You should read the following discussion and analysis of our financial condition and results of operations together with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and the audited financial information and the notes thereto included in our Annual Report on Form 10-K, which was filed with theSecurities and Exchange Commission (the "SEC") onFebruary 28, 2022 . Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the "Risk Factors" section of our Annual Report on Form 10-K for the year endedDecember 31, 2021 and set forth in the "Risk Factors" section of this Quarterly Report on Form 10-Q, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Insight
We are a clinical-stage biopharmaceutical company translating genetic insights into the development of therapies for central nervous system, or 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 disease. We are applying insights from genetic epilepsies to both rare and more prevalent neurological and psychiatric disorders, using our understanding of shared biological targets and circuits in the brain. We apply a deliberate and pragmatic precision 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. Through this approach, we have established a broad CNS portfolio with multiple programs, including product candidates across psychiatric disorders, movement disorders and epilepsy, with three clinical-stage product candidates. Each of our clinical-stage product candidates is advancing in more than one indication and we anticipate expansion into additional indications. We expect multiple topline readouts from our clinical-stage programs and anticipate the launch of two additional clinical development programs this year. In addition, we have established a robust pipeline of preclinical stage programs through internal research and in-licensing. Our broad portfolio of CNS programs is currently structured by therapeutic focus in three franchises - Psychiatry, Movement Disorders and Epilepsy. Within our Psychiatry franchise, our most advanced clinical candidate,PRAX -114, is being developed for the treatment of a broad range of patients suffering from major depressive disorder, or MDD, and post-traumatic stress disorder, or PTSD. We have completed the Aria Study, a Phase 2/3, placebo-controlled study evaluatingPRAX -114 for monotherapy treatment of MDD, and expect to report topline results inJune 2022 . Following topline results from the Aria Study, we intend to engage with theU.S. Food and Drug Administration , or FDA, for an end-of-Phase 2 meeting and subsequently initiate a Phase 3, placebo-controlled study in the fourth quarter of 2022. We also expect to report topline results from the Acapella Study, a Phase 2, placebo-controlled, dose-ranging study evaluatingPRAX -114 for treatment of MDD, in the third quarter of 2022. In addition, we expect to report topline results from a Phase 2, placebo-controlled study evaluatingPRAX -114 for the treatment of PTSD in the second half of 2022. Within our Movement Disorders franchise, our second clinical candidate,PRAX -944, is being developed for the treatment of Essential Tremor, or ET, and Parkinson's Disease, or PD. InMay 2022 , we reported positive topline results from the second cohort of our Phase 2a trial evaluatingPRAX -944 for the treatment of ET. We expect to report topline results from the Phase 2b placebo-controlled Essential1 Study for daytime treatment of ET in the second half of 2022. Following the topline results from the second cohort, Part B, of the Phase 2a study ofPRAX -944 for the treatment of ET, we intend to change the primary endpoint of the Essential1 Study from safety to efficacy. We also initiated a Phase 2, placebo-controlled, crossover study to evaluate the safety, pharmacokinetics, or PK, and efficacy of daytime dosing ofPRAX -114 for the treatment of ET in the first quarter of 2022 and expect to report topline results in the second half of 2022. In addition, the FDA cleared the Investigational New Drug, or IND, submission for a Phase 2 study ofPRAX -944 for the treatment of PD. We intend to initiate a Phase 2, placebo-controlled trial to evaluate the safety, PK and efficacy ofPRAX -944 as a non-dopaminergic treatment for the motor symptoms of PD in the second half of 2022. Within our Epilepsy franchise, we expect to initiate a Phase 2, placebo-controlled study with our third clinical-stage candidate,PRAX -562, in the second half of 2022 for the treatment of rare pediatric Developmental and Epileptic Encephalopathies. Our most advanced preclinical stage product candidate within our Epilepsy franchise, 14 --------------------------------------------------------------------------------PRAX -222, is an antisense oligonucleotide, or ASO, designed to decrease the expression levels of the protein encoded by the gene SCN2A in patients with gain-of-function SCN2A mutations. InApril 2022 , we announced that we received an email communication from the FDA that our IND application for the first-in-patient study ofPRAX -222 was place on clinical hold. The letter detailing the reasons for the hold is expected to be received from the FDA within 30 days ofApril 28, 2022 . We expect to initiate a Phase 1 study with our