Evaluating the efficacy and safety of weekly Insulin Icodec vs. Daily Insulin Glargine in type 2 Diabetes Mellitus: a systematic review and meta-analysis

Various insulin therapies for Diabetes Mellitus offer different benefits while having potential risks. We aim to compare Insulin Icodec, a novel Insulin analogue with the ease of once-weekly administration, to the once-daily Insulin Glargine U100 regarding glycemic control and safety profile.

We performed a systematic literature search of electronic databases for peer-reviewed articles from inception until September 1 2023.

A total of 2215 type 2 diabetic patients were included, of which 1209 received Insulin Icodec and1048 recieved Insulin Glargine U100. In terms of glycemic control, Insulin Icodec showed a significantly longer time in the target glucose range (MD: 0.304, CI: 0.069, P = 0.000) and a more significant reduction in HbA1c (MD: -0.154, CI: 0.003, P = 0.005) compared to Insulin Glargine U100. Fasting Plasma Glucose did not differ significantly. Insulin Icodec led to a more significant increase in body weight (MD: 0.161 kg, P = 0.029), while Insulin Glargine required a higher insulin dose (MD: 1.920 IU, P = 0.000). Regarding safety, the two groups had no significant differences in hypoglycemic events or adverse outcomes.

Once-weekly Insulin Icodec demonstrates superior glycemic control with a reduced HbA1c compared to Once-Daily Insulin Glargine U100 while maintaining similar safety profiles.
