Primary outcomePrimary: Change From Baseline in Serum-phosphate Levels at the End of Treatment. — -0.042; -0.348; -0.404; -0.644 mmol/L
Summary
The purpose of this study is to investigate the ability of different doses of PA21 to lower serum phosphate levels, in patients with chronic kidney disease on maintenance hemodialysis.
