Effect of patient characteristics on the efficacy and safety of imeglimin monotherapy in Japanese patients with type 2 diabetes mellitus: A post‐hoc analysis of two randomized, placebo‐controlled trials

AIMS/INTRODUCTION: Substantial variability in demographic and clinical characteristics exists among patients with type 2 diabetes mellitus, which may impact treatment. This post‐hoc analysis evaluated the efficacy and safety of imeglimin 1,000 mg twice daily (BID) monotherapy in type 2 diabetes mellitus patients according to demographic and clinical characteristics. MATERIALS AND METHODS: Data were pooled from two placebo‐controlled, 24 week, randomized, double‐blind studies in adults with type 2 diabetes mellitus. Outcomes (least squares mean [LSM] change in HbA1c from baseline to week 24, and safety) were analyzed according to subgroups based on demographics, clinical characteristics, and comorbidities. RESULTS: The difference in LSM change in HbA1c from baseline to week 24 was statistically significant for imeglimin vs placebo in all patient subgroups analyzed (P < 0.05 each), including demographics (age, body mass index), clinical characteristics (duration of type 2 diabetes mellitus, chronic kidney disease [CKD] stage, and prior medication use) and comorbidities (hypertension, dyslipidemia, risk of hepatic fibrosis and liver function parameter status). A statistically significant separation from placebo in HbA1c was observed at week 4 and maintained through week 24. No new safety concerns were identified with imeglimin in any patient subpopulations. CONCLUSIONS: The efficacy and safety of imeglimin was demonstrated across patient subgroups, irrespective of baseline demographic and clinical characteristics. Our findings confirm the efficacy and safety of imeglimin across a broad spectrum of patients with type 2 diabetes mellitus.
