PolyPid Announces New Publication Highlighting Potent Antibacterial Activity of D-PLEX₁₀₀ against Susceptible and Resistant Bacteria for the Prevention of Surgical Site Infections

Potent Antibacterial Efficacy of D-PLEX₁₀₀ in In-vivo and Phase 2 Clinical Studies against a Wide Range of Bacteria Tested, including Resistant Strains

D-PLEX₁₀₀ Antibacterial Activity Attributed to its Ability to Support High and Prolonged Local Antibiotic Concentration Directly at the Surgical Site

PETACH TIKVA, Israel, June 29, 2023 (GLOBE NEWSWIRE) — PolyPid Ltd. (Nasdaq: PYPD) (“PolyPid” or the “Company”), a late-stage biopharma company aiming to improve surgical outcomes, today announced a new publication highlighting the potent antibacterial activity of D-PLEX₁₀₀ and its potential as an effective prophylactic drug against the most prevalent bacteria causing surgical site infections (SSIs), including resistant strains. The paper, entitled, “Potent antibacterial activity in surgical wounds with local administration of D-PLEX₁₀₀” was recently published in the European Journal of Pharmaceutical Sciences and can be found here.

“This publication highlights the tremendous potential of D-PLEX₁₀₀ in addressing the persistent challenge of surgical site infections, especially in an era of increased multidrug-resistant bacteria” stated Dikla Czaczkes Akselbrad, PolyPid’s Chief Executive Officer. “The data showed the significant antibacterial activity of D-PLEX₁₀₀ in pre-clinical and phase 2 clinical studies against a wide range of bacteria tested, including resistant ones. D-PLEX₁₀₀’s high anti-bacterial efficacy is attributed to its ability to support high local doxycycline concentration over a prolonged period in the surgical site and confirm its prophylactic potential against a wide range of antibiotic resistant bacteria, addressing a critical need in hospital care.”

The efficacy and safety of D-PLEX₁₀₀ for the prevention of abdominal colorectal SSIs are currently being further evaluated in the SHIELD II Phase 3 clinical trial. Top-line results are expected in mid-2024.

About D-PLEX₁₀₀
D-PLEX_100, PolyPid’s lead product candidate, is designed to provide local prolonged and controlled anti-bacterial activity directly at the surgical site to prevent SSIs. Following the administration of D-PLEX₁₀₀ into the surgical site, the PLEX (Polymer-Lipid Encapsulation matriX) technology pairs with Active Pharmaceutical Ingredients, enabling a prolonged and continuous release of the broad-spectrum antibiotic doxycycline, resulting in a high local concentration of the drug for a period of 30 days for the prevention of SSIs, with additional potential to prevent SSIs caused by antibiotic-resistant bacteria at the surgical site. D-PLEX₁₀₀ received Breakthrough Therapy Designation from the U.S. FDA for the prevention of SSIs in patients undergoing elective colorectal surgery. D-PLEX₁₀₀ also received three Qualified Infectious Disease Product (QIDP) designations, and three Fast Track designations for the prevention of SSIs in patients undergoing elective colorectal surgery, post-abdominal surgery incisional infection and for the prevention of sternal wound infection post-cardiac surgery.
