Notes to Financial Statements
Basis of Accounting [Text Block]	Note 2 – Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of the Company’s management, the accompanying condensed consolidated financial statements contain all adjustments (consisting of normal recurring accruals and adjustments) necessary for fair statement of its financial position, results of operations and cash flows of the Company at the dates and for the periods indicated. Interim results are not necessarily indicative of results for the full fiscal year. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 24, 2023. The Company has experienced net losses since its inception and has an accumulated deficit of $631.5 million and $577.1 million as of June 30, 2023 and December 31, 2022, respectively. The Company expects to incur losses and have negative net cash flows from operating activities as it executes on its strategy including engaging in further research and development activities, particularly conducting non-clinical studies and clinical trials. The success of the Company depends on the ability to successfully commercialize its technologies to support its operations and strategic plan. In accordance with the accounting guidance related to the presentation of financial statements, management evaluates whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for the next 12 months from the date the financial statements are issued. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern, and do not include any adjustments relating to the carrying amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern. The Company’s ability to continue as a going concern is expected to be impacted by its ability to raise additional capital to fund its operations, produce cash inflows from Jelmyto product sales and develop UGN-102. On July 26, 2023, the Company entered into a private placement transaction with certain institutional and other accredited investors pursuant to which the Company agreed to sell its ordinary shares and pre-funded warrants to purchase ordinary shares to the investors, for aggregate gross proceeds of $120.0 million. See Note 19 for further discussion regarding the private placement transaction. Based on the Company's cash, cash equivalents and marketable securities as of June 30, 2023, together with management’s cash flow projections and the net proceeds to the Company from its private placement transaction in July 2023, the Company believes that it has sufficient cash and cash equivalents to fund its operations beyond one year from the issuance of these financial statements. The Company will need to raise additional capital in the future. There can be no assurances that the Company will be able to secure such additional financing if at all, or on terms that are satisfactory to the Company, and that it will be sufficient to meet its needs. In the event the Company is not successful in obtaining sufficient funding, this could force us to delay, limit, or reduce our product development, commercialization efforts or other operations.
