About

This study will be an open-label study to evaluate the effect of albiglutide on the pharmacokinetics and pharmacodynamics of a standard oral contraceptive regimen (Brevicon). The primary objective of this study is to demonstrate the lack of effect of albiglutide doses on the pharmacokinetics of norethindrone and ethinyl estradiol in healthy female subjects.
