PROSPECTUS SUMMARY

The following summary highlights selected information from this prospectus and does not contain all of the information that you should consider before investing in our common stock. This prospectus contains information regarding our businesses and detailed financial information. You should carefully read this entire prospectus, including the historical financial statements and related notes, before making an investment decision.

In this prospectus, “Opexa Therapeutics, Inc.,” the “company,” “we,” “us” or “our” refer to Opexa Therapeutics, Inc., a Texas corporation, and its subsidiaries, except where otherwise indicated or required by context.

Our Business

We are a biopharmaceutical company developing autologous (using one’s own cells) cellular therapies to treat several major illnesses, including multiple sclerosis (MS), rheumatoid arthritis (RA), and diabetes. These therapies are based on our proprietary T-cell and adult stem cell technologies.

Our lead product, Tovaxin®, is a T-cell based therapeutic vaccine for MS licensed from the Baylor College of Medicine, which offers a unique and personalized approach to treating the disease by inducing an immune response against the autoimmune myelin peptide-reactive T-cells (MRTCs), which are believed to be responsible for the initiation of the disease process.

We are currently conducting a fully enrolled 150 patient Phase IIb clinical trial for Tovaxin. Patients treated in a 10-subject, open-label Phase I/II dose escalation clinical trial with Tovaxin have experienced minimal side effects and the “per protocol” analysis of patients treated with Tovaxin achieved a 90% reduction (p=0.0039) in annualized relapse rate (ARR). Annualized Relapse Rate is a defined neurological episode and is generally the primary clinical efficacy measure for MS therapies. The group treated with the mid dose (30-45 x 106 attenuated T-cells) achieved a 100% reduction in ARR. The Phase IIb trial is being conducted with the mid dose.

In a one-year, 8-subject extension clinical trial of relapsing remitting (RRMS) and secondary progressive (SPMS) subjects, the “per-protocol” analysis of Tovaxin therapy achieved a 92% (p=0.0078) reduction in annualized relapse rate (ARR) in subjects who received two treatment doses of 30-45 x 106 attenuated T-cells eight weeks apart and were monitored for an additional 44 weeks. Subjects in the extension study had previously been treated an average of approximately 5 years earlier at Baylor College of Medicine under the direction of the Tovaxin inventor Jingwu Zhang, M.D., Ph.D with an early version of the T-cell vaccine.

Some patients in the open label Phase I/II studies also appear to experience an improvement of their Kurtzke Expanded Disability Status Scale (EDSS), a scoring method used to measure the disability of MS patients. Improvements in EDSS are not frequently observed in patients following treatment with other currently licensed therapies. Although the data from our Phase I/II trials appears to be promising, the Phase IIb trial is being conducted to confirm these results.

We also hold exclusive worldwide license for the intellectual property rights and research results of an autologous T-cell vaccine for RA from the Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences of the People’s Republic of China.

Our RA T-cell vaccination (TCV) technology is conceptually similar to Tovaxin. RA is an autoimmune T-cell-mediated disease in which pathogenic T-cells trigger an inflammatory autoimmune response of the synovial joints of the wrists, shoulders, knees, ankles and feet which causes pain, stiffness, and swelling around the joints and erosion into cartilage and bone. The RA TCV technology allows the isolation of these pathogenic T-cells from synovial fluid drawn from a patient. These T-cells will be grown to therapeutic levels and attenuated by gamma irradiation in our laboratory. The attenuated T-cells will be injected subcutaneously into patients

thereby inducing an immune response directed at the pathogenic T-cells in the patient’s body. This immune response regulates the level of pathogenic T-cells and potentially allows the reduction of joint swelling in RA patients. Human trials that have been conducted in China show minimal side-effects and promising efficacy measured as a reduction of joint swelling following the T-cell vaccination.

We also have an exclusive license from the University of Chicago, through its prime contractor relationship with Argonne National Laboratory, to a stem cell technology in which adult multipotent stem cells are derived from monocytes (white blood cells) obtained from the patient’s own blood. We are initially pursuing indications in diabetes mellitus with our stem cell therapy and are conducting preclinical animal studies.

Our stem cell technology isolates novel multipotent stem cells derived from peripheral blood monocytes. In vitro experiments with monocyte-derived stem cells (MDSC) have shown their capacity to differentiate into a wide variety of cell types including pancreatic b cells. We have demonstrated that these pancreatic islets clusters derived from MDSCs are composed of three pancreatic cells types (a, b and d). These islet clusters are responsive to glucose and mimic the normal pulsatile pattern observed in human islets. The importance of these stem cells is the ability to easily isolate them from an individual’s circulating monocytes, expand them and administer them back into the same patient. This autologous approach provides a method to overcome any rejection issues and the need for immunosuppressant drugs, which are often associated with current islet cell transplantations. This technology may lead to the formation of an unlimited source of pancreatic islet cells suitable for an autologous cell therapy for the treatment of diabetes mellitus.

RISK FACTORS

The shares offered hereby have not been approved or disapproved by the Security and Exchange Commission or the securities regulatory authority of any state, nor has any such regulatory body reviewed this prospectus for accuracy or completeness. The shares offered hereby are speculative, involve an unusually high degree of risk and should only be purchased by those who can afford to lose their entire investment. Therefore, prospective investors should carefully consider the following risk factors before purchasing the shares offered hereby.

Risks Related to Our Business

The following factors affect our business and the industry in which we operate. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known or which we currently consider immaterial may also have an adverse effect on our business. If any of the matters discussed in the following risk factors were to occur, our business, financial condition, results of operations, cash flows, or prospects could be materially adversely affected.

Our business is at an early stage of development.

Our business is at an early stage of development. We do not have any products in late-stage clinical trials or on the market. We are still in the early stages of identifying and conducting research on potential products. Only one of our products has progressed to the stage of being studied in human clinical trials in the United States (U.S.). Our potential products will require regulatory approval prior to marketing in the United States and other countries. Obtaining such approval will require significant research and development and preclinical and clinical testing. We may not be able to develop any products, to obtain regulatory approvals, to enter clinical trials for any of our product candidates, or to commercialize any products. Our product candidates may prove to have undesirable and unintended side effects or other characteristics adversely affecting their safety, efficacy or cost-effectiveness that could prevent or limit their use. Any product using any of our technology may fail to provide the intended therapeutic benefits, or achieve therapeutic benefits equal to or better than the standard of treatment at the time of testing or production.

We have a history of operating losses and do not expect to be profitable in the near future.

We have not generated any profits since our entry into the biotechnology business, have no source of revenues, and have incurred significant operating losses. We expect to incur additional operating losses for the foreseeable future and, as we increase our research and development activities, we expect our operating losses to increase significantly. We do not have any sources of revenues and may not have any in the foreseeable future.

We will need additional capital to conduct our operations and develop our products and our ability to obtain the necessary funding is uncertain.

We need to obtain significant additional capital resources from sources including equity and/or debt financings, license arrangements, grants and/or collaborative research arrangements in order to develop products and continue our business. As of September 30, 2007, we had cash, cash equivalents and marketable securities of approximately $5.8 million. Our current burn rate is approximately $1 million per month excluding capital expenditures. We will need to raise additional capital to fund our working capital needs beyond first quarter 2008. We must rely upon third-party debt or equity funding and we can provide no assurance that we will be successful in any funding effort. The failure to raise such funds will necessitate the curtailment or ceasing of operations and impact the completion of the clinical trials.

The timing and degree of any future capital requirements will depend on many factors, including:

 

   

the accuracy of the assumptions underlying our estimates for capital needs in 2008 and beyond;

 

   

scientific progress in our research and development programs;

 

5


Table of Contents
Index to Financial Statements
   

the magnitude and scope of our research and development programs;

 

   

our ability to establish, enforce and maintain strategic arrangements for research, development, clinical testing, manufacturing and marketing;

 

   

our progress with preclinical development and clinical trials;

 

   

the time and costs involved in obtaining regulatory approvals;

 

   

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; and

 

   

the number and type of product candidates that we pursue.

We do not have any committed sources of capital, although we have issued and outstanding warrants that, if exercised, would result in an equity capital raising transaction. Additional financing through strategic collaborations, public or private equity financings, capital lease transactions or other financing sources may not be available on acceptable terms, or at all. Additional equity financings could result in significant dilution to our stockholders. Further, if additional funds are obtained through arrangements with collaborative partners, these arrangements may require us to relinquish rights to some of our technologies, product candidates or products that we would otherwise seek to develop and commercialize ourselves. If sufficient capital is not available, we may be required to delay, reduce the scope of or eliminate one or more of our programs, any of which could have a material adverse effect on our financial condition or business prospects.

We have a “going-concern qualification” in our certifying accountant’s financial statement report, which may make capital raising more difficult and may require us to scale back or cease operations.

The report of our auditors includes a going concern qualification which indicates an absence of obvious or reasonably assured sources of future funding that will be required by us to maintain ongoing operations. To date we have successfully funded Opexa by attracting additional issues of equity. We believe that our ongoing efforts will continue to successfully fund operations until positive cash flow is attained. However, there is no guarantee that our efforts will be able to attract additional necessary equity and/or debt investors. If we are unable to obtain this additional funding, we may not be able to continue operations. To date we have been able to obtain funding and meet our obligations in a reasonably timely manner. However, if in the future we are unsuccessful in attracting new sources of funding then we will be unable to continue in business.

Clinical trials are subject to extensive regulatory requirements, very expensive, time-consuming and difficult to design and implement. Our products may fail to achieve necessary safety and efficacy endpoints during clinical trials.

Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous Food and Drug Administration (FDA) requirements, and must otherwise comply with federal, state and local requirements and policies of the medical institutions where they are conducted. The clinical trial process is also time-consuming. We estimate that clinical trials of our product candidates will take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. The commencement and completion of clinical trials may be delayed by several factors, including:

 

   

FDA or Institutional Review Board (IRB) objection to proposed protocols;

 

   

discussions or disagreement with FDA over the adequacy of trial design to potentially demonstrate effectiveness, and subsequent design modifications;

 

   

unforeseen safety issues;

 

   

determination of dosing issues and related adjustments;

 

6


Table of Contents
Index to Financial Statements
   

lack of effectiveness during clinical trials;

 

   

slower than expected rates of patient recruitment;

 

   

product quality problems (e.g., sterility or purity)

 

   

challenges to patient monitoring and data collection during or after treatment (for example, patients’ failure to return for follow-up visits); and

 

   

failure of medical investigators to follow our clinical protocols.

In addition we or the FDA (based on its authority over clinical studies) may delay a proposed investigation or suspend clinical trials in progress at any time if it appears that the study may pose significant risks to the study participants or other serious deficiencies are identified.

We are dependent upon our management team and a small number of employees.

Our business strategy is dependent upon the skills and knowledge of our management team. We believe that the special knowledge of these individuals gives us a competitive advantage. If any critical employee leaves, we may be unable on a timely basis to hire suitable replacements to effectively operate our business. We also operate with a very small number of employees and thus have little or no backup capability for their activities. The loss of the services of any member of our management team or the loss of a number of other employees could have a material adverse effect on our business.

We are dependent on contract research organizations and other contractors for clinical testing and for certain research and development activities, thus the timing and adequacy of our clinical trials and such research activities are, to a certain extent, beyond our control.

The nature of clinical trials and our business strategy requires us to rely on contract research organizations, independent clinical investigators and other third party service providers to assist us with clinical testing and certain research and development activities. For example, our current Phase IIb clinical study of Tovaxin for MS being managed by the contract research organization PharmaNet, LLC. As a result, our success is dependent upon the success of these outside parties in performing their responsibilities. Although we believe our contractors are economically motivated to perform on their contractual obligations, we cannot directly control the adequacy and timeliness of the resources and expertise applied to these activities by our contractors. If our contractors do not perform their activities in an adequate or timely manner, the development and commercialization of our drug candidates could be delayed.

If we fail to meet our obligations under our license agreements, we may lose our rights to key technologies on which our business depends.

Our business depends on three licenses from third parties. These third party license agreements impose obligations on us, such as payment obligations and obligations to diligently pursue development of commercial products under the licensed patents. If a licensor believes that we have failed to meet our obligations under a license agreement, the licensor could seek to limit or terminate our license rights, which could lead to costly and time-consuming litigation and, potentially, a loss of the licensed rights. During the period of any such litigation, our ability to carry out the development and commercialization of potential products could be significantly and negatively affected. If our license rights were restricted or ultimately lost, our ability to continue our business based on the affected technology platform could be severely adversely affected.

Our current research and manufacturing facility is not large enough to manufacture future stem cell and T-cell therapies.

We conduct our research and development in a 10,200 square foot facility in The Woodlands, Texas, which includes an approximately 800 square foot suite of three rooms for the manufacture of stem cell and T-cell

Table of Contents
Index to Financial Statements

therapies through Phase III trials. Our current facility is not large enough to conduct commercial-scale manufacturing operations. We will need to expand further our manufacturing staff and facility, obtain a new facility or contract with corporate collaborators or other third parties to assist with future drug production.

In the event that we decide to establish a commercial-scale manufacturing facility, we will require substantial additional funds and will be required to hire and train significant numbers of employees and comply with applicable regulations, which are extensive. We do not have funds available for building a manufacturing facility, and we may not be able to build a manufacturing facility that both meets regulatory requirements and is sufficient for our commercial-scale manufacturing.

We may arrange with third parties for the manufacture of our future products. However, our third-party sourcing strategy may not result in a cost-effective means for manufacturing our future products. If we employ third-party manufacturers, we will not control many aspects of the manufacturing process, including compliance by these third parties with the FDA’s current Good Manufacturing Practices and other regulatory requirements. We further may not be able to obtain adequate supplies from third-party manufacturers in a timely fashion for development or commercialization purposes, and commercial quantities of products may not be available from contract manufacturers at acceptable costs.

Patents obtained by other persons may result in infringement claims against us that are costly to defend and which may limit our ability to use the disputed technologies and prevent us from pursuing research and development or commercialization of potential products.

A number of pharmaceutical, biotechnology and other companies, universities and research institutions have filed patent applications or have been issued patents relating to cell therapy, stem cells, T-cells, and other technologies potentially relevant to or required by our expected products. We cannot predict which, if any, of such applications will issue as patents or the claims that might be allowed. We are aware that a number of companies have filed applications relating to stem cells. We are also aware of a number of patent applications and patents claiming use of stem cells and other modified cells to treat disease, disorder or injury.

