Note 3 – Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, such statements include all adjustments (consisting only of normal recurring items) which are considered necessary for a fair presentation of the unaudited condensed financial statements of the Company as of June 30, 2021 and December 31, 2020, and for the three and six months ended June 30, 2021 and 2020. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the operating results for the full year. These unaudited condensed financial statements should be read in conjunction with the financial statements and notes thereto for the year ended December 31, 2020 included in the Company’s Form 10-K filed with the SEC on March 31, 2021. The condensed balance sheet as of December 31, 2020 has been derived from the Company’s audited financial statements.

Concentrations

The Company maintains cash with major financial institutions. Cash held in United States bank institutions is currently insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 at each institution. There was an aggregate uninsured cash balance of $40,789,182 as of June 30, 2021.

Net Loss per Share

The Company computes basic and diluted loss per share by dividing net loss attributable to common stockholders by the weighted average number of common stock outstanding during the period. Basic and diluted net loss per common share are the same since the inclusion of common stock issuable pursuant to the exercise of warrants and options, would have been anti-dilutive.

Subsequent Events

The Company evaluated events that have occurred after the balance sheet date through the date the financial statements were issued. Based upon the evaluation and transactions, the Company did not identify any other subsequent events that would have required adjustment or disclosure in the financial statements.

Recent Accounting Standards

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. There was not a significant impact to the financial statements from the adoption of this standard.

As of June 30, 2021 and December 31, 2020, property and equipment consist of the following:

Depreciation expense amounted to $59,058 and $44,961 for the six months ended June 30, 2021 and 2020, respectively. Depreciation expense is reflected in general and administrative expenses in the accompanying statements of operations.

Note 5 – Right-of-Use Assets and Lease Liability

On September 20, 2017, the Company renewed its operating lease for its manufacturing facility in Irvine, California, effective October 1, 2017, for five years with an option to extend the lease for an additional five years at the end of the initial lease term. The initial lease rate was $26,838 per month with escalating payments. In connection with the lease, the Company is obligated to pay $7,254 monthly for operating expenses for building repairs and maintenance. The Company has no other operating or financing leases with terms greater than 12 months.

The Company accounts for this lease following the guidance in ASC Topic 842, Leases, and elected to adopt the short-term lease exception and not apply Topic 842 to arrangements with lease terms of 12 months or less. The Company determined the lease liabilities using the Company’s estimated incremental borrowing rate of 8.5% to estimate the present value of the monthly lease payments.

Overview

Hancock Jaffe Laboratories, Inc. is a medical device company developing tissue-based devices that are designed to be life sustaining or life enhancing for patients with cardiovascular disease, and peripheral arterial and venous disease. The Company’s products are being developed to address large unmet medical needs by either offering treatments where none currently exist or by substantially increasing the current standards of care. Our products which we are developing include: the VenoValve®, a porcine based device to be surgically implanted in the deep venous system of the leg to treat a debilitating condition called chronic venous insufficiency (“CVI”); and the CoreoGraft®, a bovine based conduit to be used to revascularize the heart during coronary artery bypass graft (“CABG”) surgeries. Both of these products are currently being developed for approval by the U.S. Food and Drug Administration (“FDA”). Our current senior management team has been affiliated with more than 50 products that have received FDA approval or CE marking. We currently lease a 14,507 sq. ft. manufacturing facility in Irvine, California, where we manufacture products for our clinical trials and which has previously been FDA certified for commercial manufacturing of devices.

Each of our products will be required to successfully complete significant clinical trials to demonstrate the safety and efficacy of the product before it will be able to be approved by the FDA.

We are in the process of developing the following bioprosthetic implantable devices for peripheral vascular and cardiovascular disease:

VenoValve

The VenoValve is a porcine based valve developed at HJLI to be implanted in the deep venous system of the leg to treat severe CVI. By reducing reflux, and lowering venous hypertension, the VenoValve has the potential to reduce or eliminate the symptoms of deep venous, severe CVI, including venous leg ulcers. The current version of the VenoValve is designed to be surgically implanted into the patient via a 5 to 6 inch incision in the upper thigh.

There are presently no FDA approved medical devices to address valvular incompetence, or effective treatments for deep venous CVI. Current treatment options include compression garments, or constant leg elevation. These treatments are generally ineffective, as they attempt to alleviate the symptoms of CVI without addressing the underlying causes of the disease. In addition, we believe that compliance with compression garments and leg elevation is extremely low, especially among the elderly. Valve transplants from other parts of the body have been attempted, but with very-poor results. Many attempts to create substitute valves have also failed, usually resulting in early thromboses. The premise behind the VenoValve is that by reducing the underlying causes of CVI, reflux and venous hypertension, the debilitating symptoms of CVI will decrease, resulting in improvement in the quality of the lives of CVI sufferers.

