SAN FRANCISCO, Oct. 14, 2020 (GLOBE NEWSWIRE) -- FibroGen, Inc. (Nasdaq: FGEN) and its partners, AstraZeneca (LSE/STO/Nasdaq: AZN) and Astellas Pharma Inc. (TSE: 4503), will present new analyses from the global Phase 3 program at the upcoming American Society of Nephrology (ASN) Kidney Week 2020 Reimagined , assessing the potential of roxadustat, a first-in-class orally-administered hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, to revolutionize the treatment of anemia in patients with chronic kidney disease (CKD). The virtual congress will take place October 22-25, 2020. FibroGen and its partners will present 42 abstracts, including 2 late-breaker poster presentations, and 10 which have been accepted for oral presentation.

Twenty-eight presentations on roxadustat for the treatment of anemia associated with CKD will further demonstrate the depth and breadth of the roxadustat global Phase 3 development program and build on the known clinical profile of roxadustat in treating a broad spectrum of CKD patients. Another 12 presentations on CKD anemia epidemiology and disease state outline the burden of anemia on CKD patients and their unmet medical need for innovative therapies. In addition, two late-breaking poster presentations will explore associations between cardiovascular safety and hemoglobin levels achieved with roxadustat in both non-dialysis-dependent (NDD) and dialysis-dependent (DD) CKD patients.

“Our roxadustat clinical data at ASN Kidney Week 2020 Reimagined demonstrate consistent efficacy and positive safety results across the continuum of chronic kidney disease patients with anemia, adding to the established body of evidence highlighting roxadustat as a potential foundational treatment for this condition affecting millions of patients,” said Enrique Conterno, Chief Executive Officer, FibroGen. “We thank the investigators, study site staff, and patients who participated in the global roxadustat development program.”

Abstracts assessing the potential clinical profile for use of roxadustat for anemia treatment in CKD patients will include:

• Red Blood Cell ( RBC ) Transfusion R eduction
  Abstracts on the potential of roxadustat to reduce the need for RBC transfusions across the continuum of patients with anemia in CKD include:
  

• Congestive Heart F ailure (CHF) Hospitalization
  Abstract comparing the rates of hospitalization due to CHF, a common and serious comorbidity in CKD patients, between roxadustat and comparators:

• Additional Safety
  Abstracts addressing the safety profile of roxadustat include:
  

• Efficacy and Safety
  Abstracts building on the known efficacy and safety profile of roxadustat for treatment of anemia across the continuum of CKD severity in patient subgroups with different comorbidities, dialysis status or dialysis modality in both NDD and DD CKD, include:
  

• Efficacy and Safety of Roxadustat Versus D arbepoetin Alfa
  Abstract on the primary results of a clinical trial on efficacy and safety of roxadustat in comparison to darbepoetin alfa in non-dialysis dependent patients (DOLOMITES):
  

• Inflammation and Iron
  Abstracts assessing roxadustat efficacy regardless of inflammation status as well as impact on iron homeostasis:
  

About Anemia Associated with CKD
Chronic kidney disease (CKD) is generally a progressive disease characterized by gradual loss of kidney function that may eventually lead to kidney failure or end stage renal disease, requiring dialysis or kidney transplant. CKD is estimated to occur in approximately 10-12% of adults worldwide and is predicted to become the fifth most common cause of premature death globally by 2040.

Anemia, a serious medical condition in which patients have insufficient red blood cells and low levels of hemoglobin, is a common early complication of CKD, affecting approximately 20% of CKD patients. Anemia in CKD is associated with an increased risk of hospitalization, cardiovascular complications, and death, and can also cause significant fatigue, cognitive dysfunction and reduced quality of life. Blood transfusions are used for treating severe anemia, however, they may reduce a patient’s opportunity for kidney transplant and can increase the risk of infection and/or complications such as heart failure and allergic reactions.

About Roxadustat
Roxadustat is a first-in-class, oral small molecule HIF-PH inhibitor that promotes erythropoiesis through increased endogenous production of erythropoietin; improved iron absorption, transport, and mobilization; and downregulation of hepcidin, which helps to overcome the negative impact of inflammation on hemoglobin synthesis and red blood cell production. Roxadustat is approved in China for the treatment of anemia in adult patients with CKD, both on dialysis and not on dialysis. In Japan, roxadustat is approved for the treatment of anemia in CKD patients on dialysis, and a supplemental NDA for the treatment of anemia in CKD patients not on dialysis is under regulatory review. The roxadustat NDA for the treatment of anemia in CKD in patients both on dialysis and not on dialysis is under review by the U.S. Food and Drug Administration with a Prescription Drug User Fee Act date of December 20, 2020. The Marketing Authorization Application for roxadustat for the treatment of anemia in CKD in patients both on dialysis and not on dialysis was filed by our partner Astellas and accepted by the European Medicines Agency for review on May 21, 2020. Roxadustat is also in clinical development for anemia associated with myelodysplastic syndromes (MDS) and chemotherapy-induced anemia (CIA).

Astellas and FibroGen are collaborating on the development and commercialization of roxadustat for the treatment of anemia in territories including Japan, Europe, the Commonwealth of Independent States, the Middle East, and South Africa. AstraZeneca and FibroGen are collaborating on the development and commercialization of roxadustat for the treatment of anemia in the U.S., China, and other markets in the Americas and in Australia/New Zealand, as well as Southeast Asia. At ASN Kidney Week 2020 Reimagined, roxadustat data will be sponsored and presented by Astellas, AstraZeneca, and FibroGen.
