Study Details

Study Description

Brief Summary

The purpose of this study is to confirm the safety and efficacy of Soluble Ferric Pyrophosphate (SFP) dialysate solution in maintaining iron delivery for erythropoiesis in anemic adult patients with chronic kidney disease (CKD) receiving hemodialysis. Efficacy will be measured primarily by the change from baseline in hemoglobin (Hgb).

Condition or Disease Intervention/Treatment Phase
  • Drug: Soluble Ferric Pyrophosphate (SFP)
  • Device: Standard dialysate
Phase 3

Detailed Description

Screening: 2-3 weeks prior to enrollment in Stage 1.

Stage 1 (Run-In): 1-4weeks depending on qualification for Stage 2.

Stage 2 (Randomized Blinded Treatment): 12 months unless withdrawn prematurely.

Outcome Measures

Primary Outcome Measures

  1. Change From Baseline Hemoglobin at End-of-Treatment: Least-Squares Mean [Hgb measured weekly; up to 48 weeks from date of randomization]

    Mean change from baseline Hgb (the average of the three most recent Hgb values preceding randomization) assessments during the last one-sixth of the treatment period for patients who prematurely withdraw from study treatment, but will include a minimum of at least the last two Hgb values. Value is expressed as least-squares mean, along with standard error.

  2. Change From Baseline Hemoglobin at End-of-Treatment: Mean Baseline and End-of-Treatment Hemoglobin [Hgb measured weekly; up to 48 weeks from date of randomization]

    Mean change from baseline Hgb (the average of the three most recent Hgb values preceding randomization) assessments during the last one-sixth of the treatment period for patients who prematurely withdraw from study treatment, but will include a minimum of at least the last two Hgb values. Values expressed are mean baseline and end-of-treatment Hgb, along with the mean difference (standard deviation).

Secondary Outcome Measures

  1. Mean Change in Serum Iron From Pre-Dialysis to Post-Dialysis [Up to 48 weeks from date of randomization]

    The mean difference between the pre-dialysis and post-dialysis serum iron was calculated, using all post-baseline values obtained during Stage 2. Subjects could participate in Stage 2 for up to 48 weeks, provided that they did not complete Stage 2 early due to a protocol-mandated change in anemia management or withdraw from the study entirely for other reasons.

  2. Mean Change in Transferrin Saturation From Pre-Dialysis to Post-Dialysis [Up to 48 weeks from date of randomization]

    The mean difference between the pre-dialysis and post-dialysis TSAT (transferrin) was calculated, using all post-baseline values obtained during Stage 2. Subjects could participate in Stage 2 for up to 48 weeks, provided that they did not complete Stage 2 early due to a protocol-mandated change in anemia management or withdraw from the study entirely for other reasons.

  3. Mean Change in Unsaturated Iron-Binding Capacity (UIBC) From Pre-Dialysis to Post-Dialysis [Up to 48 weeks from date of randomization]

    The mean difference between the pre-dialysis and post-dialysis unsaturated iron binding capacity (UIBC) was calculated, using all post-baseline values obtained during Stage 2. Subjects could participate in Stage 2 for up to 48 weeks, provided that they did not complete Stage 2 early due to a protocol-mandated change in anemia management or withdraw from the study entirely for other reasons.

  4. Red Blood Cell or Whole Blood Transfusion: Number of Patients Who Received a Transfusion [Up to 48 weeks from date of randomization]

    The number of patients requiring red blood cell or whole blood transfusion while in the randomized treatment stage (Stage 2). Patients remained in Stage 2 until they met protocol-defined criteria for Stage 2 completion or until they had participated in Stage 2 for 48 weeks (whichever came sooner). If a patient was transfused, they were withdrawn from Stage 2.

  5. Red Blood Cell or Whole Blood Transfusion: Number of Units Transfused [Up to 48 weeks from date of randomization]

    The total number of units of red blood cells or whole blood that were received by patients while in the randomized treatment stage (Stage 2). This number is the total number of units received across all randomized patients in each treatment group (it is not the average number of units received per patient). Patients remained in Stage 2 until they met protocol-defined criteria for Stage 2 completion or until they had participated in Stage 2 for 48 weeks (whichever came sooner). If a patient was transfused, they were withdrawn from Stage 2.

  6. Percentage of Change From Baseline to End-of-Treatment for: Reticulocyte Hemoglobin Content (CHr), Ferritin, and the Pre-Dialysis Serum Iron Panel [up to 48 weeks from date of randomization]

    A comparison of the lab values at the end-of-treatment (EoT) to baseline was performed, and the percentage of change from baseline was calculated for the following lab parameters: reticulocyte hemoglobin content (CHr), Ferritin, pre-dialysis unbound iron-binding capacity (UIBC), pre-dialysis serum iron, pre-dialysis transferrin, pre-dialysis total iron-binding capacity TIBC), and transferrin saturation (TSAT).

  7. Change From Baseline to End-of-Treatment (EoT) in Pre-Dialysis Unsaturated Iron-Binding Capacity (UIBC), Pre-Dialysis Serum Iron, and Pre-Dialysis Total Iron-Binding Capacity (TIBC) [Up to 48 weeks from date of randomization]

    The Mean Change from Stage 2 Baseline to End-of-Treatment (EoT) in Pre-Dialysis Unsaturated Iron-Binding Capacity (UIBC), Pre-Dialysis Serum Iron, and Pre-Dialysis Total Iron-Binding Capacity (TIBC) will be quantified.

  8. Change From Baseline to End-of-Treatment (EoT) in Reticulocyte Hemoglobin (CHr) [Up to 48 weeks from date of randomization]

    The Mean Change from Stage 2 Baseline to End-of-Treatment (EoT) in Reticulocyte Hemoglobin (CHr)

  9. Change From Baseline to End-of-Treatment (EoT) in Ferritin [Up to 48 weeks from date of randomization]

    The Mean Change from Stage 2 Baseline to End-of-Treatment (EoT) in Ferritin

  10. Change From Baseline to End-of-Treatment (EoT) in Pre-Dialysis Transferrin [Up to 48 weeks from date of randomization]

    The Mean Change from Stage 2 Baseline to End-of-Treatment (EoT) in Pre-Dialysis Transferrin

  11. Change From Baseline to End-of-Treatment (EoT) in Pre-Dialysis Transferrin Saturation (TSAT) [Up to 48 weeks from date of randomization]

    The Mean Change from Stage 2 Baseline to End-of-Treatment (EoT) in Pre-Dialysis Transferrin Saturation (TSAT)

  12. Variability of Hemoglobin Concentration: Temporal Trend [up to 48 weeks from date of randomization]

    The mean temporal trend of hemoglobin concentration value changes, as measured weekly from baseline until the end of participation in Stage 2.

  13. Variability of Hemoglobin Concentration: Residual Standard Deviation [up to 48 weeks from date of randomization]

    The mean residual standard deviation of the hemoglobin concentration changes, as measured weekly from baseline until the end of participation in Stage 2.

Adverse Events

Time Frame In Stage 2, subjects were randomized to placebo or SFP. They were in Stage 2 for up to 48 weeks. Upon completion of Stage 2, subjects could enter the open-label Stage 3 (all received SFP). The maximum total time on study (Stage 2 + Stage 3) was 72 weeks.
Adverse Event Reporting Description The number of subjects included in the safety population = 288, which is 6 subjects fewer than the number of subjects randomized. This discrepancy is due to the fact that the Safety population includes only those subjects exposed to study drug. Six subjects withdrew from Stage 2 prior to study drug exposure.
