A Multinational, Observational Study to Investigate the Efficacy, Safety and Tolerability of Acarbose as Add-On or Monotherapy in a Range of Patients: The GlucoVIP Study (original) (raw)

Background and Objectives The burden of type 2 diabetes mellitus is growing rapidly, particularly in the Asia-Pacific region. The aim of this international, largescale, observational study was to investigate the efficacy and tolerability of the antidiabetic agent acarbose as add-on or monotherapy in a range of patients with type 2 diabetes, including those with cardiovascular morbidities. The majority of practices were included from high-burden regions (predominantly those in the Asia-Pacific region). Methods This was an observational study conducted in 15 countries/regions. Adults with pre-treated or untreated type 2 diabetes prescribed acarbose as add-on or monotherapy were eligible. Two-hour postprandial blood glucose (2-h PPG), glycosylated haemoglobin (HbA 1c) and fasting blood glucose (FBG) were measured over a 3-month observation period. Results A total of 15,034 patients were valid for the efficacy analysis and 15,661 for the safety analysis (mean age was 57.6 years and 92.6 % of patients were Asian). Mean (SD) 2-h PPG decreased by-71.9 (62.3) mg/dL, to 170.2 (46.5) mg/dL at final visit (after 12.8 [4.1] weeks). Mean HbA 1c decreased by-1.1 % (1.3) to 7.2 % (1.1) and mean FBG decreased by-33.0 (43.3) mg/dL to 124.8 (30.5) mg/dL. Acarbose was effective regardless of the presence of cardiovascular co-morbidities or diabetic complications. The efficacy of acarbose was rated 'very good' or 'good' in 85.5 % of patients, and tolerability as 'very good' or 'good' in 84.9 % of patients. Drug-related adverse events, mainly gastrointestinal, were reported in 490/15,661 patients (3.13 %). Conclusion The results of this observational study support the notion that acarbose is effective, safe and well tolerated in a large cohort of Asian patients with type 2 diabetes.
