PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0003313. [PMID: 38959214 PMCID: PMC11221757 DOI: 10.1371/journal.pgph.0003313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 05/11/2024] [Indexed: 07/05/2024]
Abstract
Family planning (FP) is an essential component of public health programs and significantly impacts maternal and child health outcomes. In Uganda, there is a need for a comprehensive review of the existing literature on FP to inform future research and programmatic efforts. This scoping review aims to identify factors shaping the use of FP in Uganda. We conducted a systematic search of eight scholarly databases, for qualitative studies on FP in Uganda. We screened the titles and abstracts of identified articles published between 2002-2023 and assessed their eligibility based on predefined criteria. We extracted data from the 71 eligible studies and synthesized the findings using thematic analysis and the Ecological Systems Theory (EST) individual, interpersonal, community, institutional, and policy-level determinants. Findings reveal the interplay of factors at different socio-ecological levels influencing family planning decisions. At the individual level, the most common determinants related to the EST were knowledge and attitudes of FP. Interpersonal dynamics, including partner communication and social support networks, played pivotal roles. Community-level factors, such as cultural norms and accessibility of services, significantly influenced family planning practices. Institutional and policy-level factors, particularly a healthcare system's quality and policies, also shaped use. Other themes included the intersection of HIV/AIDS on FP practice and Ugandan views of comprehensive abortion care. This scoping review underscores the intricate socio-ecological fabric shaping FP in Uganda. The findings highlight the need for targeted interventions to increase knowledge and awareness of FP, improve access to services, and address social and cultural norms that discourage contraceptive use. Policymakers and program implementers should also consider gender dynamics and power imbalances in FP programs to ensure they are equitable and effective.

Self-reported removal and expulsion of the dapivirine vaginal ring: qualitative reports from female ring users and their male partners in the Ring Study (IPM 027). BMC Public Health 2024; 24:1458. [PMID: 38822304 PMCID: PMC11140940 DOI: 10.1186/s12889-024-18795-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 05/08/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND/AIMS The dapivirine vaginal ring is a self-administered, women-initiated, discreet, long-acting HIV-1 prevention option for women. It was found to be safe and effective in healthy HIV-negative women who adhered to product use instructions, and has been approved for use in women aged 18 and older in some African countries. A qualitative study was conducted to explore participants' and their male partners' discussions on accidental/purposeful vaginal ring removals during The Ring Study (IPM 027 clinical trial). METHODS Data were collected via in-depth interviews and focus group discussions with female trial participants and their male partners, from seven research centres in South Africa and Uganda. Data were thematically analysed using NVivo. RESULTS More participants reported purposeful ring removals than accidental expulsions. Various factors influenced purposeful ring removal - including individual (discomfort during use/sex and to clean it), partner (to show them, because of discomfort during sex, to test if partners could feel it, and concerns of harm), organisational (doctor's request), and socio-cultural (rumours about sickness and infertility). Some described their own ring use removal, others discussed why other participants removed their rings. CONCLUSIONS Vaginal ring adherence is critical to improve and support product efficacy. Counselling on vaginal anatomy, vaginal ring insertion and importance of adherence is important to minimise vaginal ring removal. Couples counselling is also important to facilitate support and long-term vaginal ring adherence behaviour. Understanding factors influencing vaginal ring adherence is important for tailoring and targeting messages to support correct and consistent vaginal ring use as it is made available to the public.

Am J Obstet Gynecol 2024; 230:548.e1-548.e8. [PMID: 38295968 DOI: 10.1016/j.ajog.2024.01.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 01/03/2024] [Accepted: 01/19/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND The US Food and Drug Administration-approved segesterone acetate and ethinyl estradiol ring-shaped contraceptive vaginal system, known as Annovera (Sever Pharma Solutions/QPharma, Malmö, Sweden), was inserted and removed under a woman's control for a 21 day in and 7 day out regimen for up to 13 cycles of use. OBJECTIVE We aimed to describe the patterns of ring expulsion over time, to identify potential predictors of expulsion, and to evaluate the impact of expulsions on method discontinuation and pregnancy risk. STUDY DESIGN Using data from 2064 participants who were enrolled in 2 multinational phase 3 clinical trials on the use of this contraceptive vaginal system, we examined data from participants' daily diaries for documentation of complete ring expulsion. We modeled the odds of reported expulsions over time with adjustment for background and demographic characteristics using mixed-effects logistic regression models with random intercepts. We compared the probability of continuation between those who did and those who did not report expulsions in the first cycle of use using survival analysis and hazards modeling. To determine if expulsions during the first cycle of use affected the risk for pregnancy, we calculated Pearl Indices. RESULTS Most participants (75%) never experienced any expulsions during any cycle of use, and 91% to 97% did not experience an expulsion during any 1 cycle. The incidence of expulsion was highest in cycle 1 (9%). The odds of experiencing expulsions decreased by half in cycles 2 to 8 when compared with cycle 1 (0.48; 95% confidence interval, 0.40-0.58), and in cycles 9 to 13, expulsions were about a third of that in cycle 1 (0.32; 95% confidence interval, 0.26-0.41). Of those who did experience expulsions, most (62%-84%) experienced ≤2 expulsions per cycle. Participants from study sites in Latin America vs those in the United States had higher odds of not experiencing an expulsion (odds ratio, 1.95; 95% confidence interval, 1.45-2.63). Women with a higher education level had higher odds of experiencing an expulsion. Notably, parity, age, and body mass index were not associated with expulsion. Participants who experienced any expulsions in cycle 1 were more likely to discontinue use early (hazard ratio, 1.28; 95% confidence interval, 1.14-1.43) than participants who did not have an expulsion. The Pearl Index for participants who had expulsions during cycle 1 was 3.99 (95% confidence interval, 1.29-9.31), which was higher than that among participants who reported no expulsions (Pearl Index, 2.39; 95% confidence interval, 1.61-3.41), but the overlapping confidence intervals indicate that there is not sufficient evidence to demonstrate an association between expulsions and pregnancy risk. CONCLUSION Expulsions were infrequent overall, decreased with subsequent cycles of use, and were not associated with body mass index or parity. Early discontinuation of product use was higher among participants who experienced an expulsion during cycle 1. Although it is unclear whether pregnancy risk was associated with expulsions, early recognition of expulsions among users may identify those at higher risk for discontinuation and may highlight when enhanced anticipatory counselling and guidance may be advantageous.

Abstract
The Microbicide Trials Network 042 study (MTN-042/DELIVER) is a two-arm, randomized, open-label Phase 3b trial that is evaluating the safety, adherence, and acceptability of the monthly ring and daily oral PrEP among HIV-uninfected pregnant people in four African countries. This analysis focuses on acceptability data captured qualitatively from a subset (n = 48) of the 150 people in the first cohort of the trial who were enrolled in late-stage pregnancy at 36 to 38 weeks gestational age and followed until after delivery. Single IDIs were conducted by trained interviewers at each clinic site using a semi-structured guide. Data excerpts of key codes pertaining to acceptability, pregnancy, and maternal health were summarized, reviewed and interpreted by multinational analyst teams. Although the product use period was relatively short, the data suggested several acceptability findings that may directly translate to longer durations of product use in pregnancy. The first was the overarching maternal sentiment that being able to protect both oneself and their baby was highly valued. The second was the importance of counseling support from providers not only because participants used methods that might generate side effects, but because pregnancy itself is a period with its own set of side effects. The third was that, similar to non-pregnant participants in other trials, here study products were generally liked and described as easy to use. Concerns about ring and oral PrEP use could be addressed with provider counseling and support and should form an essential component rollout among pregnant people.

Abstract
The success of long-acting (LA) drug delivery systems (DDSs) is linked to their biocompatible polymers. These are used for extended therapeutic release. For treatment or prevention of human immune deficiency virus type one (HIV-1) infection, LA DDSs hold promise for improved regimen adherence and reduced toxicities. Current examples include Cabenuva, Apretude, and Sunlenca. Each is safe and effective. Alternative promising DDSs include implants, prodrugs, vaginal rings, and microarray patches. Each can further meet patients' needs. We posit that the physicochemical properties of the formulation chemical design can optimize drug release profiles. We posit that the strategic design of LA DDS polymers will further improve controlled drug release to simplify dosing schedules and improve regimen adherence.

