(&#x201c;Praxis&#x201d; or the &#x201c;Company&#x201d;) is a clinical-stage biopharmaceutical company translating insights from genetic epilepsies into the development of therapies for central nervous system ("CNS"), disorders characterized by neuronal excitation-inhibition imbalance. Normal brain function requires a delicate balance of excitation and inhibition in neuronal circuits, which, when dysregulated, can lead to abnormal function and both rare and more prevalent neurological disorders. The Company is applying genetic insights to the discovery and development of therapies for neurological disorders through two proprietary platforms, using its understanding of shared biological targets and circuits in the brain. Each platform has multiple programs currently, with significant potential for additional program and indication expansion: &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%;padding-left:14.5pt"&gt;Cerebrum&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2122;, the Company's small molecule platform, utilizes deep understanding of neuronal excitability and neuronal networks and applies a series of computational and experimental tools to develop orally available precision therapies &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%;padding-left:14.5pt"&gt;Solidus&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2122;, the Company's antisense oligonucleotide ("ASO"), platform, is an efficient, targeted precision medicine discovery and development engine anchored on a proprietary, computational methodology  &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company's platforms utilize a deliberate, pragmatic and patient-guided approach, leveraging a suite of translational tools, including novel transgenic and predictive translational animal models and electrophysiology markers, to enable an efficient path to proof-of-concept in patients.

The Company has funded its operations primarily with proceeds from the issuance of redeemable convertible preferred stock, from the sale of common stock through an initial public offering ("IPO"), at-the-market offerings under its shelf registration statement, and follow-on public offerings of common stock and pre-funded warrants to purchase common stock. From inception through December&#160;31, 2024, the Company raised $1.1&#160;billion in aggregate cash proceeds from these transactions, net of issuance costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company is subject to risks and uncertainties common to clinical-stage companies in the biotechnology industry, including but not limited to, risks associated with completing preclinical studies and clinical trials, receiving regulatory approvals for product candidates, development by competitors of new biopharmaceutical products, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Programs currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the Company&#x2019;s product development efforts are successful, it is uncertain when, if ever, the Company will realize revenue from product sales.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Liquidity&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2014-15, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Disclosure of Uncertainties about an Entity&#x2019;s Ability to Continue as a Going Concern (Subtopic 205-40)&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company&#x2019;s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company has incurred recurring losses since its inception, including a net loss of $182.8 million for the year ended December&#160;31, 2024. In addition, as of December&#160;31, 2024, the Company had an accumulated deficit of $836.7 million. The Company expects to continue to generate operating losses for the foreseeable future. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company expects that its cash, cash equivalents and marketable securities as of December&#160;31, 2024 of $469.5 million will be sufficient to fund its operating expenditures and capital expenditure requirements necessary to advance its research efforts and clinical trials for at least one year from the date of the issuance of these consolidated financial statements. The future viability of the Company is dependent on its ability to raise additional capital to finance its operations. The Company's inability to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. There can be no assurance that the current operating plan will be achieved or that additional funding will be available on terms acceptable to the Company, or at all.&lt;/span&gt;&lt;/div&gt;</us-gaap:NatureOfOperations>