preclinical candidate,PRAX -628, in the fourth quarter of 2022 and subsequently initiate a Phase 2 study in focal epilepsy in 2023. Our preclinical pipeline also consists of discovery programs in development for KCNT1 related epilepsy, three ASOs targeting SCN2A in patients with loss-of-function mutations, PCDH19 and SYNGAP1, respectively, and three additional discovery programs for undisclosed targets in psychiatry, movement disorders and epilepsy. We plan to declare ASO candidates forPRAX -080 for PCDH19 andPRAX -090 for SYNGAP1 in 2023. We were incorporated in 2015 and commenced operations in 2016. Since inception, we have devoted substantially all of our resources to developing our preclinical and clinical product candidates, building our intellectual property, or IP, portfolio, business planning, raising capital and providing general and administrative support for these operations. We employ a "virtual" research and development model, relying heavily upon external consultants, collaborators and contract research organizations, or CROs, to conduct our preclinical and clinical activities. Since inception, we have financed our operations primarily with proceeds from the sale and issuance of equity securities. We are a development stage company and we have not generated any revenue from product sales, and do not expect to do so for several years, if at all. All of our product candidates are still in preclinical and clinical development. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our product candidates, if approved. We have incurred recurring operating losses since inception, including a net loss of$68.7 million for the three months endedMarch 31, 2022 . As ofMarch 31, 2022 , we had an accumulated deficit of$385.3 million . We expect to incur significant expenses and operating losses for the foreseeable future as we expand our research and development activities. In addition, our losses from operations may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenditures on other research and development activities. We anticipate that our expenses will be maintained or increased in connection with our ongoing activities, as we:
• advancing our lead product candidates,
• advancing our
• advancing our
•take our preclinical candidates to clinical trials;
•invest more in our pipeline;
•invest more in our manufacturing capabilities;
• seek regulatory approval for our product candidates;
•maintain, develop, protect and defend our intellectual property portfolio;
•acquire or license technology;
•take temporary precautionary measures to help minimize the risk of COVID-19 to our employees; and
•increase our workforce to support our development efforts and expand our clinical development team.
In addition, as we progress toward potential marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates or delay our pursuit of potential in-licenses or acquisitions. 15 -------------------------------------------------------------------------------- Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations. As ofMarch 31, 2022 , we had cash, cash equivalents and marketable securities of$222.5 million . We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our operating expenses and capital expenditures into the third quarter of 2023. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See "-Liquidity and Capital Resources."
COVID-19 Business Update
In light of the ongoing COVID-19 pandemic, we continue to experience some disruptions and increased risk in our operations and those third parties upon whom we rely. These include disruptions and risks related to the conduct of our clinical trials and preclinical studies as policies at various clinical sites and federal, state, local and foreign laws, rules and regulations continue to evolve, including quarantines, travel restrictions and redirection of healthcare resources toward pandemic response efforts. The COVID-19 pandemic has impacted the enrollment of some of our ongoing clinical trials, including slower patient enrollment and treatment in some of our clinical studies, the impact of which has varied by clinical study and program, but none of which have significantly impacted our overall clinical trial timelines. While we have experienced limited financial impacts to date, given the global economic slowdown, the overall disruption of global healthcare systems and the other risks and uncertainties associated with the pandemic such as increased inflation, our business, financial condition and results of operations could be materially adversely affected. We continue to closely monitor the COVID-19 pandemic as we evolve our business continuity plans, clinical development plans and response strategy. Financial Operations Overview Revenue We have not generated any revenue since inception and do not expect to generate any revenue from the sale of products for several years, if at all. If our development efforts for our current or future product candidates are successful and result in marketing approval or collaboration or license agreements with third parties, we may generate revenue in the future from a combination of product sales or payments from such collaboration or license agreements.
