Accounting Policies [Abstract]
Basis of Presentation	The accompanying interim condensed financial statements were prepared in conformity with U.S. GAAP and with Article 10 of Regulation S-X for interim financial reporting. In compliance with those rules, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed financial statements should be read in conjunction with the Company’s audited financial statements and related notes for the fiscal year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 5, 2025 (the “2024 Annual Report on Form 10-K”). As included herein, the Condensed Balance Sheet as of December 31, 2024 is derived from the audited financial statements as of that date. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the results of interim periods have been included. The accompanying condensed financial statements reflect certain reclassifications from previously issued financial statements to conform to the current presentation. The Company has evaluated subsequent events for disclosure through the date of issuance of the accompanying condensed financial statements. Any reference in the Notes to applicable guidance refers to the authoritative U.S. GAAP as found in the ASC and ASU of FASB.
Recent Accounting Pronouncements	From time to time, new accounting pronouncements are issued by the FASB and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. Recent Accounting Pronouncements Adopted as of June 30, 2025: In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ASU 2023-07, which requires all public entities, including public entities with a single reportable segment, to provide in interim and annual periods one or more measures of segment profit or loss used by the CODM to allocate resources and assess performance. Additionally, the standard requires disclosures of significant segment expenses and other segment items as well as incremental qualitative disclosures. The guidance in this update is effective for fiscal years beginning after December 15, 2023, and interim periods after December 15, 2024. The Company adopted the new disclosure requirements as of December 31, 2024. Refer to Note 4, Segment Reporting for the required disclosure. In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This ASU was issued to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Among other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. More specifically, the ASU reduces the number of models that may be used to account for convertible instruments from five to three, amends diluted EPS calculations for convertible instruments, modifies the requirements for a contract that may be settled in an entity’s own shares to be classified in equity and requires expanded disclosures intended to increase transparency. The Company adopted the new guidance on January 1, 2024. The adoption of this guidance did not have a material impact on the Company’s financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. This ASU was issued to clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, and to introduce new disclosure requirements for such equity securities. The Company adopted the new guidance on January 1, 2024. The adoption of this guidance did not have a material impact on the Company’s financial statements. Recent Accounting Pronouncements Not Adopted as of June 30, 2025: In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 will require the Company to disclose the amounts of purchases of inventory, employee compensation, depreciation and intangible asset amortization, as applicable, included in certain expense captions in the Statements of Operations, and Comprehensive Loss as well as qualitatively describe the remaining amounts included in those captions. ASU 2024-03 will also require the Company to disclose both the amount and the Company’s definition of selling expenses. These disclosure requirements will be effective for the Company for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact from the adoption of ASU 2024-03 on disclosures to its financial statements. In December 2023, the FASB issued ASU 2023-09—Income Taxes (Topic 740)—Improvements to Income Tax Disclosures. This ASU was issued to enhance the transparency and decision usefulness of income tax disclosures. The ASU requires that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). It further requires disclosure on an annual basis of the following information about income taxes paid: 1. The amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes 2. The amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). Additionally, it requires the following information disclosure: 1. Income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign 2. Income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The ASU eliminates certain current disclosure requirements. These disclosure requirements will be effective for the Company for fiscal years beginning after December 15, 2025, with early adoption of the amendments permitted. The Company is currently evaluating the impact from the adoption of ASU 2023-09 on disclosures to its financial statements.