money market funds and debt instruments of the U.S. Treasury, financial institutions, corporations and U.S. government agencies with strong credit ratings and an investment grade rating at or above A-1 or P-1 by two of the three nationally recognized statistical rating organizations. The Company does not believe that it is exposed to more than a nominal amount of credit risk related to any marketable securities it may invest in. The Company has established guidelines relative to diversification and maturities that maintain safety and liquidity, and periodically reviews and modifies these guidelines to maximize trends in yields and interest rates without compromising safety and liquidity. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company classifies its investments in debt instruments as available-for-sale. Available-for-sale investments are reported at fair value at each balance sheet date, and include any unrealized holding gains and losses in accumulated other comprehensive loss, a component of stockholders&#x2019; equity. Realized gains and losses are included in the Company's consolidated statements of operations. All of the Company's available-for-sale securities are available for use in its current operations. The Company classifies marketable securities as either cash equivalents, short-term or long-term based on their stated maturity dates as it is more-likely-than-not that the Company will hold these assets through to their maturity dates. The Company held $254.2 million of marketable securities as of December&#160;31, 2024. The Company did not hold any marketable securities as of December&#160;31, 2023.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company evaluates securities for impairment at the end of each reporting period. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include whether a decline in fair value below the amortized cost basis is due to credit-related factors or non-credit-related factors, the financial condition and near-term prospects of the Company, and the Company's intent and ability to hold the investment to allow for an anticipated recovery in fair value. A credit-related impairment is recognized as an allowance on the balance sheet with a corresponding adjustment to earnings. Any impairment that is not credit-related is recognized in other comprehensive loss, net of applicable taxes unless deemed other than temporary.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Concentrations of Credit Risk and Significant Suppliers and License Agreements&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash and marketable securities. The Company's investment portfolio may include money market funds, marketable debt securities, including debt securities issued by U.S. government agencies and corporations, and commercial paper. The Company's investments are limited to investment-grade securities with strong credit ratings with the objective of maintaining safety and liquidity. The Company also maintains deposits in accredited financial institutions in excess of federally insured limits. Bank accounts in the United States are insured by the Federal Deposit Insurance Corporation (the &#x201c;FDIC&#x201d;) up to $250,000. As of December&#160;31, 2024 and 2023, the Company&#x2019;s primary operating accounts significantly exceeded the FDIC limits. The Company deposits its cash in financial institutions that it believes have high credit quality, and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company is dependent on third-party manufacturers to supply materials for research and development activities of its programs, including preclinical and clinical testing. In particular, the Company relies, and expects to continue to rely, on a small number of third-party manufacturers to produce and process its current and potential product candidates and to manufacture supply of its current and potential product candidates for preclinical and clinical activities. These programs could be adversely affected by a significant interruption in the supply of the necessary materials. The Company is also dependent on third parties who provide license rights used in the development of certain programs. The Company could experience delays in the development of its programs if any of these license agreements are terminated, if the Company fails to meet the obligations required under its arrangements, or if the Company is unable to successfully secure new strategic alliances or licensing agreements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Off-Balance Sheet Risk&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As of December 31, 2024 and 2023, the Company had no off-balance sheet risk such as foreign exchange contracts, option contracts or other hedging arrangements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Fair Value Measurements&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Certain assets and liabilities of the Company are carried at fair value under GAAP. The fair values of the Company&#x2019;s financial assets and liabilities reflect the Company&#x2019;s estimate of the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 1: Quoted prices in active markets for identical assets or liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 2: Observable inputs (other than Level&#160;1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 3: Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level&#160;3. A financial instrument&#x2019;s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;An entity may choose to measure many financial instruments and certain other items at fair value at specified election dates. Subsequent unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Items measured at fair value on a recurring basis include cash equivalents and marketable securities (Note 4 and Note 5).

If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flows.

Operating lease right-of-use assets represent the Company&#x2019;s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating right-of-use assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term.

To the extent the arrangement is within the scope of ASC 808, the Company assesses whether aspects of the arrangement between the Company and its collaboration partner are within the scope of other accounting literature, including ASC Topic 606, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue from Contracts with Customers ("&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ASC 606"). If it is concluded that some or all aspects of the arrangement represent a transaction with a customer, the Company will account for those aspects of the arrangement within the scope of ASC 606.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ASC 808 provides guidance for the presentation and disclosure of transactions in collaborative arrangements, but it does not provide recognition or measurement guidance. Therefore, if the Company concludes a counterparty to a transaction is not a customer or otherwise not within the scope of ASC 606, the Company considers the guidance in other accounting literature as applicable or by analogy to account for such transaction. The classification of transactions under the Company&#x2019;s arrangements is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Revenue Recognition&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company enters into collaboration agreements which are within the scope of ASC 606 under which the Company may license or provide options to license certain development or product candidates and, in certain &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;cases, may perform research and development services.

