RESUMEN

Open-Label Extension (OLE) studies are important in the drug development process and are used to further support the licensing applications and regulatory approvals of products. We aimed to understand why women chose to join the HOPE OLE study - where women were offered the dapivirine vaginal ring after two pivotal trials were completed - through data collected from individual in-depth interviews. Ten women at each of the six HOPE research sites in Lilongwe, Malawi; Durban (2 sites) and Johannesburg, South Africa; Kampala, Uganda; and Chitungwiza, Zimbabwe, were enrolled (n = 60). Access to an effective user-initiated HIV prevention product was one of the main reasons women joined HOPE. Although many participants worried that their male partners might expose them to HIV, they chose to remain in their relationships and avoid conflict or confrontation with their partners by discreetly using the ring to protect themselves. Other reasons for joining were quality healthcare, reimbursement and altruism. Researchers should better understand social and personal motivators behind research participation in order to recognize community sociocultural norms and its influences on product acceptability and adherence challenges.

RESUMEN

The concept of efficacy, and how HIV prevention products biologically work can be complex. We report on women's interpretation of efficacy of the dapivirine vaginal ring and how they understood it to work to prevent HIV during the MTN-025/HOPE study through data collected from individual in-depth interviews. Ten women at each of the 6 HOPE research sites in Lilongwe, Malawi; Durban (2 sites) and Johannesburg, South Africa; Kampala, Uganda; and Chitungwiza, Zimbabwe, were enrolled (n = 60). Despite its partial efficacy, women trusted the ring to prevent HIV even when condoms were not used. The action of the ring was understood by most, however, there were misunderstandings around how quickly or slowly protection was offered when the ring was inserted or removed. Counselling sessions adapted to address partial efficacy, a multi-layered HIV prevention plan and how study products work could alleviate inconsistent adherence and diminished protection and further support women in receiving the best protection from their HIV prevention product of choice.

RESUMEN

Women account for a disproportionate percentage of new HIV infections in sub-Saharan Africa indicating a need for female-initiated HIV prevention options congruent with their lifestyles. The dapivirine vaginal ring for HIV prevention is one such option. We explored the interest of women, who used this ring during the Microbicide Trials Network's ASPIRE and HOPE studies, in using the ring post-licensure and what they perceived as important considerations for future use. We also explored perspectives of HOPE participants' male partners on their involvement in their partners' future ring use. Women appeared keen to use the ring in the future and expressed desires for easy access, support for both ongoing and new users and intense community engagement. In parallel, male partners indicated high levels of interest in supporting their partners' ring use and being involved in ring use decision making. These data offer important insights for ring rollout planning and engagement activities.

RESUMEN

In the Phase IIIB MTN-025/HOPE open label extension trial, participants were offered the dapivirine vaginal ring as HIV prophylaxis, and those who accepted the ring received semi real-time individual adherence feedback, based on residual drug level (RDL) from returned rings, during Motivational Interviewing-based counseling. Counseling messages, based on the best knowledge at the time, framed RDL results in terms of ring use and HIV protection, from no use /no protection (0 RDL) to high use /high protection (3 RDL). At six HOPE sites, in-depth-Interviews (IDIs) about RDL were conducted with 64 participants who had received at least one RDL result. We found mixed interpretations of what the RDL meant and strong emotional reactions with a focus on the external validation of the level itself. Counseling was critical to help participants process their reactions to the RDL and make decisions accordingly (i.e., persistence, adherence improvement, and/or switching to another HIV prevention method). Providing drug adherence feedback was complex to implement yet proved useful as a component of a multi-pronged adherence support strategy.

