It was calculated as insulin/glucose ratio was calculated as insulin AUC(0-3]/glucose AUC(0-3) during OGTT, while glucose/insulin ratio was calculated as glucose AUC(0-3)/insulin AUC(0-3) during OGTT. The point estimates and corresponding 95% CI for treatment ratios were calculated for treatment comparisons versus placebo.

  30. Part A: Summary of the OGTT Derived Parameters: Insulin Glucose Index [ Time Frame: Up to Day 1 (24 hours) ]
    Blood samples for the determination of glucose and other PD markers were collected at pre-dose on Day 1 of each dosing period and immediately prior to and at 10, 20, 30, 60, 90, 120, 180 min after administration of the 75 grams glucose drink. When this results in multiple samples at the same time point, only one sample was collected. It was calculated as insulin (30 min) - insulin (0 min)/glucose (30 min) - glucose (0 min). It was calculated as insulin (30 min) - insulin (0 min)/glucose (30 min) - glucose (0 min). The point estimates and corresponding 95% CI for treatment ratios were calculated for treatment comparisons versus placebo.

  31. Part A: Summary of the OGTT Derived Parameters: Insulin Sensitivity Index [ Time Frame: Up to Day 1 (24 hours) ]
    Blood samples for the determination of glucose and other PD markers were collected at pre-dose on Day 1 of each dosing period and immediately prior to and at 10, 20, 30, 60, 90, 120, 180 min after administration of the 75 grams glucose drink. When this results in multiple samples at the same time point, only one sample was collected. It was calculated as 10,000/square root ([mean plasma insulin × mean plasma glucose during OGTT or meal challenge] × [fasting plasma glucose × fasting plasma insulin]). The point estimates and corresponding 95% CI for treatment ratios were calculated for treatment comparisons versus placebo.

  32. Part C: Summary of Change From Baseline in Fasted Glucose [ Time Frame: Baseline (Day 1 pre-dose) and Day -1, 13 and 14. ]

For lunch (4 hour post-morning dose) samples were collected just before the meal and after starting each meal: 0.5, 1, 1.5, 2 and 3 hours. For the evening meal (10 hour post-morning dose), BID dosing groups followed the sequence of sampling, food and dosing as for breakfast (PD sample immediately before meal, eat and then dose), then 0.5, 1, 1.5, 2 and 3 hours post-dinner. A sample was also collected 24 hours post-dose. When this results in multiple samples at the same time point, only one sample was collected. Change from Baseline was calculated by subtracting Baseline value minus post-Baseline value. The point estimates and corresponding 95% CI for treatment ratios were calculated for treatment comparisons versus placebo.

For lunch (4 hour post-morning dose) samples were collected just before the meal and after starting each meal: 0.5, 1, 1.5, 2 and 3 hours. For the evening meal (10 hour post-morning dose), BID dosing groups followed the sequence of sampling, food and dosing as for breakfast (PD sample immediately before meal, eat and then dose), then 0.5, 1, 1.5, 2 and 3 hours post-dinner. A sample was also collected 24 hours post-dose. When this results in multiple samples at the same time point, only one sample was collected. Change from Baseline was calculated by subtracting Baseline value minus post-Baseline value. The point estimates and corresponding 95% CI for treatment ratios were calculated for treatment comparisons versus placebo.
