We have described below a number of uncertainties and risks which, in addition to uncertainties and risks presented elsewhere in this Annual Report, may adversely affect our business, operating results and financial condition.  The uncertainties and risks enumerated below as well as those presented elsewhere in this Annual Report should be considered carefully in evaluating us, our business and the value of our securities. The following important factors, among others, could cause our actual business, financial condition and future results to differ materially from those contained in forward-looking statements made in this Annual Report or presented elsewhere by management from time to time.

Risks Related to our Financial Position and Need to Raise Additional Capital

We were forced to curtail our operations due to a lack of operating capital and we will not be able to continue as a going concern if we do not obtain additional financing. 

Since our inception, we have funded our operations through the sale of our securities. Our cash and restricted cash balances at December 31, 2019 was approximately $23,000. In February 2018 we were forced to curtail our operations. Despite raising $250,000 in gross proceeds through the sale of convertible debentures in March 2020, our ability to continue as a going concern is still wholly dependent upon obtaining sufficient capital to fund our operations. We have no committed sources of additional capital and our access to capital funding is always uncertain. Accordingly, despite our ability to secure capital in the past, we cannot assure you that we will be able to secure additional capital through financing transactions, including issuance of debt, or through other means such as the licensing of our technology or grants. In the event that we are not able to secure additional funding, we may be forced to curtail operations, delay or stop ongoing clinical trials, cease operations altogether or file for bankruptcy.

Our auditors have expressed substantial doubt about our ability to continue as a going concern.

Our auditors’ report on our December 31, 2019 financial statements expressed an opinion that our capital resources as of the date of their audit report were not sufficient to sustain operations or complete our planned activities for the upcoming year unless we raised additional funds. Our current cash level raises substantial doubt about our ability to continue as a going concern past the third quarter of 2020. If we do not obtain additional funds by such time, we may no longer be able to continue as a going concern and will cease operation which means that our shareholders will lose their entire investment.

Risks Relating to Our Stage of Development and Business

If we are unable to successfully build a new management team and secure additional members and employees, our business could be harmed.

On July 15, 2019, Christopher Lowe, our chief executive officer, president and principal accounting officer resigned. In February 2018, Ronald Shazer, MD, resigned as our chief medical officer. Effective July 26, 2019, we appointed Michael Cain as our interim Chief Executive Officer and Chief Financial Officer. We will need to continue to augment senior management as well as additional personnel to execute our business plan and grow our business. Our success depends largely on the development and execution of our business strategy by our senior management team. The recent transitions in our executive team may be disruptive to our business, and if we are unable to manage an orderly transition, our business may be adversely affected. Additionally, since our management team consists of only one individual, Mr. Cain, the loss of Mr. Cain would likely harm our ability to implement our business strategy and respond to the rapidly changing market conditions in which we operate. There may be a limited number of persons with the requisite skills to serve in these positions, and we cannot assure you that we would be able to identify or employ such qualified personnel on acceptable terms, if at all. Additionally, we cannot assure you that management will succeed in working together as a team. In the event that we are unsuccessful, our business and prospects could be harmed.  

We are an early-stage company, have no product revenues, are not profitable and may never be profitable.

From inception through December 31, 2019, we have raised approximately $37.2 million through the sale of our securities and exercise of outstanding warrants. During this same period, we have recorded an accumulated deficit of approximately $60.7 million. Our net losses for the two most recent fiscal years ended December 31, 2019 and 2018 were $934,000 and $12,000, respectively. Our increase in net losses is primarily the result of decreases in gains from the change in fair value of our derivative instruments and gains on conversions of debt, and increases in professional fees and interest expense, all partially offset by a decrease in compensation expense. None of our products in development have received approval from the United States Food and Drug Administration or FDA, or other regulatory authorities; we have no sales and have never generated revenues nor do we expect to for the foreseeable future. We have currently curtailed our pre-clinical and clinical trials related to mipsagargin and are currently focusing our efforts on the development of our adenosine receptor modulators. We expect to incur significant operating losses for the foreseeable future as we continue the research, pre-clinical and clinical development of our product candidates as well as the possible in-licensing of additional clinical and pre-clinical assets. Accordingly, we will need additional capital to fund our continuing operations and any expansion plans. Since we do not generate any revenue, the most likely sources of such additional capital include the sale of our securities, a strategic licensing collaboration transaction or joint venture involving the rights to one or more of our product candidates, or from grants. To the extent that we raise additional capital by issuing equity securities, our stockholders are likely to experience dilution with regard to their percentage ownership of the company, which may be significant. If we raise additional funds through collaborations or licensing arrangements, we may be required to relinquish some or all the rights to our technologies, product candidates, or grant licenses on terms that are not favorable to us. If we raise additional capital by incurring debt, we could incur significant interest expense and become subject to covenants that could affect the manner in which we conduct our business, including securing such debt obligations with our assets.

