Paricalcitol and Endothelial Function in Chronic Kidney Disease Patients (the PENNY Study)
Chronic Kidney Disease.The primary aim of this study was to test the hypothesis that Paricalcitol, an active form of vitamin D, improved endothelial function in stage 3-4 chronic kidney disease (CKD) patients. A secondary aim of this trial was to study the relationship between endothelial function and plasma/serum and genetic biomarkers of bone mineral disorders in CKD (BMD-CKD) and renin angiotensin-aldosteron system (RAS) (angiotensin II and plasma renin activity).
Efficacy of Vitamin D2 to Treat Chronic Kidney Disease Mineral and Bone Disorder
Vitamin D DeficiencyIt 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.
Effect of An Oral Absorbent AST-120 in Late-stage Chronic Kidney Disease (CKD) Patients.
Chronic Kidney DiseaseAST-120Recent research work has directed especial attention toward a distinct group of uremic retension molecules, called "protein-bound uremic toxins". The prototypes of this group of uremic toxins are indoxyl sulfate and p-cresol. These uremic toxins can promote production of free radical and impair antioxidant system and exerts direct toxicity on different cells and organs, including mesangial, tubular, endothelial cell and osteoblasts. Accumulation of these protein bound uremic toxins results in glomerular sclerosis and interstitial fibrosis of kidneys of uremic rats and confer skeletal resistance to parthyroid hormone in uremic patients. In hemodialysis, high serum p-cresol level is associated with higher cardiovascular mortality. AST-120 (Kremezin) is a carbonated oral absorbent extensively used in Japan and Korea. It has superior adsorption ability for certain small-molecular weight organic compounds known to accumulate in patients with CKD. In uremic rats and CKD patients, oral administration of AST-120 decreased the elevated pretreatment levels of serum indoxyl sulfate. In Japan, it was reported that AST-120 suppressed the increase in serum creatinine levels, prevented proteinuria, improved uremic symptoms, and, consequently, led to the postponement of dialysis therapy. Value of AST-120 on the outcome of late-stage CKD patients is still unknown. We hypothesized AST-120 through reduction of level of indoxyl sulfate and p-cresol can improved the morbidity- mortality of CKD patients. The principal aim of this prospective cohort study is to investigate the effectiveness of AST-120 in incidence of dialysis and mortality of late-stage CKD patients. Determination of this relationship can help to establish new therapeutic strategy in the treatment of late-stage CKD patients.

Paricalcitol Effect on Anemia in CKD
AnemiaChronic Kidney DiseaseCurrent activated Vitamin D therapies are approved for treating secondary hyperparathyroidism in chronic kidney disease (CKD), and a large body of experimental data in animals confirms the effects of Vitamin D that extend beyond mineral metabolism. Several studies show that the benefits are greater with the newer vitamin D analog paricalcitol when compared with calcitriol. A large gap exists in our knowledge between epidemiological studies in human that demonstrate improved outcomes with vitamin D use and observations in preclinical studies demonstrating the pleiotropic effects of Vitamin D. To explore the provenance of epidemiological outcomes in CKD, we conducted a pilot randomized trial to determine whether the use of paricalcitol, compared to calcitriol, leads to improvement in anemia, a marker associated with worse outcomes in chronic kidney disease, and whether this effect not only reflects the hyperparathyroidism correction, but is also dependent on the direct effects of paricalcitol on erythroid progenitor cells.

4 Week Switch Study in Hemodialysis-dependent Subjects With Anemia Associated With Chronic Kidney...
AnaemiaThis is a four-week, Phase IIa, randomized, active-controlled, parallel-group, multi-center study to evaluate the safety, efficacy and pharmacokinetics of switching subjects from stable rhEPO to GSK1278863 in approximately 68 hemodialysis-dependent subjects with anemia associated with chronic kidney disease. The study consists of a screening phase of 2 weeks, a 4-week treatment phase and a 2-week follow-up phase. The range of Hgb values for study eligibility is 9.5-12.0 g/dL and the subjects must have received the same rhEPO product with total weekly doses that varied by no more than 50% during the 4 weeks prior to the Screening visit (Week -1. This study aims to estimate the relationship between dose of GSK1278863 and Hgb response in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease after switching from a stable maintenance dose of recombinant human erythropoetin (rhEPO).

Chronic Kidney DiseaseDiabetesThe purpose of this study is to ask whether treating non-diabetic chronic kidney disease (CKD) patients with GFR 8-20mL/min/1.73m2 by darbepoetin Alfa targeting Hb between 11.0 and 13.0g/dL preserves renal function better than targeting Hb between 9.0 and11.0g/dL. The investigators also ask whether the higher Hb targeting 11 to 13g/dL will not cause higher adverse events regarding cardiovascular diseases compared with lower Hb targeting 9 to 11g/dL.
