Comparison between insulin degludec/liraglutide treatment and insulin glargine/lixisenatide treatment in type 2 diabetes: a systematic review and meta-analysis.

AIM: To evaluate the efficacy and adverse effects of IDegLira and IGlarLixi treatment and to perform a comparison between two strategies. METHODS: The registration number is CRD42017053952. Randomized controlled trials of IGlarLixi treatment or IDegLira treatment compared with placebo or active hypoglycemic agents in type 2 diabetes were included. RESULTS: Eight trials were included. The absolute HbA1c change relative to baseline after IGlarLixi treatment was -1.50% with significance (95% CI, -1.89% to -1.12%, p < 0.01); the absolute HbA1c change after IDegLira treatment was -1.89% with significance (95% CI, -2.04% to -1.73%, p < 0.01). Comparisons between IGlarLixi treatment and IDegLira treatment indicated no significant differences between groups. The absolute weight change after IGlarLixi treatment significantly decreased (weighted mean difference (WMD), -0.62 kg; 95% CI, -0.93 to -0.31 kg, p = < 0.01), but the absolute weight change after IDegLira treatment was not significantly changed (WMD, -0.81 kg; 95% CI, -3.26 to 1.65 kg, p = 0.52). There were no significant differences between groups. CONCLUSION: Glucose control of IGlarLixi treatment or IDegLira treatment was significantly lower than that at baseline. Comparisons between the two treatment groups indicated no significant differences between groups in absolute HbA1c changes or body weight changes relative to baseline.
