FibroGen, Inc. (“FibroGen” or the “Company”) is headquartered in San Francisco, California, with subsidiary offices in Beijing and Shanghai, People’s Republic of China (“China”). FibroGen is a leading biopharmaceutical company developing and commercializing a pipeline of first-in-class therapeutics. FibroGen applies its pioneering expertise in hypoxia-inducible factor biology, 2-oxoglutarate enzymology, and connective tissue growth factor biology to advance innovative medicines for the treatment of anemia, fibrotic disease, and cancer. Roxadustat is FibroGen’s most advanced product, an oral small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase activity. Roxadustat is currently approved for use in patients with anemia associated with chronic kidney disease (“CKD”) in China (2019), Japan (2020) and Europe (2021), under the tradename EVRENZO®. Roxadustat is also being commercialized in China for CKD anemia in dialysis and non-dialysis patients under the tradename: 爱瑞卓®. Roxadustat is in Phase 3 clinical development for anemia associated with myelodysplastic syndromes and Phase 2 clinical development for chemotherapy-induced anemia. Pamrevlumab is FibroGen’s first-in-class antibody developed to inhibit the activity of connective tissue growth factor, a common factor in fibrotic and fibro-proliferative disorders characterized by persistent and excessive scarring that can lead to organ dysfunction and failure. In the second quarter of 2021, the Food and Drug Administration (“FDA”) granted both Rare Pediatric Disease designation and Fast Track designation for pamrevlumab for the treatment of patients with Duchenne Muscular Dystrophy. In addition, the FDA has granted Orphan Drug Designation to pamrevlumab for the treatment of idiopathic pulmonary fibrosis, locally advanced unresectable pancreatic cancer, and Duchenne Muscular Dystrophy. Pamrevlumab has also received Fast Track designation from the FDA for the treatment of both idiopathic pulmonary fibrosis and locally advanced unresectable pancreatic cancer. FibroGen has a pipeline of late-stage clinical programs as well as pre-clinical drug candidates at various stages of development that include both small molecules and biologics.