To determine the appropriate amount of revenue to be recognized for agreements determined to be within the scope of ASC 606, the Company performs the following five steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations. The Company then assesses whether each promised good or service is distinct. When the Company offers options for additional goods or services, such as an option to obtain a license, it evaluates whether such options are material rights that should be treated as separate performance obligations. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. The consideration may include fixed consideration or variable consideration. At the inception of each agreement that includes variable consideration, the Company evaluates the amount of potential payments and the likelihood that the payments will be received to estimate the amount expected to be received. The amount of variable consideration included in the transaction price may be constrained and is included in the transaction price only to the extent that it is probable that a significant reversal of the cumulative revenue recognized will not occur in a future period.&lt;/span&gt;&lt;span style="color:#ff0000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company recognizes as revenue the amount of the transaction price that it allocated to the respective performance obligation when or as each performance obligation is satisfied, either at a point in time or over time. If the performance obligation is satisfied over time, the Company recognizes revenue based on the use of an output or input method. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. For example, f&lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;or research and development services that are recognized over time, the Company measures its progress using an input method. The input methods used are based on the effort the Company expends or costs it incurs toward the satisfaction of its performance obligation. The Company estimates the amount of effort it expends, including the time it estimates it will take to complete the activities, or costs it incurs in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that is multiplied by the transaction price to determine the amount of revenue recognized each period. If the estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that is recognized in the current and future periods.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Upfront payments are recorded as contract liabilities within deferred revenue on the consolidated balance sheets until the Company performs its obligations under these agreements.

Costs incurred to obtain licenses are recognized as research and development expense as incurred if the technology licensed has no alternative future uses.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company has entered into various research and development related contracts with parties both inside and outside of the United States. These agreements are cancellable, and related fees are recorded as research and development expenses as incurred. The Company records accrued liabilities and prepaid expenses for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities and prepaid expenses, the Company analyzes progress of the studies or clinical trials, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued and prepaid balances at the end of any reporting period. Actual results could differ from the Company&#x2019;s estimates. The Company&#x2019;s historical estimates have not been materially different from the actual costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Patent-Related Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Patent-related costs incurred in connection with patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure.

For stock-based awards issued to employees, non-employees and members of the Company&#x2019;s board of directors (the &#x201c;Board&#x201d;) for their services on the Board, the Company measures the estimated fair value of the stock-based award on the date of the grant. The Company recognizes compensation expense for those awards granted to employees and members of the Board over the requisite service period, which is generally the vesting period of the respective award. For non-employee awards, compensation expense is recognized as the services are provided, which is generally ratably over the vesting period. The Company issues stock-based awards with service-based vesting conditions and records the expense for these awards on a straight-line basis over the vesting period. To date, the Company has not issued any stock-based awards with performance or market-based vesting conditions. The Company accounts for forfeitures as they occur.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company classifies stock-based compensation expense in its consolidated statement of operations in the same manner in which the award recipient&#x2019;s salary or service payments are classified.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model, which requires inputs of subjective assumptions, including: (i)&#160;the expected volatility of the Company&#x2019;s stock; (ii)&#160;the expected term of the award; (iii)&#160;the risk-free interest rate; (iv)&#160;expected dividends; and (v)&#160;the fair value of common stock. Due to the lack of Company-specific historical and implied volatility data, the Company determines the volatility for awards granted based on an analysis of reported data for a group of guideline publicly-traded companies that issued options with substantially similar terms. For this analysis, the Company selects companies with comparable characteristics including enterprise value, risk profiles, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company determines expected volatility using a weighted average of the historical volatilities of the guideline group of companies. The Company expects to continue to apply this process until such time as it has adequate historical data regarding the volatility of its own traded stock price. As permitted under ASC 718, the Company has elected to use the contractual term as the expected term for certain non-employee awards, on an award-by-award basis. For all other awards, the expected term of the Company&#x2019;s stock options has been determined utilizing the &#x201c;simplified&#x201d; method whereby the expected term equals the average of the vesting term and the original contractual term of the option, on a weighted basis based on the vesting of each tranche. The Company utilizes this method as it has insufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for instruments with a term commensurate with the expected term assumption. The expected dividend yield is assumed to be zero &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;as the Company has never paid dividends, and does not have current plans to pay any dividends on its common stock. Subsequent to the IPO, the fair value of the common stock underlying the Company's stock-based awards is the closing price of the Company's common stock on the date of grant.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The grant date fair value of restricted stock units is estimated based on the fair value of the Company's underlying common stock on the date of grant.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Foreign Currency&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Monetary assets and liabilities resulting from transactions denominated in currencies other than the functional currency are remeasured into the functional currency at exchange rates prevailing at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currencies are measured using historical exchange rates prevailing at the date of the transaction and are not subsequently remeasured. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss. There were no material foreign currency gains or losses for the years ended December 31, 2024 and 2023.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Income Taxes&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent that it believes based upon the weight of available evidence it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company accounts for uncertain tax positions recognized in the consolidated financial statements by prescribing a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

