Efficacy and hypoglycaemia outcomes with once‐weekly insulin icodec versus once‐daily basal insulin in individuals with type 2 diabetes by kidney function: A post hoc participant‐level analysis of the ONWARDS 1–5 trials

Diabetes Obes MetabPublished Post hoc participant-level analysis of the ONWARDS 1–5 randomised trials

Authors' conclusion

Efficacy and hypoglycaemia outcomes of icodec versus once-daily comparators were generally consistent among adults with T2D, regardless of kidney function.

Study context

Population
Insulin-naive (ONWARDS 1, 3 and 5) and insulin-experienced (ONWARDS 2 and 4) adults aged ≥18 years with T2D, by kidney function subgroup (eGFR ≥90; 60-<90; 30-<60; <30 mL/min/1.73m2); eGFR <30 excluded in ONWARDS 1–4 but not ONWARDS 53,763 analysed
Participants
3,765 participants
Comparison
Once-weekly insulin icodec vs once-daily basal insulin
Methodological detailssubgroup analysis by kidney function
  • Subgroup analysis by kidney function

Primary result

As reported in the abstract

Change in HbA1c by kidney function subgroup · baseline to end of treatment
  • No statistically significant treatment interactions by kidney function subgroup in ONWARDS 1, 3 and 5
  • Icodec vs Once-daily basal insulin: P for interaction < 0.05 (ONWARDS 2 and 4, both)

Further findings

OutcomeP value
HbA1c <7% without clinically significant or severe hypoglycaemiaNo statistically significant interactionsall p-interaction >0.05

Change in body weight by kidney function subgroup · baseline to end of treatment

Comparable between treatment arms across kidney function subgroups

Mean weekly insulin dose, last 2 weeks of treatment

No consistent trend by kidney function subgroup across trials

Safety

Combined clinically significant or severe hypoglycaemia rates

No consistent trend by kidney function subgroup across trials
