Brief summary

The purpose of this study is to evaluate the safety and drug detection of the dapivirine vaginal ring and oral Truvada in breastfeeding mother-infant pairs.

Detailed description

This study will evaluate the safety and drug detection of the dapivirine (DPV) vaginal ring (VR) and oral Truvada in breastfeeding mother-infant pairs. Mother-infant pairs will be randomly assigned to receive either the DPV VR or oral Truvada. Mothers randomized to the DPV VR will use the VR continuously for approximately one month (4 weeks), replacing the VR each month for approximately three months (12 weeks). Mothers using the Truvada tablet will take one tablet by mouth daily for approximately three months (12 weeks). Study visits will occur at Day 0, Weeks 1 and 2, and Months 1, 2, 3, and 3.5. Study visits may include behavioral assessments; product acceptability assessments; infant feeding assessments; physical examinations; blood, urine, and breast milk collection; and pelvic examination and specimen collection.

Inclusion criteria

Inclusion Criteria - Mother Participant mothers must meet all the following criteria to be eligible for inclusion in the study: * Age 18 years or older at Screening, as verified per site Standard Operating Procedures (SOPs). * At Enrollment, between 6 to 12 weeks postpartum (verified by birth records and/or similar supportive documentation and defined as between 42 - 84 days after delivery, inclusive). * By participant report at Screening and Enrollment, currently exclusively breastfeeding one infant and willing and able to continue exclusively breastfeeding that infant for the duration of their participation in the study. * Note: Exclusive breastfeeding will be defined as infant nutrition solely from breast milk, as determined by 7-day recall breastfeeding history. For the purposes of MTN-043, breastfeeding refers to all human milk feeding situations when an infant is fed with participant's own human milk whether the milk is received directly from the breast or as expressed milk. * Consistently using an effective method of contraception per participant report at Enrollment, and intending to continue use of an effective method for the duration of study participation. Effective methods include contraceptive implants, intrauterine device, injectable progestin, oral contraceptive pills, and surgical sterilization. * Able and willing to comply with all study requirements and complete all study procedures. * Able and willing to provide the following: * Written informed consent to be screened for and to take part in the study. * Written informed consent for the breastfed infant to be screened for and take part in the study. * Intention to stay within study catchment area for study duration and willingness to give adequate locator information, as defined in site SOPs. * At Screening and Enrollment, HIV-uninfected based on HIV testing performed by study staff (per algorithm in the study protocol). * At Screening and Enrollment, willing to be randomized at time of enrollment to either of the study products, and to continue study product use for at least 12 weeks. Inclusion Criteria - Infant Each mother eligible for MTN-043 will be asked to provide written informed consent for herself and her infant to participate in the study if the infant meets the following criteria: * At Screening and Enrollment, infant is exclusively breastfed. * Note: Exclusive breastfeeding will be defined as infant nutrition solely from breast milk, as determined by 7-day recall breastfeeding history. For the purposes of MTN-043, breastfeeding refers to all human milk feeding situations when an infant is fed with participant's own human milk whether the milk is received directly from the breast or as expressed milk. * At Screening and Enrollment, the infant is generally healthy, according to the judgment of the investigator of record (IoR)/designee. * At Enrollment, the infant is between the ages of 6 and 12 weeks postpartum (verified by birth records and/or similar supportive documentation with age defined as between 42 - 84 days after delivery, inclusive).

The Number of Mothers Non-adherent to Study Product for Each Month of Product Use by Study Product

The number and proportion of mother's visits with drug concentration indicative of non-adherence (no use) are reported by study month. Non-adherence is measured by residual drug in returned VRs for mothers assigned the DPV VR arm and by TFV-DP concentrations in dried blood spot specimens for mothers assigned the Truvada tablet arm. For mothers on the DPV VR arm, no use is defined as residual DPV concentration in the returned VRs \<= 0.9mg/month. For mothers on the Truvada arm, no use is defined as TFV-DP concentrations \< 16.6 fmol/punch. Only mother participants are included in this endpoint since infants did not directly use study product in this study.

Time frame: Measured through Month 3

Population: Only mother participants are included in this endpoint since infants did not directly use study product. The number of mothers analyzed includes mother participants with a returned/used vaginal ring that was successfully analyzed for residual drug concentration (evaluable) for Group A (DPV VR) and only those participants with an available and evaluable dried blood plot specimen for mothers in Group B (Truvada). Rings returned after the Month 3 Product Use End Visit (PUEV) are excluded.
