Brief summary

The aim of this study is to evaluate the feasibility of prescribing a medication called Truvada daily to a sample of gay and bisexual men at high risk of acquiring HIV to prevent them acquiring HIV infection. Objectives are to assess the acceptability of daily PrEP by measuring adherence to medication, average duration of taking PrEP and average study retention time for participants. We also wish to assess the behavioural impact of taking daily PrEP including sexual partnering and condom use on participants. This will involve following participants 3 monthly for STI and HIV testing, assessment of adherence to medication, recording adverse effects and will involve participants completing a behavioural on-line survey at baseline and 3 monthly. The sample size will be 150 participants and the study duration will be over 24 months.

Interventions

The aim is to assess the implementation of a novel HIV prevention intervention (PrEP or pre-exposure prophylaxis) at Auckland Regional Sexual Health Service (ARSHS) clinics to individuals at high risk of HIV infection. The purpose is reduce new HIV infections in participants. Specific objectives are to investigate: a) Acceptability of PrEP for those invited into the study; by measuring adherence; duration; retention; b) Risk behaviours on PrEP including sexual partnering; condom use; STI and H

The aim is to assess the implementation of a novel HIV prevention intervention (PrEP or pre-exposure prophylaxis) at Auckland Regional Sexual Health Service (ARSHS) clinics to individuals at high risk of HIV infection. The purpose is reduce new HIV infections in participants. Specific objectives are to investigate: a) Acceptability of PrEP for those invited into the study; by measuring adherence; duration; retention; b) Risk behaviours on PrEP including sexual partnering; condom use; STI and HIV incidence; c) Factors (socio-demographic and attitudes) associated with PrEP acceptability, adherence, retention and behaviours; d) The views and experiences of PrEP users including disclosure; stigma; sexual negotiation. Design: Open-label single-arm treatment evaluation study Gay and bisexual men who fit the behavioural inclusion criteria of being considered high-risk for acquiring HIV will be invited to participate. Participation will require written informed consent. All participants will be prescribed a fixed-dose co- formulation of tenofovir 300mg/emtrictabine 200mg(Trade name Truvada) for daily administration orally. Participants will be followed up 3 monthly for HIV and STI testing and assessment for possible adverse effects. Participants will also be rquired to complete an on-line behavioural survey at baseline and every 3 months to assess any possible behavioural impacts of taking PrEP. The sample size will be limited to 150 participants due to requirements that implementation of the study should not adversely impact on operational and budgetry requirements of the Auckland regional Sexual health Service.There will be no control group as previous studies have shown this intervention to be effective and this is intended to be a demonstration project. WHO is encouraging countries to undertake demonstration projects to facilitate understanding of the safety, effectiveness and sustainability of daily oral PrEP and its use as an addition to existing HIV prevention efforts. Study duration 24 months
