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

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.
