Trial Outcomes & Findings for Evaluation of the Conversion From Peginesatide to Epoetin Alfa in Patients Receiving Hemodialysis (NCT NCT01737879)

NCT ID: NCT01737879

Last Updated: 2014-04-21

Results Overview

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.

PRIMARY outcome

Timeframe: 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.

Outcome measures

SECONDARY outcome

Timeframe: 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.
