Influence of Reproductive Cycle and Menopause on HIV-1 Infection and TFV Gel Activity
Influence of Female Reproductive Cycle and Menopause on Cervicovaginal Tissue Susceptibility to HIV-1 Infections and Tenofovir 1% Gel Activity
調査の概要
詳細な説明
Premenopausal women: Baseline blood and genital samples will be taken in the follicular and luteal phase (visits 2 and 3). The participant will be given TFV gel and instructed to insert two doses, separated by 2 hours, and return to the clinic 3 hours after the second insertion for blood and genital samples (visits 4/4a and 5/5a).
Postmenopausal women: Premenopausal women: Baseline blood and genital samples will be taken (visit 2). The participant will be given TFV gel and instructed to insert two doses, separated by 2 hours, and return to the clinic 3 hours after the second insertion for blood and genital samples (visit 3/3a). Estradiol cream will be distributed at visit 4. Post estradiol blood and genital samples will be taken at Visit 5. The participant will given TFV gel and instructed to insert 2 doses as before, while continuing to use the estradiol cream.

|---|---|
|
介入なし：Baseline
Premenopausal women will undergo baseline sampling in each the follicular and luteal phase.
Postmenopausal women will undergo baseline sampling one time.

実験的：TFV 1% Gel
Participants will vaginally insert 1 applicator of TFV gel followed by a 2nd applicator 2 hours later. Each applicator contains 4.4 gm of TFV 1% gel. Premenopausal women will undergo sampling after TFV gel use in each the follicular and luteal phase. Postmenopausal women will undergo sampling after TFV gel use one time. |

実験的：Estradiol Vaginal Cream
Post menopausal women only: Participants will insert 2 grams of estradiol cream into the vagina every night for 14 days and then one gram of estradiol cream into the vagina every other night
