Study in Patients Undergoing Debridement, Antibiotics, and Implant Retention (DAIR) for Treatment of a Periprosthetic Joint Infection (PJI) Occurring After Total Knee Arthroplasty (TKA)

Purpose

The purpose of this study is to learn about the safety and effects of PLG0206 for treating periprosthetic joint infections (PJI) in conjunction with the DAIR (debridement, antibiotics and implant retention) surgical procedure for patients with periprosthetic joint infections (PJI) after total knee arthroplasty (TKA) .

Detailed Description

Peptilogics, Inc. is developing PLG0206 for the treatment of PJIs. PLG0206 is an engineered antibacterial peptide (EAP) based on naturally-occurring antimicrobial peptides (AMPs). Recent work on PLG0206 has documented that PLG0206 is a highly effective anti-biofilm agent, in addition to its established activity against planktonic staphylococcus, both in vitro and in a murine animal model of PJI. PLG0206 will be investigated in this study for treatment of PJI in conjunction with the DAIR procedure followed by the 6-week course of antimicrobial therapy that is standard-of-care (SOC) in this indication. Patients will be followed for approximately 1 year post treatment.
