This study is a two-period, double-blind study in healthy adult female subjects. Each subject will participate in an oral contraceptive Run-in period prior to the treatment periods. The length of the Run-in Period will be 28 days or longer, depending on the timing of the subject's menstrual cycle and on whether the subject is taking an OC. Each subject will participate in this run-in period (if needed), followed by two treatment periods. Treatment Periods 1 and 2 must be conducted successively. Subjects will be randomized in a cross-over fashion to either YASMIN with GSK2248761 or Placebo for 10 days and switch GSK2248761 or placebo for another 10 days. Subjects will return to the study center for final follow up evaluations 7 - 14 days after the final dose of study medication.

Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • AST, ALT, alkaline phosphatase and bilirubin less than or equal to 1.5xULN (isolated bilirubin greater than 1.5xUpper limit of normal is acceptable if bilirubin is fractionated and direct bilirubin less than 35%).
  • Healthy female subjects, 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 and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Female, between 18 and 40 years of age inclusive, at the time of signing the informed consent.
  • Women of childbearing potential must use the following appropriate contraceptive methods: oral contraceptive YASMIN in combination with complete abstinence from intercourse for at least 14 days prior to the first dose of investigational product (Day 1 of Period 1), throughout the study, and for the subsequent post study monitoring or; YASMIN in combination with a barrier method plus a spermicide (e.g., condom or diaphragm with spermicidal foam/gel/cream/ suppository for at least 14 days prior to the first dose of investigational product [Day 1 of Period 1]) throughout the study, and for the subsequent post study monitoring or; Sterilization (vasectomy) of male partner prior to commencement of female subject's last normal menstrual period prior to administration of study drug, and the male partner is the sole partner for that female subject;
  • The subject's Body Mass Index is 19 to 30 killograms/millimeters squared and body weight greater than or equal to 50 kilograms (110 pounds) and less than 114 kilograms (less than 250 pounds);
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form;
  • Single QTc, QTcB or QTcF less than 450 msec; or QTc less than 480 msec in subjects with Bundle Branch Block

Exclusion Criteria:

  • A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • A positive pre-study drug/alcohol screen.
  • A positive test for HIV antibody.
  • History of regular alcohol consumption within 6 months of the study defined as: an average weekly intake of >7 drinks for females.
  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
  • Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
  • Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
  • History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mililiters within a 56 day period.
  • Women of childbearing potential who are unwilling or unable to use an appropriate method of contraception from at least 14 days prior to the first dose of investigational product until completion of the follow-up visit;
