The Company has not established an ongoing source of revenue sufficient to cover its operating costs and to allow it to continue as a going concern. The accompanying financial statements for the period ended March 31, 2022 have been prepared assuming the Company will continue as a going concern. Although the Company&#8217;s cash resources will likely be sufficient to meet its anticipated needs during the next twelve months, the Company will require additional financing to fund its future planned operations, including research and development and commercialization of its products.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it establishes a revenue stream and becomes profitable. Management&#8217;s plans to continue as a going concern include raising additional capital through sales of equity securities and borrowing. However, management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. As described further below under &#8220;Item 2. Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations&#8221; the COVID-19 pandemic has impacted the Company&#8217;s business operations to some extent and is expected to continue to do so and, in light of the effect of such pandemic on financial markets, these impacts may include reduced access to capital. If the Company is not able to obtain the necessary additional financing on a timely basis, the Company will be required to delay, reduce the scope of, or eliminate one or more of the Company&#8217;s research and development activities or commercialization efforts or perhaps even cease the operation of its business. The ability of the Company to continue as a going concern is dependent upon its ability to successfully secure other sources of financing and attain profitable operations. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.</p></ix:nonNumeric><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><span style="text-decoration:underline">Recent Accounting Pronouncements</span></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><ix:nonNumeric id="fid_357" name="us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock" contextRef="From2022-01-01to2022-03-31" escape="true"><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company considered&#160;recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC, did not or in management&#8217;s opinion will not have a material impact on the Company&#8217;s present or future consolidated financial statements.</p></ix:nonNumeric></ix:continuation><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><ix:nonNumeric id="fid_335" name="us-gaap:InventoryDisclosureTextBlock" contextRef="From2022-01-01to2022-03-31" escape="true"><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Note 3 &#8211; Inventory</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">As of March 31, 2022 and December 31, 2021, inventory consisted of raw materials and subassemblies to be used in the assembly of a TAEUS system.

Forward-looking statements, which are based on certain assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of forward-looking terms such as &#8220;believe,&#8221; &#8220;expect,&#8221; &#8220;may,&#8221; &#8220;will,&#8221; &#8220;should,&#8221; &#8220;could,&#8221; &#8220;seek,&#8221; &#8220;intend,&#8221; &#8220;plan,&#8221; &#8220;estimate,&#8221; &#8220;anticipate&#8221; or other comparable terms. All statements other than statements of historical facts included in this Form 10-Q regarding our strategies, prospects, financial condition, operations, costs, plans and objectives are forward-looking statements. Examples of forward-looking statements include, among others, statements we make regarding expectations for revenues, cash flows and financial performance, the anticipated results of our development efforts and the timing for receipt of required regulatory approvals and product launches. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: our limited commercial experience, limited cash and history of losses; our ability to obtain adequate financing to fund our business operations in the future; our ability to achieve profitability; our ability to develop a commercially feasible application based on our Thermo-Acoustic Enhanced Ultrasound (&#8220;TAEUS&#8221;) technology; market acceptance of our technology; uncertainties associated with COVID-19 or coronavirus, including its possible effects on our operations; results of our human studies, which may be negative or inconclusive; our ability to find and maintain development partners; our reliance on collaborations and strategic alliances and licensing arrangements; the amount and nature of competition in our industry; our ability to protect our intellectual property; potential changes in the healthcare industry or third-party reimbursement practices; delays and changes in regulatory requirements, policy and guidelines including potential delays in submitting required regulatory applications for Food and Drug Administration (&#8220;FDA&#8221;) approval; our ability to obtain and maintain CE mark certification and secure required FDA and other governmental approvals for our TAEUS applications; our ability to comply with regulation by various federal, state, local and foreign governmental agencies and to maintain necessary regulatory clearances or approvals; and the other risks and uncertainties described in the Risk Factors section of our Annual Report on Form 10-K for the period ended December 31, 2021, as filed with the SEC on March 30, 2022, and in the Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations section of this Form 10-Q. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Available Information</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">From time to time, we use press releases, Twitter (@endralifesci) and LinkedIn (www.linkedin.com/company/endra-inc) to distribute material information.

