Safety, Immunogenicity, and Glycemic Control of Insulin Aspart Biosimilar SAR341402 Versus Originator Insulin Aspart in People with Diabetes Also Using Insulin Glargine: 12-Month Results from the GEMELLI 1 Trial.

ABSTRACT: 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.

Project description:IntroductionThe 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.MethodsThis 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.ResultsAt 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.ConclusionsEfficacy 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 registrationClinicalTrials.gov identifier: NCT03211858.

Project description:Background: This study investigated the effectiveness and safety of switching from Basalin® to Lantus® in Chinese patients with diabetes mellitus (DM). Methods: A retrospective chart review conducted using the electronic medical records of patients hospitalized at the Qingdao Endocrine and Diabetes Hospital from 2005 to 2016. All patients were diagnosed with DM and underwent switching of insulin from Basalin to Lantus during hospitalization. Data collected included fasting (FBG), pre- and post-prandial whole blood glucose, insulin dose, reasons for insulin switching and hypoglycemia. Four study time points were defined as: hospital admission, Basalin initiation, insulin switching (date of final dose of Basalin), and hospital discharge. Blood glucose measurements were imputed as the values recorded closest to the dates of these four time points for each patient. Results: Data from 73 patients (70 patients with type 2 diabetes, 2 with type 1, and 1 undisclosed) were analyzed. At admission, mean glycated hemoglobin (HbA1c) and FBG were 8.9% (SD=1.75) and 9.98 (3.22) mmol/L, respectively. Between Basalin initiation and insulin switch, mean FBG decreased from 9.68 mmol/L to 8.03 mmol/L (p<0.0001), over a mean 10.8 (SD=6.85) days of Basalin treatment, and reduced further to 7.30 mmol/L at discharge (p=0.0116) following a mean 6.6 (7.36) days of Lantus. The final doses of Basalin and Lantus were similar (0.23 vs. 0.24 IU/kg/day; p=0.2409). Furthermore, reductions in pre- and post-prandial blood glucose were also observed between Basalin initiation, insulin switch and hospital discharge. The incidence of confirmed hypoglycemia was low during Basalin (2 [2.4%]) and Lantus (1 [1.2%]) treatment, with no cases of severe hypoglycemia. Conclusion: In this study population, switching from Basalin to Lantus was associated with further reductions in blood glucose, although the dose of insulin glargine did not increase. Further studies are required to verify these findings and determine the reason for this phenomenon.