The Company classifies warrants issued for the purchase of shares of its common stock as either equity or liability instruments based on an assessment of the specific terms and conditions of each respective contract. Such assessment includes determining whether the warrants are freestanding financial instruments or embedded in a host instrument, whether the warrants are liabilities within the scope of ASC 480, whether the warrants meet the definition of a derivative in ASC 815 and whether the warrants meet the requirements for equity classification pursuant to the indexation and equity classification criteria in ASC 815. The Company determines the classification for its warrants at the time of issuance and updates its assessment, as necessary. Warrants that meet all of the criteria for equity classification are recorded as a component of additional paid-in capital. Equity classified warrants are accounted for at fair value on the issuance date with no changes in fair value recognized after the issuance date.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Net Loss per Share&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period. The calculation of weighted average number of common shares outstanding excludes shares of restricted common stock that are not vested but includes shares of common stock underlying pre-funded warrants.

For purposes of this calculation, outstanding options to purchase shares of common stock, unvested shares of restricted common stock and potential shares issuable under the 2020 ESPP are considered potentially dilutive common shares. The Company has generated a net loss in all periods presented so the basic and diluted net loss per share are the same, as the inclusion of the potentially dilutive securities would be anti-dilutive.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Recent Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Recently Adopted Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In November 2023, the FASB issued ASU No. 2023-07,&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt; Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; ("ASU 2023-07").

The Company does not believe that it is exposed to more than a nominal amount of credit risk related to any marketable securities it may invest in. The Company has established guidelines relative to diversification and maturities that maintain safety and liquidity, and periodically reviews and modifies these guidelines to maximize trends in yields and interest rates without compromising safety and liquidity. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company classifies its investments in debt instruments as available-for-sale. Available-for-sale investments are reported at fair value at each balance sheet date, and include any unrealized holding gains and losses in accumulated other comprehensive loss, a component of stockholders&#x2019; equity. Realized gains and losses are included in the Company's consolidated statements of operations. All of the Company's available-for-sale securities are available for use in its current operations. The Company classifies marketable securities as either cash equivalents, short-term or long-term based on their stated maturity dates as it is more-likely-than-not that the Company will hold these assets through to their maturity dates. The Company held $254.2 million of marketable securities as of December&#160;31, 2024. The Company did not hold any marketable securities as of December&#160;31, 2023.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company evaluates securities for impairment at the end of each reporting period. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include whether a decline in fair value below the amortized cost basis is due to credit-related factors or non-credit-related factors, the financial condition and near-term prospects of the Company, and the Company's intent and ability to hold the investment to allow for an anticipated recovery in fair value. A credit-related impairment is recognized as an allowance on the balance sheet with a corresponding adjustment to earnings. Any impairment that is not credit-related is recognized in other comprehensive loss, net of applicable taxes unless deemed other than temporary.&lt;/span&gt;&lt;/div&gt;</us-gaap:MarketableSecuritiesPolicy>

