Eligibility Criteria
Inclusion Criteria: Diagnosis of ADPKD. Age 15-49 (Study A); Age 18-64 (Study B). GFR >60 mL/min/1.73 m2 (Study A); GFR 25-60 mL/min/1.73 m2 (Study B). BP ≥130/80 or receiving treatment for hypertension. Informed Consent. Exclusion Criteria: Pregnant/intention to become pregnant in 4-6 yrs. Documented renal vascular disease. Spot urine albumin-to-creatinine ratio of >0.5 (Study A) or ≥1.0 (Study B) and/or findings suggestive of kidney disease other than ADPKD. Diabetes requiring insulin or oral hypoglycemic agents / fasting serum glucose of >126 mg/dl / random non-fasting glucose of >200 mg/dl.

History of angioneurotic edema or other absolute contraindication for ACE-I or ARB. Intolerable cough associated with ACE-I is defined as a cough developing within six months of initiation of ACE-I in the absence of other causes and resolving upon discontinuation of the ACE-I. Indication (other than hypertension) for β-blocker or calcium channel blocker therapy (e.g. angina, past myocardial infarction, arrhythmia), unless approved by the site principal investigator. (PI may choose to accept an individual who is on only a small dose of one of these agents and would otherwise be eligible.)
