简要总结
The primary objective of this study was to establish the bioequivalence of two different tablet formulations containing BAY77-1931. The secondary objectives of this study were to assess the safety and tolerability, as well as to Investigate the plasma lanthanum concentration after BAY 77-1931 ODT 500 mg administration.

结局指标
主要结局
Pharmacodynamics: Daily urinary phosphate excretion (mmol) on each day
时间窗: 6 days
Each study drug was administered as multiple dose over 4-days under fed conditions with a washout interval of at least 14 days in between. Twenty four hours urine collection were repeated 5 times from morning on Day -2 to that on Day 4.
Bioequivalence: Average of daily urinary phosphate excretion (mmol) over 3-day dosing period
时间窗: baseline and over 3-days
During lanthanum carbonate TID treatment period over 3 days in each period (period 1 = day 1-3; period 2 = day 4-6)
次要结局
- Pharmacodynamics: Daily urinary phosphate excretion (mmol) on Day 3(1 day)
- Pharmacokinetics: tmax,md of lanthanum in plasma from pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
- Number of adverse events as a measure of safety and tolarability(From Day 1, the day of the first study drug administration, in period 1 (day 1-3) to follow up, 7-10 days after the last study drug administration in period 2 (day 4 - 6))
- Pharmacokinetics: AUC(0-tlast)md of lanthanum in plasma from pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
- Pharmacokinetics: t1/2,md of lanthanum in plasmafrom pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
- Plasma lanthanum concentrations (ng/mL)(6 days)
- Pharmacokinetics: Cmax,md of lanthanum in plasma from pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
- Pharmacokinetics: Cmax,md,norm of lanthanum in plasma from pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
- Pharmacokinetics: AUC(0-tlast)md,norm of lanthanum in plasma from pre-administration (Day 4) to 48 hours after the last administration (Day 6)(6 days)
