During the six months ended June 30, 2020, the Company had not generated any revenues, had a net loss of approximately $1,978,000 and had used cash in operations of approximately $1,154,000. As of June 30, 2020, the Company had a working capital deficiency of approximately $6,528,000 and an accumulated deficit of approximately $23,124,000. Subsequent to June 30, 2020 and as more fully described in Note 10, Subsequent Events, the Company received proceeds of $603,355 through the sale of 80,466 shares of Series A Convertible Preferred Stock at $7.50 per share and net proceeds of $497,500 through the issuance of a convertible note payable in the principal amount of $555,556. These conditions raise substantial doubt about the Company's ability to continue as a going concern within twelve months from the date these financial statements are issued.

The Company is currently funding its operations on a month-to-month basis. While there can be no assurance that it will be successful, the Company is in active negotiations to raise additional capital. The Company's primary sources of operating funds since inception have been equity and debt financings. Management's plans include continued efforts to raise additional capital through debt and equity financings. There is no assurance that these funds will be sufficient to enable the Company to fully complete its development activities or attain profitable operations. If the Company is unable to obtain such additional financing on a timely basis or, notwithstanding any request the Company may make, if the Company's debt holders do not agree to convert their notes into equity or extend the maturity dates of their notes, the Company may have to curtail its development, marketing and promotional activities, which would have a material adverse effect on the Company's business, financial condition and results of operations, and ultimately the Company could be forced to discontinue its operations and liquidate.

The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the financial statements do not necessarily purport to represent realizable or settlement values. The condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.

Note 3 - Summary of Significant Accounting Policies

Since the date of the Annual Report on Form 10-K for the year ended December 31, 2019, there have been no material changes to the Company's significant accounting policies.





Loss Per Share


The Company computes basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities. Diluted earnings per share includes the dilution that would occur upon the exercise or conversion of all dilutive securities into common stock using the "treasury stock" and/or "if converted" methods, as applicable. Weighted average shares outstanding for the three and six months ended June 30, 2020 and 2019 includes the weighted average impact of warrants to purchase an aggregate of 2,043,835 shares of common stock because their exercise price was determined to be nominal.

The common stock equivalents associated with the following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:





                                         June 30,
                                  2020             2019

Options                          3,782,004                -
Warrants                         5,744,477        6,409,157
Convertible notes                3,258,424        1,073,921
Convertible preferred stock     12,617,490       11,554,260
Total                           25,402,395       19,037,338



Convertible notes are assumed to be converted at the rate of $0.75 per common share, which is the conversion price. However, such conversion rates are subject to adjustment under certain circumstances, which may result in the issuance of common shares greater than the amount indicated.





Reclassifications


Certain prior period amounts have been reclassified in order to conform to the fiscal 2020 presentation, including certain accrued liabilities that have been reclassified from accrued compensation to accrued interest as well as certain operating expenses that have been reclassified to other expenses. These reclassifications have no impact on the previously reported net loss.





Note 4 - Fair Value


During the six months ended June 30, 2020, in connection with the extension of certain convertible notes payable that previously contained a variable conversion price with no floor and, a result, triggered sequencing, the parties agreed to amend the conversion terms such that a conversion price floor of $0.75 per share was established. As a result, the Company had no remaining outstanding instruments with a variable conversion price with no floor and, accordingly, the Company reclassified derivative liabilities with an aggregate fair value of $345,830 to additional paid-in capital. See Note 6, Notes Payable and Convertible Notes Payable for additional details.

Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. As of June 30, 2020, the Company's Level 3 liabilities shown in the above table consist of accrued obligations to issue warrants and common stock. As of December 31, 2019, the Company's Level 3 liabilities shown in the above table consist of sequenced warrants with no price floor as the Company was unable to determine that it had sufficient authorized common stock to settle such arrangements, warrants deemed to be derivative liabilities according to the Company's sequencing policy in accordance with ASC 815-40-35-12, the embedded conversion options within its convertible notes payable and an accrued obligation to issue warrants and common stock.

In applying the Black-Scholes option pricing model utilized in the valuation of Level 3 liabilities, the Company used the following approximate assumptions:

The expected term used is the contractual life of the instrument being valued. Since the Company's stock does not have significant trading volume, the Company is utilizing an expected volatility based on a review of the historical volatilities, over a period of time, equivalent to the expected life of the instrument being valued, of similarly positioned public companies within its industry. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.

