Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Adults greater than or equal to 18 years of age on hemodialysis for > 3 and less than or equal to 12 months prior to enrollment into the study
  • Mean of 2 PTH determinations during the screening period (drawn at least 2 days apart) > 300 pg/mL (31.8 pmol/L); or biPTH > 160 pg/mL (17.0 pmol/L)
  • Mean of 2 corrected serum calcium determinations drawn on the same day as the PTH determinations greater than or equal to 8.4 mg/dL (2.1 mmol/L)
  • Subject will be able to complete the study, to the best of his/her knowledge
  • Before any study-specific procedure, the appropriate written informed consent must be obtained

Exclusion Criteria:

  • Mean of 2 PTH determinations during the screening period (drawn at least 2 days apart) > 800 pg/mL (84.9 pmol/L); or biPTH > 430 pg/mL (45.6 pmol/L) AND receiving vitamin D on entering screening

  • Known sensitivity, intolerance, or other adverse response to cinacalcet which would prevent on-study treatment compliance
  • Have an unstable medical condition within 30 days before screening, or otherwise unstable in the judgment of the investigator