RESUMEN

As demonstrated by the Phase III clinical trial, MTN-020/ASPIRE, the monthly dapivirine vaginal ring is well tolerated and reduces the risk of HIV-1 as a woman-initiated prevention option. This analysis uses data from the follow-on MTN-032/Assessment of ASPIRE and HOPE Adherence (AHA) qualitative study to understand how perceptions (or misperceptions) of ring efficacy may have influenced behavior during ASPIRE, and affected intention to use the ring in future ring projects, specifically HOPE, the planned open-label extension study. Single in-depth interviews (n = 98) and 12 focus group discussions (n = 89) were conducted with women at seven sites in Malawi, South Africa, Uganda and Zimbabwe. Eligibility included participation in the ASPIRE active arm, and ring use for ≥ 3 months or at least 1 month if seroconversion occurred. Interviews were audio-recorded, transcribed into English, coded in Dedoose and thematically analyzed. Demographic and behavioral questionnaire data were summarized in Stata. Most AHA participants perceived the ring to be effective, and described simply trusting it or having confidence in it because they, or other participants in risky situations, remained HIV-uninfected. Participants described ring efficacy after receiving ASPIRE results as a binary assessment: the ring worked or not. Many did not remember exact efficacy percentages because of lack of comprehension or memory but recalled key details about age differences. The majority expressed interest in future ring use. There is a need to investigate improved ways of explaining placebo-controlled trials and efficacy to women in Sub-Saharan Africa. Now that ring efficacy, is known, these benefits must be well communicated, and understood by end-users and key stakeholders. Engagement with end-users to construct effective messages and to develop tools to measure understanding of partial efficacy will be essential.

RESUMEN

The dapivirine vaginal ring has been well-tolerated and shown to prevent HIV in clinical trials. The ring is female initiated, yet endorsement for use is sought from male partners in many relationships. In clinical studies, participants have expressed worries about men detecting rings during vaginal sex, which introduces concerns about product use disclosure, sexual pleasure, penile harm, inter-partner dynamics, and ring removals. This study reports African men's firsthand sexual experiences with the ring. Qualitative data were captured through 11 focus group discussions and one in-depth interview with 54 male partners of ring-users at six research sites in Malawi, South Africa, Uganda and Zimbabwe. Following a semi-structured guide, and using demonstration rings, vulva and penis models, men were asked to discuss the ring's impact on sex and views on male engagement and ring use. Interviews were facilitated by local male social scientists, audio-recorded, translated into English, and analyzed thematically. 22 (41%) of the male partners reported feeling the ring during sex, often attributed to perceived incorrect insertion. Many men described the ring as "scratching" the tip of their penises, and sensations of "prodding" something that "blocked" the vagina and prohibited "full entry". In most cases, feelings dissipated with time or when sexual fluids increased. Less common descriptions included perceiving the vaginal texture, wetness and size as different, which increased pleasure for some, and decreased for others. Over half (59%) never noticed the ring; some attempting and failing to feel it during intercourse. A majority of men reported that the ring did not lead to changes in sexual positions, feelings, frequency or experience of sex, although some were initially afraid that the ring was a "magic snake" or "potion". Male partners expressed strong opinions that ring use was a shared prevention responsibility that men should be engaged in, especially for maintaining trust and open communication in relationships. The ring was noticed by many male partners, particularly during women's initial stages of ring use, although this led to few sexual problems or changes. Nevertheless, results suggest that risk of ring discovery should be discussed with women to mitigate any potential negative reactions or social harm. Strategies to increase male partner engagement will enhance support of this prevention method for women.

RESUMEN

Globally, HIV affects women disproportionally to men, particularly in sub-Saharan Africa. While the monthly dapivirine vaginal ring (VR) is a promising female-initiated HIV prevention method, it is important to understand how well the ring is liked. With former participants of HOPE, an open-label extension trial of the ring, we used emoji stickers and a worksheet to explore female end-user's acceptability of and opinions about the VR. We aimed to understand these participants' opinions about the VR, and how they had changed over time, particularly in the context of known efficacy of the dapivirine VR. Most participants easily understood the exercise and how to use the emoji stickers, with a few exceptions. For those who had trouble understanding how to use the emoji, interviewer support and encouragement helped them to understand and continue with the exercise. Emoji interpretation varied widely with participants using the same emoji to express divergent opinions. Using the emoji stickers, participants expressed mostly positive opinions of the vaginal ring for HIV prevention, with some lingering concerns about the product's partial effectiveness. This paper contributes to the literature supporting the assertion that the dapivirine VR for HIV prevention is acceptable to women, and that acceptability increases with time and proper education. This analysis also provides evidence that emoji visual tools can enhance understanding of acceptability of an intervention when used in qualitative research.

