<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Diffusion Pharmaceuticals Inc. (&#8220;Diffusion&#8221; or the &#8220;Company&#8221;), a Delaware corporation, is a clinical stage biotechnology company developing new treatments for life-threatening conditions by improving the body&#8217;s ability to bring oxygen to the areas where it is needed most. The Company is developing its lead product candidate, transcrocetinate sodium, also known as trans sodium crocetinate (&#8220;TSC&#8221;), for use in those life-threatening conditions in which cellular oxygen deprivation (&#8220;hypoxia&#8221;) is the basis for significant unmet medical needs. TSC is designed to safely and selectively target and re-oxygenate the micro-environment of hypoxic cells, with potential uses in many indications, including COVID-19, stroke, oncology, and cardiovascular disease.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The Company intends to begin first enrollment in Q3 2020 in its planned international TSC/COVID-19 program, designed to test TSC in a total of approximately 424 COVID-19 patients with symptoms of impaired respiratory function and low oxygen levels. Low oxygen levels are a frequent result of damage to the lungs, often leading to organ failure, the leading cause of death in COVID-19 patients. Diffusion believes TSC&#8217;s oxygen-enhancing mechanism could provide an important new treatment option.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">In stroke, TSC helps promote the diffusion of oxygen into those brain cells in which oxygen-deprivation causes neuronal death resulting in patient mortality or morbidity. In cancer, TSC re-oxygenates treatment-resistant cancerous tissue, making the cancer cells up to three times more susceptible to the therapeutic effects of standard-of-care radiation therapy and chemotherapy.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">In addition to the TSC programs, the Company is exploring alternatives regarding how best to capitalize upon our product candidate RES-529, which may include possible out-licensing and other options. RES-529 is a novel PI3K/Akt/mTOR pathway inhibitor which has completed two Phase 1 clinical trials for age-related macular degeneration and is in preclinical development in oncology, specifically GBM. RES-529 has shown activity in both in vitro and in vivo glioblastoma animal models and has been demonstrated to be orally bioavailable and capable of crossing the blood brain barrier.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The Company has not generated any revenues from product sales and has funded operations primarily from the proceeds of public and private offerings of equity, convertible debt and convertible preferred stock. Substantial additional financing will be required by the Company to continue to fund its research and development activities. No assurance can be given that any such financing will be available when needed or that the Company&#8217;s research and development efforts will be successful.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The Company regularly explores alternative means of financing its operations and seeks funding through various sources, including public and private securities offerings, collaborative arrangements with third parties and other strategic alliances and business transactions. The Company currently does not have any commitments to obtain additional funds and may be unable to obtain sufficient funding in the future on acceptable terms, if at all. If the Company cannot obtain the necessary funding, it will need to delay, scale back or eliminate some or all of its research and development programs or enter into collaborations with third parties to commercialize potential products or technologies that it might otherwise seek to develop or commercialize independently; consider other various strategic alternatives, including a merger or sale of the Company; or cease operations. If the Company engages in collaborations, it may receive lower consideration upon commercialization of such products than if it had not entered such arrangements or if it entered into such arrangements at later stages in the product development process.</p>

The length of time and cost of developing and commercializing these product candidates and/or failure of them at any stage of the drug approval process will materially affect the Company&#8217;s financial condition and future operations.

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:44pt;">The accompanying unaudited interim&nbsp;consolidated&nbsp;financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (&#8220;GAAP&#8221;) for interim financial information as found in the Accounting Standard Codification (&#8220;ASC&#8221;) and Accounting Standards Updates (&#8220;ASUs&#8221;) of the Financial Accounting Standards Board (&#8220;FASB&#8221;), and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the &#8220;SEC&#8221;). In the opinion of management, the accompanying&nbsp;unaudited interim consolidated financial statements of the Company include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the unaudited interim consolidated financial statements) considered necessary to present fairly the Company&#8217;s financial position as of&nbsp;June&nbsp;30, 2020, its results of operations for the three and six months ended June&nbsp;30, 2020 and 2019 and cash flows for the six months ended June&nbsp;30, 2020 and 2019. Operating results for the six months ended&nbsp;June&nbsp;30, 2020 are not necessarily indicative of the results that may be expected for the year ending December&nbsp;31, 2020. The unaudited interim&nbsp;consolidated&nbsp;financial statements presented herein do not contain the required disclosures under GAAP for annual financial statements. The accompanying&nbsp;unaudited interim consolidated&nbsp;financial statements should be read in conjunction with the annual audited financial statements and related notes as of and for the year ended December&nbsp;31, 2019 filed with the SEC on Form 10-K on March 17, 2020.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The preparation of the unaudited interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date the financial statements and reported amounts of expense during the reporting period. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and allowances, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19, governmental and business responses to the ongoing pandemic,&nbsp; further actions taken to contain or treat COVID-19 and the speed of the anticipated recovery, as well as the ongoing economic impact on local, regional, national and international markets. The COVID-19 pandemic had no material impact on our estimates and assumptions used in the preparation of the unaudited interim consolidated financial statements for the quarterly period ended June 30, 2020. Due to the uncertainty of factors surrounding these estimates or judgments, actual results may materially vary from our estimates. Estimates and assumptions are periodically reviewed, and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined.&nbsp; Our future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in material impacts to our consolidated financial statements in future reporting periods.&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company&#8217;s financial instruments, including cash equivalents and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic 820, <i>Fair Value Measurement</i>, for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in one of the following three categories:</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted net loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible debt, convertible preferred stock, common stock warrants, stock options and unvested restricted stock that would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are not included in the calculation as the impact is anti-dilutive.</p>

