Transforming HIV prevention: the promise of long-acting preexposure prophylaxis in high HIV burden settings.

Purpose of Review: Recent research on efficacy and safety of long-acting preexposure prophylaxis (PrEP) holds the promise to transform HIV prevention in high HIV burden settings. We review emerging findings regarding early end-user acceptability of long-acting PrEP modalities, feasibility of integrating long-acting PrEP into health systems, and considerations regarding drug resistance and cost.
Recent Findings: Long-acting PrEP, particularly injectables, was found to be highly acceptable among individuals across key populations in high HIV burden settings. Concerns around use of long-acting PrEP highlight the importance of choice and ability to switch methods. Existing provider-level barriers to oral PrEP implementation (e.g., overburdened staff, training gaps) may impact long-acting PrEP rollout - however, utilization of PrEP implementation strategies such as task-shifting, timely PrEP training for all providers, differentiated service delivery, and integration with sexual health services, may mitigate barriers. Studies modeling injectable PrEP scale-up demonstrate substantial benefits in HIV mortality reduction, outweighing risks of increased integrase inhibitor resistance, but also highlight the urgency of pricing long-acting PrEP to ensure access and affordability.
Summary: Long-acting PrEP could be a game changer in HIV prevention in high burden settings. There is an urgent need for rapid scale production and price reductions to ensure access in high HIV burden settings. Implementation strategies are needed to address individual and provider-level barriers.
