Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization | 1. Organization Description of business Aligos Therapeutics, Inc. (Aligos-US) was incorporated in the state of Delaware on February 5, 2018 (inception). On September 10, 2018, the Company formed Aligos Belgium BVBA (Aligos-Belgium), a limited liability company organized under the laws of Belgium. On March 30, 2020, the Company formed as a wholly owned subsidiary, Aligos Australia Pty LTD (Aligos-Australia), a proprietary limited company. On May 18, 2021, the Company formed as a wholly owned subsidiary, Aligos Therapeutics (Shanghai) Co. Ltd. (Aligos-Shanghai) and together with Aligos-US, Aligos-Belgium, and Aligos-Australia being the “Company” or “Aligos”. Aligos is a clinical-stage biopharmaceutical company developing novel therapeutics to address unmet medical needs in viral and liver diseases, including for chronic hepatitis B, coronaviruses and non-alcoholic steatohepatitis (NASH). The Company is devoting substantially all of its efforts to the research and development of its drug candidates. The Company has not generated any product revenue to date. The Company is also subject to a number of risks similar to other companies in the biotechnology industry, including the uncertainty of success of its nonclinical studies and clinical trials, regulatory approval of drug candidates, uncertainty of market acceptance of products, competition from substitute products and larger companies, the need to obtain additional financing, compliance with government regulations, protection of proprietary technology, dependence on third-parties, product liability, and dependence on key individuals. Initial public offering On October 20, 2020, the Company closed its initial public offering (IPO) at a public offering price of $ 15.00 per share for net proceeds of $ 135.4 million, after deducting underwriting discounts and commissions. On November 5, 2020, the underwriters of the IPO partially exercised their overallotment, resulting in an additional $ 16.0 million in net proceeds, after deducting underwriting discounts and commissions. Liquidity The Company has incurred losses and negative cash flows from operations since its inception. As of June 30, 2022 and December 31, 2021, the Company had an accumulated deficit of $ 358.6 million and $ 303.1 million , respectively. Management expects to continue to incur additional substantial losses in the foreseeable future as a result of expanded research and development activities. As of June 30, 2022, the Company has unrestricted cash, cash equivalents and investments of approximately $ 159.3 million which is available to fund future operations. The Company expects to continue to spend substantial amounts to continue the nonclinical and clinical development of its current and future programs. If the Company is able to gain marketing approval for drug candidates that are being developed, it will require significant additional amounts of cash in order to launch and commercialize such drug candidates. In addition, other unanticipated costs may arise. Because the design and outcome of the Company’s planned and anticipated clinical trials is highly uncertain, the Company cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of any drug candidate the Company may develop. The Company expects to finance its cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. In addition, the Company may seek additional capital to take advantage of favorable market conditions or strategic opportunities even if the Company believes it has sufficient funds for its current or future operating plans. Based on the Company’s research and development plans, the Company expects its existing unrestricted cash, cash equivalents and investments, will enable it to fund its operations for at least 12 months following the date the condensed consolidated financial statements are issued. However, the Company’s operating plan may change as a result of many factors currently unknown, and the Company may need to seek additional funds sooner than planned. Moreover, it is particularly difficult to estimate with certainty the Company’s future expenses given the dynamic nature of its business, the COVID-19 pandemic and the macro-economic environment generally. The Company’s ability to raise additional funds will depend on financial, economic and other factors, many of which are beyond its control. For example, the COVID-19 pandemic, the current inflationary economic environment and rising interest rates have resulted in a disruption of global financial markets. If the disruption persists or deepens, the Company could be unable to access additional capital, which could negatively affect its ability to consummate certain corporate development transactions or other important, beneficial or opportunistic investments. If additional funds are not available to the Company when needed, on terms that are acceptable to the Company, or at all, the Company may be required to: delay, limit, reduce or terminate nonclinical studies, clinical trials or other research and development activities or eliminate one or more of its development programs altogether; or delay, limit, reduce or terminate its efforts to establish manufacturing and sales and marketing capabilities or other activities that may be necessary to commercialize any future approved products, or reduce the Company’s flexibility in developing or maintaining its sales and marketing strategy. |

