PHIO PHARMACEUTICALS CORP.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. Nature of Operations

Phio Pharmaceuticals Corp. (“Phio,” “we,” “our” or the “Company”) is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (“INTASYL™”) therapeutic platform. The ~~Company's~~Company’s efforts are focused on silencing tumor-induced suppression of the immune system through its proprietary INTASYL platform with utility in immune cells and the tumor micro-environment. The Company’s goal is to develop powerful INTASYL therapeutic compounds that can weaponize immune effector cells to overcome tumor immune escape, thereby potentially providing patients with a powerful new treatment option that goes beyond current treatment modalities.
In December 2019, a novel strain of coronavirus that causes COVID-19 was reported to have surfaced in Wuhan, China and has since spread to other parts of the world, including the United States. In March 2020, the World Health Organization (the “WHO”) declared the outbreak a pandemic. Our operations have continued with limited impact and are operating in accordance with federal, state, the WHO and the Center for Disease Control’s guidelines, including the implementation of safety measures such as working remotely, staggered scheduling and cleaning protocols. While the measures to contain and prevent the spread of coronavirus may be modified or extended, we expect that our activities, including our internal research and development functions, will continue to remain largely operational.
As a result of the coronavirus pandemic, certain of our third-party suppliers and service providers on which we rely have seen impacts to their operations and if the impact to their operations continue or extend, it may in turn affect our operations. The Company has undertaken efforts to mitigate potential future impact by identifying and engaging alternative third-party service providers and suppliers, and because of that, to date the Company has not seen a material impact to its program’s anticipated timelines resulting from delays from our third-party service providers. For example, by engaging different contract manufacturers, the Company believes that it has a sufficient supply of its INTASYL compounds to conduct its ongoing preclinical studies and initial clinical activities. However, the ultimate impact to these third parties on which we rely is highly uncertain and subject to change. Without a swift and sustained improvement of the impacts experienced by the Company’s third-party suppliers and service providers, the effect of our mitigation efforts will diminish and may result in material impacts to our operations. If the global measures to contain the pandemic are insufficient, it could reduce or delay the availability of supplies and services that we purchase and rely, which may in turn slow or delay our preclinical and clinical activities, and/or result in higher costs.
We believe that the coronavirus pandemic has not had a significant impact on our financial condition thus far, however a variety of factors such as those described above, including current and future restrictions and the length of the pandemic, may further impact our operations and may slow or diminish our research and development activities, which in turn may impact our financial condition. The extent to which the coronavirus pandemic impacts our results will depend on future developments, which are highly uncertain and cannot be predicted.

2. Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures included in the Company’s annual financial statements have been condensed or omitted. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation of the condensed consolidated financial statements have been included. Interim results are not necessarily indicative of results for a full year.
~~Reverse Stock Split~~
Effective January 15, 2020, the Company completed a 1-for-55 reverse stock split of the Company’s outstanding common stock. All share and per share amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in capital. Unless otherwise noted, shares of common stock issued and outstanding, shares underlying warrants and stock awards, shares reserved, conversion price of convertible securities, exercise prices of warrants and stock awards and loss per share have been proportionately adjusted to reflect the reverse stock split. The reverse stock split did not reduce the number of authorized shares of the Company’s common stock or preferred stock.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Phio and its wholly-owned subsidiary, MirImmune, LLC. All material intercompany accounts have been eliminated in consolidation.

~~Risks and Uncertainties~~
In December 2019, a novel strain of coronavirus, causing COVID-19, was reported to have surfaced in Wuhan, China and has since spread to other parts of the world, including the United States. In March 2020, the World Health Organization declared the outbreak a pandemic. We have not yet experienced any significant impacts or interruptions to our financial condition or operations as a result of the coronavirus pandemic at this time, but have begun to see impacts and delays with third party service providers that are presumably related to the pandemic. Without a sustained improvement of the current situation, we may experience significant and longer lasting impacts to certain of our development activities outsourced to third-party service providers beginning in the second half of 2020. If the measures to contain the outbreak continue or are extended, it may have a more significant effect on our operations and those of third parties on which we rely, including reducing the availability of supplies that we purchase, closures of or delays in businesses that we rely on to provide services and conduct preclinical and clinical activities for our product candidates and disrupting the supplies and services we rely on for the development of our product candidates. Additionally, a long lasting pandemic may adversely affect future clinical trial initiations and participant recruitment and enrollments, all of which may in turn slow, delay or pause our research and development activities. The ultimate impact of the coronavirus pandemic is highly uncertain and subject to change, and certain of our business operations may be delayed. The Company does not yet know the full extent of such potential delays or impacts on its business and preclinical and clinical trial activities. Moreover, the pandemic creates uncertainty around our ability to access capital markets and raise additional working capital that we will need to sustain our operations over the long term, particularly if the impacts of the pandemic are long lasting and affect us and our vendors and contractors.

7

~~Coronavirus Aid, Relief, and Economic Security Act~~
~~On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “~~~~CARES Act~~”) was enacted. The CARES Act is an emergency economic stimulus package passed in response to the coronavirus outbreak that includes, but is not limited to, provisions providing aid to small businesses in the form of loans and grants and numerous tax provisions such as certain payroll tax benefits, changes to the net operating loss rules, and the business interest expense deduction rules. On May 11, 2020, the Company received loan proceeds pursuant to the Paycheck Protection Program (the “~~PPP~~~~”) under the CARES Act.~~ ~~On June 5, 2020, President Trump signed into law the Paycheck Protection Program Flexibility Act of 2020 (the “~~~~Flexibility Act~~”), which amends the PPP created by the CARES Act. The Flexibility Act revises certain terms and provisions of the PPP to address issues raised by eligible borrowers adversely impacted by the ongoing COVID-19 pandemic. Refer to footnote 6 for further details. The Company does not expect the provisions outside of the PPP in the CARES Act to have a material impact on its condensed consolidated financial statements. As there continues to be updates to the implementation of the provisions under the CARES Act, the Company will continue to assess the potential impacts on our business, results of operations and financial statements.

Uses of Estimates in Preparation of Financial Statements

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The areas subject to significant estimates and judgement include, among others, those related to the fair value of equity awards, accruals for research and development expenses, ~~right of use lease assets, the fair value of financial instruments,~~ useful lives of property and equipment, income taxes, and our valuation allowance on our deferred tax assets. On an ongoing basis we evaluate our estimates and base our estimates on historical experience and other relevant assumptions that we believe are reasonable under the circumstances, including as a result of new information that may emerge concerning the coronavirus pandemic. We have made estimates of the impact of the coronavirus pandemic within our financial statements and there may be changes to those estimates in future periods. Actual results could differ materially from these estimates.

Restricted Cash

Restricted cash consists of certificates of deposit held by financial institutions as collateral for the Company’s corporate credit cards.