If third party patents or patent applications contain claims infringed by either our licensed technology or other technology required to make and use our potential products and such claims are ultimately determined to be valid, there can be no assurance that we would be able to obtain licenses to these patents at a reasonable cost, if at all, or be able to develop or obtain alternative technology. If we are unable to obtain such licenses at a reasonable cost, we may not be able to develop some products commercially. There can be no assurance that we will not be obliged to defend ourselves in court against allegations of infringement of third party patents. Patent litigation is very expensive and could consume substantial resources and create significant uncertainties. An adverse outcome in such a suit could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties, or require us to cease using such technology.

If we are unable to obtain future patents and other proprietary rights our operations will be significantly harmed.

Our ability to compete effectively is dependent in part upon obtaining patent protection relating to our technologies. The patent positions of pharmaceutical and biotechnology companies, including ours, are uncertain and involve complex and evolving legal and factual questions. The coverage sought in a patent application can be denied or significantly reduced before or after the patent is issued. Consequently, we do not know whether the patent applications for our technology will result in the issuance of patents, or if any future patents will provide significant protection or commercial advantage or will be circumvented by others. Since patent applications are secret until the applications are published (usually eighteen months after the earliest effective filing date), and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that the inventors of our licensed patents were the first to make the inventions covered by the patent applications or that the licensed patent applications were the first to be filed for such inventions. There can

Index to Financial Statements

be no assurance that patents will issue from the patent applications or, if issued, that such patents will be of commercial benefit to us, afford us adequate protection from competing products, or not be challenged or declared invalid.

Our competition includes fully integrated biopharmaceutical and pharmaceutical companies that have significant advantages over us.

The markets for therapeutic stem cell products, multiple sclerosis products, and rheumatoid arthritis products are highly competitive. We expect that our most significant competitors are fully integrated pharmaceutical companies and more established biotechnology companies. These companies are developing stem cell-based products and they have significantly greater capital resources and expertise in research and development, manufacturing, testing, obtaining regulatory approvals, and marketing than we currently do. Many of these potential competitors are further along in the process of product development and also operate large, company-funded research and development programs. As a result, our competitors may develop more competitive or affordable products, or achieve earlier patent protection or product commercialization than we are able to achieve. Competitive products may render any products or product candidates that we develop obsolete.

Restrictive and extensive government regulation could slow or hinder our production of a cellular product.

The research and development of stem cell therapies is subject to and restricted by extensive regulation by governmental authorities in the United States and other countries. The process of obtaining FDA and other necessary regulatory approvals is lengthy, expensive and uncertain. We may fail to obtain the necessary approvals to continue our research and development, which would hinder our ability to manufacture or market any future product.

To be successful, our product candidates must be accepted by the health care community, which can be very slow to adopt or unreceptive to new technologies and products.

Our product candidates, if approved for marketing, may not achieve market acceptance since hospitals, physicians, patients or the medical community in general may decide to not accept and utilize these products. The product candidates that we are attempting to develop represent substantial departures from established treatment methods and will compete with a number of more conventional drugs and therapies manufactured and marketed by major pharmaceutical companies. The degree of market acceptance of any of our developed products will depend on a number of factors, including:

 

   

our establishment and demonstration to the medical community of the clinical efficacy and safety of our product candidates;

 

   

our ability to create products that are superior to alternatives currently on the market;

 

   

our ability to establish in the medical community the potential advantage of our treatments over alternative treatment methods; and

 

   

reimbursement policies of government and third-party payers.

If the health care community does not accept our products for any of the foregoing reasons, or for any other reason, our business would be materially harmed.

Risks Related to Our Common Stock

There is currently a limited market for our common stock, and any trading market that exists in our common stock may be highly illiquid and may not reflect the underlying value of the Company’s net assets or business prospects.

Although our common stock is traded on the NASDAQ Capital Market, there is currently a limited market for our common stock and there can be no assurance that an improved market will ever develop. Investors are cautioned not to rely on the possibility that an active trading market may develop.

As our share price is volatile, we may be or become the target of securities litigation, which is costly and time-consuming to defend.

In the past, following periods of market volatility in the price of a company’s securities or the reporting of unfavorable news, security holders have often instituted class action litigation. If the market value of our common stock experiences adverse fluctuations and we become involved in this type of litigation, regardless of the outcome, we could incur substantial legal costs and our management’s attention could be diverted from the operation of our business, causing our business to suffer.

Our “blank check” preferred stock could be issued to prevent a business combination not desired by management or our current majority shareholders.

Our articles of incorporation authorize the issuance of “blank check” preferred stock with such designations, rights and preferences as may be determined by our board of directors without shareholder approval. Our preferred stock could be utilized as a method of discouraging, delaying, or preventing a change in our control and as a method of preventing shareholders from receiving a premium for their shares in connection with a change of control.

Future sales of our common stock in the public market could lower our stock price.

We may sell additional shares of common stock in subsequent public or private offerings. We may also issue additional shares of common stock to finance future acquisitions. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock.

We presently do not intend to pay cash dividends on our common stock.

We currently anticipate that no cash dividends will be paid on the common stock in the foreseeable future. While our dividend policy will be based on the operating results and capital needs of the business, it is anticipated that all earnings, if any, will be retained to finance the future expansion of the our business.

There are a large number of shares underlying our warrants that may be available for future sale. Substantial sales of our common stock by our current holders or us could cause our stock price to decline and issuances by us may dilute your ownership interest in our company.

We are unable to predict whether significant amounts of our common stock will be sold by our current holders after this offering. Any sales of substantial amounts of our common stock in the public market by our current holders or us, or the perception that these sales might occur, such as might arise from exercise of outstanding warrants, could lower the market price of our common stock. Further, if we issue additional equity securities to raise additional capital, your ownership interest in our company may be diluted and the value of your investment may be reduced. Please read “Description of Securities” for information about the number of shares that will be outstanding and that could be acquired through warrant exercise after this offering.

There is currently no market for our Series E warrants and we do not expect a liquid market for the Series E warrants to develop.

There is currently no market for our Series E warrants; and, although we expect to have the Series E warrants listed on the NASDAQ Capital Market, we do not expect a significant liquid market for the Series E warrants to develop. To the extent a market for the Series E warrants does develop, the price for the Series E warrants will depend, in large part, on the price of our common stock.

If we do not maintain an effective registration statement or comply with applicable state securities laws, you may not be able to exercise the warrants.

In order for you to be able to exercise the warrants offered hereby, the underlying shares must be covered by an effective registration statement and qualify for an exemption under the securities laws of the state in which you live. We cannot assure you that we will continue to maintain a current registration statement relating to the offer and sale of the warrants and the common stock underlying these warrants, or that an exemption from registration or qualification will be available throughout their term. This may have an adverse effect on the demand for the warrants and the prices that can be obtained from reselling them.

The warrants may be redeemed on short notice. This may have an adverse impact on their price.

We may redeem the warrants for $0.01 per warrant once a share of common stock has traded at $             (200% of the share public offering price) for 20 consecutive trading days. If we give notice of redemption, you will be forced to sell or exercise your warrants or accept the redemption price. The notice of redemption could come at a time when it is not advisable or possible for you to exercise the warrants. As a result, you would be unable to benefit from owning the warrants being redeemed.

FORWARD LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933. These statements relate to future events and/or future financial performance and involve known and unknown risks, uncertainties and other factors that may cause the actual results, levels of our activity, performance or achievements or the industry in which we operate to be materially different from any future results, levels of activity, performance or achievements expressed or implied by the forward-looking statements. These risks and other factors include those listed under “Risk Factors” and those described elsewhere in this prospectus.

In some cases, you can identify forward-looking statements by our use of terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” or the negative of these terms or other comparable terminology. These statements are only predictions. Actual events or results may differ materially. In evaluating these statements, you should specifically consider various factors, including the risks outlined under “Risk Factors.” These factors may cause our actual results to differ materially from any forward-looking statement.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, it cannot guarantee future results, levels of activity, performance, or achievements. Moreover, neither the Company nor any other person assumes responsibility for the accuracy and completeness of these forward-looking statements. We do not intend to update any of the forward-looking statements after the date of this prospectus to conform prior statements to actual results.

USE OF PROCEEDS

We expect that we will receive net proceeds of approximately $15.2 million (or $17.5 million if the underwriter exercises its over-allotment option in full) after deducting underwriting discounts and commissions and estimated offering expenses that we will pay, assuming no proceeds from warrants being issued and an assumed offering price of $3.79 for each share and $0.15 for each warrant.

We intend to use the net proceeds of our sales of common stock and the associated warrants in this offering to complete the Tovaxin Phase IIb clinical study, fund the second year open label extension study being offered to patients who complete the Phase IIb study, initiate an extension study of the Phase IIb participants and fund the advancement of our MDSC–Diabetes program into a Phase I clinical study. The proceeds should fund the company through the first quarter of 2009. Pending these uses, the net proceeds will be invested in an interest-bearing money market account with a financial institution.

We do not anticipate that any cash dividends will be paid in the foreseeable future. While our dividend policy will be based on the operating results and capital needs of the business, we anticipate that all earnings, if any, will be retained to finance our future expansion. Therefore, prospective investors who anticipate the need for immediate income by way of cash dividends from their investment should not purchase the shares offered by this prospectus.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read together with the consolidated financial statements and related notes that are included elsewhere in this prospectus. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors”, “Disclosure Regarding Forward-Looking Statements” or in other parts of this prospectus. We undertake no obligation to update any information in our forward-looking statements except as required by law.

Overview

We are a development-stage company and have a limited operating history. Our predecessor company for financial reporting purposes was formed on January 22, 2003 to acquire rights to our adult stem cell technology. In November 2004 we acquired Opexa Pharmaceuticals, Inc. and its MS treatment technology. We are still developing all of our technology, and to date, we have not generated any revenues from our operations. As we continue to execute our operations plan, we expect our development and operating expenses to increase.

Research and development. We have made and expect to continue to make substantial investments in research and development in order to develop and market our technology. Research and development costs consist primarily of general and administrative and operating expenses related to research and development activities. We expense research and development costs as incurred. Acquired research and development that has no alternative future use is expensed when acquired. Property, plant and equipment for research and development that has an alternative future use is capitalized and the related depreciation is expensed as research and development costs. We expect our research and development expense to increase as we continue to invest in the development of our technology.

General and administrative. General and administrative expenses consist primarily of salaries and benefits, stock compensation expenses, office expense, professional services fees, and other corporate overhead costs. We anticipate increases in general and administrative expenses as we continue to develop and prepare for commercialization of our technology.

Results of Operations

Three Months Ended September 30, 2007 Compared with the Three Months Ended September 30, 2006

Net Sales. We recorded no sales for the three months ended September 30, 2007 and 2006.

Research and Development Expenses. Research and development expense was $3,189,256 for the three months ended September 30, 2007, compared to $2,113,878 for the three months ended September 30, 2006. The increase in expenses was primarily due to the costs of the Phase IIb clinical trial for Tovaxin and stock compensation expense recorded in 2007. We have made and expect to continue to make substantial investments in research and development in order to develop and market our technology. We expense research and development costs as incurred. Acquired research and development that has no alternative future use is expensed when acquired. We expect our research and development expense to increase as we continue to invest in the development of our technology.

General and Administrative Expenses. Our general and administrative expense was $842,079 for the three months ended September 30, 2007, as compared to $1,430,507 for the three months ended September 30, 2006. The decrease in expenses is primarily due to a decrease in stock compensation expenses, professional service fees and overhead expenses. We anticipate increases in general and administrative expenses as we continue to develop and prepare for commercialization of our technology.

Interest Expense. Interest expense was $4,731 for the three months ended September 30, 2007, compared to $278 for the three months ended September 30, 2006. The increase in interest expense was primarily due to a loan payable consisting of an equipment line of up to $250,000 with Wells Fargo of which $236,563 was outstanding as of September 30, 2007.

Interest Income. Interest income was $102,292 for the three months ended September 30, 2007 compared to $259,141 for the three months ended September 30, 2006. The decrease was due to the reduction in cash balances that were available for investment in cash equivalent investments.

Net loss. We had a net loss for the three months ended September 30, 2007, of $2,371,780, or $0.35 per share (basic and diluted), compared with a net loss of $919,283, or $0.14 per share (basic and diluted), for the three months ended September 30, 2006. The increase in net loss is primarily due to the costs of the Phase IIb clinical trial for Tovaxin offset by a reduction in stock-based compensation expense and gain on extinguishment of debt.

Nine Months Ended September 30, 2007 Compared with the Nine Months Ended September 30, 2006

Net Sales. We recorded no sales for the nine months ended September 30, 2007 and 2006.

Research and Development Expenses. Research and development expense was $10,148,930 for the nine months ended September 30, 2007, compared to $4,532,240 for the nine months ended September 30, 2006. The increase in expenses was primarily due to the costs of the Phase IIb clinical trial for Tovaxin, research and development in support of pre-clinical diabetes stem cell therapies and stock compensation expense recorded in 2007. We have made and expect to continue to make substantial investments in research and development in order to develop and market our technology. We expense research and development costs as incurred. Acquired research and development that has no alternative future use is expensed when acquired. We expect our research and development expense to increase as we continue to invest in the development of our technology.

General and Administrative Expenses. General and administrative expense was $2,557,609 for the nine months ended September 30, 2007, as compared to $5,676,221 for the nine months ended September 30, 2006. The decrease in expenses is primarily due to a decrease in stock compensation expenses, professional service fees and overhead expenses. We anticipate increases in general and administrative expenses as we continue to develop and prepare for commercialization of our technology.

Interest Expense. Interest expense was $10,875 for the nine months ended September 30, 2007, compared to $891 for the nine months ended September 30, 2006. The increase in interest expense was primarily due to a loan payable consisting of an equipment line of up to $250,000 with Wells Fargo of which $236,563 was outstanding as of September 30, 2007.

Interest Income. Interest income was $423,086 for the nine months ended September 30, 2007 compared to $477,547 for the nine months ended September 30, 2006. The decrease was due to the reduction in cash balances that were available for investment in cash equivalent investments.

Net loss. We had a net loss for the nine months ended September 30, 2007, of $10,835,293, or $1.62 per share (basic and diluted), compared with a net loss of $10,670,331, or $2.16 per share (basic and diluted), for the nine months ended September 30, 2006. The increase in net loss is primarily due to the costs associated with the Phase IIb clinical trial for Tovaxin offset by a reduction in stock-based compensation expense, gain on extinguishment of liability and loss on derivative instruments.

Comparison of Year Ended December 31, 2006 with the Year Ended December 31, 2005

Net Sales. We recorded no sales for the twelve months ended December 31, 2006 and December 31, 2005.

