Recruitment Progressing as Planned with Nearly 200 Patients Enrolled into Phase 3 SHIELD I Trial of D-PLEX₁₀₀ in Abdominal Surgery

Recruitment Rate in SHIELD I trial Doubled in the Last Three Weeks

Manufacturing Facility Now Fully Scaled Up and Capable of Supporting at Least First 30 Months of Anticipated Commercial Demand for D-PLEX₁₀₀

Conference Call Scheduled for Today at 8:30 AM ET

PETAH TIKVA, Israel, May 12, 2021 — PolyPid Ltd. (Nasdaq: PYPD), a late-stage biopharma company aiming to improve surgical outcomes through locally administered, controlled, extended-release therapeutics, today provided a corporate update and reported financial results for the three months ended March 31, 2021.

Recent Corporate Highlights:

• Recruitment progressing as planned with nearly 200 patients enrolled into the ongoing Phase 3 SHIELD I (Surgical site Hospital-acquired Infection PrEvention with Local D-plex) study, the first of two ongoing Phase 3 clinical trials of the Company’s lead product candidate D-PLEX₁₀₀, for the prevention of surgical site infections (SSIs) in abdominal surgery (soft tissue).
• The Company plans to enroll 616-900 patients undergoing high priority operations in 60 centers in the United States, Europe and Israel. Following the enrollment of approximately 500 patients, the study design provides for a blinded sample size re-estimation.
• Enrollment is also advancing as anticipated in SHIELD II, the second of two Phase 3 clinical trials for D-PLEX₁₀₀ in abdominal surgery (soft tissue). SHIELD II will enroll approximately 900-1,400 patients across 60 centers in the United States, Europe and Israel and has broader eligibility criteria, including minimally invasive surgical procedures.
• Manufacturing facility is now fully scaled up and capable of producing the first 30 months of anticipated commercial demand for D-PLEX₁₀₀.
• Continued to generate compelling preclinical data from the Company’s new OncoPLEX intra-tumoral cancer therapy program. OncoPLEX utilizes PolyPid’s PLEX technology in the intra-operative tumor resection setting to provide prolonged and controlled exposure to docetaxel within the tumor resected site, which is important to prevent local tumor recurrence and the potential spreading of cancer cells.

“We have made significant progress advancing our promising development programs and continuing our evolution towards successful commercialization,” said Amir Weisberg, PolyPid’s Chief Executive Officer. “Our robust Phase 3 trials for D-PLEX₁₀₀ for the prevention of SSIs, SHIELD I and SHIELD II, continue to enroll patients at the expected rate. To this end, we are thrilled to report that the recruitment rate in SHIELD I trial doubled in the last three weeks and that we have now enrolled nearly 200 patients in the trial. We continue to anticipate the availability of top-line results for SHIELD I by year-end 2021 and top-line results from SHIELD II by the end of next year.”

“We also continue to generate additional compelling preclinical data with OncoPLEX, including positive safety data in a promising solid tumor indication,” continued Mr. Weisberg. “We are excited to further progress our OncoPLEX development program and potentially initiate a first-in-man Phase 1 clinical trial in 2022.”

“Our strong balance sheet continues to drive our robust clinical development program. Our cash runway extends into 2022 and we remain well-positioned to complete the SHIELD I study and conduct SHIELD II, as well as prepare for the submission of a New Drug Application to the FDA with cash on hand,” concluded Mr. Weisberg.

Financial results for three months ended March 31, 2021

• Research and development expenses for the three months ended March 31, 2021 were $6.0 million, compared to $3.4 million in the same three-month period of 2020, as spending increased due to the ongoing SHIELD I and SHIELD II Phase 3 clinical trials in abdominal surgery.
• Marketing and business development expenses for the three months ended March 31, 2021 were $0.7 million, compared to $0.3 million for the same period of 2020, as spending increased primarily due to additional marketing and business development personnel hired in the Company’s New Jersey offices.
• General and administrative expenses for the three months ended March 31, 2021 were $2.1 million, compared to $0.7 million for the same period of 2020. This increase was due to the increase in costs due to the Company’s status as a publicly traded company with higher D&O insurance costs and an increase in non-cash share-based compensation.
• For the three months ended March 31, 2021, the Company had a net loss attributable to ordinary shares of $8.7 million, compared to a net loss of $5.9 million, in the three-month period ended March 31, 2020.
• As of March 31, 2021, the Company had cash and cash equivalents, short-term deposits and long-term deposits in the amount of $61.4 million, compared to $66.6 million at December 31, 2020. PolyPid continues to expect that this cash balance will be sufficient to fund operations into 2022.

About D-PLEX₁₀₀
PolyPid’s lead product candidate, D-PLEX₁₀₀, is a novel drug product candidate designed to provide local prolonged and controlled anti-bacterial activity directly at the surgical site to prevent SSIs. Following the administration of D-PLEX₁₀₀ into the surgical site, the PLEX technology enables a prolonged and constant release of the broad-spectrum antibiotic doxycycline, resulting in high local concentration of the drug for a period of four weeks for the prevention of SSIs, with additional potential to prevent SSIs caused by antibiotic-resistant bacteria at the surgical site. D-PLEX₁₀₀ has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for the prevention of SSIs in patients undergoing elective colorectal surgery. D-PLEX₁₀₀ has also received two Qualified Infectious Disease Product (QIDP) designations as well as two Fast Track designations for the prevention of post-abdominal surgery incisional infection and for the prevention of sternal wound infection post-cardiac surgery.
