PolyPid's D-PLEX₁₀₀ Wins BioTech Breakthrough Award for "Therapeutics Solution of the Year"

PETACH TIKVA, Israel, Nov. 06, 2025 (GLOBE NEWSWIRE) --PolyPid Ltd.(Nasdaq: PYPD) ("PolyPid" or the "Company"), a late-stage biopharma company focused on improving surgical outcomes, today announced that D-PLEX₁₀₀, the company’s lead candidate, has been named "Therapeutics Solution of the Year" byBioTech Breakthrough, a leading independent market intelligence organization which evaluates and recognizes standout life sciences and biotechnology companies, products and services around the globe.

D-PLEX₁₀₀, powered by PolyPid’s proprietary PLEX (Polymer-Lipid Encapsulation matriX) technology is designed to prevent surgical site infections (SSIs) with extended, localized antibiotic delivery directly at the surgical site. Administered during the surgery, D-PLEX₁₀₀ delivers continuous, targeted release of doxycycline for 30 days, protecting patients during the period of highest vulnerability to infection.

"PolyPid is setting a new standard for SSI prevention. These infections remain among the most common and costly post-operative complications, causing extended hospital stays and higher morbidity rates. Standard antibiotics often fail to reach surgical sites due to disrupted blood supply," said Bryan Vaughn, Managing Director, BioTech Breakthrough. "By addressing one of surgery's most persistent challenges, D-PLEX₁₀₀ delivers better patient outcomes while reducing provider burdens and generating healthcare savings. Congratulations on winning 'Therapeutics Solution of the Year!'"

"We are deeply honored by this recognition, which recognizes the importance of our mission to address one of healthcare's most persistent challenges," said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. "With SSIs accounting for 20% to 31% of all hospital-acquired infections1, D-PLEX₁₀₀ represents a significant breakthrough. Our Phase 3 SHIELD II trial demonstrated a remarkable relative risk reduction of 58% (p< 0.005) in SSIs following abdominal colorectal surgery, addressing a critical gap where current approaches often fall short. At a time when hospitals face complex challenges in both preventing and reporting infections, D-PLEX₁₀₀ has the potential to transform surgical care by directly improving patient outcomes and hospital efficiency through meaningful infection reduction."

D-PLEX₁₀₀ has received Breakthrough Therapy Designation, three QIDP designations, and three Fast Track designations from the U.S. Food and Drug Administration. NDA submission is expected early 2026.

About D-PLEX₁₀₀D-PLEX₁₀₀, PolyPid’s lead product candidate, is designed to provide local prolonged and controlled anti-bacterial activity directly at the surgical site to prevent surgical site infections (“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 recently demonstrated positive results in the Phase 3 SHIELD II trial, achieving a statistically significant 58% (p< 0.005) relative risk reduction in SSI incidence following abdominal colorectal surgery with large incisions. D-PLEX₁₀₀ received Breakthrough Therapy designation from the U.S. Food and Drug Administration for the prevention of SSIs in patients undergoing elective colorectal surgery.
