FDA Agreed to PolyPid Request for the Addition of an Unblinded Interim Analysis in SHIELD I once 750 Patients Complete their 30–day Follow-up

Recruitment Progressing as Planned with Approximately 680 Patients Enrolled into Phase 3 SHIELD I Trial of D-PLEX₁₀₀ in Abdominal Soft Tissue Surgery. Expect to Reach 750 Enrolled Patients by End of First Quarter 2022 and Have Unblinded Interim Analysis During the Second Quarter of 2022

Recently Completed Planned 500–Patient Blinded Sample Size Reassessment of SHIELD I Supports the Continuation of the Trial

Conference Call Scheduled for Today at 8:30 AM ET

PETACH TIKVA, Israel, Feb. 09, 2022 — PolyPid Ltd. (Nasdaq: PYPD) (“PolyPid” or the “Company”), a Phase 3 biopharmaceutical company focused on developing targeted, locally administered, and prolonged-release therapeutics using its proprietary PLEX technology, today provided a corporate update and reported financial results for the three months and full-year ended December 31, 2021.

Recent Corporate Highlights:

• The U.S. Food and Drug Administration (the “FDA”) agreed to PolyPid’s request for the addition of an unblinded interim analysis in SHIELD I (Surgical site Hospital acquired Infection prEvention with Local D-PLEX) study evaluating D-PLEX₁₀₀ for the prevention of abdominal soft tissue surgical site infections (SSIs). PolyPid’s request was based on the FDA’s recently published guidance for pharmaceutical companies to address the impact of COVID-19 pandemic on meeting study objectives for clinical trials conducted during this period.
• The interim analysis is expected during the second quarter of 2022 once 750 patients complete their 30-day follow-up and will allow for early trial stopping due to efficacy, futility, or for sample size reassessment.
• Recruitment progressing as planned with approximately 680 patients enrolled into the ongoing Phase 3 SHIELD I study.
• Following the completion of the 30-day follow-up period for the 500th patient enrolled, the recently completed planned blinded sample size reassessment supports the continuation of SHIELD I trial.
• Patient enrollment is also advancing as anticipated in SHIELD II, the second Phase 3 clinical trial for D-PLEX₁₀₀ in abdominal surgery, with over 200 patients enrolled to date. SHIELD II has broader eligibility criteria than SHIELD I, including minimally invasive surgical procedures.
• Successful pre-Investigational New Drug (IND) meeting with the FDA supporting a Phase 1/2 clinical trial of OncoPLEX as a potential part of first-line combination therapy for patients newly diagnosed with Glioblastoma Multiform (GBM).
• Board of Directors appointed Dikla Czaczkes Akselbrad, currently Executive Vice President and Chief Financial Officer of the Company, as PolyPid’s Chief Executive Officer, effective July 1, 2022, at which time Amir Weisberg will retire from his position as Chief Executive Officer.

“Our team is achieving rapid progress in advancing our multiple development programs, as well as executing on the activities related to our commercial preparations for D-PLEX₁₀₀ for prevention of abdominal soft tissue SSIs,” stated Amir Weisberg, PolyPid’s Chief Executive Officer. “We are very pleased with the interim analysis in SHIELD I that will strengthen the adaptive design of the study so we can more precisely define the targeted patient enrollment range. It can also potentially allow for stopping the trial earlier than planned, if the efficacy results on SSIs are above expectations. We are also very satisfied with the study enrollment which continues at a strong pace, as we now have approximately 680 patients enrolled into the study, as compared to about 480 patients announced on our November 2021 conference call.”

“We believe PolyPid is in the strongest operational position in its history, and we are well-positioned for long-term success. We continue to anticipate that our current balance sheet will be sufficient to complete the SHIELD I study and prepare for the submission of an NDA to the FDA, as well as further advancement of our OncoPLEX development platform,” concluded Mr. Weisberg.

• Research and development (R&D) expenses for the three months ended December 31, 2021 were $9.5 million, compared to $5.0 million in the same three month period of 2020, as spending increased due to the expedited recruitment in SHIELD I and initiation of SHIELD II Phase 3 clinical trials in abdominal surgery.

• R&D expenses for the year ended December 31, 2021 were $30.4 million, compared to $17.0 million in 2020, as spending increased due to the initiation of SHIELD I and SHIELD II Phase 3 clinical trials in abdominal surgery.
• G&A expenses for the year ended December 31, 2021 were $9.5 million, compared to $7.7 million for 2020, as costs increased due to the Company’s status as a publicly-traded company with higher directors and officers insurance costs.