The Company's investment portfolio may include money market funds, marketable debt securities, including debt securities issued by U.S. government agencies and corporations, and commercial paper. The Company's investments are limited to investment-grade securities with strong credit ratings with the objective of maintaining safety and liquidity. The Company also maintains deposits in accredited financial institutions in excess of federally insured limits. Bank accounts in the United States are insured by the Federal Deposit Insurance Corporation (the &#x201c;FDIC&#x201d;) up to $250,000. As of December&#160;31, 2024 and 2023, the Company&#x2019;s primary operating accounts significantly exceeded the FDIC limits. The Company deposits its cash in financial institutions that it believes have high credit quality, and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company is dependent on third-party manufacturers to supply materials for research and development activities of its programs, including preclinical and clinical testing. In particular, the Company relies, and expects to continue to rely, on a small number of third-party manufacturers to produce and process its current and potential product candidates and to manufacture supply of its current and potential product candidates for preclinical and clinical activities. These programs could be adversely affected by a significant interruption in the supply of the necessary materials. The Company is also dependent on third parties who provide license rights used in the development of certain programs. The Company could experience delays in the development of its programs if any of these license agreements are terminated, if the Company fails to meet the obligations required under its arrangements, or if the Company is unable to successfully secure new strategic alliances or licensing agreements.&lt;/span&gt;&lt;/div&gt;</us-gaap:ConcentrationRiskCreditRisk>

The fair values of the Company&#x2019;s financial assets and liabilities reflect the Company&#x2019;s estimate of the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 1: Quoted prices in active markets for identical assets or liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 2: Observable inputs (other than Level&#160;1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;padding-left:45pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 3: Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level&#160;3. A financial instrument&#x2019;s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;An entity may choose to measure many financial instruments and certain other items at fair value at specified election dates. Subsequent unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Items measured at fair value on a recurring basis include cash equivalents and marketable securities (Note 4 and Note 5). The carrying amounts reflected in the consolidated balance sheets for cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.&lt;/span&gt;&lt;/div&gt;</us-gaap:FairValueMeasurementPolicyPolicyTextBlock>

Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant &lt;/span&gt;&lt;/div&gt;negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flows.</us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock>

To the extent the arrangement is within the scope of ASC 808, the Company assesses whether aspects of the arrangement between the Company and its collaboration partner are within the scope of other accounting literature, including ASC Topic 606, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue from Contracts with Customers ("&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ASC 606").

To determine the appropriate amount of revenue to be recognized for agreements determined to be within the scope of ASC 606, the Company performs the following five steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations. The Company then assesses whether each promised good or service is distinct. When the Company offers options for additional goods or services, such as an option to obtain a license, it evaluates whether such options are material rights that should be treated as separate performance obligations. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. The consideration may include fixed consideration or variable consideration. At the inception of each agreement that includes variable consideration, the Company evaluates the amount of potential payments and the likelihood that the payments will be received to estimate the amount expected to be received. The amount of variable consideration included in the transaction price may be constrained and is included in the transaction price only to the extent that it is probable that a significant reversal of the cumulative revenue recognized will not occur in a future period.&lt;/span&gt;&lt;span style="color:#ff0000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company recognizes as revenue the amount of the transaction price that it allocated to the respective performance obligation when or as each performance obligation is satisfied, either at a point in time or over time. If the performance obligation is satisfied over time, the Company recognizes revenue based on the use of an output or input method. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. For example, f&lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;or research and development services that are recognized over time, the Company measures its progress using an input method. The input methods used are based on the effort the Company expends or costs it incurs toward the satisfaction of its performance obligation. The Company estimates the amount of effort it expends, including the time it estimates it will take to complete the activities, or costs it incurs in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that is multiplied by the transaction price to determine the amount of revenue recognized each period. If the estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that is recognized in the current and future periods.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Upfront payments are recorded as contract liabilities within deferred revenue on the consolidated balance sheets until the Company performs its obligations under these agreements.