Research and Development Expense. Research and development expense was $7,850,373 for the twelve months ended December 31, 2006, as compared to $5,159,853 the twelve months ended December 31, 2005. The increase in expenses was primarily due to the costs of the Phase I/II and Phase IIb clinical trials for Tovaxin and research and development in support of pre-clinical diabetes stem cell therapies. We have made and expect to continue to make substantial investments in research and development in order to develop and market our technology. We expense research and development costs as incurred. Acquired research and development that has no alternative future use is expensed when acquired. Property, plant and equipment for research and development that has an alternative future use is capitalized and the related depreciation is expensed as research and development costs. We expect our research and development expense to increase as we continue to invest in the development of our technology.

General and Administrative Expenses. Our general and administrative expenses during the twelve months ended December 31, 2006, was $5,461,047 as compared to $6,259,075 for the twelve months ended December 31, 2005. The decrease in expenses is due to a combination of factors including a decrease in stock compensation expenses, professional service fees and overhead expenses in 2006. General and administrative expenses consist primarily of salaries and benefits, stock compensation expense, office expense, professional services fees, and other corporate overhead costs. We anticipate increases in general and administrative expenses as we continue to develop and prepare for commercialization of our technology.

Interest Expense. Interest expense was $984 for the twelve months ended December 31, 2006 compared to $7,323,851 for the twelve months ended December 31, 2005. Interest expense during 2005 was due to notes payable that were outstanding during the second quarter of 2005 which were subsequently converted into equity in June 2005, resulting in acceleration of the amortization of the discount related to the notes.

Interest Income. Interest income was $688,299 for the twelve months ended December 31, 2006 compared to $81,930 for the twelve months ended December 31, 2005. The increase was due to the investment of the cash proceeds from a 2006 equity financing in short term and cash equivalent investments.

Gain (Loss) on Derivative Instruments Liabilities, net. We recognized a gain on derivative instruments of $104,978 for the twelve months ended December 31, 2006 compared to $3,896,841 for the twelve months ended December 31, 2005. The decrease is a result of the net unrealized (non-cash) change in the fair value of our derivative instrument liabilities.

Net Loss. We had net loss for the year ended December 31, 2006, of $12,649,170 or ($2.35) per share (basic and diluted), compared with a net loss of $14,856,724 or ($9.49) per share (basic and diluted), for the twelve months ended December 31, 2005.

Liquidity and Capital Resources

Changes in cash flow. Cash used in operations for the nine month period ended September 30, 2007 was $6,154,074, as compared to $5,899,299 used in operations for the nine months ended September 30, 2006. The increase in cash used in operations is primarily due to an increase in operating expenses offset in part by the maturity of approximately $2.9 million in marketable securities and its reclassification to cash and cash equivalents and by an increase in accrued expenses resulting from the Phase IIb clinical trial. Cash used in investing activities for the nine month period ended September 30, 2007 was $147,782, as compared to $487,567 for the nine months ended September 30, 2006. The decrease was primarily due to a decrease in equipment purchases. Cash provided from financing activities for the nine month period ended September 30, 2007 was $126,241, as compared to $21,153,520 for the nine months ended September 30, 2006. The decrease was due to the proceeds from the April 2006 equity financing.

Table of Contents
Index to Financial Statements

We used approximately $11.0.million of cash for operating activities for the year ended December 31, 2006 compared to approximately $6.2 million for the same period of 2005. The increase in use of cash is primarily due to an increase in research and development expenditures related to the clinical trials for our Tovaxin therapy for MS and the purchase of marketable securities.

Capital expenditures were approximately $0.6 million in 2006 and consisted primarily of laboratory equipment and leasehold improvements related to the construction of manufacturing facilities.

Liquidity. Historically, the Company has financed its operations primarily from the sale of its debt and equity securities. As of September 30, 2007, the Company had cash, cash equivalents and marketable securities of approximately $5.8 million.

Our financing activities generated approximately $21.3 million for the year ended December 31, 2006 as compared to approximately $8.2 million for the same year ended December 31, 2005. In both periods, the cash generated from financing activities resulted from the sale of common stock in equity financings.

Our current burn rate is approximately $1 million per month excluding capital expenditures. Without the proceeds of this offering, we would need to raise additional capital to fund our working capital needs beyond the first quarter of 2008. Currently, we have determined that if we do not raise additional funds, there is a concern about our ability to continue our operations and our independent accountants have added a going concern paragraph to their report on the audit financial statements for the year ended December 31, 2006.

We recently terminated a private offering of equity to accredited investors. We sought to raise up to $20 million in gross proceeds and considered selling either common stock or convertible preferred stock with warrants to purchase common stock. We later determined that a public offering of common stock was more desirable for the company and therefore terminated our private financing effort on October 24, 2007. This offering supersedes the previous private equity offering.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily

apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our most significant judgments and estimates used in preparation of our consolidated financial statements.

Reverse Acquisition. We treated the merger of PharmaFrontiers Corp. into Sportan as a reverse acquisition. Pursuant to the guidance in Appendix B of SEC Accounting Disclosure Rules and Practices Official Text, the “merger of a private operating company into a non-operating public shell corporation with nominal net assets typically results in the owners and management of the private company having actual or effective operating control of the combined company after the transaction, with the shareholders of the former public shell continuing only as passive investors. These transactions are considered by the staff to be capital transactions in substance, rather than business combinations. That is, the transaction is equivalent to the issuance of stock by the private company for the net monetary assets of the shell corporation, accompanied by a recapitalization.” Accordingly, the reverse acquisition has been accounted for as a recapitalization. For accounting purposes, the original PharmaFrontiers Corp. is considered the acquirer in the reverse acquisition. The historical financial statements are those of the original PharmaFrontiers Corp. Earnings per share for periods prior to the merger are restated to reflect the number of equivalent shares received by the acquiring company.

Stock-Based Compensation. On January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (“SFAS 123R”) which establishes accounting for equity instruments exchanged for employee service. We utilize the Black-Scholes option pricing model to estimate the fair value of employee stock based compensation at the date of grant, which requires the input of highly subjective assumptions, including expected volatility and expected life. Further, as required under SFAS 123R, we now estimate forfeitures for options granted, which are not expected to vest. Changes in these inputs and assumptions can materially affect the measure of estimated fair value of our share-based compensation. These assumptions are subjective and generally require significant analysis and judgment to develop. When estimating fair value, some of the assumptions will be based on, or determined from, external data and other assumptions may be derived from our historical experience with stock-based payment arrangements. The appropriate weight to place on historical experience is a matter of judgment, based on relevant facts and circumstances.

We estimated volatility by considering historical stock volatility. As allowed by Staff Accounting Bulletin (SAB) No. 107, Share-Based Payment, we have opted to use the simplified method for estimating expected term equal to the midpoint between the vesting period and the contractual term.

Research and Development. The costs of materials and equipment or facilities that are acquired or constructed for research and development activities and that have alternative future uses are capitalized as tangible assets when acquired or constructed. The cost of such materials consumed in research and development activities and the depreciation of such equipment or facilities used in those activities are research and development costs. However, the costs of materials, equipment, or facilities acquired or constructed for research and development activities that have no alternative future uses are considered research and development costs and are expensed at the time the costs are incurred.

Accounting for Derivative Instruments. Statement of Financial Accounting Standard (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended, requires all derivatives to be recorded on the balance sheet at fair value. These derivatives are separately valued and accounted for on our balance sheet. Fair values for securities traded in the open market and derivatives are based on quoted market prices. Where market prices are not readily available, fair values are determined using market based pricing models incorporating readily observable market data and requiring judgment and estimates.

The pricing model we use for determining fair values of our derivatives is the Black Scholes Pricing Model. Valuations derived from this model are subject to ongoing internal and external verification and review. The model uses market-sourced inputs such as interest rates, exchange rates and stock price volatilities. Selection of these inputs involves management’s judgment and may impact net income.

In September 2000, the Emerging Issues Task Force (“EITF”) issued EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in, a Company’s Own Stock,” (“EITF 00-19”) which requires freestanding contracts that are settled in a company’s own stock, including common stock warrants, to be designated as an equity instrument, asset or a liability. Under the provisions of EITF 00-19, a contract designated as an asset or a liability must be carried at fair value on a company’s balance sheet, with any changes in fair value recorded in the company’s results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required. In accordance with EITF 00-19, in June 2006, we determined that certain outstanding warrants to purchase our common stock should be separately accounted for as liabilities. We had not classified these derivative liabilities as such in our historical financial statements. In order to reflect these changes, we restated our financial statements for the year ended December 31, 2005 to record the fair value of these warrants on our balance sheet and record unrealized changes in the values of these derivatives in our consolidated statement of operations as “Gain (loss) on derivative liabilities.”

We have evaluated the provisions of the registration rights agreement that require us to pay registration delay payments in combination with the financial instrument and concluded that the combined instrument meets the definition of a derivative under SFAS 133.

In December 2006, the FASB issued FASB Staff Position No. EITF 00-19-2, Accounting for Registration Payment Arrangements (EITF 00-19-2). EITF 00-19-2 addresses an issuer’s accounting for registration payment arrangements. It specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. The guidance in EITF 00-19-2 amends FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and FASB Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, to include scope exceptions for registration payment arrangements. EITF 00-19-2 also requires additional disclosure regarding the nature of any registration payment arrangements, alternative settlement methods, the maximum potential amount of consideration and the current carrying amount of the liability, if any. This EITF is effective immediately for registration payment arrangements and the financial instruments subject to those arrangements that are entered into or modified subsequent to the date of issue of this EITF. For registration payment arrangements and financial instruments subject to those arrangements that were entered into prior to the issuance of this EITF, this is effective for financial statements issued for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. The impact of implementing EITF 00-19-2 in the fiscal year 2007 resulted in a cumulative effect of a change in accounting principle with a credit to beginning retained earnings of $6,656,677 and a reversal of the same amount to the derivative liability account.

OUR BUSINESS

Overview

We are a biopharmaceutical company developing autologous cellular therapies to treat several major illnesses, including multiple sclerosis (MS), rheumatoid arthritis (RA) and diabetes. These therapies are based on our proprietary T-cell and adult stem cell technologies.

T-Cell Therapy

We have the exclusive worldwide license from Baylor College of Medicine to an individualized T-cell therapeutic vaccine, Tovaxin, which is in United States (U.S.) FDA Phase IIb human clinical trials to evaluate its safety and effectiveness in treating MS.

MS is the result of a person’s own T-cells attacking the myelin sheath that coats the nerve cells of the central nervous system (CNS). Tovaxin consists of attenuated patient-specific myelin reactive T-cells (MRTCs) against peptides from one or more of the primary proteins on the surface of the myelin sheath (myelin basic protein (MBP), proteolipid protein (PLP) and myelin oligodendrocyte glycoprotein (MOG)). Patient-specific MRTCs are expanded in culture with specific peptides identified by our proprietary test of the patient’s peripheral blood, the cells are attenuated by gamma irradiation, and then returned to the patient as a subcutaneous injection. Although further testing is necessary, results from our initial human trials appear to indicate that these attenuated T-cells cause an immune response directed at the autoreactive T-cells in the patient’s body, stimulating a reduction in the level of harmful T-cells.

We believe that our initial human trials suggest that Tovaxin safely induces the depletion and regulation of MRTCs, possibly stabilizing the disease, reducing the annualized relapse rate, and potentially improving the disability scores of patients. Patients treated in a 10-subject, open-label Phase I/II dose escalation clinical trial with Tovaxin have experienced minimal side effects and the “per protocol” analysis of patients treated with Tovaxin achieved a 90% reduction (p=0.0039) in annualized relapse rate (ARR). The group treated with the mid dose (30-45 x 106 attenuated T-cells) achieved a 100% reduction in ARR. The Phase IIb trial is being conducted with the mid dose.

In a one-year, 8-subject extension clinical trial of relapsing remitting (RRMS) and secondary progressive (SPMS) subjects, the “per-protocol” analysis of Tovaxin therapy achieved a 92% (p=0.0078) reduction in annualized relapse rate (ARR) in subjects who received two treatment doses of 30-45 x 106 attenuated T-cells eight weeks apart and were monitored for an additional 44 weeks. Subjects in the extension study had previously been treated an average of approximately 5 years earlier at Baylor College of Medicine under the direction of the inventor of Tovaxin Jingwu Zhang, M.D., Ph.D with an early version of the T-cell vaccine.

In November 2006, we enrolled the first patient in a double blind, placebo controlled, 150 patient Phase IIb clinical trial. We completed enrollment of all 150 patients in May 2007.

Our Rheumatoid Arthritis (RA) T-cell vaccination (TCV) technology is conceptually similar to Tovaxin. RA is an autoimmune T-cell-mediated disease in which pathogenic T-cells trigger an inflammatory autoimmune response of the synovial joints of the wrists, shoulders, knees, ankles and feet which causes pain, stiffness, and swelling around the joints and erosion into cartilage and bone. Our RA TCV technology allows the isolation of these pathogenic T-cells from synovial fluid drawn from a patient. We will expand and attenuate these T-cells in our laboratory. The attenuated T-cells will be injected subcutaneously into patients with the goal of inducing an immune response directed at the Pathogenic T-cells in the patient’s body. We believe this immune response could reduce the level of pathogenic T-cells and potentially allow the reduction of joint swelling in RA patients.

Stem Cell Therapy

We have developed a proprietary adult stem cell technology to produce novel monocyte-derived stem cells (MDSC) from blood. These MDSC can be derived from a patient’s monocytes, expanded ex vivo, and then administered to the same patient. We believe that because this is an autologous therapy, there should be no rejection issues as self-derived MDSC pose no immunological problems. Normally, allogenic cells are deleted by host immune responses and require the use of anti-rejection drugs.

Our novel multi-potent stem cell is derived from peripheral blood monocytes which when cultured under defined conditions are able to further differentiate into several cellular lineages. Molecular biology and immunohistochemical studies have shown that these MDSCs have specific markers that distinguish them from other stem cells. In addition these studies have also shown a time-dependence for the expression of these specific gene products during the growth and differentiation of MDSCs. In vitro experiments with MDSCs have shown their capacity to differentiate towards hematopoietic, epithelial, endothelial, endocrine and neuronal cells. Our main focus is the further development of this monocyte-derived stem cell (MDCS) technology as a novel platform for the in vitro generation of highly specialized cells for potential application in autologous cell therapy for patients with diseases such diabetes mellitus and cardiovascular disease.

