Effectiveness prediction of Evogliptin treatment in type 2 diabetes mellitus in russian-korean population

| Sumario: | Background: Individualized treatment has already become a part of a routine clinical care. Many data on the effectiveness prediction of commercially available DPP-4 inhibitors had been published, but not on the effectiveness prediction of evogliptin.
Aim: To reveal the clinical characteristics and metabolic predictors of better hypoglycemic response to evogliptin. Matherials and methods: We have conducted a retrospective study, based on the data of a randomized clinical trial comparing effectiveness and safety of evogliptin and sitagliptin in Russian and Korean subpopulations. We provide univariate linear regression models for separate subpopulations and a multivariate stepwise regression model for the combined subpopulation. HbA1c change after 24 weeks of evogliptin treatment was a primary endpoint and a dependent variable in the analysis.
Results: The decrease of HbA1c after 24 weeks of treatment with evogliptin in Russian subpopulation negatively correlates with triglycerides/HDL level (p = 0,046). In South Korean subpopulation it correlates positively with HbA1c level at baseline (p < 0,0001). In order to increase the statistical power of the analysis the data of both populations were combined. According to the combined data, the decrease of HbA1c after 24 weeks of treatment with evogliptin positively correlates with HbA1c level at baseline (p<0.0001) and log(HOMA-B) (p=0.0042), and it negatively correlates with log(triglycerides/HDL) (p=0.0057), blood phosphorous concentration (p=0.014) and statin treatment (p=0.044). No correlation of HbA1c change at week 24 was observed with body mass index, diabetes duration and blood C-peptide concentration. Patients able to achieve HbA1c<7,0 % had higher HOMA-B (53.22 ± 36.95 и 39.67 ± 24.74, respectively, р=0.033) and were tend to have higher HDL concentration (1.36 ± 0.28 и 1.26 ± 0.26 mmol/l, respectively, р=0.076) and lower triglycerides to HDL ratio (0.87 ± 0.70 и 1.48 ± 0.95, respectively, р=0.079).
Conclusion: A patient, who benefits more when treated with evogliptin, has higher HOMA-B, lower triglycerides to HDL ratio and phosphorous concentration in the 1-2 quartiles of the normal range. Triglycerides to HDL ratio is, probably, a specific effectiveness predictor for Russian, but not for Korean subpopulation. These data prove the difference in effectiveness prediction for different drugs of DPP-4 inhibitors group and reveal the need of further investigation. |