Our product candidates are at various stages of early development and significant financial resources are required to develop commercially viable products and obtain regulatory approval to market and sell such products. We will need to devote significantly more research and development efforts, financial resources and personnel to develop commercially viable products and obtain regulatory approvals. We may encounter hurdles and unexpected issues as we proceed in the development of our other product candidates. While initial data from our research appear promising, the outcome of the pre-clinical and development work is uncertain and future trials may ultimately be unsuccessful. If we fail to develop and successfully commercialize our product candidates, our business may be materially harmed and could fail.

We have a limited operating history as a company, and may not be able to effectively operate our business.

Our limited staff and operating history means that there is a high degree of uncertainty regarding our ability to:

No assurances can be given as to exactly when, if at all, we will be able to fully develop, and take the necessary steps to derive any revenues from our proposed product candidates.

Raising capital may be difficult as a result of our history of losses and limited operating history in our current stage of development.

When making investment decisions, investors typically look at a company’s management, earnings and historical performance in evaluating the risks and operations of the business and the business’s future prospects. Our history of losses, new senior management team and relatively limited operating history in our current stage of development makes such evaluation, as well as any estimation of our future performance, substantially more difficult. As a result, investors may be unwilling to invest in us or on terms or conditions which are acceptable. If we are unable to secure additional financing, we may need to materially scale back our business plan and/or operations or cease operations altogether. 

A pandemic, epidemic or outbreak of an infectious disease in the markets in which we operate or that otherwise impacts our facilities or advisors could adversely impact our business.

If a pandemic, epidemic, or outbreak of an infectious disease including the recent outbreak of respiratory illness caused by a novel coronavirus (COVID-19) or other public health crisis were to affect our facilities or those of our suppliers, our business could be adversely affected. A pandemic typically results in social distancing, travel bans and quarantine, and this may limit access to our facilities, management, support staff and professional advisors. These factors, in turn, may not only materially impact our operations and financial condition, but our overall ability to react timely to mitigate the impact of this event. Also, it may hamper our efforts to comply with our filing obligations with the Securities and Exchange Commission.

Business or economic disruptions or global health concerns could seriously harm our development efforts and increase our costs and expenses.

Broad-based business or economic disruptions could adversely affect our ongoing or planned research and development activities. For example, in November 2019 an outbreak of a novel strain of coronavirus originated in Wuhan, China, and has since spread around the world, including to the United States. To date, this outbreak has already resulted in extended shutdowns of many businesses around the world, including in the United States. Global health concerns, such as coronavirus, could also result in social, economic, and labor instability in the countries in which we or the third parties with whom we engage operate. We cannot presently predict the scope, severity and longevity of any potential business shutdowns or disruptions, but if we or any of the third parties with whom we engage or plan to engage, including the suppliers, clinical trial sites, regulators and other third parties with whom we conduct business or plan to conduct business, were to experience shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively impacted. It is also possible that global health concerns such as this one could disproportionately impact the hospitals and clinical sites in which we conduct or plan to conduct any of our clinical trials, which could have a material adverse effect on our business and our results of operation and financial condition. 

Risks Related to Commercialization

The market for our proposed products is rapidly changing and competitive.

The pharmaceutical and biotechnology industries are subject to rapid and substantial technological change and innovation. Developments by others may render our proposed products noncompetitive or obsolete, or we may be unable to keep pace with technological developments and other market factors. Competition from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase.

As a pre-revenue company, our resources are limited and we may experience challenges inherent in the early development of novel therapeutics. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competition. Some of these technologies may have an entirely different approach or means of accomplishing similar therapeutic efforts compared to our proposed products. Our competitors may develop therapies that are safer, more effective and less costly than our proposed products and therefore, present a serious competitive threat to us.

