|   | • | Annualized relapse rate (ARR) for Tovaxin-treated patients was 0.214 as compared to 0.339 for placebo-treated patients, which represented a 37% decrease in ARR for Tovaxin as compared to placebo in the general population. |
|--------|---------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | • | For patients who had more active disease as indicated by a prospective subgroup of patients with an ARR>1 in the year prior to the study, Tovaxin demonstrated a 55% reduction in ARR as compared to placebo; and an 87% reduction in relapse rate was observed in Tovaxin patients in this population compared to placebo during the 24 week period following the administration of the full course of treatment (p=0.039). |
|--------|---------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | • | Patients who had an ARR>1 at study entry demonstrated a statistically significant improvement in disability score as measured by the Expanded Disability Status Scale (EDSS) (p =0.045) for patients treated with Tovaxin as compared to those receiving placebo. The EDSS score is a measure of disability ranging from 0-10. In addition, 28.1% of the Tovaxin patients showed an improvement in EDSS of at least one point as compared to 5.6% in the placebo group. |
|--------|---------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | • | Patients who had an ARR>1 at study entry and were treated with Tovaxin experienced an 88% reduction in brain atrophy and a 59% reduction in absolute T-2 lesion volume as compared to placebo. |
|--------|---------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | • | Tovaxin was safe and well tolerated with no serious adverse events related to Tovaxin treatment. The most common adverse event was injection site irritation which was generally mild and transient. |

Item 1.  Legal Proceedings.

Item 1A.  Risk Factors.

| ·   | Our business is at an early stage of development. We are largely dependent on the success of our lead product candidate, Tovaxin, and we cannot be certain that Tovaxin will receive regulatory approval or be successfully commercialized. |
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

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

| ·   | Our ability to obtain necessary funding is uncertain. |
|--------------------|-------------------------------------------------------|

| ·   | Our independent auditor’s report in respect of our 2008 fiscal year expressed substantial doubt about our ability to continue as a going concern, which may make raising capital more difficult. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We will depend on strategic collaborations with third parties to develop and commercialize product candidates, such as Tovaxin, and we may not have control over a number of key elements relating to the development and commercialization of any such product candidate. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We will need regulatory approvals for any product candidate, including Tovaxin, prior to introduction to the market, which will require successful testing in clinical trials. Clinical trials are subject to extensive regulatory requirements, and are very expensive, time-consuming and difficult to design and implement. Any product candidate, such as Tovaxin, may fail to achieve necessary safety and efficacy endpoints during clinical trials in which case we will be unable to generate revenue from the commercialization and sale of our products. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We will rely on third parties to conduct our clinical trials and perform data collection and analysis, which may result in costs and delays that may hamper our ability to successfully develop and commercialize any product candidate, including Tovaxin. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | If we fail to identify and license or acquire other product candidates, we will not be able to expand our business over the long term. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------|

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

| ·   | 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 current research and manufacturing facility is not large enough to manufacture product candidates, such as Tovaxin, for clinical trials or, if such clinical trials are successful, commercial applications. |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | If any product we may eventually have is not accepted by the market or if users of any such product are unable to obtain adequate coverage of and reimbursement for such product from government and other third-party payors, our revenues and profitability will suffer. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| ·   | Any product candidate that we develop, such as Tovaxin, if approved for sale, may not gain acceptance among physicians, patients and the medical community, thereby limiting our potential to generate revenues. |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We have incurred, and expect to continue to incur, increased costs and risks as a result of being a public company. |
|--------------------|---------------------------------------------------------------------------------------------------------------------|

| ·   | 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, such as Tovaxin. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | If we are unable to obtain patent protection and other proprietary rights, our operations will be significantly harmed. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------|

| ·   | Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and other proprietary information and may not adequately protect our intellectual property, which could limit our ability to compete. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | A dispute concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time consuming and costly, and an unfavorable outcome could harm our business. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We are subject to stringent regulation of our product candidates, such as Tovaxin, which could delay development and commercialization. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------|

| ·   | We may need to change our business practices to comply with health care fraud and abuse regulations, and our failure to comply with such laws could adversely affect our business, financial condition and results of operations. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | If our competitors develop and market products that are more effective than our product candidates, they may reduce or eliminate our commercial opportunities. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Rapid technological change could make our products obsolete. |
|--------------------|--------------------------------------------------------------|

| ·   | Consumers may sue us for product liability, which could result in substantial liabilities that exceed our available resources and damage our reputation. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Health care reform measures could adversely affect our business. |
|--------------------|------------------------------------------------------------------|

| ·   | There is currently a limited market for our securities, and any trading market that exists in our securities may be highly illiquid and may not reflect the underlying value of our net assets or business prospects. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Our stock may be delisted from NASDAQ, which could affect its market price and liquidity. |
|--------------------|-------------------------------------------------------------------------------------------|

| ·   | As our share price is volatile, and you may not be able to resell our shares at a profit or at all. |
|--------------------|-----------------------------------------------------------------------------------------------------|

| ·   | We may be or become the target of securities litigation, which is costly and time-consuming to defend. |
|--------------------|--------------------------------------------------------------------------------------------------------|

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

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

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

| ·   | Our stockholders may experience substantial dilution in the value of their investment if we issue additional shares of our capital stock. |
