A Study to Assess the Relative Bioavailability of Different Formulations of GSK2018682, a Sphingosine-1-phosphate Receptor Subtype 1 Agonist, in Healthy Volunteers.

Summary

GSK2018682 is a potent and selective agonist for the sphingosine-1- phosphate receptor subtype 1 (S1P1) with the potential to be an effective treatment for multiple sclerosis (MS). The immunomodulatory properties of GSK2018682 are related to functional antagonism of S1P1 on lymphocytes, resulting in sequestration of lymphocytes within the lymphoid organs, rendering them incapable of migrating to sites of inflammation and leading to lymphopenia. Orally administered GSK2018682 is very effective in murine experimental autoimmune encephalomyelitis (EAE), an animal model of human MS. This study will assess the relative bioavailability of different oral formulations of GSK2018682 in healthy volunteers. A tablet formulation is desired for progression into future clinical safety and efficacy studies as the current capsule formulation is not suited to large scale manufacture. The information obtained in this study will help to establish the optimal dosing form for future studies, and also determine the effect of food on the pharmacokinetics of GSK2018682.
