TOUJEO SOLOSTAR (insulin glargine,human recombinant analog)


Drug overview for TOUJEO SOLOSTAR (insulin glargine,human recombinant analog):

Generic name: INSULIN GLARGINE,HUMAN RECOMBINANT ANALOG (IN-su-lin GLAR-jeen)
Drug class: Intermediate-, Long-acting, and Combination Insulins
Therapeutic class: Endocrine

Insulin glargine, insulin glargine-aglr, and insulin glargine-yfgn are biosynthetic (rDNA origin), long-acting human insulin analogs. Insulin glargine (Lantus(R) ) and insulin glargine (Basaglar(R) ) are structurally and pharmacologically similar drugs that contain a related drug substance. Basaglar(R) was licensed by FDA through an abbreviated approval pathway (505(b)(2)) that relied in part on FDA's finding of safety and effectiveness for Lantus(R).

Comparative studies found no substantial differences between the pharmacokinetics, immunogenicity, or toxicity of Lantus(R) and Basaglar(R). Although Basaglar(R) is highly similar to Lantus(R) in terms of composition, strength, presentation, structure, and physicochemical and biological properties, it was not approved as a biosimilar or an interchangeable biologic product. At the time of the approval, insulin was classified by FDA as a chemical, not a biologic product, and there was no biologic reference product for insulin glargine; thus, biosimilarity to insulin glargine could not be established.

Instead, Basaglar(R) was referred to as a ''follow-on'' insulin glargine preparation; FDA determined that there was no need to use a different nonproprietary name (insulin glargine) for Basaglar(R) at that time. Subsequently, the classification of insulin was changed to a biologic product, and Basaglar(R) was included as a "rollover" drug product under this definition; however, Basaglar(R) is still not considered a biosimilar or interchangeable with Lantus(R). Insulin glargine-aglr (Rezvoglar(R)) and insulin glargine-yfgn (Semglee(R)) are biosimilar to insulin glargine (Lantus(R)).

FDA defines a biosimilar as a biological product that is highly similar to an FDA-licensed reference biological with the exception of minor differences in clinically inactive components and for which there are no clinically meaningful differences in safety, purity, or potency. The claim of biosimilarity is based on a totality-of-evidence approach, which includes consideration of data from analytical, animal, and clinical studies (e.g., human pharmacokinetic and pharmacodynamic studies, clinical immunogenicity assessment, additional comparative clinical studies). Therefore, biosimilarity may be established even when there are formulation or minor structural differences as long as these differences are not clinically meaningful.

Biosimilars are approved through an abbreviated licensure pathway that establishes biosimilarity between the proposed biological and the reference biological but does not independently establish safety and effectiveness of the proposed biological. In order to be considered an interchangeable biosimilar, a biological product must meet additional requirements beyond demonstrating biosimilarity to its reference product; these requirements include demonstrating that the biological product can be expected to produce the same clinical results as the reference product in any given patient and, for a biological product that is administered more than once to an individual, the risk in terms of safety or diminished efficacy of alternating or switching between use of the biological product and the reference product is no greater than the risk of using the reference product without such alteration or switch. Biosimilar products that are interchangeable can be substituted for the reference product without the intervention of the healthcare provider who prescribed the reference product.

Both insulin glargine-aglr (Rezvoglar(R)) and insulin glargine-yfgn (Semglee(R)) are designated as interchangeable with insulin glargine (Lantus(R)). In this monograph, unless otherwise stated, the term "insulin glargine products" refers to insulin glargine (the reference drug) and its biosimilars (insulin glargine-aglr and insulin glargine-yfgn).

Insulin glargine is commercially available as Lantus(R) (100 units/mL), Basaglar(R) (100 units/mL), and a concentrated preparation (Toujeo(R); 300 units/mL). Two insulin glargine biosimilars are currently available. Biosimilarity of these products has been demonstrated for the indications described in Table 1.

Biosimilarity to originator insulin glargine is additionally supported by comparative clinical studies in patients with type 1 and type 2 diabetes mellitus. Table 1.