Other Opportunities

We intend to conduct basic research to determine the potential use of stem cells and differentiated cells in other indications, such as macular degeneration, stroke, myocardial infarction, wound healing and Parkinson’s disease. We intend to partner or sublicense some of these indications if they are not pursued for internal development. For those indications where we believe we can participate commercially, we desire to partner in key commercial markets outside of the U.S.

The Company’s Products and Services

Our T-cell Platform

Multiple Sclerosis—Background

In the U.S., approximately 400,000 people suffer from MS, a chronic progressive autoimmune disease of the central nervous system (CNS) that is caused by myelin autoreactive T-cells progressively eroding the myelin that surrounds and insulates nerve fibers of the brain and spinal cord resulting in varying amounts of disability. Globally, there are approximately 2.5 million MS patients representing a drug market believed to be approximately $5 billion in 2005. The US markets accounted for slightly more than 50 percent of global MS sales in 2005, approximately $2.5 billion. MS remains a challenging autoimmune disease to treat because the pathophysiologic mechanisms are diverse, and the chronic, unpredictable course of the disease makes it difficult to determine whether the favorable effects of short-term treatment will be sustained. Therapies that are easy to use and can safely prevent or stop the progression of disease represent the greatest unmet need in MS.

In recent years, the understanding of MS pathogenesis has evolved to comprise an initial, T-cell-mediated inflammatory activity followed by selective demyelination (erosion of the myelin coating of the nerve fibers) and then neurodegeneration. The discovery of disease-relevant immune responses has accelerated the development of targeted therapeutic products for the treatment of the early stages of MS.

Some subjects, who have the appropriate genetic background, have increased susceptibility for the in vivo activation and clonal expansion of myelin autoreactive T-cells. These myelin autoreactive T-cells may remain dormant, but at some point they are activated in the periphery, possibly by molecular mimicry (i.e., recognition of epitopes that are common to autoantigens and microbial antigens as exogenous triggers), thus enabling them to cross the blood-brain barrier (BBB) and infiltrate the healthy tissue of the brain and spinal cord. The cascade of pathogenic events leads to demyelination of axons, which causes nerve impulse transmissions to diffuse into the tissue.

Current Therapy for Multiple Sclerosis

Current MS disease modifying drugs on the market are mostly palliative and generally work through a mechanism of immunomodulation or immunosuppression. These therapies for MS are dominated by three forms of interferon that require frequent subcutaneous or intramuscular injections (Avonex, Betaseron and Rebif). Copaxone is an immunomodulator composed of a random copolymer of amino acids that is administered daily. Novantrone (mitoxanthrone) is an immunosuppressive drug that can only be given four times per year with a life time limit of 8 to 12 doses. All of the current therapies only slow the progression of MS and they have significant patient compliance challenges because of the dosing schedule, limited decrease in relapse rate, side effects profile (e.g., the interferon formulations produce severe flu-like symptoms, injection site reactions, infection and neutralizing antibodies (ranging from 5% to 45%) are developed that limits the efficacy of treatment; Copaxone causes significant injection site reactions; while Novantrone causes infections, bone marrow suppression, nausea, hair thinning, bladder infections, and mouth sores). These drugs must be administered daily to weekly. Tysabri®, a selective adhesion molecule inhibitor (an alpha 4 integrin antagonist), represents another class of MS drugs that works by preventing immune system cells (all leukocytes carrying the alpha 4 integrin glycoprotein on their surface) from crossing the BBB and move into the CNS. Tysabri® requires a once per month infusion and has been reintroduced to the market after being originally withdrawn in 2005 based on safety concerns over several patient deaths due to virally mediated brain inflammation—a condition called progressive multifocal leukoencephalopathy (PML).

Tovaxin for Multiple Sclerosis

We believe that Tovaxin works selectively on the myelin autoreactive T-cells by harnessing the body’s natural immune defense system and feedback mechanisms to deplete these T-cells and induce favorable immune regulatory responses by rebalancing the immune system. Tovaxin is manufactured by taking the MRTCs from the blood, expanding them to a therapeutic dose ex-vivo, and attenuating them with gamma irradiation to prevent DNA replication. These attenuated MRTCs are then injected subcutaneously into the body in large quantities. The body recognizes specific T-cell receptor molecules of these MRTCs as foreign and mounts an immune response reaction against them, not only destroying the injected attenuated MRTCs, but also the circulating, myelin autoreactive T-cells carrying the peptide-specific T-cell receptor molecules. In addition, T-cell activation molecules on the surface of the activated MRTCs used as vaccine induce favorable immune regulatory responses, which promote anti-inflammatory responses. Because the therapy uses an individual’s own cells, the only directly identifiable side effect, observed thus far, is injection site reaction in a small percentage of the patients. These reactions clear within 24 hours.

We believe that this technology platform may have applications in other T-cell mediated diseases such as Crohn’s disease, psoriasis, RA and Type 1diabetes.

Tovaxin Intellectual Property

The technology is based on discoveries made by Dr. Jingwu Zang of Baylor College of Medicine in Houston. We have an exclusive, worldwide license from the Baylor College of Medicine to develop and commercialize three technology areas for MS, namely T-cell vaccination, peptides, and diagnostics. Under the License Agreement with the Baylor College of Medicine, we have rights to a total of 11 patents (2 U.S. and 9 foreign) and 80 patent applications (6 U.S. and 74 foreign).

Tovaxin Manufacturing

We manufacture our TCV therapy in our own Good Manufacturing Practice (“GMP”) facility. The TCV technology producing Tovaxin is similar to that of traditional microbial vaccine technology, where the pathogen (or the attenuated derivative) is used to derive the protective antigens necessary to induce protective immune responses. In preparing the Tovaxin for a patient, the myelin autoreactive T-cells causing the disease are taken

from the blood, specifically identified, and expanded ex vivo by incubating these T-cells with selected peptides of MBP, PLP, and MOG in the presence of antigen-presenting cells and growth factors. Myelin-peptide reactive T-cells are grown to therapeutic levels and cryopreserved. Prior to use, the MRTCs are expanded, formulated, and attenuated (by irradiation) to render them incompetent to replicate but viable for therapy. These attenuated T-cells are administered in a defined schedule of subcutaneous injections. We have shown that a single draw of a 500 ml bag of blood is sufficient to provide a full year’s therapeutic regimen of Tovaxin.

Clinical Development of Tovaxin

Tovaxin is currently in a Phase IIb clinical trial. Patients treated in our Phase I/II open-label studies with Tovaxin have experienced minimal side effects, an approximate 90% average reduction in annualized relapse rate and improvements in EDSS disability scores.

Tovaxin Phase IIb Clinical Trial

The Phase IIb trial, entitled “A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Subcutaneous Tovaxin in Subjects with Clinically Isolated Syndrome or Relapsing Remitting Multiple Sclerosis”, is a multi-site double-blind, randomized, placebo-controlled 150 (100 treated, 50 placebo) patient trial. The trial is being conducted at 33 sites in the U.S. The primary endpoint will be brain lesion evaluation (the total number of gadolinium-enhancing lesions) via MRI with a secondary endpoint being annual relapse rate. This trial is designed to demonstrate the safety and efficacy of Tovaxin. We completed enrollment in May 2007 and expect top-line results in the fourth quarter of 2008.

Our Adult Stem Cell Platform

Stem Cells—Background

Stem cells are undifferentiated primary cells that have the potential to become any tissue or organ of the body. They hold therapeutic promise for the development of effective treatments and possibly cure for various diseases. The current stem cell research efforts have been divided between embryonic and tissue specific adult stem cells as potential therapeutic progenitor cells. Recent experiments with embryonic stem (ES) cells have demonstrated that these highly proliferative, pluripotent cells can differentiate into pancreatic-like b-cells. The major problem with ES cells is their pluripotency and risk that these cells, once transplanted, could form tumors. Given that, adult tissue specific stem cells have become attractive as a potential cell therapeutic. Adult tissue specific stem cells have advantages over ES cells; first, these cells can be isolated from a more manageable source such as bone marrow or other tissues; second, they proliferate in a controlled fashion and without the likelihood of tumorogenicity, and third, they can be used in an autologous setting and avoid the potential for rejection which exists for allogenic use of stem cells.

Hematopoietic stem cells (HSC’s), present in the bone marrow and precursors to all blood cells, are currently the only type of stem cells commonly used for therapy. Doctors have been transferring HSC’s in bone marrow transplants for more than 40 years. Advanced techniques for collecting or “harvesting” HSC’s are now used to treat leukemia, lymphoma and several inherited blood disorders.

The clinical potential of stem cells has also been demonstrated in the treatment of other human diseases, including diabetes and advanced kidney cancer. However, these new therapies have been offered only to a very limited number of patients using adult stem cells.

Stem cell therapies have technical, ethical and legal hurdles to overcome before they will be able to be used to possibly affect tissue and organ repair. A significant hurdle to most uses of stem cells is that scientists do not yet fully understand the signals that turn specific genes on and off to influence the differentiation of the stem cell. Therefore, scientists will have to be able to precisely control the differentiation of stem cells into the specific cell

 

24

type to be used in therapy and drug testing. Current knowledge of the signals controlling differentiation falls well short of being able to mimic these conditions precisely to consistently have identical differentiated cells for each specified use.

To realize the promise of novel cell-based therapies for such pervasive and debilitating diseases such as diabetes and kidney cancer, scientists must be able to easily and reproducibly manipulate stem cells so that they possess the necessary characteristics for successful differentiation, transplantation and engraftment. To be useful for transplant purposes, stem cells must be reproducibly made to: proliferate extensively and generate sufficient quantities of tissue, differentiate into the desired cell type(s), survive in the recipient after transplant, integrate into the surrounding tissue after transplant, function appropriately for the duration of the recipient’s life, avoid harming the recipient in any way, and avoid the problem of immune rejection. There is no assurance that any commercialized cell-based therapies will ever be developed.

Therapies Utilizing Our Stem Cell Platform

We have developed a proprietary adult stem cell technology to produce monocyte-derived stem cells (MDSC) from blood. These MDSC can be derived from a patient’s monocytes, expanded ex vivo, and then administered to the same patient. We believe that because this is an autologous therapy, there should be no allogenic rejection issues as self-derived MDSC pose no immunological problems. Normally, allogenic cells are deleted by host immune responses and require the use of anti-rejection drugs.

Our novel multi-potent stem cell is derived from peripheral blood monocytes which when cultured under defined conditions are able to further differentiate into several cellular lineages. Molecular biology and immunohistochemical studies have shown that these MDSCs have specific markers that distinguish them from other stem cells. In addition these studies have also shown a time-dependence for the expression of these specific gene products during the growth and differentiation of MDSCs. In vitro experiments with MDSCs have shown their capacity to differentiate towards hematopoietic, epithelial, endothelial, endocrine and neuronal cells. Our main focus is the further development of this monocyte-derived stem cell technology as a novel platform for the in vitro generation of highly specialized cells for potential application in autologous cell therapy for patients with diseases such as diabetes mellitus and cardiovascular disease.

Working either alone or in conjunction with strategic partners, we intend to utilize these MDSC from the same patient to attempt to develop a therapy which may cause autologous tissue or organ repair. The initial internal therapeutic target is diabetes mellitus. Other therapeutic targets would be pursued through early-stage licensing or strategic alliances. The diabetes program is currently in pre-clinical development.

Pancreatic Islet Cell Development

Diabetes is a disease characterized by the failure or loss of pancreatic b-cells to generate sufficient levels of the hormone insulin required to meet the body’s need to maintain normal nutrient homeostasis. Type 1 diabetes is caused by the complete loss of pancreatic b-cells when the body’s own immune system mistakenly attacks and destroys a person’s b-cells. While for Type 2 diabetes the causes are far more complicated and poorly understood, the results of the disease are similar in that often the b-cells fail to generate sufficient amounts of insulin to maintain normal homeostasis. The loss of insulin results in an increase in blood glucose levels and will eventually lead to the development of premature cardiovascular disease, stroke, and kidney failure. Currently there is no permanent cure for diabetes; however, recent clinical islet cell transplantations have shown good success in restoring long-term endogenous insulin production and glycemic stability in subjects who have Type 1 diabetes mellitus with unstable baseline control. Persistent islet function without injected insulin dependence provides considerable benefit.

Current cell transplant therapy for the treatment of diabetes is limited by an inadequate supply of insulin-producing cells. Cadaveric sources are limited and up to three pancreas are required to obtain clinically

significant quantities of b-cells for one patient. The identification of novel adult human stem cells provides a new prospect for obtaining a sufficient number of insulin-producing b-cells for transplantation. Using our technology a single blood draw may be adequate to produce clinical quantities of b-cells for a patient.

In vitro experiments with MDSC have shown their capacity to differentiate toward a wide variety of cell types including pancreatic b-like cells. These cells aggregate into clusters resembling pancreatic Islets of Langerhans termed monocyte derived islets (MDI). The cluster aggregates show endocrine gene expression. Biochemical assays have demonstrated that MDI can synthesize and secrete significant amounts of insulin during their growth and respond in a glucose-dependent manner. In addition, MDI can be stimulated or repressed by the addition of agonists or antagonists of insulin in vitro.

The importance of these stem cells is the ability to easily and cost effectively derive them from an individual’s circulating monocytes, expand them and administer them back into the same patient. This autologous approach provides a method to overcome any rejection issues and the need for immunosuppressant drugs, which are often associated with current transplantations.

Stem Cell Pre-Clinical and Clinical Development

We are conducting pre-clinical studies to demonstrate proof of concept and method of delivery with a planned IND (Investigational New Drug) submission to the FDA during 2008. We hope to commence a Phase I study for monocyte-derived islet transplantation of patients with Type 1 diabetes mellitus in 2009.

Licenses, Patents and Proprietary Rights

We believe that proprietary protection of our technologies is critical to the development of our business. We intend to continue to protect our proprietary intellectual property through patents and other appropriate means. We rely upon trade-secret protection for some confidential and proprietary information and take active measures to control access to that information. We currently have non-disclosure agreements with all of our employees, consultants, vendors, advisory board members and contract research organizations.

Our intellectual property strategy includes developing proprietary technology for the sourcing, scale up, manufacturing, and storage of T cells and multipotent adult stem cells and the use of these cells in multiple therapeutic applications. This strategy will include expanding on technologies in-licensed to us as well as in-licensing additional technologies through collaborations with universities and biotech companies.

We have exclusive, worldwide licenses to certain patents that relate to our T-cell technology and our multipotent adult stem cell technology.

