PHIO PHARMACEUTICALS CORP.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. Organization and Significant Accounting Policies
Nature of Operations
Phio Pharmaceuticals Corp. (“Phio” or the “Company”) is a clinical stage biotechnology company whose proprietary INTASYL™ self-delivering RNAi technology platform is designed to make immune cells more effective in killing tumor cells. Phio is developing therapeutics that are designed to leverage INTASYL to precisely target specific proteins that reduce the body’s ability to fight cancer, without the need for specialized formulations or drug delivery systems.
Effective January 26, 2023, the Company completed a 1-for-12 reverse stock split of the Company’s outstanding common stock, including reclassifying an amount equal to the reduction in par value to additional paid-in capital. The reverse stock split did not reduce the number of authorized shares of the Company’s common or preferred stock. All share and per share amounts have been adjusted to give effect to the reverse stock split.
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.
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 (“GAAP”). Certain information and footnote disclosures that are included in the Company’s annual consolidated financial statements, but that are not required for interim reporting purposes, have been condensed or omitted. Additionally, the Company made adjustments to the outstanding stock option and unvested restricted stock unit balances, and related per share amounts, at December 31, 2022 to reflect final revisions to thesethose outstanding equity awards as a result of the Company’s reverse stock split. The adjustment had no effect on the Company’s condensed consolidated financial statements. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s most recent Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the Securities and Exchange Commission (the “SEC”) on March 22, 2023 (the “2022 Form 10-K”). 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.
Use of Estimates
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 as of 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, useful lives of property and equipment, income taxes, and the valuation allowance on the Company’s deferred tax assets. On an ongoing basis the Company evaluates its estimates and bases its estimates on historical experience and other relevant assumptions that the Company believes are reasonable under the circumstances. Actual results could differ materially from these estimates.

Liquidity
The Company has reported recurring losses from operations since inception and expects to continue to have negative cash flows from operations for the foreseeable future. Historically, the Company’s primary source of funding has been from sales 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 the Company on acceptable terms, or at all. If the Company fails to obtain additional funding when needed, the Company would be forced to scale back or terminate its operations or seek to merge with or to be acquired by another company.
The Company has limited cash resources, has reported recurring losses from operations since inception and has not yet received product revenues. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern, and the Company’s current cash resources may not provide sufficient capital to fund operations for at least the next 12 months from the date of the release of these financial statements. The continuation of the Company as a going concern depends upon the Company’s ability to raise additional capital through an equity offering, debt offering and/or strategic opportunity to fund its operations. There can be no assurance that the Company will be successful in accomplishing these plans in order to continue as a going concern. These financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.
Summary of Significant Accounting Policies
There have been no material changes to the significant accounting policies disclosed in the Company’s 2022 Form 10-K.
Recent Accounting Pronouncements
There have been no recent accounting pronouncements that have significantly impacted this Quarterly Report on Form 10-Q, beyond those disclosed in the Company’s 2022 Form 10-K.
2. Collaboration Agreement
AgonOx, Inc. (“AgonOx”)
In March 2021, the Company entered into a clinical co-development collaboration agreement (the “Clinical Co-Development Agreement”) with AgonOx, a private company developing a pipeline of novel immunotherapy drugs targeting key regulators of the immune response to cancer. Under the Clinical Co-Development Agreement, Phio and AgonOx are working to develop a T cell-based therapy using the Company’s lead product candidate, PH-762, and AgonOx’s “double positive” tumor infiltrating lymphocytes (“DP TIL”) technology. Per the terms of the Clinical Co-Development Agreement, the Company committed to provide financial support for development costs of up to $4,000,000 to AgonOx for expenses incurred to conduct a Phase 1 clinical trial of PH-762 treated DP TIL in patients with advanced melanoma and other advanced solid tumors.
The Company will recognize its share of costs arising from research and development activities performed by AgonOx in the Company’s financial statements in the period AgonOx incurs such expense. Phio will be entitled to certain future development milestones and low single-digit sales-based royalty payments from AgonOx’s licensing of its DP TIL technology.
The Company recognized approximately $181,000606,000 and $300,000906,000 of expense in connection with these efforts during the three and sixnine months ended JuneSeptember 30, 2023, respectively. No expense under the Clinical Co-Development Agreement was recognized during the three and sixnine months ended JuneSeptember 30, 2022.
