Hancock Jaffe Receives Permission to Proceed with First-in-Human CoreoGraft Study

Patient Selection to Begin Immediately for CoreoGraft Study

IRVINE, CA / ACCESSWIRE / July 23, 2020 / Hancock Jaffe Laboratories, Inc. (NASDAQ:HJLI), a developer of medical devices that restore cardiac and vascular health, today announced that Italian Hospital Asuncion in Paraguay has given the Company permission to proceed with the CoreoGraft first-in-human study. The study had been delayed due to constraints at the hospital caused by the COVID-19 pandemic. Patient selection for the three to five-person study will begin immediately.

Based upon current COVID-19 constraints, Italian Hospital Asuncion has given permission to proceed with two CoreoGraft surgeries per week, once patients are enrolled in the study. Following patient enrollment, the CoreoGraft surgeries will likely be completed over a four-week period. CoreoGrafts will be implanted in patients needing coronary artery bypass graft ("CABG") surgeries.

CoreoGraft patients will be monitored for a one-year period post CoreoGraft surgery, with interim results reported at 30, 90, 180, and 365 days post-surgery. The Company will provide periodic updates on patient enrollment and dates for the surgeries once they are scheduled.

In January of 2020, HJLI released positive results from its six month CoreoGraft animal feasibility study. At 30, 90, and 180 days post CoreoGraft bypass surgeries, all grafts we patent (open), when the implantations went smoothly and there were no technical errors. At the conclusion of the study, pathology examinations of the grafts and surrounding tissue showed no signs of thrombosis, infection, aneurysmal degeneration, changes in the lumen, or other problems that are known to plague saphenous vein grafts ("SVGs"). In addition, the pathology examinations indicated a thin layer of endothelial cells in the CoreoGrafts that were implanted for 90 days, and more complete endothelization was observed for grafts implanted for 180 days both throughout the CoreoGrafts and into the left anterior descending arteries. Endothelialization is thought to be a critical step in establishing the long-term biocompatibility of cardiovascular devices.

For patients with suitable veins, the current standard of care for most CABG surgeries is to harvest the saphenous vein from the leg of the patient, dissect the SVGs into multiple grafts, and to use the dissected grafts to revascularize the heart. In addition to the vein harvest procedure being invasive, painful, and subject to its own complications for the patient, SVGs are also known to have high short term and long-term failure rates when used as grafts around the heart. Studies indicate that up to 40% of SVGs fail within one year of CABG surgeries, with a significant percentage failing within the first 30 days. Eight to ten years after surgery, SVG failure rates are known to be in as high as 75%. Eventually, the CoreoGraft could become a viable alternative to using SVGs.

Approximately 200,000 CABG surgeries are performed each year in the U.S., representing more than 55% of all cardiac surgeries and accounting for between $15 Billion and $25 Billion in annual expenditures. With an average of three grafts used per surgery, HJLI estimates the potential U.S. addressable market for the CoreoGraft to be more than $2 Billion per year. There are currently no FDA approved prosthetic grafts for CABG surgeries.

About Hancock Jaffe Laboratories, Inc.

HJLI specializes in developing and manufacturing bioprosthetic (tissue based) medical devices to establish improved standards of care for treating cardiac and vascular diseases. HJLI currently has two lead product candidates: the VenoValveÒ, a porcine based valve which is intended to be surgically implanted in the deep venous system of the leg to treat reflux associated with Chronic Venous Insufficiency; and the CoreoGraftÒ, a bovine tissue based off the shelf conduit intended to be used for coronary artery bypass surgery.