T-Cell Therapy Intellectual Property

We have an exclusive, worldwide license from the Baylor College of Medicine to certain patent applications relating to the treatment of MS using attenuated T-cells and to the use of the T-cell technology as a diagnostic. The license was granted to us by Baylor in exchange for common stock in Opexa Pharmaceuticals which we acquired in November 2004. The license requires us to pay royalties on sales of products covered by the license. We have filed additional patent applications related to T-Cell vaccination for MS.

Rheumatoid Arthritis Therapy Intellectual Property

We have an exclusive worldwide license for the intellectual property rights and research results of an autologous T cell vaccine for RA from the Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences of the People’s Republic of China. We made a one time $125,000 license payment and agreed to pay a royalty on net sales of products covered by the license. We have filed additional patent applications related to T-Cell vaccination for RA.

Stem Cell Therapy Intellectual Property

We have an exclusive, worldwide license from the University of Chicago, through its prime contractor relationship with Argonne National Laboratory, to a patent application related to the development of adult multipotent stem cells from monocytes isolated from adult human peripheral blood. The technology was discovered and developed at the Argonne National Laboratory, a U.S. Department of Energy Laboratory.

Pursuant to the license we have issued a total of 53,462 shares of our common stock and paid $232,742 to the University of Chicago. We will owe milestone payments upon demonstration of efficacy in Phase II clinical studies, submission for product approval to the FDA and approval of licensed products totaling $1,350,000. We will also pay royalties on net sales of products covered by the license.

We have filed additional patent applications related to the process of obtaining monocyte-derived stem cells. In addition, we have filed a patent application for the process of differentiation of MDSCs into monocyte-derived islets which function like pancreatic islet cells.

Our Product Pipeline

Multiple Sclerosis Therapy

Tovaxin is a vaccine approach for treating MS, in that it induces the body’s immune system to attack the MRTCs that we believe are responsible for destroying the myelin sheath coating of the axons in the central nervous system. We believe that the depletion and regulation of the MRTCs may stop progression of multiple sclerosis. Tovaxin is currently in a Phase IIb clinical trial. We completed enrollment of this trial in May, 2007.

Rheumatoid Arthritis Therapy

Our Rheumatoid Arthritis (RA) T-cell vaccination (TCV) technology is conceptually similar to Tovaxin. RA is an autoimmune T-cell-mediated disease in which pathogenic T-cells trigger an inflammatory autoimmune response of the synovial joints of the wrists, shoulders, knees, ankles and feet which causes pain, stiffness, and swelling around the joints. This technology is in preclinical development.

Diabetes Stem Cell Therapy

We believe that there are approximately 20.8 million people in the U.S. who have diabetes. More than 1 million of these people have Type 1 diabetes mellitus. Among adults with diagnosed diabetes, approximately 31% take insulin to control their disease. Research studies have found that improved glycemic control benefits people with either Type 1 or Type 2 diabetes. Islet transplantation using Opexa’s proprietary monocyte-derived islet cell may offer the potential to improve glycemic control in a subgroup of patients with Type 1 and Type 2 diabetes mellitus who are disabled by refractory hypoglycemia. We are in preclinical development and plan to file an IND in 2008 and initiate a Phase I clinical trial in 2009.

Other Opportunities

We intend to conduct basic research to determine the potential use of our stem cells in other indications such as macular degeneration, heart attack, and Parkinson’s disease. Liver cells (hepatocytes) derived from our stem cells may be valuable across the biopharmaceutical industry to test for drug toxicity or to help cure liver diseases. We intend to partner or sublicense some of these indications if they are not pursued for internal development. For those indications where we believe it can participate commercially, we will possibly take partners in key commercial markets outside of the United States.

Research Collaborations

We anticipate that from time to time in the future we will enter into collaborative research agreements with other academic and research institutions. We will use such agreements to enhance our research capabilities. Typically, in the industry, such agreements provide the industry partner with rights to license the intellectual property created through the collaboration. We may also enter into collaborative research agreements with other pharmaceutical companies when we believe such collaboration will support the development and commercialization of our technology.

Commercialization Through Third Parties

We anticipate that we will grant sublicenses for certain applications of our technologies. We believe that by sublicensing some of the rights to our technology to pharmaceutical companies and other third parties, we will be able to more efficiently develop some applications of our technologies. We currently do not have any sublicenses.

Competition

The development of therapeutic agents for human disease is intensely competitive. Major pharmaceutical companies currently offer a number of pharmaceutical products to treat MS, heart attack, stroke, Parkinson’s disease, diabetes, liver diseases, arthritis and other diseases for which our technologies may be applicable. Many pharmaceutical and biotechnology companies are investigating new drugs and therapeutic approaches for the same purposes, which may achieve new efficacy profiles, extend the therapeutic window for such products, alter the prognosis of these diseases, or prevent their onset. We believe that our products, when and if successfully developed, will compete with these products principally on the basis of improved and extended efficacy and safety and their overall economic benefit to the health care system. We expect competition to increase. We believe that our most significant competitors will be fully integrated pharmaceutical companies and more established biotechnology companies. Smaller companies may also be significant competitors, particularly through collaborative arrangements with large pharmaceutical or biotechnology companies. Some of our primary competitors in the current treatment of and in the development of treatments for MS include Biogen-Idec, Elan, Serono, Aventis, Teva, and Bayer/Schering AG. Some of our primary competitors in the development of stem cell therapies include Aastrom Biosciences, Geron, Gamida-Cell Ltd, Stem Cells Inc., Cellerant Therapeutics, and Osiris Therapeutics. Many of these competitors have significant products in development that could be competitive with our potential products.

Sales and Marketing

We intend to develop a sales force to market our MS cell therapy products in the U.S. Given the concentration of MS treatment among a relatively small number of specialized neurologists, we believe that a modest size sales force would be sufficient to market the MS products.

We plan to partner with large biotech and pharmaceutical companies for the marketing and sales of our MS and RA T-cell products outside the U.S. and for our stem cell therapy products.

Description of Property

Our 10,200 sq. ft. facility is located on 3 acres at 2635 North Crescent Ridge Drive in The Woodlands, Texas. This location provides space for research and development and manufacturing capacity for clinical trials; a specialized Flow Cytometry and Microscopy lab; support of clinical trials with 800 sq. ft. of GMP (good manufacturing practice) manufacturing suites; Quality Systems management with a Quality Control Laboratory, Regulatory Affairs, Quality Assurance; as well as administrative support space. There is 2,500 sq. ft. of space still available for future build-out. The facility including the property is leased for a term ending in 2015 with two options for an additional five years each at the then prevailing market rate.

Government Regulation

Our research and development activities and the future manufacturing and marketing of our potential products are, and will be, subject to regulation for safety and efficacy by a number of governmental authorities in the United States and other countries.

In the U.S., pharmaceuticals, biologicals and medical devices are subject to FDA regulation. The Federal Food, Drug and Cosmetic Act, as amended, and the Public Health Service Act, as amended, the regulations promulgated thereunder, and other Federal and state statutes and regulations govern, among other things, the testing in human subjects, manufacture, safety, efficacy, labeling, storage, export, record keeping, approval, marketing, advertising and promotion of our potential products. Product development and approval within this regulatory framework takes a number of years and involves significant uncertainty combined with the expenditure of substantial resources.

FDA Approval

We will need to obtain FDA approval of any therapeutic product we plan to market and sell. The testing and approval process will require substantial time, effort and expense. The steps required before our potential products may be marketed in the U.S. include:

Preclinical Laboratory and Animal Tests. Preclinical tests include laboratory evaluation of the product and animal studies in specific disease models to assess the potential safety and efficacy of the product and our formulation as well as the quality and consistency of the manufacturing process.

Submission to the FDA of an Application for an Investigational New Drug Exemption, or IND, Which Must Become Effective Before U.S. Human Clinical Trials May Commence. The results of the preclinical tests are submitted to the FDA as part of an IND, and the IND becomes effective 30 days following its receipt by the FDA, as long as there are no questions, requests for delay or objections from the FDA. The sponsor of an IND must keep FDA informed during the duration of the study through required amendments and reports, including adverse event reports.

Adequate and Well-Controlled Human Clinical Trials to Establish the Safety and Efficacy of the Product. Clinical trials, which test the safety and efficacy of the product in humans, are conducted in accordance with protocols that detail the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Any product administered in a U.S. clinical trial must be manufactured in accordance with Current Good Manufacturing Practice (cGMP or GMP). Each protocol is submitted to the FDA as part of the IND.

The protocol for each clinical study must be approved by an independent Institutional Review Board, or IRB, at the institution at which the study is conducted and the informed consent of all participants must be obtained. The IRB will consider, among other things, the existing information on the product, ethical factors, the safety of human subjects, the potential benefits of the therapy and the possible liability of the institution.

Clinical development is traditionally conducted in three sequential phases, which may overlap:

 

   

In Phase I, products are typically introduced into healthy human subjects or into selected patient populations (i.e., patients with a serious disease or condition under study, under physician supervision, as may be the case with our potential products) to test for adverse reactions, dosage tolerance, absorption and distribution, metabolism, excretion and clinical pharmacology.

 

   

Phase II involves studies in a limited population of patients with the disease or condition under study to (i) determine the efficacy of the product for specific targeted indications and populations, (ii) determine optimal dosage and dosage tolerance and (iii) identify possible and common adverse effects and safety

 

29

risks. (Phase II may divided into Phase IIa and Phase IIb studies to address these issues.) When a dose is chosen and a candidate product is found to have preliminary evidence of effectiveness, and to have an acceptable safety profile in Phase II evaluations, Phase III trials begin

 

   

Phase III trials are undertaken to develop additional safety and effectiveness information from an expanded patient population, generally at multiple study sites. This information obtained is used to develop a better understanding of the risks and benefits of the product, and to determine appropriate labeling for use.

Based on clinical trial progress and results, FDA may request changes or may require discontinuance of the trials at any time if significant safety issues arise.

Submission to the FDA of Marketing Authorization Applications. The results of the preclinical studies and clinical studies are submitted to the FDA in the form of marketing approval authorization applications such as New Drug Applications (NDAs) or Biologics License Applications (BLAs). A BLA is required for biological products subject to licensure under the Public Health Service Act. FDA approval is required prior to commercial sale or shipment of the drug or biologic, and a BLA shall only be approved once FDA examines the product and inspects the manufacturing establishment to assure conformity to the BLA and all applicable regulations. The Center for Biologics Evaluation and Research has regulatory responsibility for review of biologics including cellular products and human cells, tissues and cellular and tissue-based products (HCT/Ps), while the Center for Drug Evaluation and Research is responsible for review of certain therapeutic biological products.

The time for approval may vary widely depending on the specific product and disease to be treated, and a number of factors, including the risk/benefit profile identified in clinical trials, the availability of alternative treatments, and the severity of the disease. Additional animal studies or clinical trials may be requested during the FDA review period, which might add to the review time.

FDA’s marketing approval for a product for the treatment of a specific disease or condition in specified populations in certain clinical circumstances, as described on the approved labeling. The approved use is known as the “indication.” After FDA approves a product for the initial indication, further clinical trials may be required to gain approval for the use of the product for additional indications. The FDA may also require post-marketing testing and surveillance to monitor for adverse effects, which could involve significant expense, or may elect to grant only conditional approvals.

Interaction with FDA During the Application and Review Process. Generally, early interaction and ongoing communication with FDA can facilitate the testing and approval process by helping to clarify FDA expectations, obtain FDA guidance and directions, and resolve disputed issues. In addition, expectations can be formalized in a “Special Protocol Assessment,” in which FDA provides official evaluation and guidance on proposed protocols for pivotal Phase III clinical trials. An SPA documents the FDA’s agreement that the design and plan analysis of the Phase III study adequately addresses objectives in support of a regulatory submission such as a BLA.

Ongoing Compliance Requirements

Even after product approval or licensure, there are a number of ongoing FDA regulatory requirements, including:

 

   

Regulatory submissions relating to changes in an NDA or BLA (such as the manufacturing process or labeling) and annual reports;

 

   

Adverse event reporting;

 

   

Compliance with advertising and promotion restrictions that relate to drugs and biologics;

 

   

Compliance with GMP (subject to FDA inspection of facilities to determine compliance);

 

30

Index to Financial Statements
   

Compliance with “Good Tissue Practice” regulations, as applicable. (As defined by regulation, “human cell, tissue and cellular and tissue-based products” (HCT/P), which are subject to additional regulatory requirement, include stem cells that are progenitors of blood cells; however, the FDA makes no explicit statement in the regulations regarding the inclusion of other types of stem cells.)

Other Regulations

In addition to safety regulations enforced by the FDA, we are also subject to regulations under the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act and other present and potential future foreign, Federal, state and local regulations. For instance, Product manufacturing establishments located in certain states also may be subject to separate regulatory and licensing requirements.

Outside the U.S., we will be subject to regulations that govern the import of drug products from the U.S. or other manufacturing sites and foreign regulatory requirements governing human clinical trials and marketing approval for our products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursements vary widely from country to country. In particular, the European Union is revising its regulatory approach to high tech products, and representatives from the U.S., Japan and the European Union are in the process of harmonizing and making more uniform the regulations for the registration of pharmaceutical products in these three markets.

Employees

As of December 18, 2007, we had 40 full time employees. We believe that our relations with our employees are good. None of our employees is represented by a union or covered by a collective bargaining agreement.

Legal Proceedings

We are not currently a party to any legal proceedings.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of December 18, 2007, the number and percentage of outstanding shares of our common stock owned by: (a) each person who is known by us to be the beneficial owner of more than 5% of our outstanding shares of common stock; (b) each of our directors; (c) the named executive officers as defined in Item 402 of Regulation S-B; and (d) all current directors and executive officers, as a group. As of December 18, 2007, there were 6,696,784 shares of common stock issued and outstanding.

Beneficial ownership has been determined in accordance with Rule 13d-3 under the Exchange Act. Under this rule, certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire shares (for example, upon exercise of an option or warrant) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares is deemed to include the amount of shares beneficially owned by such person by reason of such acquisition rights. As a result, the percentage of outstanding shares of any person as shown in the following table does not necessarily reflect the person’s actual voting power at any particular date.

To our knowledge, except as indicated in the footnotes to this table and pursuant to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them.

