Women/Men refusing to use an effective contraception during 1 month after the last administration of study drug.
