[PMID: 38771970 DOI: 10.1080/09540121.2024.2354207] [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: 10/06/2023] [Accepted: 05/07/2024] [Indexed: 05/23/2024]
Abstract
This study aimed to measure the pooled estimate of willingness to use HIV pre-exposure prophylaxis (PrEP) (WTUP) among PrEP-naïve United States (U.S.)-based men who have sex with men (MSM). PubMed, Embase, Web of Science, CINAHL, and PsycINFO were searched. The search strategy contained the keyword willingness and interest and the MeSH terms for HIV and PrEP. Articles were included if they were published between January 2005 and May 2022, reported quantitative data on WTUP among PrEP-naïve US-based MSM, and were available as full text in English. Meta-analysis was conducted to assess the pooled effect size of WTUP prevalence using a random-effects model, heterogeneity in the pooled estimate was assessed, and subgroup analyzes were conducted. Fifteen studies were included based on the inclusion and exclusion criteria. Meta-analysis revealed a pooled prevalence proportion for WTUP of 0.58 (95% CI 0.54-0.61) (or 58 out of 100) among PrEP-naïve MSM. High inter-study heterogeneity (Q = 548.10, df = 19, p < 0.01, I2 = 96.53, τ2 = 0.09) was observed. Age of the study sample and region where the data were collected significantly moderated the pooled WTUP estimate. Age-appropriate PrEP related messaging and a focus on HIV priority areas of the U.S. would be important strategies to improve WTUP among MSM in the U.S. moving forward.

[PMID: 38713631 DOI: 10.1080/09540121.2024.2307378] [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: 07/18/2023] [Accepted: 01/10/2024] [Indexed: 05/09/2024]
Abstract
Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) is efficacious in preventing HIV among men-who-have-sex-with-men (MSM) and will be soon available in Europe. This study investigated the intention and preference to use LAI-PrEP among MSM in the Netherlands by employing a diffusion of innovation approach. This study had a cross-sectional design nested within a cohort study established in 2017 to understand oral PrEP use among MSM. 309 MSM completed the survey on their awareness, interest, intention, and preference for LAI-PrEP in June 2022. Among them, 83% showed high/very-high interest in, and 63% showed high/very-high intention to use LAI-PrEP. A repeated innovator effect from the early adopters to LAI-PrEP was not observed. Early adopters did not show increased intention to use LAI-PrEP compared to other MSM subgroups, but neither did PrEP-naïve nor PrEP-discontinued MSM. However, among the 218 current oral PrEP users, suboptimal adherence was associated with preference for LAI-PrEP but not with intention to use it. In conclusion, our findings indicated that an effective, available, and affordable LAI-PrEP would be welcomed in the Netherlands, but that its introduction may not significantly expand PrEP coverage. However, the introduction of LAI-PrEP in the Netherlands could prove beneficial to MSM with suboptimal adherence to oral PrEP.

Abstract
BACKGROUND HIV pre-exposure prophylaxis (PrEP) is a highly effective method to mitigate the HIV epidemic, but uptake of PrEP has been slow and is associated with racial and gender disparities. Oral PrEP requires high levels of adherence to be effective, which may disadvantage certain high-risk groups. The first injectable HIV PrEP, a drug given every 2 months rather than as a daily pill, was approved by the US Food & Drug Administration in December 2021. SETTING A Family Medicine practice in a single health organization in the United States (November 2022 to February 2023). METHODS We conducted interviews with patients and key stakeholders to characterize factors affecting long-acting injectable (LAI) PrEP implementation. Data collection and analysis were guided by the Consolidated Framework for Implementation Research. Interviews were transcribed and analyzed using guided content analysis. RESULTS Twenty-five patients (n = 13) and practice stakeholders (n = 12) were interviewed. Overall, stakeholders described a very low uptake of LAI PrEP. Barriers to LAI PrEP included a lack of awareness, insurance and access issues, a lack of streamlined workflow, and a trust in pills over injectables. Facilitators to LAI PrEP implementation included the absence of a pill burden, a culture of shared decision making, and pharmacy support. CONCLUSIONS Although uptake has been slow, we have identified several promising strategies for improving rollout and implementation of LAI PrEP. Approaches that can bolster rollout of LAI PrEP include having an interdisciplinary care team that is supported by PrEP navigators and pharmacists and are informed by a patient-centered model of care to increase patient engagement and trust.

[PMID: 38526639 DOI: 10.1007/s10461-024-04314-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/04/2024] [Indexed: 03/27/2024]
Abstract
In December 2021, long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was approved for the prevention of HIV in at-risk adults and adolescents. LAI-PrEP may address adherence issues of daily oral daily PrEP and PrEP stigma. However, studies assessing LAI-PrEP willingness among PrEP naive Black and Hispanic sexual and gender minority (SGM) persons- a group disproportionately impacted by the HIV epidemic in the United States - is rare. To assess the extent of and characteristics of willingness to use LAI-PrEP in a national sample of Black and Hispanic SGM who are self-reported that they have never used PrEP. We analyzed data from a national sample of Black and Hispanic SGM collected between March and August 2020. We used log-binomial regression models to assess characteristics associated with willingness to use LAI-PrEP. Of the overall sample (N = 380), the mean age was 24 (SD = 2.8) and the majority of the sample (54%, n = 205) reported willingness to use LAI-PrEP. In multivariable log-binomial regression models, PrEP stigma was independently associated with less [prevalence ratio (PR) = 0.7, 95% confidence interval (CI) = 0.6, 0.9], while number of sexual partners in the past 12 months was associated with a more willingness to use LAI-PrEP (PR = 1.1, 95% CI = 1.0, 1.2). Our findings highlight the persistence of PrEP stigma as a potential barrier to willingness to use LAI-PrEP in this sample of Black and Hispanic SGM who have never used PrEP. Additional work needs to be done to reduce PrEP stigma more broadly.

Factors influencing the uptake of a mono-PrEP implant for the prevention of HIV: Males' perspectives from three South African provinces. PLoS One 2024; 19:e0296341. [PMID: 38166044 PMCID: PMC10760848 DOI: 10.1371/journal.pone.0296341] [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: 07/06/2023] [Accepted: 12/11/2023] [Indexed: 01/04/2024] Open
Abstract
INTRODUCTION Oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention method; however, males over 15 years face challenges with its effective use. Long-acting prevention products could address barriers to effective PrEP use. This study aimed to estimate the potential uptake of a mono-PrEP implant and the factors influencing uptake among males in South Africa. The study also examined messaging and demand creation tactics that males perceive will improve HIV prevention uptake. METHODS We conducted a mixed methods study comprising participatory workshops and a self-administered survey among 142 PrEP-eligible males (18-40 years) in three provinces (Gauteng, Eastern Cape, and Kwa-Zulu Natal) in South Africa from July to November 2022. Logistic regression was used to assess the relationship between the potential uptake of a hypothetical, non-biodegradable mono-PrEP implant and socioeconomic and behavioural factors. Workshop data were analysed using content analysis. RESULTS The top three HIV prevention products that males would consider using were the monthly pill (74.6%), the mono-PrEP implant (62.7%), and event-driven oral PrEP (59.2%). If one prevention option was available, 31.7% of participants stated that they would use the monthly oral pill, 28.2% would use the six-monthly injection, and 19.7% the mono-PrEP implant. Four key themes were noted as influential to potential mono-PrEP uptake: "Health Over Everything", "Mono-PrEP Implant Concerns", "Potential Disclosure of Mono-PrEP Use", and "Information Distribution Channels". Participants preferred social and mainstream media as information distribution channels to receive information on HIV prevention services, including the mono-PrEP implant. CONCLUSION In this study among predominantly heterosexual men in South Africa, there was interest in long-acting HIV prevention methods but concerns about the mono-PrEP implant. A comprehensive and participatory introduction will be needed for the implant, to improve acceptability and address potential concerns. Demand-creation strategies utilising social media and health campaigns should be considered to engage and reach males.