The acceptance of therapies that are alternatives to ours may limit market acceptance of our proposed products, even if commercialized. Many of our targeted diseases and conditions can also be treated by other medications and treatments. These treatments may be widely accepted in medical communities and have a longer history of use. The established use of other competing therapies may limit the potential for our proposed products, even if commercialized.

Our proposed products may not be accepted by the healthcare community.

Our proposed products, if approved for marketing, may not achieve market acceptance by the healthcare community since hospitals, physicians, patients or the medical community in general may decide not to utilize them. We are attempting to develop products that are likely to be first approved for marketing as a treatment for late stage cancer where there is no truly effective standard of care. If approved for use in late stage cancer, our proposed products might then be evaluated in earlier stages where they could represent a substantial departure from established treatment methods and would most likely compete with a number of more conventional drugs and therapies which are manufactured and marketed by major pharmaceutical companies. It is too early in the development cycle of our proposed products for us to predict our major competitors. The degree of market acceptance of our products, if developed, will depend on a number of factors, including but not limited to:

If the healthcare community does not accept our products, our business could be materially harmed.

Our potential competitors in the biotechnology and pharmaceutical industries have significantly greater resources than we have.

We compete against numerous companies, many of which have substantially greater resources than we have. Several such competitors have research programs and/or efforts to treat the same diseases we target. Companies such as Roche, Novartis, Celgene, Merck & Co., Inc., Johnson & Johnson, and Sanofi S.A., as well as others, have substantially greater financial, research, manufacturing and marketing resources than we do. As a result, such competitors may find it easier to compete in our industry and bring competing products to market.

Risks Related to the Development and Manufacturing of Our Product Candidates

We intend to rely exclusively upon third-party FDA-regulated manufacturers and suppliers for our proposed products.

We currently have no internal manufacturing capability, and intend to rely exclusively on FDA-approved licensees, strategic partners or third party contract manufacturers or suppliers for the foreseeable future. Because manufacturing facilities are subject to regulatory oversight and inspection, the failure of any of our third-party FDA regulated manufactures or suppliers to comply with regulatory requirements could result in material manufacturing delays and product shortages, which could delay or otherwise negatively impact our clinical trials and product development plans. Should we be forced to manufacture our proposed products, we cannot give any assurance that we would be able to develop internal manufacturing capabilities or secure third party suppliers for raw materials. In the event that we seek third party suppliers or alternative manufacturers, they may require us to purchase a minimum amount of materials or could require other unfavorable terms. Any such event could materially impact our business prospects and could delay the development of our proposed products. Moreover, we cannot give any assurance that the contract manufacturers or suppliers that we select will be able to supply our products in a timely or cost effective manner or in accordance with applicable regulatory requirements or our own specifications.

We may not be able to establish or maintain the third-party relationships that are necessary to develop or potentially commercialize our product candidates.

As needed, we plan to rely heavily on third party collaborators, partners, licensees, clinical research organizations, clinical investigators, vendors or other third parties to support our research and development efforts and to conduct clinical trials for our product candidates. We cannot guarantee that we will be able to successfully negotiate agreements for, or maintain relationships with, these third parties on a commercially reasonable basis, if at all. Additionally, to commercialize our proposed products, we intend to rely on third party licensees or the outright sale of our proposed products to pharmaceutical partner(s). If we fail to establish or maintain such third-party relationships as anticipated, our business could be adversely effected.

We are dependent upon third parties to develop our product candidates, and such parties are, to some extent, outside of our control.

We depend and plan to depend upon independent contract research organizations, investigators and collaborators, such as universities and medical institutions, to conduct our pre-clinical and clinical studies. These individuals and/or entities are not our employees and we cannot control the amount or timing of resources that they devote to our programs. These third parties may not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such programs ourselves. If these third parties fail to devote sufficient time and resources to our programs, or if their performance is substandard, the development of our drug candidates and corresponding FDA approval could be delayed or fail entirely.

Our therapeutic compounds may not be able to be manufactured profitably on a large enough scale to support commercialization.

