Accounting Policies [Abstract] |
Organization | Organization Eliem Therapeutics, Inc. (the Company) is a biotechnology company focused on developing novel therapies for neuronal excitability disorders to address unmet needs in psychiatry, epilepsy, chronic pain, and other disorders of the peripheral and central nervous systems. The Company was incorporated on October 18, 2018 as a Delaware corporation and is headquartered in Delaware. On February 7, 2023, the Company’s board of directors approved a restructuring plan (the Restructuring Plan) to conserve financial resources and better align the Company’s workforce with current business needs, as a result of the decision to pause development of ETX-155 and focus on the Company’s preclinical Kv7 program. As part of the Restructuring Plan, the Company's workforce was reduced by approximately 55%, with substantially all of the reduction in personnel completed in the first half of 2023. On July 20, 2023, the Company announced that it made the determination to conduct a comprehensive exploration of strategic alternatives focused on maximizing stockholder value. As part of that effort, the Company has paused further development of its Kv7 program, while continuing ongoing preclinical studies and exploring options for both Kv7 and ETX-155.
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying interim condensed consolidated financial statements of the Company and its wholly owned subsidiary have been prepared in conformity with accounting principles generally accepted in the United States (U.S. GAAP). All intercompany transactions and balances have been eliminated in consolidation. The accompanying condensed consolidated balance sheet as of September 30, 2023, and condensed consolidated statements of operations and comprehensive loss, condensed consolidated statements of cash flows, and condensed consolidated statements of stockholders’ equity for the three and nine months ended September 30, 2023 and 2022, are unaudited. The consolidated balance sheet as of December 31, 2022 was derived from the audited financial statements as of and for the year ended December 31, 2022, but does not include all disclosures required by U.S. GAAP. The unaudited interim condensed financial statements have been prepared on a basis consistent with the audited annual financial statements as of and for the year ended December 31, 2022, and, in the opinion of management, reflect all adjustments, consisting solely of normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2023, the condensed results of its operations as of the three and nine months ended September 30, 2023 and 2022, and its cash flows for the nine months ended September 30, 2023 and 2022. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2023 and 2022 are also unaudited. The condensed results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023 or any other period. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 6, 2023.
Liquidity | Liquidity Since inception, the Company has experienced recurring losses from operations and generated negative cash flows from operations. The Company has an accumulated deficit of $152.3 million as of September 30, 2023 and expects to incur additional losses from operations in the future. The Company estimates the available cash, cash equivalents, and marketable securities of $107.4 million as of September 30, 2023 will be sufficient to meet its projected operating requirements for at least the next twelve months from the filing date of these unaudited condensed consolidated financial statements and the Company anticipates that it will need to raise substantial financing in the future to fund its operations. The Company may finance future cash needs through equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements. In addition, the Company may continue to rely on capital markets, and to a lesser extent, United Kingdom (U.K.) research and development tax credits and incentives for funding. There are no assurances that the Company will be able to raise sufficient amounts of funding in the future on acceptable terms, or at all.
Use of Estimates | Use of Estimates The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Key management estimates include those related to the accrual of research and development expenses, recoverable research and development tax credits, and the valuation of stock-based awards. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities. The Company’s cash is held by two financial institutions in the United States (U.S.) and two financial institutions in the U.K. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company’s deposits held in the U.S. and U.K. may exceed the Federal Depository Insurance Corporation and Financial Services Compensation Scheme, respectively, insured limits. The Company has diversified investments in money market funds, U.S. Treasury and government agency debt securities, commercial paper, and corporate bonds with high-quality accredited financial institutions, which are held in a segregated account at a third-party custodian. The Company has established guidelines relative to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. Through September 30, 2023, and the date of this filing, the Company has not experienced any losses on such deposits.
Risks and Uncertainties | Risks and Uncertainties The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, reliance on single-source vendors and collaborators, availability of raw materials, patentability of the Company’s products and processes and clinical efficacy and safety of the Company’s products under development, compliance with government regulations and the need to obtain additional financing to fund operations. Any product candidates the Company may develop in the future will require significant additional research and development efforts, including extensive preclinical studies, clinical trials, and regulatory approval, prior to commercialization. These efforts will require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance and reporting. There can be no assurance that any future research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained or maintained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if any future product development efforts are successful, it is uncertain when, if ever, the Company will generate revenue from product sales. The Company operates in an environment of rapid technological change and substantial competition from other pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its employees, consultants and other third parties
Segments | Segments Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker (the CODM). The Company’s CODM is its executive chairman who reviews financial information together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. Management has determined that the Company operates as a single operating and reportable segment. The Company’s CODM evaluates financial information on a consolidated basis. As the Company operates as one operating segment, all required segment financial information is found in the interim condensed consolidated financial statements.
Fair Value Measurement | Fair Value Measurement Assets and liabilities recorded at fair value on a recurring basis in the balance sheet are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability 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. The Company measures fair value based on a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liabilities. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. In determining fair value, the Company utilizes quoted market prices, or valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. There were no transfers into or out of Level 3 for any of the periods presented. The Company’s fair value measurements as of September 30, 2023 and December 31, 2022 was as follows (in thousands):

Summary of Significant Accounting Policies | Summary of Significant Accounting Policies There have been no material revisions in the Company's significant accounting policies described in Note 2 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard changes how entities will measure credit losses for most financial assets, including accounts and notes receivables. The standard will replace today’s “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Based on the Company's status as an emerging growth company (EGC), the Company follows the adoption calendar for non-public companies and as such, the effective date of this update is for fiscal years beginning after December 15, 2022 and interim periods therein. The Company adopted ASU 2016-13 on January 1, 2023, which did not have a material impact on its condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted 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. The standard simplifies accounting for convertible instruments by removing major separation models required under current GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. The standard also simplifies the diluted net income per share calculation in certain areas. Based on the Company's status as an EGC, the Company follows the adoption calendar for non-public companies and as such, the effective date of this update is for fiscal years beginning after December 15, 2023, including interim periods therein. Early adoption is permitted for fiscal years beginning after December 15, 2020 and interim periods therein. The Company estimates that adoption will not have a material impact on its consolidated financial statements. There were no other significant updates to the recently issued accounting standards other than as disclosed herewith for the nine months ended September 30, 2023. Although there are several other new accounting pronouncements issued or proposed by the FASB, the Company does not believe any of those accounting pronouncements have had or will have a material impact on its financial position or operating results.