Fair Value of Financial Instruments
The carrying amounts reported in the balance sheet for restricted cash, accounts payable and accrued expenses approximate their fair values due to their short-term nature.
Leases

~~In connection with the adoption on January 1, 2019, the Company follows the provisions of the Financial Accounting Standards Board (the “~~~~FASB~~~~”) Accounting Standards Codification (“~~~~ASC~~~~”) Topic 842, “~~~~Leases~~~~” (“~~~~ASC 842~~~~”).~~ At the inception of a contract, the Company determines whether the contract is or contains a lease based on all relevant facts and circumstances. For contracts that contain a lease, the Company identifies the lease and non-lease components, determines the consideration in the contract and recognizes the classification of the lease as operating or financing. ~~At the commencement date of the lease,~~For leases with a term greater than one year, the Company recognizes a liability to make lease payments and an asset representing the right to use the underlying asset during the lease ~~term.~~
~~The Company has elected~~term at the ~~package~~commencement date of practical expedients to not reassess its prior conclusions about lease identification, lease classification and indirect costs and to not separate lease and non-lease components. The Company has elected not to recognize on the ~~balance sheet leases with a term less than one year.~~lease.

Lease liabilities and the corresponding right of use assets are recorded based on the present value of lease payments to be made over the lease term. The discount rate used to calculate the present value is the rate implicit in the lease, or if not readily determinable, the Company’s incremental borrowing rate. The Company’s incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right of use asset may be required for items such as initial direct costs or incentives received. Lease payments on operating leases are recognized on a straight-line basis over the expected term of the lease. Lease payments on financing leases are recognized using the effective interest method.

Debt
On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) in response to the coronavirus pandemic. The CARES Act is an emergency economic stimulus package passed in response to the coronavirus outbreak that includes, but is not limited to, provisions providing aid to small businesses in the form of loans and grants and numerous tax provisions such as certain payroll tax benefits, changes to the net operating loss rules, and the business interest expense deduction rules. On May 11, 2020, the Company received loan proceeds pursuant to the Paycheck Protection Program (the “PPP”) offered under the CARES Act. Outside of the PPP, the Company has not utilized the other loan programs and tax provisions, such as certain payroll tax benefits.
The Company followed the guidance under the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 470, “Debt” (“ASC 470”) in assessing the accounting for the PPP loan proceeds. Per ASC 470, the Company recorded a liability on the balance sheet for the full amount of PPP loan proceeds received and accrued interest over the term of the loan. Upon loan forgiveness, the Company recognized the extinguishment of the liability in the condensed consolidated statement of operations as a gain on extinguishment of debt.

Derivative Financial Instruments

~~The Company follows the provisions of the FASB ASC Topic 815, “~~~~Derivatives and Hedging~~~~” (“~~~~ASC 815~~~~”).~~ Financial instruments that meet the definition of a derivative are classified as an asset or liability and measured at fair value on the issuance date and are revalued on each subsequent balance sheet date. The changes in fair value are recognized as current period income or loss. Financial instruments that do not meet the definition of a derivative are classified as equity and measured at fair value and recorded as additional paid-in capital in stockholders’ equity at the date of issuance. No further adjustments to their valuation are made.
~~Fair Value of Financial Instruments~~
~~The carrying amounts reported in the balance sheet for restricted cash, prepaid expenses, accounts payable and accrued expenses approximate their fair values due to their short-term nature.~~

Research and Development Expenses

Research and development expenses relate to compensation and benefits for research and development personnel, facility-related expenses, supplies, external services, costs to acquire technology licenses, expenses associated with preclinical and clinical development activities and other operating costs. Research and development expenses are charged to expense as incurred. Payments made by the Company in advance for research and development services not yet provided and/or for materials not yet received are recorded as prepaid expenses and expensed when the service has been performed or when the goods have been received.
Accrued liabilities are recorded related to those expenses for which vendors have not yet billed the Company with respect to services provided and/or materials that it has received.
~~The Company contracts with third parties to perform various preclinical and clinical activities on its behalf~~ Accrued liabilities for the ~~continued development of its product candidates. Accruals and expenses~~services provided by contract research organizations (“CROs”) are recorded during the period incurred based on such estimates and assumptions as expected cost, passage of time, the achievement of milestones and other information available to us and are assessed on a quarterly basis. Actual results may differ from these estimates and could have a material impact on the Company’s reported results. The Company’s historical accrual estimates have not been materially different from its actual costs.

Stock-based Compensation

The Company follows the provisions of the FASB ASC Topic 718, “Compensation — Stock Compensation” (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based payment awards. The fair value of restricted stock units is based upon the Company’s closing stock price at the grant date. The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes valuation model requires the input of valuation assumptions to calculate the value of stock options, including expected volatility, expected term, risk-free interest rate and expected dividends. Stock-based compensation expense is ~~based on the grant date fair value estimated in accordance with the provisions of ASC 718 and is~~ recognized ~~as an expense~~ over the requisite service ~~period.~~period, which generally represents the vesting period, and commences at the date of grant based on the fair value of the award.
Stock-based compensation expense recognized in the financial statements is based on awards that are ultimately expected to vest. Accordingly, we are also required to estimate forfeitures at the time of grant, and to revise those estimates in subsequent periods if actual forfeitures differ from estimates. We use historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. Our forfeiture rate estimates are based on an analysis of our actual forfeiture experience, employee turnover behavior, and other factors. The impact of any adjustments to our forfeiture rates would be recorded as a cumulative adjustment in the period of adjustment. To the extent that actual forfeitures differ from our estimates, the difference is recorded as a cumulative adjustment in the period the estimates were revised.

Comprehensive Loss

The Company’s comprehensive loss is equal to its net loss for all periods presented.

Net Loss per Share

~~The Company accounts for and discloses net loss per share in accordance with the FASB ASC Topic 260, “~~~~Earnings per Share~~.”
Basic ~~and diluted~~ net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted ~~earnings~~net loss per share is computed by dividing the Company’s net loss by the weighted average number of common shares outstanding and the impact of all dilutive potential common ~~shares.~~shares outstanding, except where such dilutive potential common shares would be anti-dilutive. Dilutive potential common shares primarily consist of warrants, restricted stock units and stock options.

3. Liquidity and Going Concern

The Company has reported recurring losses from operations since inception and expects that the Company will continue to have negative cash flows from operations for the foreseeable future. Historically, the Company’s primary source of funding has been the sale of its securities. The Company’s ability to continue to fund its operations is dependent on obtaining funding from third parties, such as proceeds from the issuance of debt, sale of equity, or strategic opportunities, in order to maintain its operations. This is dependent on a number of factors, including the market demand or liquidity of the Company’s common stock. There is no guarantee that debt, additional equity or other funding will be available to us on acceptable terms, or at all. Moreover, the global coronavirus pandemic has led to significant uncertainty and increased volatility in the capital markets. While the potential economic impact brought by, and the duration of, the coronavirus pandemic is difficult to assess or predict, if these conditions in the capital markets continue for an extended period of time it may reduce our ability to access capital, which could negatively impact our short-term and long-term liquidity and our ability to complete our planned preclinical and clinical studies on a timely basis, or at all. The ultimate impact of the coronavirus pandemic on our liquidity is highly uncertain and subject to change. While we anticipate that we may experience an impact to our research and development activities, we do not yet know the full extent of potential delays or the impact on our business, financial condition, or our preclinical and clinical trial activities. There may be developments outside of our control that require us to adjust our operating plans and given the nature of the situation, cannot reasonably estimate the impact of the coronavirus on our financial condition, results of operations or cash flows in the future. If we fail to obtain additional funding when needed, we would be forced to scale back or terminate our operations or seek to merge with or to be acquired by another company.

