NCT00796679

Brief Summary

The purpose of this study is to test the hypothesis that selective vitamin D receptor activation reduces left ventricular hypertrophy and ameliorates inflammation and atherosclerosis in stage 3 -5 chronic kidney disease.

Outcome Measures

Primary Outcomes (1)

  • Change in left ventricular mass index determined by MRI

    1 year

Secondary Outcomes (1)

  • Change in left atrial and ventricular volumes, systolic and diastolic function, carotid intima-media thickness, flow mediated dilation, pulse wave velocity, serum inflammatory and cardiac biomarkers, intact PTH, 24-hour urine protein and renal function

    1 year

Study Arms (2)

1

EXPERIMENTAL

paricalcitol

Drug: paricalcitol

2

PLACEBO COMPARATOR

placebo

Drug: paricalcitol

Interventions

oral paricalcitol capsule 1 microgram once daily if iPTH \<500pg/mL or 2 microgram once daily if iPTH \>=500pg/mL. Thereafter, dose titration in 1 microgram decrement will be done based on safety reasons (that is, for low PTH or high calcium and phosphorus level). The duration of treatment will be for 1 year.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient with stage 3 -5 chronic kidney disease (that is, eGFR \< 60 ml/min per 1.73m2) diagnosed for more than 2 months and not expected to start dialysis within the next 12 months, and
  • Patient with screening echocardiography showing evidence of left ventricular hypertrophy
  • Patient has not received vitamin D therapy in the previous 4 weeks
  • For entry into the Treatment Phase, the subject must have:
  • screening iPTH \>= 55 pg/ml or 5.8pmol/L (determined by the Nichols second-generation assay or similar assay)
  • serum calcium \< 10.2 mg/dL (2.55 mmol/L)
  • serum phosphorus =\< 5.2mg/dL (1.68mmol/L)
  • Ca\*P product \< 54 mg2/dL2 (4.36mmol2/L2)
  • If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or is of childbearing potential and practicing birth control measures.
  • Patients who provide informed consent for the study

You may not qualify if:

  • Patient with a history of an allergic reaction or significant sensitivity to vitamin D or vitamin D related compounds.
  • Patient with history of renal stones
  • Patient with current malignancy
  • Patients with clinically significant gastrointestinal disease or liver disease
  • Patient with acute renal failure in the recent three months
  • Patient with a history of drug or alcohol abuse within six months prior to the screening phase
  • Patient is known to be human immunodeficiency virus (HIV) positive.
  • Patient with evidence of poor compliance with diet and medication.
  • Patient currently receiving medications that may affect calcium, phosphorus metabolism such as calcitonin, cinacalcet, bisphophonates or vitamin D compounds (other than study drug), or other drugs that may affect calcium or bone metabolism, other than females on stable estrogen and/or progestin therapy.
  • Patients with active granulomatous disease
  • Patient with pregnancy
  • Patients currently receiving glucocorticoid steroid or other immunosuppressive treatment or had been administered glucocorticoid or other immunosuppressive treatment for more than 14 days within recent 6 months.
  • Patients with contraindication for MRI examination
