Authors' conclusion

Among adults with basal insulin-treated type 2 diabetes, treatment with once-weekly icodec versus once-daily degludec demonstrated non-inferiority and statistical superiority in HbA1c reduction after 26 weeks, associated with modest weight gain. Overall rates of hypoglycaemia were low, with numerically but not statistically significantly higher event rates of level 2 or level 3 hypoglycaemia with icodec versus degludec.
