Trial overview
Official title: An open-label study to evaluate the pharmacokinetics of an oral contraceptive containing Norethindrone and Ethinyl Estradiol when co-administered with GSK716155 in healthy adult female subjects
Trial description: 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.
Primary purpose:
Other
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Non-randomized
Primary outcomes:
AUC0-24 of norethindrone and ethinyl estradiol after OC alone in Period 1 and after OC with albiglutide in Period 2.
Timeframe: Day 21
Secondary outcomes:
Cmax, Cmin, tmax, and t½ of norethindrone and ethinyl estradiol after OC alone on Day 21 of Period 1 and after OC with albiglutide on Day 21 of Period 2.
Timeframe: Day 21 of each period.
Predose serum levels of LH and FSH after OC alone and after OC with albiglutide.
Timeframe: Days 1 and 11 through 14 of each period.
Predose serum levels of progesterone after OC alone and after OC with albiglutide.
Timeframe: Day 21 of each period.