Litigation


Certain conditions may exist as of the date the condensed consolidated financial statements are issued, which may result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur. The Company assesses such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company, or unasserted claims that may result in such proceedings, the Company evaluates the perceived merits of any legal proceedings or unasserted claims, as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Company's consolidated financial statements. If the assessment indicates that a potential material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability and an estimate of the range of possible losses, if determinable and material, would be disclosed.

In January 2019, the holder of a promissory note in the principal amount of $250,000 due on March 16, 2016 instituted a collection action in the Supreme Court of the State of New York, County of New York. A motion for summary judgement was heard on March 7, 2019 and the Company did not oppose the motion. The Company has had discussion with respect to entering into an agreement providing for a payment plan with the holder of the note, but no agreement has yet been reached.

Loss contingencies considered remote are generally not disclosed, unless they involve guarantees, in which case the guarantees would be disclosed. There can be no assurance that such matters will not materially and adversely affect the Company's business, financial position, and results of operations or cash flows. As of June 30, 2020 and December 31, 2019, the Company has not accrued any amounts for contingencies.





Note 10 - Subsequent Events



The Company has evaluated events that have occurred after the balance sheet and through the date the financial statements were issued. Based upon the evaluation, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements, except as disclosed below.

Series A Convertible Preferred Stock

Subsequent to June 30, 2020, the Company received proceeds of $603,355 through the sale of 80,446 shares of Series A Convertible Preferred Stock at $7.50 per share, such that the Company's PPM was now fully subscribed.





Convertible Notes Payable


On July 6, 2020, the Company repaid a convertible note in full, which payment included a prepayment penalty, for an aggregate total payment of $115,483 (principal and interest of $78,000 and $37,483, respectively). See Note 6, Notes Payable and Convertible Notes Payable - Convertible Notes Payable for additional details associated with the repayment of this convertible note.

On July 29, 2020, the Company issued a convertible note payable in the principal amount of $555,556 for net proceeds of $497,500 (gross proceeds of $500,000 less $2,500 of issuance costs) which matures on January 29, 2021. The note accrues interest at 13% per annum and is convertible into common stock at the lower of (i) a conversion price of $0.75 per share (the "Fixed Conversion Price") or (ii) in the event of a default, as defined in the note, a conversion price of 65% of the lowest volume weighted average price for the ten consecutive trading days ending on the trading day that is immediately prior to the applicable conversion date (the "Default Conversion Price"). The Default Conversion Price shall not apply before March 29, 2021. So long as the convertible note is outstanding, upon any issuance by the Company of any equity at an effective price lower than the conversion price (the "Base Conversion Price"), then the conversion price shall be reduced to equal such Base Conversion Price. In connection to the issuance of the convertible note payable, the Company issued a five-year immediately vested warrant to purchase 146,199 shares of common stock at an exercise price of $0.95 per share, which may be exercised on a cashless basis.





Notes Payable


On July 29, 2020, the Company fully repaid the principal of a promissory note in the amount of $100,000. See Note 6, Notes Payable and Convertible Notes Payable - Notes Payable for additional details associated with the repayment of this note.

Overview


We are a cell therapy company focused on immunotherapy. Since our inception, we have been involved with the development of proprietary immune system management technology licensed from Yeda Research & Development Company Limited ("Yeda"), the commercial arm of the Weizmann Institute of Science. We have recently shifted the focus of our Research and Development efforts to MD Anderson.

This technology addresses one of the most fundamental challenges within human immunology: how to tune the immune response such that it tolerates selected desirable foreign cells or tissue, but continues to attack all other (undesirable) targets. In simpler terms, a number of potentially life-saving treatments have limited effectiveness today because the patient's immune system rejects them. For example, while HSCT - hematopoietic stem cell transplantation (e.g. bone marrow transplantation) has become a preferred therapeutic approach for treating blood cell cancer, most patients do not have a matched family donor. Although matched unrelated donors and cord blood can each provide an option for such patients, haploidentical stem cell transplants (sourced from partially mismatched family members) are rapidly gaining favor as a treatment of choice. This is still a risky and difficult procedure primarily because of potential conflicts between host and donor immune systems and also due to viral infections that often follow even successful HSCT while the compromised new immune system works to reconstitute itself by using the transplanted stem cells. Today, rejection is partially overcome using aggressive immune suppression treatments that leave the patient exposed to many dangers by compromising their immune system.

