Arms Assigned Interventions
Experimental: Aliskiren Drug: Aliskiren
Titrate from 150 mg daily to 300 mg daily
Other Name: Rasilez

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.