To date, prior to our curtailment of operations, our therapeutic compounds have only been manufactured at a scale which is adequate to supply our research activities and early-stage clinical trials. There can be no assurance that the procedures currently used to manufacture our therapeutic compounds will work at a scale which is adequate for commercial needs. In the event our therapeutic compounds cannot be manufactured in sufficient quantities for commercialization, our future prospects could be significantly impacted and our financial prospects would be materially harmed.

Risks Relating to our Intellectual Property

Our competitive position is dependent on our intellectual property and we may not be able to withstand challenges to our intellectual property rights.

We rely on our intellectual property, including our issued and applied for U.S. and foreign patents as well as our licenses, as the foundation of our business. If our intellectual property rights are challenged, no assurances can be given that our patents or licenses would survive claims alleging invalidity or infringement on other patents and/or licenses. In addition, disputes may arise regarding inventorship of our intellectual property. It is possible that our intellectual property may be infringing upon existing patents that we are not currently unaware of. As the number of participants in the marketplace grows, the possibility of patent infringement claims against us increases. It is difficult, if not impossible, to determine how such disputes would be resolved. Furthermore, because of the substantial amount of discovery required in connection with patent litigation, there is a risk that some of our confidential information could be required to be publicly disclosed. Any litigation claims against us may cause us to incur substantial costs and could place a significant strain upon our financial resources, divert the attention of management or restrict our core business or result in the public disclosure of confidential information.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to protect our rights to, or use of, our technology.

Some or all of our patent applications may not issue as patents, or the claims of any issued patents may not afford meaningful protection for our technologies or products. In addition, patents issued to us or our licensors, if any, may be challenged and subsequently narrowed, invalidated or circumvented. Patent litigation is widespread in the biotechnology industry and could harm our business. Litigation might be necessary to protect our patent position or to determine the scope and validity of third-party proprietary rights. If we choose to go to court to stop someone else from using the inventions claimed in our patents, that individual or company would have the right to ask the court to rule that such patents are invalid and/or should not be enforced against that third party. These lawsuits are expensive and we may not have the required resources to pursue such litigation or to protect our patent rights. In addition, there is a risk that the court might decide that these patents are not valid and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity of these patents is upheld, the court could refuse to stop the other party on the ground that such other party’s activities do not infringe on our rights contained in these patents.

Furthermore, a third party may claim that we are using inventions covered by their patent rights and may go to court to stop us from engaging in our normal operations and activities, including making or selling our product candidates. These lawsuits are costly and could materially increase our operating expenses and divert the attention of managerial and technical personnel. There is a risk that a court would decide that we are infringing the third party’s patents and would order us to stop the activities covered by the patents. In addition, there is a risk that a court would order us to pay the other party damages for having violated the other party’s patents. The biotechnology industry has produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform.  

Because some patent applications in the United States may be maintained in secrecy until the patents are issued, patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, and publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications covering technology similar to ours. Any such patent application may have priority over our patent applications and could further require us to obtain rights to issued patents covering such technologies.

If another party has filed a United States patent application on inventions similar to ours, we may have to participate in an interference or other proceeding in the U.S. Patent and Trademark Office, or the PTO, or a court to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful, resulting in a loss of our United States patent position with respect to such inventions.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the capital necessary to continue our operations.

Obtaining and maintaining our patent protection depends upon compliance with various procedural, documentary, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

The PTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case.

We may not be able to adequately protect our intellectual property.

We rely in part on trade secret protection in order to protect our proprietary trade secrets and unpatented know-how. However, trade secrets are difficult to protect, and we cannot be certain that others do not develop the same or similar technologies on their own. Additionally, research with regard to our technologies has been performed in countries outside of the United States, and we also anticipate conducting joint ventures, collaborations and future clinical trials outside the US. The laws in some of these countries may not provide protection for our trade secrets and intellectual property. We have taken steps, including entering into confidentiality agreements with our employees, consultants, service providers, and potential strategic partners to protect our trade secrets and unpatented know-how. These agreements generally require that the other party keep confidential and not disclose to third parties all confidential information developed by the party or made known to the party by us during the course of the party’s relationship with us. We also typically obtain agreements from these parties which provide that inventions conceived by the party in the course of rendering services to us are our property. However, these agreements may not be honored, including in foreign countries in which we conduct research, and may not effectively assign intellectual property rights to us. Enforcing a claim that a party illegally obtained and is using our trade secrets or know-how is difficult, expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets or know-how. The failure to obtain or maintain trade secret protection could adversely affect our competitive position.

