Further update on US regulatory review of
roxadustat in anaemia of chronic kidney disease

AstraZeneca and FibroGen, Inc. (FibroGen) today announced that the US Food and Drug Administration (FDA) informed FibroGen that it will convene a meeting of the Cardiovascular and Renal Drugs Advisory Committee to review the new drug application for roxadustat. Roxadustat is under regulatory review for the treatment of anaemia of chronic kidney disease (CKD).

AstraZeneca and FibroGen are committed to working with the FDA ahead of the meeting and to bringing roxadustat to patients with anaemia of CKD. A date for the advisory committee meeting has not been determined.

The efficacy and safety of roxadustat, an oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, have been demonstrated in the pivotal Phase III programme including more than 8,000 patients and published in five peer-reviewed journals. 

Roxadustat is approved in China, Japan and Chile for the treatment of anaemia in CKD in non-dialysis dependent (NDD) and dialysis-dependent (DD) adult patients, and is under regulatory review in the EU and other jurisdictions.

Anaemia

Anaemia can be a serious medical condition in which patients have insufficient red blood cells (RBCs) and low haemoglobin levels, a protein in RBCs that carries oxygen to cells throughout the body.¹ Anaemia of CKD is associated with increased risk of hospitalisation, cardiovascular complications and death, frequently causing significant fatigue, cognitive dysfunction and decreased quality of life.^2,3 Severe anaemia is common in patients with CKD, cancer, myelodysplastic syndrome (MDS), inflammatory diseases and other serious illnesses. Anaemia is particularly prevalent in patients with CKD.² CKD affects nearly 700 million patients worldwide and is generally progressive, characterised by gradual loss of kidney function that may eventually lead to kidney failure.⁴

Roxadustat

Roxadustat, an oral medicine, is the first in a new class of treatments called HIF-PH inhibitors that promotes erythropoiesis, or red blood cell production, through increased endogenous production of erythropoietin, improved iron absorption and mobilisation, and reduction of hepcidin. Roxadustat is also in clinical development for anaemia associated with MDS and for chemotherapy-induced anaemia.

Roxadustat is approved in China, Japan (under the name Evrenzo), and Chile for the treatment of anaemia in CKD in NDD and DD adult patients. In Europe, the Marketing Authorisation Application for Evrenzo for the treatment of anaemia in CKD in NDD and DD patients was submitted by Astellas Pharma Inc. (Astellas) and accepted by the European Medicines Agency for review in May 2020.

AstraZeneca and FibroGen are collaborating on the development and commercialisation of roxadustat for the potential treatment of anaemia in the US, China and other countries in the Americas, Australia and New Zealand, as well as Southeast Asia. Astellas and FibroGen are collaborating on the development and commercialisation of roxadustat for the potential treatment of anaemia in Japan, Europe, Turkey, Russia and the Commonwealth of Independent States, the Middle East and South Africa.

Phase III programme

The Phase III programme included more than 8,000 patients and was conducted by AstraZeneca, FibroGen and Astellas. The OLYMPUS, ALPS and ANDES trials evaluated roxadustat compared to placebo in NDD patients. ROCKIES, SIERRAS and HIMALAYAS evaluated roxadustat compared to epoetin alfa in DD and incident dialysis (ID) patients. HIMALAYAS evaluated roxadustat compared to epoetin alfa in ID patients; ROCKIES and SIERRAS included ID patients.
