Groups2

Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov code
Group 1Cinacalcet
Participants were randomized to receive oral cinacalcet once daily and placebo intravenous (IV) bolus injection at the end of each hemodialysis session three times per week (TIW) for 26 weeks. The starting dose of cinacalcet was 25 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 cCa ≥ 8.3 mg/dL.

Group 2Etelcalcetide
Participants were randomized to receive etelcalcetide administered by IV 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.
