Brief summary

Pre Exposure Prophylaxis eXpanded (PrEPX) is a new study that will expand the provision of PrEP to 2,600 Victorians who have a high chance of acquiring HIV. Alfred Health is responsible for conducting the study. Associate Professor Edwina Wright from the Department of Infectious Diseases Alfred Health, Monash University and The Burnet Institute will be the Chief Investigator of this study. The study is sponsored by the Victorian Department of Health and Human Services and, co-sponsored by Alfred Health and the Victorian AIDS Council. The chief research partners are The Burnet Institute and the Centre for Social Research in Health, UNSW. The aims of PrEPX are to: -Reduce the incidence of new HIV infections in Victoria, -Expand access to PrEP in Victoria, including rural and regional locations -Build capacity in the Victorian Health Service system so that the use of PrEP will become a routine option for preventing HIV infection PrEPX will start enrolling people on 26th July 2016 and run for 21 months. We will monitor the rate of new HIV infections in Victoria for a period of 36 months after the PrEPX study commences.

Interventions

Pre-Exposure Prophylaxis (PrEP) is a medication used to HIV prevention in people who do not have HIV to reduce their risk of becoming infected with HIV. Current literature recommends that PrEP is taken orally every day to minimise the risk of HIV. All participants in the PrEPX trial will be given PrEP as an intervention. The intervention used in this trial is a single pill, taken daily containing two antiretroviral medicines: Emtricitabine 200 mg/Tenofovir Disoproxil Fumarate 300 mg tablets. The

The intervention used in this trial is a single pill, taken daily containing two antiretroviral medicines: Emtricitabine 200 mg/Tenofovir Disoproxil Fumarate 300 mg tablets. There is evidence that if individuals take PrEP daily that they may reduce their chance of HIV infection by up to 99%.PrEP is recommended in individuals as long as they are at a high risk of HIV infection. Intervention adherence will be assessed by self report surveys and script collection intervals. The study duration is a maximum of 21 months, beginning July 2016 until April 2018.
