Brief Summary:
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 simultaneous 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 B will be followed for five-to-eight years, with the average length of follow-up being six and a half years.
Combination therapy will use angiotensin-converting-enzyme inhibitor (ACE-I) and an angiotensin-receptor blocker (ARB). Monotherapy will use ACE-I alone.
Combination therapy will use angiotensin-converting-enzyme inhibitor (ACE-I) and an angiotensin-receptor blocker (ARB). Monotherapy will use ACE-I alone.
Detailed Description:
\* 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 estimated Glomerular Filtration Rate (eGFR), end-state renal disease (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).
