Long-acting injectable antiretroviral therapy (LAI-ART) is one of the latest advancements in HIV control with the potential to overcome oral ART barriers to adherence. The objective of this article is to anticipate and examine implementation considerations for LAI-ART using components of the PRISM model, a Practical, Robust Implementation and Sustainability Model for integrating research findings into practice.

    In the Long-Acting Antiretroviral Treatment Enabling Trial 2 (LATTE-2) phase 2b study, long-acting (LA) injectable cabotegravir + rilpivirine dosed every 8 weeks (Q8W) or every 4 weeks (Q4W) demonstrated comparable efficacy with daily oral antiretroviral therapy (ART) through 96 weeks in ART-naive adults with human immunodeficiency virus type 1 (HIV-1). Here we report efficacy, tolerability, and safety of cabotegravir + rilpivirine LA over approximately 5 years.

      Rich and sparse rilpivirine plasma concentration data were obtained from seven clinical studies. In total, 18 261 rilpivirine samples were collected from 986 subjects (131 healthy subjects from Phase I studies and 855 people living with HIV from Phase IIb/III studies). Doses ranged from 300 to 1200 mg, as single-dose or multiple-dose regimens (every 4 or 8 weeks).

        Since 2010, the global scale-up of antiretroviral therapy (ART) has contributed to a 50% decline in global annual deaths from AIDS-related illness, from a peak of 1.9 million in 2005 to 940,000 in 2017, highlighting the importance of ART in reducing morbidity and mortality.1 However, UNAIDS has estimated that only 77% of diagnosed persons living with HIV are accessing ART, and only 82% of patients on ART have suppressed viral loads,2 suggesting there is room for improvement in adherence.

          As with other chronic conditions, adherence to daily medications remains a challenge for many individuals living with HIV due to structural, behavioral, and social barriers. Unfortunately, high levels of adherence to antiretroviral therapy are required to maintain virologic suppression. Alternative approaches are being explored to decrease the burden of daily pill administration, including long-acting injectable, oral, and implantable products.

            Efficacy and safety of long-acting (LA) cabotegravir (CAB) and rilpivirine (RPV) dosed intramuscularly every 4 or 8 weeks has been demonstrated in three Phase 3 trials. Here, factors associated with virologic failure at Week 48 were evaluated post hoc.

              Phase 3 clinical studies showed non-inferiority of long-acting intramuscular cabotegravir and rilpivirine dosed every 4 weeks to oral antiretroviral therapy. Important phase 2 results of every 8 weeks dosing, and supportive modelling, underpin further evaluation of every 8 weeks dosing in this trial, which has the potential to offer greater convenience. Our objective was to compare the week 48 antiviral efficacy of cabotegravir plus rilpivirine long-acting dosed every 8 weeks with that of every 4 weeks dosing.

                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 toxicities and falling drug concentrations after missed doses, as well as primary and secondary resistance to current drugs and monoclonal antibodies are important considerations.
