Localized Antibiotic Delivery Shows Promise in Preventing Surgical Infections: PolyPid's D-PLEX₁₀₀ Earns Top Honors

November 06, 2025 – In a significant step forward for infection control, PolyPid Ltd. has been awarded the ‘Therapeutics Solution of the Year’ by BioTech Breakthrough for its lead product candidate, D-PLEX₁₀₀. The innovative therapy utilizes a unique localized antibiotic delivery system, demonstrating a substantial reduction in surgical site infections (SSIs) during Phase 3 clinical trials. This breakthrough could drastically alter how SSIs – a major concern for patients and healthcare systems alike – are prevented and treated.

SSIs represent a significant burden on healthcare, accounting for an estimated 20-31% of all hospital-acquired infections. These infections not only prolong hospital stays and increase healthcare costs but also lead to significant patient morbidity and mortality. Traditional methods of SSI prevention rely heavily on systemic antibiotics, which contribute to the growing problem of antibiotic resistance and carry their own risks.

“The current approach to infection control often feels reactive,” explains a healthcare professional specializing in infectious disease, who requested anonymity. “A proactive, localized solution like D-PLEX₁₀₀ addresses the infection at the source, potentially reducing the need for broad-spectrum antibiotics and minimizing the risk of resistance.”

How D-PLEX₁₀₀ Works: A New Approach to Infection Prevention

D-PLEX₁₀₀ employs PolyPid’s proprietary PLEX (Polymer-Encapsulated Localized Extraction) technology. This innovative platform encapsulates a potent antibiotic within a biodegradable polymer matrix. This matrix is then applied directly to the surgical site during closure. The polymer slowly releases the antibiotic over a defined period, creating a high concentration of the drug precisely where it’s needed – at the wound site.

The Phase 3 clinical trial, data from which remains confidential pending full publication, demonstrated a 58% reduction in SSIs compared to standard care in patients undergoing colorectal surgery. This significant reduction highlights the potential of localized antibiotic delivery to drastically improve patient outcomes.

Beyond Traditional Methods: Addressing the Rise of Antibiotic Resistance

The increasing prevalence of antibiotic-resistant bacteria is a global health crisis. The overuse and misuse of antibiotics have driven the evolution of resistant strains, making infections harder to treat. Localized antibiotic delivery, by concentrating the drug at the site of infection, may reduce the overall antibiotic load on the patient and minimize the selective pressure driving resistance.

“The beauty of this approach is that it's targeted,” says a biomedical engineer specializing in drug delivery systems. “By delivering a high concentration of the antibiotic directly to the wound, you potentially reduce the systemic exposure and the opportunity for bacteria to develop resistance.”

Financial Implications and Market Potential

The global surgical site infection prevention market is projected to grow. The demand for effective and innovative SSI prevention solutions is driven by the increasing number of surgical procedures performed worldwide and the growing awareness of the economic burden of SSIs.

PolyPid’s success could significantly disrupt this market. The company is preparing to submit a New Drug Application (NDA) to the FDA in early 2026. The Breakthrough Therapy Designation and Fast Track status granted by the FDA could expedite the review process.

“If approved, D-PLEX₁₀₀ could become a standard of care for high-risk surgical procedures,” says a financial analyst specializing in the biotechnology sector. “The potential revenue streams for PolyPid are substantial, and the company is well-positioned to capitalize on the growing demand for effective SSI prevention solutions.”

Challenges and Future Directions

Despite the promising results, challenges remain. Further research is needed to evaluate the long-term efficacy and safety of D-PLEX₁₀₀ and to determine its effectiveness in a broader range of surgical procedures. Manufacturing scalability and cost-effectiveness are also important considerations.

PolyPid is also exploring the potential of its PLEX technology to deliver other therapeutic agents, such as anti-inflammatory drugs and growth factors, to promote wound healing and reduce complications. The company’s innovative platform could pave the way for a new generation of localized therapies that address a wide range of medical conditions.

The development of D-PLEX₁₀₀ represents a significant step forward in the fight against surgical site infections. By combining innovative technology with a targeted approach to infection prevention, PolyPid is poised to make a lasting impact on patient care and healthcare systems worldwide.
