Tolerability and efficacy of glycemic control with saxagliptin in older patients (aged ≥ 65 years) with inadequately controlled type 2 diabetes mellitus
Abstract
PURPOSE: To assess safety and efficacy of saxagliptin in older patients with type 2 diabetes mellitus (T2DM).
PATIENTS AND METHODS: This was a post hoc analysis of pooled data from older patients (≥65 years of age) from five 24-week phase III trials: three studies of saxagliptin versus placebo as an add-on therapy to metformin, glyburide, or a thiazolidinedione; and two studies of saxagliptin versus placebo as monotherapy in drug-naïve patients. Separate analyses were conducted on one study of initial combination therapy with saxagliptin plus metformin versus metformin monotherapy in drug-naïve patients. The safety analysis population for the five-study pool included 428 patients ≥ 65 years of age with baseline glycated hemoglobin (HbA(1c)) 7.0% to 10.5% who received saxagliptin 2.5 or 5 mg or placebo, and for the study of initial combination therapy included 69 patients ≥ 65 years of age with baseline HbA(1c) 8.0% to 12.0% who received saxagliptin 5 mg in combination with metformin or metformin monotherapy. The primary efficacy endpoint was change from baseline HbA(1c).
RESULTS: In the five-study pool, the differences in the adjusted mean change from baseline HbA(1c) among older patients receiving saxagliptin versus placebo were -0.60% (95% confidence interval [CI], -0.99% to -0.21%) for saxagliptin 2.5 mg and -0.55% (-0.97% to -0.14%) for saxagliptin 5 mg; in the initial combination study, the difference was -1.22% (-2.27% to -0.17%) among older patients receiving…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 428 participants or records.
