Revolutionary Hip and Knee Prosthesis Infection Treatment: Peptilogics’ RETAIN Trial Could Reduce Repeat Surgeries
For patients who undergo hip or knee replacement surgery—procedures performed more than 5 million times annually in the U.S. And Europe alone—postoperative infections remain a devastating complication. Now, a groundbreaking clinical trial at the University of Cincinnati (UC) may offer new hope: an investigational peptide-based therapy designed to eliminate biofilm, the stubborn bacterial layer that resists antibiotics and immune responses, often forcing patients into painful, costly repeat surgeries.
The trial, led by T. Toan Le, MD, professor in UC’s Department of Orthopaedic Surgery, marks the first human testing of Peptilogics’ RETAIN (Retention of Prosthetic Joints) protocol. The approach targets prosthetic joint infections (PJI), which affect 2% to 3% of joint replacement patients—ranging from early postoperative infections to chronic cases years later. Without effective treatment, these infections can lead to joint failure, severe pain, and systemic illness.
“Biofilm is the root cause of medical device-related infections, and no approved therapy has ever been designed to target it,” said Jonathan Steckbeck, PhD, CEO of Peptilogics, a surgical therapeutics company specializing in medical device-related infections (MDRI). The current standard of care—a two-stage revision surgery involving removal of the infected prosthesis, temporary spacer insertion, and later reimplantation—carries a 25% failure rate and exposes patients to additional surgical risks.
How the RETAIN Trial Works: A Biofilm-Focused Approach
The RETAIN protocol combines debridement (surgical cleaning of the infected site) with a novel peptide solution developed by Peptilogics. After debridement, the peptide solution is applied directly to the prosthetic joint, where it disrupts biofilm formation and bacterial adhesion. Unlike traditional antibiotics, which often fail against biofilm-encased bacteria, peptides can penetrate and disrupt these protective layers.
“The window for debridement, antibiotics, and implant retention (DAIR) is limited to about two weeks after symptoms appear or within the first month of surgery,” Le explained. Symptoms of PJI include persistent pain, joint swelling, warmth, and drainage. If untreated, infections can spread, leading to sepsis or chronic disability.
Peptilogics’ approach aims to preserve the original prosthesis in eligible patients, avoiding the trauma and costs of two-stage revisions. Early results from animal studies and preclinical trials have shown promise, but the UC-led trial will be the first to test safety and efficacy in humans.
Why This Matters: The Burden of Prosthetic Joint Infections
PJIs impose a heavy human and economic toll. According to the CDC, complications from joint replacements result in hundreds of thousands of additional surgeries annually in the U.S. Alone. The financial burden is staggering: a single revision surgery can cost $50,000–$100,000, not including lost wages or long-term rehabilitation.
For patients, the stakes are personal. “Many of our patients are elderly or have chronic conditions,” said Le. “A second surgery is a significant risk, especially for those with limited mobility or comorbidities. This trial offers a potential alternative that could improve outcomes and quality of life.”
Next Steps: When Will Patients See Results?
The UC trial is currently enrolling participants, with initial results expected in 2027–2028, pending regulatory approval. If successful, Peptilogics plans to seek FDA clearance for the peptide solution as a first-in-class treatment for PJI. The company is also exploring applications for other medical device-related infections, including catheter-associated infections and surgical site infections.
For now, patients with suspected PJI should seek prompt evaluation by an orthopedic specialist. Early intervention—within the two-week DAIR window—maximizes the chances of retaining the prosthesis without infection.
Key Takeaways
- Biofilm is the primary obstacle in treating prosthetic joint infections, as it shields bacteria from antibiotics and the immune system.
- The RETAIN trial at UC is testing a peptide-based therapy to disrupt biofilm and preserve the original prosthesis, avoiding costly two-stage revisions.
- Current treatment options carry a 25% failure rate, highlighting the unmet need for new therapies.
- PJIs affect 2%–3% of joint replacement patients, with 5 million procedures performed annually in the U.S. And Europe.
- Results are expected in 2027–2028, with potential FDA approval to follow.
As the trial progresses, patients and clinicians alike will watch closely. For now, the promise of a revolutionary—in the sense of both groundbreaking innovation and patient-centered care—remains within reach.