For stock-based awards issued to employees, non-employees and members of the Company&#x2019;s board of directors (the &#x201c;Board&#x201d;) for their services on the Board, the Company measures the estimated fair value of the stock-based award on the date of the grant. The Company recognizes compensation expense for those awards granted to employees and members of the Board over the requisite service period, which is generally the vesting period of the respective award. For non-employee awards, compensation expense is recognized as the services are provided, which is generally ratably over the vesting period. The Company issues stock-based awards with service-based vesting conditions and records the expense for these awards on a straight-line basis over the vesting period. To date, the Company has not issued any stock-based awards with performance or market-based vesting conditions. The Company accounts for forfeitures as they occur.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company classifies stock-based compensation expense in its consolidated statement of operations in the same manner in which the award recipient&#x2019;s salary or service payments are classified.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model, which requires inputs of subjective assumptions, including: (i)&#160;the expected volatility of the Company&#x2019;s stock; (ii)&#160;the expected term of the award; (iii)&#160;the risk-free interest rate; (iv)&#160;expected dividends; and (v)&#160;the fair value of common stock. Due to the lack of Company-specific historical and implied volatility data, the Company determines the volatility for awards granted based on an analysis of reported data for a group of guideline publicly-traded companies that issued options with substantially similar terms. For this analysis, the Company selects companies with comparable characteristics including enterprise value, risk profiles, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company determines expected volatility using a weighted average of the historical volatilities of the guideline group of companies. The Company expects to continue to apply this process until such time as it has adequate historical data regarding the volatility of its own traded stock price. As permitted under ASC 718, the Company has elected to use the contractual term as the expected term for certain non-employee awards, on an award-by-award basis. For all other awards, the expected term of the Company&#x2019;s stock options has been determined utilizing the &#x201c;simplified&#x201d; method whereby the expected term equals the average of the vesting term and the original contractual term of the option, on a weighted basis based on the vesting of each tranche. The Company utilizes this method as it has insufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for instruments with a term commensurate with the expected term assumption. The expected dividend yield is assumed to be zero &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;as the Company has never paid dividends, and does not have current plans to pay any dividends on its common stock. Subsequent to the IPO, the fair value of the common stock underlying the Company's stock-based awards is the closing price of the Company's common stock on the date of grant.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The grant date fair value of restricted stock units is estimated based on the fair value of the Company's underlying common stock on the date of grant.&lt;/span&gt;&lt;/div&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Such assessment includes determining whether the warrants are freestanding financial instruments or embedded in a host instrument, whether the warrants are liabilities within the scope of ASC 480, whether the warrants meet the definition of a derivative in ASC 815 and whether the warrants meet the requirements for equity classification pursuant to the indexation and equity classification criteria in ASC 815.

its marketable securities classified as Level 2 by taking into consideration valuations obtained from third-party pricing sources. These pricing sources utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include market pricing based on real-time trade data for the same or similar securities, issuer credit spreads, benchmark yields, and other observable inputs. The Company validates the prices provided by its third-party pricing sources by understanding the models used, obtaining market values from other pricing sources and analyzing pricing data in certain instances.&lt;/span&gt;&lt;/div&gt;</us-gaap:FairValueDisclosuresTextBlock>