Building on our expertise in thermoacoustics, we have developed a next-generation technology platform - Thermo Acoustic Enhanced Ultrasound, or TAEUS - which is intended to enhance the capability of clinical ultrasound technology and support the diagnosis and treatment of a number of significant medical conditions that currently require the use of expensive CT or MRI imaging or where imaging is not practical using existing technology.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The first-generation TAEUS application is a standalone ultrasound accessory designed to cost-effectively quantify fat in the liver and stage progression of nonalcoholic fatty liver disease (&#8220;NAFLD&#8221;), which can otherwise only be achieved today with impractical surgical biopsies or MRI scans. Subsequent TAEUS offerings are expected to be implemented via a second generation hardware platform that can run multiple clinical software applications that we will offer TAEUS users for a one-time licensing fee - adding ongoing customer value to the TAEUS platform and a growing software revenue stream for our Company.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"><tbody><tr style="height:15px"><td class="hpbhr">&#160;</td></tr><tr style="height:15px"><td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">15</td></tr><tr style="height:15px"><td><p style='page-break-after: always'></p></td></tr><tr style="height:15px"><td><em><a href="#toc">Table of Contents</a></em></td></tr></tbody></table><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Each of our TAEUS platform applications will require regulatory approvals before we are able to sell or license the application.

Currently, our marketing efforts are through our website and attendance of key industry meetings and conferences. In connection with the commercialization of our TAEUS applications, we are building a small sales and marketing team to train and support global ultrasound distributors, and expect to execute traditional marketing activities such as promotional materials, electronic media and participation in industry events and conferences. As of March 31, 2022, we had one full-time sales representative in the United Kingdom, two representatives in France and one in Germany. We expect to continue actively adding to our sales representation and support headcount for operations in the EU in the coming quarters, and plan to begin staffing our sales efforts in the United States once we have obtained FDA approval for the sale of the NAFLD TAEUS device in that region.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><em><span style="text-decoration:underline">General and Administrative Expenses</span></em></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">General and administrative expenses consist primarily of salaries and related expenses for our management and personnel, and professional fees, such as for accounting, consulting and legal services. We anticipate that our general and administrative expenses will increase in the future as we support our continued research and development activities, expand our sales and marketing operations, and continue as a public company. These increases would likely include increased costs related to the hiring of personnel, including compensation and employee-related expenses, including stock-based compensation, and fees to outside consultants, lawyers and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with The Nasdaq Capital Market and SEC requirements, directors and officers insurance, increased legal and accounting costs and investor relations costs.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"><tbody><tr style="height:15px"><td class="hpbhr">&#160;</td></tr><tr style="height:15px"><td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">16</td></tr><tr style="height:15px"><td><p style='page-break-after: always'></p></td></tr><tr style="height:15px"><td><em><a href="#toc">Table of Contents</a></em></td></tr></tbody></table><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Critical Accounting Policies and Estimates</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><em><span style="text-decoration:underline">Use of Estimates</span></em></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

On January 1, 2022, the pool of shares issuable under the Omnibus Plan automatically increased by 1,622,848 shares from 7,461,228 shares to 9,084,076.

The guidance requires the use of option-pricing models that require the input of highly subjective assumptions, including the option&#8217;s expected life and the price volatility of the underlying stock. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the common stock options, and future dividends, and the resulting charge is expensed using the straight-line attribution method over the vesting period.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Stock compensation expense recognized during the period is based on the value of share-based awards that were expected to vest during the period adjusted for estimated forfeitures.

