Background: SAR341402 insulin aspart (SAR-Asp) is a rapid-acting insulin analog developed as an interchangeable biosimilar to the marketed insulin aspart reference product (NovoLog; NN-Asp). GEMELLI X was a randomized controlled trial to assess outcomes with a biosimilar in line with the US Food and Drug Administration requirements for designation as an interchangeable biosimilar. This report assessed whether multiple switches between SAR-Asp and NN-Asp lead to equivalent safety and efficacy compared with continuous use of NN-Asp in adults with type 1 diabetes (T1D) treated with multiple daily injections, using once-daily insulin glargine U100 (Lantus) as the basal insulin., Methods: This open-label randomized (1:1), parallel-group, phase 3 trial compared four × four weeks of alternating use of individually titrated SAR-Asp and NN-Asp (NN-Asp for first four weeks, SAR-Asp in last four weeks; switching group) vs 16 weeks of continuous use of NN-Asp (nonswitching group). End points included pharmacokinetics, immunogenicity, adverse events, hypoglycemia, insulin dose, and change in efficacy parameters., Results: Of the 210 patients randomized, 200 (95.5%) completed the trial. Patients assigned to switching group (n = 104) and nonswitching group (n = 106) showed similar safety and tolerability, including anti-insulin aspart antibody responses, adverse events, and hypoglycemia. At week 16, there was no relevant difference between switching vs nonswitching groups in the change from baseline in glycated hemoglobin (least square [LS] mean difference = 0.05% [95% confidence interval [CI] = -0.13, 0.22]; 0.50 mmol/mol [-1.40, 2.39]), fasting plasma glucose (LS mean difference = 0.23 mmol/L [95% CI = -1.08, 1.53]; 4.12 mg/dL [-19.38, 27.62]), and changes in insulin dosages., Conclusions: Alternating doses of SAR-Asp and NN-Asp compared with continuous use of NN-Asp showed similar safety, immunogenicity, and clinical efficacy in adults with T1D.

Aim: To assess whether multiple switches between SAR341402 biosimilar insulin aspart (SAR-Asp) and the insulin aspart reference product (NovoLog; NN-Asp) leads to equivalent pharmacokinetic (PK) exposure compared with continuous use of NN-Asp in adults with type 1 diabetes (T1D)., Materials and Methods: This multicentre, open-label, phase 3 study randomized (1:1) 210 subjects with T1D treated with once-daily insulin glargine U100 as basal insulin to four 4-week periods of alternating multiple daily injections of SAR-Asp and NN-Asp (NN-Asp for the first 4 weeks, SAR-Asp in the last 4 weeks; switching group) versus 16 weeks of continuous NN-Asp (non-switching group). At week 16, a single dose (0.15 U/kg) of SAR-Asp in the switching group (n = 95) or NN-Asp in the non-switching group (n = 105) was given in the morning before breakfast. Primary PK endpoints were area under the plasma concentration curve (AUC) and maximum plasma concentration (C max ) of SAR-Asp versus NN-Asp after the single dose at week 16., Results: The extent of PK exposure was similar between the two treatments (SAR-Asp in the switching group and NN-Asp in the non-switching group) at week 16, with point estimates of treatment ratios close to 1. The 90% confidence intervals for AUC treatment ratios were contained within 0.8-1.25. For C max in the primary analysis set, the upper confidence limit was 1.32. This was because of the profiles of three participants with implausible high values. A prespecified sensitivity analysis excluding implausible values showed results contained within 0.8-1.25., Conclusions: PK exposure of SAR-Asp (switching group) and reference NN-Asp (non-switching group) were similar, supporting interchangeability between these two insulin aspart products., (© 2023 The Authors.