We estimate that there are approximately 2.4 million people in the U.S. that suffer from deep venous CVI due to valvular incompetence.

VenoValve Clinical Status

After consultation with the FDA, and as a precursor to the U.S. pivotal trial, we conducted a small first-in-human study for the VenoValve in Colombia. The first-in-human Colombian trial included 11 patients. In addition to providing safety and efficacy data, the purpose of the first-in-human study was to provide proof of concept, and to provide valuable feedback to make any necessary product modifications or adjustments to our surgical implantation procedures for the VenoValve prior to conducting the U.S. pivotal trial. In December of 2018, we received regulatory approval from Instituto Nacional de Vigilancia de Medicamentos y Alimentos (“INVIMA”), the Colombian equivalent of the FDA. On February 19, 2019, we announced that the first VenoValve was successfully implanted in a patient in Colombia. Between April of 2019 and December of 2019, we successfully implanted VenoValves in 10 additional patients, completing the implantations for the Colombian first-in-human study. Overall, VenoValves have been implanted in all 11 patients. Endpoints for the VenoValve first-in-human study include safety (device related adverse events), reflux, measured by doppler, a VCSS score used by the clinician to measure disease severity, and a VAS score used by the patient to measure pain, and a quality of life measurement.

Final results from the first-in-human study were released in December of 2020. Among the 11 patients, reflux improved an average of 54%, Venous Clinical Severity Scores (“VCSSs”) improved an average of 56%, and visual analog scale (VAS) scores, which are used by patients to measure pain, improved an average of 76%, when compared to pre-surgery levels. VCSS scores are commonly used by clinicians in practice and in clinical trials to objectively assess outcomes in the treatment of venous disease, and include ten characteristics including pain, inflammation, skin changes such as pigmentation and induration, the number of active ulcers, and ulcer duration. The improvement in VCSS scores is significant and indicates that almost all of the VenoValve patients who had severe CVI pre-surgery, had mild CVI or the complete absence of disease at one-year post surgery. Quality of life measured by a VEINES score showed statistically significant improvement.

VenoValve safety incidences were minor with no reported device related adverse events. Minor non-device related adverse safety issues included one (1) fluid pocket (which was aspirated), intolerance from Coumadin anticoagulation therapy, three (3) minor wound infections (treated with antibiotics), and one occlusion due to patient non-compliance with anti-coagulation therapy.

In preparation for the VenoValve U.S. pivotal trial, we submitted a Pre-IDE filing with the FDA in October of 2020 and had a pre IDE meeting with the FDA on January 11, 2021. Topics presented at the meeting included the background and clinical need for the VenoValve, proposed U.S. pivotal study design, patient monitoring protocols for safety and efficacy, bench testing protocols used to develop the device, and the VenoValve first-in-human results. We received valuable feedback from the FDA in several areas during the Pre-IDE meeting and believe we reached consensus on many important issues.

An investigational device exemption or IDE from the FDA is required before a medical device company can proceed with a pivotal trial for a class III medical device. On March 5, 2021 we filed an IDE application with the FDA for the VenoValve U.S. pivotal trial. On April 1, 2021, twenty-seven days after filing the IDE application, we received notification from the FDA that our IDE application was approved. The U.S. pivotal for the VenoValve will be known at the SAVVE (Surgical Anti-reflux Veno Valve Endoprosthesis) study and is a prospective, non-blinded, single arm, multi-center study of seventy-five (75) CVI patients enrolled at up to 20 U.S. sites.

Endpoints for the SAVVE trial mirror those endpoints used for the first-in-human trial, and include the absence of material adverse safety events (mortality, deep wound infection, major bleeding, ipsilateral deep vein thrombosis, pulmonary embolism) at thirty (30) days post implantation, reductions of reflux at one hundred and eighty days (180) days post VenoValve implantation, VCSS scoring to measure disease manifestations, VAS scores to measure pain, and quality of life measurements. We have significant interest from key opinion leaders and several of the top vascular clinicians in the U.S. who would like to participate in the VenoValve U.S. pivotal trial. We are in the process of qualifying the sites, seeking investigational review board (“IRB”) and other necessary approvals, negotiating clinical trial agreements, and preparing for site training and initiations. At this point we expect the first implantation for the SAVVE study to occur during the third quarter of 2021.