There is approximately $3,570,0002,964,000 of remaining costs not yet incurred under the Clinical Co-Development Agreement as of JuneSeptember 30, 2023.

3. Fair Value of Financial Instruments
The Company follows the provisions of the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement,” for the Company’s financial assets and liabilities that are re-measured and reported at fair value each reporting period and are re-measured and reported at fair value at least annually using a fair value hierarchy that is broken down into three levels. Level inputs are defined as follows:
Level 1 – quoted prices in active markets for identical assets or liabilities.
Level 2 – other significant observable inputs for the assets or liabilities through corroboration with market data at the measurement date.
Level 3 – significant unobservable inputs that reflect management’s best estimate of what market participants would use to price the assets or liabilities at the measurement date.
At JuneSeptember 30, 2023 and December 31, 2022, the Company categorized its restricted cash of $50,000 as Level 2 hierarchy. Restricted cash consists of certificates of deposit held by financial institutions as collateral for the Company’s corporate credit cards. The assets classified as Level 2 have initially been valued at the applicable transaction price and subsequently valued, at the end of each reporting period, using other market observable data. Observable market data points include quoted prices, interest rates, reportable trades and other industry and economic events.
The carrying amounts of cash, accounts payable and accrued expenses of the Company approximate their fair values due to their short-term nature.
4. Leases
In January 2019, the Company amended the lease for its corporate headquarters and primary research facility in Marlborough, Massachusetts. The lease is for a total of 7,581 square feet of office and laboratory space and will expire on March 31, 2024. The lease contains an option to terminate after two 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 was not included in the lease liability on the Company’s balance sheet. The Company did not exercise its option to terminate in either the second or third year of the lease, and the option to terminate has expired. Additionally, the lease agreement did not contain information to determine the borrowing 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.
The lease for the Company’s corporate headquarters represents all of ourits significant lease obligations. The amounts reported in the condensed consolidated balance sheets for the operating lease in which the Company is the lessee and other supplemental balance sheet information is set forth as follows, in thousands, except the lease term (number of years) and discount rate:

5. Preferred Stock
The Company has authorized up to shares of preferred stock, $ par value per share, for issuance. The Company’s Board of Directors (the “Board’) is authorized under the Company’s Amended and Restated Articles of Incorporation (as may be amended and/or restated from time to time, the “Amended Certificate”), to designate the authorized preferred stock into one or more series and to fix and determine such rights, preferences, privileges and restrictions of any series of preferred stock, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be determined by the Board upon its issuance.
On November 16, 2022, the Company issued and sold share of the Company’s Series D Preferred Stock, par value $0.0001$ per share (the “Series D Preferred Stock”) to Robert Bitterman, then its interim Executive Chairman and current Chief Executive Officer, for $1,750. The Series D Preferred Stock was entitled to 17,500,000 votes per share exclusively with respect to any proposal to amend the Company’s Amended Certificate to effect a reverse stock split of the Company’s common stock (“Reverse Stock Split”). The terms of the Series D Preferred Stock provided that it would be voted, without action by the holder, on any such proposal in the same proportion as shares of the Company’s common stock were voted. The Series D Preferred Stock otherwise had no voting rights except as required by the General Corporation Law of the State of Delaware.
The Series D Preferred Stock was not convertible into, or exchangeable for, shares of any other class or series of stock or other securities of the Company. The Series D Preferred Stock had no rights with respect to any distribution of assets of the Company, including upon a liquidation, bankruptcy, reorganization, merger, acquisition, sale, dissolution or winding up of the Company, whether voluntarily or involuntarily. The holder of the Series D Preferred Stock was not entitled to receive dividends of any kind.
Under its terms, the outstanding share of Series D Preferred Stock was to be redeemed in whole, but not in part, at any time: (i) if such redemption was approved by the Board in its sole discretion or (ii) automatically and effective upon the approval by the Company's stockholders of a Reverse Stock Split. Upon such redemption, the holder of the Series D Preferred Stock was entitled to receive consideration of $1,750 in cash.
The Series D Preferred Stock was redeemed in whole on January 4, 2023, upon the approval by the Company’s stockholders of a Reverse Stock Split, such that, at JuneSeptember 30, 2023, there were no shares of Series D Preferred Stock authorized, issued or outstanding and all of the Company’s authorized shares of preferred stock were undesignated.

