Study Stopped
International shortage of the chemical para-aminohippuric acid (PAH) due to manufacturing changes, led to inability to perform key measurements to meet trial objectives

Brief Summary
In a 6 week pilot study, 20 individuals with habitual sleep restriction will all be asked to extend their nightly sleep by 1 hour, and will then be randomized 1:1 to nightly controlled-release oral melatonin (2mg) or placebo. The investigators will assess whether sleep extension and nightly melatonin supplementation in the community is a feasible intervention with a beneficial effect on the following chronic kidney disease (CKD) risk factors: systemic and renal specific renin-aldosterone-angiotensin system (RAAS) activation (systemic plasma renin activity, plasma angiotensin II levels, 24-hour urine aldosterone excretion, and renal plasma flow response to captopril); nocturnal blood pressure measured by 24-hour ambulatory blood pressure monitor; central blood pressure measured by pulse wave analysis; and glucose metabolism measured by Minimal Model assessment of insulin resistance and β-cell response to a mixed meal protocol.

Outcome Measures
Primary Outcomes (2)
Change in Renal Specific Renin-aldosterone-angiotensin System (RAAS) Activity
renal specific RAAS activity will be assessed via para-aminohippurate (PAH) renal plasma flow testing with captopril

Change in Systemic Renin-aldosterone-angiotensin System (RAAS) Activity
systemic RAAS will be assessed by plasma renin activity (PRA), angiotensin II (Ang II) levels and urine aldosterone
6 weeks
Secondary Outcomes (2)
Change in Glucose Metabolism
6 weeks
Change in Central Blood Pressure
6 weeks
Study Arms (2)
Melatonin
EXPERIMENTALCircadin, controlled release melatonin tablet 2mg by mouth each day before bedtime for 6 weeks
Placebo
PLACEBO COMPARATORPlacebo tablet identical to Circadin by mouth each day before bedtime for 6 weeks