On August 3, 2020, we announced that the FDA granted Breakthrough Device Designation status to the VenoValve. The FDA’s Breakthrough Devices Program was established to enable priority review for devices that provide more effective treatment or diagnosis of life threatening or irreversibly debilitating diseases or conditions. The goal of the FDA’s Breakthrough Devices Program is to provide patients and health care providers with timely access to medical devices by speeding up their development, assessment, and review, while preserving the FDA’s mission to protect and promote public health.

CoreoGraft

The CoreoGraft is a bovine based off the shelf conduit that could potentially be used to revascularize the heart, instead of harvesting the saphenous vein from the patient’s leg. In addition to avoiding the invasive and painful SVG harvest process, HJLI’s CoreoGraft closely matches the size of the coronary arteries, eliminating graft failures that occur due to size mismatch. In addition, with no graft harvest needed, the CoreoGraft could also reduce or eliminate the inner thickening that burdens and leads to failure of the SVGs.

In addition to providing a potential alternative to SVGs, the CoreoGraft could be used when making grafts from the patients’ own arteries and veins is not an option. For example, patients with significant arterial and vascular disease often do not have suitable vessels to be used as grafts. For other patients, such as women who have undergone radiation treatment for breast cancer and have a higher incidence of heart disease, using the LIMA may not be an option if it was damaged by the radiation. Another example are patients undergoing a second CABG surgery. Due in large part to early SVG failures, patients may need a second CABG surgery. If the SVG was used for the first CABG surgery, the patient may have insufficient veins to harvest. While the CoreoGraft may start out as a product for patients with no other options, if the CoreoGraft establishes good short term and long term patency rates, it could become the graft of choice for all CABG patients in addition to the LIMA.

CoreoGraft Clinical Status

In January of 2020, we announced the results of a six-month, nine sheep, animal feasibility study for the CoreoGraft. Bypasses were accomplished by attaching the CoreoGrafts from the ascending aorta to the left anterior descending artery, and surgeries were preformed both on-pump and off-pump. Partners for the feasibility study included the Texas Heart Institute, and American Preclinical Services.

Test subjects were evaluated via angiograms and flow monitors during the study, and a full pathology examination of the CoreoGrafts and the surrounding tissue was performed post necropsy.

The results from the feasibility study demonstrated that the CoreoGrafts remained patent (open) and fully functional at 30, 90, and 180 day intervals after implantation. In addition, pathology examinations of the grafts and surrounding tissue at the conclusion of the study showed no signs of thrombosis, infection, aneurysmal degeneration, changes in the lumen, or other problems that are known to plague and lead to failure of SVGs.

In addition to exceptional patency, pathology examinations indicated full endothelialization for grafts implanted for 180 days both throughout the CoreoGrafts and into the left anterior descending arteries. Endothelium is a layer of cells that naturally exist throughout healthy veins and arteries and that act as a barrier between blood and the surrounding tissue, which helps promote the smooth passage of blood. Endothelium are known to produce a variety anti-clotting and other positive characteristics that are essential to healthy veins and arteries. The presence of full endothelialization within the longer term CoreoGrafts indicates that the graft is being accepted and assimilated in a manner similar to natural healthy veins and arteries that exist throughout the vascular system and is an indication of long-term biocompatibility.

In May of 2020, we announced that we had received approval from the Superintendent of Health of the National Health Counsel for the Republic of Paraguay to conduct a first-in-human, feasibility trial for the CoreoGraft. Up to 5 patients that need coronary artery bypass graft surgery were to receive CoreoGraft implants as part of the first-in-human study. In July of 2020, we announced that we had received permission to proceed with the first-in-human study, which had been put on hold due to the COVID-19 pandemic, and in August of 2020 we announced that the first two patients had been enrolled for the first-in-human CoreoGraft trial. Heart bypass surgeries for the first two patients to receive CoreoGraft implants as part of our first-in-human trial were successfully completed in October of 2020. A third bypass surgery using the CoreoGraft was successfully completed in November of 2020 and another surgery was completed in December of 2020. Two CoreoGraft surgical patients have expired due to non-device related adverse events, one in October and one in November of 2020. As a result of these deaths, the feasibility study was put on hold, pending a review by an ethics committee that oversees the feasibility trial. Although the committee has given approval to resume with the feasibility study, due to the recent resurgence of COVID-19 in South America (including in Paraguay), the first-in-human CoreoGraft feasibility trial remains on hold. At this time we have no further information as to when the study might resume.

Comparison of the three months ended June 30, 2021 and 2020

Overview

We reported net losses of $2.4 million and $1.6 million for the three months ended June 30, 2021 and 2020, respectively, representing an increase in net loss of $0.8 million or 50%, due to an increase in operating expenses of $0.9 million, and a decrease in other income and expense of $0.1 million.
