Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percent Change From Baseline in Mean Pre-hemodialysis Parathyroid Hormone (PTH) During the Efficacy Assessment Phase
Periodo de tiempo: Baseline and the efficacy assessment phase (EAP; defined as the period between 3 days before and 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)
Baseline is defined as the average of pre-hemodialysis values obtained on day -2 and day 1. The efficacy assessment phase (defined as 3 days before and 3 days after the last dose of investigational product) value is the mean of all predialysis values obtained during that period.
