2017 Equity Incentive Plan

The Company’s 2017 Plan became effective in August 2017. Following the effective date of the Company's 2020 Plan (as defined below), the Company ceased granting awards under the 2017 Plan, however the terms and conditions of the 2017 Plan continue to govern any outstanding awards granted thereunder.

2020 Incentive Award Plan

The Company’s 2020 Plan was approved and became effective at the Company’s 2020 annual meeting of Shareholders on May 20, 2020 and unless, earlier terminated by the Board of Directors, will remain in effect until March 26, 2030. The 2020 Plan originally authorized for issuance the sum of (i) 911 shares of the Company’s common stock authorized for issuance and (ii) 233 shares of the Company’s common stock, which represents the number of shares that remained available for issuance under the 2017 Plan immediately prior to the approval of the 2020 Plan by the Company’s shareholders. Any shares of Common Stock under the 2017 Plan immediately prior to the approval of the 2020 Plan by the Company’s stockholders, that were subject to awards granted under the 2017 Plan that are forfeited or lapse unexercised and are not issued under the 2017 Plan will increase the number of shares of common stock available for grant under the 2020 Plan. In addition, the number of shares available for issuance under the 2020 Plan will increase on the first day of each calendar year beginning January 1, 2021 and ending on and including January 1, 2030 by a number of shares equal to the lesser of (A) 4% of the aggregate number of shares of the Company’s common stock outstanding on the final day of the immediately preceding calendar year and (B) such smaller number of shares of common stock as is determined by the Board of Directors. On January 1, 2021, the shares available for issuance under the 2020 Plan increased by 977 shares.

Options granted under the 2020 Plan have a term of ten years with the vesting schedule determined by the Board of Directors, which is generally four years.

As of March 31, 2021, there were 646 shares available to be granted under the 2020 Plan.

A summary of the status of the Company’s stock option activity for the three months ended March 31, 2021 is presented below (in thousands, except per share amounts):



	Number	Weighted Average
	of	Exercise
	Shares	Price per Share
Outstanding as of January 1, 2021	3,798	$	16.15
Granted	505	$	43.01
Forfeited	(17)	$	59.37
Exercised	(214)	$	3.97
Outstanding as of March 31, 2021	4,072	$	19.95

Options vested and exercisable as of March 31, 2021	2,192	$	2.81

As of March 31, 2021, the intrinsic value of options outstanding was $101,167. The intrinsic value for stock options is calculated based on the difference between the exercise prices of the underlying awards and the quoted stock price of the Company’s common stock as of the reporting date.

The total intrinsic value of stock options exercised for the three months ended March 31, 2021 and 2020 was $10,232 and $3,152, respectively.

The weighted average grant date fair value of options granted during the three months ended March 31, 2021 and 2020 was $33.24 and $11.97, respectively.

The weighted average grant date fair value of options vested at March 31, 2021 was $2.34.

The weighted average remaining contractual life is 6.7 years for options exercisable.

Stock-Based Compensation

The fair value of options granted during the three months ended March 31, 2021 and 2020 was estimated using the Black-Scholes option-pricing model with the following assumptions.


	For the						For the
	Three Months Ended						Three Months Ended
	March 31, 2021						March 31, 2020
Expected Term		5.50	years	-	6.25	years	6.25	years	-	6.25	years
Expected stock price volatility		95.00	%	-	98.00	%	79.02	%	-	80.54	%
Risk-free rate of interest		1.04	%	-	1.22	%	1.21	%	-	2.34	%
Expected dividend		0.0	%	-	0.0		0.0	%	-	0.0

Prior to the Company’s IPO, it did not have a history of market prices of its common stock and, as such, volatility was estimated using historical volatilities of similar public companies. In 2021, the Company began using a combination of the historical volatility of similar public companies and the limited historical information related to the Company’s common stock. The expected term of the employee awards is estimated based on the simplified method, which calculates the expected term based upon the midpoint of the term of the award and the vesting period. The Company uses the simplified method because it does not have sufficient option exercise data to provide a reasonable basis upon which to estimate the expected term. The expected dividend yield is 0% as the Company has no history of paying dividends nor does management expect to pay dividends over the contractual terms of these options. The risk-free interest rates are based on the United States Treasury yield curve in effect at the time of grant, with maturities approximating the expected term of the stock options.