6. Stockholders’ Equity
April 2023 Financing — On April 20, 2023, the Company completed a registered direct offering and a concurrent private placement of a total of: registered shares of the Company’s common stock at a purchase price per share of $, unregistered five and one-half year term Series A warrants to purchase up to shares of common stock at an exercise price of $5.40 per share and unregistered eighteen month term Series B warrants to purchase up to shares of common stock at an exercise price of $5.40 per share (collectively, the “April 2023 Financing”). In addition, the Company issued unregistered warrants to the placement agent, H.C. Wainwright & Co., LLC (“HCW”), in the April 2023 Financing to purchase a total of shares of common stock at an exercise price of $7.0625 per share. Net proceeds to the Company from the April 2023 Financing were $1,538,000 after deducting placement agent fees and offering expenses.
In connection with the April 2023 Financing, the Company entered into warrant amendment agreements (the “Warrant Amendment Agreements”) with the participating investors to amend the exercise price of certain existing warrants to purchase up to an aggregate of 191,619 shares of common stock that were previously issued in April 2018 through January 2021, such that each of the amended warrants have an exercise price of $5.40 per share. The Company received $24,000 as consideration in connection with the Warrant Amendment Agreements. The Company assessed the amendments to the exercise price of the warrants under the FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”) and determined that the amendment to the exercise price was completed in connection with and contingent on the close of the April 2023 Financing. The increase in fair value of $293,000 related to the Warrant Amendment Agreements was recognized as an equity issuance cost and recorded in additional paid in capital per ASC 815.
June 2023 Financing –— On June 2, 2023, the Company completed a registered direct offering and a concurrent private placement of a total of: registered shares and unregistered shares of the Company’s common stock each at a purchase price per share of $, unregistered pre-funded warrants to purchase up to an aggregate of shares of common stock at a purchase price per share of $ and with an exercise price of $0.001 per share, unregistered five and one-half year term Series A warrants to purchase up to an aggregate of shares of common stock at an exercise price of $4.03 per share and unregistered eighteen month term Series B warrants to purchase up to an aggregate of shares of common stock at an exercise price of $4.03 per share (collectively, the “June 2023 Financing”). In addition, the Company issued unregistered warrants to the placement agent, HCW, in the June 2023 Financing to purchase a total of shares of common stock at an exercise price of $5.35 per share. Net proceeds to the Company from the June 2023 Financing were $3,510,000 after deducting placement agent fees and offering expenses.
Warrants
The Company first assessed the warrants in the April 2023 Financing and June 2023 Financing under the FASB ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”) to determine whether they were within the scope of ASC 480. As there were no instances outside of the Company’s control that could require cash settlement, the Company’s warrants issued in the April 2023 Financing and June 2023 Financing were determined to be outside the scope of ASC 480.
The Company then applied and followed the applicable accounting guidance in the FASB ASC Topic 815 “Derivatives and Hedging..” Financial instruments are accounted for as either derivative liabilities or equity instruments depending on the specific terms of the agreement. The warrants issued in the April 2023 Financing and June 2023 Financing did not meet the definition of a derivative instrument as they are indexed to the Company’s common stock and classified within stockholders’ equity. Based on this determination, the warrants issued in the April 2023 Financing and June 2023 Financing were classified within stockholders’ equity.
During the sixthree and nine months ended JuneSeptember 30, 2023, shares of common stock issued related to exercises from the pre-funded warrants issued in the June 2023 Financing totaled . and , respectively. The Company realized proceeds of $175320 and $495, respectively, from the exercises of the pre-funded warrants. There were no warrants exercised during the sixthree and nine months ended JuneSeptember 30, 2022.

The Company’s outstanding warrants as of September 30, 2023 expire at various dates between October 2023 and December 2028.
In July 2023, the Company’s stockholders approved an amendment to the Company’s 2020 Long-Term Incentive Plan (the “2020 Plan”) to increase the number of shares authorized for issuance thereunder by shares.
Restricted Stock Units
Restricted stock units (“RSUs”) are issued under the Company’s 2020 Long-Term Incentive Plan (the “2020 Plan”) or as inducement grants issued outside of the 2020 Plan to new employees. RSUs are generally subject to graded vesting and the satisfaction of certain service requirements. Upon vesting, each outstanding RSU will be settled 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.
