Reporting Groups
  Description
Cinacalcet Cinacalcet administered orally in doses of 30, 60, 90, 120 or 180 mg per day. Participants could be titrated up to maximum dose based on PTH (parathyroid hormone), serum calcium and safety assessments.
Placebo Participants were given matching placebo tablets compared to the cinacalcet group.
