Aliskiren Combined With Losartan in Proteinuric, Non-diabetic Chronic Kidney Disease

2014-08-27 03:12:42 | BioPortfolio


Study objective: To investigate the potential anti-proteinuric and renoprotective efficacy of aliskiren in addition to losartan in patients at risk of developing end-stage renal disease (ESRD)

Methods: This will be a randomized, double-blind study in which proteinuric, non-diabetic patients with chronic kidney disease (CKD) will be assigned in a 1:1 ratio to one of the following treatment groups for 3 years:

- Group A: Losartan (Control arm: conventional treatment)*

- Group B: Aliskiren plus Losartan (Intervention arm)*

- With optional addition of other anti-hypertensive agents to achieve an optimal target blood pressure of <130/80 mmHg.


Aliskiren is a direct renin inhibitor that has been shown to reduce proteinuria and retard renal deterioration in type 2 diabetic patients with overt nephropathy. However, it is not known if these therapeutic effects can be extended to nondiabetic chronic renal disease. The current study aims to explore this research question by randomly assigning patients with various stages of chronic renal disease to receive either aliskiren on top of losartan, or continuation of losartan.

Medical and Biotech [MESH] Definitions

Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)

The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.

An autoimmune disease of the KIDNEY and the LUNG. It is characterized by the presence of circulating autoantibodies targeting the epitopes in the non-collagenous domains of COLLAGEN TYPE IV in the basement membranes of kidney glomeruli (KIDNEY GLOMERULUS) and lung alveoli (PULMONARY ALVEOLI), and the subsequent destruction of these basement membranes. Clinical features include pulmonary alveolar hemorrhage and glomerulonephritis.

KIDNEY injuries associated with diabetes mellitus and affecting KIDNEY GLOMERULUS; ARTERIOLES; KIDNEY TUBULES; and the interstitium. Clinical signs include persistent PROTEINURIA, from microalbuminuria progressing to ALBUMINURIA of greater than 300 mg/24 h, leading to reduced GLOMERULAR FILTRATION RATE and END-STAGE RENAL DISEASE.
