PRIMARY outcome

Timeframe: Baseline and 12 weeks of each treatment

Population: Includes all randomized patients who completed the study with no major protocol violations. Crossover study design allows for the comparison of the effect of two treatments on the same patients, each patient served as own control for between-treatment comparisons. The data from two periods were combined and analyzed.

Glycosylated hemoglobin reflects the average blood glucose level over the previous 12 weeks of treatment.

SECONDARY outcome

Timeframe: over 12 weeks of each treatment period

Population: Includes all randomized patients who had at least one dose. Crossover study design allows for the comparison of the effect of two treatments on the same patients, each patient served as own control for between-treatment comparisons. The data from two periods were combined and analyzed.

Hypoglycemia rate per patient per 30 days = (number of reported hypogylcemia events/number of days within the period) \* 30 days. Since this was a 2x2 cross-over design (2 treatments and 2 periods), then the hypogyclemia rate was calculated per patient for each of the 2 periods by treatment.