Preference for long-acting injectable for ART and PrEP among people with and without HIV: a cross-sectional study in Argentina. Ther Adv Infect Dis 2024; 11:20499361241228341. [PMID: 38380160 PMCID: PMC10878205 DOI: 10.1177/20499361241228341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 01/09/2024] [Indexed: 02/22/2024] Open
Abstract
Background Little is known about the preferences for antiretroviral therapy (ART) administration methods, such as oral daily pills or long-acting injectable (LAI) options, as well as preferences for pre-exposure prophylaxis (PrEP) administration methods among people without HIV in Latin America. Objectives This study aimed to assess the preferences for ART administration methods among people with HIV and PrEP methods among those without HIV, as well as to examine the correlations and reasons for these preferences. Design We conducted a cross-sectional web-based questionnaire between April and July 2021, using social media accounts of a HIV non-governmental organization. The questionnaire was open to all adults living in Argentina, irrespective of their sexual orientation or gender identity. Methods The questionnaire included questions on substance use, depression, chronic treatment, previous experiences with injectable medication, and HIV status. Those with HIV answered questions about ART adherence and their preferences for ART methods, while those without HIV were asked about condom use, awareness of PrEP, and their preferences for PrEP methods. Results Out of 1676 respondents, 804 had HIV, and 872 did not. Among those with HIV, 91.5% expressed a high preference for LAI-ART, with significantly higher preferences among participants with higher educational levels, cisgender gay, bisexual, and queer men, younger individuals, and those with prior injectable medication experience. Among those without HIV, 68% preferred LAI-PrEP, and this preference was positively associated with previous positive experiences with injectable medication. Conclusion The strong preference for LAI-ART suggests the potential for improved adherence and well-being among people with HIV. Additionally, the preference for LAI-PrEP among those without HIV emphasizes the importance of considering this option for HIV prevention strategies. This study highlights the need to offer diverse methods for ART and prevention to accommodate different preferences and improve health care outcomes in Latin America.

Abstract
INTRODUCTION Evidence on the willingness of men who have sex with men (MSM) with oral pre-exposure prophylaxis (PrEP) experience, especially those with suboptimal adherence, to take long-acting injectable PrEP (LAI-PrEP) is critical to guide future LAI-PrEP implementation. OBJECTIVE The objective was to assess the willingness of MSM with oral PrEP experience to take LAI-PrEP. METHODS MSM who participated in the China Real-world Study of Oral PrEP (CROPrEP) were enrolled in this study. Information on the willingness of MSM to take LAI-PrEP and potential correlates was collected using a structured online questionnaire. The main outcomes were the willingness of MSM to take LAI-PrEP and its association with HIV-related behaviours, sexually transmitted infections, and oral PrEP history. Logistic regression was used to identify correlates of the willingness of MSM to take LAI-PrEP. RESULTS A total of 612 former CROPrEP participants (FCPs) were included in this study. There were 315 (51.5%) daily oral PrEP (D-PrEP) users and 297 (48.5%) event-driven oral PrEP (ED-PrEP) users at the last follow-up. Most FCPs (77.8%) were willing to take free LAI-PrEP. FCPs with no less than two sexual male partners (aOR = 1.54, [95% CI: 1.04, 2.29], P = 0.031), those with male partners with unknown HIV statuses (aOR = 2.04, [95% CI: 1.31, 3.18], P = 0.002), those with recreational drug use (aOR = 1.58, [95% CI: 1.05, 2.40], P = 0.030), and those with HSV-2 positivity (aOR = 2.15, [95% CI: 1.30, 3.57], P = 0.003) were more willing to take LAI-PrEP, while ED-PrEP users (aOR = 0.66, [95% CI: 0.45, 0.98], P = 0.037) and FCPs with suboptimal oral PrEP adherence (aOR = 0.58, [95% CI: 0.36, 0.94], P = 0.026) were less willing to take LAI-PrEP. CONCLUSION LAI-PrEP has good prospects for expanding PrEP coverage. However, FCPs with suboptimal oral PrEP adherence are less likely to take LAI-PrEP. Further intervention and implementation efforts are needed to improve the willingness of MSM to use LAI-PrEP, and sexual health should be considered during the discussion about PrEP initiation.

Willingness to use long-acting injectable PrEP among HIV-negative/unknown men who have sex with men in mainland China: A cross-sectional online survey. PLoS One 2023; 18:e0293297. [PMID: 37856527 PMCID: PMC10586652 DOI: 10.1371/journal.pone.0293297] [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: 05/09/2023] [Accepted: 10/09/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND Men who have sex with men (MSM) are at high risk of HIV acquisition. Long-acting injectable-pre-exposure prophylaxis (LAI-PrEP), requiring less frequent dosing, is being studied as an alternative method to daily oral HIV PrEP. With the addition of this potential new prevention method, it expands the scope for a wider user choice and is expected to increase the acceptability and uptake of HIV prevention measures. The aim of our study was to explore the willingness to use LAI-PrEP and associated influential factors. METHODS Participants were recruited from December 2020 to March 2021 through banner advertisements on web- and mobile app-based platforms on Blued, a large gay Chinese social media platform. MSM in our cross-sectional study was HIV-negative and currently lived in mainland China. Participants were asked about their willingness to use LAI-PrEP and reasons why they might be or not be willing to use LAI-PrEP. Multivariable logistic regression was used to analyze the factors associated with the willingness to use LAI-PrEP. RESULTS In total, 969 participants met the inclusion criteria and finished the survey. Nearly twenty percent (19.5%) of participants had never tested for HIV; 66.8% of MSM had multiple male partners; and 51.6% of MSM engaged in condomless sex with their partner. About three-fifths (66.3%) of MSM were aware of PrEP, and only 3.9% of MSM had used PrEP before. The willingness to use LAI-PrEP among MSM was 74.0% (95% CI: 71.4%-76.6%). MSM with higher education levels were less likely to show a willingness to use LAI-PrEP (AOR = 0.56, 95%CI: 0.38-0.84). Participants who had a history of HIV test (AOR = 1.68, 95%CI: 1.11-2.55), were willing to use daily oral PrEP (AOR = 10.64, 95%CI:7.43-15.21), had multiple male sexual partners (AOR = 1.33, 95%CI:0.93-1.90), who used rush popper(AOR = 1.49, 95%CI:1.05-2.13), and who were aware of PEP (AOR = 1.66, 95%CI: 1.02-2.70) were more likely to show willingness to use LAI-PrEP. CONCLUSIONS In our study, MSM had quite high awareness but low uptake of PrEP. As LAI-PrEP is expected to be approved for use in China in the future, our study of MSM highlights the need for key population-focused education programs about PrEP and healthy sexual behavior. This study also provides some evidence for LAI-PrEP use among the Chinese MSM population in the future.

Ullah Nayan M, Sillman B, Hasan M, Deodhar S, Das S, Sultana A, Thai Hoang Le N, Soriano V, Edagwa B, Gendelman HE. Advances in long-acting slow effective release antiretroviral therapies for treatment and prevention of HIV infection. Adv Drug Deliv Rev 2023; 200:115009. [PMID: 37451501 DOI: 10.1016/j.addr.2023.115009] [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: 04/24/2023] [Revised: 06/21/2023] [Accepted: 07/12/2023] [Indexed: 07/18/2023]
Abstract
Adherence to daily oral antiretroviral therapy (ART) is a barrier to both treatment and prevention of human immunodeficiency virus (HIV) infection. To overcome limitations of life-long daily regimen adherence, long-acting (LA) injectable antiretroviral (ARV) drugs, nanoformulations, implants, vaginal rings, microarray patches, and ultra-long-acting (ULA) prodrugs are now available or in development. These medicines enable persons who are or at risk for HIV infection to be treated with simplified ART regimens. First-generation LA cabotegravir, rilpivirine, and lenacapavir injectables and a dapivirine vaginal ring are now in use. However, each remains limited by existing dosing intervals, ease of administration, or difficulties in finding drug partners. ULA ART regimens provide an answer, but to date, such next-generation formulations remain in development. Establishing the niche will require affirmation of extended dosing, improved access, reduced injection volumes, improved pharmacokinetic profiles, selections of combination treatments, and synchronization of healthcare support. Based on such needs, this review highlights recent pharmacological advances and a future treatment perspective. While first-generation LA ARTs are available for HIV care, they remain far from ideal in meeting patient needs. ULA medicines, now in advanced preclinical development, may close gaps toward broader usage and treatment options.