Introduction: We compared the efficacy, safety, and immunogenicity of biosimilar insulin aspart premix SAR341402 Mix 70/30 (70% intermediate SAR341402 protamine and 30% rapid SAR341402 solution) (SAR Asp -Mix) with its originator NovoMix 30 insulin aspart mix (NN-Mix) in adults with type 1 or type 2 diabetes switching from different premix insulin analogs., Methods: This phase 3, randomized, open-label, multinational, 26-week trial (GEMELLI M) enrolled 402 participants with type 1 or type 2 diabetes. At randomization, participants switched from their prestudy premix insulin NovoMix 30 (n = 341) or Humalog Mix 25/Liprolog Mix 25 (n = 61) to equivalent (1:1) doses of either SAR Asp -Mix or NN-Mix at least twice daily (1:1 randomization). In this subgroup analysis, efficacy measures [change in hemoglobin A1c (HbA1c), daily insulin dose], and safety outcomes [hypoglycemia incidence, adverse events (including hypersensitivity and injection site reactions), anti-insulin aspart antibodies] of SAR Asp -Mix were compared with those of NN-Mix separately according to the participants' prestudy premix insulin., Results: At week 26, change from baseline in HbA1c (primary efficacy endpoint) was similar between SAR Asp -Mix and NN-Mix in those participants pretreated with NovoMix 30 [least squares (LS) mean difference 0.05%, 95% confidence interval (CI)  -0.195% to 0.289%] or Humalog Mix 25/Liprolog Mix 25 (LS mean difference 0.28%, 95% CI -0.279% to 0.830%) (P value for treatment-by-subgroup interaction = 0.46). In both subgroups, safety outcomes, including immunogenicity, and changes in daily insulin doses were similar between treatments over 26 weeks., Conclusions: Efficacy, safety, and immunogenicity profiles of SAR Asp -Mix are similar to NN-Mix over 26 weeks in adults with diabetes irrespective of prior type of premix insulin., Trial Registration: EudraCT number 2017-000092-84., (© 2022.

Introduction: This study compared the efficacy, safety, and immunogenicity of biosimilar insulin aspart premix SAR341402 Mix 70/30 (SAR Asp -Mix) with European-approved insulin aspart mix 70/30 - NovoMix® 30 (NN-Mix) in people with type 1 (T1D) or type 2 diabetes (T2D)., Methods: This 26-week, open-label, phase 3 trial enrolled 402 people with T1D (n = 105) or T2D (n = 297) previously treated with premix insulin, who were randomized (1:1) to SAR Asp -Mix (n = 204) or NN-Mix (n = 198)., Results: After 26 weeks, the least squares (LS) mean [median] change in HbA1c from baseline was similar in both treatment groups (SAR Asp -Mix - 0.55% [- 0.60%]; NN-Mix - 0.64% [- 0.60%]). The LS mean difference for SAR Asp -Mix versus NN-Mix was 0.08%, with the upper bound of the two-sided 95% confidence interval (- 0.139 to 0.303) slightly above the prespecified noninferiority margin of 0.3%. Noninferiority of SAR Asp -Mix over NN-Mix was not demonstrated in the primary intent-to-treat analysis, primarily because of one extreme outlying value impacted by the COVID-19 pandemic in the SAR Asp -Mix group. Noninferiority was achieved in all secondary analyses, including prespecified per-protocol supportive and COVID-19 sensitivity analyses, as well as post hoc sensitivity analyses. Other efficacy endpoints, insulin dosages, anti-insulin aspart antibody response, hypoglycemia, and adverse events were similar between groups., Conclusions: The totality of evidence indicates that SAR Asp -Mix provides effective glycemic control with a similar safety and immunogenicity profile to NN-Mix in people with diabetes treated for 26 weeks., Trial Registration: EudraCT number 2017-000092-84., (© 2022.

Introduction: The biosimilar SAR341402 insulin aspart (SAR-Asp) was compared to its originator NovoLog®/NovoRapid® insulin aspart (NN-Asp) in terms of efficacy, safety, and immunogenicity, in adults with type 1 or type 2 diabetes switching from different rapid-acting insulin analogs., Methods: This phase 3, randomized, open-label, multinational, 52-week study (GEMELLI 1) enrolled participants with type 1 or type 2 diabetes (n = 597). At randomization, participants transitioned from NovoLog/NovoRapid (n = 380) or Humalog®/Liprolog® (n = 217) to equivalent (1:1) doses (or a dose at the discretion of the investigator) of either SAR-Asp or NN-Asp (1:1 randomization). Participants were treated with multiple daily injections in combination with insulin glargine 100 U/mL (Lantus®). In this subgroup analysis, efficacy measures (change in hemoglobin A1c [HbA1c], insulin dose [total, basal and mealtime]), and safety outcomes (hypoglycemia incidence, adverse events, anti-insulin aspart antibodies) of SAR-Asp were compared with those of NN-Asp separately according to the participants' prestudy mealtime insulin., Results: At week 26 (primary efficacy endpoint), change in HbA1c was similar between SAR-Asp and NN-Asp in those participants pre-treated with NovoLog/NovoRapid (least squares [LS] mean difference - 0.04%, 95% confidence interval [CI] - 0.182 to 0.106%) or Humalog/Liprolog (LS mean difference - 0.15%, 95% CI - 0.336 to 0.043%) (P value for treatment by subgroup interaction = 0.36). This HbA1c response persisted over the 52 weeks of the study similarly for both treatments within each subgroup. In both subgroups, changes in insulin doses were similar between treatments over 26 weeks and 52 weeks, as were the incidences of severe or any hypoglycemia, adverse events (including hypersensitivity and injection site reactions), and anti-insulin aspart antibodies., Conclusions: Efficacy and safety (including immunogenicity) profiles of SAR-Asp are similar to those of NN-Asp over 52 weeks in adults with diabetes irrespective of prior type of mealtime insulin., Trial Registration: ClinicalTrials.gov identifier: NCT03211858.