Unrecognized compensation expense related to unvested awards as of March 31, 2021 was $35,099 and will be recognized over the remaining vesting periods of the underlying awards. The weighted-average period over which such compensation is expected to be recognized is 1.9 years.

Total stock-based compensation charges were approximately $5,565 and $776 for the three months ended March 31, 2021 and 2020, respectively. The Company charged $2,032 and $3,533 to research and development and general and administrative expense for the three months ended March 31, 2021, respectively. The Company charged $466 and $310 to research and development and general and administrative expense for the three months ended March 31, 2020, respectively.

2020 Employee Stock Purchase Plan

The Company’s 2020 Employee Stock Purchase Plan (the “ESPP”) was also approved and became effective at the Company’s 2020 annual meeting of Shareholders on May 20, 2020. The ESPP is designed to assist eligible employees of the Company with the opportunity to purchase the Company’s common stock at a discount through accumulated payroll deductions during successive offering periods. The aggregate number of Shares that may be issued pursuant to rights granted under the ESPP is 100 shares of common stock. In addition, the number of shares available for issuance under the ESPP will increase on the first day of each calendar year beginning on January 1, 2021 and ending on and including January 1, 2030 by a number of shares of common stock equal to the lesser of (a) 1% of the shares outstanding on the final day of the immediately preceding calendar year and (b) such smaller number of shares as determined by the Board. The number of shares that may be issued or transferred pursuant to rights granted under the component of the ESPP that is intended to qualify for favorable U.S. federal tax treatment under Section 423 of the Internal Revenue Code (the “Section 423 Component”) shall not exceed 500 shares. The purchase price will be determined by the administrator of the ESPP and, for purposes of the Section 423 Component, shall not be less than 85% of the fair market value of a share on the first trading day or on the last trading day of the applicable offering period, whichever is lower. On January 1, 2021, the shares available for issuance under the 2020 ESPP increased by 244 shares. To date, no shares have been sold under the ESPP.

