ABSTRACT

AIMS/INTRODUCTION: The present phase 3, randomized, double-blind 24-week study with extension to 1 year assessed the efficacy and safety of albiglutide compared with placebo in Japanese patients with type 2 diabetes mellitus inadequately controlled by diet and exercise with or without a single oral antidiabetic drug. MATERIALS AND METHODS: Patients received weekly albiglutide 30 mg (n = 160), albiglutide 50 mg (n = 150) or a placebo switched to albiglutide 30 mg after 24 weeks (n = 77). Open-label daily liraglutide 0.9 mg (n = 103) was included as a reference. Oral antidiabetic drug use was discontinued before baseline. The primary end-point was 24-week change from baseline in glycated hemoglobin (HbA1c). Secondary end-points included fasting plasma glucose, bodyweight and adverse events. RESULTS: At 24 weeks, mean HbA1c changes from baseline were -1.10, -1.30, and 0.25% for albiglutide 30, 50 mg and placebo, respectively (P vs placebo <0.0001 for both albiglutide doses), -1.19% for liraglutide. Decreases in HbA1c with albiglutide were sustained through the study. Mean fasting plasma glucose decreased by ≥20 mg/dL, and the mean change in bodyweight was ≤0.5 kg through 1 year across groups. Most commonly reported adverse events were nasopharyngitis, constipation and nausea. The incidence of adverse events was higher in active treatment groups than in the placebo group. Few hypoglycemia events were reported; no patient withdrew as a result of hypoglycemia. No new safety signals were detected. CONCLUSIONS: Albiglutide monotherapy achieved clinically significant decreases in HbA1c and fasting plasma glucose with good tolerability in Japanese patients with type 2 diabetes mellitus inadequately controlled by diet and exercise with or without a single oral antidiabetic drug.

ABSTRACT

OBJECTIVE: To evaluate the safety and efficacy of once weekly albiglutide added to a single oral antidiabetic drug (OAD) in Japanese patients with inadequately controlled type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS: In this phase 3, 1 year study (NCT01777282), patients (N = 374) received albiglutide 30 mg plus a single OAD (sulfonylurea [n = 120], biguanide [n = 67)], glinide [n = 65], thiazolidinedione [n = 61], or α-glucosidase inhibitor [n = 61]). Albiglutide could be increased to 50 mg after Week 4, based on glycemic criteria. Primary endpoints were the incidence of adverse events (AEs) and hypoglycemia; secondary endpoints were changes from baseline at Week 52 in HbA1c and fasting plasma glucose (FPG), proportion of patients achieving HbA1c ≤7.0%, and withdrawals due to hyperglycemia. RESULTS: On-therapy AEs occurred in 78.6% of patients and serious AEs in 2.1%. Common AEs were nasopharyngitis (32.6%), constipation (7.2%), and diabetic retinopathy (5.3%). No serious AEs occurred more than once or were reported in >1 patient. Hypoglycemia occurred in 6.4% of patients, mostly in the albiglutide + sulfonylurea (14.2%) and the albiglutide + glinide (6.2%) groups. Albiglutide was uptitrated in 53.2% of patients. Mean baseline HbA1c was 8.1%. Mean decreases from baseline in HbA1c were observed with the addition of albiglutide to thiazolidinediones (-1.42%), α-glucosidase inhibitors (-1.39%), sulfonylureas (-1.04%), glinides (-0.95%), and biguanides (-0.94%). HbA1c of <7% in >50% of patients and mean reductions in FPG were achieved in all groups. Mean changes from baseline in body weight ranged from +0.52 kg (albiglutide + thiazolidinedione) to -0.33 kg (albiglutide + biguanide). Limitations of the study included open label treatment that was not randomized. CONCLUSIONS: When combined with a single OAD in Japanese patients with inadequately controlled T2DM, albiglutide led to favorable changes in all glycemic parameters, with minor changes in body weight depending on the background OAD. No new safety concerns were noted.

ABSTRACT

OBJECTIVE: To investigate the optimal dosage/regimen and to evaluate the efficacy and safety of albiglutide in Japanese patients with type 2 diabetes mellitus. RESEARCH DESIGN AND METHODS: This was a randomized, double-blind, placebo-controlled, multicenter, parallel-group, dose-ranging, superiority study in Japanese patients with type 2 diabetes mellitus. Patients (n = 215) who were treatment naive or washed out of one oral antidiabetic drug were randomized to placebo or albiglutide 15 mg weekly, 30 mg weekly, or 30 mg every other week (biweekly). CLINICAL TRIAL REGISTRATION: NCT01098461. MAIN OUTCOME MEASURES: The primary end point was the change from baseline in HbA1c at week 16, measured using the Japan Diabetes Society standardization scheme and presented here using the National Glycohemoglobin Standardization Program equivalents. Other measures of efficacy as well as safety and population pharmacokinetics and pharmacokinetics/pharmacodynamics of albiglutide were assessed. RESULTS: Baseline HbA1c was 8.53%. There was a statistically significant difference between each albiglutide treatment group and placebo for change from baseline in HbA1c at week 16, with treatment effects of -0.89% for 15 mg weekly, -1.55% for 30 mg weekly, and -1.10% for 30 mg biweekly (P < 0.0001 for all groups vs placebo). By week 16, 63.0% and 33.3% of patients in the 30 mg weekly albiglutide group compared with 6.0% and 0% of patients in the placebo group achieved HbA1c <7.4% and <6.9%, respectively. No serious adverse events were related to study therapy; no deaths occurred. Nasopharyngitis was the most frequently reported adverse event in all treatment groups (n = 43 [20.3%]). CONCLUSIONS: Albiglutide exhibited therapeutic hypoglycemic effects with good tolerability among Japanese patients with type 2 diabetes mellitus; the 30 mg weekly dose was the most efficacious in this study. The 16 week duration of the study prevents generalizing these conclusions to longer treatment periods.