RESUMEN

The monthly dapivirine vaginal ring has proven efficacious in reducing HIV incidence in two Phase 3 clinical trials. When considering the potential future availability of the ring to the public, key questions remain about the feasibility of integrating the ring as an HIV prevention intervention into women's lives. We conducted qualitative mapping interviews (n = 66) among women enrolled in MTN-025/HOPE, an open-label trial conducted in Malawi, South Africa, Uganda and Zimbabwe, to examine how home environments influenced use of the dapivirine vaginal ring. Most women had secure places to store their rings including wardrobes, suitcases, and bags. The primary concerns for ring storage were potential tampering from children or rodents. Household overcrowding limited the privacy some women had which made removal and insertion of vaginal rings challenging. Despite these challenges, ring storage, insertion, and removal was feasible across social and living contexts.

RESUMEN

BACKGROUND: Clinical trials have found that a monthly dapivirine vaginal ring was well-tolerated and reduced HIV-1 risk among women in sub-Saharan Africa. However, in order for the ring or other novel prevention methods to have optimal impact, it is necessary to understand and address women's challenges to uptake and adherence. This paper provides insight into a few key challenges noted by women using the ring and contraceptives simultaneously. METHODS: The qualitative portion of the MTN-020/ASPIRE study consisted of data collection using single in-depth interviews, serial in-depth interviews, and focus group discussions, conducted with 214 participants across 15 sites in Malawi, South Africa, Uganda and Zimbabwe. A coding team used qualitative analysis software to identify themes within the interviews. RESULTS: The primary qualitative themes among participant data pertained to side effects. Participants reported negative side effects related to menses, in some cases attributing these effects to their contraceptives and in others to the vaginal ring. Participants also expressed concern over the long-term impact of contraception and ring use on fertility, including the reversibility of the contraceptive, especially among nulliparous women. CONCLUSIONS: Women's attitudes toward contraceptives can impact their willingness to concurrently use and adhere to a novel HIV prevention product. To optimize the potential of both prevention products, researchers should pre-emptively address concerns about contraceptive impact on fertility and counsel women about the expected side effects of contraceptives versus the ring.

RESUMEN

BACKGROUND: We previously demonstrated that automated, Web-based pain coping skills training (PCST) can reduce osteoarthritis pain. The present secondary analyses examined whether this program also changed coping strategies participants identified for use in hypothetical pain-related situations. METHOD: People with hip/knee osteoarthritis (n = 107) were randomized to Web-based PCST or standard care control. At baseline and post-intervention, they reported their pain severity and impairment, then completed a task in which they described how they would cope with pain in four hypothetical pain-related situations, also reporting their perceived risk for pain and self-efficacy for managing it. We coded the generated coping strategies into counts of adaptive behavioral, maladaptive behavioral, adaptive cognitive, and discrete adaptive coping strategies (coping repertoire). RESULTS: Compared to the control arm, Web-based PCST decreased the number of maladaptive behavioral strategies generated (p = 0.002) while increasing the number of adaptive behavioral strategies generated (p = 0.006), likelihood of generating at least one adaptive cognitive strategy (p = 0.01), and the size of participants' coping repertoire (p = 0.009). Several of these changes were associated with changes in pain outcomes (ps = 0.01 to 0.65). Web-based PCST also reduced perceived risk for pain in the situations (p = 0.03) and increased self-efficacy for avoiding pain in similar situations (p < 0.001). CONCLUSION: Salutary changes found in this study appear to reflect intervention-concordant learning.

RESUMEN

Women are disproportionately at risk of acquiring HIV in East and Southern Africa, despite global declines in incidence. Female-initiated HIV prevention methods, like the dapivirine vaginal ring, are needed to end the HIV epidemic. In-depth interviews and focus groups retrospectively explored peer influence on acceptability of and adherence to the ring during the ASPIRE trial, a phase III placebo-controlled trial. Results were analyzed using an inductive analytic approach. Study participants (peers) of all ages and adherence groups developed important interpersonal connections and reported being more open and honest with each other than with external peers or study staff. Study peers who knew each other prior to joining appeared to have a stronger influence on each other's adherence than peers who met in the study. External peers provided primarily negative input about the ring and study, which sometimes led to ring removals. Peers' influence on each other's behavior in both prosocial and detrimental manners could have repercussions on adherence to a biomedical intervention, and consequently, individual disease risk and clinical trial outcomes. Future ring demonstration and implementation studies could use peer networks to intentionally influence uptake and adherence to the ring.

