Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting [Text Block]	1. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of CASI Pharmaceuticals, Inc. and its subsidiaries (“CASI” or “the Company”), Miikana Therapeutics, Inc. (“Miikana”) and CASI Pharmaceuticals (Beijing) Co., Ltd. (“CASI China”). The Company previously operated under a different name prior to restructuring its business in 2012 in connection with an investment led by one of the Company’s largest stockholders. CASI China is a non-stock Chinese entity with 100% of its interest owned by CASI. CASI China received approval for a business license from the Beijing Industry and Commercial Administration in August 2012 and has operating facilities in Beijing. All inter-company balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, such condensed consolidated financial statements do not include all of the information and disclosures required by U.S. generally accepted accounting principles for complete consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The accompanying December 31, 2017 financial information was derived from the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Operating results for the three and nine month periods ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 or any other future period. For further information, refer to the Company’s audited consolidated financial statements and footnotes thereto included in its Form 10-K for the year ended December 31, 2017. Liquidity Risks and Management’s Plans Since inception, the Company has incurred significant losses from operations and has incurred an accumulated deficit of $469.7 million. The Company restructured its business in 2012 in connection with an investment led by one of the Company’s largest stockholders, followed by implementation of a name change to reflect its core mission and business strategy. The Company expects to continue to incur operating losses for the foreseeable future due to, among other factors, its continuing clinical and development activities. In September 2018, the Company entered into securities purchase agreements with certain institutional investors, accredited investors and current stockholders, pursuant to which the Company agreed to sell 9,048,504 shares of its common stock with accompanying warrants to purchase 2,714,548 shares of its common stock in a $48.5 million private placement (the “September 2018 Financing”). The Company held its initial closing on September 24, 2018 (the “September 2018 Closing”) and second closing on October 10, 2018 (the “October 2018 Closing”). The Company has received gross proceeds of $37.5 million and expects to receive additional gross proceeds of $11 million. Additionally, in March 2018, the Company entered into securities purchase agreements pursuant to which the Company issued 15,432,091 shares of its common stock with accompanying warrants to purchase 6,172,832 shares of its common stock and received $50 million in gross proceeds in a private placement (the “March 2018 Financing”). The March 2018 Financing closing included an investment from ETP Global Fund, L.P., a healthcare investment fund. The managing member of Emerging Technology Partners, LLC, which is the general partner of ETP Global Fund, L.P., is also the Executive Chairman of the Company. The March 2018 Financing also included an investment from IDG-Accel China Growth Fund III L.P. (“IDG-Accel Growth”) and IDG-Accel China III Investors L.P. (“IDG-Accel Investors”). A director and shareholder of IDG-Accel China Growth Fund GP III Associates Ltd., which is the ultimate general partner of IDG-Accel Growth and IDG-Accel Investors, is also a member of the Company’s Board of Directors. Net proceeds from the September 2018 Closing, the October 2018 Closing, and the March 2018 Financing are being used to prepare for the anticipated launch of the Company’s first commercial product in China, to support the Company’s business development activities, to advance the development of the Company’s pipeline, to support its marketing and commercial planning activities, and for other general corporate purposes. As a result of the September 2018 Closing, October 2018 Closing, and the March 2018 Financing, the Company believes that it has sufficient resources to fund its operations at least through November 14, 2019. As of September 30, 2018, approximately $15.2 million of the Company’s cash balance was held by CASI China. The Company intends to continue to exercise tight controls over operating expenditures and will continue to pursue opportunities, as required, to raise additional capital and will also actively pursue non- or less-dilutive capital raising arrangements in China to support the Company’s dual-country approach to drug development.

