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.

“…Together, these studies suggest high proportions of MSM in disparate settings are interested in LA-PrEP; however, these are hypothetical willingness studies, and real-world studies are needed. The logistical challenges of service delivery, uptake and adherence remain 12. Real-world choice and effectiveness should be monitored and evaluated to understand the impact of LA-PrEP on HIV prevention alongside DO PrEP as well as other prevention measures.…”

“…High effectiveness and cost were the most important features of LA-PrEP for this sample, as in other DCE among MSM,31–35 indicating these features may be critical aspects to emphasise during LA-PrEP implementation to improve uptake by US MSM. LA-PrEP (as CAB-LA) has proven to be more efficacious than TDF-based oral PrEP at preventing HIV acquisition, likely due to both pharmacokinetics and more attainable adherence (avoiding the daily burden of oral PrEP) 12. Unsurprisingly, respondents preferred an effective product.…”

“…In 2021, the FDA approved a long-acting injectable PrEP (LA-PrEP)7 after successful safety and efficacy trials 8–11. In pooled analysis, long-acting cabotegravir (CAB-LA), a version of LA-PrEP, showed a 79% reduction in relative risk compared with tenofovir disoproxil fumarate-based oral PrEP 12. Since current data are from controlled trials, real-world effectiveness and implementation evaluations of LA-PrEP are needed 12.…”

IntroductionCabotegravir long-acting injectable HIV pre-exposure prophylaxis (LA-PrEP) was shown to be safe and effective in multiple clinical trials. Increasing uptake and persistence among populations with elevated risk for HIV acquisition, especially among men who have sex with men (MSM), is critical to HIV prevention.ObjectiveThis analysis aims to understand potential users’ preferences for LA-PrEP, with audience segmentation.DesignWillingness to use and preferences for LA-PrEP were measured in HIV-negative, sexually active MSM in the 2020 American Men’s Internet Survey. Respondents answered a discrete choice experiment with paired profiles of hypothetical LA-PrEP characteristics with an opt-out option (no LA-PrEP). Conditional and mixed logit models were run; the final model was a dummy-coded mixed logit that interacted with the opt-out.SettingUS national online sample.ResultsAmong 2506 MSM respondents, most (75%) indicated a willingness to use LA-PrEP versus daily oral PrEP versus no PrEP. Respondents were averse to side effects and increasing costs and preferred increasing levels of protection. Respondents preferred a 2-hour time to obtain LA-PrEP vs 1 hour, with a strong aversion to 3 hours. Overall, there was an aversion to opting out of LA-PrEP, with variations: those with only one partner, no/other insurance or who were Black, Indigenous or People of Colour were significantly less likely to prefer LA-PrEP, while those who were Hispanic/Latino, college educated and <40 years significantly preferred LA-PrEP.ConclusionsA large proportion of MSM expressed a preference for LA-PrEP over daily oral pills. Most respondents chose LA-PrEP regardless of cost, clinic time, side effects or protection level; however, preferences varied by sociodemographics. These varied groups likely require tailored intervention strategies to achieve maximum LA-PrEP uptake and persistence.
