A Phase 3 interventional study of Cinacalcet and Placebo in Secondary Hyperparathyroidism and Chronic Kidney Disease, sponsored by Amgen. Completed. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-11-07.

The purpose of this study is to evaluate the effects of cinacalcet (cinacalcet HCl or Sensipar®/Mimpara®) on cardiovascular events and death in chronic kidney disease (CKD) patients with secondary hyperparathyroidism (HPT) who are receiving dialysis.
Secondary HPT is common in people with CKD. Patients with secondary HPT often have high parathyroid hormone (PTH) levels and may develop large parathyroid glands in the neck. Patients with secondary HPT may have bone disease (osteodystrophy). This bone disease may cause bone pain, fractures, and poor formation of red blood cells. Other problems from secondary HPT may include increases in blood levels of calcium and phosphorus. These may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), or heart and lung problems. New evidence suggests that secondary HPT is associated with cardiovascular disease and increased death risk. The purpose of this study is to evaluate the effects of cinacalcet (cinacalcet HCl or Sensipar®/Mimpara®) on cardiovascular events (having to do with the heart and its blood vessels) and death in chronic kidney disease (CKD) patients with secondary hyperparathyroidism (HPT) who are receiving dialysis. These events include death from any reason, heart attack and episodes where the heart does not get enough oxygen, peripheral vascular disease (narrowing of vessels that carry blood to the legs, arms, stomach or kidneys), and heart failure (a condition that occurs when the heart is unable to pump enough blood to meet the need's of the body's tissues)

Inclusion Criteria:
Exclusion Criteria: - Exclusion:
Anticipated parathyroidectomy within 6 months after randomization
Drug: Cinacalcet
Drug: Placebo
Possible doses: 30, 60, 90, 120, and 180 mg using tablet strengths of 30, 60, or 90 mg. Sequential titration starting at 30 mg daily (QD), once every 4 weeks for the first 20 weeks and once every 8 weeks after Week 20. Titration increases or decreases based on PTH values, serum calcium, and safety. Daily dosing unless temporary hold criteria or withdrawal criteria is met, or until study completion; estimated 2.5 to 4 years of intervention.
