Participant Flow

Men and women at least 18 years of age, receiving hemodialysis (HD) for at least 3 months, with serum P concentrations \> 5.5 mg/dL at the end of the washout period, and on a stable dose of P binder and/or active vitamin D (if previously prescribed) for at least 1 month prior to the study were eligible for study participation.

Patients were excluded if they did not previously respond to P binder therapy, had a known non-compliance with oral medications, severe hyperparathyroidism defined as intact-PTH (i-PTH) \> 500 pg/ml, were taking any calcium-, magnesium- or aluminum-containing antacids or used an investigational agent within 30 days of study entry.
