Condition(s) targeted: Vitamin D Deficiency

Intervention: Vitamin D2 (Drug); 1,25(OH)2 Vitamin D3 (Drug)

Phase: Phase 4

Status: Enrolling by invitation

Summary

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.

Clinical Details

Official title: Study of Vitamin D2 Virus 1,25(OH)2-Vitamin D3 in the Treatment of Chronic Kidney Disease Mineral and Bone Disease

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: The changes on the blood levels of calcium, phosphorus, and intact parathyroid (iPTH) hormone during 24 months.

Secondary outcome:

The changes of the blood 25(OH)Vitamin D level.

The incidence rate of secondary hyperparathyroidism.

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.