The following table summarizes the activity of the Company’s RSUs for the sixnine months ended JuneSeptember 30, 2023:

The aggregate fair value of awards that vested during the sixnine months ended JuneSeptember 30, 2023 and 2022 was $ and $, respectively, which represents the market value of the Company’s common stock on the date that the RSUs vested.
Stock Options
Stock options are available to be issued under the 2020 Plan and are generally subject to graded vesting and the satisfaction of certain 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 net share settle to satisfy stock option exercises.
The Company used 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 was 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 was based upon the Company’s own implied volatility. The expected life assumption used for option grants was based upon the simplified method provided for under the FASB ASC 718.Topic 718, “Compensation – Stock Compensation”. The dividend yield assumption was based upon the fact that the Company has never paid cash dividends and presently has no intention of paying cash dividends.

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted 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 the dilutive effect of potential common stock equivalents, except when the inclusion of such potential common stock equivalents would be anti-dilutive. Dilutive potential common stock equivalents primarily consist of stock options, RSUs and warrants. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented because the impact of these items is generally anti-dilutive during periods of net loss.
The weighted average number of common shares outstanding as of JuneSeptember 30, 2023 includes the pre-funded warrants issued in connection with the June 2023 Financing, the exercise of which requires nominal consideration for the delivery of the shares of common stock.
The following table sets forth the potential common shares excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive:

Overview
Phio is a clinical stage biotechnology company whose proprietary INTASYL™ self-delivering RNAi technology platform is designed to make immune cells more effective in killing tumor cells. We are developing therapeutics that are designed to leverage INTASYL to precisely target specific proteins that reduce the body’s ability to fight cancer, without the need for specialized formulations or drug delivery systems. Our efforts are focused on developing immuno-oncology therapeutics using our INTASYL platform. We have demonstrated preclinical efficacy in both direct-to-tumor injection and adoptive cell therapy (“ACT”) applications with our INTASYL compounds.
PH-762
PH-762 is an INTASYL compound designed to reduce the expression of cell death protein 1 (“PD-1”). PD-1 is a protein that inhibits T cells’ ability to kill cancer cells and is a clinically validated target in immunotherapy. Decreasing the expression of PD-1 can thereby increase the capacity of T cells, which protect the body from cancer cells and infections, to kill cancer cells.
| 15 |
PreclinicalOur preclinical studies conducted by the Company have demonstrated that direct-to-tumor application of PH-762 resulted in potent anti-tumoral effects and have shown that direct-to-tumor treatment with PH-762 inhibits tumor growth in a dose dependent fashion in PD-1 responsive and refractory models. Importantly, direct-to-tumor administration of PH-762 resulted in activity against distant untreated tumors, indicative of a systemic anti-tumor response. We believe these data further support the potential for PH-762 to provide a strong local immune response without the dose immune-related adverse effects seen with systemic antibody therapy.
In MayNovember 2023, we announced that the first patient dosed in our U.S. Food and Drug Administration (the “FDA”)multi-center Phase 1b clinical trial with PH-762 under a previously cleared our Investigational New Drug (“IND”) application to proceedby the Food and Drug Administration. Intratumoral injection of PH-762 in this dose-escalating trial will treat patients with a U.S. clinicalcutaneous squamous cell carcinoma, melanoma and Merkel cell carcinoma and is currently open for continued enrollment of patients. This trial of PH-762. The initial multi-center, dose-escalating, Phase 1b clinical trial under our cleared IND is designed to evaluate the safety and tolerability of neoadjuvant use of intratumorally injected PH-762, assess the tumor response, and determine the dose or dose range for continued study of PH-762. We plan to initiate our Phase 1b clinical trial of intratumoral PH-762 in patients with cutaneous squamous cell carcinoma, melanoma and Merkel cell carcinoma in the second half of 2023.
We intendGiven our intention to focus our efforts and resources on our U.S. clinical trial with PH-762, andwe have commencedcompleted the winding down process for our first-in-human clinical trial for PH-762 in France, which was limited to the treatment of patients with metastatic melanoma. Safety data from the initial cohort of three patients in the French clinical trial were evaluated by a data monitoring committee in the first quarter of 2023. The safety data review disclosed no dose-limiting toxicity, and no drug-related severe or serious adverse events.
