Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Feasibility of LA CAB delivery (HCP perspective): Mean Feasibility of Intervention Measure (FIM) score among healthcare professionals

    Mean score on the validated Feasibility of Intervention Measure (5-point Likert scale; higher scores indicate greater perceived feasibility) assessing delivery of long-acting cabotegravir PrEP in NHS sexual health services, supplemented by qualitative thematic analysis of semi-structured interviews with HCPs.

    Month 12

  • PrEP persistence on long-acting cabotegravir: Proportion of participants remaining on long-acting cabotegravir PrEP at Month 12 without interruption

    Persistence defined as the proportion of participants who remain on long-acting cabotegravir injections at Month 12 with no documented interruption; interruption defined as two missed consecutive injections without oral bridging per Summary of Product Characteristics (SmPC).

    Month 12

Secondary Outcomes (14)

  • Acceptability of LA CAB (HCPs and PrEP users): Mean Acceptability of Intervention Measure (AIM) score

    Month 12

  • Appropriateness of LA CAB (HCPs and PrEP users): Mean Intervention Appropriateness Measure (IAM) score

    Month 12

  • Feasibility of LA CAB (PrEP user perspective): Mean Feasibility of Intervention Measure (FIM) score among PrEP users

    Month 12

  • Implementation fidelity and adaptation: Proportion of sites adhering to implementation blueprints and description of adaptations

    Baseline to Month 12

  • Adoption and penetration of LA CAB: Proportion of eligible individuals initiated on LA CAB and proportion of total PrEP users receiving LA CAB

    Baseline to Month 12

  • +9 more secondary outcomes

Other Outcomes (3)

  • HIV incidence and status: HIV incidence rate and proportion remaining HIV-negative

    Baseline to Month 12

  • Sexually transmitted infection (STI) incidence: Incidence of STIs

    Baseline to Month 12

  • Injection site reactions: Incidence and severity of injection site reactions

    Baseline to Month 12

Study Arms (3)

Existing PrEP user participants

This group will consist of participants who already have experience with taking PrEP. They will make up 85% (n=170) of the overall recruitment target for the PrEP user participants. Existing PrEP users will have a baseline visit at M0 and the next visit will take place two months later at M2, followed by visits every two months until M12

New PREP-user participants

This group will consist of participants who are new to using PrEP. They will make up 15% (n=30) of the overall recruitment target for the PrEP user participants. Those who are new to using PrEP will have a baseline visit at M0 and additional visit at M1 and the next visit will take place one month later at M2, followed by visits every two months until M12

Healthcare Professionals

This group will consist of 20 HCPs recruited from participating study sites. HCP participants will be asked to complete the following validated open-access questionnaires at baseline and M12: * Intervention Measure (AIM), * Intervention Appropriateness Measure (IAM), * Feasibility of Intervention Measure (FIM) They will also be asked to complete qualitative interviews at baseline and month-12.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The participants in this study are 1) PrEP users and 2) NHS healthcare providers (HCPs) recruited from 12 study sites (sexual health clinics and associated non-specialist service delivery sites) that currently deliver PrEP. HCP participants will include doctors, nurses and pharmacists who currently provide injectable PrEP. Note: PrEP user participants are those who are both naive (new to ) to any PrEP modality, and PrEP experienced (former or current oral and/ or injectable PrEP users), on PrEP in accordance with NHS and NICE guidelines (28).

You may qualify if:

  • Adults who are aged \> 18 years at time of consent (including people of child-bearing capacity and age, non-pregnant or pregnant adults)
  • Attending a participating NHS sexual healthcare service
  • Prescribed LA CAB for PrEP according to NICE and NHS eligibility criteria (including those newly prescribed and those already using LA CAB)
  • Non-reactive / negative HIV Antigen/Antibody test and HIV RNA test at time of LA CAB for PrEP initiation (performed under routine care)

You may not qualify if:

  • One or more reactive or positive HIV test results at enrolment visit, even if HIV infection is not confirmed.
  • Currently enrolled in interventional trial of PrEP agents, HIV vaccine trial or experimental medication.
  • Plan to relocate out of the area during the study period. Note: "Plan to relocate out of the area" is defined as a stated intention at enrolment to move residence outside the catchment area of a participating study site during the study period, such that ongoing clinical management would likely transfer to a non-participating team.
