Study Endpoints

Primary Endpoints

Change in serum phosphate concentrations in the AP301 and the AP301 low dose groups
From Baseline to the end of Week 8

The amount of phosphate in the blood will be measured with a standard laboratory test. The change in phosphate levels will be compared between the group receiving AP301 and the group receiving AP301 low dose.

Secondary Endpoints

Chang in serum phosphate concentrations in the AP301 maintenance dose and the AP301 low dose groups
From the beginning of Week 33 to the end of Week 35
Change in serum phosphate concentrations over time throughout the study
From Baseline to the end of Week 35
Change in serum calcium (Ca) and intact parathyroid hormone levels over time
From Baseline to the end of Week 35
