Thank you, Brian. On behalf of our team at PolyPid, I would like to welcome everyone to our first quarter 2024 earnings conference call. We are excited about the substantial momentum throughout our business. Most importantly, as it relates to enrollment in our ongoing SHIELD II pivotal trial for D-PLEX100 for the prevention of abdominal colorectal surgical site infection. Importantly, this clinical progress is being achieved with a recently fortified balance sheet.
Let's begin with the status of SHIELD II. I'm pleased to report today that the study has now enrolled more than 200 subjects and approximately 50 centers are currently open in multiple countries around the world, including the U.S., Germany, Italy, Ireland, Portugal, Hungary and Israel.
As a reminder, we intend to conduct an unblinded interim analysis once approximately 400 patients of the planned total of 600 subjects complete the 30-day follow-up, which is expected to occur in mid-2024. Top line results are anticipated in the second half of this year. Therefore, SHIELD II is now more than half enrolled for the interim analysis and more than 1/3 fully enrolled. Importantly, at the current status would indicate, enrollment is now progressing at a constantly robust space with respect to the expected recruitment rate. As we said on our last call, once the site is fully up and running, which takes several weeks following its being formally opened, we anticipate approximately 1.5 patients being recruited into this trial per center per month, and we expect to have a total of approximately 60 centers opened and recruiting patients.
So at the peak of the enrollment period, we anticipate recruiting 90 patients per month. Similar to the enrollment rate, we had in SHIELD I. With that said, having crossed the important 200 subject threshold, we thought we'd provide some color on several encouraging involvement trends we are seeing. Of note, the median age, male/female split and percentage of enrolled cancer patients in SHIELD II are similar to the patient population in the SHIELD I large incision pre-specified subgroup.
This is significant because we are thus far observing similar demographics in this more focused patient population, in which we have already generated highly positive data in SHIELD I. This is yet another reason we continue to strongly believe that SHIELD II is a derisked Phase III trial. Along with the fact that SHIELD II is not being conducted within the tight COVID-related restrictions that were in place during the pandemic and throughout the duration of SHIELD I.
Of course, we are also leveraging key learnings from SHIELD I related to the sites involved in the study. To this end, while we are targeting approximately 60 centers for SHIELD II around the same number as SHIELD I, we have firm knowledge of the best-performing sites from SHIELD I in terms of recruitment, patient monitoring and good clinical practice. We believe this to be essential in the execution of SHIELD II.
We have also enhanced our clinical operations team, another key step towards supporting the successful study. Moreover, the data safety monitoring committee in charge of the review of accumulated safety data and study conduct for SHIELD II study has twice recommended to continue the study without modification, meaning that no safety issues related to D-PLEX100 has been observed in SHIELD II to date. Moving on, to reiterate what we have said previously, we have a clear regulatory pathway for the potential NDA submission for D-PLEX100 in the U.S.
Last year, the FDA acknowledged not only the SHIELD I results may provide supportive evidence of the safety and efficacy of D-PLEX100 in patients with large surgical incision, but also confirmed that if successful, SHIELD II is sufficient to support a potential NDA submission. I'd like to take a moment to acknowledge an often overlooked key aspects of the compelling D-PLEX100 product profile. And that is its substantial intellectual property foundation.
Specifically, we are fast approaching 175 granted and pending applications patented for the PLEX platform and its uses for the treatment of different indication. Among those method of use patents our significant number of patents with long-term protection for D-PLEX100 for the prevention of surgical site infection. For example, our D-PLEX100 SSI patent is expected to remain in effect until 2035 in more than 40 countries worldwide.
This incredibly strong IP position only enhances the value of this promising late-stage product candidate for us. Shifting gears. We continue to advance SHIELD II from a strengthened financial position following our January 2024 private placement financing or PIPE for $16 million of gross proceeds. Importantly, our cash runway now extends into the fourth quarter of this year and beyond the anticipated timing of SHIELD II's planned unblinded interim analysis.
Moreover, the company has the potential to secure an additional $19 million if the result of the unlined interim analysis are positive and all of the warrants issued in the financing are exercised, which would fund PolyPid to the start of a planned rolling NDA submission for D-PLEX100. As a reminder, the PIPE syndicate was comprised of new and existing investors, including participation from U.S. life science-focused investors, DAFNA Capital Management and Rosalind Advisors.
Before I turn the call over to Jonny for his review of the financials, I'd like to let you all know that we have recently posted a newly revamped corporate presentation on our IR website. We would encourage all of you to take a look at your convenience.
With that, it is my pleasure to now turn the call over to Johnny. Johnny?
