Abstract –

Aim: To establish the pharmacokinetic (PK) and pharmacodynamic (PD) equivalence of proposed biosimilar insulin 70/30 (Biocon’s Insulin-70/30) and HUMULIN® 70/30 (HUMULIN-70/30; Eli Lilly and Company, IN).

Materials and methods: In this phase 1, automated euglycaemic glucose clamp study, 78 healthy subjects were randomized (1:1) to receive a single dose of 0.4 IU/kg of Biocon’s Insulin-70/30 and HUMULIN-70/30. Plasma insulin concentrations and glucose infusion rates (GIRs) were assessed over 24 hours. Primary PK endpoints were area under the insulin concentration-time curve from 0 to 24 hours – AUCins.0-24h – and maximum insulin concentration – Cins.max . Primary PD endpoints were area under the GIR time curve from 0 to 24 hours – AUCGIR.0-24h – and maximum GIR – GIRmax .

Results: Equivalence was shown between Biocon’s Insulin-70/30 and HUMULIN-70/30 for the primary PK/PD endpoints. The 90% confidence intervals of the treatment ratios were entirely within the acceptance range of 80.00%-125.00%. The secondary PK/PD profiles were also comparable. There were no clinically relevant differences in the safety profiles of the two treatments and no serious adverse events were reported.

Conclusion: PK/PD equivalence was demonstrated between Biocon’s Insulin-70/30 and HUMULIN-70/30 in healthy subjects. Treatment with Biocon’s Insulin-70/30 and HUMULIN-70/30 was well tolerated.
