Hancock Jaffe Enrolls Four Additional Patients for First-in-Human VenoValve Study

Implantations to Take Place by End of April with Initial Data Expected in June 2019

IRVINE, CA / ACCESSWIRE / March 21, 2019 / Hancock Jaffe Laboratories, Inc. (NASDAQ: HJLI), a developer of medical devices that restore cardiac and vascular health, has enrolled four additional patients for its VenoValve first-in-human study in Bogota, Colombia. HJLI expects to implant VenoValves in the four additional patients by the end of April 2019.

Robert Berman, Hancock Jaffe's Chief Executive Officer stated, ''We continue to make progress with our VenoValve first-in-human study and are excited to get these implantations underway so that we can continue to receive the feedback and accumulate the data that we need for our U.S. pivotal trial. Today's enrollment milestone represents the midpoint, as half of the first group of patients needed are now in our study.''

Following these implantations, five patients will have received VenoValves. The first-in-human Colombian study will initially include five to ten patients who suffer from severe, chronic venous insufficiency (CVI) of the deep vein system, a condition that occurs when the valves in the veins of the venous system of the leg are injured or destroyed, causing blood to flow backwards (reflux) and pool in the lower extremities, and resulting in increased venous pressure (venous hypertension). Severe CVI often results in significant disability which includes swelling, intense pain, and skin ulcerations that become ongoing, open wounds.

Following implantations of the VenoValve, as part of the study patients undergo duplex scans, which are used to measure reflux time - the duration of reflux in the deep venous system. The VenoValve was developed to reduce or eliminate deep venous reflux, a major cause of CVI. The reduction or elimination of reflux would lower venous hypertension and result in greatly improved quality of lives for patients suffering from deep venous CVI. In addition to measuring reflux, endpoints for the first-in-human VenoValve study include VCSS measurements, VAS scores, and VEINES scores, three well known clinical assessments for venous disease and assessments of improvement in the patient's quality of life and reduction in pain.

HJLI has had several Pre-FDA meetings to discuss the pre-clinical and clinical pathway for FDA approval for the VenoValve. Preclinical prototype testing, including in vivo animal studies, and in vitro hemodynamic studies, have demonstrated that the VenoValve mimics the function of a properly functioning native venous valve. Based upon feedback from the FDA, HJLI agreed to conduct a small first-in-human study in Colombia prior to the U.S. pivotal trial. The first-in-human study will provide HJLI with valuable feedback to make any necessary product modifications or adjustments to the surgical implantation procedures for the VenoValve.

HJLI expects to release preliminary data on the first group of VenoValve recipients at the end of June of 2019 and will continue to follow the patients in Colombia for a period of six months. Approximately 2.4 million patients in the U.S. suffer from CVI due to reflux in the deep venous system, and there are currently no FDA approved treatments for the condition.