The unique advantage of Cell Source technology lies in the ability to induce sustained tolerance of transplanted cells (or organs) by the recipient's immune system in a setting that requires only mild immune suppression, while avoiding the most common post-transplant complications. The scientific term for inducing such tolerance in a transplantation setting is chimerism, where the recipient's immune system tolerates the co-existence of the (genetically different) donor type and host (recipient) type cells. Attaining sustained chimerism is an important prerequisite to achieving the intrinsic GvL (graft versus leukemia) effect of HSCT and supporting the reconstitution of normal hematopoiesis (generation of blood cells, including those that protect healthy patients from cancer) in blood cancer patients. Preclinical data show that Cell Source's Veto Cell technology (currently in clinical trials in the US) can provide superior results in allogeneic (donor-derived) HSCT by allowing for haploidentical stem cell transplants under a mild conditioning regimen, while avoiding the most common post-transplant complications. Combining this with CAR (Chimeric Antigen Receptor) T cell therapy as a unified VETO CAR-T treatment, we will be able to treat patients in relapse as well as those in remission and use the cancer killing power of CAR-T to protect the patient while their immune system fully reconstitutes, thus providing an end-to-end solution for blood cancer treatment by potentially delivering a fundamentally safer and more effective allogeneic HSCT: prevention of relapse; avoidance of GvHD; prevention of viral infections; and enhanced persistence of GvL effect. This means that the majority of patients will be able to find a donor, and will have access to a potentially safer procedure with higher long term survival rates than what either donor-derived HSCT or autologous CAR-T each on their own currently provide.

  Table of Contents



The ability to induce permanent chimerism (and thus sustained tolerance) in patients - which allows the transplantation to overcome rejection without having to compromise the rest of the immune system - may open the door to effective treatment of a number of severe medical conditions, in addition to blood cancers, which are characterized by this need. These include:





    ·   The broader set of cancers, including solid tumors, that can potentially
        be treated effectively using genetically modified cells such as CAR-T cell
        therapy, but also face efficacy and economic constraints due to limited
        persistence based on immune system issues (i.e., the need to be able to
        safely and efficiently deliver allogeneic CAR-T therapy). Inducing
        sustained tolerance to CAR-T cells may bring reduced cost and increased
        efficacy by allowing for off-the-shelf (vs. patient-derived) treatments
        with more persistent cancer killing capability.

    ·   Organ failure and transplantation. A variety of conditions can be treated
        by the transplantation of vital organs. However, transplantation is
        limited both by the insufficient supply of available donor organs and the
        need for lifelong, daily anti-rejection treatments post-transplant.
        Haploidentical organ transplants, with sustained chimerism, have the
        potential to make life saving transplants accessible to the majority of
        patients, with the prospect of improved life quality and expectancy.

    ·   Non-malignant hematological conditions (such as type one diabetes and
        sickle cell anemia) which could, in many cases, also be more effectively
        treated by stem cell transplantation if the procedure could be made safer
        and more accessible by inducing sustained tolerance in the stem cell
        transplant recipient.




Recent Developments



COVID-19


Recently, the outbreak of the novel coronavirus, or COVID-19, around the world has adversely impacted global commercial activity and contributed to significant volatility in financial markets and disrupted normal business operations. The global impact of the outbreak has been rapidly evolving, and many countries have reacted by instituting quarantines and restrictions on travel, and many businesses and other institutions have temporarily closed or reduced work activities at their facilities. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as transportation, hospitality and entertainment. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of the novel coronavirus. Nevertheless, the novel coronavirus presents material uncertainty and its disruption of the capital markets may have a material adverse impact on our ability to raise additional capital and may slow down the pace at which research and clinical trials may be conducted on our behalf.





Convertible Notes Payable


On June 18, 2020, the Company received proceeds of $500,000 through a previously issued convertible note dated October 28, 2019 in the principal amount of $1,500,000, such that the Company had now received aggregate proceeds of $1,500,000 under the convertible note. The convertible note has a maturity date of October 31, 2020. In connection with the receipt of these proceeds, the Company issued a five-year immediately vested warrant for the purchase of 1,200,000 shares of common stock at an exercise price of $1.25 per share.

