This pioneering work led to the development of roxadustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) and pamrevlumab, a fully human monoclonal antibody that inhibits the activity of connective tissue growth factor, or CTGF, a critical mediator in the progression of fibrosis and related serious diseases.&nbsp;&nbsp;&nbsp;&nbsp;</p>

The company applies its pioneering expertise in hypoxia-inducible factor (HIF), connective tissue growth factor (CTGF) biology, and clinical development to advance innovative medicines for the treatment of anemia, fibrotic disease, and cancer. Roxadustat, the company&#8217;s most advanced product candidate, is an oral small molecule inhibitor of HIF prolyl hydroxylase (HIF-PH) activity. Together with our collaboration partners Astellas and AstraZeneca, preparation for regulatory submissions for the treatment of anemia in chronic kidney disease (CKD) to the U.S. FDA, the EMA, and other competent authorities is underway. Roxadustat is approved for treatment of anemia associated with CKD in China in both dialysis-dependent and non-dialysis-dependent CKD patients. Our partner Astellas submitted an NDA for the treatment of anemia in CKD patients on dialysis in Japan in September 2018, which is currently under review by the Pharmaceuticals and Medical Devices Agency (PMDA). Roxadustat is in Phase 3 clinical development in the U.S. and Europe and in Phase 2/3 development in China for anemia associated with myelodysplastic syndromes (MDS). Pamrevlumab, an anti-CTGF human monoclonal antibody, is in Phase 3 clinical development for the treatment of idiopathic pulmonary fibrosis (IPF) and for the treatment of pancreatic cancer. Pamrevlumab is also currently in a Phase 2 trial for Duchenne muscular dystrophy (DMD). FibroGen is also developing a biosynthetic cornea in China.
