Anemia Studies in Chronic Kidney Disease (CKD): Erythropoiesis Via a Novel Prolyl Hydroxylase Inhibitor (PHI) Daprodustat-in Incident Dialysis (ASCEND-ID)

Completed · Phase 3

Conditions studied: Anaemia

In brief

Who can join

Age: 18 and older, up to 99. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 18 to 99 years of age inclusive.
• Planning to start chronic dialysis within the next 6 weeks (from the date of the screening visit) OR have started and received dialysis (as specified below) for end-stage renal disease for a maximum of <=90 days immediately prior to randomization and is not expected to stop dialysis during the duration of the trial: HD >=2 times per week or PD >=4 times per week including incremental schedule; subjects on continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) are eligible.
• Hemoglobin concentration as measured by HemoCue (range inclusive): 8 to 10.5 g/dL (5-6.5 millimoles per liter [mmol/L]) at screening and 8-11.0 g/dL (5 to 6.8 mmol/L) at randomization.
• Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in this protocol.

You may not qualify if…

• Planned living-related or living-unrelated kidney transplant during the study.
• Ferritin: <=100 nanograms per milliliter (ng/mL) (<=100 micrograms per liter [mcg/L]) at screening or after IV iron supplementation.
• Transferrin saturation (TSAT): <=20% at screening or after IV iron supplementation.
• Vitamin B12 (cobalamin): Below the lower limit of the reference range at screening or after vitamin B12 supplementation.
• Folate: <2.0 ng/mL (<4.5 nanomoles per liter [nmol/L]) at screening.
• Aplasias: History of bone marrow aplasia or pure red cell aplasia (PRCA).
• Other causes of anemia: Untreated pernicious anemia, thalassemia major, sickle cell disease, or myelodysplastic syndrome.
• Gastrointestinal (GI) bleeding: Evidence of actively bleeding gastric, duodenal, or esophageal ulcer disease or clinically significant GI bleeding <=10 weeks prior to screening through to randomization (Day 1).
• Use of any Erythropoiesis-stimulating agent (ESA) treatment within 8 weeks prior to screening except for limited use as part of dialysis initiation. Note : Limited use is defined as no more than 6 weeks of short acting ESA (rhEPO or biosimilars; maximum of 20000 unit total) or long acting ESA (darbepoetin alfa [maximum of 100 mcg total] or methoxy polyethylene glycol-epoetin beta [maximum of 125 mcg total]) received before or after starting dialysis.
• Myocardial infarction or acute coronary syndrome: <=10 weeks prior to screening through to randomization (Day 1).
• Stroke or transient ischemic attack: <=10 weeks prior to screening through to randomization (Day 1).
• Chronic Class IV heart failure, as defined by the New York Heart Association (NYHA) functional classification system.
• Current uncontrolled hypertension as determined by the Investigator that would contraindicate the use of rhEPO.
• QT correction using Bazett's (QTcB) (Day 1): QTcB >500 milliseconds (msec), or QTcB >530 msec in subjects with bundle branch block. There is no QTc exclusion for subjects with a predominantly ventricular paced rhythm.
• Liver disease (any one of the following): 1. Alanine transaminase (ALT) >2 times upper limit of normal (ULN) (screening only). 2. Bilirubin >1.5 times ULN (screening only) (NOTE: Isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). 3. Current unstable liver or biliary disease per investigator assessment, generally defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis. NOTE: Stable chronic liver disease (including asymptomatic gallstones, chronic hepatitis B or C, or Gilbert's syndrome) are acceptable if subject otherwise meets entry criteria.
• History of malignancy within the 2 years prior to screening through to randomization (Day 1), or currently receiving treatment for cancer, or complex kidney cyst (i.e. Bosniak Category II F, III or IV) >3 centimeter (cm). The only exception is localized squamous cell or basal cell carcinoma of the skin that has been definitively treated >=10 weeks prior to screening.
• History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product or to darbepoetin alfa.
• Use of strong Cytochrome P4502C8 (CYP2C8) inhibitors (example gemfibrozil) or strong CYP2C8 inducers (example rifampin/rifampicin).
• Use of other investigational agent or device prior to screening through to randomization (Day 1). At screening, this exclusion applies to use of the investigational agent within 30 days or within five half-lives (whichever is longer).
• Any prior treatment with daprodustat for treatment duration of >30 days.
• Females only: Subject is pregnant [as confirmed by a positive serum human chorionic gonadotropin (hCG) test for females of reproductive potential (FRP) only], subject is breastfeeding, or subject is of reproductive potential and does not agree to follow one of the contraceptive options in the List of Highly Effective Methods for Avoiding Pregnancy.
• Any other condition, clinical or laboratory abnormality, or examination finding that the investigator considers would put the subject at unacceptable risk, which may affect study compliance (example intolerance to rhEPO) or prevent understanding of the aims or investigational procedures or possible consequences of the study.
