5. Study Description

Brief Summary
Study objective: To investigate the potential anti-proteinuric efficacy of aliskiren, a novel direct renin inhibitor (DRI), in addition to angiotensin receptor blocker (ARB) in immunoglobulin A nephropathy (IgAN) patients at risk of developing progressive renal failure.
Detailed Description
This will be an open-label pilot study in which IgAN patients with persistent proteinuria despite maximum dose of ARB treatment will be assigned to receive Aliskiren. There is the optional addition of other anti-hypertensive agents to achieve an optimal target blood pressure of <130/80 mmHg.