While we believe that the coronavirus pandemic has not had a significant impact on our financial condition and results of operations at this time, the ~~extent to which~~potential economic impact brought by, and the ~~coronavirus pandemic impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity~~duration of, the coronavirus pandemic is difficult to assess or predict. There may be developments outside of our control that require us to adjust our operating plans and given the ~~actions to contain~~nature of the situation, we cannot reasonably estimate the impact of the coronavirus pandemic on our financial conditions, results of operations or ~~treat its impact, among others.~~ cash flows in the future.
The Company believes that its existing cash should be sufficient to fund operations for at least the next 12 months from the date of the release of these financial ~~statements.~~statements.

4. Recent Accounting Pronouncements

In ~~November 2018,~~December 2019, the FASB issued Accounting Standards Update (“ASU”) ~~2018-18, “~~~~Collaborative Arrangements (Topic 808)~~~~” (“~~~~Topic 808~~~~”), which clarifies the interaction between Topic 808 and ASC Topic 606, “~~~~Revenue from Customers~~.” The update provides guidance on whether certain transactions between collaborative arrangement participants should be accounted for with revenue under ASC Topic 606 and provides more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. This ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. This guidance is required to be applied retrospectively to the date of adoption of ASC Topic 606. The Company adopted ASC Topic 606 in the first quarter of 2018 and adopted ASU 2018-18 in the first quarter of 2020. The Company also elected to apply ASU 2018-18 only to contracts that were not completed at the date of initial application of Topic 606. Since the Company has no significant revenue, this ASU has no immediate impact on its condensed consolidated financial statements.
~~In December 2019, the FASB issued ASU~~ 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”).” The amendments in the update simplify the accounting for income taxes by eliminating the exceptions related to the incremental approach for intraperiod tax allocation, the recognition of a deferred tax liability for equity method investments, not recognizing a deferred tax liability for a foreign subsidiary and the general methodology for calculating income taxes in an interim period. The amendments also clarify and simplify other aspects of the accounting for income taxes. The amendments in ASU 2019-12 are effective for public entities for fiscal years, and the interim periods within those fiscal years, beginning after December 20, 2020. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements.
In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815 – 40)” (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to reduce unnecessary complexity in U.S. GAAP. For convertible instruments, the accounting models for instruments issued with beneficial conversion features or cash conversion features are removed. For contracts in an entity’s own equity, ASU 2020-06 simplifies the settlement assessment by removing the requirements to (1) to consider whether the contract would be settled in registered shares, (2) to consider whether collateral is required to be posted, and (3) to assess shareholder rights. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is ~~permitted.~~ permitted, but no earlier than fiscal years beginning after December 15, 2020, and interim periods within those fiscal years.

The adoption of this standard did not have an impact ~~this guidance may have~~ on the Company’s consolidated financial ~~statements and related disclosures.~~statements.

5. Leases

OnIn January ~~22,~~ 2019, the Company amended the lease for its corporate headquarters and primary research facility in Marlborough, Massachusetts. The ~~Company leases~~lease is for a total of 7,581 square feet of office and laboratory space ~~which~~and will expire on March 31, 2024. The lease contains an option to terminate the lease after two years or three years by providing advance written notice of termination pursuant to the terms of the agreement. The exercise of this option was not determined to be reasonably certain and thus is not included in the lease liability on the Company’s balance sheet.Additionally, the lease agreement did not contain information to determine the rate implicit in the lease. As such, the Company calculated its incremental borrowing rate based on what the Company would have to pay to borrow on a collateralized basis over the lease term for an amount equal to the remaining lease payments taking into consideration such assumptions as, but not limited to, the U.S. treasury yield rate and borrowing rates from a creditworthy financial institution using the above lease factors.

6. Debt

On May 11, 2020, the Company received loan proceeds in the amount of $231,252 from Bank of America, N.A., as lender, pursuant to the PPP under the CARES Act. The PPP loan ~~matures on~~had a maturity date of May 11, 2022, ~~and bears~~ interest at a rate of 1% per ~~year.~~year and monthly principal and interest payments that were deferred to the date that the Small Business Administration (the “SBA”) remitted the borrower’s loan forgiveness amount to the lender. When applying for the PPP loan, the Company carefully assessed the requirements for application under the program and believed that the loan was necessary to support its operations. The ~~loan~~loans under the PPP may be forgiven if used for eligible purposes, including payroll, benefits, rent and utilities. Under the Flexibility Act, the definition of a covered period for which a borrower must spend the PPP loan proceeds in order to be eligible for PPP loan forgiveness was extended from an eight (8) week covered period to the earlier of the date that is twenty-four (24) weeks from the date the loan was funded or December 31, 2020. Additionally, monthly principal, interest and other fee payments are deferred until the date on which the determination of PPP loan forgiveness is remitted to the lender, or ten (10) months after the end of the borrower’s loan forgiveness covered period.

The Company carefully assessed the requirements for application under the PPP and believes that the loan is necessary to support its operations. The Company intends to apply for loan forgiveness, but as loan forgiveness has not yet been determined the Company followed the guidance under ~~the FASB ASC Topic 470, “~~~~Debt~~~~” (“~~ASC 470”) in assessing the accounting for the PPP loan proceeds. Per ASC 470, the Company recorded a liability on the balance sheet for the full amount of PPP loan proceeds received and ~~will accrue~~accrued interest over the term of the loan. ~~As the~~The Company ~~has twenty-four weeks from May 11, 2020, or the date the loan was funded, for spending~~believed it used the loan proceeds for the eligible purposes allowed and ~~at least ten months~~applied for full loan forgiveness.

Warrants

The Company first assesses the warrants it issues under the FASB ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”) to determine whether they are within the scope of ASC 480. As there ~~are~~were no instances outside of the Company’s control that could require cash settlement of the warrants ~~including~~issued in the Private Placement and Offering, as well as warrants issued ~~by the Company during the six months ended June 30, 2020,~~in the Company’s ~~outstanding~~prior financing transactions, the warrants are outside the scope of ASC 480.

