Description of intervention(s) / exposure
Treatment: Drugs - Vadadustat
Treatment: Drugs - Darbepoetin alfa

Experimental: Vadadustat -

Active comparator: Darbepoetin alfa -


Treatment: Drugs: Vadadustat
Oral dose administered once daily for =36 weeks. Dose adjustment based on hemoglobin level as defined in the protocol.

Treatment: Drugs: Darbepoetin alfa
Subcutaneous or intravenous dose administered for =36 weeks. Initial dose based on the current package insert for investigational sites in the United States (US), and the Summary of Product Characteristics for all other investigational sites (non-US) for adult participants with chronic kidney disease not on dialysis. For participants already on Darbepoetin alfa, the initial dosing regimen in the study was based on the prior dosing regimen.
