Evaluation of the Conversion From Peginesatide to Epoetin Alfa in Patients Receiving Hemodialysis
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate whether hemodialysis patients on peginesatide can be converted to epoetin alfa by using a predefined conversion table while achieving a stable hemoglobin.

Phase 4 |
Detailed Description
This is a phase 4, multicenter, single-arm, open-label study designed to evaluate whether patients receiving hemodialysis and treated with peginesatide can be converted to epoetin alfa using a predefined conversion table while achieving stable hemoglobin. The study will be conducted in two phases. Hemodialysis patients treated with epoetin alfa 3 times a week (TIW) will first be converted to peginesatide administered every 4 weeks (Q4W). After 24 weeks, these participants will be converted back to epoetin alfa administered TIW for 32 weeks. The primary endpoint will be the mean hemoglobin during the last 8 weeks of the epoetin alfa period.

Outcome Measures
Primary Outcome Measures
- Mean Hemoglobin Concentration During the Evaluation Period [Last 8 weeks of epoetin alfa treatment period period (Weeks 49 to 56).]
The hemoglobin concentrations during the evaluation period after the conversion to epoetin alfa were to be averaged for each participant and then summarized over all participants. No participant reached the evaluation period, therefore, the primary efficacy endpoint could not be evaluated.
Secondary Outcome Measures
- Mean Dose of Epoetin Alfa During the Evaluation Period [Last 8 weeks of epoetin alfa treatment period period (Weeks 49 to 56).]
No participant reached the evaluation period, therefore, this endpoint could not be evaluated.
- Hemoglobin Concentration by Visit [Baseline and Weeks 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21]
- Peginesatide Dose by Visit [Baseline and Weeks 5, 9, 13, and 17]

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results aftercompletion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
