Evaluation of PLG0206 in Prevention of Recurrent Infection in Patients Undergoing Debridement, Antibiotics, and Implant Retention (DAIR) for Treatment of a Periprosthetic Joint Infection (PJI) Following Knee Arthroplasty
(RETAIN)
What this study is about
The goal of this clinical trial is to evaluate whether the experimental 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).
View original scientific description
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