Summary of Significant Accounting Policies	3 Months Ended
Summary of Significant Accounting Policies	Mar. 31, 2021
Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies Use of Estimates The preparation of our financial statements requires us to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity and expenses. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity and the amount of expenses. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of March 31, 2021, cash equivalents were comprised primarily of money market funds. Cash and cash equivalents held at financial institutions may at times exceed federally insured amounts. We believe we mitigate such risk by investing in or through major financial institutions. Property and Equipment Property and equipment are recorded at cost and depreciated and amortized over the shorter of their remaining lease term or their estimated useful life on a straight-line basis as follows: Equipment 3-5 years Furniture 7 years Leasehold improvements Lesser of life of improvement or lease term Expenditures for maintenance and repairs which do not improve or extend the useful lives of respective assets are expensed as incurred. When assets are sold or retired, the related cost and accumulated depreciation are removed from their respective accounts and any resulting gain or loss is include income (loss) from operations. The Company follows the guidance provided by the Financial Accounting Standards Board (“FASB”) ASC Topic 360‑10, Property, Plant, and Equipment. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future net cash flows expected to be generated. Impairment charges are recognized at the amount by which the carrying amount of an asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or the fair value less costs to sell. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our lease did not provide an implicit rate, we used an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any prepaid lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Renewal options were not included in our calculation of the related asset and liability. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718, “Compensation—Stock Compensation,” which requires the measurement and recognition of compensation expense based on estimated fair market values for all share-based awards made to employees, directors, and non-employees, including stock options. The Company’s 2017 Equity Incentive Plan (the “2017 Plan”) became effective in August 2017. The Company’s 2020 Incentive Award Plan (the “2020 Plan”) became effective in May 2020. Following the effective date of the Company's 2020 Plan, the Company ceased granting awards under the 2017 Plan, however the terms and conditions of the 2017 Plan continue to govern any outstanding awards granted thereunder. The Company’s stock option awards are valued at fair value on the date of grant and that fair value is recognized over the requisite service period. The estimated fair value of stock option awards was determined using the Black-Scholes option pricing model on the date of grant. Significant judgment and estimates were used to estimate the fair value of these awards, as they were not publicly traded. Stock awards granted by the Company subsequent to the IPO are valued using market prices at the date of grant. ASC 718 requires companies to estimate the fair value of share-based awards on the date of grant using an option-pricing model. The Black-Scholes option-pricing model was used as its method of determining fair value. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to, the expected stock price volatility over the term of the awards, and projected employee stock option exercise behaviors. The value of the award is recognized as an expense in the statement of operations over the requisite service period. The periodic expense is then determined based on the valuation of the options. The Company has elected to account for forfeitures as they occur, by reversing compensation cost when the award is forfeited. Research and Development Costs Research and development expenses include wages, benefits, facilities, supplies, external services, clinical study and manufacturing costs and other expenses that are directly related to the Company’s research and development activities. At the end of the reporting period, the Company compares payments made to third party service providers to the estimated progress toward completion of the research or development objectives. Depending on the timing of payments to the service providers and the progress that the Company estimates has been made as a result of the service provided, the Company may record net prepaid or accrued expense relating to these costs. Such estimates are subject to change as additional information becomes available. The Company expenses research and development costs as incurred. Expenses Accrued Under Contractual Arrangements As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. The majority of our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and contract research organizations that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing expenses, we estimate the time period over which services will be performed and the level of effort to be expended in each period, which is based on an established protocol specific to each clinical trial. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expense and expensed as incurred since recoverability of such expenditures is uncertain. Fair Value of Financial Instruments The Company applies the provisions of ASC 820, “Fair Value Measurements and Disclosures” for financial assets and liabilities measured on a recurring basis which requires disclosure that establishes a framework for measuring fair value. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources, or observable inputs, and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances, or unobservable inputs. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). ASC 820 requires that fair value measurements be classified and disclosed in one of three categories: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Directly or indirectly observable inputs as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument. Level 3: Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk in its assessment of fair value. The carrying amounts of cash and accounts payable approximate fair value due to the short-term nature of these instruments. As of March 31, 2021 and December 31, 2020, the Company had $189,572 and $212,562, respectively, in money market accounts (included in cash and cash equivalents) which was valued based on Level 1 inputs. There were no transfers between levels within the hierarchy during the three months ended March 31, 2021 and 2020. Earnings (Loss) per Share Basic earnings (loss) per share (“EPS”) is calculated in accordance with ASC 260, “Earnings Per Share,” by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and warrants. