The purpose of this study is to demonstrate the safety and effectiveness of Hectorol® (doxercalciferol) capsules in treating patients with Stage 3 or Stage 4 chronic kidney disease (CKD) with secondary hyperparathyroidism who have vitamin D levels in the normal range. Previous studies with doxercalciferol were conducted in patients who had low levels of vitamin D.

Renal Failure
Chronic Renal Insufficiency
Drug: Hectorol (doxercalciferol capsules), 0.5mcg
Phase 4

Study Type: Interventional