We may be subject to claims that our employees or consultants have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industries, we employ and hire individuals and/or entities who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although no claims against us are currently pending, we may be subject to claims that these individuals, entities or that we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Risks Relating to Marketing Approval and Government Regulations  

Data obtained from clinical trials are susceptible to varying interpretations and may not be sufficient to support approval of our proposed products by the FDA.

The design of our potential clinical trials will be based on many assumptions about the expected effect of our product candidates and if those assumptions are incorrect, our potential clinical trials may not produce statistically significant results. Preliminary results may not be confirmed on full analysis of the detailed results of early clinical trials. Data already obtained, or in the future obtained, from pre-clinical studies and clinical trials do not necessarily predict the results that may be obtained from later trials. Moreover, pre-clinical and clinical data are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to adequately demonstrate the safety and effectiveness of a proposed formulation or product under development could delay or prevent regulatory clearance of the potential drug. Our products may not prove to be safe and effective in clinical trials and may not meet all regulatory requirements needed to receive regulatory approval. While data from our completed trials appear promising, the outcome of the current trials is uncertain and these trials or future trials may ultimately be unsuccessful. Our clinical trials may among other things, not demonstrate sufficient levels of safety and efficacy necessary to obtain the requisite regulatory approvals for our drugs, and thus our proposed drugs may not be approved for marketing.

Our proposed products may not receive FDA or other regulatory approvals.

The FDA and comparable government agencies in foreign countries impose substantial regulations on the manufacture and marketing of pharmaceutical products through expensive, lengthy and detailed laboratory, pre-clinical and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Satisfaction of these regulations typically takes several years or more and varies substantially based upon the type, complexity and novelty of the proposed product. Our proposed products are subject to extensive regulation and/or acceptance by numerous governmental authorities in the United States, including the FDA, and authorities in other countries. Most of our proposed products will require governmental approval before they can be commercialized. Our failure to receive the regulatory approvals in the United States or foreign countries will materially impact our business.

Our proposed products may not have favorable results in clinical trials or receive regulatory approval.

Encouraging results from our studies to date should not be relied upon as evidence that our planned pre-clinical and clinical trials will ultimately be successful or our products approved for marketing. Even though the results of our studies to date seem promising, we will be required to demonstrate through further pre-clinical and clinical trials that our product candidates are safe and effective for use in a diverse population before we can seek regulatory approvals for their commercial sale. There is typically an extremely high rate of attrition from the failure of product candidates as they proceed through clinical trials. If any product candidate fails to demonstrate sufficient safety and efficacy in any clinical trial, then we could experience potentially significant delays in, or be required to abandon, development of that product candidate. While initial data from our preliminary studies appear promising, the outcome of any clinical trials is uncertain and such trials or future trials may ultimately be unsuccessful.

If users of our proposed products are unable to obtain adequate reimbursement from third-party payors, market acceptance of our proposed products may be limited and we may not achieve revenues or profits.

The continuing efforts of governments, insurance companies, health maintenance organizations and other payers of healthcare costs to contain or reduce costs of health care may affect our future revenues and profitability as well as the future revenues and profitability of our potential customers, suppliers and collaborative partners in addition to the availability of capital. In other words, our ability to commercialize our proposed products depends in large part on the extent to which appropriate reimbursement levels for the cost of our proposed formulations, products and related treatments are obtained by the health care providers of these products and treatments. At this time, we cannot predict the precise impact that recently adopted or future laws will have on these reimbursement levels.

We may be unable to comply with our reporting and other requirements under federal securities laws.

The Sarbanes-Oxley Act of 2002, as well as related new rules and regulations implemented by the United States Securities and Exchange Commission, or SEC, and the Public Company Accounting Oversight Board, require changes in the corporate governance practices and financial reporting standards for public companies. These laws, rules and regulations, including compliance with Section 404 of the Sarbanes-Oxley Act of 2002 relating to internal control over financial reporting, would be expected to materially increase the Company’s legal and financial compliance costs and make some activities more time-consuming and more burdensome. Presently we qualify as a non-accelerated filer. Accordingly, we are exempt from the requirements of Section 404(b) and our independent registered public accounting firm is not required to audit the design and operating effectiveness of our internal controls and management’s assessment of the design and the operating effectiveness of such internal controls. In the event that we become an accelerated filer, we will be required to expend substantial capital in connection with compliance.

