ESKD participants with history of secondary hyperparathyroidism (SHPT) undergoing maintenance hemodialysis

Brief summary

The proportion of participants with a ≥30% decrease in mean iPTH during the Efficacy Assessment Period (EAP, Weeks 22 - 27) relative to the mean baseline iPTH (all Active Screening and predose Day 1 iPTH values)., Open-Label Phase • Safety clinical laboratory tests, vital signs, ECG, AEs, and physical exams ", Open-Label Phase • Proportion of participants with a cCa <7.5 mg/dL, and the proportion of participants with a cCa <8.3 mg/dL

Detailed description
