Trial Summary

What is the purpose of this trial?The purpose of this study is to demonstrate that treatment with etelcalcetide (AMG 416) is not inferior to treatment with cinacalcet for lowering serum parathyroid hormone (PTH) levels by \> 30% from baseline among patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT) who require management with hemodialysis.

Active Control

Group I: EtelcalcetideExperimental Treatment2 Interventions

Participants were randomized to receive etelcalcetide administered by intravenous bolus injection at the end of each hemodialysis session TIW, and daily oral doses of placebo tablets for 26 weeks. The starting dose of etelcalcetide was 5 mg, and could have been titrated at weeks 5, 9, 13, and 17 to target predialysis serum PTH ≤ 300 pg/mL but no lower than 100 pg/mL while maintaining cCa ≥ 8.3 mg/dL.

Group II: CinacalcetActive Control2 Interventions

Participants were randomized to receive oral cinacalcet once daily and placebo intravenous bolus injection at the end of each hemodialysis session, three times per week (TIW) for 26 weeks. The starting dose of cinacalcet was 30 mg daily and could have been titrated at weeks 5, 9, 13, and 17 to target predialysis serum PTH ≤ 300 pg/mL but no lower than 100 pg/mL while maintaining corrected calcium (cCa) ≥ 8.3 mg/dL.