We do not have effective internal controls over our financial reporting.

Because of our limited resources, management has concluded that our internal control over financial reporting may not be effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Effective internal controls over financial reporting and disclosure controls and procedures are necessary for us to provide reliable financial and other reports and effectively prevent fraud. If we cannot provide reliable financial or SEC reports or prevent fraud, investors may lose confidence in our SEC reports, our operating results and the trading price of our common stock could suffer materially and we may become subject to litigation.

Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses and will divert time and attention away from revenue generating activities.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002 and related SEC regulations, have created uncertainty for public companies and significantly increased the costs and risks associated with accessing the public markets and public reporting. Our management team invests significant time and financial resources to comply with both existing and evolving standards for public companies, which will lead to increased general and administrative expenses and a diversion of management time and attention from developing our business to compliance activities which could have an adverse effect on our business.

Risks Relating to our Securities

Our common stock price may be particularly volatile because of our stage of development and business.

The market prices for the securities of biotechnology and pharmaceutical companies in general, and early-stage drug development companies in particular, such as ours, have been highly volatile and may continue to be highly volatile in the future. The following may have a significant impact on the market price of our common stock:

Broad market fluctuations may cause the market price of our common stock to decline substantially. Additionally, fluctuations in the trading price or liquidity of our common stock may materially and adversely affect, among other things, the interest of investors to purchase our common stock on the open market and, generally, our ability to raise capital.

Our board of directors has broad discretion to issue additional securities, in the event that we have adequate authorized capital to issue such securities.

We are authorized under our certificate of incorporation to issue up to 150,000,000 shares of common stock and 30,000,000 “blank check” shares of preferred stock. Shares of our blank check preferred stock provide the board of directors with broad authority to determine voting, dividend, conversion, and other rights. As of May 1, 2020, we have issued and outstanding 150,000,000 shares of common stock and, accordingly, no additional shares of common stock reserved for future grants under our equity compensation plans and for issuances upon the exercise or conversion of currently outstanding shares of preferred stock, options, warrants and other convertible securities will be available until such time as we complete a reverse stock split or authorize additional shares. As of May 1, 2020, we have issued 1,853 shares of Series A 0% Convertible Preferred Stock, of which 133.8125 are outstanding, 1,000 shares of Series B 0% Convertible Preferred Stock, of which 71 are outstanding, 290.43148 shares of Series C 0% Convertible Preferred Stock, that are all outstanding, and 5,000 shares of Series D 0% Convertible Preferred Stock, all of which are outstanding. Accordingly, we are entitled to issue no additional shares of common stock, and 29,994,505 additional shares of “blank check” preferred stock. Our board may generally issue those common and preferred shares, or convertible securities to purchase those shares, without further approval by our shareholders. Any additional preferred shares we may issue could have such rights, preferences, privileges, and restrictions as may be designated from time-to-time by our board, including preferential dividend rights, voting rights, conversion rights, redemption rights and liquidation provisions.

It is likely that we will issue a large amount of additional securities to raise capital in order to further our business plans. It is also likely that we will issue a large amount of additional securities to directors, officers, employees and consultants as compensatory grants in connection with their services, both in the form of stand-alone grants or under our various stock plans. Any issuances could be made at a price that reflects a discount to, or a premium from, the then-current market price of our common stock. These issuances would dilute the percentage ownership interest of our current shareholders, which would have the effect of reducing your influence on matters on which our stockholders vote, and might dilute the net tangible book value per share of our common stock.

We currently do not have enough authorized shares of common stock for additional issuances. In order to authorize additional shares the Company will be required to authorize additional common shares by obtaining votes from our shareholders sufficient to amend our certificate of incorporation or effect a reverse stock split of our common shares.

Future sales of our common stock could cause our stock price to fall.

