Exercise or Fasting in Individuals With Type 2 Diabetes Receiving Once‐Weekly Basal Insulin Icodec

Diabetes Obes MetabPublished Open-label crossover-style interventional study

Authors' conclusion

The current results reinforce the safety profile of once-weekly basal insulin icodec and provide guidance on glycaemic management during exercise or fasting in people with T2D treated with icodec.

Study context

Population
Basal insulin-treated, physically active adults with T2D (18–75 years, HbA1c ≤ 75 mmol/mol, peak oxygen uptake > 20 mL/kg/min) receiving once-weekly icodec for ≥ 7 weeks
Participants
30 participants
Comparison
Exercise week and fasting week vs reference week on once-weekly icodec
Outcome
CGM-based time below range < 3.0 mmol/L
Methodological detailssingle-group, reference week, exercise week and fasting week at icodec steady state, blinded continuous glucose monitoring (CGM)