As of March 31, 2022, we had an accumulated deficit of $71,549,012 and had $7,127,363 in cash. To date we have funded our operations through private and public sales of our securities and will need to raise additional funds in order to execute on our business plan, fully commercialize our TAEUS technology, and generate revenues.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">As of the date of this Quarterly Report, we believe that our cash on hand will be sufficient to fund our current operations into the first half of 2023. We will need additional capital by such time to allow us to continue to execute our commercialization plans. We continue to evaluate and manage our capital needs to support our clinical, regulatory and operational activities, progress EU commercialization, and prepare for U.S. commercialization upon FDA approval of our NAFLD TAEUS device. We are considering potential financing options that may be available to us, including additional sales of our common stock through our At-The-Market Issuance Sales Agreement with Ascendiant Capital Markets, LLC, dated June 21, 2021 (the &#8220;June 2021 ATM Agreement&#8221;). Except for the June 2021 ATM Agreement, we have no commitments to obtain any additional funds, and there can be no assurance funds will be available in sufficient amounts or on acceptable terms. If we are unable to obtain sufficient additional financing in a timely fashion and on terms acceptable to us, our financial condition and results of operations may be materially adversely affected and we may not be able to continue operations or execute our stated commercialization plan.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The consolidated financial statements included in this Form 10-Q have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. As reflected in the accompanying consolidated financial statements, during the three months ended March 31, 2022, we incurred net losses of $2,858,202 and used cash in operations of $3,098,870. While we maintain cash balances in excess of our anticipated needs for cash for the next nine months, it is likely that we will need to raise additional capital prior to any ability to fund operations from revenue generated from the sale of our products. The financial statements do not include any adjustments that might be necessary should we be unable to continue as a going concern.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"><tbody><tr style="height:15px"><td class="hpbhr">&#160;</td></tr><tr style="height:15px"><td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">18</td></tr><tr style="height:15px"><td><p style='page-break-after: always'></p></td></tr><tr style="height:15px"><td><em><a href="#toc">Table of Contents</a></em></td></tr></tbody></table><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Operating Activities</em></strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2022, we used $3,098,870 of cash in operating activities primarily as a result of our net loss of $2,858,202, offset by share-based compensation of $288,537, depreciation expense of $19,038, amortization of right of use assets of $33,179, and net changes in operating assets and liabilities of $(581,422).</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2021, we used $2,923,483 of cash in operating activities primarily as a result of our net loss of $2,269,276, offset by share-based compensation of $321,949, gain on extinguishment of debt of $308,600, stock payable for investor relations of $46,250, depreciation expense of $31,425, amortization of Right of Use assets of $17,449, and net changes in operating assets and liabilities of $(762,680).</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Investing Activities</em></strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2022, we used $89,353 in investing activities related to purchases of equipment.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2021, we used $45,000 in investing activities related to purchases of equipment.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Financing Activities</em></strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2022, our financing activities provided $854,052 in proceeds from issuances of common stock.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">During the three months ended March 31, 2021, our financing activities provided $12,583,920, including $9,798,293 in proceeds from issuance of common stock, and $2,785,627 in proceeds from warrant exercises.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Funding Requirements</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;We have not completed the commercialization of any of our TAEUS technology platform applications.

We do not expect that our existing cash will be sufficient for us to complete the commercialization of our NAFLD TAEUS application or to complete the development of any other TAEUS application and we will need to raise substantial additional capital for those purposes. As a result, we will need to finance our future cash needs through public or private equity offerings, debt financings, corporate collaboration and licensing arrangements or other financing alternatives. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed in the Risk Factors section of our Annual Report on Form 10-K for the period ended December 31, 2021, as filed with the SEC on March 30, 2022.

