740-P: Proposed Biosimilar Gan & Lee Insulin Glargine (GL-GLA) Shows Pharmacokinetic (PK) and Pharmacodynamic (PD) Bioequivalence (BE) to U.S.- and EU-Licensed Insulin Glargine (IG)

Abstract

This randomized, double-blind, three-way crossover trial (NCT04236895) compared the PK and PD properties of GL-GLA, a proposed biosimilar IG by Gan & Lee, US- and EU-licensed Lantus® (US-IG and EU-IG) in 114 male subjects with type 1 diabetes (mean±SD age 42±8 years, BMI 25.8±2.0 kg/m²). Each subject received a single 0.5 U/kg dose of either GL-GLA, EU-IG, or US-IG in each of the 3 euglycemic glucose clamp periods (ClampArt, clamp level 100 mg/dl, clamp duration 30h post-dose). PK is presented as concentrations of the mainly absorbed IG metabolite M1. GL-GLA and comparator insulins showed superimposable profiles for PK and glucose infusion rates (GIR, Figure). PK BE was demonstrated between GL-GLA and the comparator insulins as the point estimates for measured metabolite M1 were close to 100% and 90% CIs were well contained within the pre-defined similarity margins of 80-125% (Figure). Likewise, the primary PD endpoints met BE-criteria as did secondary PK/PD-endpoints including AUCM1.0-12h, AUCM1.12-24h, AUCGIR.0-12h, and AUCGIR.12‑24h. All insulins were well tolerated with similar adverse event rates (19% [GL-GLA]; 26% [US-IG]; 21% [EU-IG]) and only few events of injection site reactions per insulin. In conclusion, GL-GLA demonstrated both PK- and PD-bioequivalence to US- and EU-licensed insulin glargine formulations. Disclosure T.