Accounting Policies [Abstract] | |
Summary of significant accounting policies | 2. Summary of significant accounting policies Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (ASC), and Accounting Standards Update (ASU) issued by the Financial Accounting Standards Board (FASB). The condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by U.S. GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to requirements for interim financial statements. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2022. Unaudited interim financial information The accompanying consolidated balance sheet as of June 30, 2022, the consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2022 and 2021, the consolidated statements of stockholders’ equity for the three and six months ended June 30, 2022 and 2021, and the consolidated statements of cash flows for the six months ended June 30, 2022 and 2021 are unaudited. The unaudited consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s consolidated financial position as of June 30, 2022 and the consolidated results of its operations and cash flows for the three and six months ended June 30, 2022 and 2021. The consolidated financial data and other information disclosed in these notes related to the three and six months ended June 30, 2022 and 2021 are unaudited. The consolidated results for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year or period. Significant Accounting Policies and Estimates No material changes have been made to the Company’s significant accounting policies disclosed in Note 2, Summary of Significant Accounting Policies , in its Annual Report on Form 10-K, filed on March 10, 2022, for the year ended December 31, 2021. Recently issued accounting standards From time to time, new accounting pronouncements are issued by FASB that the Company adopts as of the specified effective date. The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has the option to not “opt out” of the extended transition related to complying with new or revised accounting standards. This means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company has the option to adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and can do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company has considered all recent accounting pronouncements issued, but not yet effective, and does not expect any to have a material effect on the Company’s condensed consolidated financial statements other than those discussed in its Annual Report on Form 10-K, filed on March 10, 2022, for the year ended December 31, 2021. |

Fair Value Disclosures [Abstract] | |
Fair value | 7. Fair value Certain assets and liabilities of the Company are carried at fair value under U.S. GAAP. Fair value is defined as 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: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs (other than Level 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. 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. The following tables present the fair value of the Company’s financial instruments that are measured or disclosed at fair value on a recurring basis (in thousands): Fair Value Measurements Level 1 Level 2 Level 3 Assets: Cash equivalents $ 71,172 $ - $ - Certificates of deposit 88,172 - - $ 159,344 $ - $ - Fair Value Measurements Level 1 Level 2 Level 3 Assets: Cash equivalents $ 186,816 $ - $ - Certificates of deposit 3,918 - - U.S. Treasury bonds 15,110 - - $ 205,844 $ - $ - |

License And Collaboration Agreements [Abstract] | |
License and collaboration agreements | 8. License and collaboration agreements Agreement with Emory University (Emory) In June 2018, the Company entered into a license agreement with Emory (the Emory License Agreement), pursuant to which Emory granted the Company a worldwide, sublicensable license under certain of its intellectual property rights to make, have made, develop, use, offer to sell, sell, import and export products containing certain compounds relating to Emory’s hepatitis B virus capsid assembly modulator technology, for all therapeutic and prophylactic uses. Such license is initially exclusive with respect to specified licensed patents owned by Emory and non-exclusive with respect to certain of Emory’s specified know-how. Beginning in June 2022, the license to such patents will become non-exclusive with respect to all fields except for the treatment and prevention of HBV; however, the Company may select up to six compounds which will maintain exclusivity with respect to all therapeutic and prophylactic uses. With respect to all other compounds that are enabled by the licensed patents, those which are jointly invented by the Company and Emory or inventors in the Schinazi laboratory, or which are disclosed in a specified licensed patent, are licensed to the Company exclusively including