This aidsmap story covers a study that suggests increasing rates of sexually transmitted infections cannot easily be linked to PrEP. The study was presented in February at CROI.
Research to Rollout: PrEP in the Real World
The first PrEP proof-of-concept data came from the iPrEx PrEP trial in November 2010, which showed that daily TDF/FTC can reduce HIV risk in MSM and transgender women—the following July data from Partners PrEP and TDF2 showed that the same regimen can reduce the risk of HIV in heterosexual men and women.
As promising as PrEP may be, significant questions remain unanswered, chief among them being whether the efficacy that was demonstrated within the confines of a clinical trial—where people were not certain whether they were taking drug or placebo, were told that the safety and efficacy of PrEP was unknown, and in which they received extensive monitoring and support—can be translated into effectiveness in practice.
A new option exists but who needs it, wants it and how can it be delivered for maximum impact? There are a number of different research initiatives ongoing to help answer these questions: open-label extension studies, demonstration projects and bridging studies.
Demonstration Projects and Implementation Pilots
TDF/FTC as PrEP has proven effective in the context of a controlled clinical trial environment—it’s not clear yet how it might work in the real world, without the intensive support and monitoring available in a clinical trial setting.
Demonstration project and implementation pilots are designed to better understand how to optimize PrEP programming in a real-world setting. These projects will focus on what PrEP implementation looks like when it is actually delivered in a clinic setting and will collect data.

POZ reports on findings that oral PrEP works for women even with an abnormal vaginal microbiome. The research address concerns raised by some studies that suggested vaginal gels used as PrEP were not as effective among women with a microbial imbalance in the vagina.
