Comparison of At-Home Versus In-Clinic Receipt of Long-Acting Injectable Cabotegravir/Rilpivirine

Background: The need for frequent travel to a clinic could impair access to injectable antiretroviral therapy for persons living with human immunodeficiency virus type 1 (HIV-1) infection. We hypothesized that allowing persons receiving treatment with long-acting injectable cabotegravir plus rilpivirine (LA CAB/RPV) to receive and store the medication in their own refrigerator prior to in-home administration by a healthcare provider would be as safe and effective as receiving treatment in a clinic.

Methods: Persons prescribed LA CAB/RPV in the Infectious Diseases clinic at the Medical University of South Carolina were offered enrollment in this non-randomized, observational study between August 2021 and December 2022. After in-clinic receipt of the initial LA CAB/RPV injection, participants chose to receive each subsequent injection over the following 12-months either in clinic or at home.

Results: The 33 enrolled participants were primarily Black (64%), male (73%), and had a median age of 46. Three participants stopped LA CAB/RPV and transitioned to oral antiretroviral therapy due to allergy (n = 1), loss of virologic suppression (n = 1), and visit adherence (n = 1) concerns. A comparable number of participants received treatment primarily in clinic (n = 18) relative to at home (n = 15). Injection site pain/soreness was common (52% of injections) but did not differ between groups. There were no differences in safety or efficacy between groups and both groups reported high treatment satisfaction. All participants were virologically suppressed and retained in care at the end of the study.

Conclusions: At-home administration of LA CAB/RPV by a healthcare provider was comparably safe, effective, and associated with high participant satisfaction relative to in-clinic administration.
