• Demonstration project
– Clinicaltrials.gov NCT01989611

Method
• Sites
• Fiocruz
• Referral Center for HIV treatment (CRT/SP)

Method
• Individuals assessed at FIOCRUZ-RJ. CRT-SP and USP-SP

Approach • USP: participants were self-referred
• Reported Sexual Risk ( ≥ 2 male condomless anal sex partners OR ≥ 2 anal sex

Method
• Statistical Analysis
– PrEP uptake = proportion of enrolled
individuals/potentially eligible
– Chi-square tests were used to test the difference of
PrEP uptake
– Poisson regression model with robust estimate of
variance was performed to evaluate PrEP uptake
associated factors
– R was used for analysis
– Individuals who had used PrEP before (iPrEX and
iPrEX OLE) were excluded

Conclusions
• In this first PrEP demonstration project for MSM and TGW without
prior PrEP experience in a middle-income country, PrEP uptake was
high.
• Interest on PrEP was high in the MSM community.
• Targeted Trans community education activities and a Trans friendly
environment can play a major role in getting Trans people to access
PrEP services.
• The higher uptake among those at higher risk and prior PrEP
awareness emphasizes the importance of establishing strategies to
improve HIV risk perception and PrEP awareness in the MSM and
TGW communities in Brasil.