The Company then applies and follows the applicable accounting guidance in ASC 815. Financial instruments are accounted for as either derivative liabilities or as equity instruments depending on the specific terms of the agreement. The ~~Company’s outstanding~~ warrants issued in the Private Placement and the Offering do not meet the definition of a derivative instrument as they are indexed to the Company’s common stock and classified within stockholders’ ~~equity.~~equity, as are the warrants issued in the Company’s prior financing transactions. Based on this determination, the Company’s warrants ~~issued in the February 2020 Registered Offering, February 2020 Underwritten Offering, April 2020 Offering, as well as all of the Company’s remaining outstanding warrants,~~ are classified within stockholders’ equity.
The following table summarizes the Company’s outstanding equity-classified warrants at ~~June 30, 2020:~~March 31, 2021:

9. Stock-based Compensation

Restricted Stock Units

Restricted stock units (“RSUs”) are issued under the Company’s ~~2012~~2020 Long-Term Incentive Plan or as inducement grants issued outside of the plan to new employees. RSUs are generally subject to graded vesting and the satisfaction of service requirements. Upon vesting, each outstanding RSU will be exchanged for one share of the Company’s common stock. Employee RSU recipients may elect to net share settle upon vesting, in which case the Company pays the employee’s income taxes due upon vesting and withholds a number of shares of equal value. The fair value of the RSUs awarded are based upon the Company’s closing stock price at the grant date and are expensed over the requisite service period.

Stock Options
Stock options are issued under the 2020 Plan or as inducement grants issued outside of the plan to new employees. Stock options are generally subject to graded vesting and the satisfaction of service requirements. Upon the exercise of a stock option, the Company issues new shares and delivers them to the recipient. The Company does not expect to repurchase shares to satisfy stock option exercises.

The Company uses the Black-Scholes option-pricing model to determine the fair value of all its option grants. The risk-free interest rate used for each grant iswas based upon the yield on zero-coupon U.S. Treasury securities with a term similar to the expected life of the related option. The Company’s expected stock price volatility assumption is based upon the Company’s own implied volatility. ~~The~~As the Company has limited stock option exercise information, the expected life assumption used for option grants is based upon the simplified method provided for under ASC 718. The dividend yield assumption is based upon the fact that the Company has never paid cash dividends and presently has no intention of paying cash dividends.

The Company did not grant stock options during the three months ended March 31, 2021 and 2020.

Overview

Phio Pharmaceuticals Corp. is a biotechnology company developing the next generation of immuno-oncology therapeutics based on our self-delivering RNAi (“INTASYL™”) therapeutic platform. Our efforts are focused on silencing tumor-induced suppression of the immune system through our proprietary INTASYL platform with utility in immune cells and the tumor micro-environment. Our goal is to develop powerful INTASYL therapeutic compounds that can weaponize immune effector cells to overcome tumor immune escape, thereby potentially providing patients a powerful new treatment option that goes beyond current treatment modalities.

Our development efforts are based on our broadly patented INTASYL technology platform. Our INTASYL compounds do not require a delivery vehicle to penetrate into tissues and cells and are designed to “silence” or down-regulate, the expression of a specific gene which is over-expressed in cancer. We believe that our INTASYL platform uniquely positions the Company in the field of immuno-oncology ~~because of this and~~for the following reasons:

· Efficient uptake of INTASYL ~~to immune~~by target cells obviating the need for facilitated delivery (mechanical or formulation);
· Does not require permanent genetic modification;

· Can target multiple genes (i.e. multiple immunosuppression pathways) in a single therapeutic entity;

· Gene silencing by INTASYL has been shown to have a sustained, or long-term, effect in vivo;

16
· Favorable clinical safety profile of INTASYL with local administration; and

· Can be readily manufactured under current good manufacturing practices.

15
~~The~~In contrast to other RNA technologies and platforms, the self-delivering nature of our ~~compounds~~INTASYL platform makes ~~INTASYL~~it ideally suited for use with adoptive cell ~~transfer~~therapy (“ACT”) treatments ~~and~~as well as for direct therapeutic use. ACT consists of the infusion of immune cells with antitumor properties, after growing them in a lab to large numbers. These cells can be derived from unmodified (i.e. naturally occurring) immune cells, immune cells isolated from resected tumors, or genetically engineered immune cells that recognize tumor cells.
Regardless of the source of immune cells (ACT or naturally occurring immune cells), in patients with solid tumors, these cells ~~face~~have several ~~hurdles.~~shortcomings that inhibit their full therapeutic potential. By using INTASYL technology during the manufacturing of such ACT cell products we can improve the phenotype and function of these cells, potentially leading to better therapeutic outcomes. Multiple inhibitory mechanisms restrain immune cells from effectively eradicating tumors, including immune checkpoints, reduced cell fitness and cell persistence. Furthermore, the immunosuppressive tumor micro-environment (the “TME”) can pose a formidable barrier to immune cell infiltration and function. By using INTASYL based drugs administered directly, we can also reprogram cells in the TME to help overcome these immunosuppressive mechanisms.

We have developed a product platform based on our INTASYL technology that allows easy, precise, rapid, and selective non-genetically modified programming of ACT cells (ex vivo, during manufacturing) and of the TME (in vivo, by local application), resulting in reduced immune inhibition and in improved immunotherapy.

INTASYL Use To Improve Adoptive Cell ~~Transfer~~Therapy Products
ACT ~~includes~~is a ~~number~~form of ~~different types~~immune therapy based on the use of ~~immunotherapy treatments. These treatments use~~ immune cells, isolated from patients, donors or retrieved from allogeneic immune cell banks. They are grown in a lab to large numbers, followed by administering them to the ~~body~~patient to fight ~~the cancer cells.~~cancer. Sometimes, immune cells that naturally recognize a tumor are used, while other times immune cells are modified or “genetically engineered” to make them recognize and kill the cancer cells. There are several types of ACT, including: a.) non-engineered cell therapy in which immune cells are grown from the patient’s tumor or blood, such as tumor infiltrating lymphocytes (“TILs”), or from donor blood or tissue such as natural killer (“NK”) cells, dendritic cells (“DC”) and macrophages, and b.) genetically engineered immune cells that are genetically modified to recognize specific tumor proteins and to remain in an activated state (such as T cell receptor technology (“TCRs”), chimeric antigen receptor (“CAR”) T cells, or CAR-NK cells).

~~In ACT, such immune cells are then expanded and modified before being returned and used to treat the patient.~~ Multiple inhibitory mechanisms restrain immune cells used in ACT from effectively eradicating tumors, including immune checkpoints, reduced cell fitness and cell persistence, and other barriers to immune cell infiltration and function mainly in solid tumors. We believe our INTASYL compounds are ideally suited to be used in ~~combination with~~ ACT products. With INTASYL compounds, we can unlock the full potential of ACT, by improving the immune cell function, differentiation and metabolism, in order to make these immune cells more effective without the need for additional complicated manufacturing steps and/or genetic engineering.

Our approach builds on well-established methodologies of ACT and involves the treatment of immune cells with our INTASYL compounds ex vivo while they are grown in the lab and before administering them to the patient. Because our INTASYL compounds do not require a delivery vehicle, in contrast to other RNA technologies, to penetrate into the cells, we are able to enhance the function of these cells by merely adding our INTASYL compounds during the expansion process and without the need for genetic engineering, without the need for complex delivery vehicles or formulations, and without additional needed complex manufacturing steps. By ~~merely~~ adding INTASYL to the cell culture media used during the cell expansion, we can reduce or eliminate the expression of genes that make the immune cells less effective. For example, with our INTASYL compounds, we can reduce the expression of immunosuppressive proteins by the therapeutic immune cells, potentially enabling them to overcome tumor resistance mechanisms and thus improving their ability to destroy the tumor cells. In various types of immune cells tested to date, INTASYL treatment results in potent silencing ~~through~~with close to 100% transfection efficiency and while maintaining ~~nearly full~~ cell ~~viability.~~viability and cell growth rate. After expanding these cells and enhancing them with INTASYL ex vivo, they are returned to the patient for treatment.

