Dose Ranging Study of Dialysate Containing Soluble Iron to Treat Subjects With End Stage Renal Disease (ESRD) Receiving Chronic Hemodialysis
Study Details
Study Description
Brief Summary
The purpose of this study is to determine whether Dialysate containing soluble iron (Soluble Ferric Pyrophosphate) is safe and effective in maintaining physiological iron levels during chronic hemodialysis.

---|---|---|
|
Phase 2 |
Detailed Description
The study was designed to evaluate the efficacy of SFP-containing dialysate solution in maintaining physiological iron levels during chronic hemodialysis, as measured by the primary endpoint of the percent of patients whose Hemoglobin (Hgb) decreased by at least 1.0 gram/ deciliter (g/dL) from baseline. The efficacy and safety findings are to be used to determine the optimal concentration of SFP needed to safely maintain iron levels, compensating for iron losses during chronic hemodialysis.

Outcome Measures
Primary Outcome Measures
- Percent of Subjects Whose Hemoglobin (Hgb) Decreases by a Total of 1.0 Grams/ Deciliter (g/dL) (or More) From Baseline on Each of Two Successive Measurements. [up to 26 weeks]
Efficacy of a Soluble Ferric Pyrophosphate (SFP)-containing dialysate solution in maintaining physiological iron levels during chronic HD, as measured by the percent of subjects whose hgb decreases by a total of 1.0 g/dL (or more) from baseline on each of two successive measurements. Hemoglobin was obtained weekly at the mid-week dialysis treatments and compared to baseline value (average of two hgb measurements obtained at the two consecutive baseline visits prior to randomization).
Secondary Outcome Measures
- Change From Baseline in Hemoglobin (Hgb) [two time points: baseline and final evaluation (last post baseline assessment, up to 26 weeks)]
- Time in Days for Hgb to Decrease by a Total of > = 1.0 g/dL From Baseline on Each of Two Successive Measurements in Each Treatment Group. [Up to 26 weeks]
Kaplan-Meier Estimate of Time to First Hgb Decrease by >= 1.0 g/dL
- Reticulocyte Hemoglobin (CHr) Values Every Four Weeks, and at the End of the Subject's Treatment. [Every 4 weeks]
Efficacy of SFP administration in dialysate solution as measured by Chr values every four weeks, and at the end of the Subject's Treatment (up to 26 weeks).
- Number of Subjects With Infection Episodes Requiring Antibiotic or Anti-fungal Therapy in Each Treatment Group. [At each dialysis session for up to 26 weeks]
- Number of Subjects With a Rise in Hemoglobin (Hgb) to 12.6 g/dL or More on Two Separate Occasions Measured One Week Apart. [two separate sessions measured one week apart.]