DESCRIPTION OF SECURITIES

Our Capitalization

Common Stock

We are authorized to issue 100,000,000 shares of common stock, par value $0.50 per share. As of January 3, 2008, there were 6,696,784 shares of common stock issued and outstanding. Each share of common stock is entitled to one vote per share for the election of directors and on all other matters submitted to a vote of stockholders. There are no cumulative voting rights. Common stockholders do not have preemptive rights or other rights to subscribe for additional shares, and the common stock is not subject to conversion or redemption. In the event of liquidation, the holders of common stock will share equally in any balance of corporate assets available for distribution to them. Subject to the rights of holders of the any other securities subsequently issued, holders of the common stock are entitled to receive dividends when and as declared by our Board of Directors out of funds legally available. We have not paid any dividends since our inception and have no intention to pay any dividends in the foreseeable future. Any future dividends would be subject to the discretion of the Board of Directors and would depend on, among other things, our future earnings, the operating and financial condition, our capital requirements, and general business conditions.

Preferred Stock

We are authorized to issue 10,000,000 shares of preferred stock, no par value per share. As of January 3, 2008, no shares of preferred stock are issued and outstanding. Our Board of Directors can, without approval of our stockholders, issue one or more series of preferred stock. If we issue preferred stock, our Board of Directors will determine the number of shares and the rights, preferences and limitations of each series. These rights, preferences and limitations may include specific designations, number of shares, liquidation value, dividend rights, liquidation and redemption rights and voting rights.

Warrants and Options

2004 Stock Incentive Plan. Pursuant to our 2004 Stock Incentive Plan we may issue to our officers, directors, employees and consultants incentive stock options, non-qualified stock options and shares of restricted stock. The plan provides for us to issue up to 1,200,000 shares of its common stock pursuant to awards under the plan. As of January 3, 2008 we had outstanding options, granted pursuant to the plan, to purchase 1,043,925 shares of common stock. The plan is designed to qualify under the Internal Revenue Code as an incentive stock option plan.

Series E Warrants. We are offering 4,500,000 Series E warrants in the offering. Each Series E warrant permits the holder to purchase one share of our common stock at an exercise price of $            (125% of the offering price of a share of common stock). The Series E warrants may be exercised at any time commencing the date of issuance until the five year anniversary of issuance at 5:00 p.m., New York City time, on such date.

We may call the Series E warrants for redemption (excluding any Series E warrants issued or issuable to the underwriters under their warrant purchase option), in whole and not in part, at a price of $.01 per Series E warrant at any time while the Series E warrants are exercisable, upon not less than 30 days’ prior written notice of redemption to each warrant holder, and if, and only if, the average of the last sale prices of the common stock equals or exceeds $            [200% of the then exercise price of the warrants] per share, for the consecutive 20 trading days ending within 10 business days prior to the notice of redemption to warrant holders. In addition, we may only call the Series E Warrants for redemption if we have an effective registration statement available for the issuance of the shares on exercise or, if we don’t have an effective registration statement, we can issue the shares without legend pursuant to Rule 144. In connection with the call provision on the basis of a cashless exercise, we will determine if we will pursue the redemption without a registration statement, and as part of the

call notice, indicate the market price at which a cashless exercise will be calculated. The market price will be the highest price of a share of common stock during the period used to determine if we may call the warrants for redemption.

Under the terms of the warrant agreement, we have agreed to take steps to have a prospectus relating to common stock issuable upon exercise of the Series E warrants is current and the common stock has been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants and use our best efforts to maintain a current prospectus relating to common stock issuable upon exercise of the Series E warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so, and if we do not maintain a current prospectus related to the common stock issuable upon exercise of the warrants, holders may be unable to exercise their Series E warrants and we may not be required to settle any such warrant exercise. If the prospectus relating to the common stock issuable upon the exercise of the Series E warrants is not current or if the common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the Series E warrants reside, then the Series E warrant may only be exercised either through a cashless exercise or by a cash exercise after the warrant holder makes such representations that are required by us to ensure compliance with applicable securities laws.

We are also providing for a cashless exercise of the Series E Warrants prior to a redemption if there is no effective registration statement available for a cash exercise, provided that if the shares of common stock to be issued on exercise cannot be delivered without legend because the holding period for Rule 144 has not passed (currently two years), the holder will be required to make the exercise by obtaining a certificate from the warrant agent, and then presenting the physical certificate and the exercise form to the company. Any shares issued under this aspect of the cashless exercise provision, will be issued with a restrictive legend. Therefore, the shares received on such exercise may not be traded unless there is an exemption from registration available. This exemption may be Rule 144, which currently provides that after a one year holding period of the securities being sold, the holder may effect a market sale, through a broker, within volume limitations, provided there is current information about the company available, a notice filing is made by the holder with the Securities and Exchange Commission. Anyone exercising on a cashless basis will have to bear the risk of holding restricted stock for an indefinite period of time. If the cashless exercise is after the holding period of Rule 144, then it may be effected without presentation of a physical certificate and the shares to be issued on such exercise will be not be issued as restricted stock.

In a “cashless exercise”, holders of Series E warrants would pay the exercise price by surrendering his, her or its Series E warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the Series E warrants and the “market price” (defined below) by (y) the market price. The “market price” shall mean the last sale price of the common stock on the date of exercise unless it is in connection with a redemption of the Series E warrants in which case it will be the highest price of a share of common stock during the period used to determine if we may call the warrants for redemption. A cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption, but we will not receive any cash proceeds.

The Series E warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. You should review a copy of the warrant agreement, which has been filed as an exhibit to the registration statement of which this prospectus is a part, for a complete description of the terms and conditions applicable to the warrants.

The exercise price and number of shares of common stock issuable on exercise of the Series E warrants may be adjusted in certain circumstances including in the event of a stock dividend, or our recapitalization, reorganization, merger or consolidation. However, the Series E warrants will not be adjusted for issuances of common stock at a price below their respective exercise prices.

The Series E warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of Series E warrants being exercised. The warrant holders do not have the rights or privileges of holders of common stock and any voting rights until they exercise their Series E warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round up to the nearest whole number the number of shares of common stock to be issued to the warrant holder.

Series C Warrants. As of January 3, 2008 we have outstanding Series C Warrants to purchase an aggregate of 1,110,548 of our common shares. The Series C Warrants are exercisable at any time at an exercise price of $30.00 per share and expire on June 17, 2010. The Series C Warrants are exercisable immediately and are only exercisable by “accredited investors” as defined in Regulation D under the Securities Act of 1933.

April 2006 Warrants. In an offering consummated April 17, 2006, we issued warrants to acquire an aggregate of 2,300,000 shares. The April 2006 warrants have an exercise price of $6.50 per share. We have the right to call the April 2006 warrants at any time if the closing bid price per share of our common stock equals or exceeds $13.00 for twenty consecutive trading days in which the daily average trading volume of the common stock is at least 20,000 shares.

Placement Agent Warrants. In connection with the 15% Convertible Exchangeable Note offering and the common stock offerings closed June 17, 2005, we issued to the placement agent and other brokerage firms in those offerings warrants to purchase an aggregate of 46,085 shares of common stock at an exercise price of $15.00. These warrants are exercisable immediately and will expire June 17, 2010.

Restrictions on Sales By Certain Existing Shareholders. A total of 250,000 shares held by Top Tier Investment, LLC and various other shareholders are subject to a lock-up agreement effective November 5, 2004 that limits sales to an aggregate of 31,250 shares of our common stock per 90-day period. There is no termination provision in this lock-up agreement.

Purchase Option

We have agreed to sell to the underwriters an option to purchase up to a total of 450,000 shares of common stock at an exercise price of $             per share, and an option to purchase up to a total of 450,000 Series E warrants at an exercise price of $.018 per warrant. The common stock and Series E warrants are identical to those offered by this prospectus.

Dividends

We have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends prior to the completion of a business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition. The payment of any dividends is within the discretion of our then board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in our business operations and, accordingly, our board does not anticipate declaring any dividends in the foreseeable future.

Our Transfer Agent and Warrant Agent

The transfer agent for our securities and warrant agent for our Series E warrants is Continental Stock Transfer & Trust Company, 17 Battery Place, New York, New York 10004.

Persons who receive this prospectus are advised to inform themselves about and to observe any restrictions relating to this offering of our common stock and Series E warrants and the distribution of this prospectus.

We have agreed to pay to the underwriters a non-accountable expense allowance equal to 1% of the gross proceeds from the sale of the shares of common stock and Series E warrants offered by us (excluding the over-allotment), of which $25,000 has been paid by us as of the date of this prospectus. We have also agreed to pay all expenses in connection with qualifying the shares offered hereby under the laws of the states designated by the underwriters. We estimate the expenses payable by us for this offering to be $             , including the underwriting discount, or $             if the underwriters’ over-allotment option is exercised in full.

Over-allotment option

We have granted to the underwriters an option, exercisable not later than 45 days after the date of this prospectus, to purchase up to an additional 675,000 shares of our common stock and 675,000 Series E warrants at the public offering price, less the underwriting discount, set forth on the cover page of this prospectus. The representative may exercise the option solely to cover over-allotments, if any, made in connection with this offering. If any additional shares of our common stock or Series E warrants are purchased pursuant to the over-allotment option, the underwriters will offer these additional shares and Series E warrants on the same terms as those on which the other shares and Series E warrants are being offered hereby.

Determination of offering price

The public offering prices of the common stock and Series E warrants were negotiated between us and the representative of the underwriters, based on the trading prior to the offering, among other things. Other factors considered in determining the price of the securities include the history and prospects of the company, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

Lock-Up Agreements

We will agree, for a period of 180 days from the date of this prospectus, subject to certain exceptions, not, to offer, sell, contract to sell, pledge or otherwise dispose of, enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission, or the SEC, in respect of, any shares of capital stock of the Company or any securities convertible into, or exercisable or exchangeable for such capital stock, for the Company’s account, without the prior written consent of MDB Capital Group LLC. Certain of our executive officers and directors will agree to substantially similar terms for a period of 180 days pursuant to individual lock-up agreements. The foregoing restrictions on sales will not apply to our ability to sell securities to the underwriter pursuant to the underwriting agreement. In addition, the foregoing restrictions will not apply to our ability to issue our common stock pursuant to our existing stock option and employee stock purchase plans or under outstanding securities convertible into or exercisable for common stock.

Indemnification

We will agree to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The underwriters may engage in over-allotment, stabilizing transactions, syndicate covering transactions, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the common stock, in accordance with Regulation M under the Exchange Act of 1934:

 

   

Over-allotment involves sales by the underwriter of shares and warrants in excess of the number of shares and warrants the underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares and warrants over-allotted by an underwriter is not greater than the number of shares and warrants that it may purchase in the over-allotment option. In a naked short position, the number of shares and warrants involved is greater than the number of shares and warrants in the over-allotment option. The underwriter may close out any short position by either exercising its over-allotment option and/or purchasing shares and warrants in the open market.

 

   

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum;

 

   

Syndicate covering transactions involve purchases of the common stock and warrants in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares and warrants to close out the short position, the underwriter will consider, among other things, the price of shares and warrants available for purchase in the open market as compared to the price at which it may purchase shares through the over-allotment option. If an underwriter sells more shares and warrants than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares and warrants in the open market. A naked short position is more likely to be created if an underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

 

   

Penalty bids permit an underwriter to reclaim a selling concession from a syndicate member when the shares and warrants originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock and warrants or preventing or retarding a decline in the market price of the common stock or warrants. As a result, the price of the common stock or warrants may be higher than the price that might otherwise exist in the open market. These transactions may be effected on The NASDAQ Capital Market, in the case of the common stock or of the warrants, or otherwise and, if commenced, may be discontinued at any time.

Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock or warrants. In addition, neither we nor the underwriters make any representation that the underwriters will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Passive Market Making

In connection with the offering, the underwriters and selling group members may engage in passive market making transactions in the common stock and Series E warrants on The NASDAQ Capital Market in accordance with Rule 103 of Regulation M under the Securities Exchange Act of 1934 during the period before the commencement of offers or sales of common stock and Series E warrants and extending through the completion of distribution. A passive market maker must display its bids at a price not in excess of the highest independent bid of the security. However, if all independent bids are lowered below the passive market maker’s bid, that bid must be lowered when specified purchase limits are exceeded.

Electronic Distribution

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by the underwriters and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares and Series E warrants for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations.

Other than the prospectus in electronic format, the information on an underwriter’s or a selling group member’s website and any information contained in any other website maintained by the underwriter or selling group member is not part of the prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

Underwriter’s Warrants

We will agree to issue to the underwriters warrants to purchase up to a total each of 450,000 shares of common stock and of 450,000 Series E warrants. The warrants will be exercisable at an exercise price of $             per share and $             per warrant (120% of the public prices). The underwriters’ warrants and the shares and Series E warrants underlying the warrants may not be sold, transferred, assigned, pledged or hypothecated for a period of either six months or one year from the date of this prospectus, as may be agreed to by us and the underwriters, except to officers of the underwriters and members of the selling group and/or their officers and partners. The exercise prices and number of shares and Series E warrants issuable upon exercise of the underwriters’ warrants may be adjusted in certain circumstances including in the event of a stock dividend, or our recapitalization, reorganization, merger or consolidation.

Relationships

In October 2005, we engaged MDB Capital Group LLC as placement agent for a private financing. In connection with the financing completed April 2006, MDB Capital Group LLC acquired 200,000 shares of the Company’s common stock and a Warrant to purchase 100,000 shares of the Company’s common stock, and received $1,723,300 for its services and a three year warrant to purchase 208,330 shares of our common stock at $5.00 per share.

The underwriter’s compensation in connection with this offering is limited to the fees and expenses described above under “Commissions and Expenses” and to its warrants as described above under “Underwriter’s Warrants.”

We have no other arrangements with any of the underwriters following completion of this offering. The underwriters may, however, from time to time, engage in transactions with or perform services for us in the ordinary course of its business.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors

Opexa Therapeutics, Inc.

(formerly PharmaFrontiers Corp.)

(a development stage company)

The Woodlands, Texas

We have audited the accompanying consolidated balance sheet of Opexa Therapeutics, Inc. (a development stage company), as of December 31, 2006 and the related consolidated statements of expenses, changes in stockholders’ equity and cash flows for the years ended December 31, 2006 and 2005 and the period from January 22, 2003 (Inception) through December 31, 2006. These consolidated financial statements are the responsibility of Opexa’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatements. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Opexa as of December 31, 2006 and the consolidated results of its operations and its cash flows for the periods described in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the financial statements, the Company has restated its financial statements for the years ended December 31, 2006 and 2005 and the period from January 22, 2003 (Inception) through December 31, 2006 as they relate to the accounting for acquired in process research and development.

