Strategic use of salvage long-acting antiretrovirals in the setting of resistance.

purposeLong-acting cabotegravir/rilpivirine (LA-CAB/RPV) was approved for use in virally suppressed patients with human immunodeficiency virus (HIV) in January 2021. While this was a paradigm shift for many patients living with HIV, as LA-CAB/RPV was the first injectable complete regimen for the treatment of HIV, several patient populations, including those lacking virologic suppression, have not been able to easily access this advance in science and care. SUMMARY: In this article, we provide an update on 2 patients from our previous report and describe one further patient who experienced treatment failure following initiation of LA-CAB/RPV. Additionally, we review reports published to date of the clinical outcomes of patients with viremia who have accessed LA-CAB/RPV in the setting of baseline resistance-associated mutations (RAMs) to either component and any resulting RAMs at virologic failure. On the basis of this evidence, we recommend that hybrid or all-injectable regimens be considered for patients who have struggled with adherence to oral antiretroviral therapy or have partial or full resistance to one component of LA-CAB/RPV.

conclusionThe case series reported here adds to literature supporting the notion that LA-CAB/RPV can be successfully used in patients who are viremic.