In addition, at the closing of the May 2020 Offering, the Company issued warrants to purchase up to 571,429 shares of common stock to designees of the placement agent for the May 2020 Offering.

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">On August 7, 2014, a complaint was filed in the Superior Court of Los Angeles County, California by Paul Feller, the Company&#8217;s former Chief Executive Officer under the caption&nbsp;<i>Paul Feller v. RestorGenex Corporation, Pro Sports &amp; Entertainment, Inc., ProElite, Inc. and Stratus Media Group, GmbH&nbsp;</i>(Case No. BC553996). The complaint asserts various causes of action, including, among other things, promissory fraud, negligent misrepresentation, breach of contract, breach of employment agreement, breach of the covenant of good faith and fair dealing, violations of the California Labor Code and common counts. The plaintiff is seeking, among other things, compensatory damages in an undetermined amount, punitive damages, accrued interest and an award of attorneys&#8217; fees and costs. On December 30, 2014, the Company filed a petition to compel arbitration and a motion to stay the action. On April 1, 2015, the plaintiff filed a petition in opposition to the Company&#8217;s petition to compel arbitration and a motion to stay the action. After a hearing for the petition and motion on April 14, 2015, the Court granted the Company&#8217;s petition to compel arbitration and a motion to stay the action. On January 8, 2016, the plaintiff filed an arbitration demand with the American Arbitration Association. On November 19, 2018 at an Order to Show Cause Re Dismissal Hearing, the Court found sufficient grounds not to dismiss the case, and an arbitration hearing has been scheduled for November 2020. The Company believes this matter is without merit and intends to defend the arbitration vigorously. Because this matter is in an early stage, the Company is unable to predict its outcome and the possible loss or range of loss, if any, associated with its resolution or any potential effect the matter may have on the Company&#8217;s financial position. Depending on the outcome or resolution of this matter, it could have a material effect on the Company&#8217;s financial position.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:8pt;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">We are a clinical stage biotechnology company developing new treatments for life-threatening conditions by improving the body&#8217;s ability to bring oxygen to the areas where it is needed most. We are developing our lead product candidate, transcrocetinate sodium, also known as trans sodium crocetinate (&#8220;TSC&#8221;), for use in those life-threatening conditions in which cellular oxygen deprivation (&#8220;hypoxia&#8221;) is the basis for significant unmet medical needs. TSC is designed to safely and selectively target and re-oxygenate the micro-environment of hypoxic cells, with potential uses in many indications, including COVID-19, stroke, oncology, and cardiovascular disease.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">In stroke, TSC helps promote the diffusion of oxygen into those brain cells in which oxygen-deprivation causes neuronal death resulting in patient mortality or morbidity. In cancer, TSC re-oxygenates treatment-resistant cancerous tissue, making the cancer cells up to three times more susceptible to the therapeutic effects of standard-of-care radiation therapy and chemotherapy. A range of tissue types, including both normal and cancerous cells, have been shown to be safely re-oxygenated in our preclinical and clinical studies using TSC&#8217;s novel mechanism of action.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">We believe TSC&#8217;s ability to re-oxygenate normal (i.e. non-cancerous) tissue that has become oxygen-deprived provides opportunities for new therapeutic approaches to conditions ranging from stroke and emergency medicine - including COVID-19 where multiple organ failure associated with Acute Respiratory Distress Syndrome (ARDS) is the leading cause of death - to cardiovascular and neurodegenerative diseases. In the treatment of cancerous tissue, we believe TSC&#8217;s therapeutic potential to lessen the tumor's treatment resistance to radiation and chemo-therapy is not limited to one specific tumor type, thereby making it potentially useful to improve standard-of-care treatments in many life-threatening cancers. Given TSC's safety profile and animal data, we could, with appropriate funding, move directly into Phase 2 studies for TSC in other cancers. The successful completion of trials for TSC or any other potential product candidate in these or any other indication is dependent upon our ability to further raise necessary capital.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">We believe that TSC has potential applications in stroke and emergency medicine. In stroke, a Phase 2 trial in cooperation with the University of California Los Angeles (UCLA) and the University of Virginia (UVA) to test TSC in the treatment of acute ischemic or hemorrhagic stroke is currently enrolling patients. Stroke is the 5th leading cause of death in the U.S. and the No. 1 cause of adult disability. Our stroke trial, which features in-ambulance dosing of TSC, is named the &#8220;PreHospital Acute Stroke Therapy - TSC&#8221; (PHAST - TSC) study, and is expected to enroll 160 patients, with 80 in the treatment arm and 80 in the control arm. We believe in-ambulance dosing of TSC will significantly cut the time in which the stroke-related oxygen deprivation to brain cells goes untreated, potentially leading to a better outcome for stroke victims treated in this manner. Near term enrollment in this trial is expected to be minimal for the duration of the COVID-19 pandemic.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Patients with COVID-19 infections are at risk for developing ARDS, which can lead to death from systemic hypoxemia (general lack of oxygen to body tissue and vital organs) and we believe&nbsp;that TSC&#8217;s oxygen-enhancing mechanism could provide an important new treatment option. Our TSC/Covid-19 clinical development program will begin with an open-label Phase 1b lead-in trial which, if successful, will be followed by one or more randomized double-blinded clinical trials powered for statistical significance. The lead-in will test TSC in 24 hospitalized COVID-19 patients at the Romanian National Institute of Infectious Diseases (NIID). We expect&nbsp;to begin dosing in this trial in the 3rd quarter of 2020 with data read-out in the fourth quarter of 2020. In addition to safety, the lead-in trial will collect data on possible increased oxygenation, thereby helping determine TSC dosing for follow-on studies.