Transactions that result in a large amount of newly issued shares become readily tradable, or other events that cause current stockholders to sell shares, could place downward pressure on the trading price of our common stock. In addition, the lack of a robust trading market may require a stockholder who desires to sell a large number of shares of common stock to sell the shares in increments over time to mitigate any adverse impact of the sales on the market price of our stock. If our stockholders sell, or the market perceives that our stockholders intend to sell for various reasons, substantial amounts of our common stock in the public market, including shares issued upon the exercise of outstanding options or warrants, the market price of our common stock could fall. Sales of a substantial number of shares of our common stock may make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate. We may become involved in securities class action litigation that could divert management’s attention and harm our business.

As of May 1, 2020, we had 150,000,000 shares of common stock, 1,853 shares of Series A 0% Convertible Preferred Stock issued and 133.8125 Series A 0% Convertible Preferred Stock outstanding, 1,000 shares of Series B 0% Convertible Preferred Stock issued and 71 Series B 0% Convertible Preferred Stock outstanding, 290.43148 shares of Series C 0% Convertible Preferred Stock issued and outstanding, and 5,000 shares of Series D 0% Convertible Preferred Stock issued and outstanding. We additionally have issued an aggregate of $3,891,048 of senior convertible debentures and convertible notes that are convertible into common stock at any time, of which $2,624,346 is outstanding. Substantially all of the common shares and common shares underlying the Series A 0% Convertible Preferred, Series B 0% Convertible Preferred, Series C 0% Convertible Preferred, and Series D 0% Convertible Preferred are available for public sale, subject in some cases to volume and other limitations or delivery of a prospectus. As of May 1, 2020, we were obligated to reserve for issuance (i) 13,129 shares of our common stock issuable upon the conversion of 133.8125 shares of Series A 0% Convertible Preferred Stock including an additional number of common shares we are contractually obligated to reserve pursuant to our December 2015 offering; (ii) 14,200,000 shares of our common stock issuable upon the conversion of 71 shares of Series B 0% Convertible Preferred Stock including an additional number of common shares we are contractually obligated to reserve pursuant to our December 2016 offering; (iii) 1,523,452 shares of our common stock issuable upon the conversion of 290.43148 shares of Series C 0% Convertible Preferred Stock including an additional number of common shares we are contractually obligated to reserve pursuant to our March 2017 offering, (iv) 40,000 shares of common stock issuable upon the conversion of 5,000 shares of Series D 0% Convertible Preferred Stock, (v) 168,853 shares of our common stock issuable upon exercise of outstanding warrants at a weighted average exercise price of $42.03 per share, including an additional number of common shares we are contractually obligated to reserve pursuant to our December 2015 offering, December 2016 offering and March 2017 offering, (vi) 6,598 shares of our common stock issuable upon exercise of outstanding stock options under our equity compensation plans at a weighted average exercise price of $60.99 per share and (vii) 359,555,965 shares of our common stock issuable upon conversion of our outstanding convertible notes/debentures. Subject to applicable vesting requirements and holding periods, upon conversion or exercise of the outstanding convertible notes, warrants and options, the underlying shares may be resold into the public market. Notwithstanding the foregoing, none of the shares of common stock underlying these convertible securities may be converted or exercised given that we have no shares of common stock available under our certificate of incorporation. We cannot predict if future issuances or sales of our common stock, or the availability of our common stock for sale, would harm the market price of our common stock or our ability to raise capital. Notwithstanding the foregoing, we currently do not have adequate authorized shares available for issuance pursuant to our convertible securities as of May 1, 2020.

The market for our common stock has been illiquid and our investors may be unable to sell their shares.

Our common stock trades with limited volume on the pink sheets of the OTC Markets Group Inc. Accordingly, although a limited public market for our common stock exists, it is still relatively illiquid compared to that of a seasoned issuer. Prior to making an investment in our securities, you should consider the limited market for our common stock. No assurances can be given that the trading volume of our common stock will increase or that a liquid public market for our securities will ever materialize.

We have not paid cash dividends in the past and do not expect to pay cash dividends in the foreseeable future.

We have never paid cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if the market price of our common stock appreciates.

Provisions of Delaware law and executive employment agreements may prevent or delay a change of control, which could depress the trading price of our common stock.

