PRIMARY outcome

Timeframe: Baseline and Week 2

Population: One patient in the Placebo group who withdrew prior to any testing was excluded from the analysis.

The area under the glucose time curve, between 0 and 120 minutes of the OGTT, was calculated for each patient using the trapezoidal rule . Change = Week 2 - Baseline.

Placebo
n=12 Participants
2 weeks of oral administration of a placebo tablet 30min before bedtime
Change From Baseline in Area Under the Curve (AUC) Glucose at Week 2
-794.2 (mg/dL)*min
Interval -1446.4 to -142.0
482.7 (mg/dL)*min
Interval -422.2 to 1387.7

SECONDARY outcome

Timeframe: Baseline and Week 2

Population: One patient from each group was excluded from the analysis since they were missing SI data at both Baseline and Week 2.

SI is estimated from modeling of the insulin and glucose values during the intravenous glucose tolerance test (ivGTT). Change = Week 2 - Baseline.

-0.46 [mU/L]^-1·[min]^-1
Interval -1.07 to 0.15

SECONDARY outcome

Timeframe: Baseline and Week 2

Population: Patients were excluded from the analysis if they were missing blood pressure data at both Baseline and Week 2.

The average systolic blood pressure measured over a 24-hr period was calculated for each patient. Change = Week 2 - Baseline.

SECONDARY outcome

Timeframe: Baseline and Week 2

Population: Patients were excluded from the analysis if they were missing blood pressure data at both Baseline and Week 2.

The average diastolic blood pressure over a 24-hr period was calculated for each patient. Change = Week 2 - Baseline