RESUMEN

We assessed the interference between vaginal ring use and menses among women who participated in the qualitative component of the MTN-020/ASPIRE vaginal ring trial in Malawi, South Africa, Uganda and Zimbabwe (N = 214). A common reason for imperfect ring adherence and premature removal of the vaginal ring cited by participants related to vaginal bleeding or menses. Whereas self-reporting via survey questions suggested that the majority (60%) of women did not mind wearing the ring while menstruating, and did not remove it (91%) during menses, in the qualitative interviews women frequently described removing the ring during menses. Their reasons included hygiene, beliefs that the ring blocked the flow of menstrual blood, fears that the ring would come out with blood or during tampon removal, and concerns around an 'overburdened' vagina. Examining women's narratives and subjective experiences related to menstruation helps build a better understanding of factors affecting ring use and adherence.

RESUMEN

Biomedical HIV prevention trials increasingly include evidence-based adherence counseling to encourage product use. To retain effectiveness, interventions must contain key components. Monitoring counseling fidelity ensures inclusion of components but is challenging in multinational contexts with different languages and scarce local supervision. The MTN-025/HOPE Study, a Phase 3b open-label trial to assess continued safety of and adherence to the dapivirine vaginal ring for HIV prevention, was the largest such trial to integrate fidelity monitoring using audio recordings of counseling sessions. We describe the monitoring process, along with counselor and participants' perceptions of it, which were collected via quantitative online survey (counselors only N = 42) and in-depth interviews with a subset of counselors (N = 22) and participants (N = 10). Sessions were conducted in five languages across 14 study sites in four countries. In total, 1238 sessions (23% of submitted sessions) were randomly selected and rated. Assessment of interrater reliability was essential to address drift in ratings. Counselors were apprehensive about being monitored, but appreciated clear guidance and found ratings very helpful (mean = 6.64 out of 7). Some participants perceived sessions as time-consuming; others found monitoring improved counseling quality. Fidelity monitoring of counseling sessions in mult-isite biomedical HIV studies is feasible and supportive for counselors.

RESUMEN

Socio-cultural beliefs and practices surrounding menses influence women's sexual and reproductive health behaviors and decision-making. We analyzed menstrual experiences within the context of the MTN-020/ASPIRE clinical trial during which women were asked to use a monthly vaginal ring for HIV prevention. The qualitative component of the trial was conducted during February 2013-June 2015, included interviews and focus group discussions with 214 women aged 18-42, in Malawi, Zimbabwe, Uganda, and South Africa. Emotions of shame, embarrassment and disgust relating to menses emerged. Menstruation was referred to using euphemistic terms or language about dirtiness. Women were uncomfortable touching their own menstrual blood when removing vaginal rings and felt embarrassed about study staff seeing blood on returned rings. Despite reassurances, women felt ashamed performing study procedures while menstruating, leading to missed study visits. Women's aversion to menstrual blood was linked to narratives about avoiding sex during menses and beliefs about its potential harms. Women associated men's disgust pertaining to menstrual blood with men's willingness to use condoms for sex only during menses, highlighting another way through which socio-cultural beliefs and practices around menstruation affect HIV protective behaviours. These findings provide novel insight into menstrual shame among women in these four countries.

RESUMEN

BACKGROUND: In biomedical prevention trials, correct and consistent use of the investigational product is crucial to determine efficacy. Product adherence in VOICE, a phase 2B randomized trial of a vaginal gel and oral tablets for HIV prevention, was low (~ 34%), yet self-reported adherence and retention was high (> 90%). This analysis from VOICE-D, a post-trial qualitative ancillary study, explores motivations to participate in VOICE, and possible sources of misalignment between the stated priorities of the trial and the participants. METHODS: VOICE-D enrolled 171 former VOICE participants to investigate, among other things, reasons for joining and remaining in the trial. Local language in-depth interviews and focus groups were transcribed and translated into English and coded and analyzed using NVivo. Data on motivation to join obtained from a VOICE termination visit survey of 106 participants were also analyzed to corroborate the VOICE-D findings. RESULTS: Participants primarily participated for personal health benefits (e.g. free healthcare and HIV testing) and reported remaining enrolled from a sense of commitment to the trial. Altruistic motivations were the most commonly stated motivation on the termination visit survey; qualitatively, many of those stating altruistic reasons also desired personal health benefits. Joining for financial reimbursement was not commonly mentioned. Social networks influenced recruitment and spread therapeutic misconception. CONCLUSIONS: Women's participation for personal health benefits highlighted their desire to monitor their HIV risk and overall health. Helping participants view use of investigational products as improving social capital and reminding participants of their study responsibilities may improve trial outcomes. Understanding the reasons for participating in studies will help to ensure alignment between priorities of researchers and participants.

