Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Mean Change From Baseline in Hemoglobin Levels Over the Evaluation Period (Week 28 to Week 52) | Baseline (Pre-dose on Day 1) and evaluation period (Week 28 to Week 52) | Blood samples were collected from participants for hemoglobin measurements. Hemoglobin during the evaluation period was defined as the mean of all available post-randomization hemoglobin values (on and off-treatment) during the evaluation period (Week 28 to Week 52). For the primary analysis, the missing post-Baseline hemoglobin values were imputed using pre-specified multiple imputations. Baseline value was the latest non-missing pre-dose assessment on or before the randomization date, including those from unscheduled visits. Change from Baseline was defined as the average of post-randomization values during the evaluation period minus Baseline value. Analysis was performed using the Analysis of Covariance (ANCOVA) model with terms for treatment, Baseline hemoglobin, and region. |
| Secondary | Mean Average Monthly On-treatment Intravenous (IV) Iron Dose Per Participant | Day 1 to Week 52 | Average monthly IV iron dose (mg) per participant during Day 1 to Week 52 was determined by calculating the total IV iron dose per participant from Day 1 to Week 52 while the participant was on study treatment and dividing by (the number of days the participant was on study treatment divided by 30.4375 days). Analysis was performed using the ANCOVA model with terms for treatment, Baseline monthly IV iron dose, and region. |
| Secondary | Change From Baseline in Hemoglobin Levels at Week 52 | Baseline (Pre-dose on Day 1) and Week 52 | Blood samples were collected from participants for hemoglobin measurements. Baseline value was the latest non-missing pre-dose assessment on or before the randomization date, including those from unscheduled visits. Change from Baseline was defined as the post-randomization visit value minus Baseline value. Analysis was performed using a mixed model repeated measures (MMRM) model fitted to hemoglobin data collected after Baseline up to Week 52, excluding values collected during the stabilization period (Day 1 to Week 28). The model included factors for treatment, time, region, Baseline hemoglobin and Baseline hemoglobin by time and treatment by time interaction terms. |
| Secondary | Percentage of Time With Hemoglobin in the Analysis Range (10 to 11.5 Grams/Deciliter) Over Evaluation Period (Week 28 to Week 52) | Week 28 to Week 52 | Participants received treatment during the study to achieve or maintain hemoglobin level in the target range. Percentage of time for which hemoglobin level was maintained within the analysis range (10 to 11.5 grams/deciliter) has been presented. |
| Secondary | Number of Hemoglobin Responders in the Hemoglobin Analysis Range (10 to 11.5 Grams/Deciliter) Over Evaluation Period (Week 28 to Week 52) | Week 28 to Week 52 | Mean hemoglobin during the evaluation period was defined as the mean of all evaluable hemoglobin values during the evaluation period (Week 28 to Week 52) including any evaluable unscheduled hemoglobin values that were taken during this time period. Hemoglobin responders were defined as the number of participants with a mean hemoglobin during the evaluation period that falls within the hemoglobin analysis range of 10-11.5 grams/deciliter. |
| Secondary | Percentage of Participants Permanently Stopping Study Treatment Due to Meeting Rescue Criteria | Up to Week 52 | Percentage of participants permanently stopping study treatment due to meeting rescue criteria has been presented. |
| Secondary | Change From Baseline in Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Mean Arterial Pressure (MAP) at Week 52 | Baseline (Week -4 ) and Week 52 | Measurements for SBP, DBP and MAP were taken with the participant in a semi-supine or seated position in the dialysis chair after at least a 5-minute rest period. MAP is the average BP in an individual's arteries during a single cardiac cycle. Baseline value was the latest non-missing pre-dose assessment on or before the randomization date, including those from unscheduled visits. Change from Baseline was defined as the on-treatment visit value minus Baseline value. Analysis was performed using MMRM model with treatment group, time, region, Baseline value, Baseline value\*time, treatment group\*time as variables. |
| Secondary | Change From Baseline in SBP, DBP and MAP at End of Treatment | Baseline (Week -4) and end of treatment (last on-treatment value until Week 52) | Measurements for SBP, DBP and MAP were taken with the participant in a semi-supine or seated position in the dialysis chair after at least a 5-minute rest period. MAP is the average BP in an individual's arteries during a single cardiac cycle. Baseline value was the latest non-missing pre-dose assessment on or before the randomization date, including those from unscheduled visits. Change from Baseline was defined as the last on-treatment visit value minus Baseline value. Analysis was performed using ANCOVA model with terms for treatment group, region and Baseline value. Adjusted mean and standard error have been presented. |
| Secondary | Blood Pressure (BP) Exacerbation Event Rate Per 100 Participant Years | Up to 52 weeks | BP exacerbation event is defined (based on post-dialysis BP) as SBP \>=25 mmHg increased from Baseline or SBP \>=180 mmHg; or DBP \>=15 mmHg increased from Baseline or DBP \>=110 mmHg. The BP exacerbation events per 100 participant years was estimated using the Negative Binomial Model. |
| Secondary | Number of Participants With at Least One BP Exacerbation Event During the Study | Up to 52 weeks | BP exacerbation (based on post-dialysis BP) is defined as: SBP \>= 25 mmHg increased from Baseline or SBP \>=180mmHg; or DBP \>=15 mmHg increase from Baseline or DBP \>=110 mmHg. Number of participants with at least 1 BP exacerbation event have been reported. |
