Results from two large-scale efficacy trials found that injectable cabotegravir (CAB-LA), given every two months, was effective as a form of pre-exposure prophylaxis (PrEP) in preventing HIV in gay men and other men who have sex with men, transgender women who have sex with men, and cisgender women. CAB-LA was developed by ViiV Healthcare and is currently used in HIV treatment. It was approved by the US Food and Drug Administration (FDA) as the first form of injectable PrEP in December 2021. This document focuses on CAB-LA for prevention, outlining what’s known and what’s next for this emerging biomedical HIV prevention strategy.

Relative Cost-effectiveness of Long-acting Injectable Cabotegravir versus Oral Pre-exposure Prophylaxis in South Africa based on the HPTN 083 and HPTN 084 Trials: A modelled economic evaluation and threshold analysis
This article from The Lancet HIV estimates the incremental cost-effectiveness of long-acting injectable cabotegravir (CAB for PrEP) compared with tenofovir disoproxil fumarate and emtricitabine (TDF/FTC oral PrEP) in South Africa, using methods standard to government planning, and determines the threshold price at which CAB for PrEP is as cost-effective as TDF/FTC oral PrEP.
