Secondary Outcomes (2)

• Dapivirine concentrations in vaginal fluid

  28 days

• Clotrimazole concentrations in vaginal fluid

Upon pelvic examination at the time of enrolment, the cervix and vagina appear normal as determined by the Investigator/Physician Asymptomatic for genital infections at the time of enrolment (if a woman is diagnosed with any treatable STI, either clinically or by laboratory test at the time of screening, she must complete treatment prior to enrolment) 8. Willing to refrain from the use of topical vaginal medications, vaginal products or objects, including female condoms, tampons, cotton wool, rags, diaphragms, cervical caps (or any other vaginal barrier method), douches, lubricants, vibrators/dildos, and drying agents for 14 days prior to enrolment and for the duration of the trial 9. Documentation of no abnormality on cervical cytology, including grossly bloody smear, within 90 days prior to screening 10. Willing to refrain from participation in any other research trial for the duration of this trial 11. Willing to provide adequate locator information for trial retention purposes and be reachable per local standard procedures, e.g. by home visit or telephone, or via family or close neighbour contacts (confidentiality to be maintained) 12. Willing to agree to abstain for a total of 2 days (48 hours) prior to each trial visit from: Penile-vaginal intercourse Oral contact with her genitalia 13. Hepatitis B and C negative at the time of screening

You may not qualify if:

• Participants who have any of the following criteria are NOT eligible to enrol in the trial:
• Currently pregnant or had their last pregnancy outcome within 3 months prior to screening
• Currently breast-feeding
• Currently or within 2 months of participation in any other clinical research trial involving investigational or marketed products prior to screening
• Untreated symptomatic urogenital infections, e.g. urinary tract or other STIs, or other gynaecological conditions such as vaginal itching, pain, or discharge within 14 days prior to enrolment
• History of significant urogenital or uterine prolapse, undiagnosed vaginal bleeding, urethral obstruction, incontinence, urge incontinence or an anatomical variation that will not allow placement or retention of the ring
• Current vulvar or vaginal symptoms/abnormalities that could influence the trial results
• Cervical cytology at screening that requires cryotherapy, biopsy, treatment (other than for infection), or further evaluation
• Symptomatic genital herpes simplex virus (HSV) infection or a history of genital herpetic infection
• Any Grade 2, 3 or 4 haematology, biochemistry or urinalysis laboratory abnormality at baseline (screening) according to the Division of Acquired Immunodeficiency Syndrome (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events; Addendum 1 Female Genital Grading Table for Use in Microbicide Studies
• Unexplained, abnormal bleeding per vagina during or following vaginal intercourse, or gynaecologic surgery within 90 days prior to enrolment