Systematic review of the values and preferences regarding the use of injectable pre-exposure prophylaxis to prevent HIV acquisition. J Int AIDS Soc 2023; 26 Suppl 2:e26107. [PMID: 37439057 PMCID: PMC10805120 DOI: 10.1002/jia2.26107] [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: 10/18/2022] [Accepted: 05/04/2023] [Indexed: 07/14/2023] Open
Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) is an important HIV prevention option. Two randomized trials have provided efficacy evidence for long-acting injectable cabotegravir (CAB-LA) as PrEP. In considering CAB-LA as an additional PrEP modality for people at substantial risk of HIV, it is important to understand community response to injectable PrEP. We conducted a systematic review of values, preferences and perceptions of acceptability for injectable PrEP to inform global guidance. METHODS We searched nine databases and conference websites for peer-reviewed and grey literature (January 2010-September 2021). There were no restrictions on location. A two-stage review process assessed references against eligibility criteria. Data from included studies were organized by constructs from the Theoretical Framework of Acceptability. RESULTS We included 62 unique references. Most studies were observational, cross-sectional and qualitative. Over half of the studies were conducted in North America. Men who have sex with men were the most researched group. Most studies (57/62) examined injectable PrEP, including hypothetical injectables (55/57) or placebo products (2/57). Six studies examined CAB-LA specifically. There was overall interest in and often a preference for injectable PrEP, though there was variation within and across groups and regions. Many stakeholders indicated that injectable PrEP could help address adherence challenges associated with daily or on-demand dosing for oral PrEP and may be a better lifestyle fit for individuals seeking privacy, discretion and infrequent dosing. End-users reported concerns, including fear of needles, injection site pain and body location, logistical challenges and waning or incomplete protection. DISCUSSION Despite an overall preference for injectable PrEP, heterogeneity across groups and regions highlights the importance of enabling end-users to choose a PrEP modality that supports effective use. Like other products, preference for injectable PrEP may change over time and end-users may switch between prevention options. There will be a greater understanding of enacted preference as more end-users are offered anti-retroviral (ARV)-containing injectables. Future research should focus on equitable implementation, including real-time decision-making and how trained healthcare providers can support choice. CONCLUSIONS Given overall acceptability, injectable PrEP should be included as part of a menu of prevention options, allowing end-users to select the modality that suits their preferences, needs and lifestyle.

Abstract
The recent approval of long-acting injectable cabotegravir (CAB-LA) as PrEP for HIV prevention could be an attractive alternative for MSM, particularly among those who face barriers to adherence using the oral pill. This study reports on the awareness of long-acting injectable PrEP (LAI-PrEP) and factors associated with interest in LAI-PrEP use among a nationwide sample of MSM in Malaysia. An online cross-sectional survey was conducted between August and September 2021 to explore perspectives on PrEP modalities among Malaysian MSM (N = 870). Convenience sampling was used to recruit participants using ads on two platforms hornet and facebook. While only 9.1% of the study participants were aware of LAI-PrEP, the majority had heard of oral PrEP (80.9%). After giving a description of it, a large majority (86.6%) expressed interest in using it if made accessible. Those who had a prior history of HIV testing (aOR = 1.9; 95% CI = 1.2-3.2) were more likely to use LAI-PrEP. Interestingly, despite the concerns related to potential high cost (aOR = 3.4; 95% CI = 2.1-5.5) and long-term side effects (aOR = 1.9; 95% CI = 1.2-3.1), the majority of the participants were interested in using LAI-PrEP. Those who were afraid of (or disliked) syringes were less interested in using it (aOR = 0.2; 95% CI; 0.1-0.4). In the recent context that LAI-PrEP was shown to be safe and effective at preventing HIV, our results indicate its potential relevance as an additional PrEP option that could accelerate the uptake and scale-up of PrEP. However, it is crucial to conduct future research urgently to improve the understanding of strategies that could enhance the accessibility, acceptability, and affordability of LAI-PrEP for MSM in low- and middle-income countries, including Malaysia.

Abstract
One hope surrounding long-acting HIV pre-exposure prophylaxis (PrEP) is reaching new users who could most benefit, as well as improving the experiences of oral PrEP users who may desire to switch modalities. Gay, bisexual, queer, and other men who have sex with men (GBQM) continue to make up over half of new HIV diagnoses in Canada, and oral PrEP uptake has plateaued among this population. Approval of injectable PrEP is anticipated, but there is a paucity of research to inform health promotion and implementation. Between June and October 2021, we conducted 22 in-depth interviews with GBQM oral PrEP users and non-PrEP users living in Ontario, Canada. We also conducted small focus groups or individual interviews with 20 key stakeholders (health care providers, public health officials, community-based organization staff). Interviews were audio recorded, transcribed verbatim, and analyzed in NVivo using thematic analysis. Only about one-third of GBQM had heard of injectable PrEP. Many PrEP users perceived greater convenience, adherence, and confidentiality with injectable PrEP. Some PrEP users did not anticipate switching because of needle discomfort or feeling more "in control" with oral PrEP. None of the non-PrEP users said that injectable PrEP would make them start PrEP. Injectable PrEP may offer additional convenience for GBQM; however, it did not appear to affect participants' PrEP decision-making significantly. Stakeholders noted that injectable PrEP may improve access, support adherence, and benefit marginalized groups. Some clinicians expressed concerns about the time/personnel required to make injectable PrEP available. System-level challenges in implementing injectable PrEP, including cost, must also be addressed.

Abstract
Intimate partner violence (IPV) is common in men who have sex with men (MSM). MSM also face increased risk of human immunodeficiency virus infection. However, it is not known whether IPV experience of MSM in China would affect their attitudes toward pre-exposure prophylaxis (PrEP) use. A cross-sectional study was conducted to explore the associations between different types of IPV and willingness to use PrEP in a sample of 608 MSM from November 2018 to May 2019 in Chengdu, China. Univariate and multivariate logistic regression analyses were used to explore the associations between different types of IPV and willingness to use PrEP. The average age of the participants was 31.8 ± 12.3 years, 48.9% of them were aware of PrEP before this study, and only 7.2% were aware of long-acting injectable PrEP (LAI-PrEP). The overall willingness to use any type of PrEP in the next 6 months was 82.2%. Approximately one third of the participants (n = 198) had experienced at least one type of IPV. We found that experience of sexual perpetration was negatively associated with the willingness to use on-demand PrEP (adjusted odds ratio [ORa] = 0.33, 95% CI = 0.16-0.67) and the overall willingness to use any type of PrEP (ORa = 0.31, 95% CI = 0.15-0.64). The willingness to use LAI-PrEP also had negative associations with any type of monitoring IPV (ORa = 0.58, 95% CI = 0.38-0.91), controlling victimization (ORa = 0.41, 95% CI = 0.21-0.82), and emotional victimization (ORa = 0.58, 95% CI = 0.35-0.97). The findings of this study demonstrate that IPV experiences are negatively associated with willingness to use PrEP among MSM, suggesting that PrEP promotion programs should consider IPV screening and develop explicit intervention strategies for both perpetrators and victims.

Abstract
Poor medication adherence is a pervasive issue with considerable health and socioeconomic consequences. Although the underlying reasons are generally understood, traditional intervention strategies rooted in patient-centric education and empowerment have proved to be prohibitively complex and/or ineffective. Formulating a pharmaceutical in a drug delivery system (DDS) is a promising alternative that can directly mitigate many common impediments to adherence, including frequent dosing, adverse effects and a delayed onset of action. Existing DDSs have already positively influenced patient acceptability and improved rates of adherence across various disease and intervention types. The next generation of systems have the potential to instate an even more radical paradigm shift by, for example, permitting oral delivery of biomacromolecules, allowing for autonomous dose regulation and enabling several doses to be mimicked with a single administration. Their success, however, is contingent on their ability to address the problems that have made DDSs unsuccessful in the past.

Abstract
The HIV epidemic affects men who have sex with men (MSM) disproportionally in Brazil, and pre-exposure prophylaxis (PrEP) is effective for preventing HIV in this population. However, low perceived risk of HIV may influence the acceptability and decision to use PrEP. This study estimated the association between self-perception of HIV risk and acceptability of daily oral PrEP among Brazilian MSM. Respondent-driven sampling (RDS) was used for behavioral and biological surveillance to recruit 4,176 MSM 18 years or over in 12 Brazilian cities in 2016. Results were weighted using Gile's estimator in RDS Analyst software. Adjusted odds rations (OR) with 95% confidence intervals were calculated using multivariate logistic regression. Acceptability of daily oral PrEP was high (69.7%) among the 3,544 MSM available for analysis. Most participants self-reported low or moderate risk of HIV infection (67.2%) and a small proportion (9.3%) reported high risk. A dose-response relationship was observed between acceptability of PrEP and self-reported risk: PrEP acceptability was 1.88 times higher (OR 1.8; 95% CI: 1.24-2.85) among MSM whose perceived risk of HIV infection was low or moderate, and 5 times higher (OR 5.68; 95% CI: 2.54-12.73) among those who self-reported high risk compared to MSM reporting no HIV risk. MSM with the highest risk perception of HIV reported higher rates of PrEP acceptability. Given the availability of daily oral PrEP in the public health care system in Brazil, we suggest emphasizing counseling about self-perception of HIV risk as part of routine HIV prevention services.

