Abstract
AIMS
Investigate efficacy and tolerability of intensifying diabetes treatment with once- or twice-daily biphasic insulin aspart 30 (BIAsp 30) added to sitagliptin, and twice-daily BIAsp 30 without sitagliptin in patients with type 2 diabetes (T2D) inadequately controlled on sitagliptin.
METHODS
Open-label, three-arm, 24-week trial; 582 insulin-naïve patients were randomized to twice-daily BIAsp 30+sitagliptin (BIAsp BID+Sit), once-daily BIAsp 30+sitagliptin (BIAsp QD+Sit) or twice-daily BIAsp 30 without sitagliptin (BIAsp BID), all with metformin.
RESULTS
After 24 weeks, HbA1c reduction (%) was superior with BIAsp BID+Sit vs. BIAsp QD+Sit (BIAsp BID+Sit minus BIAsp QD+Sit difference: -0.36 [95% CI -0.54; -0.17], P<0.001) and BIAsp BID (BIAsp BID minus BIAsp BID+Sit difference: 0.24 [0.06; 0.43], P=0.01). Observed final HbA1c values were 6.9%, 7.2% and 7.1% (baseline 8.4%), and 59.8%, 46.5% and 49.7% of patients achieved HbA1c <7.0%, respectively. Confirmed hypoglycaemia was lower with BIAsp QD+Sit vs. BIAsp BID (P=0.015); rate: 1.17 (BIAsp QD+Sit), 1.50 (BIAsp BID+Sit) and 2.24 (BIAsp BID) episodes/patient-year. Difference in bodyweight change favoured BIAsp QD+Sit vs. both BID groups (P<0.001).
CONCLUSIONS
Adding BIAsp 30 to patients with T2D poorly controlled with sitagliptin and metformin is efficacious and well tolerated; however, while BIAsp BID+Sit showed superior glycaemic control, BIAsp QD+Sit had a lower rate of hypoglycaemia and showed no weight gain.
