Brief Title  ICMJE Cholecalciferol Versus Doxercalciferol in the Treatment of Secondary Hyperparathyroidism in Chronic Kidney Disease
Official Title  ICMJE Comparison of Cholecalciferol Versus Doxercalciferol in the Treatment of Secondary Hyperparathyroidism in CKD
Brief Summary The majority of patients with moderate to severe chronic kidney disease (CKD) (stages 3 and 4) develop secondary hyperparathyroidism (2°HPT), but the optimal therapy to control hyperparathyroidism in this group is unknown. The National Kidney Foundation presented guidelines in 2003 recommending vitamin D supplementation for vitamin D insufficient patients and active vitamin D therapy in patients with sufficient levels. These guidelines are based on opinion since there are no significant trials to determine if vitamin D supplementation is effective in this population. The active vitamin D metabolites doxercalciferol, paricalcitol, and calcitriol have been shown to effectively suppress parathyroid hormone (PTH), but have not been compared with vitamin D supplementation with a calciferol (ergocalciferol or cholecalciferol). Beyond hyperparathyroidism, small studies suggest vitamin D replacement in vitamin D insufficient non-CKD subjects result in improved pain, feeling of well being, blood pressure and strength. In this proposed study we wish to directly compare the effectiveness of cholecalciferol versus doxercalciferol in suppressing elevated PTH levels in subjects with CKD not on dialysis who have vitamin D insufficiency in a three month study. Secondary endpoints will be change in blood pressure.
Detailed Description Patients with CKD stage 3 were randomly allocated (by blinded group allocation) to either cholecalciferol (4000 U per day for one month then 2000 IU daily thereafter) or doxercalciferol (2.5 mcg po daily. Assessments for blood endpoints (primary end point PTH; secondary calcium, phosphorus) were done monthly. Other assessments (blood pressure) were done at baseline and at 3 months.

Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Condition  ICMJE Renal Osteodystrophy
Intervention  ICMJE
  • Drug: doxercalciferol
    form of vitamin D that is already in active form.
    Other Name: Hectoral
  • Drug: Cholecalciferol
    from of vitamin D that requires cells in the body to make active
    Other Name: vitamin D3
Study Arms  ICMJE
  • Experimental: Doxercalciferol
    doxercalciferol 1 mcg capsule orally daily for 3 months. This is a form of vitamin D that does not require activation by enzymes in the liver and kidney.
    Intervention: Drug: doxercalciferol
  • Active Comparator: Cholecalciferol
    cholecalciferol 4000 IU capsule orally daily for one month, then 2000 IU capsule daily orally for 2 months. this form of vitamin D requires activation by cells of the body.
    Intervention: Drug: Cholecalciferol