Our lead product candidate and most advanced program being developed in ACT is PH-762, an INTASYL compound that targets the checkpoint protein PD-1. Checkpoint proteins, such as PD-1, normally act as a type of “off switch” that ~~prevents~~prevent T cells from attacking certain cells, such as cancer cells, in the body. ~~Our~~ T cells are immune cells that protect the body from cancer cells and infections.
17

Data developed by Phio and with collaborators has shown that PH-762 silences PD-1 checkpoint expression, thereby removing the “off switch” and resulting in enhanced T cell activation and tumor cytotoxicity. Experimental data shows that PH-762 can silence the expression of PD-1 in target human T cells in a potent and durable manner, and can increase the function of patient derived TILs for use in ACT, and of CAR-T cells used in ACT, showing that PH-762 is ~~suitable~~applicable for use in both in ACT and as a standalone direct therapeutic.
In March 2021, the Company announced that it entered into a clinical development collaboration with AgonOx, Inc. (“AgonOx”), a private company developing a pipeline of novel immunotherapy drugs targeting key regulators of the immune response to cancer. Under the agreement, the companies will collaborate on the development of novel T cell-based therapies using PH-762 and AgonOx’s “double positive” (DP) TIL technology. AgonOx has demonstrated that their DP CD8+ T cells isolated from human solid tumors (DP TILs) have increased tumor killing activity when compared to TILs that were not enriched prior to expansion. Preclinical data from AgonOx in collaboration with Phio has shown that treating DP TILs with PH-762 increases the tumor killing activity of the DP TILs even further (a two-fold increase). As a result, the use of PH-762 treated DP TILs is expected to enhance therapeutic ~~through intra-tumoral injection. This supports~~responses in cancer data. Based on these data showing that the combination of our technologies can result in TIL therapeutics, our collaboration will focus on conducting a clinical study for PH-762 treated DP TILs. Under the terms of the collaboration agreement, AgonOx will receive financial support for the clinical trial from Phio and Phio will be entitled to certain future development milestones and sales-related royalty payments from AgonOx’s DP TIL technology. In collaboration with AgonOx, we are planning a clinical trial in ACT with PH-762 and AgonOx’s DP TIL technology. We are in the process of finalizing the investigational new drug (“IND”)-enabling studies and preparing for regulatory submission in the third quarter of 2021 and anticipate commencing the start of the clinical trial soon thereafter.
Our second product candidate in ACT is PH-894, an INTASYL compound that targets BRD4 which is a regulator of gene expression impacting cell differentiation. In previous studies, PH-894 has been shown to improve T cell function and persistence by differentiating T cells into a more active state (stem-cell like memory phenotype). Data, completed in partnership with the Karolinska Institutet in Sweden, demonstrated that the application of PH-894, was shown to silence BRD4 in human T cells during expansion for ACT, which has the potential to confer superior anti-tumor activity, for example by improving T cell persistence. With this data, we expanded our collaboration with the Karolinska Institutet to build upon these findings and develop INTASYL ~~technology~~compounds for additional targets and cell types toward clinical application in ~~immunotherapy~~areas of ~~cancer.~~the Karolinska Institutet’s ongoing clinical research.

We are also developing our INTASYL compound PH-804 for use in ACT. PH-804 targets the suppressive immune receptor TIGIT, which is a checkpoint protein present on T cells and NK cells. ~~To date, we~~We have shown that PH-804 can silence the expression of TIGIT in NK cells and T cells, overcoming their “off switch” and the cells becoming “weaponized” to kill cancer cells.
16
Our third recently announced product candidate is PH-894, an INTASYL compound that targets BRD4, a regulator of gene expression impacting cell differentiation. In previous studies, PH-894 has been shown to improve T cell function and persistence by differentiating T cells into a more active state (effector memory phenotype). Data, completed in partnership with the Karolinska Institutet, demonstrated that the application of PH-894, was shown to silence BRD4 in human T cells during expansion for ACT, which has the potential to confer superior anti-tumor activity. With this data, as well as results with several compounds in both T cells and NK cells, we announced the expansion of our collaboration with the Karolinska Institutet in November 2019 to build upon these findings and develop INTASYL compounds for additional targets and cell types toward clinical application in areas of the Karolinska Institutet’s ongoing clinical research.
~~In March 2020, we entered into a collaboration and option agreement with Medigene AG and the Helmholtz Zentrum München (“~~~~HMGU~~~~”). This three-way collaboration expands upon our outstanding research agreement with HMGU to design and develop novel candidates for the use~~Direct Therapeutic Use of INTASYL ~~compounds in ACT to enhance immune cell function. Under~~Towards the agreement, Medigene AG will contribute expertise regarding clinical development, as well as proprietary research material and has the option to an exclusive license for the clinical and/or commercial development of certain INTASYL immune cell enhancers.
Tumor Micro-Environment
The TME is the environment that surrounds and feeds a tumor, including normal cells, blood vessels, immune cells, and the extracellular matrix. The TME is an immunosuppressive environment that inhibits the immune system’s natural ability to recognize and destroy tumor cells by negatively impacting how immunosuppressive cells are being attracted and activated. Reprogramming different components of the TME may overcome resistance to immunotherapy. Such reprogramming of the TME by INTASYL compounds through direct local administration into the tumor could potentially become an important form of therapy. The Company has previously shown in a clinical setting that our INTASYL compounds are safe and well-tolerated following local administration, therefore we believe that our INTASYL technology can not only be used with ACT, but can also be used as an independent therapeutic platform.

We ~~have pipeline programs in place for the development of~~are developing our PH-762, PH-894 and PH-804 INTASYL compounds also for use as direct ~~administration into~~therapeutics to reprogram the ~~tumor, including the use of PH-762, PH-804 and PH-894~~TME, for example by in situ transfection and activation of immune cells in the TME.

~~Data presented~~Animal studies conducted by the Company showed that local administration of PH-894 or the mouse version of PH-762 through intra-tumoral injection resulted in ~~January 2020 from~~potent anti-tumoral effects. The treated animals showed a complete and statistically significant inhibition of tumor growth, whereas placebo treated animals displayed exponential tumor growth. inIn vivo studies performed by the Company with PH-804 showed that intra-tumoral injection of a mouse version of PH-804 reduced the tumor growth in colorectal carcinoma tumor bearing mice, which was shown to inhibit tumor growth and was correlated with the silencing of TIGIT mRNA expression and in increase in cytotoxic effector T cells in the TME.