Additional funds may not be available when we need them on terms that are acceptable to us, or at all. As described below, the COVID-19 pandemic has impacted our business operations to some extent and is expected to continue to do so and, in light of the effect of such pandemic on financial markets, these impacts may include reduced access to capital. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts or perhaps even cease the operation of our business. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaborations and licensing arrangements, it may be necessary to relinquish some rights to our technologies or applications or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"><tbody><tr style="height:15px"><td class="hpbhr">&#160;</td></tr><tr style="height:15px"><td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">19</td></tr><tr style="height:15px"><td><p style='page-break-after: always'></p></td></tr><tr style="height:15px"><td><em><a href="#toc">Table of Contents</a></em></td></tr></tbody></table><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Coronavirus (&#8220;COVID-19&#8221;) Pandemic</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The COVID-19 pandemic has prompted governments and regulatory bodies throughout the world to issue &#8220;stay-at-home&#8221; or similar orders, and enact restrictions on the performance of &#8220;non-essential&#8221; services, public gatherings and travel. These restrictions and other precautionary measures have continued to varying degrees based on local COVID-19 rates and increased infections caused by variants of the coronavirus that causes COVID-19.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Beginning in March 2020, we undertook precautionary measures intended to help minimize the risk of the virus to our employees, including requiring most employees to work remotely, pausing all non-essential travel worldwide for our employees, and limiting employee attendance at industry events and in-person work-related meetings, to the extent those events and meetings are continuing. As a cash-conserving measure taken in light of the adverse economic conditions caused by the COVID-19 pandemic, in April 2020 we reduced the cash salaries of members of management by 33% for the remainder of 2020, including the salaries of our executive officers. In lieu of cash, the Company paid this portion of management salaries in the form of restricted stock units that vested over the remainder of the year. Additionally, we amended our Non-Employee Director Compensation Policy to provide that our non-employee directors&#8217; annual retainers for the second, third and fourth fiscal quarters of 2020 would be paid in in the form of restricted stock units rather than cash. To date we do not believe these actions have had a significant negative impact on our operations. However, these actions or additional measures we may undertake may ultimately delay progress on our developmental goals or otherwise negatively affect our business. In addition, third-party actions taken to contain its spread and mitigate its public health effects of COVID-19 may negatively affect our business.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The COVID-19 pandemic has impacted our clinical trial activities. Patient visits in ongoing clinical trials have been delayed, for example, due to prioritization of hospital resources toward the COVID-19 outbreak, travel restrictions imposed by governments, and the inability to access sites for initiation and monitoring. COVID-19 has also had an effect on the business at the FDA and other health authorities by causing them to reallocate resources to addressing the pandemic, which has resulted in delays of reviews and approvals, including with respect to our NAFLD TAEUS application. Although we believe conditions are improving in both the EU and United States, allowing us to travel and attend trade shows and conferences in-person and for our clinical trials to progress, it is not certain that these improvements will persist and we be restricted from travelling or need to limit in-person meetings in the future, or our clinical trials may need to be delayed in response to adverse developments in the COVID-19 pandemic.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Nasdaq Capital Market Listing</strong></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">On January 5, 2022, the Company received a notification letter from the Listing Qualifications Department of The Nasdaq Stock Market LLC (&#8220;Nasdaq&#8221;) notifying the Company that, because the closing bid price for the Company&#8217;s common stock listed on Nasdaq was below $1.00 for 30 consecutive trading days, the Company no longer meets the minimum bid price requirement for continued listing on The Nasdaq Capital Market under Nasdaq Marketplace Rule 5550(a)(2), requiring a minimum bid price of $1.00 per share (the &#8220;Minimum Bid Price Requirement&#8221;).</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The notification has no immediate effect on the listing of the Company&#8217;s common stock.

If at any time before July 5, 2022, the bid price of the Company&#8217;s common stock closes at or above $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will provide written notification that the Company has achieved compliance with the Minimum Bid Price Requirement.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The notification letter also stated that in the event the Company does not regain compliance with the Minimum Bid Price Requirement by July 5, 2022, the Company may be eligible for an additional 180 calendar days to regain compliance. To qualify for this additional time, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary.

The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of March 31, 2022 and through the date of the filing of this Quarterly Report on Form 10-Q. The accounting matters assessed included, but were not limited to, estimates related to the accounting for potential liabilities and accrued expenses, the assumptions utilized in valuing stock-based compensation issued for services, the realization of deferred tax assets, and assessments of impairment related to long-lived assets. The Company&#8217;s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in additional material impacts to the Company&#8217;s consolidated financial statements in future reporting periods.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Despite the Company&#8217;s efforts, the ultimate impact of COVID-19 on the Company&#8217;s business depends on factors beyond the Company&#8217;s knowledge or control, including the duration and severity of the outbreak, as well as third-party actions taken to contain its spread and mitigate its public health effects. As a result, the Company is unable to estimate the extent to which COVID-19 will negatively impact its financial results or liquidity.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><span style="text-decoration:underline">Principles of Consolidation</span></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company&#8217;s consolidated financial statements include all accounts of the Company and its consolidated subsidiary and/or entities as of reporting period ending date(s) and for the reporting period(s) then ended.

