Design outcomes

Primary

MeasureTime frame
Primary endpoint: To compare the efficacy of suvorexant versus placebo on the reduction of sleep systolic blood pressure (SBP) by ambulatory blood pressure monitoring (ABPM).

Secondary

MeasureTime frame
Secondary endpoints: 1. To compare the percent change from non-dippers to dippers. 2. To compare the efficacy of suvorexant versus placebo on the reduction of morning SBP by ABPM and HBPM. 3. To compare the efficacy of suvorexant versus placebo on the reduction of morning SBP variability by ABPM and HBPM. 4. Changes in the total sleep time (TST) (self-reported). 5. Changes in the time to sleep onset (TSO) (self-reported). 6. To study the correlation of changes of sleep BP parameters with changes of sleep quality parameters 7. To study the correlation of changes of urinary albumin-to-creatinine ratio (UACR) / NT-proBNP.