Abstract
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 use and physical sensation in situ, impacts on sex, partner's opinion, and likelihood of future use. We used Poisson regression models with robust standard errors to compare risk of acceptability challenges by baseline history of transactional sex. At product discontinuation, women exchanging sex found the ring comfortable (90%), easy to insert (92%) and nearly all (96%) were likely to use the ring in the future. Women who had exchanged sex were more likely to report feeling the ring during sex (ARR 1.43, 95% CI: 1.09, 1.89; p = 0.01) and slightly more likely to mind wearing the ring during menses (ARR 1.22, 95% CI: 1.01, 1,46; p = 0.04) and during sex (ARR 1.22, 95% CI: 1.02, 1.45; p = 0.03). Messaging and counseling should include enhanced support for use during sex and menses to support optimal use.

Two into one does go: Formulation development of a multipurpose combination vaginal ring releasing dapivirine and metronidazole for prevention of HIV infection and treatment of bacterial vaginosis. Int J Pharm 2023; 648:123572. [PMID: 37926178 DOI: 10.1016/j.ijpharm.2023.123572] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 10/20/2023] [Accepted: 10/31/2023] [Indexed: 11/07/2023]
Abstract
Bacterial vaginosis (BV) is a common but often asymptomatic dysbiosis of the human vagina characterized by an imbalance in the normal vaginal microbiota due to loss of lactobacilli and an overgrowth of certain anaerobic bacteria. While BV itself is not a sexually transmitted infection, it is associated with an increased risk in women of various sexually acquired infections, including human immunodeficiency virus (HIV) infection. There is, therefore, a strong rationale for pursuing new multipurpose products that seek to treat or prevent BV alongside preventing HIV infection. With the dapivirine-releasing vaginal ring for HIV prevention now approved in several African countries, here we report formulation development of a next-generation ring product that releases both dapivirine (DPV) and the antibiotic drug metronidazole (MET). Following thermal analysis studies to characterize the phase behaviour of DPV-MET mixtures and rheological analysis to assess the cure characteristics of the active silicone elastomer mixes, matrix-type rings were manufactured containing 25 or 200 mg DPV in combination with 100, 250, 500, 1000 or 2000 mg MET. The results for drug content, in vitro release, mechanical testing, and Gardnerella vaginalis time-kill experiments demonstrate the feasibility of incorporating both DPV and MET in a matrix-type ring formulation and indicate that clinically effective release rates may be possible.

Abstract
Effective use of oral pre-exposure prophylaxis (PrEP) has been low among adolescent girls and young women (AGYW) in Eastern and Southern Africa, partly due to stigma and opposition from key influencers. Understanding AGYW's experiences of disclosure of different PrEP modalities to key influencers may inform strategies to motivate uptake and adherence. We analyzed qualitative in-depth interviews and focus group discussions data from 119 participants in the MTN-034/REACH (Reversing the Epidemic in Africa with Choices in HIV Prevention) study of oral PrEP and the dapivirine vaginal ring (ring) to explore AGYW's disclosure experiences. We found that AGYW disclosure experiences varied across influencers and product type. The ring was disclosed less often to most influencers, except partners, because it was discreet. Oral PrEP was disclosed more often, because pills were more common and to avoid HIV stigma given that oral PrEP resembled HIV treatment. Ultimately, disclosure typically led most key influencers to support product use through reminders and encouragement. While disclosure yielded positive support from influencers, further community awareness of both PrEP products is essential to reduce potential opposition and perceived stigma.Clinical Trial Number: NCT03593655.

A subsample of 52 participants were purposively sampled to participate in an in-depth interview (IDI). Breastfeeding participants found both study products to be acceptable, and easy to use. A common motivation for product use was to protect the baby from HIV, although participants' understanding of how the study drug would work to protect their babies was often unclear. While most participants did not report experiencing side effects, fears about side effects were common as both initial worries about how the study products would affect their health and the health of their baby, and increased anxiety that health issues experienced by them, or their baby were from the products.

How a menu of adherence support strategies facilitated high adherence to HIV prevention products among adolescent girls and young women in sub-Saharan Africa: a mixed methods analysis. J Int AIDS Soc 2023; 26:e26189. [PMID: 37936551 PMCID: PMC10630658 DOI: 10.1002/jia2.26189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 10/18/2023] [Indexed: 11/09/2023] Open
Abstract
INTRODUCTION Effective use of pre-exposure prophylaxis (PrEP) has been low among adolescent girls and young women (AGYW) in sub-Saharan Africa. The MTN-034/REACH trial offered AGYW a menu of adherence support strategies and achieved high adherence to both daily oral PrEP and the monthly dapivirine vaginal ring. Understanding how these strategies promoted product use could inform the design of adherence support systems in programmatic settings. METHODS REACH was a randomized crossover trial evaluating the safety of and adherence to the ring and oral PrEP among 247 HIV-negative AGYW (ages 16-21) in South Africa, Uganda and Zimbabwe from January 2019 to September 2021 (NCT03593655). Adherence support included monthly counselling sessions with drug-level feedback (DLF) plus optional daily short message service (SMS) reminders, weekly phone or SMS check-ins, peer support clubs, "peer buddies" and additional counselling. Counsellors documented adherence support choices and counselling content on standardized forms. Through focus groups, serial in-depth interviews (IDIs) and single IDIs (n = 119 total), we explored participants' experiences with adherence support and how it encouraged product use. RESULTS Participants received counselling at nearly all visits. DLF was provided at 54.3% of sessions and, across sites, 49%-68% received results showing high adherence for oral PrEP, and 73%-89% for the ring. The most popular support strategies were in-person clubs and weekly calls, followed by online clubs, additional counselling and SMS. Preferences differed across sites but were similar for both products. Qualitative results demonstrated that the REACH strategies supported adherence by providing information about HIV and PrEP, continually motivating participants, and supporting the development of behavioural skills and self-efficacy, aligning with the Information, Motivation, and Behavioural Skills (IMB) model. Effectiveness was supported by three foundational pillars: strong interpersonal relationships with counsellors; ongoing, easily accessible support and resources; and establishing trust in the counsellors and study products through counsellor relationships, peer-to-peer exchange and DLF. CONCLUSIONS Implementation programmes could support effective PrEP use by offering a small menu of counsellor- and peer-based support options that are youth-friendly and developmentally appropriate. The same menu options can support both ring and oral PrEP users, though content should be tailored to the individual products.

Exploring user and stakeholder perspectives from South Africa and Uganda to refine microarray patch development for HIV PrEP delivery and as a multipurpose prevention technology. PLoS One 2023; 18:e0290568. [PMID: 37651432 PMCID: PMC10470907 DOI: 10.1371/journal.pone.0290568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 08/11/2023] [Indexed: 09/02/2023] Open
Abstract
BACKGROUND Oral HIV pre-exposure prophylaxis (PrEP) is highly effective, but alternative delivery options are needed to reach more users. Microarray patches (MAPs), a novel drug-delivery system containing micron-scale projections or "microneedles" that deliver drugs via skin, are being developed to deliver long-acting HIV PrEP and as a multipurpose prevention technology to protect from HIV and unintended pregnancy. We explored whether MAP technology could meet user and health system needs in two African countries. METHODS Researchers in South Africa and Uganda conducted 27 focus group discussions, 76 mock-use exercises, and 31 key informant interviews to explore perceptions about MAPs and specific features such as MAP size, duration of protection, delivery indicator, and health system fit. Participants included young women and men from key populations and vulnerable groups at high risk of HIV and/or unintended pregnancy, including adolescent girls and young women; female sex workers and men who have sex with these women; and men who have sex with men. In Uganda, researchers also recruited young women and men from universities and the community as vulnerable groups. Key stakeholders included health care providers, sexual and reproductive health experts, policymakers, and youth activists. Qualitative data were transcribed, translated, coded, and analyzed to explore perspectives and preferences about MAPs. Survey responses after mock-use in Uganda were tabulated to assess satisfaction with MAP features and highlight areas for additional refinement. RESULTS All groups expressed interest in MAP technology, reporting perceived advantages over other methods. Most participants preferred the smallest MAP size for ease of use and discreetness. Some would accept a larger MAP if it provided longer protection. Most preferred a protection duration of 1 to 3 months or longer; others preferred 1-week protection. Upper arm and thigh were the most preferred application sites. Up to 30 minutes of wear time was considered acceptable; some wanted longer to ensure the drug was fully delivered. Self-administration was valued by all groups; most preferred initial training by a provider. CONCLUSIONS Potential users and stakeholders showed strong interest in/acceptance of MAP technology, and their feedback identified key improvements for MAP design. If a MAP containing a high-potency antiretroviral or a MAP containing both an antiretroviral and hormonal contraceptive is developed, these products could improve acceptability/uptake of protection options in sub-Saharan Africa.

