Organization, Consolidation and Presentation of Financial Statements [Abstract] |
The Company | 1. Th e Company FibroGen, Inc. (“FibroGen” or the “Company”) is a biopharmaceutical company focused on development of novel therapies at the frontiers of cancer biology and anemia. The Company is developing FG-3246, an antibody-drug conjugate targeting CD46, for the treatment of metastatic castration-resistant prostate cancer and potentially other cancers. This program also includes the development of FG-3180, an associated CD46-targeted positron emission tomography (“PET”) biomarker and imaging agent. The Company and its collaboration partners have developed roxadustat (爱瑞卓®, EVRENZO TM), which is currently approved in the People’s Republic of China (“China”), Europe, Japan, and numerous other countries for the treatment of anemia in chronic kidney disease (“CKD”) patients on dialysis and not on dialysis. On February 20, 2025, the Company entered into a share purchase agreement (the “Share Purchase Agreement”) with AstraZeneca Treasury Limited pursuant to which FibroGen and its subsidiary FibroGen China Anemia Holdings, Ltd. agreed to sell all of the issued and outstanding equity interests of FibroGen International (Hong Kong) Ltd. (“FibroGen International”) to AstraZeneca Treasury Limited. AstraZeneca AB (“AstraZeneca”) is the Company’s long-time commercialization partner for roxadustat in greater China and South Korea. This sale includes all of FibroGen’s roxadustat assets in China, including FibroGen International’s subsidiary FibroGen (China) Medical Technology Development Co., Ltd and its 51.1% interest in Beijing Falikang Pharmaceutical Co. Ltd (“Falikang”). The transaction is expected to close by mid-2025, and is subject to customary closing conditions and closing deliverables, including receipt of regulatory approval from the China State Administration for Market Regulation. FibroGen has retained the rights to roxadustat in the United States of America (“U.S.”), Canada, Mexico, and in all markets not held by AstraZeneca or licensed to Astellas Pharma Inc. (“Astellas”). Astellas is commercializing roxadustat (EVRENZO TM) in Europe and Japan to treat anemia under two development and commercialization license agreements: one for Japan, and one for Europe, the Commonwealth of Independent States, the Middle East and South Africa. The Company continues to evaluate a development plan for roxadustat in anemia associated with lower-risk myelodysplastic syndrome, a high-value indication with significant unmet medical need.
