Cyclic Irrigation of Vancomycin Hydrochloride and Tobramycin Sulfate in Exchange Arthroplasty

What is the Purpose of this Study?

The purpose of this study is to allow access to the experimental VT-X7 Treatment System for patients who have a periprosthetic joint infection (PJI) in their knee or hip after a previous joint replacement surgery and who do not otherwise have access to this therapy. The VT-X7 Treatment System is used to irrigate (flush with fluid to clean) the joint after surgery for the treatment of periprosthetic joint infection. The System is a combination product consisting of 2 drugs and a short-term, implantable delivery device called the VT-X7 Spacer. The 2 drugs are vancomycin hydrochloride and tobramycin sulfate, which are locally delivered to the site of infection using the short-term VT-X7 Spacer. Vancomycin hydrochloride and tobramycin sulfate are antibiotic medications that are commonly used intravenously (through the vein) or by mouth. Both antibiotics are approved by the U.S. Food and Drug Administration (FDA) for the intravenous treatment of bacterial infections. Standard-of-care treatment of PJI commonly involves this intravenous therapy, usually over many weeks. This study will use the medications to locally irrigate the joint space over a shorter period of time (7-10 days).

Eligibility

1. Planned removal of hip or knee prosthesis as part of an exchange arthroplasty, due to hip or knee PJI. The prosthesis removed may be either i) a permanent implant or, ii) a temporary spacer implanted during a resection arthroplasty.
2. Patients who have failed a prior exchange arthroplasty.
3. Signed informed consent.
4. 22 to 84 years of age (inclusive).

Inclusion Criteria:

1. Planned removal of hip or knee prosthesis as part of an exchange arthroplasty, due to hip or knee PJI. The prosthesis removed may be either i) a permanent implant or, ii) a temporary spacer implanted during a resection arthroplasty.
2. Patients who have failed a prior exchange arthroplasty.
3. Signed informed consent.
4. 22 to 84 years of age (inclusive).
5. Medical clearance for surgery.
6. Pre-enrollment diagnosis of PJI of the hip or knee per the International Consensus Meeting of Musculoskeletal Infection (ICMMI) 2018 definition of Periprosthetic Hip and Knee Infection.

Exclusion Criteria:

1. Patients who are judged by the Study Site PI to be unsuitable for the study (i.e., current medical condition that would interfere with study conduct or results or unreliable for required study follow-up).
2. Patients with bacteremia or positive bacterial blood culture in the last 30 days.
3. Patients with concurrent PJI of more than one joint.
4. Patients with ongoing active infection of an intravenous (IV) site.
5. Patients who require long-term anticoagulation or antiplatelet therapy, and for whom bridging or withholding therapy is not recommended based on the individual's clinical condition.
6. Patients with advanced renal insufficiency (i.e., chronic kidney disease (CKD) Stage 4 or 5 or patients with an estimated glomerular filtration rate (eGFR) \<30 mL/min) measured within 180 days of consent.
7. Patients on chemotherapy for malignant disease.
8. Patients on systemic glucocorticoid therapy (prednisone \>10 mg/day or equivalent).
9. Patients who are immunodeficient (e.g., splenectomy, sickle cell anemia, Stage 3 human immunodeficiency virus (HIV) infection, primary immunodeficiency disease), except patients who are immunodeficient due to immunosuppressive therapy.
10. Patients who have an allergy to vancomycin hydrochloride or tobramycin sulfate (Note: prior history of red man syndrome is not considered an allergy).
11. Patients who have an allergy to titanium, titanium alloys, polymethylmethacrylate or polyurethane.
12. Patients who are pregnant or planning to become pregnant in the next 30 days.
13. Patients with a fungal PJI as determined by one or more positive fluid and/or tissue cultures.
14. Patients who have a skeletal defect greater than 150 mm in length in the tibia or femur of the infected joint.
15. Patients who have a planned surgical procedure within 30 days of enrollment that can impact the conduct of the study.
16. Patients who are breastfeeding.
17. Patients who are incarcerated or are facing impending incarceration.
18. Patients who have been in treatment for substance abuse within the past year or referred to treatment for substance abuse within the past year.
19. Patients who will participate in another clinical study of an investigational drug or investigational device or have participated in another clinical study of an investigational drug or investigational device within the past 30 days that would interfere with the study results or the conduct of the study.
20. Patients receiving immunosuppressive drug therapy for bone marrow or another transplant.
21. Patients who receive therapy including any of the following biologic agents, which will not be withheld for a period beginning at least one dosing cycle (minimum 7 days) prior to planned surgery and ending at least 14 days following planned surgery:
Adalimumab (Humira) Tocilizumab (Actemra) Etanercept (Enbrel) Anakinra (Kineret) Golimumab (Simponi) Secukinumab (Cosentyx) Infliximab (Remicade) Ustekinumab (Stelara) Abatacept (Orencia) Tofacitinib (Xeljanz) Belimumab (Benlysta)