</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Assuming positive results for the lead-in trial and following regulatory approvals, we plan to begin a clinical trial program in the U.S. and Europe to study the safety and efficacy of TSC compared to placebo in a total of approximately 400 hospitalized COVID-19 patients. This clinical trial program will reflect the guidance received from both the US FDA and European regulatory agencies, with data availability presently targeted in about 18 months.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Our oncology program targets TSC against treatment-resistant brain cancer. A Phase 2 clinical program, completed in the second quarter of 2015, evaluated 59 patients with newly diagnosed glioblastoma multiforme (&#8220;GBM&#8221;), a particularly deadly form of primary brain cancer. GBM affects approximately 12,000 patients annually in the United States and approximately 35,000 patients annually worldwide. This open label, historically controlled study demonstrated a favorable safety and efficacy profile for TSC when combined with GBM&#8217;s standard of care, including a 37% improvement in overall survival over the control group at two years. A particularly strong efficacy signal was seen in the inoperable patients, where survival of TSC-treated patients at two years was increased by almost four-fold over the controls. In December 2017, we initiated the INvestigation of TSC Against Cancerous Tumors (INTACT) Phase 3 trial in the newly diagnosed inoperable GBM patient population. The trial is designed to enroll 236 patients in total, with 118 in the treatment arm and 118 in the control arm.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The trial began with an FDA-mandated open label 8 patient safety run-in for which enrollment has completed and is now closed. With the FDA&#8217;s permission, a total of 19 patients were enrolled to ensure that at least 8 complete data sets meeting the FDA&#8217;s specified 4-month exposure period would be available for review. The INTACT Trial Data Safety Monitoring Board (DSMB) met in the third quarter of 2019 and, based on their analysis, recommended that the study be continued. The DSMB concluded that no adverse safety signal had been observed, and unanimously recommended continuing the study as planned using the highest tested dose of TSC - 1.5 mg/kg - during the adjuvant treatment chemotherapy period with temozolomide. We believe that a preliminary efficacy signal was also received. A total of 10 patients were enrolled into the higher dose cohorts and 9 in the lower dose cohorts. In the higher dose patients, where the best results were expected, 3 discontinued treatment before meeting the FDA exposure period criteria. Of the 7 patients who met the criteria, 4 remain alive as of July 30, 2020. Commencement of enrollment in the randomization portion of the INTACT Phase 3 Trial is contingent upon our entering into a strategic partnership providing the necessary resources to undertake the full trial.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">In addition to the TSC programs, we are exploring alternatives regarding how best to capitalize upon our product candidate RES-529, which may include possible out-licensing and other options. RES-529 is a novel PI3K/Akt/mTOR pathway inhibitor which has completed two Phase 1 clinical trials for age-related macular degeneration and was in preclinical development in oncology, specifically GBM. RES-529 has shown activity in both in vitro and in vivo glioblastoma animal models and has been demonstrated to be orally bioavailable and capable of crossing the blood brain barrier.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The spread of COVID-19 during the first half of 2020 has caused an economic downturn on a global scale, as well as significant volatility in the financial markets. In March 2020 the World Health Organization declared COVID-19 a pandemic. We have experienced some disruptions to clinical operations, including with respect to patient enrollment in our clinical trials, specifically related to our stroke trial. In this time of uncertainty as a result of the COVID-19 pandemic, we have taken precautionary measures and adjusted our operational needs. We are continuing to conduct trials at certain clinical trial sites while taking precautions to provide a safe work environment for our trial participants and employees. However, some in-person visits are currently on hold and other activities are being conducted remotely to the extent possible. We have also made internal resource allocation decisions in order to deliver on key business objectives and to increase our financial flexibility, including, for example, pausing the development of certain preclinical research programs, delaying the start of certain longer-term clinical studies, limiting staff hiring and reducing the number of contract workers, and delaying or limiting information technology and facilities infrastructure projects. We may have to take further actions that we determine are in the best interests of our trial participants and employees or as required by federal, state, or local authorities.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">These changes will be reviewed based on future operating conditions and we will continue to take appropriate measures to address our changing needs. As the pandemic continues to unfold, the extent of the pandemic&#8217;s effect on our operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include changes in the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, and the resumption of widespread economic activity. Any prolonged material disruption on recruiting or retaining patients in our clinical trials, the ability of our suppliers to provide materials for our product candidates, or the regulatory review process could cause additional delays with respect to product development activities and could negatively impact our consolidated financial position, consolidated results of operations and consolidated cash flows.</p>

