843-P: Effects of Pemafibrate on Glucose Metabolism in Adults with Type 2 Diabetes and Hypertriglyceridemia—Subanalysis of the PARM-T2D Study

Background and Aims: Pemafibrate, a novel selective peroxisome proliferator-activated receptor modulator, has been demonstrated to have potent effects on abnormalities of lipid metabolism in adults with type 2 diabetes (T2DM) and hypertriglyceridemia in real-world clinical practice (PARM-T2D study). However, the effects of pemafibrate on glucose metabolism have not been fully clarified. Materials and Methods: In this multicenter, open-labeled, prospective, observational study, adults with T2DM were treated with pemafibrate (PEMA group) or continued on their current therapy (CTRL group) for dyslipidemia for 52 weeks. This subanalysis consisted of participants who did not change their treatment for diabetes and who did not receive insulin or insulin secretagogues during the study period. Glycemic control, insulin secretion, and insulin resistance were assessed by HbA1c levels, HOMA2-β, and HOMA2-R, respectively. The changes of these parameters between baseline and the end of the study were compared between the groups. Results: In total, 279 of 650 participants met the criteria for this analysis. There were no statistical differences in baseline characteristics between PEMA (n = 141) and CTRL groups (n = 138). There were no significant changes in HbA1c levels and beta-cell function over 52 weeks between the groups, whereas pemafibrate significantly improved insulin resistance assessed by HOMA2-R versus the CTRL group (−0.20 vs. 0.01; estimated treatment difference, −0.23% [95% confidence interval = −0.44, −0.02]; p