Each January 1 the pool of shares available for issuance under the Omnibus Plan automatically increases by an amount equal to the lesser of (i) the number of shares necessary such that the aggregate number of shares available under the Omnibus Plan equals 25% of the number of fully-diluted outstanding shares on the increase date (assuming the conversion of all outstanding shares of preferred stock and other outstanding convertible securities and exercise of all outstanding options and warrants to purchase shares) and (ii) if the board of directors takes action to set a lower amount, the amount determined by the board.&#160;On January 1, 2022, the pool of shares authorized for issuance under the Omnibus Plan automatically increased by 1,622,848 shares from 7,461,228 shares to 9,084,076.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company records share-based compensation in accordance with the provisions of the Share-based Compensation Topic of the FASB Codification. The guidance requires the use of option-pricing models that require the input of highly subjective assumptions, including the option&#8217;s expected life and the price volatility of the underlying stock. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model, and the resulting charge is expensed using the straight-line attribution method over the vesting period.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Stock compensation expense recognized during the period is based on the value of share-based awards that were expected to vest during the period adjusted for estimated forfeitures. The estimated fair value of grants of stock options and warrants to non-employees of the Company is charged to expense, if applicable, in the financial statements. These options vest in the same manner as the employee options granted under the stock incentive plan as described above.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;<span style="text-decoration:underline">Going Concern</span></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company&#8217;s financial statements are prepared using accounting principles generally accepted in the United States (&#8220;U.S. GAAP&#8221;) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. The Company has limited commercial experience and had a cumulative net loss from inception to March 31, 2022 of $71,549,012. The Company had working capital of $8,761,070&#160;as of March 31, 2022. The Company has not established an ongoing source of revenue sufficient to cover its operating costs and to allow it to continue as a going concern. The accompanying financial statements for the period ended March 31, 2022 have been prepared assuming the Company will continue as a going concern. Although the Company&#8217;s cash resources will likely be sufficient to meet its anticipated needs during the next twelve months, the Company will require additional financing to fund its future planned operations, including research and development and commercialization of its products.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it establishes a revenue stream and becomes profitable. Management&#8217;s plans to continue as a going concern include raising additional capital through sales of equity securities and borrowing. However, management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. As described further below under &#8220;Item 2. Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations&#8221; the COVID-19 pandemic has impacted the Company&#8217;s business operations to some extent and is expected to continue to do so and, in light of the effect of such pandemic on financial markets, these impacts may include reduced access to capital. If the Company is not able to obtain the necessary additional financing on a timely basis, the Company will be required to delay, reduce the scope of, or eliminate one or more of the Company&#8217;s research and development activities or commercialization efforts or perhaps even cease the operation of its business. The ability of the Company to continue as a going concern is dependent upon its ability to successfully secure other sources of financing and attain profitable operations. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><span style="text-decoration:underline">Recent Accounting Pronouncements</span></p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company considered&#160;recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC, did not or in management&#8217;s opinion will not have a material impact on the Company&#8217;s present or future consolidated financial statements.</p><span></span>

The aggregate fair value of these stock options granted by the Company during the three months ended March 31, 2022 was determined to be $899,306&#160;using the Black-Scholes-Merton option-pricing model based on the following assumptions: (i) volatility rate of&#160;74% to&#160;99%, (ii) discount rate of&#160;0%, (iii) zero expected dividend yield, and (iv) expected life of&#160;8-10&#160;years. A summary of option activity under the Company&#8217;s Omnibus Plan as of March 31, 2022, and changes during the year then ended, is presented below:</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times

On July 16, 2019, the Company exercised its option to extend the lease for an additional 5 years past the initial term originally expiring on December 31, 2019.</p>On March 15, 2021, the Company entered into an amendment to the lease, adding approximately 3,248 rentable square feet, increasing the initial monthly rent to $15,452 effective May 2021, and extending the term of the lease to December 31, 2025.&#160; <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company records the lease asset and lease liability at the present value of lease payments over the lease term. The lease typically does not provide an implicit rate; therefore, the Company uses its estimated incremental borrowing rate at the time of lease commencement to discount the present value of lease payments. The Company&#8217;s discount rate for operating leases at March 31, 2022 was&#160;10%. Lease expense is recognized on a straight-line basis over the lease term to the extent that collection is considered probable. As a result, the Company has been recognizing rents as they become payable based on the adoption of ASC Topic 842. The weighted-average remaining lease term is&#160;3.75&#160;years.</p><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&#160;</p><p style="FONT-SIZE: 10pt;

The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of March 31, 2022 and through the date of the filing of this Quarterly Report on Form 10-Q.

Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.

The updated guidance introduces a five-step model to achieve its core principal of the entity recognizing revenue to depict the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. &lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Under ASC Topic 606, in order to recognize revenue, the Company is required to identify an approved contract with commitments to perform respective obligations, identify rights of each party in the transaction regarding goods to be transferred, identify the payment terms for the goods transferred, verify that the contract has commercial substance and verify that collection of substantially all consideration is probable. The adoption of ASC Topic 606 did not have an impact on the Company&#x2019;s operations or cash flows.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;span style="text-decoration:underline"&gt;Research and Development Costs&lt;/span&gt;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;The Company follows FASB Accounting Standards Codification (&#x201c;ASC&#x201d;) Subtopic 730-10, &#x201c;Research and Development&#x201d;.

Basic earnings (loss) per share is computed by dividing the net income (loss) attributable to the common stockholders (the numerator) by the weighted average number of shares of common stock outstanding (the denominator) during the reporting periods. Diluted loss per share is computed by increasing the denominator by the weighted average number of additional shares that could have been outstanding from securities convertible into common stock (using the &#x201c;treasury stock&#x201d; method), unless their effect on net loss per share is anti-dilutive. There were&#160;10,564,415&#160;and&#160;7,848,899&#160;potentially dilutive shares, which include outstanding common stock options, warrants, and convertible notes, as of March 31, 2022 and&#160;December 31, 2021,&#160;respectively.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt;

the Company measures certain financial instruments at fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Each January 1 the pool of shares available for issuance under the Omnibus Plan automatically increases by an amount equal to the lesser of (i) the number of shares necessary such that the aggregate number of shares available under the Omnibus Plan equals 25% of the number of fully-diluted outstanding shares on the increase date (assuming the conversion of all outstanding shares of preferred stock and other outstanding convertible securities and exercise of all outstanding options and warrants to purchase shares) and (ii) if the board of directors takes action to set a lower amount, the amount determined by the board.&#160;On January 1, 2022, the pool of shares authorized for issuance under the Omnibus Plan automatically increased by 1,622,848 shares from 7,461,228 shares to 9,084,076.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company records share-based compensation in accordance with the provisions of the Share-based Compensation Topic of the FASB Codification. The guidance requires the use of option-pricing models that require the input of highly subjective assumptions, including the option&#x2019;s expected life and the price volatility of the underlying stock. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model, and the resulting charge is expensed using the straight-line attribution method over the vesting period.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Stock compensation expense recognized during the period is based on the value of share-based awards that were expected to vest during the period adjusted for estimated forfeitures. The estimated fair value of grants of stock options and warrants to non-employees of the Company is charged to expense, if applicable, in the financial statements. These options vest in the same manner as the employee options granted under the stock incentive plan as described above.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;span style="text-decoration:underline"&gt;Going Concern&lt;/span&gt;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company&#x2019;s financial statements are prepared using accounting principles generally accepted in the United States (&#x201c;U.S. GAAP&#x201d;) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. The Company has limited commercial experience and had a cumulative net loss from inception to March 31, 2022 of $71,549,012. The Company had working capital of $8,761,070&#160;as of March 31, 2022. The Company has not established an ongoing source of revenue sufficient to cover its operating costs and to allow it to continue as a going concern. The accompanying financial statements for the period ended March 31, 2022 have been prepared assuming the Company will continue as a going concern. Although the Company&#x2019;s cash resources will likely be sufficient to meet its anticipated needs during the next twelve months, the Company will require additional financing to fund its future planned operations, including research and development and commercialization of its products.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it establishes a revenue stream and becomes profitable. Management&#x2019;s plans to continue as a going concern include raising additional capital through sales of equity securities and borrowing. However, management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. As described further below under &#x201c;Item 2. Management&#x2019;s Discussion and Analysis of Financial Condition and Results of Operations&#x201d; the COVID-19 pandemic has impacted the Company&#x2019;s business operations to some extent and is expected to continue to do so and, in light of the effect of such pandemic on financial markets, these impacts may include reduced access to capital. If the Company is not able to obtain the necessary additional financing on a timely basis, the Company will be required to delay, reduce the scope of, or eliminate one or more of the Company&#x2019;s research and development activities or commercialization efforts or perhaps even cease the operation of its business. The ability of the Company to continue as a going concern is dependent upon its ability to successfully secure other sources of financing and attain profitable operations. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;span style="text-decoration:underline"&gt;Recent Accounting Pronouncements&lt;/span&gt;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company considered&#160;recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC, did not or in management&#x2019;s opinion will not have a material impact on the Company&#x2019;s present or future consolidated financial statements.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of March 31, 2022 and through the date of the filing of this Quarterly Report on Form 10-Q.

