Sansulin® Log-G is an insulin glargine biosimilar. For a biosimilar, its efficacy, safety, and immunogenicity should be compared head-to-head with its reference product in at least non-inferiority study. Immunogenicity assessment should always be done because it is influenced by so many factors, from nature of the drug substance until patient and disease related factors. Moreover its consequences also vary considerably, from clinically irrelevant to serious and life-threatening. Immunogenicity of a biosimilar should always be investigated in humans, since animal data are usually not predictive of the immune response in humans.~Since blinding of study participants is likely unfeasible, at least anti-drug antibodies should be determined in a blinded fashion. Since anti-insulin antibodies develop early, then 6 months duration of study is adequate.
This is an open-label randomised multicenter clinical study to investigate efficacy, safety, and immunogenicity of the drug products: Insulin Glargine biosimilar ® Log-G and its reference Lantus® in type 2 diabetes mellitus patients
