To assess the long-term efficacy and safety of saxagliptin in patients with type 2 diabetes mellitus inadequately controlled on sulphonylurea monotherapy, 768 patients were randomised to saxagliptin 2.5 or 5 mg in combination with glyburide 7.5 mg versus placebo added to up-titrated glyburide over 76 weeks (24 weeks plus 52-week extension) in this phase 3, double-blind, placebo-controlled trial; 557 patients completed the study, 142 without being rescued. At 76 weeks, adjusted mean changes from baseline HbA(1C) (repeated measures model) (95% confidence interval) for saxagliptin 2.5 mg, saxagliptin 5 mg, and up-titrated glyburide were 0.11% (-0.05, 0.27), 0.03% (-0.14, 0.19), and 0.69% (0.47, 0.92), respectively (post hoc and nominal p < 0.0001 for saxagliptin 2.5 and 5 mg vs. up-titrated glyburide). Adverse event frequency was similar in all treatment groups; reported hypoglycaemia event rates were 24.2%, 22.9%, and 20.6% with saxagliptin 2.5 mg, saxagliptin 5 mg, and up-titrated glyburide, respectively. Saxagliptin plus glyburide provided sustained incremental efficacy compared with up-titrated glyburide over 76 weeks, and was generally well tolerated.
