Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Vadadustat | Participants were randomized to receive Vadadustat at an initial oral dose of 300 milligrams per day (mg/day). Thereafter, Vadadustat was taken once daily on an outpatient basis. Up-and-down titration to 150, 300, 450, and 600 mg (available tablet strength was administered as the appropriate number of 150 mg tablets) was allowed during the study based on hemoglobin (Hb) level measurements to maintain target Hb levels. | 180 | 878 | EG000 |
| Group 2 | Darbepoetin Alfa | Participants were randomized to Darbepoetin alfa at an initial dose that was based on the current package insert for investigational sites in the United States (US), and the Summary of Product Characteristics (SmPC) for all other investigational sites (non-US) for adult participants with chronic kidney disease not on dialysis. | 168 | 870 | EG001 |