Background: SAR341402 (SAR-Asp) is a biosimilar/follow-on of the originator insulin aspart-NovoLog ® /NovoRapid ® (NN-Asp). This study investigated whether the efficacy, safety, and immunogenicity findings for SAR-Asp versus NN-Asp, observed over 6 months in people with type 1 ( n  = 497) or type 2 diabetes ( n  = 100) treated with multiple daily injections in combination with insulin glargine (Lantus ® ), are maintained after 12 months. Materials and Methods: GEMELLI 1 was a multicenter, randomized, open-label, phase 3 study. Participants completing the initial 6-month treatment period continued on SAR-Asp or NN-Asp, as randomized, for a 6-month safety extension. Results: Of the 597 participants randomized, 264 out of 301 (87.7%) and 263 out of 296 (88.9%) assigned to SAR-Asp and NN-Asp, respectively, completed 12 months of treatment. Improved glycemic control was sustained at 12 months in both treatment groups, with similar least-squares mean reductions in glycated hemoglobin (HbA1c) from baseline (SAR-Asp: -0.25%; NN-Asp: -0.26%). Fasting plasma glucose and seven-point self-monitored plasma glucose profile changes, including postprandial glucose excursions, and changes in mealtime and basal insulin dosages were similar between groups. Safety and tolerability, including anti-insulin aspart antibodies (AIAs; incidence, prevalence, titers, cross-reactivity to human insulin), neutralizing antibodies (incidence, prevalence), hypoglycemia, and treatment-emergent adverse events (including hypersensitivity events and injection site reactions), were similar between groups. No relationship was observed between maximum individual AIA titers and change in HbA1c or insulin dose, hypoglycemia, or hypersensitivity reactions or between efficacy/safety measures and subgroups by presence or absence of treatment-emergent AIA. Conclusions: SAR-Asp and NN-Asp demonstrated similar efficacy and safety (including immunogenicity) in people with diabetes over 12 months of treatment.

Background: This study compared the efficacy, safety, and immunogenicity of insulin aspart biosimilar/follow-on biologic product SAR341402 (SAR-Asp) with originator insulin aspart-NovoLog ® /NovoRapid ® (NN-Asp) in people with type 1 diabetes (T1D) or type 2 diabetes (T2D) treated with multiple daily injections in combination with insulin glargine (Lantus ® ; Gla-100). Materials and Methods: This 6-month, randomized, open-label, phase 3 study (NCT03211858) enrolled 597 people with T1D ( n  = 497) or T2D ( n  = 100). Participants were randomized 1:1 to mealtime SAR-Asp ( n  = 301) or NN-Asp ( n  = 296) in combination with Gla-100. The primary objective was to demonstrate noninferiority (by 0.3% margin in the intent-to-treat population) of SAR-Asp versus NN-Asp in HbA1c change from baseline to week 26. Immunogenicity was also assessed in terms of anti-insulin aspart antibody (AIA) status (positive/negative) and titers during the study. Results: HbA1c was similarly improved in both treatment groups (SAR-Asp -0.38%; NN-Asp -0.30%); the least squares mean difference at week 26 for SAR-Asp minus NN-Asp was -0.08% (95% confidence interval: -0.192 to 0.039), thus meeting the criteria for noninferiority between SAR-Asp and NN-Asp and inverse noninferiority of NN-Asp versus SAR-Asp. Changes in fasting plasma glucose and seven-point self-monitored plasma glucose profile, including postprandial glucose excursions, and insulin dosages were similar in both groups at week 26. Safety and tolerability, including AIA responses (incidence, prevalence), hypoglycemia, and adverse events (including hypersensitivity events and injection site reactions), were similar between groups. Conclusions: SAR-Asp demonstrated effective glycemic control with a similar safety and immunogenicity profile to NN-Asp in people with diabetes treated for 26 weeks.

