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 | Daprodustat | Participants received daprodustat film-coated tablets with titrated dose levels ranging from 1, 2, 4, 6, 8, 10, 12, 16, and 24 milligrams (mg) orally once daily for up to 52 weeks. Study treatment was dose-titrated to achieve and maintain hemoglobin (Hgb) in the target range (10 to 11 grams per deciliter \[g/dL\]). | 86 | 133 | OG000 |
| Group 2 | Darbepoetin Alfa | Participants received darbepoetin alfa as prefilled syringes (PFS) for subcutaneous or intravenous (IV) injection with 4-weekly total dose levels ranging from 20, 30, 40, 60, 80, 120, 160, 200, 300 and 400 microgram (mcg) for 52 weeks. Study treatment was dose-titrated to achieve and maintain Hgb in the target range (10 to 11 g/dL). | 87 | 133 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Hgb Responders (Hgb in the Analysis Range of 10 to 11.5 Grams/Deciliter) During Evaluation Period (Week 28 to Week 52)
- Description
Mean Hgb during the evaluation period was defined as the mean of all evaluable Hgb values during the evaluation period (Week 28 to Week 52) including any evaluable unscheduled Hgb values that were taken during this time period. Hgb responders were defined as number of participants with a mean Hgb during the evaluation period that falls within the Hgb analysis range of 10-11.5 g/dL.
- Time frame
- Weeks 28 to 52
- Population
- ITT Population. Only those participants with data available at the indicated time points were analyzed.