Abstract
Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was recently approved for HIV prevention as an alternative to daily oral PrEP. We explored preferences and attitudes toward LAI-PrEP among Black, Hispanic/Latino, and White gay, bisexual, and other men who have sex with men (GBM) using focus groups (n = 13) and in-depth interviews (n = 17). Participants expressed differing levels of interest in LAI-PrEP. While important benefits of LAI-PrEP included convenience, provider-facilitated PrEP discussion, and expansion of PrEP options, participants raised concerns about treatment efficacy and side effects, discomfort with needles/injections, cost, and frequency of clinic visits. Our findings highlight ongoing challenges with accessing HIV-prevention tools and provide guidance for developing strategies to enhance LAI-PrEP uptake among GBM.

Abstract
Background Outbreaks of new HIV transmission among people who inject drugs (PWID) are a major public health concern. Oral daily PrEP, has been identified as a critical addition to the biomedical toolkit for this population. However, limited research on the acceptability of long-acting injectable PrEP has been conducted with this population. Methods We conducted a cross sectional multi-site survey with 1127 participants from May 2019–February 2020 to assess the acceptability of novel PrEP regimens. We computed bivariate and multivariable logistic regressions to evaluate correlates of the outcome variable: acceptability of 3-month injectable-PrEP. SAS v.9.4 was used to conduct statistical analysis. Results Limited knowledge of or use of PrEP, past or present, was evident within the sample. Injection drug use in the past six months was significantly associated with LA injectable PrEP acceptability, with the odds of acceptability being 1.885 (CI: 1.376, 2.582) times greater than those who did not inject drugs. After adjusting for confounders, injection drug use was significantly associated with the outcome, such that the odds of acceptability of LA injectable PrEP were 1.705 (CI: 1.198, 2.427) times greater among PWID compared to those who did not inject drugs (p < 0.03). The results demonstrate acceptability (38.2%) in a durable (3-month) injectable PrEP modality among participants who also identified as PWID. Conclusions PrEP promotion efforts among PWID to increase access to long-acting injectable PrEP are necessary. Through efforts to increase acceptance and regular use of long-acting injectable PrEP, public health strategies may be able to effectively lessen chances of future HIV outbreaks among PWID.

Although new methods of pre-exposure prophylaxis (PrEP), such as long-acting injectable (LAI-PrEP), have been approved by the Food and Drug Administration, their acceptability among aMSM/aTGW is not well known. Methods Forty-eight semi-structured interviews were conducted to assess the knowledge and interest in LAI-PrEP among aMSM/aTGW enrolled in a daily oral PrEP cohort from two capital cities of Brazil since 2019. Results Previous knowledge of LAI-PrEP remains scarce, but the high interest regarding its use has been reported. Interest in the use of LAI-PrEP is associated with eliminating the burden of daily responsibility or the risk of missing the necessary medications, lowering the costs of this method, increasing confidentiality, and decreasing the frequency of visiting PrEP clinics. The reported barriers to uptake included fear of injection, doubts on its effectiveness, side effects, and greater dependence on a health provider. Conclusions There is an urgent need to strengthen the preventive strategies against HIV infection among the youth, enhance their knowledge and those of healthcare providers, and offer safe and new options.

Abstract
The HIV epidemic disproportionately impacts men who have sex with men (MSM), particularly those who use stimulants. We explored barriers and facilitators to pre-exposure prophylaxis (PrEP) uptake among this population. From June 2018 through February 2019, we conducted semi-structured interviews in Providence, Rhode Island, and New Haven, Connecticut, with 21 MSM who reported recent (past six months) stimulant use. We identified individual, interpersonal, and structural barriers to PrEP, including: (1) high awareness but mixed knowledge of PrEP, resulting in concerns about side effects and drug interactions; (2) interest that was partly determined by substance use and perceived HIV risk; (3) fragmented and constrained social networks not conducive to disseminating PrEP information; and (4) PrEP access, such as insurance coverage and cost. Our findings suggest potential approaches to increase PrEP uptake in this group, including promotion through mainstream and social media, clarifying misinformation, and facilitating increased access through structural interventions.

Intimate Partner Violence and Preferences for Pre-exposure Prophylaxis (PrEP) Modes of Delivery Among A Sample of Gay, Bisexual, and Other Men Who Have Sex with Men. AIDS Behav 2022; 26:2425-2434.

Abstract
While there is strong evidence that the experience of intimate partner violence (IPV) shapes PrEP use among heterosexual women, evidence for similar relationships among gay, bisexual and other men who have sex with men (GBMSM) is scant. In this paper we analyze baseline data from a large randomized controlled trial (RCT) of an HIV prevention intervention for GBMSM recruited from three cities (Atlanta, Detroit and New York City) to examine how the recent experience of IPV shapes their rankings of PrEP delivery options. Men were asked to rank from 1 to 8 PrEP taken by daily pill, event-based pill, injection, anal suppository (before sex), suppository (after sex), gel (penile or rectal) (before sex), and gel (after sex) and condoms. The analysis sample is 694 HIV-negative, sexually active GBMSM. Analysis considers an ordinal outcome measuring participant's ranked preferences for their future use of eight HIV prevention options. Men who experienced physical IPV preferred PrEP in pill form, while men who experienced partners monitoring their behaviors (monitoring IPV) preferred PrEP by injection. Men who experienced emotional IPV ranked PrEP by pill lower than other methods. Sexual and controlling IPV were not significantly associated with PrEP modality ranking. As more modes of PrEP delivery become available, providers should be encouraged to screen GBMSM seeking PrEP for IPV, and to provide men with the necessary information to facilitate an informed choice when deciding on a PrEP modality that will work for them and their relationship context.

[PMID: 35756401 PMCID: PMC9225882 DOI: 10.1155/2022/1862396] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/10/2022] [Accepted: 05/16/2022] [Indexed: 12/28/2022]
Abstract
Background In recent years, influenced by the continuous improvement and development of the medical service model and the increasing demands of modern people for the quality of clinical care, the clinical treatment of schizophrenic groups has also received widespread attention and importance from all sectors of society. Psychobehavioral care is administered to patients during active antipsychotic treatment, which can maximize the patient's cooperation with clinical work and thus play an auxiliary role in treatment. Aims To investigate the impact of emotional-behavioral responses, cognitive changes in outpatient follow-up of schizophrenic patients with integrated psychobehavioral care. Materials and Methods One hundred cases of schizophrenia patients with outpatient follow-up in our hospital from March 2017 to March 2019 were selected as prospective study subjects and divided into a comparison group and an observation group of 50 cases each according to a random number table. Among them, the comparison group implemented conventional psychobehavioral care, and the observation group implemented integrated psychobehavioral care. The differences in compliance behavior, negative emotions, cognitive behavioral changes, and pain scores before and after care of schizophrenia patients in the outpatient follow-up were compared between the two groups. Results After care, the compliance behavior, negative emotions, cognitive behavioral changes, and pain scores of schizophrenia patients in both groups with outpatient follow-up were significantly improved and significantly higher in the observation group than in the comparison group, and statistics showed that this difference was statistically significant (P < 0.05). Conclusion Integrated psychobehavioral care combined with conventional psychobehavioral care can effectively enhance the compliance behavior of outpatient follow-up schizophrenia patients, improve the negative emotions and pain of patients, and facilitate the active treatment of patients to improve their prognosis. It has some reference value for outpatient follow-up schizophrenia patient care.

