Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase I single-center, two-arm, open-label, randomized study in healthy HIV-negative women to evaluate the pharmacokinetics, safety, and bleeding patterns associated with 90-day use of matrix vaginal rings containing 200 mg Dapivirine and 320 mg Levonorgestrel.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This 26 week study will be conducted at one site. The site will enroll 24 subjects. Subjects will be randomized to 1 of 2 treatment regimens:

Regimen A: vaginal ring used continuously for approximately 90 days Regimen B: vaginal ring used cyclically for approximately 90 days: used for \~28 days, then removed,washed and stored for 2 days. The same ring will be used for 2 additional cycles in a similar fashion.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Assigned female sex at birth Note: Participants who are female at birth, who now identify as male, will not be excluded so long as they are not currently or have not been on female-to-male transition therapy 90 days prior to Enrollment.
2. Age 18 through 45 years (inclusive) at Screening, verified per site SOPs
3. Able and willing to provide written informed consent to be screened for and enrolled in MTN-044/IPM 053/CCN019

8. Not at risk for pregnancy, defined as consistently using an effective, non-hormonal method of contraception per participant report at Enrollment, and intending to continue use of an effective, non-hormonal method for the duration of study participation. Effective methods include:

1. Non-hormonal (e.g. copper) intrauterine device (IUD) inserted at least 28 days prior to Enrollment
2. Consistent and correct male condom use
3. Sterilization (of participant or partner, as defined in site SOPs)
4. Having sex exclusively with individuals assigned female sex at birth

11. Per participant report at Screening, current regular menstrual cycles of approximately 21 to 35 days in duration with no reported intermenstrual bleeding
12. Intact uterus with at least one ovary
13. Per participant report at Screening and Enrollment, states a willingness to refrain from inserting any non-study vaginal products or objects into the vagina including, but not limited to spermicides, female condoms, diaphragms, other intravaginal rings, vaginal medications, menstrual cups, cervical caps (or any other vaginally applied barrier method), vaginal douches, lubricants and moisturizers, for the 24 hours preceding the Enrollment Visit through completion of Visit 15.
14.