Under the terms of the Collaboration Agreement, the Company has agreed to perform general biology-related research services as part of a mutually agreed upon research plan in exchange for a $5.0 million upfront payment. In addition, the Company provided UCB an exclusive option to in-license global development and commercialization rights to any resulting KCNT1 small molecule development candidate identified as part of the research plan. If UCB exercises its option to in-license global development and commercialization rights, the Collaboration Agreement stipulates that UCB will assume research, development, manufacturing and commercialization responsibilities and costs. Under the terms of the Collaboration Agreement, the Company will be eligible to receive an option fee and future success-based development and commercialization milestone payments, totaling up to $98.5 million, in addition to tiered royalties on net sales of any resulting products from the Collaboration Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company concluded that UCB is a customer, and as such, the arrangement falls within the scope of Topic 606. At the commencement of the Collaboration Agreement, the Company identified one performance obligation, which was to perform the research services for UCB. The Company determined the transaction price to be $5.0&#160;million, comprised of the upfront payment it received. The option provided to UCB was determined not to be a material right. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company recognizes revenue for its research services performance obligation over time using an input method over the duration of the research services. In December 2024, UCB exercised its option to in-license global development and commercialization rights for a KCNT1 development candidate as part of the Collaboration Agreement. Upon notice of the exercise, the Company recognized the $6.0 million option exercise fee as collaboration revenue within the consolidated statement of operations. The Company also recognized the $2.6 million of remaining collaboration revenue associated with the $5.0&#160;million up front payment, as the Company will have no further research service obligations under the terms of the Collaboration Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;During the years ended December 31, 2024 and 2023, the Company recognized $8.6 million and $2.4 million respectively, in collaboration revenue related to the Collaboration Agreement in the consolidated statement of operations. As of December&#160;31, 2024, there was no deferred revenue included in the consolidated balance sheet.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Tenacia Collaboration and License Agreement&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On January 4, 2024, the Company entered into an exclusive collaboration and license Agreement (&#x201c;the License Agreement&#x201d;) with Tenacia, a China-based portfolio company of Bain Capital, which provides Tenacia an exclusive license to use certain intellectual property for the development and commercialization of ulixacaltamide and products containing ulixacaltamide in China, Hong Kong, Macau and Taiwan. Tenacia is solely responsible for the development and commercialization under the arrangement, with the exception of the associated manufacturing. The Company also entered into a Stock Purchase Agreement (&#x201c;the Stock Purchase Agreement&#x201d;) with BCPE Tenet Holdings Cayman, Ltd. (&#x201c;BCPE&#x201d;), a related party of Tenacia. Pursuant to the terms of the License Agreement, the Company was entitled to an up-front, non-refundable and non-creditable cash payment of $5.0 million, net of certain tax withholdings. In addition, the Company is eligible to receive $264.0 million in success-based development and commercialization milestone payments as well as tiered royalties on net sales. Pursuant to the terms of the Stock Purchase Agreement, the Company issued and sold 443,253 shares of its common stock to BCPE at a price per share of $22.5605 for aggregate gross proceeds of $10.0 million. The per share price was based on a 20% premium over the 30-day volume-weighted average price.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Under the terms of the License Agreement, the Company granted to Tenacia an exclusive license to use certain intellectual property for the development and commercialization of ulixacaltamide and products containing ulixacaltamide in China, Hong Kong, Macau and Taiwan.

Total proceeds associated with the combined arrangement at inception were $14.8 million consisting of the following: (i) $10.0&#160;million gross proceeds from the sale of common stock under the Stock Purchase Agreement and (ii) $4.8 million, net of tax, related to the up-front payment under the License Agreement, both of which were received in January 2024.   During the year ended December&#160;31, 2024, the Company had not achieved any development or sales milestones or earned any royalties under the License Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company recorded the common stock sold to BCPE at its issuance date fair value of $38.95 per share, or $17.3 million in the aggregate, which exceeded the proceeds received which were calculated based on the 20% premium over the prior 30-day volume-weighted average price. Accordingly, there is no transaction price allocable to the performance obligation. The Company accounted for the excess of the fair value of the equity securities issued over the total proceeds received as consideration paid to a customer for which no distinct good or service was transferred in exchange.  As a result, the transaction gives rise to negative revenue on a cumulative basis in the amount of $2.5 million, which was recorded at the inception of the collaboration and license agreement in research and development expense in the accompanying consolidated statement of operations. For agreements where the licenses are considered separate performance obligations or represent the only performance obligation, the Company recognizes revenue at the point in time that the Company effectively grants the license, as the licenses or assignments represent functional intellectual property.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As of December&#160;31, 2024, the Company did not have any receivables or deferred revenue related to the arrangement with Tenacia. The Company did not recognize any contract assets related to costs to obtain a contract with a customer or costs to fulfill a contract with a customer through December&#160;31, 2024 because no qualifying costs were incurred. During the year ended December&#160;31, 2024, the Company did not recognize any revenue associated with the combined arrangement.&lt;/span&gt;&lt;/div&gt;</us-gaap:CollaborativeArrangementDisclosureTextBlock>

Further, the Company determined that the pre-funded warrants do not meet the definition of a derivative under ASC 815 because they do not meet the criteria regarding no or little initial net investment. Accordingly, the Company assessed the pre-funded warrants relative to the guidance in ASC No. 815-40, &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contracts in Entity&#x2019;s Own Equity&lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, to determine the appropriate treatment.

