Bioequivalence Study of Two Albiglutide Drug Products in Healthy Adult Subjects

GlaxoSmithKline59 enrolled

Overview

Albiglutide (Alb) is a novel analogue of glucagon-like peptide-1 (GLP-1) has been developed and approved for the treatment of type 2 diabetes mellitus. Currently, lyophilized albiglutide and the diluent are provided in a dual chamber Cartridge (DCC) single-dose pen injector, requiring reconstitution prior to use. A liquid formulation of albiglutide will enable the use of a liquid product in a ready-to-use single dose auto-injector. To support the development of the liquid auto-injector product, this healthy volunteer bioequivalence study will be conducted to compare the liquid drug product to the currently available lyophilized product. This is Phase I, randomized, double-blind, double dummy, single-dose, 2-period crossover study in healthy volunteers. This study will compare the pharmacokinetics and safety of the albiglutide 50 mg liquid drug product with the albiglutide 50 mg commercial lyophilized drug product.
