  Purpose

It is hypothesised that the efficacy and safety of ergocalciferol to treat the Chronic Kidney Disease Mineral and Bone Disease (CKD-MBD) are equal to calcitriol in the patients with CKD stage 3-5.

Primary Outcome Measures:
  • The changes on the blood levels of calcium, phosphorus, and intact parathyroid (iPTH) hormone during 24 months. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    The blood levels of calcium, phosphorus,and intact parathyroid (iPTH) will be detected every three months. The values during follow-up will be compared to the baseline.


Secondary Outcome Measures:
  • The changes of the blood 25(OH)Vitamin D level. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • The incidence rate of secondary hyperparathyroidism. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    Patients with the blood iPTH level higher than 300 pg/ml will be regard as sHPT.


Estimated Enrollment: 200
Study Start Date: July 2012
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vitamin D2 Treatment Drug: Vitamin D2
Oral Vit D2 1.25mg(50,000 unit) once weekly as a start and maintain 1.25mg(50,000 unit) once monthly according to the blood 25(OH)vitamin D level.
Other Name: Vit D2
Active Comparator: 1,25(OH)2 Vitamin D3 Drug: 1,25(OH)2 Vitamin D3
Oral 1,25(OH)2 Vitamin D3 by 0.25 microgram once daily at start and regulate the dose according to the changes of blood levels of 25(OH)Vit D, calcium, phosphorus, and intact parathyroid hormone.
Other Name: Active Vit D3

Detailed Description:

This study will enroll chronic kidney disease patients, stage 3 to 5, who have chronic kidney disease mineral and bone disease (CKD-MBD)as defined by Kidney Disease Improvement Global Outcome (KDIGO) Guidelines. Patients in one center will be randomized to receive oral ergocalciferol or calcitriol. A total of 200 patients will be enrolled, 100 in the ergocalciferol group and 100 in the calcitriol group. Outcomes will be assessed as proportion of patients achieving target blood levels on calcium, phosphorus, parathyroid hormone, and 25 hydroxyvitamin D. Other outcomes will also be assessed, which include secondary hyperparathyroidism (sHPT), vascular calcification, and cardiovascular diseases.