In consideration for the exercise of the Prior Warrants for cash and an additional $0.125 per each share of common stock underlying the Prior Warrant being exercised, the exercising investor received a new unregistered warrant to purchase up to an aggregate of 5,000,000 shares of common stock in a private placement. The warrant is exercisable immediately at an exercise price of $0.5263 per share and exercisable until November 8, 2025. In connection with the May 2020 investor warrant exercise, the Company issued 250,000 warrants to purchase shares of common stock to the placement agent with an exercise price of $0.5938 per share and which otherwise have identical terms to the warrants issued to the investor.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Research and development costs include, but are not limited to, third-party contract research arrangements, employee-related expenses, including salaries, benefits, stock-based compensation and travel expense reimbursement. Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As we advance our product candidates, we expect the amount of research and development costs will continue to increase for the foreseeable future. Research and development costs are charged to expense as incurred.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">We recognized $2.2 million in research and development expenses during the three months ended June 30, 2020 compared to $1.5 million during the three months ended June 30, 2019. The increase was attributable to a $0.6 million increase in costs associated with follow on work for our 19 patient run-in Phase 3 trial for GBM, a $0.3 million increase in expense related to our open-label Phase 1b lead-in trial for TSC in COVID-19 patients, and a $0.3 million increase in associated manufacturing costs as we ramp up the trial. These increases were offset in part by a $0.5 million decrease in costs associated with the delay in our Phase 2 stroke trial due to the COVID-19 pandemic.</p>

The increase in general and administrative expense was primarily due to a $0.3 million increase in professional fees and a $0.1 million increase in salaries, wages and other costs.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">We recognized $3.7 million in research and development expenses during the six months ended June&nbsp;30, 2020 compared to $3.2 million during the six months ended June&nbsp;30, 2019. The increase was attributable to $0.3 million in expense related to our open-label Phase 1b lead-in trial for TSC in COVID-19 patients, a $0.4 million increase in associated manufacturing expense as we ramp up the trial, and a $0.2 million increase in costs associated with follow on work for our 19-patient Phase 3 trial for GBM. These increases were offset in part by a $0.4 million decrease in costs associated with the delay in our Phase 2 stroke trial due to the COVID-19 pandemic.</p>

These amounts were offset by $0.3 million in stock-based compensation expense, and $0.1 million in depreciation expense.

