What a privilege to attend this forum which featured amongst others Dr Robert Grant, named one of Time magazine’s most influential people in 2012 for being the father of “treatment as prevention.” Dr Grant highlighted the observation that PrEP use in San Francisco had reached a positive tipping point in the last few years, with increasing use of PrEP. How have they come to this point?

It's been driven by:
1) PrEP research and demonstration projects being run in San Francisco
2) The FDA approval for Truvada use in PrEP, and
3) Word of mouth and the use of social media

Dr Grant also reiterated that by using an intention to treat analysis, PrEP is efficacious - the analysis shows that in order to prevent 1 HIV infection, 13 to 18 people were required to be treated. The recommendation for PrEP is for daily dosing although the data shows that if users were taking PrEP 4 times or more per week, the benefits were maximised. Daily dosing provides for a high level of protection and is forgiving of the occasional missed dose. The exciting takeaway message I took was that currently, there are Phase 2 Trials in long acting injectable PrEP, which may come to fruition around 2020.

Dr Darren Russell spoke about PrEP in Australia and the current 'lay of the land'. Importantly, he announced that the HIV Foundation Queensland was in planning to roll out an affordable access program for low-income individuals via the Foundation, to counter the social and ethical inequities of access to PrEP in Queensland. Dr Russell also 'hypothesised' that Truvada for PrEP may obtain TGA approval in the first quarter of 2016 and hopefully PBS approval in the latter half of 2017 (all going well). Watch this space!

Most importantly, this forum highlighted the social science and personal impacts of PrEP - it's ability to mitigate the fear of HIV, the empowerment of users, the circumvention of condom difficulties to prevent HIV infection. We heard both from Chris Williams an early adopter and PrEP advocate and Dr Fiona Bisshop, a PrEP prescriber at Holdsworth House Medical Brisbane.

The final word? If you are not PrEP'd for the future, you better get with the program.
