Results

After 18 months, HbA1c had significantly decreased to 7.1-7.2% in both groups (P < 0.01). Plasma levels of insulin and proinsulin remained unchanged during the study. However, the proinsulin/insulin ratio was significantly lower after 6 months and thereafter only in the SU group. Homeostasis model assessment-be-ta cell (HOMA-be-ta) demonstrated a significant augmentation at some points during the study in both groups. No severe hypoglycemic episodes or body weight gain were seen in either group.

Baseline Characteristics

Japanese patients with type 2 diabetes mellitus

Participant flow

a daily administration of 50 mg sitagliptin added to a very small dose of glimepiride, SUs, of 1.1 mg (SIT group), versus a small dose of glimepiride added by 1 mg to its basal dosage, i.e., 2.1 mg (SU group)

Adverse events

Throughout the study, body weight did not show any increases in either group (Table 2). No severe hypoglycemic episodes were seen in either group except one each in the SIT and
SU group who discontinued the study as mentioned above.

Outcome measures

glycemic control and be-ta-cell function