The Company did not recognize an income tax benefit in the years ended December&#160;31, 2024 or 2023 related to its U.S. operations due to the uncertainty regarding future taxable income. In the years ended December 31, 2024 and 2023, the difference between the statutory tax rate in the U.S. and the Company&#x2019;s effective tax rate was due primarily to the valuation allowance recorded to offset any potential tax benefit. The income tax benefit (provision) recognized for the years ended December 31, 2024 and 2023 was not material.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New

Federal net operating loss carryforwards of $7.7 million will expire at various dates from 2035 through 2037 and approximately $334.7 million may be carried forward indefinitely.&#160;As of December 31, 2024 and 2023, the Company also had state net operating loss carryforwards of approximately $289.7 million and $239.4 million, respectively, which may be available to offset future income tax liabilities and expire at various dates from 2036 through 2044.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As of December 31, 2024 and 2023, the Company had federal research and development tax credit carryforwards of approximately $27.3 million and $20.4 million, respectively, available to reduce future tax liabilities which expire at various dates from 2039 through 2044.&#160;As of December 31, 2024 and 2023, the Company had state research and development tax credit carryforwards of approximately $4.1 million and $3.8 million, respectively, available to reduce future tax liabilities which expire at various dates from 2032 through 2039.&#160;The Company has generated research credits but has not conducted a study to document the qualified activity.&#160;This study may result in an adjustment to the Company&#x2019;s research and development credit carryforwards; however, until a study is completed, and any adjustment is known, no amounts are being presented as an uncertain tax position.&#160;A full valuation allowance has been provided against the Company&#x2019;s research and development credits and, if an adjustment is required, this adjustment would be offset by an adjustment to the deferred tax asset established for the research and development credit carryforwards and the valuation allowance.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Under the provisions of the Internal Revenue Code, the net operating loss and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities.&#160;Net operating loss and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change.&#160;Subsequent ownership changes may further affect the limitation in future years. The Company has not conducted a study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study.&#160;If the Company has experienced a change of control, as defined by Section&#160;382, at any time since inception, utilization of &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;the net operating loss carryforwards or research and development tax credit carryforwards would be subject to an annual limitation under Section&#160;382, which is determined by first multiplying the value of the Company&#x2019;s stock at the time of the ownership change by the applicable long-term tax-exempt rate, and then could be subject to additional adjustments, as required. Any limitation may result in expiration of a portion of the net operating loss carryforwards or research and development tax credit carryforwards before utilization. Further, until a study is completed by the Company and any limitation is known, no amounts are being presented as an uncertain tax position.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:24.75pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After consideration of all of the evidence, both positive and negative, the Company has recorded a valuation allowance against its deferred tax assets at December 31, 2024 and 2023 because management has determined that it is more likely than not that the Company will not recognize the benefits of its federal and state deferred tax assets, primarily due to its history of cumulative net losses incurred since inception and its lack of commercialization of any products or generation of any revenue from product sales since inception. As a result, a valuation allowance of $218.3 million and $180.5 million has been established at December 31, 2024 and 2023, respectively.&#160;Management reevaluates the positive and negative evidence at each reporting period. The valuation allowance increased by approximately $37.8 million and $36.6 million during the years ended December 31, 2024 and 2023, respectively, due primarily to the generation of net operating losses.&lt;/span&gt;&lt;/div&gt;The Company has not recorded any amounts for unrecognized tax benefits as of December 31, 2024 and 2023.&#160;The Company&#x2019;s policy is to record interest and penalties related to uncertain tax positions as part of its income tax provision.&#160;As of December 31, 2024 and 2023, the Company had no accrued interest or penalties related to uncertain tax positions and no such amounts have been recognized in the Company&#x2019;s consolidated statement of operations for either year ended December&#160;31, 2024 or 2023.&#160;The statute of limitations for federal and the majority of state tax authorities is open for tax years ended December&#160;31, 2021 through December&#160;31, 2024. The statute of limitation for the remaining state tax authorities is open for tax years ended December&#160;31, 2020 through December&#160;31, 2024. Since the Company is in a net loss carryforward position, the Company is generally subject to examination by the U.S. federal, state and local income tax authorities for all tax years in which a loss carryforward is available.</us-gaap:IncomeTaxDisclosureTextBlock>

The operating segment's revenue is derived from a single domestic collaboration agreement from which the segment licenses certain development or product candidates and has performed research and development services. The measure of segment assets is reported on the balance sheet as total consolidated assets.