Functionnary costs
Research and development costs
The nature of our activities and the main orientation of our activities generate a significant amount of research and development costs. Research and development expenses represent the costs we incur to:
•costs of developing our portfolio;
•discovery efforts leading to the development of candidates;
•the costs of clinical development of our product candidates; and
•the costs of developing our manufacturing technology and infrastructure.
The above costs include the following categories:
•personnel expenses, including salaries, benefits and stock-based compensation expenses;
•expenses incurred under agreements with third parties, such as consultants, investigative sites and CROs, that conduct our preclinical and clinical studies and in-licensing arrangements;
•costs incurred to maintain compliance with regulatory requirements;
16 --------------------------------------------------------------------------------
•costs incurred with third party development and contract manufacturing organizations to acquire, develop and manufacture materials for preclinical and clinical studies; and
•depreciation, amortization and other direct and allocated expenses, including rent, insurance and other operating costs, incurred as a result of our research and development activities. We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors and our clinical investigative sites. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our consolidated balance sheets as prepaid expenses or accrued expenses. Non-refundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized, even when there is no alternative future use for the research and development. The capitalized amounts are expensed as the related goods are delivered or the services are performed. As a company operating in a virtual environment, a significant portion of our research and development costs have been external costs. We track direct external research and development expenses to specific franchises and product candidates upon commencement. Due to the number of ongoing studies and our ability to use resources across several projects, indirect or shared operating costs incurred for our research and development franchises, such as personnel, facility costs and certain consulting costs, are not recorded or maintained on a franchise-specific basis. The following table reflects our research and development expenses, including direct expenses summarized by major franchise and other exploratory CNS indications and indirect or shared operating costs recognized as research and development expenses during each period presented (in thousands): Three Months Ended March 31, 2022 2021 Psychiatry$ 14,438 $ 3,201 Epilepsy 14,264 4,926 Movement disorders 9,104 1,577 Other exploratory CNS indications 2,191 663 Personnel-related (including stock-based compensation) 11,141 6,505 Other indirect research and development expenses 1,514 1,057 Total research and development expenses $
52,652
Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will continue to increase in the foreseeable future as we advance our product candidates through the development phase, and as we continue to discover and develop additional product candidates, build manufacturing capabilities and expand into additional therapeutic areas. At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from sales or licensing of our product candidates. This is due to the numerous risks and uncertainties associated with drug development, including the uncertainty of:
•our ability to recruit and retain key research and development personnel;
•the timing and progress of preclinical and clinical development activities;
•the number and scope of preclinical and clinical programs that we decide to pursue;
17 --------------------------------------------------------------------------------
• our ability to successfully complete clinical trials with satisfactory safety, tolerability and efficacy profiles for the
• our ability to successfully develop, obtain regulatory approval and then successfully commercialize our product candidates;
• our successful enrollment and completion of clinical trials;
•costs associated with the development of any additional product candidates that we identify internally or acquire through collaborations;
• our ability to discover, develop and use biomarkers to demonstrate target engagement, pathway engagement and impact on disease progression of our product candidates;
•our ability to establish and maintain agreements with third-party manufacturers for clinical supply for our clinical trials and commercial manufacturing, if our product candidates are approved;
• the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder;
• our ability to obtain and maintain patent, trade secret and other intellectual property protection and regulatory exclusivity for our product candidates, if approved;
• our receipt of marketing approvals from applicable regulatory authorities;
• our ability to commercialize products, if approved, alone or in conjunction with others; and
•the maintenance of acceptable safety profiles of candidate products after approval.
A change in any of these variables with respect to the development of any of our product candidates would significantly change the costs, timing and viability associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect, or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time to complete our clinical development activities. We may never obtain regulatory approval for any of our product candidates. Drug commercialization will take several years and require significant development costs.
