FibroGen Provides Regulatory Update on Roxadustat
SAN FRANCISCO, Dec. 18, 2020 (GLOBE NEWSWIRE) -- FibroGen, Inc. (Nasdaq: FGEN) today announced that the U.S. Food and Drug Administration (FDA) has extended the review period of the New Drug Application (NDA) for roxadustat for the treatment of anemia of chronic kidney disease (CKD) by three months. The updated Prescription Drug User Fee Act (PDUFA) action date is March 20, 2021.
The FDA is close to finalizing its review of the NDA and FibroGen is submitting additional analyses of existing roxadustat clinical data, which require an extension of the original PDUFA date.
“FibroGen is working closely with the FDA, in collaboration with our partner, AstraZeneca, to support the final review of the new drug application for roxadustat,” said Enrique Conterno, Chief Executive Officer, FibroGen. “There is significant unmet medical need for the treatment of anemia of CKD, and we are committed to bringing roxadustat to patients in the U.S. as soon as possible.”
Roxadustat, an oral small molecule hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, is the first HIF-PH inhibitor accepted by the FDA for review for the treatment of anemia of CKD. The NDA for roxadustat is based on positive results from a global Phase 3 program encompassing more than 8,000 patients.
About Anemia of 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 of 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, an oral medicine, is the first in a new class of medicines called HIF-PH inhibitors that promotes erythropoiesis, or RBC production, through increased endogenous production of erythropoietin; improved iron absorption and mobilization; and downregulation of hepcidin. Roxadustat is also in clinical development for anemia associated with MDS syndromes and for chemotherapy-induced anemia.
Roxadustat is approved in China, Japan, and Chile for the treatment of anemia of CKD in adult patients on dialysis (DD) and not on dialysis (NDD). In Europe, the Marketing Authorization Application for roxadustat for the treatment of anemia in CKD in NDD and DD patients was filed by Astellas Pharma Inc. (Astellas) and accepted by the European Medicines Agency for review in May 2020. Several other licensing applications for roxadustat have been submitted by Astellas and AstraZeneca to regulatory authorities across the globe, which are currently in review.
Astellas and FibroGen are collaborating on the development and commercialization of roxadustat for the potential treatment of anemia in territories including Japan, Europe, Turkey, Russia and the Commonwealth of Independent States, the Middle East and South Africa. FibroGen and AstraZeneca are collaborating on the development and commercialization of roxadustat for the potential treatment of anemia in the U.S., China, other markets in the Americas and in Australia/New Zealand as well as Southeast Asia.
