PolyPid Ltd. announced it has received written responses from the U.S. Food and Drug Administration (FDA) to a Type B meeting request that the Company submitted regarding its development plan for D-PLEX100. The FDA indicated that PolyPid’s proposal for a single Phase 3 pivotal study (SHIELD I), provided the study results are adequate, would provide sufficient evidence of clinical efficacy and safety to support approval of D-PLEX100 for the prevention of surgical site infections (SSIs) in colorectal surgery. The Type B meeting was requested following PolyPid’s receipt of Breakthrough Therapy Designation from the FDA for D-PLEX100 for the prevention of SSIs in patients undergoing elective colorectal surgery. Launched in July 2020, SHIELD I is a prospective, multinational, multicenter, randomized, double blind Phase 3 trial designed to assess the efficacy and safety of D-PLEX100 for the prevention of incisional SSIs post-abdominal surgery. The primary endpoint of the trial is the combination of incisional SSIs and mortality rate as measured by the proportion of subjects with either an SSI event, as determined by a blinded and independent adjudication committee, or mortality for any reason within 30 days post-surgery. The trial will enroll a minimum of 616 patients, with a maximum of about 900 patients, as defined by the adaptive study design, in more than 60 centers in the United States, Europe and Israel.