Acquisition of Abbreviated New Drug Applications [Abstract]
Acquisition of Abbreviated New Drug Applications [Text Block]	2. Acquisition of Abbreviated New Drug Applications On January 26, 2018, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Sandoz, Inc. (“Sandoz”). Pursuant to the Asset Purchase Agreement, the Company acquired a portfolio of 29 abbreviated new drug applications (“ANDAs”), including 25 ANDAs approved by the U.S. Food and Drug Administration (“FDA”) and four pipeline ANDAs that are pending FDA approval, limited quantities of certain active pharmaceutical ingredient (“API”), and certain manufacturing and other information related to the products (collectively, the ANDAs, API and other information are referred to as the “Acquired Assets”). To facilitate the sale and transition, the parties also entered into several limited term ancillary arrangements. The Acquired Assets enhance the Company’s strategic focus to build a robust pipeline and commercialize quality drug candidates in China. The Company intends to select and commercialize certain products from the portfolio that have unique market and cost-effective manufacturing opportunities in China (and potentially in the U.S.). The total purchase price for the Acquired Assets was $18.0 million in cash. The Company accounted for the purchase of the Acquired Assets as an asset acquisition (consisting of a concentrated group of similar identifiable assets, including ANDAs and API) following the guidance contained in Accounting Standards Update (“ASU”) 2017-01. The total purchase price, along with approximately $1.2 million of transaction expenses, was allocated to the Acquired Assets based on their relative fair values, as follows: ANDAs $ 18,608,000 API 564,000 Total value $ 19,172,000 Of the total value allocated to the ANDAs, approximately $553,000 was immediately expensed as acquired in-process research and development since the underlying ANDAs have not been approved by the FDA, and of the total value allocated to the API, approximately $134,000 was immediately expensed as acquired in-process research and development since the Company does not intend to use all of the API. The allocated cost of the capitalized ANDAs will be amortized over their estimated useful lives of 13 years. The capitalized API will be expensed in the period it is used or if its value is otherwise impaired. The fair values of certain acquired ANDAs were estimated using the discounted cash flow method (an income approach), which involves the use of Level 3 inputs such as estimates for projected sales, expenses, and cash flows, estimates of total addressable markets and market penetration rates, future sales growth and inflation rates, expected income and value-added tax rates, and a required rate of return adjusted for both industry and Company-specific risks, among other inputs. The fair values of the remaining ANDAs were estimated using a multiple of values method (an income approach), which involved using Level 3 inputs such as estimated addressable markets and market penetration rates. The fair value of the API was estimated using Level 2 inputs, such as quoted market prices for similar API from various suppliers or other sources. The ANDAs will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable; no such triggering events were identified during the period from the date of acquisition to September 30, 2018.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets Disclosure [Text Block]	3. Intangible Assets Intangible assets were acquired as part of the 2018 asset acquisition from Sandoz and include ANDAs for a total of 25 previously marketed generic products. These intangible assets were originally recorded at relative fair values based on the purchase price for the asset acquisition and are stated net of accumulated amortization. The ANDAs are being amortized over their estimated useful lives of 13 years, using the straight-line method. Management reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, in a manner similar to that for property and equipment. No impairment losses related to intangible assets were recognized in the nine months ended September 30, 2018. As discussed in Note 2, in January 2018, the Company purchased the Acquired Assets from Sandoz for a total purchase price of $18.0 million. The total purchase price, along with transaction expenses of approximately $1.2 million, was allocated to the ANDAs and API acquired based on their relative fair values. Net finite-lived intangible assets at September 30, 2018 consists of the following: Asset Gross Value Accumulated Amortization Estimated useful lives ANDAs $ 18,054,985 $ (944,563 ) 13 years Expected future amortization expense is as follows for the years ending December 31: 2018 (remaining three months) $ 347,212 2019 1,388,845 2020 1,388,845 2021 1,388,845 2022 1,388,845 2023 and thereafter 11,207,830

Foreign Currency Translation

Foreign Currency [Abstract]
Foreign Currency Disclosure [Text Block]	4. Foreign Currency Translation The U.S. dollar is the reporting currency of the Company. Foreign currency denominated assets and liabilities of the Company and its foreign subsidiary are translated into U.S. dollars. Accordingly, assets and liabilities are translated using the exchange rates in effect at the consolidated balance sheet date and revenues and expenses at the rates of exchange prevailing when the transactions occurred, using an average periodic exchange rate. In 2017, remeasurement adjustments were included in income (loss). As discussed in Note 2, on January 26, 2018, the Company acquired a portfolio of ANDAs. Management believes that this transaction provides significant and permanent changes to its operations in China, and that it may allow its subsidiary in China to generate operating revenues from the China marketplace in the future and potentially sustain its own operations without the necessity of parent support. Accordingly, effective January 1, 2018, the functional currency of the Company’s subsidiary based in China has been changed to the local currency of the China Renminbi (“RMB”). The change in functional currency did not have a material impact on the consolidated financial statements. Beginning January 1, 2018, translation gains and losses relating to the financial statements of the Company’s China subsidiary are included as accumulated other comprehensive loss in the accompanying Condensed Consolidated Balance Sheets.

Schedule of Investments [Abstract]
Investment Holdings, Schedule of Investments [Text Block]	5. Investments The Company has an equity investment in the publicly traded common stock of a company. Beginning on January 1, 2018 with the adoption of ASU 2016-01, the Company’s investment in this equity security is considered a trading security and is carried at its estimated fair value, with changes in fair value reported in the statement of operations each reporting period. The fair value of this security was measured using its quoted market price, a Level 1 input, and was approximately $1.2 million as of September 30, 2018. In January 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-01, “Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” In February 2018, the FASB issued ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” The accounting standards primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, it includes a clarification related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017. The Company adopted ASU 2016-01 and ASU 2018-03 on January 1, 2018 and recorded a cumulative effect adjustment that decreased accumulated deficit by approximately $1.2 million. Effective January 1, 2018, the adoption date, changes in the fair value of the Company’s investments in equity securities are recognized in the statements of operations and comprehensive loss.