Abstract
Long-acting injectable (LAI) modalities have been developed for ART and PrEP. Women face unique barriers to LAI use yet little research has examined women's perceptions of potential LAI HIV therapy candidates. We conducted 89 in-depth interviews at six Women's Interagency HIV Study (WIHS) sites with women living with HIV (n = 59) and HIV-negative women (n = 30) from 2017 to 2018. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Participants identified specific sub-populations who could most benefit from LAI over daily pills: (1) young people; (2) women with childcare responsibilities; (3) people with adherence-related psychological distress; (4) individuals with multiple sex partners; and (5) people facing structural insecurities such as homelessness. Women are underserved by current HIV care options and their perspectives are imperative to ensure a successful scale-up of LAI PrEP and LAI ART that prioritizes equitable access and benefit for all individuals.

Safety and Pharmacokinetic Profiles of Long-Acting Injectable Antiretroviral Drugs for HIV-1 Pre-Exposure Prophylaxis: A Systematic Review and Meta-analysis of Randomized Trials. Front Pharmacol 2021; 12:664875.

Abstract
Objectives: To investigate the safety and pharmacokinetic profiles of long-acting injectable pre-exposure prophylaxis (LAI PrEP), notably cabotegravir (CAB-LA) and rilpivirine (RPV-LA), for the prevention of human immunodeficiency virus-1 (HIV-1) infection. Methods: Eligible randomized trials of LAI PrEP in HIV-uninfected and/or healthy patients were included and assessed with the Revised Cochrane risk-of-bias tool for randomized trials. Where feasible, a meta-analysis was performed for safety outcomes by using a random-effects model with risk ratios and their 95% confidence intervals as the common effect measure. The protocol was registered with PROSPERO CRD42020154772. Results: Eight studies cumulating a total of 666 participants were included in this systematic review, including five (362 intervention-arm volunteers) and four trials (194 intervention-arm volunteers) that investigated CAB-LA and RPV-LA, respectively. We found that both CAB-LA and RPV-LA were generally well-tolerated as their safety profiles were similar to placebo in terms of any adverse event (AE), serious AE, and AE-related withdrawals. Furthermore, pharmacokinetic analyses revealed favorable prospects in viral inhibitory activity of CAB-LA and RPV-LA. Intramuscular (IM) injection of CAB-LA 600 mg Q8W was superior to CAB-LA 800 mg Q12W in male participants, while the same was true for RPV-LA 1200 mg IM Q8W over other dosing regimens. Although these results are promising, further research is required to confirm the findings on RPV-LA as current evidence is limited. Conclusion: CAB-LA and RPV-LA have promising safety and pharmacokinetic profiles. The preventive efficacy of these agents is being evaluated in Phase 3 trials.

Abstract
Background HIV Pre-exposure prophylaxis (PrEP) is being considered for implementation among MSM nationwide in Vietnam. However, there may be concerns about potential obstacles for PrEP adherence among Vietnamese MSM. This study aims to assess the acceptability to use PrEP, potential barriers and facilitators, and the preferences for PrEP service accessibility and delivery among Vietnamese MSM. Methods Four focus group discussions (FGDs) were conducted with 30 HIV-negative MSM in January 2018 in Hanoi, Vietnam. FGDs explored MSM’s awareness regarding PrEP, perceived benefits and barriers of PrEP use, and willingness to use PrEP. FGDs were audio-recorded and transcribed verbatim. Content analysis was used. Results The mean age of participants was 23.9 years old. Most participants realized the advantages of PrEP given its efficacy in HIV risk reduction and expressed high motivation and interest to use PrEP in the future. PrEP was considered as a supplement alongside condoms. Common concerns about PrEP included side-effects, forgetting to take the pill daily, stigmatization due to using PrEP, negative attitudes toward PrEP from other MSM and accessibility of PrEP. Participants would prefer an injectable PrEP regime if available as it was seen as easier to adhere to. Concerns were also raised that PrEP usage could be interpreted as an indication of engaging in sexual risk behavior for HIV, potentially causing suspicion in love relationships or by family and friends. Participants preferred to receive PrEP in civil business organizations and MSM-friendly clinics, and recommended that pharmacy stores would not be suitable for PrEP implementation due to lack of trust and fear of fake drugs. Conclusion This study indicated a high level of willingness to use PrEP among MSM in Vietnam in combination with condom. Strategies to raise awareness of PrEP, reduce stigma towards PrEP, and improve the accessibility among MSM in Vietnam is needed. Existing MSM-friendly clinics were recommended to implement PrEP programs in Vietnam.

Abstract
HIV-1/AIDS remains a global public health problem. The world health organization (WHO) reported at the end of 2019 that 38 million people were living with HIV-1 worldwide, of which only 67% were accessing antiretroviral therapy (ART). Despite great success in the clinical management of HIV-1 infection, ART does not eliminate the virus from the host genome. Instead, HIV-1 remains latent as a viral reservoir in any tissue containing resting memory CD4+ T cells. The elimination of these residual proviruses that can reseed full-blown infection upon treatment interruption remains the major barrier towards curing HIV-1. Novel approaches have recently been developed to excise or disrupt the virus from the host cells (e.g., gene editing with the CRISPR-Cas system) to permanently shut off transcription of the virus (block-and-lock and RNA interference strategies), or to reactivate the virus from cell reservoirs so that it can be eliminated by the immune system or cytopathic effects (shock-and-kill strategy). Here, we will review each of these approaches, with the major focus placed on the block-and-lock strategy.

Abstract
Long-acting and extended-release formulations represent one of the most important approaches to improving the treatment and prevention of chronic HIV infection. Long-acting small molecules and monoclonal antibodies have demonstrated potent anti-HIV activity in early- and late-stage clinical trials. Strategies to manage toxicity and falling drug concentrations after missed doses, as well as primary and secondary resistance to current drugs and monoclonal antibodies are important considerations. Long-acting injectable nanoformulations of the integrase inhibitor cabotegravir and the non-nucleoside reverse transcriptase inhibitor rilpivirine were safe, well tolerated and efficacious in large randomised phase 3 studies. Regulatory approval for this two-drug combination for HIV maintenance therapy was granted in Canada in 2020 and is expected in the USA during 2021. 4'-Ethynyl-2-fluoro-2'-deoxyadenosine (islatravir) is a novel nucleoside reverse transcriptase inhibitor in clinical development as a long-acting oral drug and as a long-acting subcutaneous polymer implant. GS-6207 is a novel HIV capsid inhibitor that is injected subcutaneously every 3 months. Broadly-neutralising monoclonal antibodies have potent antiviral activity in early human trials, however there is substantial baseline resistance and rapid development of resistance to these antibodies if used as monotherapy. Limitations of these antiretroviral approaches include management of toxicities and prevention of drug resistance when these drugs are discontinued and drug concentrations are slowly reduced over time. These approaches appear to be especially attractive for patients complaining of pill fatigue and for those experiencing HIV-associated stigma. As these formulations are shown to be safe, well tolerated and economical, they are likely to gain broader appeal.

Abstract
Intimate partner violence (IPV) significantly increases HIV risk among MSM. Pre-exposure prophylaxis (PrEP) may provide MSM experiencing IPV an option for self-protection from HIV without requiring condom negotiation or compromising safety. This study examined relationships among various forms of IPV (physical, emotional, monitoring, controlling, and forced sex) and PrEP use among 863 MSM participating in a cross-sectional, internet-based survey. Participants reported IPV rates during the prior 6 months that were consistent with prior research (physical violence, 23.3%; emotional violence, 36.3%; monitoring, 45.1%; controlling, 25.3%; forced sex, 20.0%). Forced sex and emotional IPV were negatively associated with PrEP use in our sample; in contrast, controlling was positively associated with PrEP use. We suggest clinical IPV screenings among MSM seeking PrEP, as well as PrEP-focused interventions that explicitly address IPV.

Abstract
The study evaluates the acceptability and preferences for long-acting antiretroviral therapy (LA-ART) among a diverse cohort of people with HIV infection (PWH). It consists of a self-administered survey and chart review of PWH presenting to an HIV clinic in Houston, Texas, between February and June 2018; 374 participants were included; 61% indicated that they were likely or very likely to use LA-ART formulations. When asked about preference, 41% preferred pills, 40% preferred injections, and 18% preferred an implant. The most common benefit reported was eliminating the need to remember taking daily HIV pills (74%); 43% were worried that LA-ART will not be as effective as pills. Participants with a college degree, men who have sex with men, and ART-experienced were more willing to use LA-ART. Participants who reported poor or fair health, or who screened positive for depression or anxiety were significantly less willing to use LA-ART. The likelihood of using LA-ART did not correlate with self-reported adherence and HIV suppression. Patients with difficulty scheduling and attending clinic visits preferred injections and implant over pills. Most participants indicated a willingness to use new LA ART formulations. However, 41% still prefers pills, and those more interested in LA-ART were not less adherent.

