Brief Summary

Diabetic kidney disease (nephropathy) develops in nearly 40% of patients with type 2 diabetes mellitus. Diabetic nephropathy is caused by damage to the small blood vessels in the kidneys due to uncontrolled blood sugar levels, which mean that the kidneys become less effective at filtering urine. This is associated with albuminuria (protein in the urine). Treatment with some drugs reduces the loss of albumin through the urine and delays disease progression. There is increasing evidence that vitamin D could also be important in management of diabetic kidney disease. The aim of this study is to investigate the efficacy and safety of a combined regimen of calcitriol (active vitamin D) and established drugs for diabetic kidney disease.

    26 weeks

  • Estimated glomerular filtration rate (eGFR)

    26 weeks

    26 weeks

Other Outcomes (1)

  • Patient Reported Outcome: Quality of life

    26 weeks

Study Arms (2)

Intervention Group

EXPERIMENTAL

Participants are treated with angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) AND active vitamin D (Calcitriol) 0.25 micrograms orally per day for 26 weeks.

Drug: Calcitriol

Usual Care

NO INTERVENTION

Participants are treated with ACEI/ARB alone for 26 weeks.

Interventions

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age greater than or equal to 18 years and less than 80 years
  • Diagnosis of T2DM requiring treatment with at least one oral hypoglycaemic medication or insulin 2.1. Subjects will be considered to have established T2DM if the diagnosis of diabetes has been made and the subjects were treated with insulin or an oral hypoglycaemic agent for at least 6 months after diagnosis 2.2. Subjects will be considered to have newly established T2DM if the diagnosis of diabetes was diagnosed with a fasting plasma glucose ≥ 7 mmol/L (126 mg/dL) or haemoglobin A1c is \>6.5% in the past 6 months
  • Documented albuminuria defined as a presence of albuminuria on two occasions in the last six months:
  • Albumin ≥ 30 mg/24 hour in a 24 hour urine collection, or 3.2. Albumin ≥ 20 μg/min in a short-time urine collection, or 3.3. Albumin ≥ 30 mg/L in a spot urine sample, or 3.4. A spot-urine albumin-creatinine ration (ACR) ≥ 30 mg/g creatinine (≥ 2.5 mg/mmol creatinine in men, ≥ 3.5 mg/mmol creatinine in women)
  • Estimated glomerular filtration rate (eGFR) using the 4-variable Modification of Diet in Renal Disease (MDRD) equation of ≥ 25 mL/min/1.73 m2

You may not qualify if:

  • If female, positive pregnancy test or planning pregnancy in the subsequent 12 months
  • Pregnant
  • Breastfeeding
  • Corrected serum calcium ≥ 2.62 mmol/L
  • Serum Potassium \> 5.2 mmol/L if not on ACEI or ARB; Serum Potassium \> 6.0 mmol/L if on ACEI or ARB
  • hydroxyvitamin D (25-OH Vit D) \> 80 ng/mL
  • PTH \> 200 pg/mL
  • Poorly controlled hypertension defined as systolic blood pressure ≥ 180 mm Hg or diastolic blood pressure ≥ 110 mm Hg
  • Systolic blood pressure (SBP) ≤ 110 mm Hg
  • History of kidney stones
  • History of severe chronic disease (e.g. chronic liver disease)
  • Active malignancy
  • Recent diagnosis of acute renal failure within 3 months of screening visit
  • Likelihood of renal replacement therapy within 1 year
