Question and answers on long-acting therapy with cabotegravir and rilpivirine in people with HIV

Modern ART is evolving, allowing the use of new drug formulations and alternative routes of administration to oral therapy. Long-acting (LA) cabotegravir and rilpivirine, the first fully injectable antiretroviral regimen approved for clinical use, is a test case for this new route of administration, and an innovation with implications for the quality of life of people with HIV (PWH). However, its use requires a reorganization of outpatient clinics and outpatient services, and a number of issues remain to be defined regarding the management of PWH on LA drugs, including the correct selection of people who can be treated with LA cabotegravir and rilpivirine. There is also ongoing debate about the best way to monitor both efficacy and tolerability of LA treatment and whether the management of virological failures and blips should be different from that reserved for oral regimens. The present article reviews the data on the use and management of LA cabotegravir and rilpivirine in different settings, with a review of clinical trial data and also the first available real-life experiences. The article focuses on the following: the reasons for the use of LA drugs; the implementation of their use in clinical practice; and the monitoring of treated people over time.