RESUMEN

Rumours may influence health-related behaviours, including the uptake of and adherence to HIV prevention products. This 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. In total 214 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 to be associated with practices such as witchcraft or Satanism. The 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.

RESUMEN

Accurate estimates of study product use are critical to understanding and addressing adherence challenges in HIV prevention trials. The VOICE trial exposed a significant gap between self-reported adherence and drug detection. The VOICE-D qualitative study was designed to better understand non-adherence during VOICE, and was conducted in 2 stages: before (stage 1) and after (stage 2) drug detection results were provided to participants. Transcripts from 44 women who participated in both stages were analysed to understand the effect of presenting drug detection data on narratives of product use. Thirty-six women reported high adherence in stage 1, yet admitted non-use in stage 2, three reported high adherence in both stages (contrary to their drug detection results) and five had consistent responses across both stages and drug results. Presenting objective measures of use may facilitate more accurate product use reporting and should be evaluated in future prevention trials.

RESUMEN

As reviewed in the article by Perry and colleagues (2014) in this volume, ample evidence has documented the contributions of peer support (PS) to health, health care, and prevention. Building on that foundation, this article discusses characteristics, contexts, and dissemination of PS, including (a) fundamental aspects of the social support that is often central to it; (b) cultural influences and ways PS can be tailored to specific groups; (c) key features of PS and the importance of ongoing support and backup of peer supporters and other factors related to its success; (d) directions in which PS can be expanded beyond prevention and chronic disease management, such as in mental health or interventions to prevent rehospitalization; (e) other opportunities through the US Affordable Care Act, such as through patient-centered medical homes and chronic health homes; and (f) organizational and policy issues that will govern its dissemination. All these demonstrate the extent to which PS needs to reflect its contexts--intended audience, health problems, organizational and cultural settings--and, thus, the importance of dissemination policies that lead to flexible response to contexts rather than constraint by overly prescriptive guidelines.

RESUMEN

BACKGROUND: The dapivirine vaginal ring ("the ring") reduced HIV acquisition by about 35% in phase III trials, with modeling from open-label extension trials estimating 50% HIV protection with consistent use. The ring may be used without male partner knowledge. The Assessment of ASPIRE and HOPE Adherence (AHA) substudy aimed to understand the impact of sociocontextual issues on ring adherence. This subanalysis provides insight into disclosure and male partner influence on ring acceptability. METHODS: Data were collected using 4 focus group discussions with 18 male partners of phase III trial participants at 2 sites in KwaZulu-Natal, South Africa. Qualitative data were coded, summarized by urban vs. rural location, and analyzed thematically. RESULTS: Male partners aged 23-49 years wanted to be informed about the ring use to maintain the trust in their relationships. Their initial response to the ring was characterized by fear due to perceived impact of the ring on their female partner's reproductive system, their penile safety, and that the ring would encourage women to engage in unprotected sex and infidelity. Over time and with information and experience with having a partner who had used the vaginal ring, this fear transformed to support for women to have their own HIV prevention option. CONCLUSION: Male partners supported the ring as an HIV prevention method for women but wanted to be informed about its use.

RESUMEN

ABSTRACT: Daily oral pre-exposure prophylaxis (PrEP) adherence is challenging. We explored African adolescent girls and young women's (AGYW) perceptions of the social influencers of their PrEP use and the social influencers' PrEP knowledge and support (six focus group discussions; 33 South African and Kenyan AGYW) in the Prevention Options for Women Evaluation Research demonstration project. Participants completed a social mapping exercise indicating strength and direction of influence of members in their social networks. Mothers and counselors were identified as positive influencers and most influential by >50% of participants, sex partners were labeled negative influencers or both positive and negative, and best friends were mostly positive influencers. HIV- and PrEP-related stigma were the major reasons influencers were identified as negative. Participants wanted their social networks to be better educated about PrEP by someone other than the AGYW themselves (e.g., clinic staff) and to support their PrEP use. To improve PrEP adherence, community- and peer-based PrEP sensitization and delivery interventions should be evaluated.