General and administrative costs
General and administrative expenses consist primarily of personnel-related costs, including salaries, benefits and stock-based compensation, for personnel in our executive, finance, legal, commercial and administrative functions. General and administrative expenses also include legal fees relating to corporate matters; professional fees for accounting, auditing, tax and administrative consulting services; commercial-related costs to support market assessments and scenario planning; insurance costs; administrative travel expenses; and facility-related expenses, which include direct depreciation costs and allocated expenses for office rent and other operating costs. These costs relate to the operation of the business, unrelated to the research and development function, or any individual franchises or product candidate. Costs to secure and defend our IP are expensed as incurred and are classified as general and administrative expenses. We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support the expected growth in our research and development activities and the potential commercialization of our product candidates. We also expect to incur additional IP-related expenses as we file patent applications to protect innovations arising from our research and development activities.
Other income
Other income, net
Other income, net, includes interest income from our cash, cash equivalents and marketable securities and amortization of premiums and investment discounts.
18 --------------------------------------------------------------------------------
Income taxes
Since our inception, we have not recorded anyU.S. federal or state income tax benefits for the net losses we have incurred in each year or for our earned research and development tax credits due to our uncertainty of realizing a benefit from those items. Income taxes are determined at the applicable tax rates adjusted for non-deductible expenses, research and development tax credits and other permanent differences. Our income tax provision may be significantly affected by changes to our estimates. The income tax benefit (provision) for the three months endedMarch 31, 2022 and 2021 was not material.

Cash and capital resources
Sources of liquidity
Since our inception, we have incurred significant losses in each period. We have not yet commercialized any of our product candidates, which are in various phases of preclinical and clinical development, and we do not expect to generate revenue from sales of any products for several years, if at all. To date, we have financed our operations primarily with proceeds from the sale and issuance of equity securities. From inception throughMarch 31, 2022 , we have raised$517.8 million in aggregate cash proceeds from such transactions, net of issuance costs. As ofMarch 31, 2022 , we had cash, cash equivalents and marketable securities of$222.5 million . OnNovember 3, 2021 , we entered into an Open Market Sale Agreement, or the sales agreement, withJefferies LLC , or Jefferies, to provide for the offering, issuance and sale of up to an aggregate amount of$125.0 million of common stock from time to time in at-the-market offerings for which Jefferies acts as sales agent. During the three months endedMarch 31, 2022 , we issued and sold 70,410 shares under the sales agreement for aggregate net proceeds of$1.4 million . We have issued and sold a total of 462,407 shares under the sales agreement for aggregate net proceeds of$8.4 million after deducting commissions and offering expenses payable by us.

Net decrease in cash, cash equivalents and restricted cash
Operational activities
Our cash flows from operating activities are greatly influenced by our use of cash for operating expenses and working capital requirements to support our business. We have historically experienced negative cash flows from operating activities as we have invested in developing our portfolio, drug discovery efforts and related infrastructure. 20 -------------------------------------------------------------------------------- The cash used in operating activities resulted primarily from our net losses adjusted for non-cash charges and changes in operating assets and liabilities, which are primarily the result of increased expenses and timing of vendor payments. During the three months endedMarch 31, 2022 , net cash used in operating activities of$54.1 million was primarily due to our$68.7 million net loss, partially offset by$8.5 million of non-cash charges primarily related to stock-based compensation, and$6.1 million in changes in operating assets and liabilities primarily related to increases in accounts payable and accrued expenses. During the three months endedMarch 31, 2021 , net cash used in operating activities of$25.7 million was primarily due to our$27.4 million net loss and$3.5 million in changes in operating assets and liabilities primarily related to a decrease in accrued expenses and prepaid expenses and other current assets, partially offset by$5.1 million of non-cash charges primarily related to stock-based compensation.

