Detaljeret beskrivelse

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. Post TFV gel and estradiol cream blood and genital samples will be taken (visit 6/6a).

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Ingen indgriben: Baseline
Premenopausal women will undergo baseline sampling in each the follicular and luteal phase. Postmenopausal women will undergo baseline sampling one time.
Eksperimentel: 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.

Eksperimentel: 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
Eksperimentel: TFV 1% gel and estradiol cream
Postmenopausal women only: 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. In addition, participants will one gram of estradiol cream into the vagina every other night.