Background: SAR342434 (U100; SAR-Lis; insulin lispro) is a biosimilar/follow-on to insulin lispro (U100; Ly-Lis). Similar pharmacokinetics/pharmacodynamics between the two products has been demonstrated in a hyperinsulinemic euglycemic clamp study. The current study evaluated the safety of SAR-Lis and Ly-Lis when administered by continuous subcutaneous insulin infusion (CSII; insulin pumps)., Methods: This was a randomized, open-label, 2 × 4-week, two-arm crossover study in 27 patients with type 1 diabetes mellitus (NCT02603510). The main outcome was the incidence of infusion set occlusions (ISOs), defined as failure to correct hyperglycemia (plasma glucose ≥≥ 300 mg/dl) by 50 mg/dl within 60 minutes by insulin bolus via the pump. Secondary outcomes included intervals between infusion set changes, treatment-emergent adverse events (TEAEs) including infusion site, hypersensitivity reactions and hypoglycemic events, and safety., Results: The number of patients reporting at least one ISO was small: 6/25 patients on SAR-Lis reported 14 ISOs and 4/27 on Ly-Lis reported nine ISOs. The estimated difference in ISO risk for SAR-Lis versus Ly-Lis was 7.9% (95% CI, -1.90 to 17.73). Mean interval between infusion set changes for any reason was similar with SAR-Lis (3.09 days) and Ly-Lis (2.95 days). The event rate (events/patient-month) of any hypoglycemia was similar with SAR-Lis (7.15) and Ly-Lis (7.98), as was the percentage of patients who experienced any TEAE (12.0% and 14.8%)., Conclusion: Both SAR-Lis and Ly-Lis were well tolerated by patients using insulin pumps. The results do not suggest a clinically significant difference in the risk of ISO between SAR-Lis and Ly-Lis when used in CSII.

Background: SAR342434 (SAR-Lis) is a biosimilar (follow-on) of insulin lispro (Humalog ® ; Ly-Lis). Two randomized, controlled, open-label, parallel-group, phase 3 studies were conducted to compare the efficacy and safety of SAR-Lis and Ly-Lis, both in combination with insulin glargine (Lantus ® ). SORELLA 1 was a 12-month study in 507 people with type 1 diabetes mellitus (T1DM); SORELLA 2 was a 6-month study in 505 people with type 2 diabetes mellitus (T2DM). In this study, the impact of anti-insulin antibodies (AIA) to SAR-Lis and Ly-Lis on safety and glycemic control is reported., Methods: AIA were measured regularly throughout both studies at a centralized laboratory blinded to treatment groups using a drug-specific AIA assay. The AIA status (positive or negative), AIA titers, and cross-reactivity to human insulin, insulin glargine, and insulin glargine metabolite M1 were analyzed. The potential effect of AIA on safety, particularly as related to hypersensitivity reactions, hypoglycemia, and treatment-emergent adverse events, as well as on glycemic control (HbA 1c , insulin dose), was evaluated., Results: AIA positive status at baseline was similar for the two insulins, but higher in T1DM than in T2DM. In both studies, the percentage of people newly developing AIA in the two treatment groups, or having a ≥4-fold increase in AIA titers, did not differ. No relationship was observed between maximum individual AIA titers and change in HbA 1c or insulin dose, hypoglycemia, or hypersensitivity reactions or between efficacy/safety measures and subgroups by presence or absence of treatment-emergent AIA. Hypersensitivity events and events adjudicated as allergic reactions were few and did not differ between the two groups., Conclusion: Insulin lispro SAR342434 and the originator insulin lispro had a similar immunogenicity profile in people with T1DM or T2DM.

Background: SAR342434 (SAR-Lis) is a biosimilar (follow-on) of insulin lispro (U100; Humalog ® ; Ly-Lis). This study aimed to show similar efficacy, safety, and immunogenicity of SAR-Lis versus Ly-Lis in adult patients with type 2 diabetes mellitus (T2DM) treated with multiple daily injections, while using insulin glargine (GLA-100; Lantus ® ) as basal insulin., Methods: SORELLA 2 was a 6-month, randomized, open-label, Phase 3 study (NCT02294474). Insulin doses were adjusted to achieve fasting and 2-h postprandial glucose targets according to American Diabetes Association guidelines. Primary endpoint was the HbA 1c change from baseline to week 26 (tested for noninferiority of SAR-Lis vs. Ly-Lis with a margin of 0.3%). Secondary endpoints included fasting plasma glucose (FPG), seven-point self-monitored plasma glucose (SMPG) profiles, hypoglycemic events, treatment-emergent adverse events (TEAEs), and anti-insulin antibodies (AIA)., Results: A total of 505 patients were randomized (1:1) to multiple daily injections of SAR-Lis (n = 253) or Ly-Lis (n = 252) plus once-daily GLA-100. Least square (LS) mean (standard error) change in HbA 1c from baseline to week 26 was similar in both treatment groups (SAR-Lis, -0.92% [0.051] and Ly-Lis, -0.85% [0.051]). Noninferiority at prespecified 0.3% noninferiority margin was demonstrated (LS mean difference of SAR-Lis vs. Ly-Lis: -0.07% [95% CI: -0.215 to 0.067]) as was inverse noninferiority. Similar changes in FPG, seven-point SMPG profiles, including postprandial glucose excursions and mean glucose over 24 h, and insulin dosages were observed in the two groups. Hypoglycemia, TEAEs, and AIA (incidence and prevalence) did not differ between groups., Conclusions: Results from this controlled study in patients with T2DM also using GLA-100 support similar efficacy and safety (including immunogenicity) of SAR-Lis and Ly-Lis.

