Title

Safety and Efficacy in Patients Treated for Hip or Knee PJI With Vancomycin and Tobramycin Joint Irrigation
A Phase 2 Multicenter Feasibility Trial to Evaluate Safety and Efficacy in Patients Treated for Hip or Knee Prosthetic Joint Infection (PJI) With Alternating Irrigation of Vancomycin Hydrochloride (HCl) and Tobramycin Sulfate in Two-Stage Exchange Arthroplasty

Study Type

Prospective, single-arm, open-label, multicenter (3 to 5 sites), interventional trial.

Primary Study Objective

The objective of the study is to determine the safety profile of local antibiotic irrigation for the treatment of PJI.

Primary Outcome Measure

The overall safety profile is characterized by assessing the incidence of adverse events (AEs), serious adverse events (SAEs), suspected adverse reactions, adverse reactions, and unexpected adverse reactions.

Follow-up

Patients will be assessed for all measures at 3 weeks, 6 weeks, 12 weeks, and 12 months from initial surgery.

Criteria

Inclusion Criteria:

Exclusion Criteria:

Late acute hematogenous infection per Tsukayama et al.

Patients with renal insufficiency/failure (serum creatinine ≥ 2.0 mg/dl)
Patients with uncontrolled diabetes, defined as: hemoglobin A1C levels > 8.0%
Patients on immunosuppressive therapy, chemotherapy for malignant disease, or glucocorticoid therapy (e.g. prednisone ≥ 10 mg/day).
Patients with immunodeficiency (e.g., splenectomy; sickle cell anemia; Stage 3 HIV; primary humoral, bone marrow, or other transplantation.)
Anticipated or potential patient relocation that may interfere with follow-up examinations
Allergy to vancomycin HCl or tobramycin sulfate (Note: prior history of Red Man's syndrome is not considered an allergy)
Patients who are pregnant or planning to become pregnant
Patients in whom negative pressure wound therapy is contraindicated
Patients infected with pathogens that are not considered susceptible to vancomycin HCl or tobramycin sulfate, as per the Investigator's opinion
Breastfeeding at screening visit
Patients who are prisoners
Participation in another clinical trial of another Investigational Drug or Investigational Device within the past 30 days
