PURPOSE OF REVIEW: The aim of this review was to describe future options for long-acting HIV treatment and preexposure prophylaxis (PrEP) regimens featuring both innovations with currently approved antiretrovirals and a profile of investigational agents in the pipeline. RECENT FINDINGS: Newer formulations and modes of delivery for existing antiretroviral drugs and a number of investigational agents are under study for long-acting HIV treatment and PrEP. Regimens with weekly oral dosing for HIV treatment, monthly oral dosing for HIV PrEP, and injectable agents with longer dosing intervals (every 3 months or longer) for treatment and PrEP are in clinical development. Newer agents with novel mechanisms of action and newer modes of administration including vaginal rings, implants, patches, and rectal douches also are under investigation. SUMMARY: Despite the success of current antiretroviral therapy and PrEP with one-pill, once-daily regimens, there is a continuing need for new formulations, investigational agents, and novel modes of delivery to overcome barriers to implementation and ensure real-world effectiveness. Newer long-acting antiretroviral regimens for HIV treatment and PrEP using novel preparations and strategies will offer choice, enhance adherence, decrease toxicity, and improve patient and provider satisfaction.