On July 29, 2020, the Company issued a convertible note payable in the principal amount of $555,556 for net proceeds of $497,500 (gross proceeds of $500,000 less $2,500 of issuance costs) which matures on January 29, 2021. The note accrues interest at 13% per annum and is convertible into common stock at the lower of (i) a conversion price of $0.75 per share (the "Fixed Conversion Price") or (ii) in the event of a default, as defined in the note, a conversion price of 65% of the lowest volume weighted average price for the ten consecutive trading days ending on the trading day that is immediately prior to the applicable conversion date (the "Default Conversion Price"). The Default Conversion Price shall not apply before March 29, 2021. So long as the convertible note is outstanding, upon any issuance by the Company of any equity at an effective price lower than the conversion price (the "Base Conversion Price"), then the conversion price shall be reduced to equal such Base Conversion Price. In connection to the issuance of the convertible note payable, the Company issued a five-year immediately vested warrant to purchase 146,199 shares of common stock at an exercise price of $0.95 per share, which may be exercised on a cashless basis.

Liquidity and Going Concern

We measure our liquidity in a number of ways, including the following:





                               June 30,       December 31,
                                 2020             2019
                             (unaudited)

Cash                         $      1,113     $      27,908

Working capital deficiency $ (6,528,017 ) $ (5,596,941 )

During the six months ended June 30, 2020, we had not generated any revenues, had a net loss of approximately $1,978,000 and had used cash in operations of approximately $1,154,000. As of June 30, 2020, we had a working capital deficiency of approximately $6,528,000 and an accumulated deficit of approximately $23,124,000. Subsequent to June 30, 2020, we received proceeds of $603,355 through the sale of 80,446 shares of Series A Convertible Preferred Stock at $7.50 per share and net proceeds of $497,500 through the issuance of a convertible note payable in the principal amount of $555,556. These conditions raise substantial doubt about our ability to continue as a going concern within twelve months from the date these financial statements are issued.

We are currently funding its operations on a month-to-month basis. Our ability to continue our operations is dependent on the execution of management's plans, which include the raising of capital through the debt and/or equity markets, until such time that funds provided by operations are sufficient to fund working capital requirements. We may need to incur additional liabilities with certain related parties to sustain our existence. If we were not to continue as a going concern, we would likely not be able to realize our assets at values comparable to the carrying value or the fair value estimates reflected in the balances set out in the preparation of our financial statements.

There can be no assurances that we will be successful in generating additional cash from equity or debt financings or other sources to be used for operations. Should we not be successful in obtaining the necessary financing to fund our operations, we would need to curtail certain or all operational activities and/or contemplate the sale of our assets, if necessary.

During the six months ended June 30, 2020 and 2019, our sources and uses of cash were as follows:






         19

  Table of Contents



Net Cash Used in Operating Activities

We experienced negative cash flows from operating activities for the six months ended June 30, 2020 and 2019 in the amounts of approximately $1,154,000 and $1,186,000, respectively. The net cash used in operating activities for the six months ended June 30, 2020 was primarily due to cash used to fund a net loss of approximately $1,978,000, adjusted for net non-cash expenses in the aggregate amount of approximately $516,000, partially offset by $308,000 of net cash provided by changes in the levels of operating assets and liabilities. The net cash used in operating activities for the six months ended June 30, 2019 was primarily due to cash used to fund a net loss of approximately $2,411,000, adjusted for net non-cash expenses in the aggregate amount of approximately $434,000, partially offset by approximately $791,000 of net cash provided by changes in the levels of operating assets and liabilities.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2020 and 2019 was approximately $1,127,000 and $1,195,000, respectively. The net cash provided by financing activities during the six months ended June 30, 2020 was attributable to $1,075,000 of proceeds from the issuance of convertible notes payable, $125,000 of proceeds from the issuance of Series A preferred stock, $100,000 of proceeds from the issuance of notes payable and $100,000 of proceeds from advances payable, offset by the repayment of a note payable in the amount of $100,000, $105,000 of repayments of advances payable and a $68,000 repayment of a convertible note payable. The net cash provided by financing activities during the six months ended June 30, 2019 was attributable to approximately $1,123,000 of proceeds received from the issuance of Series A preferred stock and $72,000 of net proceeds from debt financings.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.
