    Acceptability and use of a dapivirine vaginal ring in a phase III trial
    (AIDS (London, England), 2017) Montgomery, Elizabeth T.; Straten, Ariane van der; Chitukuta, Miria; Reddy, Krishnaveni; Woeber, Kubashni; Atujuna, Millicent; Bekker, Linda-Gail; Etima, Juliane; Nakyanzi, Teopista; Mayo, Ashley J.; Katz, Ariana; Laborde, Nicole; Grossman, Cynthia I.; Soto-Torres, Lydia; Palanee-Phillips, Thesla; Baeten, Jared M.
    The MTN-020/ASPIRE trial evaluated the safety and effectiveness of the dapivirine vaginal ring for prevention of HIV-1 infection among African women. A nested qualitative component was conducted at six of 15 study sites in Uganda, Malawi, Zimbabwe and South Africa to evaluate acceptability of and adherence to the ring. Method—Qualitative study participants (n = 214) were interviewed with one of three modalities: single in-depth interview, up to three serial interviews or an exit Focus Group Discussion. Using semistructured guides administered in local languages, 280 interviews were audio-recorded, transcribed, translated, coded and analyzed. Results—We identified three key findings: first, despite initial fears about the ring's appearance and potential side effects, participants grew to like it and developed a sense of ownership of the ring once they had used it. Second, uptake and sustained adherence challenges were generally overcome with staff and peer support. Participants developed gradual familiarity with ring use through trial progression, and most reported that it was easy to use and integrate into their lives. Using the ring in ASPIRE was akin to joining a team and contributing to a broader, communal good. Third, the actual or perceived dynamics of participants' male partner relationship(s) were the most consistently described influence (which ranged from positive to negative) on participants' acceptability and use of the ring. Conclusion—It is critical that demonstration projects address challenges during the early adoption stages of ring diffusion to help achieve its potential public health impact as an effective, long-acting, female-initiated HIV prevention option addressing women's disproportionate HIV burden.

    Ask the Way From Those Who Have Walked It Before – Grandmothers’ Roles in Health-related Decision Making and HIV Pre-exposure Prophylaxis (PrEP) Use Among Pregnant and Breastfeeding Women in Africa
    (Research Square, 2021) Reddy, Krishnaveni; Kemigisha, Doreen; Chitukuta, Miria; Dadabhai, Sufia; Mathebula, Florence; Tenza, Siyanda; Palanee-Phillips, Thesla; Ryan, Julia; van der Straten, Ariane; Musara, Petina; Macagna, Nicole; Ryan, Julia
    HIV acquisition among pregnant and breastfeeding women in sub-Saharan Africa (SSA) and vertical transmission rates remain high despite established strategies for HIV prevention. Methods: We explored grandmothers’ (mothers/mothers-in-law) influence on pregnant and breastfeeding women’s health-related decisions and their potential to support use of HIV prevention products utilizing qualitative data collected from grandmothers, HIV-uninfected, currently/recently pregnant or breastfeeding women and male partners of currently/recently pregnant or breastfeeding women during the MTN-041/MAMMA study. Results: Grandmothers were described as important sources of information, playing both supportive and influencer roles, due to personal maternal experience and generational knowledge. Grandmothers expressed willingness to support pre-exposure prophylaxis (PrEP) use and agreed with other groups that this decision should be made by women themselves and/or with partners. Conclusion: With the right framing and approach, grandmothers’ supportive roles can optimise uptake and adherence to biomedical HIV prevention and reduce HIV acquisition among pregnant and breastfeeding women in these communities.

    Impact of the Dapivirine Vaginal Ring on Sexual Experiences and Intimate Partnerships of Women in an HIV Prevention Clinical Trial: Managing Ring Detection and Hot Sex
    (AIDS and Behavior, 2018) Laborde, Nicole D.; Pleasants, Elizabeth; Reddy, Krishnaveni; Atujuna, Millicent; Nakyanzi, Teopista; Chitukuta, Miria; Naidoo, Sarita; Palanee-Phillips, Thesla; Baeten, Jared M.; Montgomery, Elizabeth T.
    Vaginally-inserted HIV prevention methods have been reported to impact the sexual experience for women and their partners, and hence impacts acceptability of and adherence to the method. We analyzed in-depth interviews and focus group discussions about participants’ sexual experiences while wearing the ring, collected during the MTN-020/ASPIRE phase 3 safety and effectiveness trial of a dapivirine vaginal ring for HIV prevention in Malawi, South Africa, Uganda, and Zimbabwe. Most women reported that partners did not feel the ring during sex, however, women felt they had to manage their partners’ interaction with or reaction to the ring. In maintaining positive relationships, women were concerned about partners’ discovering ring use and about ensuring that partners had a good sexual experience with them. Finally women were concerned about how they themselves experienced sex with the ring. Some found that the ring made the vaginal environment more desirable for their partners and themselves

    The Influence of Perceived Dapivirine Vaginal Ring Effectiveness on Social Disclosure and Ring Adherence
    (AIDS and Behavior, 2013) Stoner, Marie C. D.; Brown, Elizabeth R.; Palanee‑Phillips, Thesla; Mansoor, Leila E.; Tembo, Tchangani; Nair, Gonasagrie; Akello, Carolyne; Seyama, Linly; Jeenarain, Nitesha; Naidoo, Logashvari; Mgodi, Nyaradzo; Hunidzarira, Portia; Chitukuta, Miria; Straten, Ariane van der
    We analyzed data from 1428 users of the dapivirine vaginal ring, who participated in the MTN-020/ASPIRE phase III trial and subsequent open-label extension MTN-025/HOPE trial, to examine relationships between perceived ring protection, social disclosures, and self-reported ring adherence. In HOPE, 77% perceived the ring to be highly effective, and this view was associated with speaking: (a) to a greater number of people about the study, (b) with other participants, (c) to more people who were in favor of the ring, and (d) to more people whose opinions were valued. Reported adherence was not directly associated with perceived protection but was associated with disclosing to someone who was in favor of the ring. These findings suggest the importance of women’s internalized ideas about the protective benefits of the DVR in sharing information about the ring and the importance of social support on adherence

    Negative rumors about a vaginal ring for HIV-1 prevention in sub-Saharan Africa
    (HHS Public Access, 2019) Chitukuta, Miria; Duby, Zoe; Katz, Ariana; Nakyanzi, Teopista; Reddy, Krishnaveni; Palanee-Phillips, Thesla; Tembo, Tchangani; Etima, Juliane; Musara, Petina; Mgodi, Nyaradzo M.; Straten, Ariane van der
    Rumours may influence health-related behaviours, including uptake and adherence to HIV prevention products. This ASPIRE study assessed the safety and effectiveness of a vaginal ring delivering the antiretroviral dapivirine for HIV prevention in Africa. We explored negative rumours about study participation and the vaginal ring amongst study participants and their communities in Malawi, Uganda, South Africa and Zimbabwe. Two hundred and fourteen women participated in either single or serial in-depth interviews, or a focus group discussion. Three key findings emerged in the data. Firstly, rumours reflected fears concerning the ring and trial participation. Given the historical-political context of the countries in which the trial was conducted, the ring’s investigational nature and its foreign origin, ring use was rumoured to cause negative health outcomes such as cancer and infertility and was also associated with practices such as witchcraft or Satanism; salience of these rumours varied by country. Secondly, rumours reportedly affected participants’ adherence to the ring, and other women’s willingness to participate in the study. Finally, participants reported that participant engagement activities helped address rumours, resulting in enhanced trust and rapport between staff and participants.
