High Propensity to Switch to Long-acting Injectable HIV PrEP with Cabotegravir in a Cohort of Oral PrEP Experienced Men who Have Sex with Men in Italy.

ABSTRACT

Aim was to investigate the propensity to switch to long-acting injectable HIV pre-exposure prophylaxis (PrEP) with cabotegravir among oral PrEP-experienced men who have sex with men. Out of 377 PrEP users, 325 (86.2%) were interested (would like = 210) or considering (would consider = 115) switch to long-acting PrEP. At multivariable analysis, the odds ratio of interest in long-acting PrEP in non-adherent vs. adherent individuals to oral PrEP was 5.03 (95%CI = 1.73-14.61,p = 0.003) and of consideration 1.63 (95%CI = 0.51-5.23,p = 0.410). We observed very high propensity to switch to long-acting PrEP, particularly among non-adherent users. Rapid availability of long-acting PrEP might address unmet needs of PrEP users in Italy.