Background: SAR342434 is a biosimilar follow-on of insulin lispro-Humalog ® . This study aimed to show similar efficacy, safety, and immunogenicity of SAR342434 (SAR-Lis) versus insulin lispro-Humalog (Ly-Lis) in adult patients with type 1 diabetes (T1DM) treated with multiple daily injections while using basal insulin glargine (Lantus ® ; GLA-100)., Materials and Methods: SORELLA-1 was a randomized, open-label phase 3 study (NCT02273180). Patients completing the 6-month main study continued on SAR-Lis or Ly-Lis, as randomized, for a 6-month safety extension. Assessments included change in HbA 1c , fasting plasma glucose (FPG), seven-point self-monitored plasma glucose (SMPG) profiles, hypoglycemic events, treatment-emergent adverse events (TEAEs), and anti-insulin antibodies (AIAs)., Results: Five hundred seven patients were randomized (SAR-Lis n = 253; Ly-Lis n = 254). Least square (LS) mean (SEM) change in glycosylated hemoglobin (HbA1c) (baseline to week 26; primary endpoint) was similar in both treatment groups (SAR-Lis: -0.42% [0.051]; Ly-Lis: -0.47% [0.050]). Noninferiority at prespecified 0.3% noninferiority margin and inverse noninferiority were demonstrated (LS mean difference of SAR-Lis vs. Ly-Lis: 0.06% [95% confidence interval: -0.084 to 0.197]). At week 52 (end of extension period) versus week 26, a small HbA1c increase was observed in both groups. FPG and seven-point SMPG profile changes, including postprandial glucose excursions, were similar between groups. At week 52, similar changes in mean daily mealtime and basal insulin doses were observed. Hypoglycemia, TEAEs, and AIAs (incidence, prevalence) did not differ between groups., Conclusions: Results from this controlled study in patients with T1DM also using GLA-100 support similar efficacy and long-term safety (including immunogenicity) of SAR-Lis and Ly-Lis.

The objective of this study was to compare the efficacy and safety of insulin glargine, a long-acting insulin analog, with NPH insulin in children and adolescents with type 1 diabetes mellitus (T1DM). In a multicenter, open-label, randomized, 6-month study, 349 patients with TIDM, aged 5-16 years, received insulin glargine once daily or NPH insulin either once or twice daily, based on their prior treatment regimen. Although there was no significant difference between the NPH insulin and insulin glargine treatment groups with respect to baseline to endpoint change in HbA1c levels, fasting blood glucose (FBG) levels decreased significantly more in the insulin glargine group (-1.29 mmol/l) than in the NPH insulin group (-0.68 mmol/L, p = 0.02). The percentage of symptomatic hypoglycemic events was similar between groups; however, fewer patients in the insulin glargine group reported severe hypoglycemia (23% vs 29%) and severe nocturnal hypoglycemia (13% vs 18%), although these differences were not statistically significant (p = 0.22 and p = 0.19, respectively). Fewer serious adverse events occurred in the insulin glargine group than in the NPH insulin group (p < 0.02). A once-daily subcutaneous dose of insulin glargine provides effective glycemic control and is well tolerated in children and adolescents with T1DM.

Glimepiride is a new generation sulphonylurea being prudently characterized in more than 2000 NIDDM patients. It has a short onset of action and a long duration of action. The same pharmacodynamic effect as with traditional sulphonylureas is achieved with secretion of less insulin, suggesting a possible extrapancreatic action. Glimepiride is given once daily in doses from 1-8 mg/day. 100% absolute bioavailability and the absence of a food interaction guarantee highly reproducible pharmacokinetics. Glimepiride is a remarkably safe drug especially in NIDDM patients at high risk e.g. the renally impaired, elderly or physically very active person. Hypoglycemia is less frequent in the first weeks of treatment than with glibenclamide. Ongoing studies are investigating the possible beneficial clinical effect of its different binding behavior to the potassium channel, especially in the heart.