as to Emory; whereas all other such compounds are licensed to the Company non-exclusively. Under the terms of the Emory License Agreement, the Company is obligated to use commercially reasonable efforts to bring licensed products to market in accordance with a mutually agreed upon development plan. Unless terminated earlier by either party in accordance with the provisions thereof, the Emory License Agreement shall continue until the expiration of the last–to-expire of the patents licensed to the Company thereunder. As consideration for the Emory License Agreement, the Company paid an upfront license fee of $ 0.3 million and issued a convertible note with a principal amount of $ 0.6 million. Upon issuance of the Series A in August 2018, the principal and unpaid accrued interest under this convertible note was cancelled and converted into shares of Series A at a conversion price of $ 9.32 per share. In June 2020, the Company amended the license agreement with Emory. Pursuant to the amended license agreement, Emory granted the Company additional patent rights to certain compounds targeting the treatment or prevention of HBV. As consideration for the additional rights, the Company made a one-time, non-refundable payment to Emory in the amount of $ 0.2 million, with an additional obligation to pay up to a maximum of $ 35,000 . On the same date, the Company entered into a collaboration agreement with Emory, with the initial research plan pertaining to the synthesis and evaluation of the compounds licensed through the additional patent rights granted in the amended license agreement. The research plan terminates one year from the effective date, with the Company having an option to extend for a second year. In connection with the research plan, the Company will provide Emory funding up to $ 0.3 million per year. The Company has agreed to pay Emory up to an aggregate of $ 125.0 million upon the achievement of specified development, regulatory, and commercial milestones, and all ongoing patent costs. During the three and six months ended June 30, 2022 and 2021 , the Company had no expenses related to milestone payments. The Company also agreed to pay Emory tiered single-digit royalties on worldwide annual net sales of licensed products, on a quarterly basis and calculated on a product-by-product basis. With respect to licensed products containing any of a specified subset of the licensed compounds, such royalties range from a mid-single digit to a high-single digit percentage rate. With respect to licensed products which do not contain such compounds, the royalties span a range of percentage rates within the mid-single digits if a Phase 1 clinical trial is initiated for the product within three years of the effective date of the Emory License Agreement, and range from a low-single digit to a mid-single digit rate if a Phase 1 clinical trial is initiated more than three years after the effective date. During the three and six months ended June 30, 2022 and 2021 , the Company made no payments associated with royalties and recognized no expense or accruals. Agreement with Luxna Biotech Co., Ltd. (Luxna) On December 19, 2018, the Company entered into a license agreement with Luxna, pursuant to which Luxna granted the Company an exclusive, worldwide, sublicensable license under certain of Luxna’s intellectual property rights to research, develop make, have made and commercialize for all therapeutic and prophylactic uses, (i) products containing oligonucleotides targeting the hepatitis B virus genome, (ii) products containing certain oligonucleotides targeting up to three genes which contribute to NASH, which the Company may select at any time during the first eight years of the term, to the extent not licensed to a third party, and (iii) products containing oligonucleotides targeting up to three genes which contribute to hepatocellular carcinoma, which the Company may select at any time during the first three years of the term. As consideration for this agreement, the Company paid an upfront license fee of $ 0.6 million, which was recorded as research and development expense during the period from inception through December 31, 2018 and the year ended December 31, 2019. In April 2020, the Company amended the license agreement with Luxna. Pursuant to the amended license agreement, Luxna granted the Company an exclusive, worldwide license under the licensed patents to research, develop, make, have made and commercialize products containing oligonucleotides targeting three families of viruses: orthomyxoviridae, paramyxoviridae, and coronaviridae (a family which includes SARS-CoV-2). As consideration for the amended license agreement, the Company paid Luxna a one-time non-refundable fee of $ 0.2 million in April 2020. The Company is obligated to make payments to Luxna, in aggregate, totaling up to but no more than $ 55.5 million upon the achievement of specified development, regulatory, and commercial milestones. During the three and six months ended June 30, 2022 and 2021 , the Company recognized no expenses related to milestone payments. The Company is also required to pay Luxna a low-single