Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Risks and Uncertainties	Basis of Presentation and Risks and Uncertainties Basis of Presentation The accompanying unaudited interim consolidated financial statements of MacroGenics, Inc. (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that the management of the Company believes are necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period. The accompanying unaudited interim consolidated financial statements include the accounts of MacroGenics, Inc. and its wholly owned subsidiaries, MacroGenics UK Limited and MacroGenics Limited. All intercompany accounts and transactions have been eliminated in consolidation. These consolidated financial statements and related notes should be read in conjunction with the financial statements and notes thereto included in the Company's 2019 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 25, 2020. Risks and Uncertainties The Company is subject to additional risks and uncertainties due to the COVID-19 pandemic. To date, although there has been some negative impact on the Company's business and operations, including, for example, slowed clinical trial enrollment, the Company has been able to mitigate against more severe impacts of COVID-19 on its business and operations. However, the COVID-19 pandemic could have a more significant negative impact on the Company's business in the future depending on the depth of the effects and the duration of the crisis. The COVID-19 pandemic is an evolving situation and the Company continues to monitor its business very closely to try and mitigate any potential impacts. Significant delays in the timing of the Company's clinical trials and in regulatory reviews could adversely affect its ability to commercialize the product candidates in the Company's pipeline. Notwithstanding the foregoing, the Company cannot precisely predict the impact that COVID-19 will have in the future due to numerous uncertainties, including the severity of the disease, the duration of the outbreak, actions that may be taken by governmental authorities, and the impact to the business of the Company's supply chain. Given these uncertainties, COVID-19 could disrupt the business of certain of the Company's collaborators and impact the Company's business operations and its ability to execute on the Company's associated business strategies and initiatives, and adversely impact the Company's consolidated results of operations and/or the Company's financial condition in the future. The Company will continue to closely monitor and evaluate the nature and extent of the impact of COVID-19 to its business, consolidated results of operations, and financial condition.