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">We expect to continue to incur substantial expenses and generate significant operating losses as we continue to pursue our business strategy of developing our lead product candidate, TSC, for use in the treatment of hypoxia related indications. Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts of cash to advance the clinical development of our product candidates. At the current time, the bulk of our cash resources for clinical development is dedicated to the open-label Phase 1b lead-in trial for TSC in COVID-19 patients, and, to a lesser extent, the Phase 2 trial for TSC in acute stroke. While we believe we have adequate cash resources to continue operations into the fourth quarter of 2021, we will need to raise additional funds in order to complete these trials. We do not expect to commence any clinical trials beyond these trials unless we are able to raise additional capital, enter into strategic collaborations, or make alternative financing arrangements for any such trials. To date, we have funded our ongoing business operations and short-term liquidity needs, primarily through the sale and issuance of preferred stock, common stock and convertible debt. We expect to continue this practice for the foreseeable future, however, we may enter into strategic partnerships or transactions in order to fund our ongoing capital requirements.</p>

We may seek to raise additional funds through various sources, such as equity and debt financings, or through strategic collaborations and license agreements. We can give no assurances that we will be able to secure additional sources of funds to support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or be on terms acceptable to us or that potential delays in clinical trials due to the impact of COVID-19 could increase the anticipated cost of completing our clinical trials. This risk may increase if economic and market conditions deteriorate. If we are unable to obtain additional financing when needed, we may need to terminate, significantly modify or delay the development of our product candidates and our operations, or we may need to obtain funds through collaborators that may require us to relinquish rights to our technologies or product candidates that we might otherwise seek to develop or commercialize independently. If we are unable to raise any additional capital in the near-term and/or we cannot significantly reduce our expenses and are forced to terminate our operations, investors may experience a complete loss of their investment.</p>

Also, the Company&#8217;s outstanding warrants to purchase common stock, if exercised, will dilute the interests of our current stockholders. If we issue additional preferred stock or convertible debt securities, it could affect the rights of our common stockholders or reduce the value of our common stock or any outstanding classes of preferred stock. In particular, specific rights granted to future holders of preferred stock or convertible debt securities may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through strategic collaborations in the future, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses.</p>

We may, in some cases, use terms such as &#8220;believes,&#8221; &#8220;estimates,&#8221; &#8220;anticipates,&#8221; &#8220;expects,&#8221; &#8220;plans,&#8221; &#8220;intends,&#8221; &#8220;may,&#8221; &#8220;could,&#8221; &#8220;might,&#8221; &#8220;will,&#8221; &#8220;should,&#8221; &#8220;approximately&#8221; or other words that convey uncertainty of future events or outcomes to identify these forward-looking statements. Forward-looking statements appear in a number of places throughout this Quarterly Report and include statements regarding our intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things, our ongoing and planned preclinical development and clinical trials, the timing of and our ability to make regulatory filings and obtain and maintain regulatory and other approvals for our product candidates, our intellectual property position, our ability to maintain our Nasdaq listing, the degree of clinical utility of our products, particularly in specific patient populations, general business and market conditions, our ability to develop commercial functions, expectations regarding clinical trial data, our results of operations, the sufficiency of the Company&#8217;s cash, the Company&#8217;s need for and ability to obtain additional financing or partnering arrangements, financial condition, liquidity, prospects, growth and strategies, the industry in which we operate and the trends that may affect the industry or us.</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics and industry change, and depend on the economic circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report or incorporated by reference, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward-looking statements contained in this Quarterly Report or incorporated by reference. In addition, even if our results of operations, financial condition and liquidity, and the development of the industry in which we operate are consistent with the forward-looking statements contained in this Quarterly Report or incorporated by reference, they may not be predictive of results or developments in future periods.</p>

In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and we are required to apply our judgment in evaluating the cost-benefit relationship of possible internal controls. Our management evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered in this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of such period to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC&#8217;s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">The novel coronavirus (&#8220;COVID-19&#8221;) pandemic has resulted in significant financial market volatility, and its impact on the global economy and our operations remains uncertain. While we have business continuity plans in place to help mitigate the impact of COVID-19<u>[kcannavo1]</u>&nbsp;, a continuation or worsening of the pandemic could have a material adverse impact on our business, results of operations and financial condition and on the market price of our common stock.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">On March 12, 2020, the World Health Organization declared COVID-19 to be a pandemic. In an effort to contain and mitigate the spread of COVID-19, many countries worldwide have imposed quarantines, business closures and unprecedented restrictions on travel. The outbreak and government measures taken in response, have had a significant impact, both direct and indirect, on economic activity, as worker shortages have occurred, supply chains have been disrupted, facilities and production have been suspended and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services has fallen.</p>

<p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">As the pandemic continues, and if conditions worsen, [we expect to experience additional adverse effects on our operational activities and our financial condition. It is unclear which adverse effects may be material, and it remains uncertain the degree to which these adverse effects would impact our future operational activities and financial condition even if conditions begin to improve.] With the recent relaxation of restrictions on business operations and in-person gatherings there has been a resurgence in COVID-19 infections in numerous jurisdictions, resulting in the reinstatement of stricter restrictions and shutdowns. It is expected that there will be an ebb and flow to the pandemic with different jurisdictions having higher levels of infections than others over the course of the pandemic. In addition to existing travel restrictions, jurisdictions may continue or reinstate border closures, impose or reimpose prolonged quarantines and further restrict travel and business activity,</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">The COVID-19 pandemic has resulted in significant financial market volatility and uncertainty and continues to rapidly evolve. The extent to which the outbreak impacts our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others. A continuation or worsening of the levels of market disruption and volatility seen in the recent past could have an adverse effect on our ability to access capital, on our business, results of operations and financial condition, and on the market price of our common stock.</p>

