Design outcomes

Primary

MeasureTime frame
1. Efficacy Percent change of calcium absorption from baseline in the ELD group. 2. Safety Summarizing and aggregation of number and frequency of all adverse events occurring. The point of assessment for efficacy and safety is 28 days after starting administration.

Secondary

MeasureTime frame
Efficacy 1) Secondary outcomes 1. Percent change of calcium absorption from baseline in groups without ELD group. 2. Comparison the percent change of calcium absorption from baseline between groups. 3. Comparison the ratio of calcium absorption from baseline between groups. 4. Comparison the ratio of calcium absorption at final dosing between groups. 2) Other outcomes 1. Percent change of uNTX from baseline in groups 2. Comparison the percent change of uNTX from baseline between groups. 3. Change of calcium and phosphorus regulation-hormones (25(OH)D, 1,25(OH)2D, intact-PTH, FGF23) from baseline in the group. 4. Comparison calcium and phosphorus regulation-hormones at the pre-dosing and post-dosing between groups. 5. Relationship between subjects' background of screening or pre-dosing examination or calcium related test items and calcium absorption ratio from intestine. 6. Relationship between subjects' background of screening or pre-dosing examination or calcium related test items and percent change of calcium absorption ratio from intestine. 7. Relationship between calcium related test items or calcium and phosphorus regulation-hormones and change in intestinal calcium absorption ratio between pre-dosing and post-dosing in each group.
