A Prospective Open-Label, Non-randomised, Single-arm, Pilot Clinical Study Evaluating the Efficacy of Paricalcitol On Erythropoietin Consumption in Calcitriol-Resistant Patients
This study will be a prospective open label, non-randomised, single-arm, pilot clinical study evaluating the efficacy of paricalcitol on erythropoietin consumption in calcitriol resistant patients with stage 5 chronic kidney disease.
Moderate to Severe Secondary Hyperparathyroidism
Stage 5 Chronic Kidney Diseases
|Study Design:||Endpoint Classification: Efficacy Study

|Official Title:||A Prospective Open Label Pilot Clinical Study Evaluating the Efficacy of Paricalcitol on Erythropoietin Consumption in Calcitriol-resistant Patients|
- change in erythropoietin (EPO) consumption in patients [ Time Frame: 6 months ] [ Designated as safety issue: No ]EPO dosage required to keep serum haemoglobin levels between 11 to 12 g/dl will be recorded.The recordings and blood tests to assess the haemoglobin levels will be conducted monthly.
- change in the quality of life scores of patients with chronic kidney disease (CKD) [ Time Frame: 6 months ] [ Designated as safety issue: No ]The quality of life of patients will be evaluated by using the SF-36 Questionnaire.
- the changes in commonly assessed biochemical parameters for bone and mineral metabolism (intact parathyroid hormone [iPTH], Calcium [Ca], Phosphorus [P], Vitamin B12, Folic acid ,Alkaline Phosphatase [ALP]) during treatment with paricalcitol. [ Time Frame: 6 months ] [ Designated as safety issue: No ]Blood tests
- change in High-sensitivity C-Reactive Protein (hsCRP) and Fibroblast growth factor 23 (FGF-23) values [ Time Frame: 6 months ] [ Designated as safety issue: No ]Blood tests
- Safety: Adverse Events-The number of participants with adverse events will be reported as a measure of Safety. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]The investigators will monitor each subject for clinical and lab evidence of adverse events on a routine basis through out the study.

|Estimated Primary Completion Date:||March 2014 (Final data collection date for primary outcome measure)|
Paricalcitol will be administered by intravenous route, and will be initiated in patients with a intact parathyroid hormone (iPTH) level >500 pg/mL, and the starting dose will be calculated according to the following formula; paricalcitol (µg) for each dialysis session= intact parathyroid hormone (iPTH) (pg/mL)/120.