Abstract
Recent clinical trial data showed that injectable long-acting antiretroviral treatment (LA-ART) every four or eight weeks could become an alternative option for HIV treatment or prevention. The purpose of our study was to explore perceptions and potential users' points of views of this new mode of administration through individuals' therapeutic itinerary and their singular history with ART. Between 2018 and 2019, a qualitative study was conducted in two University Hospitals in Paris, France. In-depth interviews were conducted with 15 virologically controlled People Living with HIV (PLWH) and 13 men on pre-exposure prophylaxis (PrEP) for at least six months. Interviews, focused on the daily experience with ART, were recorded, transcribed, and analyzed using thematic content analysis. Collected discourses were organized around three emergent concerns: social, material and experimental. Each of these concerns was perceived as ambivalent, balanced by skepticism and hope. It revealed the complexity of each individual's relationship to their HIV treatment or PrEP, leading to balance the injectable LA-ART popularity reported within clinical trials. This new mode of administration may be a suitable alternative for some PLWH and PrEP users, a "simplification" compared to the oral route. It opens a window for "customizable" ART-treatment according to individuals' lives.

Abstract
Increasing prescription of pre-exposure prophylaxis (PrEP) is imperative to ending the HIV epidemic in the United States. The objective of this review was to identify health care provider barriers to PrEP implementation. A systematic review was conducted in February 2019 using PubMed to identify barriers to PrEP prescribing practices in the United States. Targeted search terms surrounding PrEP and providers resulted in 222 original studies, 28 of which were ultimately included in our review, with data collected between 2011 and 2018. Six themes were identified across reviewed studies: (i) a lack of PrEP knowledge, (ii) the presence of the Purview Paradox, which refers to discordance in beliefs between HIV specialists and primary care providers on who should prescribe PrEP, (iii) concerns about PrEP costs, (iv) concerns about behavioral and health consequences, (v) interpersonal stigma, and (vi) concerns about patient adherence. A majority of providers were lacking knowledge regarding PrEP, resulting in discomfort in prescribing PrEP, or limited awareness and understanding of PrEP clinical guidelines. Discrepant opinions were identified regarding whether PrEP was best managed within primary care or specialty clinics. Other barriers included concerns about cost, patient adherence, and follow-up maintenance care. Finally, concerns about risk compensation and discomfort discussing sexual activities with patients who would benefit most from PrEP were apparent. Additional work is needed to prepare providers to prescribe and manage patients on PrEP, optimize PrEP delivery, and reduce provider bias. Future research is needed to identify providers' attitudes and beliefs regarding innovations in PrEP dosing, task shifting, and novel strategies for PrEP care.

Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) is not widely available in China. Previous studies reported low awareness and inconclusive findings on the acceptability of PrEP among Chinese men who have sex with men (MSM). METHODS We conducted a secondary analysis of an online national survey comparing preferences for oral and long-acting injectable PrEP among MSM and identifying correlates of preferences. The study did not collect detailed information about partner types that may influence negotiated safety and PrEP uptake. RESULTS Nine-hundred and seventy-nine men from the larger sample of 1045 men responded to the PrEP survey questions. Most men (81.9%) had never heard of PrEP, but reported interest in using PrEP. More participants chose injectable PrEP (36.3%) as their preferred formulation than oral PrEP (24.6%). Men who had at least two HIV tests (adjusted OR = 1.36, 95%CI 1.04, 1.78) more commonly preferred injectable PrEP. CONCLUSION Our findings may help inform PrEP messaging in areas where PrEP has yet to be scaled up.

Abstract
OBJECTIVES This study's primary objective was to characterize attitudes to long-acting antiretrovirals (LAARV), among youth aged 13-24 years living with perinatally acquired HIV and nonperinatally acquired HIV. Secondary objectives included: assessing whether those with detectable HIV RNA PCR viral load had higher enthusiasm for LAARV compared to those with suppressed viral load, and examining characteristics associated with LAARV enthusiasm. METHODS A cross-sectional survey of 303 youth living with HIV (YHIV) followed at 4 pediatric/adolescent HIV clinics in the United States was performed to determine interest in LAARV, using a modified survey instrument previously used in adults. Interest in LAARV across groups was compared. Poisson regression with robust variance was used to determine the impact of various characteristics on interest in LAARV. FINDINGS Overall, 88% of YHIV reported probable or definite willingness to use LAARV. The enthusiasm level was similar between youth with perinatally acquired HIV and nonperinatally acquired HIV (P = 0.93). Youth with HIV viral load >1000 copies per milliliter had significantly higher interest than youth with suppressed viral load [prevalence ratio 1.12 (95% confidence interval: 1.03 to 1.20); P = 0.005]. Female youth participants who had had past experience with implantable contraceptive methods had a significantly higher interest in LAARV (100% vs. 85.5%; P = 0.002). Proportion of respondents endorsing definite willingness to use was significantly higher with decreased injection frequency compared with increased injection frequency. INTERPRETATION YHIV at 4 urban US pediatric/adolescent HIV clinics had high levels of enthusiasm for LAARV. LAARV should be given high priority as a potentially viable treatment option to improve clinical outcomes in YHIV.

Abstract
Brazil has recently integrated HIV Pre-exposure Prophylaxis (PrEP) into its public health system and offered to key populations such as transgender women (TGW). This study investigates factors associated with PrEP refusal among TGW living in one of the largest and poorest cities of Brazil. We recruited 127 TGW using Respondent Driven Sampling (RDS) in Salvador, Brazil. Latent class analysis (LCA) was used to define acceptability of PrEP. Two latent classes were identified: "high acceptability of PrEP" (91.3%) and "PrEP refusal" (8.7%). PrEP was less acceptable among white TGW and among those age 25 or older, with income above minimum wage (≥ US$252.87), and reporting unprotected receptive anal intercourse with (URAI) causal partners. The findings highlight how nuanced strategies that takes into consideration unique characteristics are needed to effectively address the acceptability of PrEP.

Abstract
Efforts in San Francisco are maximizing the use of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) where high levels of use are needed to maximize reducing new HIV infections. National HIV Behavioral Surveillance surveys MSM in San Francisco. Demographics, health care and risk behaviors are assessed. PrEP use is measured for 12 month, 6 month and 30 day periods. Of 399 HIV uninfected men sampled in 2017, 43.4% used PrEP in the past 12 months. Proportions of men using PrEP by race/ethnicity were not significant at any time point. Decreases between 6 month and 30 day use were highest among African American and Latino men. These men had the highest proportion of intermittent use in the past 30 days but not significantly. While our data suggest the disparity in PrEP use by race/ethnicity has narrowed in San Francisco, novel delivery of PrEP may narrow disparity further.

Abstract
INTRODUCTION Existing HIV therapy using oral antiretrovirals (ARVs) can result in pill fatigue and sub-optimal adherence. Microneedle array patches (MAPs) offer non-invasive, blood-free and painless drug delivery, and may improve patient adherence. The objective of this study was to develop a novel physiologically-based pharmacokinetic (PBPK) model to simulate the systemic pharmacokinetics of cabotegravir and rilpivirine MAPs using the intradermal route. METHODS The developed PBPK models were qualified against observed pharmacokinetic data after intramuscular (IM) and intradermal administration of long-acting nanoformulated rilpivirine to rats, and for IM administration of both drugs to healthy adults. Qualified models were then utilised to estimate suitable MAP characteristics (e.g. nanoformulation dose and release rates) and inform dosing strategies to maintain plasma concentrations above target trough concentrations for the designated dosing interval. RESULTS PBPK models simulated q4-weekly loading and maintenance doses of 360 mg and 180 mg for long-acting formulated cabotegravir between the release rates of 1 × 10-3-3 × 10-3h-1 and 1 × 10-3-1.5 × 10-3h-1 respectively, for a 70 kg adult. Estimated patch size was 60 cm2 for a 360 mg dose of cabotegravir. For q4-weekly dosing, rilpivirine required a 1080 mg loading dose and a 540 mg maintenance dose with release rates of 1.5 × 10-3-2.5 × 10-3h-1 and 5 × 10-4-1 × 10-3h-1, respectively. Weekly dosing was also evaluated to assess the potential application from a smaller patch size. The ability to self-administer via a patch that is only left in place for a short duration makes longer durations less important than for some other long-acting approaches. Weekly cabotegravir required 60 mg between release rates 7 × 10-3-9 × 10-3h-1 and rilpivirine required 270 mg and 180 mg respectively between release rates of 7 × 10-3-9 × 10-3h-1. DISCUSSION This model estimated optimal dose and release rates for cabotegravir and rilpivirine MAPs. Our approach provides a computational platform to support rational development of intradermal administration strategies to tackle problems associated with chronic oral ARV administration.

