Pharmacokinetic and pharmacodynamic equivalence of Biocon's biosimilar insulin N with US-licensed Humulin® N formulation in healthy subjects: Results from the RHINE-2 (Recombinant Human INsulin Equivalence-2) study.

AIM: To establish the pharmacokinetic (PK) and pharmacodynamic (PD) equivalence of proposed biosimilar Insulin N (Biocon's Insulin-N; Biocon Biologics Ltd., Bangalore, India) and US-licensed Humulin® N (Humulin-N; Eli Lilly and Company, Indianapolis, IN, USA) in healthy subjects. MATERIALS AND METHODS: This was a phase-1, single-centre, double-blind, randomized, three-period, six-sequence, partially replicated, crossover, 24-h euglycaemic clamp study. Overall, 90 healthy subjects were randomized, of whom 85 completed the study. The subjects received either two single doses of Biocon's Insulin-N and a single dose of Humulin-N or two single doses of Humulin-N and a single dose of Biocon's Insulin-N subcutaneously at a dose of 0.4 IU/kg. The primary PK endpoints were the area under the insulin concentration-time curve from 0 to 24 h (AUCins.0-24h ) and the maximum insulin concentration (Cins.max ). The primary PD endpoints were the area under the glucose infusion rate (GIR) curve from 0 to 24 h (AUCGIR.0-24h ) and the maximum GIR (GIRmax ). RESULTS: Biocon's Insulin-N was found to be equivalent to Humulin-N for the primary PK (geometric 90% confidence interval for the least squares mean ratio: AUCins.0-24h , 100.98%-115.66% and Cins.max , 95.91%-110.16%) and PD endpoints (intra-subject variability ≥0.294; 95% upper confidence interval [(µT - µR)2 - θσ2 WR] <0; point estimates of geometric least squares mean ratio: AUCGIR.0-24h , 104.61% and GIRmax , 100.81%). The safety profile of Biocon's Insulin-N was similar to that of Humulin-N, and no serious adverse events were reported. CONCLUSION: PK and PD equivalence was shown between Biocon's Insulin-N and Humulin-N in healthy subjects, and both treatments were well tolerated and considered safe.

Efficacy and safety of Tregopil, a novel, ultra-rapid acting oral prandial insulin analog, as part of a basal-bolus regimen in type 2 diabetes: a randomized, active-controlled phase 2/3 study.

BACKGROUND: Efficacy and safety of ultra-rapid acting oral prandial insulin Tregopil was compared with insulin aspart (IAsp) in patients with type 2 diabetes (T2D) on insulin glargine and metformin. RESEARCH DESIGN AND METHODS: In this open-label, active-controlled trial, patients with T2D, HbA1c ≥7%-≤9% and 2-h postprandial glucose (PPG) ≥180 mg/dL were randomized 1:1:1 to Tregopil (30 mg, n = 30; 45 mg, n = 31) and IAsp, n = 30. Primary outcome was change from baseline (CFB) in HbA1c at week 24. Secondary outcomes included PPG excursion (PPGE) and PPG assessed from standardized test meal (STM) and 9-point self-monitored blood glucose. RESULTS: The observed mean HbA1c did not improve at week 24 in Tregopil groups (30 mg [0.15%], 45 mg [0.22%] vs. a reduction in IAsp group [-0.77%]). Combined Tregopil group showed better 1-h PPGE control versus IAsp following STM (CFB, estimated treatment difference, 95% CI, -45.33 mg/dL [-71.91, -18.75], p = 0.001) and 1-h PPG trended toward better control. Tregopil showed lower PPGE at 15 min versus IAsp. Clinically significant hypoglycemia was lower with Tregopil versus. IAsp (rate ratio: 0.69). CONCLUSIONS: Tregopil demonstrated an ultrafast, short-duration prandial profile with good safety. While Tregopil's early postprandial effects were comparable to IAsp, its late postprandial effects were inferior. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT03430856).

Pharmacokinetic and pharmacodynamic equivalence of Biocon's biosimilar Insulin 70/30 with US-licensed HUMULIN® 70/30 formulation in healthy subjects: Results from the RHINE-3 (Recombinant Human INsulin Equivalence-3) study.

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.

Pharmacokinetic and pharmacodynamic equivalence of Biocon's biosimilar Insulin-R with the US-licensed Humulin® R formulation in healthy subjects: Results from the RHINE-1 (Recombinant Human INsulin Equivalence-1) study.

AIM: To establish equivalence in the pharmacokinetic (PK) and pharmacodynamic (PD) endpoints between proposed biosimilar Insulin-R (Biocon's Insulin-R) and Humulin® R using the euglycaemic clamp technique in healthy subjects. MATERIALS AND METHODS: In this phase-1 automated euglycaemic glucose clamp study, 42 healthy subjects were randomized (1:1) to receive a single dose of 0.3 IU/kg of Biocon's Insulin-R and Humulin-R. Plasma insulin concentrations and glucose infusion rates (GIRs) were assessed over 12 hours. Primary PK endpoints were area under the insulin concentration-time curve from 0 to 12 hours (AUCins.0-12h ) and maximum insulin concentration (Cins.max ). Primary PD endpoints were area under the GIR time curve from 0 to 12 hours (AUCGIR.0-12h ) and maximum GIR (GIRmax ). RESULTS: Equivalence was demonstrated between Biocon's Insulin-R and Humulin-R for the primary PK and PD endpoints. The 90% confidence intervals were within 80.00% to 125.00% limits. The PK and PD profiles were comparable. There were no significant differences in the safety profiles of the two treatments, and no serious adverse events were reported. CONCLUSION: PK and PD equivalence was demonstrated between Biocon's Insulin-R and Humulin-R in healthy subjects. Treatment with Biocon's Insulin-R and Humulin-R was well tolerated.
