Time frame · Baseline (Day -1) and Days 20 and 48.

Twenty four-hour BP was determined using an ABPM device, and the mean change from baseline in the 24-hour systolic BP and 24-hour diastolic BP are presented for Days 20 and 48.

Mean Percentage Change From Baseline in Glucose Area Under the Plasma Concentration Curve (AUC[0-4h]) as Measured by a Standardised Mixed-Meal Test (MMT) at Day 48

Time frame · Baseline (Day -1) and Day 48: 15 minutes before standardised meal, and then at 15, 30, 45, 60, 90, 120, 180 and 240 minutes (+/-5 minutes) after consumption of the standardised meal.

The MMT was conducted following a minimum 8-hour fast. Blood samples for glucose monitoring were taken 15 minutes before the patient consumed a standardised meal, and samples were taken at intervals after the meal, up to 4 hours. The MMT glucose AUC(0-4h) was calculated using a trapezoidal method, and the mean percentage change from baseline at Day 48 was analysed using an analysis of covariance (ANCOVA) model with treatment group as a factor and baseline as a covariate.

Mean Change From Baseline in Fasting Plasma Glucose at Day 48

Time frame · Baseline (Day -1) and Day 48 (predose).

The mean change from baseline in fasting plasma glucose at Day 48 was analysed using an ANCOVA model with treatment group as a factor and baseline as a covariate. For patients who prematurely discontinued IP, or for patients who did not have a measurement taken on Day 48, the last post-baseline measurement, regardless of rescue medication, was used (LOCF).

Mean Change From Baseline in Fructosamine at Day 48

Time frame · Baseline (Day -1) and Day 48 (predose).

The mean change from baseline in fructosamine at Day 48 was analysed using an ANCOVA model with treatment group as a factor and baseline as a covariate. For patients who prematurely discontinued IP, the last on-treatment measurement, regardless of rescue medication, was used (LOCF).

Mean Change From Baseline in the Percentage of Time in Hyperglycaemia Over 24 Hours at Days 5, 12, 19 and 47

Time frame · Baseline (Day -8 to -2) and Days 5, 12, 19 and 47.

Hyperglycaemia was defined as blood glucose \>7.8 mmol/L or \>140 mg/dL. Continuous glucose monitoring used a device fitted to the upper arm by trained study site staff to measure and record interstitial glucose levels every 15 minutes. Analysis was based on 24-hour readings defined as the first available time point with a valid continuous glucose monitoring glucose reading. The change in the percentage time in hyperglycaemia from the last day of baseline continuous glucose monitoring over 24 hours to the end of dosing at each dose level for the indicated timepoints is presented.

Hypoglycaemia was defined as blood glucose \<3 mmol/L or \<54 mg/dL. Continuous glucose monitoring used a device fitted to the upper arm by trained study site staff to measure and record interstitial glucose levels every 15 minutes.