Abstract
Introduction With high concurrent global rates of HIV incidence and unintended pregnancy, there is a need to provide options beyond condoms to enable users to simultaneously prevent HIV acquisition and pregnancy. Multiple vaginal rings are in development as "MPTs" (multipurpose prevention technologies) as they are shown to provide several co-occurring benefits such as discretion, convenience, reversibility and user control. Methods In this Phase 1 trial of a 3-month MPT ring in the U.S., 25 participants (low-risk for HIV and pregnancy) were randomized to use the study ring for 90 days continuously or in 28-day cycles with 2-day removal periods in between. All participants completed in-depth interviews at the end of their study participation. Results Overall, the ring was well tolerated. Participants resoundingly endorsed the concept of an extended-use, dual-purpose vaginal ring, but reported too many functional challenges and side effects to endorse this particular ring. Participants assigned to the continuous regimen reported more positive experiences with ring use than those in the cyclic group. A minority of participants who experienced minimal side effects and did not experience challenges with vaginal retention of the ring found it appealing. However, the majority of participants experienced challenges (ring slippage, expulsions, side effects, vaginal bleeding changes) with product use that outweighed the potential benefits and led them to report that - in the future - they would not be interested in using this specific version of the ring in its current form. A subset expressed interest in using the current MPT ring under certain conditions (e.g., if fewer expulsions, less bleeding, higher risk for HIV/pregnancy). Discussion User feedback regarding participant experiences and challenges with the study ring was continuously shared with the product developer, underscoring the value of early-stage end-user feedback in product development.

Abstract
INTRODUCTION Adolescent girls and young women (AGYW) in sub-Saharan Africa are disproportionately affected by the HIV epidemic and face an array of challenges using proven behavioral and biomedical prevention methods. To address the urgent need for expanding prevention options, we evaluated the baseline preferences of HIV prevention methods among participants enrolled in the MTN-034/REACH crossover trial along with their stated product preference prior to product initiation. METHODS AGYW aged 16-21 years were enrolled at 4 study sites: Cape Town and Johannesburg, South Africa; Kampala, Uganda; and Harare, Zimbabwe and randomly assigned to the sequence of using oral PrEP and the dapivirine ring for 6 months each, followed by a choice period in which they could choose either product (or neither) for an additional six months. Eligible AGYW were HIV-negative, not pregnant and using effective contraception for at least two months prior to enrollment. Descriptive statistics were used to summarize demographic and behavioral data while multinomial analysis was used to determine predictors of stated product preference (ring or oral PrEP). RESULTS Of the 247 AGYW enrolled in REACH, 34% were aged 16-17 and 89% had a primary partner.The median age of sexual debut was 16 years and 40% had ever been pregnant. At screening, 35% of participants were diagnosed with a sexually transmitted infection (STI), 39% had an AUDIT-C score associated with harmful drinking and 11% reported intimate partner violence in the past 6 months. Overall, 28% of participants, had CESD-10 scores suggestive of depressive symptoms (≥12) in the past week. At baseline, similar proportions stated a preference for the ring and oral PrEP (38.1% and 40.5% respectively), with 19% of participants stating they preferred both products equally. Only study site was significantly associated with product preference (P<0.05) with AGYW from Johannesburg having higher odds of preferring the ring and those from Kampala having higher odds of preferring both options equally. CONCLUSIONS We successfully enrolled African AGYW with a clear unmet need for HIV prevention. The balanced preference between the two products suggests that multiple biomedical prevention options may be appealing to this age group and could address their prevention needs.

Abstract
HIV and gender-based violence (GBV) are syndemic in sub-Saharan Africa and provision of support for participants who disclose GBV constitutes part of comprehensive care. Consequently, a process was undertaken to develop, implement, and evaluate standard operating procedures (SOPs) in MTN-025/HOPE, a study of the dapivirine vaginal ring for HIV prevention. The SOP was developed using needs assessment surveys in addition to World Health Organization (WHO) guidelines and other literature. Sites tailored and implemented the SOP through HOPE implementation. At study end, staff reported increased training 32/35 (91.43%); improved confidence (18/26; 69.23%); and improved vicarious trauma prevention onsite (17/28; 60.71%). Leadership reported increased staff competence in GBV response. Obstacles included limited referral organizations and time for follow-up, continued training needs, and cultural norms. Development and implementation of an SOP is a feasible strategy to build a GBV response to improve health systems and support sustained effective use of HIV prevention products.

Abstract
IntroductionMost women face multiple and co-occurring risks from unwanted pregnancy, human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) at some point during their lifetime. While a range of contraceptive methods exist and options for HIV prevention are increasing, to date, only male and female condoms provide multipurpose protection from both pregnancy and disease.MethodsFrom September 2017 to December 2018, 60 women from the United States and the Dominican Republic, randomized 1:1 to continuous or interrupted use and 4:1 to active vs. placebo ring, participated in a Phase I trial to assess the safety and tolerability of a three-month multipurpose intravaginal ring (IVR) containing the antiviral tenofovir and the contraceptive levonorgestrel. This study examines survey responses from all participants and qualitative data from a subset of 17 women to assess acceptability of and preferences for IVR characteristics.ResultsOverall, women liked the concept of a multipurpose IVR and found it easy to insert and remove. Initial concerns about the size or thickness of the ring generally disappeared with use experience. Women weighed trade-offs between the ease of continuous use for a longer duration against concerns about hygiene and discoloration of the ring when left in place during menses. Whether randomized to continuous or interrupted use, most women found ring attributes (size, thickness, flexibility) very acceptable. They provided recommendations via survey and qualitative interviews for ring modifications that would further increase acceptability. Insights into women's use experiences also suggest the need for clear counseling messages and introduction strategies that can facilitate women's choice and use of prevention methods.DiscussionStudy findings suggest that a multipurpose IVR would make a valuable contribution to women's sexual and reproductive health options, and that both continuous and interrupted use strategies may be preferred.

Abstract
MTN-025/HOPE was an open-label trial of the dapivirine vaginal ring conducted in four African countries between 2016 and 2018. Women were first offered one ring monthly (at baseline, months 1 and 2), thereafter, transitioned to a more applicable real-world dispensation schedule, - 3 rings quarterly (at months 3, 6 and 9). Logistic regression analysis was used to assess correlates of ring acceptance at baseline and through follow-up. A total of 1456 women (median age 31 years) enrolled, 1342 (92.2%) accepted the ring at baseline and 1163 (79.9%) accepted the ring(s) at all visits. Changing ring dispensation from a monthly to a quarterly schedule had no negative effect on acceptance. Having a primary partner and him knowing about the ring being offered in HOPE, use of long-acting contraception (implants, injections, IUDs) or sterilization were associated with ring acceptance, along with prior strong intention to use the ring in the future. Efforts should consider these factors when rolling out the ring for HIV prevention.

Abstract
We reviewed the literature on the assessment of acceptability of HIV prevention and treatment interventions and service delivery strategies. Following PRISMA guidelines, we screened 601 studies published from 2015 to 2020 and included 217 in our review. Of 384 excluded studies, 21% were excluded because they relied on retention as the sole acceptability indicator. Of 217 included studies, only 16% were rated at our highest tier of methodological rigor. Operational definitions of acceptability varied widely and failed to comprehensively represent the suggested constructs in current acceptability frameworks. Overall, 25 studies used formal quantitative assessments (including four adapted measures used in prior studies) and six incorporated frameworks of acceptability. Findings suggest acceptability assessment in recent HIV intervention and service delivery research lacks harmonization and rigor. We offer guidelines for best practices and future research, which are timely and critical in this era of informed choice and novel options for HIV prevention and treatment.

