Abstract

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 HbA1c, 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.
