Individual doses were determined during run-in with glargine U100 titrated to prebreakfast self-measured plasma glucose (SMPG) of 4.4–7.2 mmol/L. Blood samples for icodec pharmacokinetics were taken from the first icodec dose until 35 days after last dose. The steady-state glucose-lowering effect was measured in glucose clamps (target 6.7 mmol/L) during 24–48 h and 150–168 h after last icodec dose and 0–24 h after last glargine U100 dose.