<i><b>We face risks related to the planned clinical program to test TSC as a treatment for COVID-19</b></i><b>,&nbsp;</b><i><b>which has not been approved by the FDA or any other regulatory authority.</b></i></p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.2pt;text-align:left;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">In response to the recent global outbreak of COVID-19, on April 24, 2020, we submitted a Pre-IND to the FDA related to a planned clinical program using TSC in COVID-19 patients displaying severe respiratory symptoms and low oxygen levels, which received an accelerated review by the FDA under its Coronavirus Treatment Acceleration Program. We submitted our IND application for the COVID-19 clinical program on July 7, 2020, which incorporates pre-IND regulatory guidance from the FDA. Clinical trial start-up preparations are continuing as our IND submission is under review. The estimated timing of regulatory approval is based on factors beyond our control, including but not limited to, unforeseen scheduling difficulties and unfavorable results at various stages in the pre-market application process. This FDA approval or clearance process may be time-consuming and costly. Moreover, there is no guarantee that the IND submission will ultimately be acceptable to the FDA.&nbsp;Even if the IND&nbsp;is approved by&nbsp;the FDA, there can be no assurance as to when the FDA might provide such approved or when the program might be able to commence, if at all. We intend to work closely with the FDA to determine the best path forward to obtain approval, but we cannot guarantee that these efforts will be successful. Even if FDA approval for trials evaluating TSC for the treatment of ARDS is ultimately granted and we are able to move forward with clinical trials, such trials may entail significant additional time, effort and expense, particularly in light of the difficulty of doing business during the COVID-19 pandemic. In addition, there is no assurance of favorable results from any clinical trials, or that one or more of such trials will be completed in the currently anticipated timelines or at all. Further, we may make a strategic decision to discontinue clinical testing of TSC in COVID-19 patients, including in the event that other parties are successful in developing a more effective treatment for COVID-19.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.2pt;text-align:left;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">We have committed significant capital and resources to begin funding and supplying the clinical trials for the COVID-19 program. If we are unable to obtain regulatory approvals, or if clinical trials fail to demonstrate the clinical safety profile or the efficacy of TSC for the treatment of ARDS in COVID-19 patients, or if we make a strategic decision to discontinue testing TSC as a treatment for COVID-19 patients, we will be unable to recoup our significant expenses incurred to date and in the future related to the clinical program and the FDA approval process.</p>

Substantial additional financing will be required by the Company to continue to fund its research and development activities. &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No&lt;/div&gt; assurance can be given that any such financing will be available when needed or that the Company's research and development efforts will be successful.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;The Company regularly explores alternative means of financing its operations and seeks funding through various sources, including public and private securities offerings, collaborative arrangements with &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;third&lt;/div&gt; parties and other strategic alliances and business transactions. The Company currently does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have any commitments to obtain additional funds and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;be unable to obtain sufficient funding in the future on acceptable terms, if at all. If the Company cannot obtain the necessary funding, it will need to delay, scale back or eliminate some or all of its research and development programs or enter into collaborations with &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;third&lt;/div&gt; parties to commercialize potential products or technologies that it might otherwise seek to develop or commercialize independently; consider other various strategic alternatives, including a merger or sale of the Company; or cease operations. If the Company engages in collaborations, it &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;receive lower consideration upon commercialization of such products than if it had &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; entered such arrangements or if it entered into such arrangements at later stages in the product development process.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&amp;nbsp;&lt;/div&gt;   &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: center;"&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;Operations of the Company are subject to certain risks and uncertainties including various internal and external factors that will affect whether and when the Company's product candidates become approved drugs and how significant their market share will be, some of which are outside of the Company's control. The length of time and cost of developing and commercializing these product candidates and/or failure of them at any stage of the drug approval process will materially affect the Company's financial condition and future operations. The Company believes its cash and cash equivalents as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 30, 2020 &lt;/div&gt;are sufficient to fund operations into the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;fourth&lt;/div&gt; quarter of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dffn:LiquidityDisclosureTextBlock>

