This study compared the pharmacokinetic and pharmacodynamic effects of a new insulin produced by Bioton S.A. with Humulin R produced by Eli Lilly. The results showed that both insulins are bioequivalent for treating type 1 diabetes patients.
Aims To compare the pharmacokinetic (PK) and pharmacodynamic (PD) effects and safety of therapeutic dosages of a regular insulin (experimental drug) produced by Bioton S.A. (Warsaw, Poland) versus Humulin (R) R, a regular insulin (reference drug) produced by Eli Lilly (Indianapolis, Indiana). Materials and Methods In a single-centre, randomized, double-blinded phase 1 crossover study, we used the manual euglycaemic clamp technique to compare PK and PD profiles between single subcutaneous doses (0.3 units/kg) of the two regular insulins in participants with type 1 diabetes (T1DM) with a washout period of 14 (+/- 7) days between tests. Results We evaluated 56 participants. The mean participant age and body mass index were 32.9 years and 22.9 kg/m(2), respectively. The ratios (experimental/reference) of the geometric means of maximum plasma insulin concentration and for plasma insulin area under the curve (AUC) were 0.909 (90% confidence interval [CI] 0.822-1.01) and 0.993 (90% CI 0.944-1.04), respectively. The ratios of the geometric means of maximum glucose infusion rate (GIR) and for GIR AUC were 0.999 (95% CI 0.912-1.09) and 1.04 (95% CI 0.962-1.12), respectively. Conclusions The experimental product regular human insulin and comparator Humulin (R) R are bioequivalent in patients with T1DM. Wider entry to the pharmaceutical market of affordable, biosimilar regular insulins may substantially improve access to insulin for many socioeconomically disadvantaged patients with diabetes.