Planning for decentralized, simplified prEP: Learnings from potential end users in Ga-Rankuwa, gauteng, South Africa. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 4:1081049. [PMID: 36699142 PMCID: PMC9868940 DOI: 10.3389/frph.2022.1081049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 12/16/2022] [Indexed: 01/12/2023] Open
Abstract
Background In South Africa, youth experience challenges with oral Pre-Exposure Prophylaxis (PrEP) access and uptake. Taking services out of healthcare settings has the potential to increase reach and overcome these challenges. This paper presents young and older people's preferences for decentralized, simplified PrEP service delivery and new long-acting HIV prevention methods, in Ga-Rankuwa, South Africa. Methods Between May and August 2021, both PrEP user and non-user adolescent girls and young women (AGYW), pregnant AGYW, female sex workers, adolescent boys and young men (ABYM), and men who have sex with men (MSM) were recruited to participate in focus group discussions (FDGs) in Ga-Rankuwa, Gauteng. Twenty-two FGDs were conducted. Participants were asked about PrEP uptake, potential acceptability of long-acting HIV prevention products, provision of integrated, simplified, and decentralized services, and digital tools to facilitate access to PrEP and other SRH services. A qualitative approach using inductive thematic analysis was carried out to explore emerging themes on decentralized, simplified delivery and the acceptability of long-acting methods. Results Of the 109 participants included in the study approximately 45% (n = 50) were female, the median age was 23 years ± 5.3. A third (n = 37) were current or previous PrEP users, of which, 59.5% (n = 22) collected PrEP refills from the clinic. Decentralized, simplified service delivery was appealing; health facilities, pharmacies and institutions of learning were preferred as service points for PrEP and SRH services, and recreational spaces preferred for dissemination of health information and engagement. ABYM were more open to having recreational spaces as service points. Long-acting Cabotegravir was preferred over the Dapivirine Vaginal Ring due to concerns around perceived side-effects, efficacy, and comfort. Conclusion Providing long-acting PrEP methods through decentralized, simplified service delivery was appealing to this population. They provided practical locations for decentralized service provision to potentially increase their engagement with and uptake of HIV prevention and SRH services.

Prospective acceptability of a multipurpose technology (MPT) implant in preclinical development to prevent HIV and unplanned pregnancy: Qualitative insights from women end users and health care providers in South Africa and Zimbabwe. PLoS One 2023; 18:e0285711.

Abstract
BACKGROUND Given the high rates of both HIV and unintended pregnancies in sub-Saharan Africa, the SCHIELD program aims to develop a multipurpose technology implant for HIV and pregnancy prevention. An end-user evaluation was undertaken with young women and health care providers to assess preferences for modifiable implant attributes to improve future adoption and rollout. METHODS Focus group discussions were conducted with potential women end users, and health care providers experienced in implant insertion or removal participated in in-depth interviews. All participants were recruited from Harare, Zimbabwe, or Soshanguve, South Africa. The purposively stratified sampled women were either implant experienced or implant naïve and were categorized into three groups: nulliparous, postpartum, or engaged in transactional sex. Topics covered included duration (six months to three years), biodegradability, removability, and independent rod retrievability (per indication). Data were analyzed using Dedoose software and summarized into emerging themes. RESULTS Participants identified three key areas that could facilitate rollout, uptake, and adherence of an implant for HIV and pregnancy prevention. First, discreetness was the most salient topic and was associated with implant characteristics such as anatomical location, flexibility, and biodegradability. Second, the ability to independently retrieve the HIV or pregnancy prevention component was preferred, as life circumstances may change and was favored by all participants, except for young women in Soshanguve. Third, there is a need for proper counseling, sensitization, provider training, and health campaigns to facilitate rollout of a 2-in-1 implant. CONCLUSIONS A 2-in-1 implant was seen as highly desirable by most young women and health care providers. Participants discussed potential concerns and barriers to uptake of a biodegradable implant with dual HIV prevention and contraceptive properties, identifying key implant attributes that product developers can modify while still in preclinical stages.

Women's experience receiving drug feedback and adherence counseling in MTN-025/HOPE - an HIV Prevention open-label trial of the Dapivirine Vaginal Ring. AIDS Behav 2022; 26:3607-3619. [PMID: 35536519 PMCID: PMC9561023 DOI: 10.1007/s10461-022-03663-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/18/2022] [Indexed: 11/01/2022]
Abstract
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.

Abstract
Multipurpose prevention technology intravaginal rings (MPT IVRs) may offer a promising solution for addressing women's multiple sexual and reproductive health needs. We describe MPT IVR acceptability perspectives and examine user experiences of 25 cisgender women aged 18-34 years enrolled in a phase IIa randomized, partially blinded, placebo-controlled evaluation of tenofovir-based IVRs with and without contraceptive co-formulation. All took part in an individual, audio-recorded, semi-structured qualitative interview. A thematic analysis of transcribed interviews was completed in MaxQDA. Participants shared little to no knowledge of or experience with IVRs prior to joining the study. Four MPT IVR themes were identified: physical well-being, method reliability, personal management, and societal endorsement. Commonly cited of concern, but less described as being experienced, were physical discomforts (e.g., painful insertion/removal; inability to carry out daily activities/chores; foreign body sensation; expulsion; sexual interference, or debilitating side effects). Uncertainty regarding efficacy influenced perspectives about intended prevention benefits. Personal choices in managing reproduction and sexual behaviors had to be congruent with sociocultural values and norms for acceptance beyond the individual user level. Participants viewed broader community acceptance as likely to be mixed given community opposition to the use of modern family planning methods. They also shared concerns that IVR use could lead to infertility, especially among nulliparous women, or that it would encourage premarital sex or high-risk sexual behaviors among adolescent and young women. While a MPT IVR may not be suitable for all women, first-hand testimonials could help influence collective receptivity. Additional community acceptability research is needed. Clinical Trial Registration The study is registered at http://ClinicalTrials.gov under the identifier NCT03762382.

Abstract
The dapivirine (DPV) vaginal ring was developed by the nonprofit International Partnership for Microbicides (IPM) for reducing the risk of HIV infection. A clinical study (IPM 028) showed that concomitant use of the DPV ring and miconazole (MIC) altered DPV pharmacokinetic profile. In this work, we investigated whether or not DPV transport and permeation contributed to the observed DPV-MIC interaction. Our study evaluated the interaction between DPV and several transporters that are highly expressed in the human female reproductive tract, including MRP1, MRP4, P-gp, BCRP, and ENT1, using vesicular and cellular systems. We also evaluated the impact of DPV/MIC on cellular tight junctions by monitoring transepithelial electrical resistance with the Ussing chamber. Lastly, we evaluated the effect of MIC on DPV permeability across human cervical tissue. Our findings showed that DPV was not a substrate of MRP1, MRP4, P-gp, BCRP, or ENT1 transporters. Additionally, DPV did not inhibit the activity of these transporters. DPV, MIC, and their combination also did not disrupt cellular tight junctions. MIC did not affect DPV tissue permeability but significantly reduced DPV tissue levels. Therefore, our results suggest that the DPV-MIC interaction is not due to these five transporters, altered tight junction integrity, or altered tissue permeability.

Abstract
HIV acquisition among pregnant and breastfeeding women in sub-Saharan Africa and vertical transmission rates remain high despite established strategies for HIV prevention. During the MTN-041/MAMMA study, we explored the influence of grandmothers (mothers and mothers-in-law of pregnant and breastfeeding women) in eastern and southern Africa on the health-related decisions of pregnant and breastfeeding women and their potential to support use of HIV prevention products. To do this we used structured questionnaires and focus group discussions with three stakeholder groups: 1) grandmothers, 2) HIV-uninfected currently or recently pregnant or breastfeeding women and 3) male partners of currently or recently pregnant or breastfeeding women. A total of 23 focus group discussions comprising 68 grandmothers, 65 pregnant or breastfeeding women and 63 male partners were completed across four study sites. Grandmothers were described as important sources of information during pregnancy and breastfeeding playing both supportive and influencer roles due to personal maternal experience and generational knowledge. While pregnant and breastfeeding women were not keen to involve grandmothers in HIV prevention decision making, they were accepting of grandmothers' involvement in a supportive role. Grandmothers expressed willingness to support pre-exposure prophylaxis use and agreed with the other two stakeholder groups that this decision should be made by women themselves or together with partners. These novel data indicate potential for grandmothers' health related supportive roles to be extended to support decision-making and adherence to biomedical HIV prevention options, and possibly contribute to the decline in HIV acquisition among pregnant and breastfeeding women in these communities.

