Trial overview
Official title: A Phase 1, Randomized, Single Blind Study to Evaluate the Pharmacokinetics, Pharmacodynamics, and Safety of an Oral Contraceptive Containing Norethindrone and Ethinyl Estradiol When Co-administered with GSK1322322 in Healthy Adult Women of Childbearing Age Who are of Non-Childbearing Potential Due to Surgical Sterilization or IUD Placement (PDF112163)
Trial description: This study is being conducted to confirm that GSK1322322 has no negative impact on hormone levels and contraceptive efficacy when co-administered with a frequently prescribed oral contraceptive thereby to facilitate the use of GSK1322322 in women of child-bearing potential receiving oral contraceptive (OC) pre-infection. This study is designed to investigate steady-state plasma ethinyl estradiol (EE) and norethindrone (NE) pharmacokinetic (PK) following administration of Ortho-Novum (EE/NE) 1 tablet every 24 hours (q24h) fed with and without GSK1322322 1500 milligram (mg) q12h fed. Each subject will participate in the study for approximately 12 weeks: a 30 day screening period, 4-week run-in period, three 7 day treatment periods, and a 3-5 day follow-up period. The study is planned to enroll approximately 24 subjects (18 active/6 placebo).

Primary outcomes:
Composite of PK parameters of EE/NE to compare the steady state plasma PK. If data permit, after EE/NE alone for 7 days and after EE/NE with GSK1322322 for 7 days.
Timeframe: Plasma PK samples will be collected at pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 hours on Day 7, 14 and 21 of both run-in phase and on treatment phase.
Secondary outcomes:

Timeframe: Plasma PK samples will be collected at pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8 and 12 hours post morning dose on day 7, 14, and 21 of treatment phase.

Accepts healthy volunteers
Yes
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator feels that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Non smoking female (of childbearing age), between 18 and 45 years of age inclusive, at the time of signing the informed consent.
- Pregnant females as determined by positive human chorionic gonadotropin (hCG) test at screening or prior to dosing.
- History of any condition that would contraindicate Ortho-Novum administration (including hypertension, stroke, ischemic heart disease, venous thromboembolism or family history of thromboembolism, known factor V Leiden mutation or other gene mutations associated with increased risk of thromboembolism, migraine headaches, carcinoma of the breast, liver or endometrium, gallbladder disease, history of undiagnosed abnormal uterine bleeding, etc.
Inclusion and exclusion criteria
Inclusion criteria:

A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator feels that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Non smoking female (of childbearing age), between 18 and 45 years of age inclusive, at the time of signing the informed consent.
