Primary outcomePrimary: Percent Change From Baseline in Mean Pre-hemodialysis Parathyroid Hormone (PTH) During the Efficacy Assessment Phase — 0.3; -19.4; 28.5; -49.4 percent change — p=<0.0001
Summary
The purpose of this study is to characterize the safety and tolerability and efficacy of multiple ascending doses of etelcalcetide in hemodialysis patients for the treatment of secondary hyperparathyroidism (HPT).