Abstract
BACKGROUND Persistent use of HIV prevention methods can be a challenge, particularly for some younger women. The long-acting, discreet, woman-centric dapivirine vaginal ring offers promise as a prevention method with less user burden, which could support continued use. We assessed dapivirine vaginal ring use to understand adherence patterns and identify characteristics influencing patterns. SETTING Participants enrolled in South Africa in the MTN-020/ASPIRE randomized placebo-controlled trial. METHODS We used group-based trajectory modeling to identify clusters of participants with similar longitudinal patterns of adherence in the last year of participation and potential predictors of group membership. Women with at least 1 year of follow-up were included (n = 626). RESULTS Five adherence patterns were identified: (1) consistently high, 34%, (2) consistently moderate, 34%, (3) consistently low, 16%, (4) decreasing, 9%, and (5) increasing, 7%. Women younger than 22 years [adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI): 1.0 to 3.0], using an intrauterine device (AOR 3.3, 95% CI: 1.4 to 7.8) or oral contraceptives (AOR 3.9, 95% CI: 1.7 to 8.9), experiencing menses (AOR 1.8, 95% CI: 1.1 to 3.0), and who reported inconsistent condom use (AOR 1.8, 95% CI: 1.0 to 3.3) were more likely to be classified as consistently low compared to consistently high (referent). CONCLUSIONS Most South African women successfully persisted with a moderate or high level of use. Encouraging ring replacement with completion of menses may help to decrease concerns about hygiene and improve persistence. Associations between contraception and persistent low adherence suggest efforts may be needed to ensure contraceptive method choice does not interfere with ring use.

Abstract
BACKGROUND Given available effective biomedical and behavioral prevention and treatment interventions, HIV-related implementation research (IR) is expanding. The rapid generation and dissemination of IR to inform guidelines and practice has the potential to optimize the impact of the Ending the Epidemic Initiative and the HIV pandemic response more broadly. METHODS We leveraged a prior mapping review of NIH-funded awards in HIV and IR from January 2013 to March 2018 and identified all publications linked to those grants in NIH RePORTER through January 1, 2021 (n = 1509). Deduplication and screening of nonoriginal research reduced the count to 1032 articles, of which 952 were eligible and included in this review. Publication volume and timing were summarized; Kaplan-Meier plots estimated time to publication. RESULTS Among the 215 NIH-funded IR-related awards, 127 of 215 (59%) published original research directly related to the grant, averaging 2.0 articles (SD: 3.3) per award, largely in the early IR phases. Many articles (521 of 952, 55%) attributed to grants did not report grant-related data. Time from article submission to publication averaged 205 days (SD: 107). The median time-to-first publication from funding start was 4 years. Data dissemination velocity varied by award type, trending toward faster publication in recent years. Delays in data velocity included (1) time from funding to enrollment, (2) enrollment length, and (3) time from data collection completion to publication. CONCLUSION Research publication was high overall, and time-to-publication is accelerating; however, over 40% of grants have yet to publish findings from grant-related data. Addressing bottlenecks in the production and dissemination of HIV-related IR would reinforce its programmatic and policy relevance in the HIV response.

Abstract
Background: The monthly dapivirine vaginal ring provides partial protection against HIV, and a longer duration ring may reduce user burden and improve adherence. We examined acceptability and preference for 3-month versus 1-month rings for HIV-1 risk reduction in a phase 1 clinical trial. Materials and Methods: In Microbicide Trials Network-036/International Partnership for Microbicides 047, 49 HIV-negative participants aged 18-45 were randomized to one of two 3-month rings or the 1-month ring. Acceptability ratings were collected at enrollment, week 4, and study exit (week 13). At exit, ring preference was assessed quantitatively among all participants and a randomly selected subset of 24 participants completed in-depth interviews. Quantitative and qualitative findings were integrated to explore factors influencing acceptability and preference. Results: Acceptability of each ring was initially moderate and increased during the trial. Ratings were lower in the 3-month ring arms than the 1-month arm at each time point, including baseline. Most participants (34/47; 72%) preferred a 3-month ring at exit; however, this proportion was significantly lower within some subgroups characterized by site, education, race/ethnicity, and experiences with ring use. Qualitative interviews revealed reservations about hygiene and safety of the 3-month ring, including discomfort with use during menses, but these were usually outweighed by its increased convenience. Conclusions: Both ring durations were highly acceptable at study exit. Although most participants preferred a 3-month ring, preference was more divided in certain subgroups, highlighting the benefit of offering different duration options. Providing additional support to address concerns about hygiene and safety may improve acceptability of a 3-month vaginal ring.

Abstract
BACKGROUND Women in Africa face disproportionate risk of human immunodeficiency virus (HIV) acquisition, accounting for more than half of new infections in Africa and similarly face a disproportionate burden of sexually transmitted infections (STIs). Very high STI prevalence is being observed globally, especially among people taking pre-exposure prophylaxis (PrEP) for HIV prevention. Doxycycline post-exposure prophylaxis (dPEP) has been proposed as an STI prevention strategy to reduce chlamydia, syphilis, and possibly gonorrhea, and trials are ongoing among cisgender men who have sex with men (MSM) and transgender women who are taking PrEP in high-income settings. We designed and describe here the first open-label trial to determine the effectiveness of dPEP to reduce STI incidence among cisgender women. METHODS We are conducting an open-label 1:1 randomized trial of dPEP versus standard of care (STI screening and treatment and risk-reduction counseling without dPEP) among 446 Kenyan women aged ≥ 18 and ≤ 30 years old women taking PrEP. Women are followed for 12 months, with quarterly STI testing, treatment, and adherence counseling. The primary trial outcome will be the combined incidence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum, compared between the randomized groups. We will also assess dPEP acceptability, tolerability, safety, impact on sexual behavior, adherence, and occurrence of antimicrobial resistance (AMR) in N. gonorrhoeae and C. trachomatis isolates. Finally, we will estimate cost per incident STI case and complications averted accounting for nonadherence and benefits relative AMR or side effects. DISCUSSION The results of this trial may have immediate implications for the global epidemic of STIs and sexual health. If effective, dPEP could put STI prevention into women's hands. While dPEP may be able to prevent STIs, it carries important risks that could counter its benefits; global debate about the balance of these potential risks and benefits requires data to inform policy and implementation and our study aims to fill this gap.

Abstract
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.

The CHARISMA randomized controlled trial: a relationship-focused counseling intervention integrated within oral PrEP delivery for HIV prevention among women in Johannesburg, South Africa. J Acquir Immune Defic Syndr 2022; 90:425-433.

Abstract
BACKGROUND Consistent use of oral pre-exposure prophylaxis (PrEP) has been a challenge among women, particularly when in relationships with lack of partner support or intimate partner violence (IPV). Methods. We conducted a randomized controlled trial (RCT) of an empowerment counseling intervention called "CHARISMA" delivered to women within a PrEP demonstration project in Johannesburg, South Africa. The trial tested the effectiveness of CHARISMA to increase PrEP adherence; decrease social harms (SHs) and IPV; and improve partnership dynamics (e.g. communication, disclosure and support) as compared to those who received the standard of care (SOC) counselling support and referrals. 407 HIV-seronegative, non-pregnant women aged 18-45 years were enrolled for 6 months of PrEP use, with 203 randomized (1:1) to the intervention. All participants reporting IPV received counseling and referrals that followed the WHO five-step Listen, Inquire, Validate, Enhance Safety, and Support approach. Results. This RCT did not identify statistically significant differences between study arms for PrEP adherence or relationship dynamics, with the exception of an increase in PrEP disclosure among intervention arm women. In our study, we cannot determine whether the lack of detectable findings may have been due to lack of intervention effect, strength of SOC services, low risk in the study population or other factors. Conclusions: Addressing IPV and relationship dynamics remain important factors influencing HIV risk, and addressing these within the context of PrEP delivery is an important synergistic opportunity. CHARISMA was highly acceptable to participants, and further adaptation and testing of the intervention to other populations and settings will augment the evidence base.

