Brief Summary:
The purpose of the study is to examine the effects of two contraceptive methods and the menstrual cycle on the pharmacokinetics, pharmacodynamics of tenofovir 1% gel and the effect of the contraceptive methods on markers of mucosal safety.
Detailed Description:
Each woman will be seen in 6 visits and will be contacted by two scheduled follow-up telephone calls/visits. Volunteers will be consented at Visit 1 and undergo procedures to assess whether they are eligible to continue in the study. At Visit 2 (cycle days 20-25), after it has been confirmed that the participant meets all of the inclusion criteria and none of the exclusion criteria, genital samples will be taken and she will be given 2 applicators of tenofovir 1% gel to insert two hours apart. She will be instructed to return for Visit 3, approximately 3 or 11 hours after insertion of the second gel, as determined by randomization. The participant will retain this sampling assignment throughout the study.
At Visit 3 (cycle days 20-25), blood and genital samples will be collected. The participant will again be given 2 applicators of tenofovir 1% gel to insert two hours apart. She will be instructed to return approximately 3 or 11 hours after insertion of the second gel for Visit 4 (cycle days 5-10) and blood and genital samples will be taken. The participant will then start the contraceptive method that she has chosen from the two methods being evaluated in the study.
Each participant will be contacted about 4-5 weeks after Visit 4 to confirm the next visit date (Visit 5).
Visit 5 will take place about 6 weeks after starting contraception and will not have an associated gel use. Follow-up genital samples will be collected at Visit 5. The participant will be given 2 applicators of tenofovir 1% gel to insert two hours apart prior to Visit 6.
Visit 6 will take place about 10 weeks after starting contraception. Follow-up blood and genital samples will be collected approximately 3 or 11 hours after insertion of the second gel.
Each participant also will have a follow-up call or visit approximately 1-2 weeks after Visit 6 to confirm that there have been no adverse experiences. If necessary, she may be seen in an unscheduled visit for follow-up. She will then be exited from the study.
At Visit 3 (cycle days 20-25), blood and genital samples will be collected. The participant will again be given 2 applicators of tenofovir 1% gel to insert two hours apart.