Building on the animal data with PH-804, the Company conducted several animal studies with a mouse version of PH-762 and with PH-894 in a validated mouse model of hepatocellular carcinoma. These studies showed that local administration of the mouse version of PH-762 or PH-894 through intra-tumoral injection resulted in potent anti-tumoral effects. The treated animals showed a complete and statistically significant inhibition of tumor growth, whereas placebo treated animals displayed exponential tumor growth.
18
The combined PH-804, PH-762, and PH-894 data further shows that INTASYL compounds can trigger associated changes in the TME such as an increase of TILs, including CD8+ T cells responsible for tumor cell killing, and an increase of activation markers on these cells. These preclinical findings demonstrate that direct injection of INTASYL compounds can successfully infiltrate solid tumors and impact the TME by activating the immune response in animal models of solid tumors resulting in reduced tumor growth. ~~This is one of the~~A key ~~challenges~~challenge for many other immunotherapy platforms is to be able to achieve an adequate therapeutic effect in solid ~~tumors.~~tumors with an acceptable safety profile. Many of the available systemic immuno-therapeutics indeed come with dose limiting immune-related adverse events, which we believe can be mitigated with local INTASYL treatment.
Based on our positive preclinical data, the Company is preparing for a clinical study with PH-762 using intra-tumoral administration for patients with advanced melanoma. The required preclinical studies and regulatory submission needed to initiate the clinical trial with PH-762 as a direct therapeutic are being finalized. The clinical trial will be conducted at the Gustave Roussy Institute, which is one of the largest cancer centers in Europe, with Dr. Caroline Robert as our lead principal investigator. The Company expects to start the clinical trial evaluating the use of PH-762 as a direct therapeutic in the fourth quarter of 2021.

We are also investigating other relevant compounds for TME targets, such as PH-790, an INTASYL compound targeting PD-L1. PD-L1 is a protein formed by cancer cells that activate the PD-1 “off switch” on immune cells. Our approach with PH-790 is to block the formation of the PD-L1 protein, which may prevent cancer cells from inactivating T cells and attack the ~~cancer,~~cancer. Recent data presented demonstrated that the antitumoral efficacy of our individual pipeline products, PH-762, PH-790 and ~~will~~PH-804, can be ~~evaluated alongside PH-762.~~further improved by combining them in a single drug treatment. We have shown that we can efficiently and potently target multiple proteins in a single drug treatment. Animal data showed that the combination of our INTASYL compounds in a single formulation (at suboptimal doses of the individual agents) inhibited tumor growth without having a negative impact on the tolerability of the treatment.

Impact of COVID-19 on our Business

In December 2019, a novel strain of coronavirus that causes COVID-19 was reported to have surfaced in Wuhan, China and has since spread to other parts of the world, including the United States. In March 2020, the World Health Organization (the “WHO”) declared the outbreak a pandemic.

Health and Safety

From the first signs of the outbreak, we have taken proactive measures intended to protect the health and safety of our employees. We have implemented safety measures following the guidance provided by the WHO, ~~and~~ the Centers for Disease Control (the “CDC”) ~~such as~~and governmental authorities, which include formal policies related to working remotely for employee personnel who do not need to be physically present in our ~~premises,~~offices, the wearing of face masks while in the office, physically distancing workspaces, cleaning protocols, staggered scheduling and social distancing protocols.

Operations

~~The coronavirus pandemic is affecting the United States and global economies and as a result, government authorities~~Our operations have ~~implemented restrictions and~~continued to operate with limited certain operations, such as limits on the number of people at a gathering, travel restrictions and stay-at-home orders, to try and slow the spread of coronavirus. Our office and lab space are located in one facility in Marlborough, Massachusetts and on March 23, 2020, Massachusetts ordered most physical business workplaces closed, mandating work-from-home arrangements, where feasible, in response to the coronavirus pandemic. The order excluded businesses that provide certain essential services, which included companies operating in the biotechnology and life sciences industry. As a result, our facility remained operational with employee personnel who did not need to be physically present in our premises working remotely during that time.
On May 18, 2020, Massachusetts commenced its four phased approach and re-opening plan of the economy, which allows for the gradual re-opening of each sector, industry and business in line with state mandated workplace safety standards and sector-specific protocols and best practices. The Company’s facilities remain operationalimpact and are operating in accordance with ~~Massachusetts’ mandated requirements, as well as in accordance with the~~ federal and state government, WHO and CDC guidelines. We have implemented enhanced safety measures, as discussed above, and ~~other governmental authority guidelines.

If the ~~measures~~impact to ~~contain the outbreak~~their operations continue or ~~are extended,~~extend, it may in turn affect our ~~operations~~operations. The Company has undertaken efforts to mitigate potential future impacts by identifying and ~~those~~engaging alternative third-party service providers and suppliers, and because of that, to date the Company has not seen a material impact to its program’s anticipated timelines resulting from delays from our third-party service providers. For example, by engaging different contract manufacturers, we believe that we have a sufficient supply of our INTASYL compounds to conduct our ongoing preclinical studies and initial clinical activities. However, the ultimate impact to the third parties on which we rely ~~including causing disruptions~~is highly uncertain and subject to change. Without a swift and sustained improvement of the impacts experienced by our third-party suppliers and service providers, the effects of our mitigation efforts will diminish and may result in ~~the supplies we order, outsourced development services for our product candidates and the conduct of current and planned preclinical and clinical studies. We have not yet experienced any significant~~material impacts ~~or interruptions~~ to our ~~supply chain or third-party vendors as a result of~~operations. If the ~~coronavirus pandemic, but are starting to see some of the third-parties on which we rely becoming impacted. If the~~global measures to contain the ~~outbreak~~pandemic are continued or extended, it may affect our operations and those of our service providers. Without a swift improvement of the current situation, we may experience significant impacts to certain of our development activities outsourced to third-party service providers beginning in the second half of 2020. For example, our development activities may get delayed due to the availability and restrictions on shipment of critical materials that are needed for these development activities. Thus far, we have been able to engage with third-party service providers in areas with limited or no impact (e.g. countries with limited or no restrictions), but with the global spread of the virus and associated restrictions, this is no longer possible. Our service providers, for example those performing required preclinical research studies, are now facing impacts to their operations, including restrictions on the availability of critical materials that are needed for this type of research. If the measures to contain the outbreak are extended or further expanded,insufficient, it could reduce or delay the availability of supplies and services that we purchase and ~~outsource. This~~rely on, which may in turn slow or delay our ~~research~~preclinical and ~~development~~clinical activities, and/or result in higher costs.
~~We anticipate a decline in the commencement of future clinical trials, at least in the short-term, as many Institutional Review Boards (the “~~~~IRB~~”) are currently focused on reviewing and approving clinical trial protocols related to COVID-19. Additionally, due to the implementation of restrictive measures such as stay-at-home orders by government authorities in the United States and global economies to try and contain the spread of coronavirus, we anticipate a significant decline, at least in the short-term, in the enrollment of patients in clinical trials outside of those related to COVID-19.