Expenditures to CROs represent a significant cost in clinical development for the Company. The Company could also enter into additional collaborative research, contract research, manufacturing, and supplier agreements in the future, which &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;require upfront payments and long-term commitments of cash.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: left; text-indent: 9pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Defined Contribution Retirement Plan&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;The Company has established a &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;401&lt;/div&gt;(k) defined contribution plan (the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&amp;#x201c;401&lt;/div&gt;(k) Plan&amp;#x201d;) that covers all employees who qualify under the terms of the plan. Eligible employees &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;elect to contribute to the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;401&lt;/div&gt;(k) Plan up to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;90%&lt;/div&gt; of their compensation, limited by the IRS-imposed maximum. The Company provides a safe harbor match with a maximum amount of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;4%&lt;/div&gt; of the participant's compensation. The Company made matching contributions under the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;401&lt;/div&gt;(k) Plan of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$14,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$20,000&lt;/div&gt; for the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 30, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019,&lt;/div&gt; respectively and matched approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$31,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$38,000&lt;/div&gt; during the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;six&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 30, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019,&lt;/div&gt; respectively.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;   &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: center;"&gt;&lt;/div&gt; &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: left; text-indent: 9pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Legal Proceedings&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 7, 2014, &lt;/div&gt;a complaint was filed in the Superior Court of Los Angeles County, California by Paul Feller, the Company's former Chief Executive Officer under the caption&amp;nbsp;&lt;div style="display: inline; font-style: italic;"&gt;Paul Feller v. RestorGenex Corporation, Pro Sports &amp;amp; Entertainment, Inc., ProElite, Inc. and Stratus Media Group, GmbH&amp;nbsp;&lt;/div&gt;(Case &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;BC553996&lt;/div&gt;). The complaint asserts various causes of action, including, among other things, promissory fraud, negligent misrepresentation, breach of contract, breach of employment agreement, breach of the covenant of good faith and fair dealing, violations of the California Labor Code and common counts. The plaintiff is seeking, among other things, compensatory damages in an undetermined amount, punitive damages, accrued interest and an award of attorneys' fees and costs. On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; December 30, 2014, &lt;/div&gt;the Company filed a petition to compel arbitration and a motion to stay the action. On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; April 1, 2015, &lt;/div&gt;the plaintiff filed a petition in opposition to the Company's petition to compel arbitration and a motion to stay the action. After a hearing for the petition and motion on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; April 14, 2015, &lt;/div&gt;the Court granted the Company's petition to compel arbitration and a motion to stay the action. On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; January 8, 2016, &lt;/div&gt;the plaintiff filed an arbitration demand with the American Arbitration Association. On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; November 19, 2018 &lt;/div&gt;at an Order to Show Cause Re Dismissal Hearing, the Court found sufficient grounds &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; to dismiss the case, and an arbitration hearing has been scheduled for &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; November 2020. &lt;/div&gt;The Company believes this matter is without merit and intends to defend the arbitration vigorously. Because this matter is in an early stage, the Company is unable to predict its outcome and the possible loss or range of loss, if any, associated with its resolution or any potential effect the matter &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;have on the Company's financial position. Depending on the outcome or resolution of this matter, it could have a material effect on the Company's financial position.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

Diluted net loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible debt, convertible preferred stock, common stock warrants, stock options and unvested restricted stock that would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are &lt;div style="display: inline;

Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company's financial instruments, including cash equivalents and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;820,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Fair Value Measurement&lt;/div&gt;, for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; of the following &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; categories:&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:center;"&gt;&amp;nbsp;&lt;/div&gt;

(&amp;#x201c;Diffusion&amp;#x201d; or the &amp;#x201c;Company&amp;#x201d;), a Delaware corporation, is a clinical stage biotechnology company developing new treatments for life-threatening conditions by improving the body's ability to bring oxygen to the areas where it is needed most. The Company is developing its lead product candidate, transcrocetinate sodium, also known as trans sodium crocetinate (&amp;#x201c;TSC&amp;#x201d;), for use in those life-threatening conditions in which cellular oxygen deprivation (&amp;#x201c;hypoxia&amp;#x201d;) is the basis for significant unmet medical needs. TSC is designed to safely and selectively target and re-oxygenate the micro-environment of hypoxic cells, with potential uses in many indications, including COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19,&lt;/div&gt; stroke, oncology, and cardiovascular disease.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;The Company intends to begin &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; enrollment in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;Q3&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; in its planned international TSC/COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; program, designed to test TSC in a total of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;424&lt;/div&gt; COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; patients with symptoms of impaired respiratory function and low oxygen levels. Low oxygen levels are a frequent result of damage to the lungs, often leading to organ failure, the leading cause of death in COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; patients. Diffusion believes TSC's oxygen-enhancing mechanism could provide an important new treatment option.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;In stroke, TSC helps promote the diffusion of oxygen into those brain cells in which oxygen-deprivation causes neuronal death resulting in patient mortality or morbidity. In cancer, TSC re-oxygenates treatment-resistant cancerous tissue, making the cancer cells up to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; times more susceptible to the therapeutic effects of standard-of-care radiation therapy and chemotherapy.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;In addition to the TSC programs, the Company is exploring alternatives regarding how best to capitalize upon our product candidate RES-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;529,&lt;/div&gt; which &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;include possible out-licensing and other options. RES-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;529&lt;/div&gt; is a novel &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;PI3K/Akt/mTOR&lt;/div&gt; pathway inhibitor which has completed &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt; Phase &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1&lt;/div&gt; clinical trials for age-related macular degeneration and is in preclinical development in oncology, specifically GBM.