Each January 1 the pool of shares available for issuance under the Omnibus Plan automatically increases by an amount equal to the lesser of (i) the number of shares necessary such that the aggregate number of shares available under the Omnibus Plan equals 25% of the number of fully-diluted outstanding shares on the increase date (assuming the conversion of all outstanding shares of preferred stock and other outstanding convertible securities and exercise of all outstanding options and warrants to purchase shares) and (ii) if the board of directors takes action to set a lower amount, the amount determined by the board.&#160;On January 1, 2022, the pool of shares authorized for issuance under the Omnibus Plan automatically increased by 1,622,848 shares from 7,461,228 shares to 9,084,076.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company records share-based compensation in accordance with the provisions of the Share-based Compensation Topic of the FASB Codification. The guidance requires the use of option-pricing models that require the input of highly subjective assumptions, including the option&#x2019;s expected life and the price volatility of the underlying stock. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model, and the resulting charge is expensed using the straight-line attribution method over the vesting period.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Stock compensation expense recognized during the period is based on the value of share-based awards that were expected to vest during the period adjusted for estimated forfeitures.

These options vest in the same manner as the employee options granted under the stock incentive plan as described above.&lt;/p&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

The Company has limited commercial experience and had a cumulative net loss from inception to March 31, 2022 of $71,549,012. The Company had working capital of $8,761,070&#160;as of March 31, 2022. The Company has not established an ongoing source of revenue sufficient to cover its operating costs and to allow it to continue as a going concern. The accompanying financial statements for the period ended March 31, 2022 have been prepared assuming the Company will continue as a going concern. Although the Company&#x2019;s cash resources will likely be sufficient to meet its anticipated needs during the next twelve months, the Company will require additional financing to fund its future planned operations, including research and development and commercialization of its products.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it establishes a revenue stream and becomes profitable. Management&#x2019;s plans to continue as a going concern include raising additional capital through sales of equity securities and borrowing. However, management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. As described further below under &#x201c;Item 2. Management&#x2019;s Discussion and Analysis of Financial Condition and Results of Operations&#x201d; the COVID-19 pandemic has impacted the Company&#x2019;s business operations to some extent and is expected to continue to do so and, in light of the effect of such pandemic on financial markets, these impacts may include reduced access to capital. If the Company is not able to obtain the necessary additional financing on a timely basis, the Company will be required to delay, reduce the scope of, or eliminate one or more of the Company&#x2019;s research and development activities or commercialization efforts or perhaps even cease the operation of its business. The ability of the Company to continue as a going concern is dependent upon its ability to successfully secure other sources of financing and attain profitable operations. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.&lt;/p&gt;</us-gaap:SubstantialDoubtAboutGoingConcernTextBlock>

On July 16, 2019, the Company exercised its option to extend the lease for an additional 5 years past the initial term originally expiring on December 31, 2019.&lt;/p&gt;On March 15, 2021, the Company entered into an amendment to the lease, adding approximately 3,248 rentable square feet, increasing the initial monthly rent to $15,452 effective May 2021, and extending the term of the lease to December 31, 2025.&#160; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company records the lease asset and lease liability at the present value of lease payments over the lease term. The lease typically does not provide an implicit rate; therefore, the Company uses its estimated incremental borrowing rate at the time of lease commencement to discount the present value of lease payments. The Company&#x2019;s discount rate for operating leases at March 31, 2022 was&#160;10%. Lease expense is recognized on a straight-line basis over the lease term to the extent that collection is considered probable. As a result, the Company has been recognizing rents as they become payable based on the adoption of ASC Topic 842. The weighted-average remaining lease term is&#160;3.75&#160;years.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p