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future were not included in the computation of diluted EPS because to do so would have been antidilutive. Segment Information The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. To date, our chief operating decision maker has made such decisions and assessed performance at the company level as one segment. Recent Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic: 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU No. 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Key provisions include (i) the removal of separation models in ASC 470-20 for convertible instruments; (ii) expanded disclosures about the terms and features of convertible instruments; (iii) removed certain conditions for equity classification; and (iv) updated earnings per share calculation with respects to convertible instruments, share settlement presumption, down round features and the earnings per share denominator. ASU No. 2020-06 is effective for annual and interim reporting periods beginning after December 15, 2021, and the guidance is to be applied using the full or modified retrospective approach. Earlier adoption is permitted for annual and interim reporting periods beginning after December 15, 2020. The Company does not expect that the adoption of ASU No. 2020-06 will have a material impact on its financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) which amends the existing guidance relating to the accounting for income taxes. ASU No. 2019-12 is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of accounting for income taxes and to improve the consistent application of GAAP for other areas of accounting for income taxes by clarifying and amending existing guidance. ASU No. 2019-12 is effective for interim and annual periods beginning after December 15, 2020. The Company adopted ASU No. 2019-12 effective January 1, 2021. The adoption of ASU No. 2019-12 did not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. We adopted this standard effective January 1, 2020. ASU No. 2018-15 requires that certain implementation costs for cloud computing arrangements are capitalized and amortized over the term of associated hosted cloud computing arrangement service and that capitalized implementation costs are classified in prepaid expenses and other assets. ASO No. 2018-15 also provides classification guidance on these implementation costs as well as additional quantitative and qualitative disclosures. The adoption of ASU No. 2018-15 did not have an effect on the Company’s financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04 and ASU 2019-05 (collectively, “Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. Topic 326 was to be effective for reporting periods beginning after December 15, 2019, with early adoption permitted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) Effective Dates, which deferred the effective dates for the Company, until fiscal year 2023. The Company does not expect that the adoption of ASU No. 2016-13 will have a material impact on its financial statements.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2021
Summary of Significant Accounting Policies
Basis of Presentation	The accompanying unaudited financial statements do not include all of the information and footnotes required by GAAP. The accompanying year-end balance sheet was derived from audited financial statements but does not include all disclosures required by GAAP. The unaudited interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of March 31, 2021, the results of its operations for the three months ended March 31, 2021 and 2020 and its cash flows for the three months ended March 31, 2021 and 2020, respectively. The results for the three months ended March 31, 2021 are not necessarily indicative of results to be expected for the year ending December 31, 2021, any other interim periods or any future year or period. The accompanying unaudited financial statements of the Company should be read in conjunction with the audited financial statements and notes as of and for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on March 12, 2021. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements and notes thereto. The Company believes that its existing cash and cash equivalents will be sufficient to cover its cash flow requirements for at least the next twelve months from the issuance of these financial statements. However the Company’s future requirements may change and will depend on numerous factors.
Use of Estimates	Use of Estimates The preparation of our financial statements requires us to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity and expenses. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity and the amount of expenses.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of March 31, 2021, cash equivalents were comprised primarily of money market funds. Cash and cash equivalents held at financial institutions may at times exceed federally insured amounts. We believe we mitigate such risk by investing in or through major financial institutions.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and depreciated and amortized over the shorter of their remaining lease term or their estimated useful life on a straight-line basis as follows: Equipment 3-5 years Furniture 7 years Leasehold improvements Lesser of life of improvement or lease term Expenditures for maintenance and repairs which do not improve or extend the useful lives of respective assets are expensed as incurred. When assets are sold or retired, the related cost and accumulated depreciation are removed from their respective accounts and any resulting gain or loss is include income (loss) from operations. The Company follows the guidance provided by the Financial Accounting Standards Board (“FASB”) ASC Topic 360‑10, Property, Plant, and Equipment. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future net cash flows expected to be generated. Impairment charges are recognized at the amount by which the carrying amount of an asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or the fair value less costs to sell.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our lease did not provide an implicit rate, we used an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any prepaid lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Renewal options were not included in our calculation of the related asset and liability. