Study Endpoints
Primary Endpoints
Area Under the Serum Concentration-time Curve (AUC 0-48) for Exogenous Calcitriol
pre-dose, 1, 2, 3, 4, 5, 6, 8, 10, 12, 18, 24, 36, and 48 hours post calcitriol dose

This shows the effect that lanthanum carbonate or sevelamer carbonate has on the pharmacokinetics of oral calcitriol. Exogenous calcitriol was the difference between total calcitriol value and the baseline exogenous calcitriol value at each sampling timepoint.

Secondary Endpoints
Maximum Plasma Concentration (Cmax) for Exogenous Calcitriol
pre-dose, 1, 2, 3, 4, 5, 6, 8, 10, 12, 18, 24, 36, and 48 hours post calcitriol dose
Time of Maximum Plasma Concentration (Tmax) for Exogenous Calcitriol
pre-dose, 1, 2, 3, 4, 5, 6, 8, 10, 12, 18, 24, 36, and 48 hours post calcitriol dose
