**Exhibit 99.1**

**PolyPid Announces Positive Topline Results from Phase 3 SHIELD II Trial: D-PLEX<sub>100 </sub>Demonstrated Significant Reduction in Surgical Site Infections and Successfully Met Primary and All Key Secondary Endpoints**

 

● *D-PLEX<sub>100</sub> successfully met the primary efficacy endpoint, with statistically significant results (p<0.005) in 798 patients with large abdominal surgery incisions.* 

● *The trial successfully met all key secondary efficacy endpoints, including a 58% reduction in the rate of surgical site infections ("SSI") in patients treated with D-PLEX<sub>100</sub> arm versus standard of care ("SoC") arm (p<0.005).* 

 

● *The Company expects to submit a New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") in early 2026, with a Marketing Authorization Application ("MAA") in the E.U. to follow shortly thereafter.* 

● *PolyPid will conduct a conference call and webcast at 8:30 A.M. ET today.*

PETACH TIKVA, Israel, June 9, 2025 -- PolyPid Ltd. (Nasdaq: PYPD) ("**PolyPid**" or the "**Company**"), a late-stage biopharma company aiming to improve surgical outcomes, today announced positive topline results from its pivotal SHIELD II Phase 3 trial of D-PLEX<sub>100</sub> for the prevention of SSIs in patients undergoing abdominal colorectal surgery with large incisions, which has received Fast Track designation from the FDA.

"The positive results of our Phase 3 pivotal trial provide clear and compelling evidence of D-PLEX<sub>100</sub>'s ability to significantly reduce SSIs, a major burden on patients and healthcare systems, while improving clinical outcomes for both patients and physicians," said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. "D-PLEX<sub>100</sub> has the potential to meaningfully lower costs for hospitals and payers, and we believe it will be a valuable addition to the standard of care. Targeting a total addressable U.S. market of over 12 million annual surgeries and a significant unmet need, D-PLEX<sub>100 </sub> has the potential to make a substantial market impact. We remain on track for an NDA submission in early 2026 and believe these robust data will serve as a strong catalyst for advancing our global partnership discussions. We are deeply grateful to the patients, principal investigators, and study teams who made this milestone possible."

**<u>Key findings from SHIELD II study include:</u>**

● The primary efficacy endpoint of the study was successfully met, with a significantly lower proportion of primary endpoint events among patients who received D-PLEX<sub>100</sub> plus SoC (n=405; 10.9%), compared to SoC alone (n=393; 18.1%), representing a 38% reduction (p<0.005). The primary endpoint is the combination of deep and superficial SSIs, all-cause mortality and surgical reinterventions at the same incision of the original index surgery.

● SHIELD II included three key secondary endpoints:

○ The first key secondary endpoint was met, with a 58% reduction in deep and superficial SSI rates among patients who received D-PLEX<sub>100</sub> plus SoC (3.8%) compared to those who received SoC alone (9.5%) (p<0.005).

○ The second key secondary endpoint showed statistical significance in favor of D-PLEX<sub>100</sub> plus SoC over SoC alone (p<0.005). This efficacy endpoint combined SSI, mortality and reintervention as evaluated in the primary endpoint. This endpoint was assessed in the overall study population of 975 patients with an incision ≥7 cm, including laparoscopic surgery patients enrolled prior to the 2023 trial protocol change.

○ The third key secondary endpoint was met with a 62% reduction of patients with an ASEPSIS <sup>1</sup> score >20 in D-PLEX<sub>100</sub> plus SoC arm compared to SoC alone arm (p<0.05). The ASEPSIS score is a clinical tool used to objectively assess surgical wound infections.

● There were no safety concerns raised by the independent Data Safety Monitoring Board in SHIELD II.

"The risk of surgical site infection in the colorectal patient population has recently been documented to approach 23%<sup>2</sup> in patients with multiple comorbid risk factors," said Charles E. Edmiston, Jr., MS, PhD, CIC, FIDSA, FSIS, FAPIC Emeritus Professor of Surgery. "These topline results provide clinical practitioners with a novel, innovative strategy for reducing postoperative infection risk in patients undergoing colorectal surgery with large wound incisions. Based on the trial findings, particularly the significant risk-reduction benefit by reducing in-wound sepsis risk, I anticipate D-PLEX<sub>100</sub> technology will be rapidly embraced as a critical component to the current evidence-based surgical care bundle for colorectal surgery following FDA approval."

<sup>1</sup> ASEPSIS is an acronym of wound assessment and treatment parameters, which provides a numerical score during an inspection of the surgical site. The final score is interpreted by the severity of wound appearance and the clinical consequences of the infection. Parameters include: serous exudate, erythema, purulent exudate, separation of deep tissue and also antibiotic therapy, drainage of pus under local/general anesthesia, isolation of pathogenic bacteria and hospital stay as inpatient.

**About SHIELD II**

SHIELD II (Surgical site Hospital acquired Infection prEvention with Local D-PLEX) is a prospective, multinational, randomized, double blind Phase 3 trial designed to assess the efficacy and safety of D-PLEX<sub>100</sub> administered concomitantly with standard of care ("SoC"), which includes prophylactic systemic antibiotics, compared to SoC alone arm, in the prevention of post abdominal-surgery incisional infection in patients undergoing abdominal colorectal surgeries with large incisions. The primary endpoint of the trial is measured by the proportion of subjects with either a surgical site infection ("SSI") event as determined by a blinded and independent adjudication committee, reintervention, or mortality for any reason within 30 days post-surgery. Patient safety will be monitored for an additional 30 days. The trial will enroll patients in centers in the United States, Europe and Israel.

**About D-PLEX**<sub>100</sub>

D-PLEX<sub>100, </sub>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-PLEX<sub>100</sub> 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-PLEX<sub>100 </sub>received Breakthrough Therapy designation from the U.S. Food and Drug Administration for the prevention of SSIs in patients undergoing elective colorectal surgery. D-PLEX<sub>100 </sub>is currently in Phase 3 SHIELD II trial for the prevention of surgical site infections in patients undergoing abdominal colorectal surgery with large incisions.

**About PolyPid**

PolyPid Ltd. (Nasdaq: PYPD) is a late-stage biopharma company aiming to improve surgical outcomes. Through locally administered, controlled, prolonged-release therapeutics, PolyPid's proprietary PLEX (Polymer-Lipid Encapsulation matriX) technology pairs with Active Pharmaceutical Ingredients (APIs), enabling precise delivery of drugs at optimal release rates over durations ranging from several days to months. PolyPid's lead product candidate D-PLEX<sub>100</sub> is in a Phase 3 clinical trial for the prevention of abdominal colorectal surgical site infections. In addition, the Company is currently in preclinical stages to test the efficacy of OncoPLEX for the treatment of solid tumors, beginning with glioblastoma.