Abstract
Background Heterosexual men in South Africa are a large key population to exposure to HIV, yet preferences for HIV pre-exposure prophylaxis (PrEP) among this population have not, to date, been investigated in the literature. This paper aims to explore HIV prevention preferences among heterosexual men in urban South Africa, as well as to examine the demand and characteristics of men who favour long-acting injectable (LAI) PrEP over condoms and oral PrEP. Methods Data were collected among 178 self-reported HIV-negative heterosexual men, who were given example products and information before being asked which they preferred. Multivariate logistic regression was used to analyse which characteristics were associated with product choice. Results 48% (n = 85) of participants preferred LAI PrEP, while 33% (n = 58) and 20% (n = 35) chose oral PrEP and condoms respectively. Having children (marginal effect = 0.22; 95% CI [0.01, 0.44]) or having higher risk attitude scores (marginal effect = 0.03; 95% CI [0.01, 0.06]) was significantly associated with a choice of LAI PrEP, while those who had unprotected anal intercourse (marginal effect = − 0.42; 95% CI [− 0.57, − 0.27]) and those who were concerned with protection against other sexually transmitted infections over HIV (marginal effect = − 0.42; 95% CI [− 0.60, − 0.24]) appeared less likely to prefer LAI PrEP. Conclusions The results suggested a relatively high demand and theoretical acceptability for LAI PrEP among heterosexual men in urban South Africa, but there appeared to be fewer distinct predictors for the willingness to use LAI PrEP compared to studies conducted among gay and bisexual men and women. Nevertheless, the findings contribute to the mapping of the demand and determinants of heterosexual men’s preferences for novel antiretroviral-based prevention in sub-Saharan Africa, and the data could aid in the differentiated design of future HIV prevention strategies using LAI PrEP in conjunction with other methods.

Abstract
Brazil has the largest population of individuals living with HIV/AIDS in Latin America with a disproportional prevalence of infection among men who have sex with men (MSM). This study evaluated PrEP awareness by age (18-24, 25-35, ≥36 years), its associated factors and the willingness to use HIV prevention technologies among MSM using a GSN app in Brazil. Inclusion criteria were ≥18 years-old, cisgender men and HIV-negative serostatus. Of 7242 individuals, 4136 (57%) completed the questionnaire. PrEP awareness was reported by 51% (though lower among MSM aged 18-24 and ≥36 years) and its associated factors were higher family income, most friends with the same sexual orientation, high number of male sexual partners and marijuana use. HIV testing (never vs. at least once) lead to an almost 3-fold increase in the odds of PrEP awareness. High HIV risk perception led to increased PrEP awareness only among MSM aged 18-24 years. A total of 2335 (56%) was willing to use daily oral PrEP. PrEP awareness remains low in Brazil and mobile tools are key strategies to reach MSM and increase awareness of prevention technologies. Community-based interventions could add to online campaigns to reach the most vulnerable, which include young, non-white and lower-income MSM.

Abstract
Researchers have established that substance use interferes with anti-retroviral medication adherence among gay and bisexual men (GBM) living with HIV. There is limited parallel examination of pre-exposure prophylaxis (PrEP) adherence among HIV-negative GBM. We conducted retrospective 30-day timeline follow-back interviews and prospective semi-weekly diary data for 10 weeks with 104 PrEP-using GBM, half of whom engaged in club drug use (ketamine, ecstasy, GHB, cocaine, or methamphetamine)-generating 9532 days of data. Participants reported their day-by-day PrEP, club drug, marijuana, and heavy alcohol use (5 + drinks in one sitting). On average, club drug users were no more likely to miss a dose of PrEP than non-club drug users (M = 1.6 doses, SD = 3.0, past 30 days). However, we found that club drug use (at the event level) increased the odds of missing a dose on the same day by 55% and the next day (e.g., a "carryover effect") by 60%. Further, missing a dose on one day increased the odds of missing a dose the following day by eightfold. We did not identify an event-level effect of marijuana use or heavy drinking on PrEP adherence. Our data suggest club drug users could have greater protective effects from daily oral or long-acting injectable PrEP compared to a time-driven PrEP regimen because of the concurrence of club drug use and PrEP non-adherence.

PLoS One 2018; 13:e0209484. [PMID: 30592756 PMCID: PMC6310267 DOI: 10.1371/journal.pone.0209484] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Accepted: 12/06/2018] [Indexed: 11/18/2022] Open
Abstract
Pre-exposure prophylaxis (PrEP) is effective in preventing HIV infections among men who have sex with men (MSM). PrEP uptake and adherence remain low and product preferences are unknown, especially among young African American MSM who are most at-risk. We conducted 26 qualitative interviews from 2014-2016 among young adult HIV-negative African American MSM regarding PrEP product preferences in Missouri. While the pill and injectable were most liked of all modalities, about a quarter preferred rectal products or patches. Most participants preferred a long-acting injectable (LAI) to daily oral pills due to better medication adherence and a dislike for taking pills. Many participants preferred daily oral pills to on-demand oral PrEP due to the inability to predict sex and the perception that insufficient time or medication would not achieve HIV protection with on-demand. A fear of needles and the perception that there would not be therapeutic levels for a long duration were concerns with injectable PrEP. Study findings highlight the need for a range of prevention options for African American MSM and can inform PrEP product development as well as dissemination and implementation efforts.

Abstract
INTRODUCTION Despite documented effectiveness of pre-exposure prophylaxis (PrEP), PrEP uptake remains low among men who have sex with men (MSM), the population bearing the highest HIV burden in the U.S. OBJECTIVES To elicit MSM stakeholder preferences in order to inform program development aimed at improving uptake of PrEP. METHODS 554 MSM were recruited through social networking applications to complete a stated preference [choice-based conjoint (CBC)] survey. Respondents completed 14 choice tasks presenting experimentally varied combinations of five attributes related to PrEP administration (dosing frequency, dispensing venue, prescription practices, adherence support, and costs). Latent class analysis was used to estimate the relative importance of each attribute and preferences across seven possible PrEP delivery programs. RESULTS Preferences clustered into five groups. PrEP affordability was the most influential attribute across groups, followed by dosing strategy. Only one group liked daily and on-demand PrEP equally (n = 74) while the other four groups disliked the on-demand intermittent option. Monthly injectable PrEP is preferred by two (n = 210) out of the five groups, including young MSM. Two groups (n = 267) were willing to take PrEP across all the hypothetical programs. One group (n = 183) almost exclusively considered costs in their decision-making. Participants in the most racially diverse among groups (n = 88) had a very low level of interest in PrEP initiation. CONCLUSION Our data suggest that PrEP uptake will be maximized by making daily PrEP affordable to MSM and streamlining PrEP consultation visits for young MSM. Young MSM should be prioritized for injectable PrEP when it becomes available. A successful PrEP program will spend resources on removing structural barriers to PrEP access and educating MSM of color, and will emphasize protection of privacy to maximize uptake among rural/suburban MSM.

Abstract
Adherence challenges with oral pre-exposure prophylaxis have stimulated interest in alternate modes of administration including long-acting injections. We conducted 30 in-depth interviews with 26 male trial participants and 4 clinical providers in a Phase IIa study (ÉCLAIR) evaluating the use of long-acting cabotegravir (CAB-LA) injections in New York and San Francisco. Interviews exploring attitudes and experiences with CAB-LA were audiotaped, transcribed, and analyzed using thematic content analysis. Despite a high frequency of some level of side effects, almost all participants reported being interested in continuing with CAB-LA, versus a daily oral, due to its convenience and the perceived advantage of not worrying about adhering to pills. Providers reinforced the importance of CAB-LA as a prevention option and the need for guidelines to assist patient decision-making. Further research is needed on the acceptability of CAB-LA among men and women at higher risk for HIV in different settings.