The full extent to which the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and allowances, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;emerge concerning COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19,&lt;/div&gt; governmental and business responses to the ongoing pandemic,&amp;nbsp; further actions taken to contain or treat COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; and the speed of the anticipated recovery, as well as the ongoing economic impact on local, regional, national and international markets. The COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic had &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; material impact on our estimates and assumptions used in the preparation of the unaudited interim consolidated financial statements for the quarterly period ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 30, 2020. &lt;/div&gt;Due to the uncertainty of factors surrounding these estimates or judgments, actual results &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;materially vary from our estimates. Estimates and assumptions are periodically reviewed, and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined.&amp;nbsp; Our future assessment of the magnitude and duration of COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19,&lt;/div&gt; as well as other factors, could result in material impacts to our consolidated financial statements in future reporting periods.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt;   &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: center;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;DIFFUSION PHARMACEUTICALS INC.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: center;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:44pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: left;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Fair Value of Financial Instruments&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:8pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"&gt;Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company's financial instruments, including cash equivalents and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;820,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Fair Value Measurement&lt;/div&gt;, for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; of the following &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; categories:&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:center;"&gt;&amp;nbsp;&lt;/div&gt;

Diluted net loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible debt, convertible preferred stock, common stock warrants, stock options and unvested restricted stock that would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; included in the calculation as the impact is anti-dilutive.&lt;/div&gt; &lt;div style=" font-family: 'Times New Roman', Times, serif; font-size: 10pt;

The Company is developing its lead product candidate, transcrocetinate sodium, also known as trans sodium crocetinate (&#x201c;TSC&#x201d;), for use in those life-threatening conditions in which cellular oxygen deprivation (&#x201c;hypoxia&#x201d;) is the basis for significant unmet medical needs. TSC is designed to safely and selectively target and re-oxygenate the micro-environment of hypoxic cells, with potential uses in many indications, including COVID-<div style="display: inline; font-style: italic; font: inherit;">19,</div> stroke, oncology, and cardiovascular disease.</div> <div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</div> <div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The Company intends to begin <div style="display: inline; font-style: italic; font: inherit;">first</div> enrollment in <div style="display: inline; font-style: italic; font: inherit;">Q3</div> <div style="display: inline; font-style: italic; font: inherit;">2020</div> in its planned international TSC/COVID-<div style="display: inline; font-style: italic; font: inherit;">19</div> program, designed to test TSC in a total of approximately <div style="display: inline; font-style: italic; font: inherit;">424</div> COVID-<div style="display: inline; font-style: italic; font: inherit;">19</div> patients with symptoms of impaired respiratory function and low oxygen levels.

Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company's financial instruments, including cash equivalents and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic <div style="display: inline; font-style: italic; font: inherit;">820,</div> <div style="display: inline; font-style: italic;">Fair Value Measurement</div>, for financial assets and liabilities measured on a recurring basis.

On <div style="display: inline; font-style: italic; font: inherit;"> January 8, 2016, </div>the plaintiff filed an arbitration demand with the American Arbitration Association. On <div style="display: inline; font-style: italic; font: inherit;"> November 19, 2018 </div>at an Order to Show Cause Re Dismissal Hearing, the Court found sufficient grounds <div style="display: inline; font-style: italic; font: inherit;">not</div> to dismiss the case, and an arbitration hearing has been scheduled for <div style="display: inline; font-style: italic; font: inherit;"> November 2020. </div>The Company believes this matter is without merit and intends to defend the arbitration vigorously. Because this matter is in an early stage, the Company is unable to predict its outcome and the possible loss or range of loss, if any, associated with its resolution or any potential effect the matter <div style="display: inline; font-style: italic; font: inherit;"> may </div>have on the Company's financial position. Depending on the outcome or resolution of this matter, it could have a material effect on the Company's financial position.</div></div><span></span>

Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company's financial instruments, including cash equivalents and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments.

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>
