Abstract

To compare the efficacy and safety of weekly albiglutide with daily sitagliptin, daily glimepiride, and placebo.RESEARCH DESIGN AND METHODS: Patients with type 2 diabetes receiving metformin were randomized to albiglutide (30 mg), sitagliptin (100 mg), glimepiride (2 mg), or placebo. Blinded dose titration for albiglutide (to 50 mg) and glimepiride (to 4 mg) was based on predefined hyperglycemia criteria. The primary end point was change in HbA1c from baseline at week 104. Secondary end points included fasting plasma glucose (FPG), weight, and time to hyperglycemic rescue.RESULTS: Baseline characteristics were similar among the albiglutide (n = 302), glimepiride (n = 307), sitagliptin (n = 302), and placebo (n = 101) groups. Baseline HbA1c was 8.1% (65.0 mmol/mol); mean age was 54.5 years. The mean doses for albiglutide and glimepiride at week 104 were 40.5 and 3.1 mg, respectively. At week 104, albiglutide significantly reduced HbA1c compared with placebo (-0.9% [-9.8 mmol/mol]; P < 0.0001), sitagliptin (-0.4% [-4.4 mmol/mol]; P = 0.0001), and glimepiride (-0.3% [-3.3 mmol/mol]; P = 0.0033). Outcomes for FPG and HbA1c were similar. Weight change from baseline for each were as follows: albiglutide -1.21 kg (95% CI -1.68 to -0.74), placebo -1.00 kg (95% CI -1.81 to -0.20), sitagliptin -0.86 kg (95% CI -1.32 to -0.39), glimepiride 1.17 kg (95% CI 0.70-1.63). The difference between albiglutide and glimepiride was statistically significant (P < 0.0001). Hyperglycemic rescue rate at week 104 was 25.8% for albiglutide compared with 59.2% (P < 0.0001), 36.4% (P = 0.0118), and 32.7% (P = 0.1504) for placebo, sitagliptin, and glimepiride, respectively. Rates of serious adverse events in the albiglutide group were similar to comparison groups. Diarrhea (albiglutide 12.9%, other groups 8.6-10.9%) and nausea (albiglutide 10.3%, other groups 6.2-10.9%) were generally the most frequently reported gastrointestinal events.CONCLUSION: Added to metformin, albiglutide was well-tolerated; produced superior reductions in HbA1c and FPG at week 104 compared with placebo, sitagliptin, and glimepiride; and resulted in weight loss compared with glimepiride.