Operation plan and future financing needs
We expect our expenses to increase substantially in connection with our ongoing research and development activities, particularly as we advance the preclinical activities and clinical trials of our product candidates. As a result, we expect to incur substantial operating losses and negative operating cash flows for the foreseeable future. We anticipate that our expenses will increase substantially if and as we:
•advance the clinical development of our clinical-stage product candidates within our psychiatry, movement disorders and epilepsy franchises, respectively;
•advance the development of any additional product candidates;
•conduct research and pursue the preclinical development of potential product candidates;
•make strategic investments in manufacturing capabilities;
•maintain our intellectual property portfolio and opportunistically acquire additional intellectual property;
•seeking regulatory approvals for our product candidates;
•potentially establish a sales, marketing and distribution infrastructure and scale-up manufacturing capabilities to commercialize any products for which we may obtain regulatory approval; •add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support our product development and potential future commercialization efforts and to support our operations as a public company; and
• experiencing delays or experiencing issues with any of the above, including but not limited to failed studies, complex results, safety issues or other regulatory challenges.
We are unable to estimate the exact amount of our working capital requirements, but based on our current operating plan, we believe that our existing cash, cash equivalents and marketable securities will enable us to fund 21 --------------------------------------------------------------------------------
our operating expenses and capital expenditure requirements through the third quarter of 2023. However, we have based this estimate on assumptions that may prove to be inaccurate and we may deplete our capital resources sooner than expected.
Because of the numerous risks and uncertainties associated with product development and potential collaborations with third parties for the development of our product candidates, we may incorrectly estimate the timing and amounts of increased capital outlays and operating expenses associated with completing the research and development of our product candidates. Our funding requirements and timing and amount of our operating expenditures will depend on many factors, including, but not limited to:
•the extent, progress, results and costs of preclinical studies and clinical trials of our franchises and product candidates;
•the number and characteristics of product candidates and technologies that we develop or may license;
•the costs and timing of future commercialization activities, including manufacturing, marketing, sales and distribution, for each of our product candidates for which we receive marketing authorization;
•the costs necessary to obtain regulatory approvals, if any, for products inthe United States and other jurisdictions, and the costs of post-marketing studies that could be required by regulatory authorities in jurisdictions where approval is obtained;
• the costs and delays of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any claims related to intellectual property;
•the continuation of our existing license agreements and the entry into new collaborations and license agreements;
•the costs we incur to maintain our business operations;
•the costs associated with being a public company;
•revenues, if any, from commercial sales of any product candidates for which we receive marketing authorization;
•the effect of competing technological and commercial developments;
•the impact of any business interruptions to our operations or to those of our manufacturers, suppliers or other vendors resulting from the COVID-19 pandemic or similar public health crisis; and •the extent to which we acquire or invest in businesses, products and technologies, including entering into licensing or collaboration arrangements for product candidates, although we currently have no commitments or agreements to complete any such acquisitions or investments in businesses. Identifying potential product candidates and conducting preclinical testing and clinical trials is a time consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for many years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives. Adequate additional funds may not be available to us on acceptable terms, or at all. We do not currently have any committed external source of funds. Market volatility resulting from the COVID-19 pandemic or other factors could also adversely impact our ability to access capital as and when needed. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of holders of our common stock. Additional debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends and may require the issuance of warrants, which could potentially result in dilution to the holders of our common stock. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional 22 --------------------------------------------------------------------------------
funds through equity or debt financings if necessary, we may be required to delay, limit or terminate our product development programs or any future commercialization efforts or grant rights to develop and commercialize product candidates to third parties that we would otherwise prefer to develop and commercialize ourselves.
Critical Accounting Policies and Significant Judgments and Estimates
Our management's discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles inthe United States . The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. There have been no changes to our critical accounting policies from those described under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Significant Judgments and Estimates" included in our Annual Report on Form 10-K filed with theSEC onFebruary 28, 2022 .
Recently issued accounting pronouncements
We have reviewed all recently issued standards and have determined that, other than as disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q, such standards will not have a material impact on our condensed consolidated financial statements or do not otherwise apply to our current operations.
