About this study

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

It is hypothesised that the efficacy and safety of Vitamin D2 soft capsule to treat the Chronic Kidney Disease Mineral and Bone Disease (CKD-MBD) are equal to 1,25(OH)2 Vitamin D3 (Rocaltrol) in the patients with CKD stage 3-5.

Read the 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 Vitamin D2 soft capsule or Rocaltrol. A total of 200 patients will be enrolled, 100 in the Vitamin D2 group and 100 in the 1,25(OH)2 Vitamin D3 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.

Study groupRoleWhat they receive
Vitamin D2 TreatmentExperimentalPatients will be treated by 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.
Receives: Drug: Vitamin D2
1,25(OH)2 Vitamin D3Active comparatorPatients will be treated by 1,25(OH)2 Vitamin D3. Oral 1,25(OH)2 Vitamin D3(Rocaltrol) 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.
Receives: Drug: 1,25(OH)2 Vit D3

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Blood Levels of Calcium at the 24th Month of Following up.

    The blood levels of calcium at the 24th month of following up will be detected.

    Measured: 24 months

  2. The Blood Levels of Phosphorus at the 24th Month of Following up.

    The blood levels of phosphorus at the 24th month of following up will be detected.

    Measured: 24 months

  3. The Blood Levels of Intact Parathyroid Hormone at the 24th Month of Following up.

    The blood levels of intact parathyroid hormone (iPTH) at the 24th month of following up will be detected.

    Measured: 24 months

Secondary outcomes (2)
  1. The Blood 25(OH)Vitamin D Level.

    The levels of blood 25(OH)Vitamin D at the 24th month of following up.

    Measured: 24 months

  2. The Incidence Rate of Secondary Hyperparathyroidism.

    Patients with the blood iPTH level higher than 300 pg/ml will be regard as sHPT. The incidence of sHPT during following up were recorded and compared between two groups.

    Measured: 24 months