Abstract
Vaginal rings address a critical need for an independently initiated, long-acting HIV prevention method, but their design must be acceptable to promote uptake and adherence. Human-centered design (HCD) may help address design preference questions. In two Phase I studies of vaginal rings for HIV prevention conducted in the United States, we used qualitative interviews to assess participants' perceptions and opinions of the physical characteristics of the ring they used and of a ring's physical characteristics after comparing four ring designs presented via a visual tool. Users were found to prefer ring designs that appear easy to use, are physically comfortable, that function well, and are aesthetically pleasing. The parameters for these features varied widely. Product developers and marketers should consider marketing messages in which the target users feel this product is made to meet their needs and desires. Product developers are encouraged to design using HCD early in ring development (Clinical Trial Registration number: NCT03234400 and NCT03670355).

Abstract
OBJECTIVE The vaginal ring (ring) is a female-initiated, long-acting drug delivery system for different indications, including HIV prevention. Our aim was to provide evidence for acceptability of the vaginal ring across indications to support dapivirine and multipurpose prevention technology ring introduction and roll out. STUDY DESIGN This systematic review and meta-analysis followed PRISMA guidelines. We searched PubMed, Web of Science, Embase, and grey literature for publications reporting favorable ring acceptability and secondary outcomes involving actual ring use (comfort, ease of ring use, ring comfort during sex, expulsions, and vaginal symptoms) or hypothetical acceptability for any indication published January 1, 1970-June 15, 2021. We estimated random-effects pooled prevalence, assessing between-study variation using meta-regression. RESULTS Of 2,234 records, we included 123 studies with 40,434 actual and hypothetical ring users. The primary outcome assessment included 50 studies with 60 ring subgroups totaling 19,271 ring users. The favorable acceptability pooled prevalence was 85.6% (95%CI 81.3, 89.0), while hypothetical acceptability among non-ring users was 27.6% (95%CI 17.5, 40.5). In meta-regression, acceptability was higher in menopause (95.4%; 95%CI 88.4, 98.2) compared to contraceptive rings (83.7%; 95%CI 75.6, 89.5). Acceptability was lower in pharmacokinetic studies (50%; 95%CI 22.1, 77.9) compared to RCTs (89.5%; 95%CI 85.8.92.4) and in studies assessing acceptability at ≥12 months (78.5%; 95%CI 66.5, 87.1) versus studies assessing acceptability at <3 months (91.9%; 95%CI 83.7, 96.1). European (90.6%; 95%CI 83.9, 94.7), Asian (97.1%; 95%CI 92.0, 99.0), and multi-region studies (93.5%; 95%CI 84.6, 97.4) reported more favorable acceptability compared to African studies (59.4%; 95%CI 38.3, 77.5). Secondary outcomes were similarly favorable, including ring comfort (92.9%; 95%CI 89.2, 95.4), ease of use (90.9%; 95%CI 86.5, 94.0), and comfort during sex (82.7%; 95%CI 76.4, 87.6). Limitations include inconsistent outcome definitions and unmeasured factors affecting acceptability. CONCLUSIONS Women who used vaginal rings reported they were acceptable across indications geographic regions and indications. Policy makers should consider the ring as an important option for pregnancy and HIV prevention drug development. IMPLICATIONS This review found favorable acceptability among vaginal ring users across indications and geographic areas, in contrast to low hypothetical acceptability among non-users. Vaginal rings are an important drug delivery system for pregnancy and HIV preventions, and scale-up should plan to address initial hesitancy among new users.

Abstract
INTRODUCTION Adolescent girls and young women (AGYW), as well as pre- and post-menopausal women globally would benefit from expanded choice to address their sexual and reproductive health (SRH) needs related to Human Immunodeficiency Virus (HIV), sexually transmitted infections (STIs) and pregnancy prevention. Lack of adequate preventative vaccines for HIV/STIs reinforces public health prioritization for options women may use independently to mitigate risk for infectious disease and unplanned pregnancy. Drug releasing intravaginal rings (IVR) represent one such technology that has garnered attention based on the modality's success recently as a pre-exposure prophylaxis (PrEP) delivery option and its impact on reduction in HIV risk. AREAS COVERED : This article provides a synopsis of three IVR technologies in active clinical development for prevention of HIV, STI, and unintended pregnancy demonstrating advancements in terms of compatibility with a wide range of drug types with a focus on dapivirine-based silicone rings (International Partnership for Microbicides (IPM), tenofovir-based polyurethane rings (CONRAD), and pod-based rings (Oak Crest Institute of Science). EXPERT OPINION The goals of IVR research are to reduce burdens of HIV/STIs and unplanned pregnancies. Through the evolution of IVR technologies, the potential exists to trigger integration of healthcare services through formulation of products with multiple indications.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
The development of potent antiretroviral drugs has significantly reduced morbidity and mortality associated with human immunodeficiency virus infection, however, the effectiveness of these medications depends upon consistent daily oral intake. Non-adherence can lead to the emergence of resistance, treatment failure and disease progression. This has necessitated the development of long-acting antiretroviral formulations administrable via an infrequent dosing regimen. Long-acting injectable forms of cabotegravir and rilpivirine have reached various stages in clinical trials both for the treatment and prevention of HIV. Other long-acting agents are at various stages of development. This review evaluates the current research on the development of long-acting injectable antiretroviral agents for the treatment and prevention of HIV.

Impact and experience of participant engagement activities in supporting dapivirine ring use among participants enrolled in the phase III MTN-020/ASPIRE study. BMC Public Health 2021; 21:2041.

Abstract
BACKGROUND Low adherence to investigational products can negatively impact study outcomes, limiting the ability to demonstrate efficacy. To continue advancing potential new HIV prevention technologies, efforts are needed to improve adherence among study participants. In MTN-020/ASPIRE, a phase III randomized, double-blind, placebo-controlled study of the dapivirine vaginal ring carried out across 15 sites in sub-Saharan Africa, a multifaceted approach to adherence support was implemented, including a strong focus on participant engagement activities (PEAs). In this manuscript, we describe PEAs and participant attendance, and analyze the potential impact of PEAs on ring use. METHODS All sites implemented PEAs and submitted activity and attendance reports to the study management team throughout the study. Participant demographics were collected via case report forms. Residual dapivirine remaining in the last ring returned by each participant was used to estimate drug released from the ring, which was then adjusted for time participants had the ring to calculate probable use categorized into three levels (low/intermittent/high). Product use was connected to PEA attendance using participant identification numbers. We used multivariate Poisson regression with robust standard errors to explore differences in ring use between PEA attendance groups and reviewed qualitative reports for illustrative quotes highlighting participant experiences with PEAs. RESULTS 2312 of 2629 study participants attended at least one of 389 PEAs conducted across sites. Participant country and partner knowledge of study participation were most strongly associated with PEA attendance (p < 0.005) with age, education, and income status also associated with event attendance (p < 0.05). When controlling for these variables, participants who attended at least one event were more likely to return a last ring showing at least some use (RR = 1.40) than those who never attended an event. There was a stronger correlation between a last returned ring showing use and participant attendance at multiple events (RR = 1.52). CONCLUSIONS 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 considered when designing future studies of investigational products.

Abstract
Understanding characteristics associated with adherence to pre-exposure prophylaxis (PrEP) methods for HIV-1 prevention may assist with optimizing implementation efforts. The dapivirine vaginal ring is a novel topical PrEP delivery method. Using data from a randomized, double-blind, placebo-controlled, phase III trial of the dapivirine vaginal ring conducted in four African countries, generalized estimating equation models were used to evaluate correlates of ring adherence. Two levels of quarterly dapivirine blood plasma, and dapivirine released from returned rings defined measures of adherence for recent and cumulative use, respectively. Time on study, calendar time, primary partner knowledge that the participant was taking part in the study, and use of long-acting contraceptive methods were associated with ring adherence whereas younger age, ring worries, condom use, episodes of menstrual bleeding and vaginal washing were associated with non-adherence. These findings may be useful for recruitment into future clinical studies and dapivirine ring implementation efforts.

