Accounting Policies [Abstract] |
Nature of Operations | Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. The Company is registered as an Irish public limited company. The Company’s headquarters are in Dublin, Ireland with operations in Dublin, Ireland and St. Louis, Missouri, United States (“U.S.”). The Company’s lead product candidate, LUMRYZ, also known as FT218, is an investigational once-at-bedtime, extended-release formulation of sodium oxybate for the treatment of cataplexy or excessive daytime sleepiness (“EDS”) in adults with narcolepsy. On July 18, 2022, the U.S. Food and Drug Administration (“FDA”) granted tentative approval to LUMRYZ for this indication. Tentative approval indicates that LUMRYZ has met all required quality, safety, and efficacy standards necessary for approval in the U.S. The Company is primarily focused on obtaining final FDA approval of LUMRYZ. A decision on final FDA approval of LUMRYZ is pending disposition of U.S. Patent No. 8731963 (the “REMS Patent”), which is listed in the FDA’s Orange Book. The decision on final FDA approval could occur on or about the expiration of the REMS Patent on June 17, 2023 or sooner if the patent is earlier removed from the FDA’s Orange Book or a court earlier determines that patent is not infringed, invalid or otherwise unenforceable. The FDA’s tentative approval can be subject to change based on new information that may come to the FDA’s attention between such time as the tentative approval and potential final approval. The Company cannot legally market LUMRYZ in the U.S. until final approval is granted by the FDA. Outside of the Company’s lead product candidate, the Company continues to evaluate opportunities to expand its product portfolio. As of the date of this Quarterly Report, the Company does not have any commercialized products in its portfolio.

The unaudited condensed consolidated balance sheet as of September 30, 2022, which is derived from the prior year 2021 audited consolidated financial statements, and the interim unaudited condensed consolidated financial statements presented herein, have been prepared in accordance with U.S. GAAP, the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by U.S. GAAP for complete financial statements or all the disclosures normally made in an Annual Report on Form 10-K. Accordingly, the unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Company’s 2021 Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (“SEC”) on March 16, 2022.The unaudited condensed consolidated financial statements include the accounts of the Company and subsidiaries, and reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the dates and periods presented. All intercompany accounts and transactions have been eliminated. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period.
