NCT07214311

Brief Summary

The goal of this clinical trial is to evaluate whether the investigational drug PLG0206 can help reduce recurrence of infection in adults who have undergone total knee replacement and are receiving a DAIR (Debridement, Antibiotics, and Implant Retention) surgical procedure to treat a Prosthetic Joint Infection (PJI). The study will also assess the safety of PLG0206 when used as an irrigation solution during the DAIR procedure. Participants will receive either PLG0206 or a placebo (an inactive substance that looks like the investigational drug), in addition to standard of care treatments. All participants will be monitored for approximately one year following their DAIR procedure.
