PDUFA target action date of November 28, 2026, approximately one quarter ahead of Company’s previously communicated guidance

FDA identified no Filing review issues

Acceptance triggers $15 million milestone payment, completing $30 million in upfront and near-term milestone payments under recently announced U.S. and Canada commercialization partnership

PETACH TIKVA, Israel, July 29, 2026 (GLOBE NEWSWIRE) -- PolyPid Ltd. (NASDAQ:PYPD) ("PolyPid" or the "Company"), an innovative biopharmaceutical company dedicated to elevating treatment effectiveness, right where care begins, today announced that the U.S. Food and Drug Administration ("FDA") has accepted for filing the New Drug Application ("NDA") and granted the NDA a Priority Review for D-PLEX₁₀₀ for the prevention of surgical site infections ("SSIs") in patients undergoing abdominal colorectal surgery. The FDA did not identify any filing review issues and set a Prescription Drug User Fee Act ("PDUFA") target action date of November 28, 2026, approximately one quarter ahead of the Company’s previously communicated first quarter 2027 guidance. Priority Review shortens the FDA’s target review timeline from ten months to approximately six months.

"The FDA’s acceptance of our NDA with Priority Review, arriving with no filing review issues and an accelerated action date, is a defining regulatory milestone for PolyPid in our development of D-PLEX₁₀₀ as a potential new option to patients for the prevention of surgical site infections, pending the outcome of FDA’s review," said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. "We believe this outcome reflects the quality of our regulatory submission and the rigor of our development program for D-PLEX₁₀₀. Together with our commercial partner Azurity, we are fully aligned on supporting the Agency’s review, and on bringing D-PLEX_100, if approved, as a new option to patients for the prevention of SSIs following abdominal colorectal surgery."

The FDA’s acceptance of the NDA triggers a $15 million milestone payment from Azurity Pharmaceuticals ("Azurity"), completing the $30 million in upfront and near-term milestone payments previously announced under the exclusive commercial partnership signed on July 17, 2026.

The Company will continue to support the FDA’s review of the NDA through the November 28, 2026 PDUFA action date, ahead of a potential U.S. commercial launch of D-PLEX₁₀₀ by Azurity in early 2027.

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 with the goal of preventing abdominal surgical site infections ("SSIs"). Following the administration of D-PLEX₁₀₀ into the surgical site, PolyPid’s delivery technology, Kynatrix, is designed to pair 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. In the Phase 3 SHIELD II trial, D-PLEX₁₀₀ recently demonstrated positive results in achieving its primary end point and a 60% (p= 0.0013) relative risk reduction at the secondary end point 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.
