Adding to Watch List on Heels of 90 Day Results, From First Small ‘In-Man’ Trial to Treat Chronic Venous Insufficiency affecting the legs, with Hancock’s VenoValve.
What Causes Chronic Venous Insufficiency?
Veins return blood to the heart from all the body’s organs. To reach the heart, the blood needs to flow upward from the veins in the legs. Calf muscles and the muscles in the feet need to contract with each step to squeeze the veins and push the blood upward. To keep the blood flowing up, and not back down, the veins contain one-way valves.
Chronic venous insufficiency occurs when these valves become damaged, allowing the blood to leak backward. Valve damage may occur as the result of aging, extended sitting or standing or a combination of aging and reduced mobility. Read More at Cleveland Clinic.
Principle Investigator Dr. Jorge Hernando Ulloa Reports New 90 Day VenoValve Data at the Second Annual Society of Vascular and Endovascular Surgery Congress of Central America and the Caribbean
Reflux Now at Normal Levels in All Four VenoValve Patients
IRVINE, CA / ACCESSWIRE / July 26, 2019 / Hancock Jaffe Laboratories, Inc. (Nasdaq: HJLI, HJLIW), a developer of medical devices that restore cardiac and vascular health, announced today that on Thursday, July 25, 2019, Dr. Jorge Hernando Ulloa, the Principle Investigator for HJLI’s first-in-man VenoValve study in Bogota, Colombia, reported new 90 day VenoValve data at the Second Annual Society of Vascular and Endovascular Surgery Congress of Central America and the Caribbean.
Dr. Ulloa reported that for all four patients with working VenoValves, reflux has been reduced to normal levels seen in patients without Chronic Venous Insufficiency (“CVI”). Reflux is the primary endpoint for HJLI’s ongoing VenoValve trial and is the main cause of severe CVI of the deep vein system. All patients had severe CVI prior to receiving their the VenoValve device, and the data was reported on patients 90 days post-VenoValve surgery implant.
Dr. Ulloa also reported that overall, reflux has been reduced an average of sixty-eight (68%) across all patients with the working VenoValves device, significantly more than the forty-five percent (45%) reduction that was reported this past June, at which time patients were 60 days post-surgery. VCSS scores, a measurement of venous disease severity graded by the clinician, has also continued to improve, with the average improvement across all four patients now at forty-nine percent (49%), compared to pre-operative levels. Pain across the patients, which is measured by a VAS score, has also decreased thirty-nine percent (39%).
Robert Berman, Hancock Jaffe’s Chief Executive Officer stated, “Our ninety (90) day data shows substantial improvement in our patients in all important areas. In addition, we have not experienced any significant device-related adverse events. At this point, the results that we are seeing with the VenoValves is exceptional.”
CVI is a condition that occurs when the valves in the veins of the leg are injured or destroyed, causing blood to flow backwards. The backwards flow of blood is known as reflux. The VCSS or Venous Clinical Severity Score consists of ten parameters that are used by clinicians to assess venous disease. The VAS score is a measure for pain that is commonly used in clinical trials. Reflux, VCSS scores, and VAS scores are all endpoints in Hancock Jaffe’s first-in-man Bogota study.
HJLI expects to release 180-day results for these five patients, and incremental results for other patients enrolled in the study, in October of 2019. A sixth patient that underwent a VenoValve implantation in June of 2019 is making excellent progress. The VenoValve is not currently functioning on one patient. That patient continues to do well and has shown modest improvement compared to pre-VenoValve surgery. To date, there have been no serious device-related adverse events associated with the VenoValves.
The initial phase of the first-in-man Colombian study will include up to ten patients who suffer from severe CVI. HJLI has implanted VenoValves in six patients and will continue to provide updates on patient enrollment and additional VenoValve implantations.
The purpose of the first-in-man study is to provide HJLI with valuable feedback to make any necessary product modifications or adjustments to the surgical implantation procedure for the VenoValve. HJLI expects to use the data from its first-in-man Bogota study as part of its Investigational Device Exemption (“IDE”) application to be submitted to the U.S. Food and Drug Administration (“FDA”) in order to begin the VenoValve U.S. pivotal trial. HJLI expects to file the IDE application in early 2020.
Approximately 2.4 million people in the U.S. suffer from CVI due to reflux in the deep venous system, representing a potential addressable U.S. market of approximately $14 Billion. Estimates indicate that direct medical costs from CVI in the U.S. exceed $30 Billion a year. There are currently no FDA approved devices, or effective treatments for deep venous CVI.
The meeting of the Society of Vascular and Endovascular Surgery of Central America and the Caribbean was hosted by the Society of Vascular and Endovascular Surgery of the Dominican Republic, in Santo Domingo. The conference focuses on the most recent technological advances in vascular and endovascular surgery and is aimed at specialists in vascular and cardiovascular medicine, as well as dermatologists, radiologists, vascular sonographers, nephrologists, cardiologists and family doctors.
