HIV Pre-exposure Prophylaxis Implementation Hong Kong Study


Brief description of study

While pre-exposure prophylaxis (PrEP) is widely recommended and a number of pilot studies are on-going worldwide, progress of its implementation in the real world setting has been slow, especially in Asia. This study aims to develop a service model for PrEP delivery and test its operability in the real world setting. In this implementation study, 400 individuals with high sexual risk of HIV infection who fulfil eligibility criteria would be recruited. Eligible participants would receive one year of daily tenofovir disoproxil fumarate 300mg / emtricitabine 200mg (TDF/FTC) for free. A client-initiated approach would be adopted, requiring participants to self-arrange for regular HIV/sexually transmitted infections (STI) testing. An online system would be developed to facilitate participants to plan for testing and consultation for accessing PrEP. Questionnaire at baseline and subsequent monthly follow-up would be administered to assess behaviour, monitor adverse effects and drug adherence, the latter coupled with the completion of an online diary. Testing of HIV and creatinine would be performed using point-of-care test or by phlebotomy during clinical visits. Blood samples would be collected for archiving. Around 40 participants would be invited to join an in-depth interview in the later part of the study to evaluate the service model. The main outcome measures are: PrEP service adherence, PrEP drug adherence, prevalence of drug intolerance, prevalence of unprotected sex in the study period, incidence of HIV and STI