As discussed in Note 15 to the consolidated financial statements, the accompanying consolidated financial statements have been prepared assuming that Opexa will continue as a going concern. Opexa requires significant amount of cash in its operations and does not have sufficient cash to fund its operations for the next twelve months, which raises substantial doubt about its ability to continue as a going concern. Management’s plans regarding those matters are also described in Note 15. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

(a development stage company)

(formerly PharmaFrontiers Corp.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—SUMMARY OF ACCOUNTING POLICIES

Opexa Therapeutics, Inc. (“Opexa”), was incorporated in Texas in March, 1991 as a bio-pharmaceutical company engaged in developing autologous personalized cell therapies. During the development stage, Opexa acquired the worldwide license to technology developed at Argonne National Laboratory, a U.S. Department of Energy Laboratory Operated by the University of Chicago (“Argonne”). This is an exclusive license to a stem cell technology in which adult multi-potent stem cells are derived from monocytes obtained from the patient’s own blood (the “License”). A patent application was filed in November 2003, with the United States Patent and Trade Office regarding the technology involved in the License.

On October 7, 2004, Opexa acquired all of the outstanding stock of Opexa Pharmaceuticals, Inc., an entity that has the exclusive worldwide license from Baylor College of Medicine to an individualized T-cell therapeutic vaccine, Tovaxin, which is in U.S. FDA Phase IIb human clinical trials to evaluate its safety and effectiveness in treating multiple sclerosis.

Development Stage Company. The Company is considered to be in the Development stage as defined in Statement of Financial Accounting Standards No. 7. The Company has no revenues to date.

Basis of Presentation. In June 2006, the Company (i) changed its name to Opexa Therapeutics, Inc. from PharmaFrontiers Corp. and (ii) effected a one-for-ten reverse common stock split. All references to number of shares and per share amounts reflect such split as if it occurred on the first day of the first period presented. The consolidated financial statements include the accounts of Opexa Therapeutics, Inc. and its wholly-owned subsidiary, Opexa Pharmaceuticals, Inc. Significant inter-company accounts and transactions have been eliminated.

Reclassifications. Certain prior year amounts have been reclassified to conform with the current year presentation.

Use of Estimates in Financial Statement Preparation. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash, Cash Equivalents and Marketable Securities. For purposes of the statements of cash flows, cash equivalents include all highly liquid investments with original maturities of three months or less. Marketable securities include investments with maturities greater than three months but less than one year. The primary objectives for the fixed income investment portfolio are liquidity and safety of principal. Investments are made with the objective of achieving the highest rate of return consistent with these two objectives. Opexa’s investment policy limits investments to certain types of instruments issued by institutions primarily with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer.

Long-lived Assets. Property and equipment are stated on the basis of historical cost less accumulated depreciation. Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Major renewals and improvements are capitalized, while minor replacements, maintenance and repairs are charged to current operations. Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount.

Income Taxes. Income tax expense is based on reported earnings before income taxes. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for consolidated financial reporting purposes and such amounts recognized for tax purposes, and are measured by applying enacted tax rates in effect in years in which the differences are expected to reverse.

Stock-Based Compensation. On January 1, 2006, Opexa began recording compensation expense associated with stock options and other forms of equity compensation in accordance with Statement of Financial Accounting Standards No. 123R, Share-Based Payment, as interpreted by SEC Staff Accounting Bulletin No. 107. Prior to January 1, 2006, Opexa had accounted for stock options according to the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations, and therefore no related compensation expense was recorded for awards granted with no intrinsic value. Opexa adopted the modified prospective transition method provided for under SFAS No. 123R, and, consequently, have not retroactively adjusted results from prior periods. Under this transition method, compensation cost associated with stock options recognized in the first quarter of fiscal 2006 includes the quarterly amortization related to the remaining unvested portion of all stock option awards granted prior to January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123.

The following table illustrates the effect on net loss and net loss per share if Opexa had applied the fair value provisions of FASB Statement No. 123 to stock-based employee compensation prior to January 1, 2006:

Research and Development. Research and development expenses include salaries, related employee expenses, clinical trial expenses, research expenses, consulting fees, and laboratory costs. All costs for research and development activities are expensed as incurred. Opexa expenses the costs of licenses of patents and the prosecution of patents until the issuance of such patents and the commercialization of related products is reasonably assured. Acquired in process research and development that does not have a future alternative use is expensed when acquired. Research and development expense for the year ended December 31, 2006 was 7,850,372, as compared to $5,159,853 for the year ended December 31, 2005.

Accounting for Derivative Instruments. Statement of Financial Accounting Standard (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended, requires all derivatives to be recorded on the balance sheet at fair value. Opexa’s derivatives are separately valued and accounted for on our balance sheet. Fair values for securities traded in the open market and derivatives are based on quoted market prices. Where market prices are not readily available, fair values are determined using market based pricing models incorporating readily observable market data and requiring judgment and estimates.

The pricing model Opexa used for determining fair values of its derivatives is the Black Scholes Pricing Model. Valuations derived from this model are subject to ongoing internal and external verification and review. The model uses market-sourced inputs such as interest rates, exchange rates and option volatilities. Selection of these inputs involves management’s judgment and may impact net income.

In September 2000, the Emerging Issues Task Force (“EITF”) issued EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in, a Company’s Own Stock,” (“EITF 00-19”) which Requires freestanding contracts that are settled in a company’s own stock, including common stock warrants, to be designated as an equity instrument, asset or a liability. Under the provisions of EITF 00-19, a contract designated as an asset or a liability must be carried at fair value on a company’s balance sheet, with any changes in fair value recorded in the company’s results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required.

In December 2006, the FASB issued FASB Staff Position No. EITF 00-19-2, Accounting for Registration Payment Arrangements (EITF 00-19-2). EITF 00-19-2 addresses an issuer’s accounting for registration payment arrangements. It specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. The guidance in EITF 00-19-2 amends FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and FASB Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, to include scope exceptions for registration payment arrangements. EITF 00-19-2 also requires additional disclosure regarding the nature of any registration payment arrangements, alternative settlement methods, the maximum potential amount of consideration and the current carrying amount of the liability, if any. This EITF is effective immediately for registration payment arrangements and the financial instruments subject to those arrangements that are entered into or modified subsequent to the date of issue of this EITF. For registration payment arrangements and financial instruments subject to those arrangements that were entered into prior to the issuance of this EITF, this is effective for financial statements issued for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. The impact of implementing EITF 00-19-2 in the fiscal year 2007 will result in a cumulative effect of a change in accounting principle with a credit to beginning retained earnings of $6,656,677 and a reversal of the same amount to the derivative liability account.

Recently Issued Accounting Pronouncements.

In February 2006, the FASB issued SFAS 155, “Accounting for Certain Hybrid Financial Instruments,” which amends SFAS 133, “Accounting for Derivative Instruments and Hedging Activities” and SFAS 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.” SFAS 155 simplifies the accounting for certain derivatives embedded in other financial instruments by allowing them to be accounted for as a whole if the holder elects to account for the whole instrument on a fair value basis. SFA 155 also clarifies and amends certain other provisions of SFAS 133 and SFAS 140. SFAS 155 is effective for all financial instruments acquired, issued or subject to a remeasurement event occurring in fiscal years beginning after September 15, 2006 and is therefore required to be adopted by the Company as of October 1, 2006. Management is still evaluating what effect this will have on the Company’s financial statements.

In July 2006, the FASB issued Interpretation No. 48 (FIN No. 48), “Accounting for Uncertainty in Income Taxes.” This interpretation requires recognition and measurement of uncertain income tax positions using a “more-likely-than-not” approach. FIN No. 48 is effective for fiscal years beginning after December 15, 2006. Management is still evaluating what effect this will have on the Company’s financial statements.

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements.” This standard defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosure about fair value measurements. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. Early adoption is encouraged. The adoption of SFAS 157 is not expected to have a material impact on the financial statements.

There were various other accounting standards and interpretations issued during 2006 and 2005, none of which are expected to have a material impact on the Company’s consolidated financial position, operations or cash flows.

NOTE 2—RESTATEMENT OF FINANCIAL STATEMENTS

The Company is restating these financial statements for the 2006, 2005 and 2004 annual periods.

Following is a description of the restatements to the financial statements:

The Company acquired Opexa Pharmaceuticals in October 2004 and originally accounted for the acquired in process research and development of $23,991,128 as intangible assets. In November 2007, the Company re-evaluated its accounting for acquired research and development and upon further consideration of Paragraph 11(c) of Statement of Financial Accounting Standards No. 2 (SFAS No. 2) and accounting guidance from Financial Accounting Standards Board Interpretation No. 4 “Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method” (FIN 4), the Company determined that these assets did not have an alternative future use at the date of acquisition. Thus, they had no separate economic value and should be accordingly expensed to research and development in the period acquired.

In February 2004, the Company obtained a license from the University of Chicago for an adult stem cell technology. Costs associated with the acquisition of this license were originally accounted for as an intangible asset. The amounts originally capitalized as intangible assets were $3,051,706, $976,497 and $112,440 for the years ended December 31, 2004, 2005 and 2006 respectively. Upon further consideration of Paragraph 11(c) of SFAS No. 2, the Company determined that these assets had not reached technological feasibility at the date of acquisition and had no alternative future use. Therefore, the intangible asset should have been expensed to in process research and development in the period acquired.

In March 2006, the Company obtained an exclusive worldwide license for the intellectual property rights and research results of an autologous T cell vaccine for rheumatoid arthritis from the Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences of the People’s Republic of China. The Company made a $125,000 license payment and accounted for the license as an intangible asset. Upon further consideration of Paragraph 11(c) of SFAS No. 2, the Company determined that this asset had not reached technological feasibility at the date of acquisition and had no alternative future use. Therefore, the intangible asset should have been expensed to in process research and development in the period acquired.

Depreciation is calculated by the straight-line method over the estimated useful life of three to ten years, depending upon the type of equipment, except for leasehold improvements which are amortized using the straight-line method over the remaining lease term or the life of the asset, whichever is shorter. The cost of repairs and maintenance is charged as an expense as incurred. Depreciation expense totaled $174,117 and $98,080 in fiscal 2006 and 2005, respectively.

NOTE 6—INCOME TAXES

Opexa uses the liability method, where deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities for financial and income tax reporting purposes.

At December 31, 2006, for federal income tax and alternative minimum tax reporting purposes, the Company had approximately $56,106,251 of unused net operating losses available for carryforward to future years. The benefit from carryforward of such net operating losses will expire in various years through 2026. Under the provisions of Section 382 of the Internal Revenue Code, the benefit from utilization of approximately $5,650,429 of net operating losses incurred prior to October 7, 2004 was significantly limited as a result of the change of control that occurred in connection with the Company’s acquisition of Opexa. The benefit could be subject to further limitations if significant future ownership changes occur in the Company.

NOTE 12—PURCHASE OF OPEXA PHARMACEUTICALS

In October 2004, Opexa acquired all of the outstanding stock of Opexa Pharmaceuticals, Inc. The acquisition was accounted for under the purchase method, where all of Opexa Pharmaceuticals, Inc.’s assets are restated to their fair market value on the acquisition date. The 250,000 shares of Opexa were valued at their then fair value of $23,750,000 or $95.00 per share. The results of operations for Opexa from November 6, 2004 through December 31, 2005 are included in the Statements of Operations and the Statements of Cash Flows.

The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition:

 

Current assets

   $ 55,387  

Property, plant and equipment, net

     639,160  

Acquired in process research and development

     23,991,128  

Current liabilities assumed

     (935,675 )
        

Total allocation of purchase price

   $ 23,750,000  
        

The estimated fair value of acquired in process research and development of $23,991,128 was determined by our management. Management considered a number of factors in determining the value of the acquired in process research and development, including the results of an independent valuation performed by a third-party valuation specialist. The purchased represents Opexa Pharmaceuticals’ incomplete research and development programs that had not yet reached technological feasibility and had no alternative future uses as of the acquisition date and, therefore, was expensed upon acquisition within our Consolidated Statements of Expenses.

NOTE 13—DERIVATIVE INSTRUMENTS

For the years ended December 31, 2006 and 2005, Opexa evaluated the application of SFAS 133 and EITF 00-19 for all of its financial instruments and identified the following financial instruments as derivatives:

(1) Series A Warrants issued in conjunction with the bridge note exchange and private placement offerings in June and July 2005, which expired on February 17, 2006;

(2) Series B Warrants issued in conjunction with the bridge note exchange and private placement offerings in June and July 2005, which expired on October 17, 2006; and

(3) Series C Warrants issued in conjunction with the bridge note exchange and private placement offerings in June and July 2005.

These three series of warrants are derivatives because the liquidated damage provision in the registration rights agreement covering each warrant resulted in the conclusion that it was more economic to issue registered shares than to issue unregistered shares and pay the penalty. Because issuing registered shares is outside of Opexa’s control, Opexa concluded the warrants should be accounted for as derivative liabilities under SFAS 133 and EITF 00-19.

As a result, Opexa reports the value of these derivatives as current liabilities in its balance sheet and report changes in the value of these derivatives as non-operating gains or losses in its statements of operations. The value of the derivatives is required to be remeasured on a quarterly basis, and is based on the Black Scholes Pricing Model.

The warrants granted during the April 2006 financing were determined to qualify as for equity treatment under SFAS 133 and EITF 00-19. Nothing in the warrant agreements required cash settlement or allowed for the possibility of cash settlement including the impact of the liquidated damages penalty under the registration rights agreement. It was determined on the date of grant and at December 31, 2006 that it was more economic to issue unregistered shares and pay the penalty than to issue registered shares.

In December 2006, the FASB issued FASB Staff Position No. EITF 00-19-2, Accounting for Registration Payment Arrangements (EITF 00-19-2). EITF 00-19-2 addresses an issuer’s accounting for registration payment arrangements. It specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. The guidance in EITF 00-19-2 amends FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and FASB Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, to include scope exceptions for registration payment arrangements. EITF 00-19-2 also requires additional disclosure regarding the nature of any registration payment arrangements, alternative settlement methods, the maximum potential amount of consideration and the current carrying amount of the liability, if any. This EITF is effective immediately for registration payment arrangements and the financial instruments subject to those arrangements that are entered into or modified subsequent to the date of issue of this EITF. For registration payment arrangements and financial instruments subject to those arrangements that were entered into prior to the issuance of this EITF, this is effective for financial statements issued for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. The impact of implementing EITF 00-19-2 in the fiscal year 2007 will result in a cumulative effect of a change in accounting principle with a credit to beginning retained earnings of $6,656,677 and a reversal of the same amount to the derivative liability account.

