CLICK Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: ChlorthalidoneExperimental Treatment1 Intervention
Subjects with stage 4 chronic kidney disease (CKD) and poorly controlled hypertension confirmed by 24 hour ambulatory blood pressure monitoring will be randomized into two groups, one receiving placebo and one receiving a diuretic called chlorthalidone (12.5 mg at randomization). Doubling of the dose of the diuretic (up to 50 mg) or placebo will occur every 4 weeks if required by home blood pressure (BP) results.
Group II: PlaceboPlacebo Group1 Intervention

Doubling of the dose of the diuretic (up to 50 mg) or placebo will occur every 4 weeks if required by home BP results.