Due to INTASYL’s ease of administration, we have shown that our compounds can easily be incorporated into current ACT manufacturing processes. In ACT, T cells are usually taken from a patient's own blood or tumor tissue, grown in large numbers in a laboratory, and then given back to the patient to help the immune system fight cancer. By treating T cells with our INTASYL compounds while they are being grown in the laboratory, we believe our INTASYL compounds can improve these immune cells to make them more effective in killing cancer. Preclinical data generated in collaboration with AgonOx, Inc. (“AgonOx”), a private company developing a pipeline of novel immunotherapy drugs targeting key regulators of the immune response to cancer, demonstrated that treating AgonOx’s “double positive” tumor infiltrating lymphocytes (“DP TIL”) with PH-762 increased their tumor killing activity by two-fold.
In March 2021, we entered into a clinical co-development collaboration agreement (the “Clinical Co-Development Agreement”) with AgonOx to develop a T cell-based therapy using PH-762 and AgonOx’s DP TIL. Under the Clinical Co-Development Agreement, we committed to provide financial support for development costs of up to $4 million to AgonOx for expenses incurred to conduct a Phase 1 clinical trial of PH-762 treated DP TIL in patients with advanced melanoma and other advanced solid tumors. Phio isWe are also eligible to receive certain future development milestones and low single-digit sales-based royalty payments from AgonOx’s licensing of its DP TIL technology. As of June 30, 2023, there is approximately $3,570,000 of remaining costs not yet incurred under the Clinical Co-Development Agreement.
PH-762 treated DP TIL are being evaluated in a Phase 1 clinical trial in the United States with up to 18 patients with advanced melanoma and other advanced solid tumors by our partner AgonOx. The primary trial objectives are to evaluate the safety and to study the potential for enhanced therapeutic benefit from the administration of PH-762 treated DP TIL. The Company announced the first patient was dosed in August 2023 and the trial is open for the continued enrollment of patients.
As of September 30, 2023, there is approximately $2,964,000 of remaining costs not yet incurred under the Clinical Co-Development Agreement.
PH-894
PH-894 is an INTASYL compound that is designed to silence BRD4, a protein that controls gene expression in both T cells and tumor cells, thereby effecting the immune system as well as the tumor. Intracellular and/or commonly considered “undruggable” targets, such as BRD4, represent a challenge for small molecule and antibody therapies. Therefore, what sets this compound apart is its dual mechanism: PH-894 suppression of BRD4 in T cells results in T cell activation, and suppression of BRD4 in tumor cells results in tumors becoming more sensitive to being killed by T cells.
| 16 |
Preclinical studies conducted have demonstrated that PH-894 resulted in a strong, concentration dependent and durable silencing of BRD4 in T cells and in various cancer cells. Similar to PH-762, preclinical studies have also shown that direct-to-tumor application of PH-894 resulted in potent and statistically significant anti-tumoral effects against distant untreated tumors, indicative of a systemic anti-tumor response. These preclinical data indicate that PH-894 can reprogram T cells and other cells in the tumor microenvironment to provide enhanced immunotherapeutic activity. We have completed the IND-enabling studies and are in the process of continuing to finalize the study reports required for an IND submission with PH-894. As a result of the reprioritization to advance our clinical trial with PH-762 in the U.S., we have elected to defer the IND submission for PH-894.
Critical Accounting Policies and Estimates
The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated 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 material changes to our critical accounting policies and estimates as compared to those disclosed in our 2022 Form 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 collaboration, 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. Since we commenced operations, research and development expenses have been a significant portion of our total operating expenses and are expected to constitute the majority of our spending for the foreseeable future.
Research and development expenses for the three months ended JuneSeptember 30, 2023 increased 6%decreased 28% as compared to the three months ended JuneSeptember 30, 2022. The increasedecrease in research and development expenses was primarily due to increased clinical-related costs of approximately $329,000 to support the two PH-762 Phase 1 clinical trials in the U.S., partially offset by decreased costs related to the completion of the Company’sour IND-enabling preclinical studies for PH-894 of approximately $207,000$1,515,000, partially offset by an increase in clinical-related costs of approximately $788,000 for our two U.S. PH-762 Phase 1 clinical trials as compared to the prior year period.
Research and development expenses for the sixnine months ended JuneSeptember 30, 2023 increased 22%decreased 1% as compared to the sixnine months ended JuneSeptember 30, 2022. The increasechange in research and development expenses was primarily due to increaseda decrease in costs related to the completion of our IND-enabling preclinical studies for PH-894 of approximately $1,562,000 and reduced lab supplies of approximately $218,000 as a result of a decrease in lab personnel, partially offset by an increase in clinical-related costs to support theof approximately $1,647,000 for our two U.S. PH-762 Phase 1 clinical trials in the U.S. of approximately $789,000, partially offset by decreased lab supply costs of $92,000 as a result of a change in headcount as compared to the prior year period.
