During the presentation, Dr Pilkington described the findings: no difference in safety between daily/intermittent PrEP, males/females, or number of risk events, including bone fractures. The only noted difference to the control was a low-grade elevation in creatinine for some participants, amounting to a grade 1/2 adverse event. For creatinine rise in the grade 3/4 category, there was no difference to the control.
What does this mean for us in Australia where PrEP is available and uptake continues to be on the rise? Locally, with the confidence we are doing no harm, we can work with people at risk to develop an individualised PrEP strategy as well as encourage our colleagues to do the same. Moreover, nationally and globally we can arm ourselves with studies like this to advocate for more cost-effective ways to deliver PrEP to at-risk populations.
The lingering question is that if TDF is safe for use in PrEP, is there an imperative to halt the push for PrEP with TAF (or other drugs) in the interest of cost-saving? I think that like ART, having a menu of options allows us to cater to individual health needs, however, putting our efforts behind TDF will mean that we can focus on getting PrEP to everyone who needs it thereby increasing the reach of this amazing tablet.
