PrEP Adherence Experiences

This pilot trial will leverage "PrEP Well," an ongoing multi-level implementation strategy for providing PrEP in transgender/gender diverse (TGD)-serving contexts by integrating peer-led PrEP navigation with programming that addresses other social and structural needs of the TGD community (e.g., housing, legal, employment, gender-affirmation, primary care). PrEP Well has been implemented at the Trans Wellness Center (TWC) in LA since 2021. TWC is a first-of-its-kind community-led, trans-affirming, TGD community center made up of 5 community-based TGD service organizations that serve the local racially and ethnically diverse TGD community. Together with our community and implementation partners this NIMH-funded R34 will adapt evidence-based Skills Training in Affect and Interpersonal Regulation (STAIR) into a trans-affirming, culturally appropriate trauma treatment for TGD persons affected by HIV and violence (Trans STAIR); evaluate the acceptability, appropriateness, and feasibility of the Trans STAIR intervention (Phase 1 beta test; Aim 1); and conduct a Type 1: Hybrid Effectiveness-Implementation pilot randomized controlled trail (Phase 2 pilot RCT; Aims 2 and 3) of PrEP Well + Trans STAIR vs. PrEP Well alone to provide preliminary support for a fully powered larger multisite R01 to test the efficacy of PrEP Well + Trans STAIR.

The goal of this 12-month implementation science study is to generate the evidence required to ensure long-acting cabotegravir (LA CAB) as pre-exposure prophylaxis (PrEP) can be delivered in an equitable manner within the NHS. This study will recruit both PrEP users and healthcare professionals (HCPs). The main questions it aims to answer are: * What do healthcare providers think about the feasibility of delivering LA CAB PrEP within sexual health services in the NHS? * How many participants stay on/remain consistent with LA CAB PrEP injections at Month 12 (PrEP persistence)? Participants (200 PrEP users) will be followed for 12-months and asked to complete surveys at 3 study visits. A subset of 20 participants will also be asked to complete interviews about their experiences. We will also ask 20 HCPs at participating locations to complete surveys and interviews at both baseline and month 12. A core principle of equity (understanding any difference in impact on underserved populations) will be applied throughout the study. To ensure representation of a diverse group of participants that reflects the demographic groups most affected by incident HIV and most underserved by PrEP in the UK, enrolment targets will be applied and meticulously managed by the central study team, as follows: * A cap of 30% (n=60) will be applied to recruitment of White cisgender men who have sex with men who are not otherwise part of other under-represented groups (as defined below), * At least 70%% (n=140) of participants will represent groups currently underserved by PrEP and fall into one (or more) of the following socio-demographic categories: women (defined cisgender or transgender) OR as transgender men OR non-binary individuals OR age\<25 yrs, OR sex workers OR people who inject drugs OR racially minoritised heterosexual men.
