Who can join

Age: 18 and older, up to 49. Sex: female. Healthy volunteers: accepted.

You may qualify if…

• Healthy pre-menopausal female subjects between the ages of 18-49, inclusive, with an intact uterus and cervix. (Healthy is defined as no irregular menstrual cycles or clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG and clinical laboratory tests)
• All subjects must have an estimated calculated creatinine clearance (eCcr) of at least 80 mL/min by the Cockcroft-Gault formula where: eCcr (female) in mL/min = [(140 - age in years) x (weight in kg) x 0.85] / (72x serum creatinine in mg/dL).
• All subjects must have a negative serum pregnancy test at screening and negative urine pregnancy tests on days of dose administration and should be using at least one of the following methods of contraception from the screening visit through 72 hours prior to first outpatient visit (at which time the women will be asked to remain abstinent until after their follow-up visit)
• Systemic hormonal contraceptive (oral, depot, transdermal or implant)
• Intrauterine device placed at least 1 month prior to study enrollment
• Bilateral tubal ligation (Sterilization)
• Vasectomized male partners
• Condom + Spermicide
• Unless engaged in sexual activity with female only sex partners or abstinent for at least 3 months prior with no intention of becoming sexually active during the study period. Any history of recent or present concomitant male sex partners will be addressed and ruled out in the context of screening participants for eligibility for the protocol
• Body Mass Index (BMI) of approximately 18 to 34 kg/m2; and a total body weight > 50 kg (110 lbs).
• Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the trial.
• Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
• Subject must have documentation of a normal pap smear within 36 months of the screening visit, no procedures for abnormal cervical/vaginal pathology in the last six months, at least one prior gynecological visit as part of subject's routine medical history. If subjects have had a gynecological exam but no history of Pap smear, a Pap smear will be completed at screening and paid for by the study.
• Subject must be willing to abstain from sexual intercourse, douching, and all intravaginal objects and products for at least 72 hours prior to first study visit until study completion.
• Subject must be HIV-1 and Hepatitis B surface antigen negative as documented on screening labs.
• Subject must not be actively involved in the conception process.
• Subject must be able to swallow pills and have no allergies to any component of the study products.

You may not qualify if…

• Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including documented drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
• Subjects with a history of hysterectomy, or other clinically significant surgery of the female genital tract.
• Subjects who are pregnant, possibly pregnant or lactating
• Subjects with a presence of vaginal discharge or genital bleeding at screening
• History of febrile illness within five days prior to medication dosing.
• Any condition possibly affecting drug absorption (eg, gastrectomy).
• A positive urine drug screen.
• A positive result for HIV.
• Active Hepatitis B infection as determined by positive Hepatitis B surface antigen (HBsAg) or Hepatitis B core antibody (HBcAb) tests (in the absence of HBsAb).
• Active Hepatitis C (HCV) infection as defined by positive HCV Ab (determined by multi-antigen EIA) and detectable Hepatitis C RNA.
• A positive test for syphilis, gonorrhea, Chlamydia, or trichomonas at screening.
• Any laboratory chemistry or hematology result Grade 2 or greater according to the Division of Allergy and Infectious Disease (DAIDS) Laboratory Grading Tables
• Treatment with an investigational drug within 4 months preceding the first dose of trial medication.
• History of regular alcohol consumption exceeding 14 drinks (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of spirits) per week.
• Use of prescription or nonprescription drugs, vitamins, and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of trial medication and unable to avoid use during the inpatient pharmacokinetic visit. As an exception, systemic hormonal methods of contraception can be continued.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• Allergy to lidocaine or Monsel's solution.
• Allergy to latex.
• Abnormal pap smear in the past 12 months
• Any degree of ectopy or abnormality evident during the pelvic exam at screening.
• Any condition which, in the opinion of the investigator, is likely to interfere with follow-up or ability to take the study medication appropriately.
• Unwilling or unable to comply with the following dietary and concomitant drug restrictions in regard to study drug administration as outlined in the study procedures and prohibited medications sections.
• Subjects will not be allowed to eat or drink grapefruit containing products from 7 days prior to the first dose of trial medication until after collection of biopsy sample.
• Must refrain from taking any prescription, non-prescription, herbal, vitamin or dietary supplement within at least 7 days of the study visit through completion of the study without discussing with the study staff.