The Company also agreed to file a resale registration within 120 days following the closing covering the shares of common stock issued and the shares of common stock underlying the warrants. The Company’s Executive Chairman, and the Company’s Chief Executive Officer played a key role in identifying and securing potential investors for the September 2018 Financing. As a result, the Company did not have to pay a commission to, or incur additional expenses for, a placement agent. In exchange for their services, which were deemed to be outside the scope of their responsibilities as officers and directors of the Company, the Company’s Audit Committee approved payments of $1,460,000 and $480,000 to the Executive Chairman and the Chief Executive Officer, respectively. As of September 30, 2018, $1,380,000 and $120,000 of these payments, respectively, have been earned and are included as general and administrative expenses in the accompanying condensed consolidated statement of operations for the three and nine month periods ended September 30, 2018. The amount payable to the Executive Chairman totaling $1,380,000 is included in “payable to related parties” in the accompanying condensed consolidated balance sheet as of September 30, 2018 and was paid in October 2018. As described in Note 1, in March 2018, the Company entered into securities purchase agreements with certain institutional investors, accredited investors and current stockholders, pursuant to which the Company issued 15,432,091 shares of its common stock with accompanying warrants to purchase 6,172,832 shares of its common stock and received $50 million in gross proceeds in a private placement. The purchase price for each share of common stock and warrant was $3.24. The warrants became exercisable on September 17, 2018 at a $3.69 per share exercise price and will expire on March 21, 2023. The fair value of the warrants issued is $15,062,000, or $2.44 per warrant, calculated using the Black-Scholes-Merton valuation model with a contractual life of 5 years, an assumed volatility of 75.4%, and a risk-free interest rate of 2.69%. The securities purchase agreements and warrants each include additional customary representations, warranties and covenants. The Company filed a resale registration covering the shares of common stock issued and the shares of common stock underlying the warrants on Form S-3 (File No. 333-226206) which became effective on August 8, 2018. Common Stock Sales Agreement On February 23, 2018, the Company entered into a Common Stock Sales Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC (“HCW”). Pursuant to the terms of the Sales Agreement, the Company may sell from time-to-time, at its option, shares of the Company’s common stock through HCW, as sales agent, with an aggregate sales price of up to $25 million (the “Shares”). Any sales of Shares pursuant to the Sales Agreement will be made under the Company’s effective “shelf” registration statement (the “Registration Statement”) on Form S-3 (File No. 333-222046) which became effective on December 22, 2017 and the related prospectus supplement and the accompanying prospectus, as filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2018. In March 2018, the Company issued 143,248 Shares under the Sales Agreement resulting in net proceeds to the Company of approximately $475,000. As of September 30, 2018, approximately $24.5 million remained available under the Sales Agreement.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	11. Net Loss Per Share Net loss per share (basic and diluted) was computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding. Outstanding stock options and warrants totaling 18,384,932 and 13,425,608 as of September 30, 2018, respectively, were anti-dilutive and, therefore, were not included in the computation of weighted average shares used in computing diluted loss per share.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	12. Stock-Based Compensation and Warrants The Company has adopted incentive and nonqualified stock option plans for executive, scientific and administrative personnel of the Company as well as outside directors and consultants. In June 2018, the Company’s stockholders approved an amendment to the 2011 Long-Term Incentive Plan, increasing the number of shares of common stock reserved for issuance from 14,230,000 to 20,230,000 to be available for grants and awards. As of September 30, 2018, there are 18,384,932 shares issuable under options previously granted and currently outstanding, with exercise prices ranging from $0.86 to $8.23. Options granted under the plans generally vest over periods varying from immediately to one to five years, are not transferable and generally expire ten years from the date of grant. As of September 30, 2018, 6,878,610 shares remained available for grant under the Company’s 2011 Long-Term Incentive Plan. On March 13, 2018, upon the recommendation of the Compensation Committee of the Board of Directors (the “Board”), the Board approved a grant of stock options to the Company’s Executive Chairman exercisable for 1 million shares of common stock that will vest and become exercisable on the first anniversary date of the grant. In addition, the Board approved the grant of a performance-based option covering 4 million shares of common stock that will vest if, within 18 months of the date of grant, specific operational and strategic milestones are achieved. Both grants were approved by the Company’s stockholders at the 2018 Annual Meeting of Stockholders. The Company records compensation expense associated with stock options and other equity-based compensation in accordance with provisions of authoritative guidance. Compensation costs are recognized over the requisite service period, which is generally the option vesting term of up to five years. Awards with performance conditions are expensed when it is probable that the performance condition will be achieved. There was minimal expense recorded for share awards with performance conditions during the nine months ended September 30, 2018 and 2017. The Company’s net loss for the nine months ended September 30, 2018 and 2017 includes $3,517,493 and $516,237, respectively, of non-cash compensation expense related to the Company’s