PolyPid ‘SHIELDS’ First Patient: Revamped Phase 3 Trial Evaluates New Treatment for Colorectal Surgical Site Infections

PolyPid Ltd. (Nasdaq: PYPD), a late-stage biopharma company, has announced that the first patient has been recruited for its revised SHIELD II Phase 3 trial, an exciting advancement in improving surgical outcomes. This trial will evaluate the use of D-PLEX100 for the prevention of abdominal colorectal surgical site infections (SSIs).

The FDA recently accepted the revised protocol for the trial, which will recruit an estimated 550 patients and have top-line results expected by mid-2024. Additionally, an interim analysis of 400 patients is planned once they complete their 30-day follow-up. With this breakthrough, PolyPid aims to revolutionize the healthcare sector and provide better outcomes for patients.

PolyPid is delighted to announce that the revised version of their late-stage D-PLEX100 development program trial, SHIELD II, has successfully recruited its first patient. SHIELD I had previously demonstrated a highly statistically significant reduction of 54% in surgical site infections in patients undergoing surgeries with large incisions.

As an effort to provide more security to this trial, SHIELD II will primarily be conducted in the most successful sites of SHIELD I, in terms of recruitment, patient monitoring and guaranteed clinical practice. PolyPid is excited to resume the trial and has bolstered their internal clinical operations capacity to ensure that SHIELD II progresses in a successful manner. Further updates on the trial’s progress will be made available in the near future.


Shield II is a groundbreaking Phase 3 clinical trial that aims to evaluate the efficacy and safety of D-PLEX100 as an additional preventive measure for post-abdominal surgery infection in patients undergoing incisions longer than 20 cm. Using a randomized, double-blind and multinational study model, Shield II will be measuring its primary endpoint – the proportion of subjects with surgical site infection, reintervention, or mortality within 30 days after their surgery – and track safety for an additional 30 days. Patients enrolled in the trial will come from medical centers in the United States, Europe, and Israel. Shield II is an exciting clinical study that could revolutionize how post-surgical infections are prevented.