Acceptability of the Dapivirine Vaginal Ring for HIV-1 Prevention and Association with Adherence in a Phase III Trial. AIDS Behav 2021; 25:2430-2440. [PMID: 33713213 PMCID: PMC8222015 DOI: 10.1007/s10461-021-03205-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/17/2021] [Indexed: 12/16/2022]
Abstract
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 nonadherence were estimated using Poisson regression models with robust standard errors. At month 3 (N = 2334), 88% reported DVR was comfortable, 80% were unaware of it during daily activities, and 74% never felt it during sex. At exit, 66% were ‘very likely’ to use DVR in the future. Acceptability was found to differ significantly by country across several measures including wearing the ring during sex, during menses, partner acceptability, impact on sexual pleasure and willingness to use the ring in the future. Risk of nonadherence at month 12 was elevated if DVR was felt during sex at month 3 (aRR 1.67, 95% CI 1.26, 2.23). Risk of nonadherence in the last year of study participation was elevated if, at exit, participants minded wearing during sex (aRR 2.08, 95% CI 1.52, 2.85), during menses (aRR 1.57, 95% CI 1.06, 2.32), reported a problematic change to the vaginal environment (aRR 1.57, 95% CI 1.12, 2.21), and were not “very likely” to use DVR in the future (aRR 1.31, 95% CI 1.02, 1.68). DVR acceptability was overall high yet varied by country. Addressing perceived ring interference with sex, menses, or problematic changes to the vaginal environment in future interventions could help improve adherence, as could embracing sex-positive messaging related to ring use and increased pleasure.

Abstract
OBJECTIVE This study aims to assess the product-related, relationship-related, and sex-related factors that act as facilitators and barriers to the acceptability of a vaginal ring (VR) for HIV prevention among adolescent girls. DESIGN Qualitative study. METHODS Ninety-six girls aged 15-17 years from 6 urban US sites were enrolled in MTN-023/IPM 030, a 24-week randomized controlled trial, for assessing the safety and acceptability of a dapivirine VR for HIV prevention. At week 24, 21 girls were randomly selected to participate in in-depth interviews. Interviews were transcribed verbatim and data analyzed using a thematic analysis approach. Facilitators and barriers to VR acceptability related to participants' relationships, sexual activity, and characteristics of the VR product were identified. RESULTS Factors related to relationships rarely seemed to act as barriers to VR acceptability; most participants disclosed VR use to sexual partners, and positive reactions from sexual partners, which were common, seemed to facilitate VR acceptability. Emotional and/or physical discomfort surrounding VR use during sex was mentioned occasionally as a barrier to VR acceptability. Product characteristics were most frequently mentioned as barriers to VR acceptability. Many participants reported concerns about the large size of the VR on first impression. Although most found the VR comfortable, some reported pain with VR insertion. Several participants were concerned about VR cleanliness, particularly during menstruation. CONCLUSION Product considerations, specifically size and use during menstruation, were the most commonly reported barriers to VR acceptability in this study. Adolescent girls may require additional counseling to assuage product concerns regarding a VR for HIV prevention.

Men's Sexual Experiences with the Dapivirine Vaginal Ring in Malawi, South Africa, Uganda and Zimbabwe. AIDS Behav 2021; 25:1890-1900. [PMID: 33389318 DOI: 10.1007/s10461-020-03119-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/07/2020] [Indexed: 01/20/2023]
Abstract
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.

Abstract
INTRODUCTION Vaginal rings are a promising approach to provide a woman-centred, long-acting HIV prevention strategy. Prior trials of a 25 mg dapivirine (DPV) ring have shown a favourable safety profile and approximately 30% risk reduction of HIV-1 infection. Extended duration rings replaced every three months may encourage user adherence, improve health service efficiency and reduce cost overall. We evaluated safety, pharmacokinetics, adherence and acceptability of two three-month rings with different DPV dosages, compared with the monthly DPV ring. METHODS From December 2017 to October 2018, MTN-036/IPM-047 enrolled 49 HIV-negative participant in Birmingham, Alabama and San Francisco, California into a phase 1, randomized trial comparing two extended duration (three-month) rings (100 or 200 mg DPV) to a monthly 25 mg DPV ring, each used over 13 weeks, with follow-up completed in January 2019. Safety was assessed by recording adverse events (AEs). DPV concentrations were quantified in plasma, cervicovaginal fluid (CVF) and cervical tissue, at nominal timepoints. Geometric mean ratios (GMRs) relative to the comparator ring were estimated from a regression model. RESULTS There were no differences in the proportion of participants with grade ≥2 genitourinary AEs or grade ≥3 AEs in the extended duration versus monthly ring arms (p = 1.0). Plasma and CVF DPV concentrations were higher in the extended duration rings compared to the monthly ring. Plasma GMRs were 1.31 to 1.85 and 1.41 to 1.86 and CVF GMRs were 1.45 to 2.87 and 1.74 to 2.60 for the 100 and 200 mg ring respectively. Cervical tissue concentrations were consistently higher in the 200 mg ring (GMRs 2.36 to 3.97). The majority of participants (82%) were fully adherent (ring inserted at all times, with no product discontinuations/outages) with no differences between the monthly versus three-month rings. Most participants found the ring acceptable (median = 8 on 10-point Likert scale), with a greater proportion of participants reporting high acceptability (9 or 10) in the 25 mg arm (73%) compared with the 100 mg (25%) and 200 mg (44%) arms (p = 0.01 and p = 0.15 respectively). CONCLUSIONS The extended duration DPV rings were well-tolerated and achieved higher DPV concentrations compared with the monthly DPV ring. These findings support further evaluation of three-month DPV rings for HIV prevention.

Use of simulated vaginal and menstrual fluids to model in vivo discolouration of silicone elastomer vaginal rings. INTERNATIONAL JOURNAL OF PHARMACEUTICS-X 2021; 3:100081.

Abstract
Vaginal rings releasing antiretrovirals – either alone or in combination with contraceptive progestins – are being developed for prevention of human immunodeficiency virus (HIV) transmission via vaginal sex. Following Phase I trials, significant discolouration was observed on the surface of investigational silicone elastomer antiretroviral-contraceptive matrix-type vaginal rings containing either 25 mg dapivirine or 200 mg dapivirine plus levonorgestrel. In this study, potential causes of the discolouration have been assessed in vitro using simulated vaginal and menstrual fluids (SVF and SMF, respectively) to model in vivo exposure. The fluid compositions also included hydrogen peroxide (H2O2), hydrogen peroxide plus a copper intrauterine device (IUD), or synthetic dyes (representing personal care and household cleaning products). No discolouration was observed for rings exposed to SVF + hydrogen peroxide (with or without an IUD). However, the SVF + dye compositions showed significant ring discolouration, with staining patterns similar to those observed with rings that had been exposed to highly-coloured personal care and household cleaning products during clinical trial use. Exposure of rings to SMF compositions invariably caused yellow surface discolouration, dark spotting and markings, similar to the staining patterns observed following clinical use. The darker marks on the ring surface were identified as blood debris derived from the SMF. The study indicates that surface discolouration of rings in vivo can be attributed to exposure to menstrual fluid or highly coloured personal care or household cleaning products. Discolouration of the rings was not associated with any specific safety risks for the user, though severe discolouration could potentially impact acceptability and adherence.