share-based compensation awards. The compensation expense related to the Company’s share-based compensation arrangements is recorded as components of general and administrative expense and research and development expense, as follows: Nine Month Period ended September 30, 2018 2017 Research and development $ 232,230 $ 225,342 General and administrative 3,285,263 290,895 Share-based compensation expense $ 3,517,493 $ 516,237 Net share-based compensation expense, per common share: Basic and diluted $ 0.04 $ 0.01 The Company uses the Black-Scholes-Merton valuation model to estimate the fair value of service based and performance-based stock options granted to employees. Option valuation models, including Black-Scholes-Merton, require the input of highly subjective assumptions, and changes in the assumptions used can materially affect the grant date fair value of an award. Following are the weighted-average assumptions used in valuing the stock options granted to employees during the nine-month periods ended September 30, 2018 and 2017: Nine Month Period ended September 30, 2018 2017 Expected volatility 78.79 % 78.92 % Risk free interest rate 2.80 % 1.97 % Expected term of option 5.77 years 6.34 years Expected dividend yield 0.00 % 0.00 % The weighted average fair value of stock options granted during the nine-month periods ended September 30, 2018 and 2017 were $4.51 and $0.73, respectively. A summary of the Company's stock option plans and of changes in options outstanding under the plans during the nine-month period ended September 30, 2018 is as follows: Number of Options Weighted Average Exercise Price Outstanding at January 1, 2018 11,585,315 $ 1.42 Exercised (156,283 ) $ 1.65 Granted 7,286,000 $ 4.02 Expired (279,970 ) $ 1.50 Forfeited (50,130 ) $ 3.28 Outstanding at September 30, 2018 18,384,932 $ 2.44 Exercisable at September 30, 2018 8,753,696 $ 1.59 Cash received from option exercises under all share-based payment arrangements for the nine months ended September 30, 2018 was $257,948. There were no option exercises during the nine months ended September 30, 2017. Warrants Warrants issued generally expire after 2-5 years from the date of issuance.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	13. Income Taxes At December 31, 2017, the Company had a $3.2 million unrecognized tax benefit. The Company recorded a full valuation allowance on the net deferred tax asset recognized in the consolidated financial statements as of December 31, 2017. During the nine months ended September 30, 2018, there were no material changes to the measurement of unrecognized tax benefits in various taxing jurisdictions. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The tax returns for all years in the Company’s major tax jurisdictions are not settled as of September 30, 2018. Due to the existence of tax attribute carryforwards (which are currently offset by a full valuation allowance), the Company treats all years’ tax positions as unsettled due to the taxing authorities’ ability to modify these attributes.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	15. New Accounting Pronouncements The Company has implemented all new accounting pronouncements that are in effect and that may impact the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 supersedes existing lease guidance, including Accounting Standards Codification (ASC) 840 - Leases . Among other things, the new standard requires recognition of a right-of-use asset and liability for future lease payments for contracts that meet the definition of a lease. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. The standard must be applied using a modified retrospective approach. The Company is completing its evaluation of the effect of the adoption of this ASU and tentatively expects that the adoption will result in an increase to both assets and liabilities on the consolidated balance sheet, with no significant effects on operating results. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842) Targeted Improvements , which offers a transition option to entities adopting the new lease standard. Under the transition option, entities can recognize a cumulative effect adjustment to the opening balance of retained earnings of the year in which the new lease standard is adopted, rather than in the earliest period presented in their financial statements. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business (Topic 805). The amendments in the update provide a screen to determine when a set is not a business. If the screen is not met, the amendments in the update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. Lastly, the amendments in the update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. The ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017; earlier adoption is permitted under certain criteria. The Company adopted this ASU on January 1, 2018. While this ASU did not have a material effect on the Company’s financial statements on the date of adoption, the Company did follow the new guidance in determining that its acquisition of ANDAs from Sandoz, Inc. in January 2018 was an asset acquisition (see Note 2). In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718) Scope of Modification Accounting . ASU 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted ASU 2017-09 in the first quarter of 2018 and the adoption of this ASU did not have a material effect on the consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718) Improvements to Nonemployee Share-Based Payment Accounting which includes updated guidance for share-based payment awards issued to non-employees. The updated standard aligns the accounting for share-based payment awards for non-employees with employees, except for guidance related to the attribution of compensation costs for non-employees. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods for public business entities, with early adoption permitted. The Company is considering early adopting this standard in the fourth quarter of 2018. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. There are no other recently issued accounting pronouncements that are expected to have a material effect on the Company's financial position, results of operations or cash flows.
