BackgroundInsulin degludec is a new-generation basal insulin with an ultra-long duration of action. We evaluated the pharmacokinetic properties of insulin degludec in subjects with normal renal function; mild, moderate or severe renal impairment; or end-stage renal disease (ESRD) undergoing hemodialysis.MethodsThirty subjects (n = 6 per group) received a single subcutaneous dose of 0.4 U/kg insulin degludec. Blood samples up to 120 h post-dose and fractionated urine samples were collected.ResultsThe ultra-long pharmacokinetic properties of insulin degludec were preserved in subjects with renal impairment, with no statistically significant differences in absorption or clearance, compared with subjects with normal renal function. In subjects with ESRD, pharmacokinetic parameters were similar whether the insulin degludec pharmacokinetic assessment period included hemodialysis or not, and total exposure was comparable to subjects with normal renal function. Simulated mean steady-state pharmacokinetic profiles were comparable between groups.ConclusionThis study indicated dose adjustments due to impaired renal function should not be required for insulin degludec.

Background and ObjectiveInsulin degludec is a basal insulin with a slow and distinct absorption mechanism resulting in an ultra-long, flat, and stable pharmacokinetic profile in patients with diabetes mellitus. The aim of this study was to examine the effect of hepatic impairment on the single-dose pharmacokinetics of insulin degludec.MethodsTwenty-four subjects, allocated to one of four groups (n = 6 per group) based on level of hepatic impairment (normal hepatic function, Child–Pugh grade A, B, or C), were administered a single subcutaneous dose of 0.4 U/kg insulin degludec. Blood samples up to 120 h post-dose and fractionated urine samples were collected to measure pharmacokinetic parameters.ResultsNo difference was observed in pharmacokinetic parameters [area under the 120-h serum insulin degludec concentration–time curve (AUC120 h), maximum insulin degludec concentration (Cmax), and apparent clearance (CL/F)] for subjects with impaired versus normal hepatic function after a single dose of insulin degludec. The geometric mean [coefficient of variation (CV) %] AUC120 h values were 89,092 (16), 83,327 (15), 88,944 (23), and 79,846 (19) pmol·h/L for normal hepatic function and mild, moderate, and severe hepatic impairment, respectively. Simulated steady-state insulin degludec pharmacokinetic profiles showed an even distribution of exposure across a 24-h dosing interval regardless of hepatic function status.ConclusionsThe ultra-long pharmacokinetic properties of insulin degludec were preserved in subjects with hepatic impairment and there were no statistically significant differences in absorption or clearance compared with subjects with normal hepatic function.

SD and MD of NNC0195-0092 administered to healthy Japanese and non-Asian male subjects were well tolerated at all doses. The present trial suggests that NNC0195-0092 has the potential for an efficacious, well-tolerated, once-weekly GH treatment.
