Safety and Efficacy Study of Roxadustat (FG-4592) for the Treatment of Anemia in End-Stage Renal Disease (ESRD) Newly Initiated Dialysis Participants

Completed · Phase 3

Conditions studied: Anemia in Incident Dialysis Patients

In brief

The purpose of this study is to determine whether roxadustat is safe and effective in the treatment of anemia in participants who have just begun dialysis treatment for ESRD.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participant has been informed of the investigational nature of this study and has given written informed consent in accordance with institutional, local, and national guidelines.
• Receiving HD or PD for ESRD for a minimum of 2 weeks and a maximum of 4 months, prior to randomization.
• Hemodialysis access consisting of an arteriovenous (AV) fistula, AV graft, or tunnelled (permanent) catheter; or PD catheter in use.
• Mean of the two most recent predialysis Hb values during the Screening Period, obtained at least 2 days apart, must be ≤ 10.0 g/dL, with a difference of ≤ 1.3 g/dL between the highest and the lowest values. The last Hb value must be drawn within 10 days prior to randomization.
• Ferritin ≥ 100 nanograms (ng)/milliliter (mL) (≥ 220 picomoles (pmol)/L); participants with ferritin level < 100 ng/mL(<220 pmol/L) during screening, qualify after receiving iron supplement (per local standard of care), without the need to retest ferritin prior to randomization.
• Transferrin saturation ≥ 20%; participants with TSAT level < 20% during screening, qualify after receiving iron supplement (per local standard of care), without the need to retest TSAT prior to randomization.
• Serum folate level, performed within 8 weeks prior to randomization ≥ lower limit of normal (LLN); participants with serum folate level < LLN during screening, qualify after receiving folate supplement (per local standard of care), without the need to retest folate prior to randomization.
• Serum vitamin B12 level, performed within 8 weeks prior to randomization ≥ LLN; participants with vitamin B12 level < LLN during screening, qualify after receiving B12 supplement (per local standard of care), without the need to retest B12 prior to randomization.
• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤ 3 * upper limit of normal (ULN), and total bilirubin ≤ 1.5 * ULN.
• Body weight up to 160 kg (HD participants: dry weight).

You may not qualify if…

• Total duration of prior effective ESA use must be ≤3 weeks within the preceding 12 weeks at the time informed consent is obtained.
• Specific dosing guidance, depending on the type of ESAs, injected IV or SC within 12 weeks prior to start of screening are as follows:
• i) Short-acting ESAs (EPO-alfa or equivalents) - IV: Up to 9 doses, last EPO dose must be ≥2 days prior to start of screening; SC: Up to 3 doses, last EPO dose must be ≥1 week (7 days) prior to start of screening ii) Darbepoetin - IV: Up to 3 doses, last darbepoetin dose must be ≥1 week (7 days) prior to start of screening; SC: Up to 2 doses, last darbepoetin dose must be ≥2 weeks (14 days) prior to start of screening iii) Continuous erythropoietin receptor activator (CERA) IV and SC: Up to 2 doses; last CERA dose must be ≥2 weeks (14 days) prior to start of screening
• Intravenous iron: there is no restriction regarding IV iron use during screening, provided it is administered in accordance with local SOC.
• Red blood cell transfusion within 4 weeks prior to randomization.
• Active, clinically significant infection that could be manifested by white blood cell (WBC) count > ULN, and/or fever, in conjunction with clinical signs or symptoms of infection at the time of randomization.
• History of chronic liver disease (for example, chronic infectious hepatitis, chronic auto-immune liver disease, cirrhosis, or fibrosis of the liver).
• New York Heart Association Class III or IV congestive heart failure at screening.
• Myocardial infarction, acute coronary syndrome, stroke, seizure, or a thromboembolic event within a major vessel (excluding vascular dialysis access) (for example, deep vein thrombosis or pulmonary embolism) within 12 weeks prior to randomization.
• Uncontrolled hypertension, in the opinion of the Investigator, (for example, that requires a change in anti-hypertensive medication) within 2 weeks prior to randomization.
• Renal imaging performed within 12 weeks prior to randomization indicative of a diagnosis or suspicion (for example, complex kidney cyst of Bosniak Category 2 or higher) of renal cell carcinoma.
• History of malignancy, except for the following: cancers determined to be cured or in remission for ≥ 5 years, curatively resected basal cell or squamous cell skin cancers, cervical cancer in situ, or resected colonic polyps.
• Positive for any of the following: human immunodeficiency virus (HIV); hepatitis B surface antigen (HBsAg); or anti-hepatitis C virus antibody (anti-HCV Ab).
• Chronic inflammatory disease that could impact erythropoiesis (for example, systemic lupus erythematosus, rheumatoid arthritis, celiac disease) even if it is currently in remission.
• Known, untreated proliferative diabetic retinopathy, diabetic macular edema, macular degeneration, or retinal vein occlusion (participants who are already blind for the above reasons qualify to participate).
• Known history of myelodysplastic syndrome or multiple myeloma.
• Known hereditary hematologic disease such as thalassemia or sickle cell anemia, pure red cell aplasia, or other known causes for anemia other than chronic kidney disease (CKD).
• Known hemosiderosis, hemochromatosis, coagulation disorder, or a hypercoagulable condition.
• Organ transplant: participants with any of the following:
• Experienced rejection of a transplanted organ within 6 months of transplantation
• Currently on high doses of immunosuppressive therapy (per discretion of the Investigator)
• Scheduled for organ transplantation. Note: being on a waiting list for kidney transplant is not exclusionary
• Anticipated elective surgery, except for vascular access surgery or dialysis catheter placement, that is expected to lead to significant blood loss, or anticipated elective coronary revascularization.
• Active or chronic gastrointestinal bleeding.
• Any prior treatment with roxadustat or a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI).
