FibroGen, Inc. (NASDAQ: FGEN) today announced that the U.S. Food and Drug Administration (FDA) has issued a complete response letter regarding the New Drug Application (NDA) for roxadustat for the treatment of anemia of chronic kidney disease (CKD).
SAN FRANCISCO, Aug. 11, 2021 (GLOBE NEWSWIRE) -- FibroGen, Inc., (NASDAQ: FGEN) today announced that the U.S. Food and Drug Administration (FDA) has issued a complete response letter regarding the New Drug Application (NDA) for roxadustat for the treatment of anemia of chronic kidney disease (CKD).
The letter indicates the FDA will not approve the roxadustat NDA in its present form and has requested additional clinical study of roxadustat be conducted, prior to resubmission.
“We are deeply disappointed with this result, and this is an unfortunate day for patients suffering from anemia of CKD in the United States,” said Enrique Conterno, Chief Executive Officer, FibroGen. “Roxadustat is changing the lives of patients around the world, and we and our partner AstraZeneca will discuss next steps in the U.S.”
Roxadustat is approved in China, Japan, Chile, and South Korea for the treatment of anemia of CKD in both non-dialysis-dependent (NDD) and dialysis-dependent (DD) adult patients and has received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP), the European Medicines Agency’s committee responsible for human medicines. The European Commission decision is expected by the end of August.
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 percent 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 percent 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, HIF-PH inhibitors that promote erythropoiesis, or red blood cell 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 myelodysplastic syndromes (MDS) and for chemotherapy-induced anemia (CIA).
Roxadustat is approved in China, Japan, Chile, and South Korea for the treatment of anemia of CKD in adult patients on dialysis (DD) and not on dialysis (NDD). In Europe, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion relating to the use of roxadustat for the treatment of adult patients with symptomatic anemia associated with chronic kidney disease (CKD). Several other licensing applications for roxadustat have been submitted by Astellas and AstraZeneca to regulatory authorities across the globe, and are currently in review.
Astellas and FibroGen are collaborating on the development and commercialization of roxadustat for the potential treatment of anemia of CKD 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 of CKD in the U.S., China, other markets in the Americas, in Australia/New Zealand, and Southeast Asia.
