U.S. Commercialization Partnership Negotiations on Track

PETACH TIKVA, Israel, March 31, 2026 (GLOBE NEWSWIRE) -- PolyPid Ltd. (Nasdaq: PYPD) (“PolyPid” or the “Company”), an innovative biopharmaceutical company dedicated to improving patient outcomes by elevating treatment effectiveness, right where care begins, today announced that it has initiated a New Drug Application (“NDA”) submission to the U.S. Food and Drug Administration (the “FDA”) for D-PLEX₁₀₀ for the prevention of surgical site infections (“SSIs”) in patients undergoing colorectal surgery.

The NDA is being submitted under the FDA’s Fast Track designation, which allows for rolling review. The submission includes the Chemistry, Manufacturing and Controls (CMC) and nonclinical sections of the NDA, with additional components, including the clinical section, expected to be submitted in the second quarter of 2026.

“This submission marks a pivotal milestone for PolyPid as we advance D-PLEX₁₀₀ into its regulatory approval phase,” said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. “Following the positive results from our successful Phase 3 SHIELD II trial and constructive feedback from our previously announced pre-NDA meeting with the FDA, we are pleased to initiate the NDA submission. We are highly focused on executing toward potential approval and commercialization, with the goal of bringing D-PLEX₁₀₀ to patients undergoing surgery, while advancing discussions for a U.S. commercialization partnership.”

About D-PLEX₁₀₀
D-PLEX₁₀₀, 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, PolyPid’s delivery technology, Kynatrix, 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 60% (p= 0.0013) relative risk reduction in SSI incidence following abdominal colorectal surgery with large incisions. D-PLEX₁₀₀ received Breakthrough Therapy Designation from the FDA for the prevention of SSIs in patients undergoing elective colorectal surgery.

Risks

  • Approval of D-PLEX100 by the FDA is not guaranteed despite positive trial results and the Fast Track designation; regulatory risk remains significant.
  • Potential delays or changes in the completion timeline of NDA submission and FDA approval process could impact commercial launch timing.
  • Reliance on successful commercialization partnerships in the U.S. creates dependency risk on third-party collaborators for product rollout and market penetration.