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718, “Compensation—Stock Compensation,” which requires the measurement and recognition of compensation expense based on estimated fair market values for all share-based awards made to employees, directors, and non-employees, including stock options. The Company’s 2017 Equity Incentive Plan (the “2017 Plan”) became effective in August 2017. The Company’s 2020 Incentive Award Plan (the “2020 Plan”) became effective in May 2020. Following the effective date of the Company's 2020 Plan, the Company ceased granting awards under the 2017 Plan, however the terms and conditions of the 2017 Plan continue to govern any outstanding awards granted thereunder. The Company’s stock option awards are valued at fair value on the date of grant and that fair value is recognized over the requisite service period. The estimated fair value of stock option awards was determined using the Black-Scholes option pricing model on the date of grant. Significant judgment and estimates were used to estimate the fair value of these awards, as they were not publicly traded. Stock awards granted by the Company subsequent to the IPO are valued using market prices at the date of grant. ASC 718 requires companies to estimate the fair value of share-based awards on the date of grant using an option-pricing model. The Black-Scholes option-pricing model was used as its method of determining fair value. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to, the expected stock price volatility over the term of the awards, and projected employee stock option exercise behaviors. The value of the award is recognized as an expense in the statement of operations over the requisite service period. The periodic expense is then determined based on the valuation of the options. The Company has elected to account for forfeitures as they occur, by reversing compensation cost when the award is forfeited.
Research and Development Costs	Research and Development Costs Research and development expenses include wages, benefits, facilities, supplies, external services, clinical study and manufacturing costs and other expenses that are directly related to the Company’s research and development activities. At the end of the reporting period, the Company compares payments made to third party service providers to the estimated progress toward completion of the research or development objectives. Depending on the timing of payments to the service providers and the progress that the Company estimates has been made as a result of the service provided, the Company may record net prepaid or accrued expense relating to these costs. Such estimates are subject to change as additional information becomes available. The Company expenses research and development costs as incurred.
Expenses Accrued Under Contractual Arrangements	Expenses Accrued Under Contractual Arrangements As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. The majority of our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and contract research organizations that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing expenses, we estimate the time period over which services will be performed and the level of effort to be expended in each period, which is based on an established protocol specific to each clinical trial. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period.
Patent Costs	Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expense and expensed as incurred since recoverability of such expenditures is uncertain.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company applies the provisions of ASC 820, “Fair Value Measurements and Disclosures” for financial assets and liabilities measured on a recurring basis which requires disclosure that establishes a framework for measuring fair value. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources, or observable inputs, and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances, or unobservable inputs. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). ASC 820 requires that fair value measurements be classified and disclosed in one of three categories: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Directly or indirectly observable inputs as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument. Level 3: Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk in its assessment of fair value. The carrying amounts of cash and accounts payable approximate fair value due to the short-term nature of these instruments. As of March 31, 2021 and December 31, 2020, the Company had $189,572 and $212,562, respectively, in money market accounts (included in cash and cash equivalents) which was valued based on Level 1 inputs. There were no transfers between levels within the hierarchy during the three months ended March 31, 2021 and 2020.
Earnings (Loss) per Share	Earnings (Loss) per Share Basic earnings (loss) per share (“EPS”) is calculated in accordance with ASC 260, “Earnings Per Share,” by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and warrants. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future were not included in the computation of diluted EPS because to do so would have been antidilutive.
Segment Information	Segment Information The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. To date, our chief operating decision maker has made such decisions and assessed performance at the company level as one segment.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic: 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU No. 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Key provisions include (i) the removal of separation models in ASC 470-20 for convertible instruments; (ii) expanded disclosures about the terms and features of convertible instruments; (iii) removed certain conditions for equity classification; and (iv) updated earnings per share calculation with respects to convertible instruments, share settlement presumption, down round features and the earnings per share denominator. ASU No. 2020-06 is effective for annual and interim reporting periods beginning after December 15, 2021, and the guidance is to be applied using the full or modified retrospective approach. Earlier adoption is permitted for annual and interim reporting periods beginning after December 15, 2020. The Company does not expect that the adoption of ASU No. 2020-06 will have a material impact on its financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) which amends the existing guidance relating to the accounting for income taxes. ASU No. 2019-12 is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of accounting for income taxes and to improve the consistent application of GAAP for other areas of accounting for income taxes by clarifying and amending existing guidance. ASU No. 2019-12 is effective for interim and annual periods beginning after December 15, 2020. The Company adopted ASU No. 2019-12 effective January 1, 2021. The adoption of ASU No. 2019-12 did not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. We adopted this standard effective January 1, 2020. ASU No. 2018-15 requires that certain implementation costs for cloud computing arrangements are capitalized and amortized over the term of associated hosted cloud computing arrangement service and that capitalized implementation costs are classified in prepaid expenses and other assets. ASO No. 2018-15 also provides classification guidance on these implementation costs as well as additional quantitative and qualitative disclosures. The adoption of ASU No. 2018-15 did not have an effect on the Company’s financial statements.