digit royalty percentage on net sale of applicable products, if any. During the three and six months ended June 30, 2022 and 2021 , the Company made no payments associated with royalties. Agreement with Katholieke Universiteit Leuven (KU Leuven) On June 25, 2020, the Company entered into a Research, Licensing and Commercialization Agreement (KU Leuven Agreement) with KU Leuven, under which the Company is collaborating with KU Leuven’s Rega Institute for Medical Research, as well as its Centre for Drug Design and Discovery, to research and develop potential protease inhibitors for the treatment, diagnosis or prevention of coronaviruses, including of SARS-CoV-2. Unless terminated earlier by either party in accordance with provisions in the agreement, the collaboration period will terminate at the earlier of completion of all collaboration activities or 2.5 years. In connection with the KU Leuven Agreement, KU Leuven and the Company granted each other exclusive cross-licenses to use certain know-how and existing patents of the other party as well as certain joint know-how and joint patents to carry out research and development collaboration activities during the collaboration period. KU Leuven granted to the Company an exclusive (including as to KU Leuven), worldwide license under certain of KU Leuven’s know-how and existing patents, and certain joint patents and joint know-how, to manufacture and commercialize the licensed products for the treatment, diagnosis or detection of viral infections in humans. KU Leuven reserved the right to use all KU Leuven knowhow, existing KU Leuven patents, joint patents and joint know-how for academic and non-commercial research and teaching purposes. As consideration for this license, the Company is obligated to make payments to KU Leuven, in aggregate, totaling up to but no more than $ 30.0 million upon the achievement of certain commercial sales milestones. For each licensed product developed through KU Leuven and the Company’s collaborative effort, the Company is obligated to make payments to KU Leuven, in aggregate, totaling up to $ 32.0 million upon the achievement of certain development and regulatory milestones. The Company is also required to pay KU Leuven a low-to-mid-single digit royalty percentage, subject to certain adjustments, on net sales of applicable products, if any. Unless terminated earlier by either party, the agreement shall continue until the expiration of the last to expire royalty term, which is the later of the expiration or termination of the last valid patent claim covering the manufacture, use, sale or importation of the licensed product in a particular country or 10 years after the first commercial sale of a licensed product. During the three and six months ended June 30, 2022 and 2021 , the Company recognized no expenses related to milestone payments. Agreements with Merck In December 2020, the Company and Merck & Co. entered into an exclusive License and Research Collaboration Agreement under which Merck and the Company agreed to apply the Company’s oligonucleotide platform technology to discover, research, optimize and develop oligonucleotides directed against a NASH target and up to one additional liver-targeted cardiometabolic and/or fibrosis target. Under the terms of the agreement, the Company received an upfront payment from Merck and may receive an additional upfront payment after finalization of a research plan for such additional target. With respect to each collaboration target, the Company will be eligible for up to $ 458.0 million in development and commercialization milestones as well as tiered royalties on net sales. The Company will be primarily responsible for designing, preparing and evaluating the oligonucleotide molecules and delivering optimized lead molecules, and Merck will be responsible for subsequent research, clinical development and commercialization efforts. The Company determined that the Merck agreement falls within the scope of ASC 808 and the Company analogized to ASC 606 for the accounting of payments such as upfront payments and other milestones. Revenue is recognized based on percentage of completion of the overall project. During the three and six months ended June 30, 2022 the Company recognized $ 2.0 million and $ 3.6 million , respectively, and in the three and six months ended June 30, 2021 the Company recognized $ 1.5 million and $ 2.5 million , respectively, of revenue from collaborative arrangements related to milestone payments. In January 2022, the Company and Merck & Co. entered into a First Amendment to the License and Research Collaboration Agreement. The agreement was expanded to include the in-license by Merck of an early-stage program with respect to a second undisclosed NASH target, on which the Company had previously been working independently on. In addition, under this expanded arrangement, Merck has the ability to add an additional third target of interest in the cardiometabolic/fibrosis space to the collaboration. Under the expanded agreement, the Company will receive a payment from Merck for the in-license of the program directed at a second undisclosed NASH