We anticipate research and development expenses to continue to increase as a result of our clinical-related activities as our pipeline programs progress in clinical development.
General and Administrative Expenses
General and administrative expenses relate to compensation and benefits for general and administrative personnel, facility-related expenses, professional fees for legal and patent-related activities, audit, tax and consulting services, as well as other general corporate expenses.
General and administrative expenses for the three months ended JuneSeptember 30, 2023 decreased 4%9% as compared to the three months ended JuneSeptember 30, 2022. The decrease was primarily due to a total net reductionthe reduced use of business development consultants of approximately $28,000 in payroll-related expenses as a result of the changes in the Company’s Chief Executive Officer (“CEO”) position$73,000 as compared to the prior year period.
General and administrative expenses for the sixnine months ended JuneSeptember 30, 2023 increased 16%8% as compared to the sixnine months ended JuneSeptember 30, 2022. The increase in general and administrative expenses was primarily due to higher legal fees of approximately $378,000,$359,000 and audit fees of $62,000, partially offset by a total net reduction of approximately $52,000decreases in payroll-related expenses, as a resultincluding executive search-related fees, of theapproximately $190,000 due to changes in the Company’s CEO positionheadcount as compared to the prior year period.
Liquidity and Capital Resources
Historically, our primary source of funding has been through the sale of our 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. 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. At JuneSeptember 30, 2023, we had cash of $11,307,000$8,407,000 as compared with $11,781,000 at December 31, 2022.
| 18 |
During the quarterly periodnine months ended JuneSeptember 30, 2023, we completed the April 2023 Financing and June 2023 Financing (each as defined in Note 6 to our condensed consolidated interim financial statements) and received total net proceeds of $5,048,000 after deducting placement agent fees and offering expenses. For further information regarding the April 2023 Financing and June 2023 Financing, see Note 6 to our condensed consolidated interim financial statements included elsewhere in this Quarterly Report.
We have limited cash resources, have reported recurring losses from operations since inception and hashave not yet received product revenues. These factors raise substantial doubt regarding our ability to continue as a going concern, and our current cash resources may not provide sufficient capital to fund operations for at least the next 12 months from the date of the release of the financial statements included elsewhere in this Quarterly Report. Our continuation as a going concern depends upon our ability to raise additional capital through equity offerings, debt offerings and/or strategic opportunities to fund our operations. There can be no assurance that we will be successful in accomplishing any of these plans in order to continue as a going concern. The financial statements included elsewhere in this Quarterly Report do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

Net Cash Flow from Operating Activities
Net cash used in operating activities for the sixnine months ended JuneSeptember 30, 2023 decreased by 7%11% as compared to the sixnine months ended JuneSeptember 30, 2022, primarily due to decreased cash outflowoutflows from changes in operating assets and liabilities of $1,468,000$1,311,000 as a result of liabilities owed for the payments related to the IND-enabling studies with PH-894 and clinical supply manufacturing of PH-762 and PH-894 in the prior year period partially offset by an increase in net loss of $978,000.$182,000 and non-cash related items of $84,000.
Net Cash Flow from Investing Activities
Net cash used in investing activities for the sixnine months ended JuneSeptember 30, 2023 decreased 96% as compared to the sixnine months ended JuneSeptember 30, 2022, primarily due to changes in laboratory and computer equipment purchases for our facility over the comparative period.
Net Cash Flow from Financing Activities
Net cash provided by financing activities for the sixnine months ended JuneSeptember 30, 2023 increased as compared to the net cash used in financing activities for the sixnine months ended JuneSeptember 30, 2022, primarily due to the completion of the Company’sour April 2023 Financing and June 2023 Financing.

| ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK |
As a smaller reporting company, we are not required to provide this information.
| ITEM 4. | CONTROLS AND PROCEDURES |
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Principal Executive Officer (who is also acting as our Principal Financial Officer), evaluated the effectiveness of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange 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 Securities and Exchange Commission’s 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 Principal Executive Officer (who is also acting as our Principal Financial Officer), concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of such date.
Changes in Internal Control Over Financial Reporting