Abstract
Literature concerning pre-exposure prophylaxis (PrEP) among gay and bisexual identifying men (GBM) has explored facilitators and barriers to uptake and adherence. Far less reported are the reasons why GBM discontinue PrEP use. A national sample of 1071 GBM completed surveys about PrEP use and discontinuation. Participants who were still taking PrEP the 24-month follow up were compared to those that had stopped. Eighteen percent (n = 31) of GBM who reported ever using PrEP discontinued use. Younger (AOR = 0.96; 95% CI 0.92-1.00), and unemployed (AOR = 4.58; 95% CI 1.43-14.70) GBM were more likely to discontinue PrEP than their counterparts. Those that discontinued provided details on why via a free response question. The most common reasons for discontinuation were lower perceived HIV risk (50%) and cost/insurance (30%). Reasons for potential re-initiation included higher-risk sexual activities and changes to structural related barriers. More research is needed to inform interventions on how GBM can continue taking PrEP during changes to employment that effect insurance coverage and cost.

Poppers and PrEP: Use of Pre-exposure Prophylaxis Among Men Who Have Sex with Men Who Use Inhaled Nitrites. AIDS Behav 2018; 22:3658-3672.

Abstract
Men who have sex with men (MSM) commonly use inhaled nitrites, or poppers, though their use is a risk factor HIV seroconversion. Pre-exposure prophylaxis, or PrEP, is effective for HIV prevention, but is not widely used, and little is known regarding PrEP use and acceptability among MSM who use inhaled nitrites. We surveyed 580 MSM in Paris, France in 2016 about popper use, sexual behaviors including condomless anal intercourse (CAI), serosorting, and sexual positioning, PrEP use, PrEP candidacy, and interest in alternate PrEP delivery modalities. We included 444 HIV negative participants for the current study. 46.2% reported popper use in the prior 3 months. Using multivariate adjusted logistic regression, we found that popper users were more likely than non-users to consider themselves candidates for PrEP [adjusted relative risk ratio (aRRR) = 2.73; 95% CI 1.54-4.83], but they were not more likely to be current (aRRR = 1.54; 95% CI 0.71-3.33) or past (aRRR = 1.37; 95% CI 0.44-4.28) PrEP users. Mediation analyses indicated that increased CAI and serosorting partly explained the relationship between popper use and PrEP candidacy. There was considerable interest in alternate proposed PrEP delivery modalities, particularly long-acting injectable PrEP [adjusted risk ratio (aRR) = 1.43; 95% CI 1.15-1.79].

Abstract
Non-adherence to medication is an important health care problem, especially in the treatment of chronic conditions. Injectable long-acting (LA) formulations of antiretrovirals (ARVs) represent a viable alternative to improve adherence to HIV/AIDS treatment and prevention. However, the LA-ARV formulations currently in clinical trials cannot be removed after administration even if adverse events occur. Here we show an ultra-LA removable system that delivers drug for up to 9 months and can be safely removed to stop drug delivery. We use two pre-clinical models for HIV transmission and treatment, non-human primates (NHP) and humanized BLT (bone marrow/liver/thymus) mice and show a single dose of subcutaneously administered ultra-LA dolutegravir effectively delivers the drug in both models and show suppression of viremia and protection from multiple high-dose vaginal HIV challenges in BLT mice. This approach represents a potentially effective strategy for the ultra-LA drug delivery with multiple possible therapeutic applications. Long-acting (LA) formulations of antiretroviral (ARV) drugs are an alternative approach to improve adherence for HIV treatment and prevention. Here the authors show a removable biodegradable ultra-LA-ARV drug system that effectively delivers drug, controls viremia and prevents infection in animal models of HIV infection.

Abstract
Young men who have sex with men account for approximately 20% of incident HIV infections in the U.S. Antiretroviral pre-exposure prophylaxis (PrEP) administered as a daily pill has been shown to decrease HIV acquisition in at-risk individuals. New modalities for PrEP are being developed and tested, including injectable PrEP; however, acceptability of these emerging modalities has not yet been examined in youth. We conducted six focus groups with 36 young men and transgender men and women who have sex with men in Boston, Chicago, and Los Angeles in 2016 to assess interest in and preference for different PrEP modalities. Youth were purposively recruited based on diversity of age, race/ethnicity, and prior PrEP experience. Data were coded using content coding based on key domains of the interview guide, in particular around the central themes of interest in and barriers and facilitators to injectable PrEP use. Participants were knowledgeable about oral PrEP but suggested barriers to broader uptake, including stigma, marginalization, and access to information. While participants were split on preference for injectable versus oral PrEP, they agreed quarterly injections may be more manageable and better for those who have adherence difficulties and for those who engage in sex more frequently. Concerns specific to injectable PrEP included: severity/duration of side effects, pain, level of protection prior to next injection, distrust of medical system and injections, and cost. Understanding barriers to and preferences for diverse prevention modalities will allow for more HIV prevention options, improved products, and better interventions, thus allowing individuals to make informed HIV prevention choices.

Abstract
PURPOSE Pre-exposure prophylaxis (PrEP) is an effective strategy to prevent HIV. However, low uptake of daily oral PrEP since Food and Drug Administration approval and low medication adherence among users have stimulated the investigation of other modalities for delivery, such as injectable PrEP and on-demand PrEP. The objective of this study was to determine the demographic and behavioral predictors of willingness to try alternative PrEP delivery mechanisms among young men who have sex with men (YMSM) who stated that they were unwilling to try daily oral PrEP. METHODS YMSM in California were recruited through geosocial networking applications; we analyzed a subsample who stated that they were either ambivalent about trying or unwilling to try daily oral PrEP (n = 265). We used chi-square and Fisher's exact tests to determine characteristics associated with willingness to try injectable PrEP, willingness to try on-demand PrEP, and willingness to try either alternative form. RESULTS For individuals who stated that they would not be willing to try daily oral PrEP, ∼85% were willing to try on-demand and/or injectable PrEP. Individuals who reported some college or more reported greater willingness to try injectable PrEP (adjusted odds ratio [aOR]: 2.92; 95% confidence interval [CI]: 1.32-6.46), on-demand PrEP (aOR: 2.28; 95% CI: 1.06-4.90), or either method (aOR: 5.54; 95% CI: 1.78-17.22). CONCLUSION Future research should determine how to enhance uptake of emerging forms of PrEP among the individuals most at risk for HIV.

Abstract
BACKGROUND Phase III trials of long-acting injectable (LAI) PrEP, currently underway, have great potential for expanding the menu of HIV prevention options. Imagining a future in which multiple PrEP modalities are available to potential users of biomedical HIV prevention, we investigated which factors might help direct a patient-physician shared-decision making process to optimize the choice of biomedical HIV prevention method. METHODS Participants (n = 105; ages 19-63; 46.7% men of color) were former participants in a PrEP demonstration project and had taken daily oral PrEP for ≥ 12 months. Participants were given information about LAI PrEP and asked whether they would be interested in switching from oral to LAI PrEP. Participants were also asked about specific pros/cons of LAI PrEP, PrEP attitudes and experiences, and personality factors. RESULTS Two-thirds (66.7%) of current oral PrEP users would switch to LAI PrEP. Intention to switch was associated with product-level and psychosocial factors. Attitudes towards logistical factors (i.e. getting to regular clinic visits for recurring shots) featured more prominently than factors related to the physical experience of PrEP modality (i.e., concerns about injection pain) as motivators for switching. In a multivariate regression model, psychosocial factors including the emotional burden of daily pill taking, deriving a sense of responsibility from PrEP use, and self-identifying as an early adopter, were the strongest predictors of switching. CONCLUSIONS These data underscore the importance of attending not only to product-level factors, but also to the logistical and psychological experience of prevention methods for users. Findings have significant implications for the development of patient education materials and patient-provider shared decision aids.

Abstract
: Long-acting injectable (LAI) HIV pre-exposure prophylaxis (PrEP) may mitigate adherence challenges reported by young women in Southern Africa. We assessed preferences for PrEP in public-sector, primary care clinics in Swaziland. Among surveyed respondents, 75% (95% confidence interval = 65-83%) stated preference for LAI over oral PrEP; with no differences by sex, age, or sexual behavior (all P > 0.05). Notably, over 70% (95% confidence interval 58-82%) with current use of oral PrEP also stated preference for LAI PrEP.