target. Moreover, the Company will receive an additional payment if a third target is designated for the collaboration. With respect to each target in the collaboration, the Company will be eligible to receive up to approximately $ 460.0 million in development and commercialization milestones as well as tiered royalties on net sales. The Company determined that the First Amendment to the Merck agreement also falls within the scope of ASC 808 and the Company analogized to ASC 606 for the accounting of payments such as upfront payments and other milestones. Revenue is recognized based on the percentage of completion of the amended agreement. During the three and six months ended June 30, 2022 the Company recognized $ 1.7 million and $ 2.7 million , respectively, of revenue from the amended collaborative arrangement related to milestone payments. |

Therefore, the weighted-average number of shares of Common Stock outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential shares of Common Stock, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect: Three Months Ended Six Months Ended June 30, June 30, 2022 2021 2022 2021 Options to purchase common stock 9,012,369 5,550,324 9,012,369 5,550,324 Unvested restricted stock 3,717 224,688 3,717 224,688 9,016,086 5,775,012 9,016,086 5,775,012 |

Discontinued Development of Drug Candidates [Abstract] | |
Discontinued development of drug candidates | 12. Discontinued Development of Drug Candidates STOPS TM drug candidate, ALG-010133 On January 6, 2022, the Company announced that it had halted further development of its STOPS TM drug candidate, ALG‑010133, which was being developed as a potential therapy for chronic hepatitis B (CHB). This decision was based on emerging data from the Phase 1 Study ALG‑010133-101 indicating that at the projected efficacious dose (400 mg, estimated to achieve liver exposures >3 x EC 90 for HBsAg inhibition) there was no meaningful HBsAg reduction. Furthermore, a higher dosage level (maximum feasible dose of 600 mg) that was planned to be evaluated in a subsequent cohort was assessed to be very unlikely to reach the 1 log 10 IU/mL HBsAg reduction level that the Company had previously defined as necessary to advance the program. No dose limiting safety findings have been identified in CHB subjects dosed at any dose level. In early January, based on this information, the Company's management reviewed the data with members of the study’s Study Review Committee, and jointly concluded that the data were not sufficient to support further development of ALG‑010133. The halt of ALG‑010133 resulted in a charge of approximately $ 3.8 million related to non-cancelable purchase obligations that was recognized during the six months ended June 30, 2022. Antisense Oligonucleotide (ASO) drug candidate, ALG-020572 On March 22, 2022, the Company announced that it had discontinued development of its ASO drug candidate, ALG‑020572, which was being studied in subjects with CHB. Dosing in the first CHB cohort of Study ALG‑020572-401 was stopped after one subject experienced a serious adverse event (SAE) with significant increase in alanine aminotransferase (ALT) following the administration of multiple doses of 210 mg ALG‑020572 that resulted in a brief hospitalization. Four subjects in CHB Cohort 1, including the hospitalized subject, experienced significant ALT flares following multiple dosing; these were unexpected based on prior experience in nonclinical studies and single dose administration in healthy volunteers. Based on this information, the Company concluded that the program should be discontinued. In all four subjects, laboratory parameters and symptoms are improving, and the hospitalized subject has been discharged. The Company plans to use any cost savings from the discontinuation of the ALG‑020572 program to further support clinical and small molecule preclinical development programs, all of which target novel mechanisms that have the potential to enhance the care of patients with CHB, nonalcoholic steatohepatitis and COVID-19. The halt of ALG‑020572 resulted in a charge of approximately $ 3.4 million related to non-cancelable purchase obligations that was recognized during the six months ended June 30, 2022 . |

Recently issued accounting standards | Recently issued accounting standards From time to time, new accounting pronouncements are issued by FASB that the Company adopts as of the specified effective date. The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has the option to not “opt out” of the extended transition related to complying with new or revised accounting standards. This means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company has the option to adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and can do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company has considered all recent accounting pronouncements issued, but not yet effective, and does not expect any to have a material effect on the Company’s condensed consolidated financial statements other than those discussed in its Annual Report on Form 10-K, filed on March 10, 2022, for the year ended December 31, 2021. |
