Hormonal

Retatrutide significantly improves glycemic control, including reductions in HbA1c, fasting glucose, and daily mean blood glucose, in patients with obesity and/or type 2 diabetes.

For those with type 2 diabetes or obesity, retatrutide helps lower blood sugar levels (HbA1c, fasting glucose) effectively. This is achieved through weekly injections that mimic natural hormones to regulate glucose. The benefit is particularly pronounced for those who already have diabetes.

Also, there was a significant reduction in HbA1c (WMD –0.90 %; 95 % CI –1.63, – 0.17; p = 0.02; I2 = 89 %; Fig. 4A), daily mean blood glucose (WMD –2.07 mmol/L; 95 % CI –2.75, – 1.40; p < 0.01; I2 = 0 %; Fig. 4B), and fasting glucose (WMD –1.24 mmol/L; 95 % CI –2.24, – 0.23; p = 0.02; I2 = 75 %; Fig. 4C) in favor of the retatrutide group, compared with placebo.

Why this rating

Based on 3 RCTs with moderate to high heterogeneity (I2 up to 89% for HbA1c) and GRADE assessment of 'low-quality' evidence for HbA1c.