Revenue Recognition and Performance Obligations	The Company’s revenues include (i) sales of manufactured products pursuant to contracts with commercialization licensees, (ii) license and royalty revenues, (iii) co-development and research fees generally in the form of milestone payments, and (iv) sales of its proprietary CNS product, Libervant, for patients between two to five years of age while Libervant had U.S. market access through April 2025. The Company recognizes revenue to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, a five-step model is applied that includes (1) identifying the contract with a customer, (2) identifying the performance obligation in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing when, or as, an entity satisfies a performance obligation. Performance Obligations - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in the current revenue recognition standard. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. At contract inception, the Company assesses the goods promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a distinct good. When identifying performance obligations, the Company considers all goods or services promised in a contract regardless of whether explicitly stated in the contract or implied by customary business practice. The Company’s performance obligations consist mainly of transferring goods and services identified in the contracts, purchase orders, invoices or statements of work. Manufacture and supply revenue – this revenue is derived from products manufactured exclusively for specific customers according to their strictly-defined specifications, subject only to specified quality control inspections. Accordingly, at the point in time when quality control requirements are satisfied, revenue net of related discounts is recorded. License and Royalty Revenue – license revenues are determined based on an assessment of whether the license is distinct from any other performance obligations that may be included in the underlying licensing arrangement. If the customer is able to benefit from the license without provision of any other performance obligations by the Company and the license is thereby viewed as a distinct or functional license, the Company then determines whether the customer has acquired a right to use the license or a right to access the license. For functional licenses that do not require further development or other ongoing activities by the Company, the customer is viewed as acquiring the right to use the license as, and when, transferred and revenues are generally recorded at a point in time, subject to contingencies or constraints. For symbolic licenses providing substantial value only in conjunction with other performance obligations to be provided by the Company, revenues are generally recorded over the term of the license agreement. Such other obligations provided by the Company generally include manufactured products, additional development services or other deliverables that are contracted to be provided during the license term. Payments received in excess of amounts ratably or otherwise earned are deferred and recognized over the term of the license or as contingencies or other performance obligations are met. Royalty revenue is estimated and recognized when sales under supply agreements with commercial licensees are recorded, absent any contractual constraints or collectability uncertainties. Royalties based on sales of licensed products have been recorded in this manner. Revenue recognition arising from milestone payments is dependent upon the facts and circumstances surrounding the milestone payments. Milestone payments based on a non-sales metric such as a development-based milestone (i.e., an NDA filing or obtaining regulatory approval) represent variable consideration and are included in the transaction price subject to any constraints. If the milestone payments relate to future development, the timing of recognition depends upon historical experience and the significance a third party has on the outcome. For milestone payments to be received upon the achievement of a sales threshold, the revenue from the milestone payments is recognized at the later of when the actual sales occur or the performance obligation to which the sales relate to has been satisfied. Co-development and Research Fees – co-development and research fees are earned through performance of specific tasks, activities or completion of stages of development defined within a contractual development or feasibility study agreement with a customer. The nature of these performance obligations, broadly referred to as milestones or deliverables, are usually dependent on the scope and structure of the project as contracted, as well as the complexity of the product and the specific regulatory approval path necessary for that product. Accordingly, the duration of the Company’s R&D projects may range from several months to approximately three years. Although each contractual arrangement is unique, common milestones included in these arrangements include those for the performance of efficacy and other tests, reports of findings, formulation of initial prototypes, production of stability clinical and/or scale-up batches, and stability testing of those batches. Additional milestones may be established and linked to clinical results of the product submission and/or approval of the product by the FDA and the commercial launch of the product. Proprietary product revenue, net - this net revenue is recognized when product is shipped and title passes to the customer, typically at time of delivery. At the time of sale, estimates for various revenue allowances are recorded based on historical trends and judgmental estimates. For sales of Libervant for patients between two to five years of age while Libervant had U.S. market access through April 2025, returns allowances and prompt pay discounts are estimated based on contract terms and historical return rates, if available, and these estimates are recorded as a reduction of receivables. Once receivables are collected, allowances are reclassified and treated as accrued liabilities. Similarly determined estimates are recorded relating to wholesaler service fees, co-pay support redemptions, and other rebates, and these estimates are reflected as a component of accrued liabilities. Once related variable considerations are resolved and uncertainties as to incurred amounts are eliminated, estimates are adjusted to actual allowance amounts. Provisions for these estimated amounts are reviewed and adjusted on no less than a quarterly basis. Contract Assets - in certain situations, customer contractual payment terms provide for invoicing in arrears. Accordingly, some, or all performance obligations may be completely satisfied before the customer may be invoiced under such agreements. In these situations, billing occurs after revenue recognition, which results in a contract asset supported by the estimated value of the completed portion of the performance obligation. These contract assets are reflected as a component of other receivables within Trade and other receivables within the Condensed Balance Sheets. As of June 30, 2025, and December 31, 2024, such contract assets were $645 and $578, respectively, consisting primarily of products and services provided under specific contracts to customers for which earnings processes have been met prior to shipment of goods or full delivery of completed services, as well as estimated receivables from contracts with third parties. Contract Liabilities - in certain situations, customer contractual payment terms are structured to permit invoicing in advance of delivery of a good or service. In such instances, the customer’s cash payment may be received before satisfaction of some, or any, performance obligations that are specified. In these situations, billing occurs in advance of revenue recognition, which results in contract liabilities. These contract liabilities are reflected as deferred revenue within the Condensed Balance Sheets. As remaining performance obligations are satisfied, an appropriate portion of the deferred revenue balance is credited to earnings. As of June 30, 2025 and December 31, 2024, such contract liabilities were $21,027 and $21,053, respectively. Costs to Obtain Contracts - in certain situations, the Company may incur incremental costs of obtaining a contract with a customer. These costs, if expected to be recovered, are recognized as an asset and reflected as other assets within the Condensed Balance Sheets. The asset is amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. As of June 30, 2025 and December 31, 2024, such costs to obtain contracts were $465 and $480, respectively.
