FibroGen (NASDAQ:FGEN) received an approval from the Chinese Food and Drug Administration (CFDA) for a Phase 2/3 clinical trial of roxadustat in anemia associated with lower risk myelodysplastic syndromes.
As quoted in the press release:

FibroGen and AstraZeneca (NYSE:AZN) are collaborating on the development and commercialization of roxadustat in China, the U.S., and other major markets. FibroGen is conducting all clinical trials and regulatory submissions in both the U.S. and China, and will retain all regulatory licenses and manufacturing permits in China.
This Phase 2/3 clinical trial will evaluate the safety and efficacy of roxadustat in non-transfusion dependent, lower risk MDS patients with anemia. The initial open-label portion of the study is expected to enroll up to 40 patients, with 135 patients planned for the randomized, double-blind, placebo-controlled Phase 3 portion of the study, in which subjects will be randomized 2:1 to receive roxadustat or placebo three-times-weekly (TIW) for 26 weeks. The Company expects to initiate this Phase 2/3 study in the second half of 2017.
In addition, the Company anticipates initiating a U.S. Phase 3 MDS clinical trial in the third quarter of 2017. The pivotal U.S. study is a randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of roxadustat for the treatment of anemia in transfusion-dependent lower risk MDS patients.
About MDS Anemia in China
Myelodysplastic syndromes (MDS) are a group of disorders characterized by poorly formed or dysfunctional blood cells, leading to anemia in most patients. Anemia is associated with increased risk of hospitalization, cardiovascular complication, need for blood transfusion, exacerbation of other serious medical conditions, and death. In addition, anemia frequently leads to significant fatigue, cognitive dysfunction, and decreased quality of life. Currently, there is no medicine approved for treating anemia in MDS in China. MDS patients typically rely on repeated blood transfusions; however, in China, due to limited blood supply and challenges in accessing transfusions, anemia in most MDS patients is undertreated.
About Roxadustat
Roxadustat (FG-4592) is a first-in-class, orally administered small molecule in global Phase 3 clinical development as a potential therapy for anemia associated with chronic kidney disease (CKD). Roxadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) that promotes erythropoiesis through increasing endogenous erythropoietin, improving iron regulation, and reducing hepcidin. Administration of roxadustat has been shown in clinical trials to induce coordinated erythropoiesis – increasing red blood cell count while maintaining plasma erythropoietin levels within or near normal physiologic range in multiple subpopulations of CKD patients – including in the presence of inflammation and without a need for supplemental intravenous iron.
Roxadustat is currently advancing through Phase 3 clinical trials worldwide, supported by extensive Phase 2 clinical data demonstrating correction and maintenance of hemoglobin levels in multiple subpopulations of CKD anemia patients. To date, roxadustat has been evaluated in Phase 1 and Phase 2 studies, involving more than 1,400 subjects. Globally, a total of 15 Phase 3 studies, with target enrollment of about 10,000 patients worldwide, are currently being conducted to support independent regulatory approvals of roxadustat in both non-dialysis-dependent and dialysis-dependent CKD patients in the U.S., Europe, Japan, and China. Roxadustat is also entering a Phase 3 clinical trial in the U.S., and a Phase 2/3 in China for treatment of anemia in patients with myelodysplastic syndromes (MDS).
