  • Estimating the cost of and willingness to pay for providing the dapivirine ring for HIV prevention in Kenya

    Open AccessPeter Stegman, Steven Forsythe et al.ARTICLEBMC Public Health2025

    This analysis revealed that costs are predominantly driven by commodities. Attempts to further reduce the cost of the commodities could significantly reduce the overall cost of PrEP ring service. Approximately half the women were willing to pay up to US$2 per month for the PrEP ring. Since the demand for the PrEP ring appears to be higher among current oral PrEP users compared to non-users, women who have initiated oral PrEP but who are unable or…

  • Acceptability of the dapivirine vaginal ring for HIV-1 prevention among women reporting engagement in transactional sex

    Erica N Browne, Kristine Torjesen et al.ARTICLEAIDS Care2024

    We assessed if acceptability of the dapivirine vaginal ring for HIV prevention differed among the subgroup of women who reported engaging in transactional sex prior to enrollment in MTN-020/ASPIRE (phase III trial in Malawi, South Africa, Uganda, and Zimbabwe, 2012-2015; n = 2629). Transactional sex was defined as receipt of money, goods, gifts, drugs, or shelter in exchange for sex in the past year. Dimensions of acceptability included: ease of …

  • Engaging HIV-prevention ambassadors to promote oral PrEP among adolescent girls and young women

    Open AccessMorgan Garcia, Definate Nhamo et al.ARTICLEAfrican Journal of AIDS Research2022

    The HIV Prevention Ambassador Training Package for Adolescent Girls and Young Women was created in collaboration with adolescent girls and young women (AGYW) to improve skills, knowledge, and attitudes about oral pre-exposure prophylaxis (PrEP) among peer "ambassadors". It was field tested with 17 ambassadors in Mazowe District, Zimbabwe and changes in ambassadors' knowledge and attitudes about oral PrEP, as well as changes in oral PrEP uptake am…

  • Impact and experience of participant engagement activities in supporting dapivirine ring use among participants enrolled in the phase III MTN-020/Aspire study

    Open AccessMorgan Garcia, Ellen Luecke et al.ARTICLEBMC Public Health2021

    Our analysis supports the growing body of work illustrating the importance of meaningfully engaging research participants to achieve study success and aligns with other analyses of adherence support efforts during ASPIRE. While causation between PEA attendance and product use cannot be established, residual drug levels in returned rings strongly correlated with participant attendance at PEAs, and the benefits of incorporating PEAs should be consi…

  • Acceptability of the Dapivirine Vaginal Ring for HIV-1 Prevention and Association with Adherence in a Phase III Trial

    Open AccessAshley Mayo, Erica N Browne et al.ARTICLEAIDS and Behavior2021

    We evaluated the acceptability of the 25 mg dapivirine vaginal ring (DVR) as an HIV prevention intervention and its influence on DVR adherence in the MTN-020/ASPIRE phase III trial. Acceptability measures were captured using ACASI at month 3 and end of product use (median 24 months, IQR 15-30). Monthly returned rings were classified as nonadherent if dapivirine release rate was ≤ 0.9 mg/month. Associations between acceptability measures and nonad…

  • Efficiency in PrEP Delivery

    Open AccessCollin Mangenah, Definate Nhamo et al.ARTICLEAIDS and Behavior2021

    Although oral PrEP is highly effective at preventing HIV acquisition, optimizing continuation among beneficiaries is challenging in many settings. We estimated the costs of delivering oral PrEP to populations at risk of HIV in seven clinics in Zimbabwe. Full annual economic costs of oral PrEP initiations and continuation visits were estimated from the providers' perspective for a six-clinic NGO network and one government SGBV clinic in Zimbabwe (…

  • Use of a Vaginal Ring Containing Dapivirine for HIV-1 Prevention in Women

    Jared M Baeten, Thesla Palanee‐phillip et al.ARTICLENew England Journal of Medicine2016

    BACKGROUND: Antiretroviral medications that are used as prophylaxis can prevent acquisition of human immunodeficiency virus type 1 (HIV-1) infection. However, in clinical trials among African women, the incidence of HIV-1 infection was not reduced, probably because of low adherence. Longer-acting methods of drug delivery, such as vaginal rings, may simplify use of antiretroviral medications and provide HIV-1 protection. METHODS: We conducted a ph…