With the global spread of the coronavirus and the associated safety measures to contain the spread by governmental authorities, a delay in the commencement of new clinical trials and in the enrollment and participation of patients in clinical trials may occur. The steps required ~~studies and steps needed~~for us to initiate our clinical trials with PH-762 in the second half of 2021 ~~timeframe~~ are continuing and ongoing, however, the ~~ultimate impact of the coronavirus pandemic is highly uncertain and subject to change. The~~ Company does not yet know the full extent of potential delays or impacts onrelated to its ~~business and preclinical and~~planned clinical ~~trial~~ activities.

Liquidity and Capital Resources

While we believe that the coronavirus pandemic has not had a significant impact on our financial condition ~~and results of operations~~ at this time, the extent to which the coronavirus pandemic impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus pandemic and the actions to contain the coronavirus or treat its impact, among others. ~~We believe that~~

~~In addition, risk factors identified in our Annual Report on Form 10-K for the year ended December 31, 2019 under the heading “~~~~Risk Factors~~~~,” which was filed with the SEC on March 26, 2020, should be read in conjunction with Part II—Item 1A, “~~~~Risk Factors~~~~,” included herein for updates to our risk factors regarding risks associated with the COVID-19 pandemic.~~

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with ~~GAAP~~accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions and could have a material impact on our reported results.
There have been no significant changes to our critical accounting policies ~~since the beginning of this fiscal year. Our critical accounting policies are described~~disclosed in the ~~“Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our~~Company’s most recent Annual Report on Form ~~10-K for the year ended December 31, 2019, which we filed with the SEC on March 26, 2020.~~10-K.

Research and Development Expenses

Research and development expenses relate to compensation and benefits for research and development personnel, facility-related expenses, supplies, external services, costs to acquire technology licenses, research activities under our research collaborations, expenses associated with preclinical and clinical development activities and other operating costs. Our research and development programs are focused on the development of immuno-oncology therapeutics based on our INTASYL therapeutic platform.

Other income for the three months ended March 31, 2021 increased by $226,000 as compared with the three months ended March 31, 2020, primarily due to the full forgiveness of the Company’s PPP loan by the Small Business Administration in the first quarter of 2021 as compared to the prior year period.

Liquidity and Capital Resources

~~On August 8, 2017, the Company entered into a purchase agreement (the “~~~~2017 Purchase Agreement~~~~”) and a registration rights agreement with Lincoln Park Capital Fund, LLC (“~~~~LPC~~”), pursuant to which the Company had the right to sell to LPC up to $15,000,000 in shares of the Company’s common stock, subject to certain limitations and conditions set forth therein, over the 30-month term of the 2017 Purchase Agreement. The 2017 Purchase Agreement expired on April 1, 2020 and a total of 9,000 shares of common stock were sold to LPC for net proceeds of $1,602,000 under the 2017 Purchase Agreement.
~~On August 7, 2019, the Company entered into a purchase agreement (the “~~~~2019 Purchase Agreement~~”) and a registration rights agreement with LPC, pursuant to which the Company has the right to sell to LPC up to $10,000,000 in shares of the Company’s common stock over the 30-month term of the 2019 Purchase Agreement, subject to certain limitations and conditions. The 2019 Purchase Agreement initially limits the Company’s issuance of shares of common stock to LPC to 19.99% of the Company’s shares outstanding on the date of the 2019 Purchase Agreement unless stockholder approval is obtained to issue more than such amount or the average price of all sales under the 2019 Purchase Agreement exceed certain amounts as set forth in the 2019 Purchase Agreement. To date, no shares of common stock have been sold to LPC under the 2019 Purchase Agreement.
On February 6, 2020, the Company closed its February 2020 Registered Offering. Net proceeds to the Company from the February 2020 Registered Offering were $1,467,000 after deducting placement agent fees and offering expenses paid by the Company.
On February 13, 2020, the Company closed its February 2020 Underwritten Offering. Net proceeds from the February 2020 Underwritten Offering were $7,093,000 after deducting underwriting discounts and commissions and offering expenses paid by the Company.
On April 2, 2020, the Company closed its April 2020 Offering. Net proceeds to the Company from the April 2020 Offering were $3,527,000 after deducting placement agent fees and offering expenses paid by the Company.
We had cash of $18,864,000 as of June 30, 2020, compared with $6,934,000 as of December 31, 2019. We have reported recurring losses from operations since inception and expect that we will continue to have negative cash flows from our operations for the foreseeable future. Historically, the Company’s primary source of funding has been through the sale of its securities. In the future, we will be dependent on obtaining funding from third parties, such as proceeds from the issuance of debt, sale of equity, or strategic opportunities, in order to maintain our operations. ~~There is no guarantee~~We have reported recurring losses from operations since inception and expect that ~~debt, additional equity or other funding~~we will ~~be available~~continue to ~~us on acceptable terms, or~~have negative cash flows from our operations for the foreseeable future.

Off-Balance Sheet Arrangements

In connection with certain license agreements, we are required to indemnify the licensor for certain damages arising in connection with the intellectual property rights licensed under the agreement. In addition, we are a party to a number of agreements entered into in the ordinary course of business that contain typical provisions that obligate us to indemnify the other parties to such agreements upon the occurrence of certain events. These indemnification obligations are considered off-balance sheet arrangements in accordance with ASC Topic 460, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” To date, we have not encountered material costs as a result of such obligations and have not accrued any liabilities related to such obligations in our financial statements. See Note 78 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, ~~2019,~~2020, which was filed with the SEC on March ~~26, 2020,~~25, 2021, for further discussion of these indemnification agreements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (who is also acting as our principal financial officer) and our Principal Accounting Officer, evaluated the effectiveness of ~~our~~ disclosure controls and procedures as(as defined in Rules 13a-15(e) and 15d-15(e) under the ~~Securities~~ Exchange ~~Act of 1934, as amended (the “~~~~Exchange Act~~~~”),~~Act) as of the end of the period covered by this report to ensure that information that we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. We believe that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this report, management, with the participation of our Chief Executive Officer (who is also acting as our principal financial officer) and our Principal Accounting Officer, concluded that our disclosure controls and procedures were effective as of such date.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the ~~six~~three months ended ~~June 30, 2020~~March 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, the Company may become a party to various legal proceedings and complaints arising in the ordinary course of business. There are none deemed to be material at this time.

ITEM 1A. RISK FACTORS

Please carefully consider the information set forth in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2019~~2020 filed with the SEC on March ~~26, 2020.~~25, 2021. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This Quarterly Report on Form 10-Q also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including these risks. Additional risks not currently known or currently material to us may also harm our business.