We are subject to the Delaware anti-takeover laws regulating corporate takeovers. These anti-takeover laws prevent Delaware corporations from engaging in a merger or sale of more than 10% of its assets with any stockholder, including all affiliates and associates of the stockholder, who owns 15% or more of the corporation’s outstanding voting stock, for three years following the date that the stockholder acquired 15% or more of the corporation’s assets unless:

A Delaware corporation may opt out of the Delaware anti-takeover laws if its certificate of incorporation or bylaws so provides. We have not opted out of the provisions of the anti-takeover laws. As such, these laws could prohibit or delay mergers or other takeover or change of control transactions and may discourage attempts by other companies to acquire us.

In addition, employment agreements with certain executive officers provide for the payment of severance and accelerated vesting of options and restricted stock in the event of termination following a change of control. These provisions could have the effect of discouraging potential takeover attempts even if it would be beneficial to shareholders.

Our certificate of incorporation and bylaws contain provisions that could discourage a third-party from acquiring us.

Our certificate of incorporation and bylaws, as applicable, among other things (i) provide our board with the ability to alter the bylaws without stockholder approval and (ii) provide that vacancies on our board of directors may be filled by a majority of directors in office. These provisions, while designed to reduce vulnerability to an unsolicited acquisition proposal, and to discourage certain tactics used in proxy fights, may negatively impact a third-party’s decision to acquire us even if it would be beneficial to shareholders.

If securities or industry analysts do not publish research or reports or if they publish unfavorable research or reports, an active market for our common stock may not develop and the price of our common stock could decline.

We are a small company which is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume. Even if we come to the attention of such persons, they may be reluctant to follow or recommend an unproven company such as ours until such time as we became more seasoned and viable. Generally, the trading market for a company’s securities depends in part on the research and reports that securities or industry analysts publish. We currently have limited research coverage by securities and industry analysts. As a consequence, there may be periods of time when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer with significant research coverage. We cannot give you any assurance that a broader or more active public trading market for our common stock will develop or if developed, will be sustained, or that current trading levels could be sustained or not diminish. In addition, in the event any analysts downgrades our securities, the price of our shares would likely decline. If one or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which could cause the price of our common stock and its trading volume, if any, to decline.

Our common stock may be considered a “penny stock,” and may be subject to additional sale and trading regulations that may make it more difficult to sell.

Our common stock may be considered a “penny stock.” The principal result or effect of being designated a penny stock is that securities broker-dealers participating in sales of our common stock may be subject to the penny stock regulations set forth in Rules 15g-2 through 15g-9 promulgated under the Exchange Act. For example, Rule 15g-2 requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document at least two business days before effecting any transaction in a penny stock for the investor’s account. Moreover, Rule 15g-9 requires broker-dealers in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor. This procedure requires the broker-dealer to (i) obtain from the investor information concerning his or her financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker-dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives. Compliance with these requirements may make it more difficult and time consuming for holders of our common stock to resell their shares to third parties or to otherwise dispose of them in the market or otherwise.

We currently have no available common stock available for new securities issuances, or for the conversion / exercise of outstanding securities, which may restrict us from accessing additional capital through the sale of new securities or the exercise of outstanding convertible securities.

Our Certificate of Incorporation authorizes us to issue up to 150,000,000 shares of common stock, all of which are issued and outstanding as of May 1, 2020. Accordingly, we do not have sufficient authorized shares of common stock for additional issuances. Notwithstanding, the Board currently plans to effect, upon the receipt of necessary shareholder approval, either (i) a reverse stock split or (ii) an increase in authorized shares, in order to authorize additional capital for its future stock issuances, warrant exercises, and conversions of outstanding preferred stock and convertible debentures. Our failure to complete a reverse stock split or an amendment to our certificate of incorporation increasing our authorized shares may further subject us to penalties if we are unable to satisfy conversions of our outstanding convertible debentures, or exercises of our outstanding warrants and options, which may harm our financial position and business prospects.

If our management team is not effective or if we fail to attract, hire or retain qualified personnel, we may not be able to design, develop or commercialize our products successfully or manage our business.

While we have been able to secure a chief executive officer, our anticipated growth and expansion may require the addition of new personnel and the development of additional expertise by existing management. There is intense competition for qualified personnel in such areas. Accordingly, there can be no assurances that we would be able to attract and retain the qualified personnel necessary for the successful development of our business.
