Eksperimentell: Cinacalcet
|
Subjects randomized to treatment with cinacalcet will receive an initial oral dose of 30 mg once daily.
Doses will be titrated incrementally to 60, 90,120, and 180 mg per day based upon periodic measurements of serum calcium and plasma PTH levels.
Cinacalcet is formulated as light green tablets in 30, 60, and 90 mg free-based equivalents.
Tablets will be 30, 60, and 90 mg, graduated in size, smallest to largest.
Combinations of these 3 fixed dosage formulations will be used to achieve the 120 and 180 mg daily doses.

Aktiv komparator: Traditional Vitamin D Therapy
|
Traditional vitamin D therapy (eg, calcitriol, paricalcitol, alfacalcidol, doxercalciferol), to manage secondary hyperparathyroidism (SHPT) in this study will be administered according to strategies that have been used in clinical practice and that conform to current therapeutic recommendations and available clinical practice guidelines and product labeling.
