title: A post hoc analysis of saxagliptin efficacy and safety in patients with type 2 diabetes stratified by UKPDS 10-year cardiovascular risk score.
abstract: To assess the efficacy and safety of saxagliptin 2.5 and 5 mg/d in patients with type 2 diabetes mellitus (T2DM) and high risk of coronary heart disease (CHD) or stroke as estimated by the United Kingdom Prospective Diabetes Study (UKPDS) risk engine.
  
  
  
  Post hoc analysis of data pooled from 5 previously reported phase 3, randomized, placebo-controlled, 24-week studies was conducted. Patients were stratified into subgroups by UKPDS 10-year CHD and/or stroke risk ≥20% and CHD and stroke risk <20%. End points were adjusted mean change from baseline in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), 120-min postprandial glucose (PPG), and body weight and the proportion of patients achieving HbA1c <7% and ≤8% at week 24. Pooled safety data were analyzed for adverse events (AEs) and hypoglycemia. Both doses of saxagliptin reduced HbA1c, FPG, and PPG to a greater extent than placebo regardless of UKPDS risk score. The proportions of patients achieving HbA1c <7% and ≤8% were greater with saxagliptin than placebo and consistent across risk score groups. AE profile and hypoglycemia incidence were similar for saxagliptin and placebo across UKPDS risk score groups.
  
  
  
  Saxagliptin was well tolerated and improved glycemic control in patients with T2DM regardless of their CHD and stroke UKPDS risk score. Clinical trial registration numbers: Clinicaltrials.gov NCT00121641, NCT00316082, NCT00121667, NCT00313313, and NCT00295633.
