  Purpose

The efficacy of interruption of the renin-angiotensin-aldosterone system (RAAS) on the progression of cystic disease and on the decline in renal function in autosomal dominant kidney disease (ADPKD) will be assessed in two multicenter randomized clinical trials targeting different levels of kidney function: 1) early disease defined by GFR >60 mL/min/1.73 m2 (Study A); and 2) moderately advanced disease defined by GFR 25-60 mL/min/1.73 m2 (Study B). Participants will be recruited and enrolled, either to Study A or B, over the first three years. Participants enrolled in Study A will be followed for a total of four years, while those enrolled in Study B will be followed for four-to-six years, with the average length of follow-up being five years. The two concurrent randomized clinical trials differ by eligibility criteria, interventions and outcomes to be studied.

Detailed Description:

* Specific Aims of Study A

To study the efficacy of ACE-I/ARB combination therapy as compared to ACE-I monotherapy and usual vs. low blood pressure targets on the percent change in kidney volume in participants with preserved renal function (GFR >60 mL/min/1.73m2)and high-normal blood pressure or hypertension (>130/80 mm Hg).

* Hypotheses to be tested in Study A

In ADPKD individuals with hypertension or high-normal blood pressure and relatively preserved renal function (GFR >60 mL/min/1.73 m2), multi-level blockade of the RAAS using ACE-I/ARB combination therapy will delay progression of cystic disease as compared to ACE-I monotherapy, and a low blood pressure goal will delay progression as compared with standard control.

* Specific Aim of Study B

To study the effects of ACE-I/ARB combination therapy as compared to ACE-I monotherapy in the setting of standard blood pressure control (110-130/80 mm Hg) on the time to a 50% reduction of baseline eGFR, ESRD or death, in hypertensive individuals with moderate renal insufficiency (GFR 25-60 mL/min/1.73m2).

* Hypothesis to be tested in Study B

In hypertensive ADPKD individuals with moderate renal insufficiency (GFR 25-60 mL/min/1.73 m2), intensive blockade of the RAAS using combination ACE-I/ARB therapy will slow the decline in kidney function over ACE-I monotherapy, independent of standard blood pressure control (110-130/80 mm Hg).