~~Risks Relating to Our Business and Industry~~
~~Our business and operations may be materially and adversely affected by the recent coronavirus outbreak.~~
In December 2019, a novel strain of coronavirus was reported to have surfaced in China and has since spread to other parts of the world. In March 2020, the WHO declared the outbreak a pandemic. The coronavirus pandemic is affecting the United States and global economies and as a result, government authorities have implemented restrictions and limited certain operations, such as limits on the number of people at a gathering, travel restrictions and stay-at-home orders, to try and slow the spread of coronavirus. These mandates generally excluded businesses that provide certain essential services, such as companies operating in the biotechnology and life sciences industry. As a result, our facility remained operational with employee personnel who did not need to be physically present in our premises working remotely during that time. In May 2020, Massachusetts, along with other states in the United States, began its re-opening of the economy, allowing for the gradual opening of businesses in line with state mandated workplace safety standards, specific protocols and best practices. The Company’s facilities remain operational and are operating in accordance with federal and state governmental authority guidelines. Employee personnel who do not need to be physically present on our premises are continuing to work remotely, but have the ability to be on site as required. While the majority of these mandates have specific end dates, they may be modified or extended and as a result there is uncertainty regarding the length of time that such measures will be place. We believe the impact to our internal operations has not been material thus far, however, current and future restrictions may further impact our operations and may slow or diminish our research and development activities.
In response to the coronavirus pandemic, we have taken proactive measures to protect the health and safety of our employees. We have implemented safety measures following the guidance provided by the WHO and the CDC such as working remotely for employee personnel who do not need to be physically present in our premises, social distancing protocols, suspending travel and extensively and frequently disinfecting our workspaces. We have experienced limited absenteeism from our employees, but absenteeism may increase in the future, employees working remotely may experience limited productivity due to the resources available at home or we may not be able to maintain the necessary information technology infrastructure to adequately support our employees working remotely. ~~Further, our increased reliance on remote access to our information systems increases our exposure to potential cybersecurity breaches.~~ We expect to continue following these safety measures and may take further actions as we require, as government authorities require or recommend, or as we determine to be in the best interests of our employees, partners and suppliers.
The extent to which the coronavirus pandemic impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. We do not yet know the full extent of potential delays or the impact on our business, financial condition, or our preclinical and clinical trial activities. There may be developments outside of our control that require us to adjust our operating plans and given the nature of the situation, cannot reasonably estimate the impact of the coronavirus pandemic on our financial condition, results of operations or cash flows in the future.
23
~~We rely upon third parties for the supply of our product candidates, other resources and the conduct of our preclinical and clinical activities.~~
If the measures to contain the coronavirus outbreak continue or are extended, it may adversely affect our operations and those of third parties on which we rely, including causing disruptions in the supplies we order, outsourced development services for our product candidates and the conduct of current and planned preclinical and clinical studies. We have not yet experienced any significant impacts or interruptions to our supply chain or third-party vendors as a result of the coronavirus pandemic, but are starting to see some of the third-parties on which we rely becoming impacted. If the measures to contain the outbreak are continued or extended, it may affect our operations and those of our service providers. Without a sustained improvement of the current situation, we may experience significant impacts to certain of our development activities outsourced to third-party service providers beginning in the second half of 2020. Thus far, we have been able to engage with third-party service providers in areas with limited or no impact (e.g. countries with limited or no restrictions), but with the global spread of the virus and associated restrictions, this is no longer possible. Our service providers, for example those performing required preclinical research studies, are now facing impacts to their operations, including restrictions on the availability of critical materials that are needed for this type of research. If the measures to contain the outbreak are extended or further expanded, it could reduce or delay the availability of supplies and services that we purchase and outsource or result in closures of businesses that we work with. This may in turn slow or delay our research and development activities, and/or result in higher costs. The ultimate impact of the coronavirus pandemic is highly uncertain and subject to change. The Company does not yet know the full extent of potential delays or impacts on its business and preclinical and clinical trial activities.
Anticipated declines in the commencement of and enrollment of clinical trials, at least in the short-term, may cause delays in any future planned clinical trials for our product candidates and may adversely affect our business.
~~The first stage of the Federal Drug Administration (the “~~~~FDA~~”) approval process for a new biologic or drug involves the submission of an investigational new drug application, which includes the clinical protocol along with the approval of the IRB at the institutions participating in the trials prior to commencement of human clinical trials. We anticipate a decline in the commencement of clinical trials, at least in the short-term, as regulatory authorities and IRBs are currently focused primarily on reviewing and approving clinical trial protocols related to COVID-19. Additionally, due to the implementation of restrictive measures such as stay-at-home orders by government authorities in the United States and global economies to try and contain the spread of coronavirus, we anticipate a significant decline, at least in the short-term, in the enrollment of patients in clinical trials outside of those related to COVID-19. The impact on clinical trial operations may be temporarily delayed or regulatory clearances and approvals paused. Therefore, our planned preclinical and clinical activities, including the commencement of clinical trials for our drug candidates, may be temporarily delayed or paused as a result, which may, in turn, impact our expected development milestones.
The required studies and steps needed to initiate clinical trials with PH-762 in the 2021 timeframe are continuing and ongoing, however, we are reliant on third-party service providers for certain of our preclinical and clinical activities who may be negatively impacted by the implementation of restrictive measures by governmental authorities which are difficult to assess or predict at this time. In turn, our PH-762 programs may be delayed as a result. The ultimate impact of the coronavirus pandemic is highly uncertain and subject to change. The Company does not yet know the full extent of potential delays or impacts on its business and preclinical and clinical trial activities and these effects could have a material impact on the Company’s liquidity, capital resources, operations and business and those of the third parties on which we rely.
~~We may not be able to obtain sufficient financing and may not be able to develop our product candidates.~~
~~We believe that our current cash on hand should be sufficient to fund our operations for at least the next twelve months from the date of the release of these financial statements.~~ ~~However, w~~e have generated significant losses to date, have not generated any product revenue and may not generate product revenue in the foreseeable future, or ever. We expect to incur significant operating losses as we advance our product candidates through drug development and the regulatory process. In the future, we may need to issue equity or incur debt in order to fund our planned expenditures, as well as to make acquisitions and other investments. We cannot assure you that equity or debt financing will be available to us on acceptable terms, or at all. Were we able to access capital, there may be risks associated with the terms of such capital, including dilution (in the case of equity offerings), risks of repayment and default (in the case of debt) and reputational risks (in the case of obtaining government assistance, such as through a PPP loan). If we cannot, or are limited in the ability to, issue equity, incur debt or enter into strategic collaborations, we may be unable to fund the discovery and development of our product candidates, address gaps in our product offerings or improve our technology.
24
Moreover, the global coronavirus pandemic has led to significant uncertainty and increased volatility in the capital markets. Additionally, while the potential economic impact brought by, and the duration of, the coronavirus pandemic is difficult to assess or predict, the impact of the coronavirus on the global financial markets may reduce our ability to access capital, which could negatively impact our short-term and long-term liquidity and our ability to complete our preclinical and planned clinical studies on a timely basis, or at all. The ultimate impact of coronavirus is highly uncertain and subject to change. While we anticipate that we will experience an impact to our research and development activities, we do not yet know the full extent of potential delays or the impact on our business, financial condition, or our preclinical and clinical trial activities. There may be developments outside of our control that require us to adjust our operating plans and given the nature of the situation, cannot reasonably estimate the impact of the coronavirus on our financial condition, results of operations or cash flows in the future.

· ~~To retain qualified employees, particularly in light of intense competition for qualified personnel;~~
· ~~To manufacture products ourselves or through third parties;~~
· ~~To market our products, either through building our own sales and distribution capabilities or relying on third parties; and~~
· ~~To acquire new technologies, licenses or products.~~