NOTE 14—STOCK PURCHASE AGREEMENT

In June 2004, Pharma was acquired by Sportan United Industries, Inc. in a transaction accounted for as a reverse acquisition. Pharma’s shareholders were issued 6,386,439 Sportan shares in exchange for 100 percent of the outstanding common shares of Pharma. Immediately following this transaction, Sportan changed its name to Pharma and 7,383,838 shares were outstanding.

NOTE 15—GOING CONCERN

On November 2, 2007, Opexa filed it quarterly report for the period ended September 30, 2007. As shown in its financial statements, Opexa has negative cash flows provided by its operating activities and has a cash balance of $5.8 million as of September 30, 2007 which is not sufficient to fund its operations for the next twelve months. These conditions raise substantial doubt as to Opexa’s ability to continue as a going concern. Management will seek to raise additional capital through sales of convertible debt and/or equity. The financial statements do not include any adjustments that might be necessary if Opexa is unable to continue as a going concern.

NOTES TO FINANCIAL STATEMENTS

(unaudited)

NOTE 1—BASIS OF PRESENTATION

The accompanying unaudited interim financial statements of Opexa Therapeutics, Inc., a development stage company, have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules of the Securities and Exchange Commission and should be read in conjunction with the audited financial statements and notes thereto contained in Opexa’s latest Annual Report filed with the SEC on Form 10-KSB. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of financial position and the results of operations for the interim periods presented have been reflected herein. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Notes to the financial statements that would substantially duplicate the disclosure contained in the audited financial statements for the most recent fiscal year as reported in Form 10-KSB, have been omitted.

NOTE 2—GOING CONCERN

Opexa incurred a net loss of approximately $10.7 million for the nine months ended September 30, 2007 and has an accumulated deficit of approximately $73.9 million Cash balance of $5.8 million as of September 30, 2007 is not sufficient to fund our operations for the next twelve months with a current burn rate of approximately $1 million per month. These conditions raise substantial doubt as to Opexa’s ability to continue as a going concern. Management will seek to raise additional capital through sales of convertible debt and/or equity. The financial statements do not include any adjustments that might be necessary if Opexa is unable to continue as a going concern.

NOTE 3—RESTATEMENT OF FINANCIAL STATEMENTS

The Company is restating these financial statements for the three months and nine months ended September 30, 2006 and 2007 and the period January 22, 2003 (Inception) to September 30, 2007.

Following is a description of the restatements:

The Company acquired Opexa Pharmaceuticals in October 2004 and originally accounted for the acquired in process research and development of $23,991,128 as intangible assets. In November 2007 the Company re-evaluated its accounting for acquired research and development and upon further consideration of Paragraph 11(c) of Statement of Financial Accounting Standards No. 2 (SFAS No. 2) and accounting guidance from Financial Accounting Standards Board Interpretation No. 4 “Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method” (FIN 4), the Company determined that these assets did not have an alternative future use at the date of acquisition. Thus, they had no separate economic value and should be accordingly expensed to research and development in the period acquired.

In February 2004, the Company obtained a license from the University of Chicago for an adult stem cell technology. Costs associated with the acquisition of this license were originally accounted for as an intangible asset. The amounts originally capitalized as intangible assets were $3,051,706, $976,497 and $112,440 for the years ended December 31, 2004, 2005 and 2006 respectively. Upon further consideration of Paragraph 11(c) of SFAS No. 2, the Company determined that these assets had not reached technological feasibility at the date of acquisition and had no alternative future use. Therefore, the intangible asset should have been expensed to in process research and development in the period acquired.

In March 2006, the Company obtained an exclusive worldwide license for the intellectual property rights and research results of an autologous T cell vaccine for rheumatoid arthritis from the Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences of the People’s Republic of China. The Company made a $125,000 license payment and accounted for the license as an intangible asset. Upon further consideration of Paragraph 11(c) of SFAS No. 2, the Company determined that this asset had not reached technological feasibility at the date of acquisition and had no alternative future use. Therefore, the intangible asset should have been expensed to in process research and development in the period acquired.

NOTE 4—CASH AND CASH EQUIVALENTS

Opexa considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Investments with maturities in excess of three months but less than one year are classified as short-term investments and are stated at fair market value.

The primary objectives for our fixed income investment portfolio are liquidity and safety of principal. Investments are made with the objective of achieving the highest rate of return consistent with these two objectives. Opexa’s investment policy limits investments to certain types of instruments issued by institutions primarily with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer.

At September 30, 2007, Opexa invested approximately $4.0 million in A-1/P-1 commercial paper with an average market yield of 5.24% and average time to maturity of less than one month. At September 30, 2007, approximately $1.9 million was invested in a money market account with an average yield of 5.29%. Interest income of $423,086 was recognized for the nine months ended September 30, 2007 in the statement of expenses.

NOTE 5—COMMITMENTS AND CONTINGENCIES

In September 2006, Opexa entered into an Individual Project Agreement (IPA) with PharmaNet, LLC, a contract research organization focused on managing central nervous system trials. Pursuant to such IPA, PharmaNet, LLC will provide Opexa with services in connection with its Phase IIb clinical trial. Under the terms of the IPA, Opexa is required to advance funds in the amount of (i) $400,000 for professional fees, (ii) $60,000 for out of pocket expenses and (iii) $175,000 for investigator grants. The professional fee advance is applied 1/12th per month to invoices and replenished once 75% depleted. The out of pocket advance will be held and applied to the final invoice. The investigator grant advance is used as a draw down advance and replenished once 75% depleted. This process will continue until the end of the study. At the conclusion of the program, advance balances remaining will be applied to outstanding invoices. These advances are treated as prepaid items and included in the other current assets section of the balance sheet. As of September 30, 2007, the advance balance to PharmaNet, LLC was $293,336.

In July 2007, Opexa entered into a seconded amended and restated license agreement with the University of Chicago that requires Opexa to make milestone payments of up to $1,350,000 if certain late stage clinical trial and FDA approval milestones are achieved. Opexa has determined that these payments are not probable at this time and thus no liability has been recorded as of September 30, 2007.

NOTE 8—DERIVATIVE INSTRUMENTS

In June 2006, Opexa evaluated the application of SFAS 133 and EITF 00-19 for all of its financial instruments and it was determined that certain of the warrants to purchase common stock issued by Opexa associated with the bridge note exchange and private placement offerings in June 2005 and July 2005 were derivatives that Opexa was required to account for as free-standing derivative instruments under GAAP. These three series of warrants were considered at the time to be derivatives because the liquidated damage provision in the registration rights agreement covering each warrant resulted in the conclusion that it was more economic to issue registered shares than to issue unregistered shares and pay the penalty. Because issuing registered shares is outside of Opexa’s control, Opexa concluded the warrants should be accounted for as derivative liabilities under SFAS 133 and EITF 00-19. As a result, Opexa reported the value of these derivatives as current liabilities on its balance sheet and reported changes in the value of these derivatives as non-operating gains or losses on its statements of operations in the consolidated financial statements beginning with the year ended December 31, 2005 and re-measured and reported on a quarterly basis thereafter based on the Black Scholes Pricing Model.

In December 2006, the FASB issued FASB Staff Position No. EITF 00-19-2, Accounting for Registration Payment Arrangements (EITF 00-19-2). EITF 00-19-2 addresses an issuer’s accounting for registration payment arrangements. It specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. The guidance in EITF 00-19-2 amends FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and FASB Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, including Indirect Guarantees of Indebtedness of Others, to include scope exceptions for registration payment arrangements. EITF 00-19-2 also requires additional disclosure regarding the nature of any registration payment arrangements, alternative settlement methods, the maximum potential amount of consideration and the current carrying amount of the liability, if any. This EITF is effective immediately for registration payment arrangements and the financial instruments subject to those arrangements that are entered into or modified subsequent to the date of issue of this EITF. For registration payment arrangements and financial instruments subject to those arrangements that were

entered into prior to the issuance of this EITF, this is effective for financial statements issued for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years.

Opexa evaluated the application of EITF 00-19-2 for all its financial instruments and determined that certain warrants to purchase common stock issued by Opexa associated with the bridge note exchange and private placement offerings in June 2005 and July 2005 no longer qualified to be classified as derivative liabilities. In addition, Opexa accounts for registration rights agreement penalties as contingent liabilities, applying the accounting guidance of Financial Accounting Standard No. 5, “Accounting for Contingencies” (“FAS 5”). This accounting is consistent with views established by the FASB Staff Positions FSP EITF 00-19-2 “Accounting for Registration Payment Arrangements”, which was issued December 21, 2006. Accordingly, Opexa recognizes the damages when it becomes probable that they will be incurred and amounts are reasonably estimable.

4,600,000 shares of common stock and 2,513,720 warrants to purchase common stock are subject to a registration payment arrangement that provides if a resale registration statement is not effective for any period after April 13, 2007, the warrant holders may exercise their warrants on a cashless basis during the period the resale registration statement is not effective. If Opexa fails to register, achieve effectiveness of registration or maintain effectiveness of registration of shares underlying the warrants and shares, they are required to make certain liquidated damage payments of 1.5% of the aggregate amount of proceeds of the offering per month for every month in default with a maximum of 24%. Opexa does not believe these payments are probable and thus no contingent liability has been recorded.

1,272,356 shares of common stock and 1,714,410 shares of common stock issuable upon the exercise of common stock purchase warrants issued in June 2005 and July 2005 are subject to a registration payment arrangement that provides if a resale registration statement is not effective for any period after the first anniversary of the warrant, the warrant holders may exercise their warrants on a cashless basis during the period the resale registration statement is not effective. If Opexa fails to register, achieve effectiveness of registration or maintain effectiveness of registration of shares underlying the warrants and shares, they are required to make certain liquidated damage payments of 1.0% of the aggregate amount of proceeds of the offering per month for the first calendar month of registration default and 2% for every month in default after the first month. Opexa does not believe these payments are probable and thus no contingent liability has been recorded.

The impact of implementing EITF 00-19-2 for the nine months ended September 30, 2007 resulted in a cumulative effect of a change in accounting principle with a decrease in the derivative liability of $6,656,677 and a decrease to beginning retained earnings of $4,001,819 reversing gains posted to date and a reclassification of the original value of the warrants from liability to equity of $10,658,496.

NOTE 9—LICENSES AND GAIN ON EXTINGUISHMENT OF DEBT

University of Chicago License Agreement

In 2004, Opexa entered into an agreement with the University of Chicago (“University”) for the worldwide license to technology developed at Argonne National Laboratory, a U.S. Department of Energy Laboratory operated by the University. The license was later amended granting Opexa an exclusive, non-transferable worldwide license to the University’s stem cell technology. In consideration for the license and amendment, Opexa paid the University a total of $232,742 and issued the University 53,462 shares of common stock valued at $2,295,461. Opexa also agreed to pay the University $1.5 million and to issue the University 21,623 shares of Opexa common stock. In April 2007, the $1.5 million cash payment obligation was extended until July 31, 2007 and the obligation to issue shares of Opexa’s common stock was extended until July 31, 2007, with $112,440 accrued as of June 30, 2007. The Company determined that these assets had not reached technological feasibility at the date of acquisition and had no alternative future use. Therefore, the costs were expensed to research and development in the period incurred.

On July 31, 2007, Opexa entered into a second amended and restated license agreement with the University of Chicago that eliminated the obligations under the prior agreement for the payment of $1.5 million due July 31, 2007 and the obligation to issue 21,623 shares of Opexa common stock. These obligations were recorded as an intangible asset, with the liabilities recorded as a notes payable—current portion of $1.5 million and a stock payable of $112,440. As a result of the amendment and restatement of the license agreement with the University of Chicago $1,612,440 was reported as a gain on extinguishment of liability. Opexa applied the accounting guidance of Financial Accounting Standard No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities” (“FAS 140”) and EITF 96-19 “Debtor’s Accounting for a Modification or Exchange of Debt Instruments”.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24. Indemnification of Directors and Officers.

Opexa Therapeutics, Inc. (the “Company”) has the authority under Articles 2.02a(16) and 2.02-1 of the Texas Business Corporation Act (“TBCA”) to indemnify its directors and officers to the extent provided for in such statute. The TBCA provides, in part, that a corporation may indemnify a director or officer or other person who was, is or is threatened to be made a named defendant or respondent in a proceeding because such person is or was a director, officer, employee or agent of the corporation, if it is determined that such person: (1) conducted himself in good faith; (2) reasonably believed, in the case of conduct in his official capacity as a director or officer of the corporation, that his conduct was in the corporation’s best interest and, in all other cases, that his conduct was at least not opposed to the corporation’s best interests; and (3) in the case of any criminal proceeding, had no reasonable cause to believe that his conduct was unlawful.

A corporation may indemnify a person under the TBCA against judgments, penalties, including excise and similar taxes, fines, settlement, unreasonable expenses actually incurred by the person in connection with the proceeding. If the person is found liable to the corporation or is found liable on the basis that personal benefit was improperly received by the person, the indemnification is limited to reasonable expenses actually incurred by the person in connection with the proceeding, and shall not be made in respect of any proceeding in which the person shall have been found liable for willful or intentional misconduct in the performance of his duty to the corporation. The corporation may also pay or reimburse expenses incurred by a person in connection with his appearance as a witness or other participation in a proceeding at a time when he is not a named defendant or respondent in the proceeding.

The Company’s Articles of Incorporation provide that none of its directors shall be personally liable to the Company or its shareholders for monetary damages for an act or omission in such director’s capacity as a director; provided, however, that the liability of such director is not limited to the extent that such director is found liable for (1) a breach of the director’s duty of loyalty to the Company or its shareholders, (2) an act or omission not in good faith that constitutes a breach of duty of the director to the Company or an act or omission that involves intentional misconduct or a knowing violation of the law, (3) a transaction from which the director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director’s office, or (4) an act or omission for which the liability of the director is expressly provided by an applicable statute.

The Company believes that these provisions will assist it in attracting and retaining qualified individuals to serve as executive officers and directors. The inclusion of these provisions in the Company’s Articles of Incorporation may have the effect of reducing the likelihood of derivative litigation against the Company’s directors and may discourage or deter shareholders or management from bringing a lawsuit against directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefited us or our shareholders.

The Company’s Articles of Incorporation and By-laws provide that the Company may indemnify its officers, directors, agents and any other persons to the fullest extent permitted by the TBCA.

Additionally, under their employment agreements with Opexa Therapeutics Inc. Mr. McWilliams, Dr. Williams, Ms. Hohlfeld and Ms. Rill are entitled to indemnification in their capacity as officers of the Company to the fullest extent permitted by the TBCA.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

 

II-5


Table of Contents
Index to Financial Statements

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represents a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
