Roxadustat Approved in Japan for the Treatment of Anemia Associated with Chronic Kidney Disease in Dialysis Patients

28 Days ago

SAN FRANCISCO and TOKYO, Sept. 20, 2019 (GLOBE NEWSWIRE) -- FibroGen, Inc. (Nasdaq: FGEN, Interim CEO: James A. Schoeneck, “FibroGen”) and Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., “Astellas”) today announced that Japan’s Ministry of Health, Labour and Welfare (MHLW) approved Evrenzo® (generic name: roxadustat; tradename Evrenzo® in Japan) for the treatment of anemia associated with chronic kidney disease (CKD) in dialysis patients.

Roxadustat is a first-in-class orally administered inhibitor of hypoxia-inducible factor (HIF) prolyl­hydroxylase that corrects anemia by a mechanism of action that is different from that of erythropoiesis-stimulating agents (ESAs). As a HIF-PH inhibitor, roxadustat activates a response that occurs naturally when the body responds to reduced oxygen levels in the blood. The response activated by roxadustat involves the regulation of multiple, complementary processes to promote erythropoiesis and increase the blood’s oxygen-carrying capacity.

"Evrenzo® is a valuable new treatment option for dialysis patients with CKD anemia,” said Bernhardt G. Zeiher, M.D., Chief Medical Officer, Astellas. “Astellas is committed to improving the health of people worldwide and expanding treatment options, especially within the dialysis community where there is high-unmet need. We are delighted to bring this important new treatment option to both patients suffering from, and healthcare professionals treating, this debilitating condition.”

CKD anemia can severely worsen the outcomes of kidney disease, increasing the rate of progression to renal failure1 and the likelihood of cardiovascular complications.2 It also significantly reduces patients’ quality of life and their cognitive ability.3 Reaching and maintaining target hemoglobin levels can present challenges and roxadustat provides an alternative therapeutic option.

“We appreciate the commitment and focus of our partner Astellas as we work together to bring a new therapy to CKD anemia patients on dialysis in Japan,” said K. Peony Yu, M.D., Chief Medical Officer, FibroGen. “With this approval in Japan, NDA approval in China, and EU MAA and U.S. NDA preparations underway, we are another step closer to our goal of addressing the significant unmet medical need of patients living with anemia associated with CKD, worldwide.”

The approval is based on four Phase 3 studies conducted in CKD anemia patients on dialysis in Japan.4,5,6,7 The studies demonstrated that roxadustat was effective at raising hemoglobin and that it was well-tolerated. This marks the first approval for roxadustat through the Astellas and FibroGen collaboration.

About Chronic Kidney Disease (CKD) and Anemia
CKD is a progressive loss of kidney function caused by damage to the kidneys resulting from conditions such as hypertension, diabetes, or immune-regulated inflammatory conditions.8 Worldwide, more than 1 in 10 people are living with CKD.9 In Japan, specifically, the prevalence of CKD has increased significantly over time.10 Although CKD can occur at any age, it becomes more common in aging populations, and the prevalence is increasing. CKD is a critical worldwide healthcare issue that represents a large and growing unmet medical need.

Anemia is a common early complication of CKD,11 affecting approximately 20% of patients with CKD.12 It results from the failing kidneys’ diminished ability to produce erythropoietin that stimulates red blood cell production from the bone marrow, and is associated with significant morbidity and mortality in dialysis and non-dialysis populations, increasing in both prevalence and severity as kidney disease worsens.13 CKD anemia increases the risk of adverse cardiovascular events, worsens renal outcomes and negatively impacts patients’ quality of life.14,15 In addition, CKD can be both a cause and a consequence of cardiovascular disease and is now a critical worldwide healthcare issue that represents a large and growing unmet medical need.

About Roxadustat
In addition to receiving approval from the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan, roxadustat is approved in China for treatment of anemia associated with CKD in both dialysis-dependent and non-dialysis-dependent CKD patients. U.S. NDA and EU MAA preparation is underway. Roxadustat is also 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. For information about roxadustat studies, please visit www.clinicaltrials.gov at: https://clinicaltrials.gov/ct2/results?term=roxadustat&Search=Search.

Astellas and FibroGen are collaborating on the development of roxadustat for the potential treatment of anemia in territories including Japan, Europe, 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, and other markets.