Abstract
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.

van der Straten A, Ryan JH, Reddy K, Etima J, Taulo F, Mutero P, Taylor J, Piper J, Musara P. Influences on willingness to use vaginal or oral HIV PrEP during pregnancy and breastfeeding in Africa: the multisite MAMMA study. J Int AIDS Soc 2021; 23:e25536. [PMID: 32524700 PMCID: PMC7287313 DOI: 10.1002/jia2.25536] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 03/25/2020] [Accepted: 04/15/2020] [Indexed: 12/15/2022] Open
Abstract
Introduction Women in sub‐Saharan Africa spend a substantial portion of their reproductive lives pregnant and/or breastfeeding (P/BF), yet they have limited options to prevent HIV during these maternal stages. In preparation for phase 3b prevention trials in P/BF women, we explored attitudes about using a vaginal ring or oral pills for pre‐exposure prophylaxis (PrEP), perceptions of HIV risk during P/BF and key influences on future PrEP use. Methods In 2018, we conducted 16 single‐sex focus group discussions (FGDs) with community‐ and clinic‐recruited HIV‐uninfected women, currently or recently P/BF, aged 18 to 40, and men with (currently or recently) P/BF partners, aged 18+. Participants completed a behavioural questionnaire, viewed an educational video and handled prototype placebo products. FGDs were conducted in local languages and transcribed, coded and analysed, using a socio‐ecological framework, for key influences on willingness to use products, HIV risk perceptions and opinions on product attributes. Results Of the 128 participants (65 women, 63 men) 75% lived with their partner and 84% had a child. Women reported the most important influencers when P/BF were partners, and all stated that health decisions when P/BF are typically made jointly (e.g. medication use; ante/postnatal and baby care). There was consensus that P/BF women are at high risk for HIV, primarily because of their partner’s infidelities, and new prevention options were welcomed. Participants valued multiple options and stated that woman’s personal preference would be key to product choice. Anticipated concerns about products included risk of miscarriage, impact on infant development, complications during delivery and adequate production or taste of breastmilk. Specific perceived disadvantages emerged for the ring (e.g. vaginal discomfort, difficulty inserting/removing) and for pills (e.g. nausea/vomiting) that may be exacerbated during pregnancy. Health care providers’ (HCPs) knowledge and approval of product use during P/BF was needed to mitigate anticipated fears. Conclusions Participants perceived pregnancy and breastfeeding as high HIV risk periods and valued new prevention options. HIV protection of the mother‐child dyad, safety of the baby, and ultimately, health of the family were paramount. Endorsement by HCPs and support from partners were key to future product acceptance. Participants recommended involving partners and HCPs in sensitization efforts for future trials.

Qualitative Perceptions of Dapivirine VR Adherence and Drug Level Feedback Following an Open-Label Extension Trial. J Acquir Immune Defic Syndr 2021; 86:e90-e96. [PMID: 33278181 PMCID: PMC7902420 DOI: 10.1097/qai.0000000000002590] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 11/20/2020] [Indexed: 01/13/2023]
Abstract
BACKGROUND There continues to be a need for HIV prevention options that women can initiate and use autonomously. The dapivirine vaginal ring (VR) has been shown to have a favorable safety profile and reduce the risk of HIV-1 acquisition. We report on women's experiences with VR adherence during the MTN-025/HIV Open-label Prevention Extension (HOPE) study and responses to Residual Drug Level (RDL) results. SETTING 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 randomly selected (n = 60). METHODS After confirmation of eligibility criteria, in-depth interviews were conducted where available RDL results were presented. RESULTS Many women with low RDL release measurements deflected blame onto other factors (the ring, the drug, and faulty testing machines) and distrust of the testing method. The disclosure of RDL results enabled some users to discuss their challenges experienced (fear of partner objections, perceived side effects, and removals during menses). Consistent users reported important motivators (support from others, protection from HIV, and enhanced sexual experiences from the VR). CONCLUSION The VR provided a sense of security for some women; however, adherence was still challenging for others regardless of it being a female controlled, long-acting HIV prevention technology. Adherence measurements may not be sustainable in the real-world implementation of the VR, although they can be seen as a benefit as they provide a better understanding of actual product use and provide women with a platform to discuss their experiences.

Abstract
INTRODUCTION Vaginal ring delivery of antiretroviral drugs may provide protection against acquisition of HIV-1 when used as Pre-Exposure prophylaxis. As part of a randomized placebo-controlled safety trial of a tenofovir disoproxil fumarate (TDF) intravaginal ring (IVR), we assessed product acceptability through surveys of women after continuous ring use. METHODS Sexually active, HIV-negative women were enrolled to investigate the safety and pharmacokinetics of 3 months of continuous TDF IVR use. The study was designed to include 40 US participants randomly assigned (3:1) to a TDF or placebo IVR. Twelve were randomized to TDF and 5 to the placebo group before the study was electively discontinued because of the development of vaginal ulcerations in 8 women in the TDF group. Acceptability data were gathered via self-administered, computer-based questionnaires. RESULTS The average age of the 17 participants was 31 years (range, 18-42 years). Sixteen participants (94%) completed all questions at 2 study visits. When asked about ring likeability after 1 month of ring use, 12 (75%) of 16 reported overall liking the ring, including 6 (75%) of 8 who developed ulcerations. In addition, 10 (83%) of 12 who had their menses during the first month of ring use were not bothered by the ring, and 11 (69%) of 16 stated that the ring was not bothersome with use during sex. CONCLUSIONS Despite unanticipated ulcers, TDF and placebo IVRs were acceptable to some women, even when used with menses and during sex, which is promising for continued development of IVRs for HIV prevention.

Motivations to use hormonal contraceptive methods and condoms among HIV-positive and negative women randomized to a progestin contraceptive in Malawi: a qualitative study. BMC WOMENS HEALTH 2021; 21:114. [PMID: 33743659 PMCID: PMC7981805 DOI: 10.1186/s12905-021-01236-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 02/22/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Although many countries have been promoting hormonal contraceptives to prevent unintended pregnancy and condom use to prevent HIV transmission, little is known about how women targeted by these messages have interpreted and internalized them. We describe HIV-positive and negative women's understanding of the benefits of contraception and condoms and their motivations to use them. METHODS This is a qualitative sub-study from a clinical trial evaluating the effects of progestin contraception on HIV-positive and negative women aged 18-45 years randomly assigned to depot medroxyprogesterone acetate (DMPA) injection or levonorgestrel (LNG) implant. We purposively recruited 41 women to participate in in-depth interviews (IDIs) and focus group discussions (FGDs) after randomization into the main study. We conducted a total of 30 IDIs and 6 FGDs comprised of 4-7 women (N = 32). All women were counselled about potential risks for HIV acquisition/transmission with progestin-only contraception, drug-drug interactions between the implant and efavirenz-based ART, and the need to use condoms with their assigned contraceptive to help prevent pregnancy and HIV acquisition and transmission. RESULTS All women understood that HIV is transmitted through unprotected sex and that HIV transmission can be prevented through condom use but not DMPA injection or LNG implant use. Nearly all HIV-positive women knew or suspected that their partners were also HIV-positive and were most interested in using condoms to prevent infection with a drug-resistant HIV strain to keep their HIV viral load low. Almost all reported that their partners agreed to condom use, but few used them consistently. Most women believed that condoms were effective at preventing both HIV and pregnancy if used consistently. Nearly all women considered contraception and condom use as important in preventing unintended pregnancy and HIV because partner disclosure of HIV status is low. CONCLUSION Our results showed that both HIV-positive and negative women understood modes of HIV transmission and prevention and were aware that hormonal contraceptives are only effective for preventing pregnancy and not HIV. Although both HIV-negative and positive women were motivated to use condoms to prevent both HIV acquisition and infection with other HIV strains respectively, they all faced challenges from their partners in using condoms consistently.

Abstract
Antiretroviral drug therapy has significantly improved the prognosis and life expectancy of people living with HIV over the years. But this progress comes with an important caveat that antiretroviral regimens generally require adherence to life-long, daily dosing, to keep viral multiplication under check. Non-adherence to such dosing leads to decreased efficacy and increased drug resistance against antiretroviral drugs. Besides, poor drug penetration to certain tissues like CNS and lymph nodes leads to the build-up of viral reservoirs in these sites. To combat some of these challenges and improve patient compliance, long-acting antiretroviral drugs, are a new weapon in the arsenal, in the fight against HIV. Few long-acting preparations have been approved, and several others are in various clinical and preclinical stages of development. However, long-acting formulations also have their share of clinical issues like limited drug distribution, long term adverse drug reactions, drug-drug interactions, and gradual development of drug resistance. Modern technological premises are being tested to mitigate some of these problems. One such promising approach involves nanotechnological methods, which are being used to develop ultra-long acting formulations and drug delivery systems, targeting tissues with residual HIV concentration. Long-Acting Slow Effective Release Antiretroviral Therapy aka LASER ART, also builds on nanotechnology and prodrug modifications to design preparations with tailor-made favorable pharmacokinetics and wider drug distribution. These recent advances are fueling the progression of antiretroviral therapy towards eliminating the disease.
