PrEP/PEP Strategies for HIV Prevention
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to identify the best methods to prevent HIV among young men who have sex with men (MSM). The study will evaluate various strategies, such as daily pills (oral PrEP), injections (injectable PrEP), and on-demand oral PrEP, to determine their effectiveness in preventing HIV and other sexually transmitted infections (STIs). Participants can switch between these options during the two-year study. It is suitable for HIV-negative men living in the Atlanta area who have had male partners in the past year and are willing to use a health app on their phones. As a Phase 4 trial, the treatments are already FDA-approved and proven effective, allowing participants to contribute to research that enhances understanding of how these treatments benefit more patients.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. It focuses on HIV prevention strategies, so it's best to discuss your current medications with the study team.
What is the safety track record for these treatments?
Research has shown that both daily oral PrEP and injectable PrEP are safe and effective for preventing HIV. People without HIV have safely used daily oral PrEP for up to five years, and studies indicate it is well-tolerated with no major side effects. Injectable PrEP, specifically cabotegravir, has also proven safe and significantly reduces the risk of HIV.
On-demand oral PrEP, taken only when needed instead of daily, is safe and effective, particularly for men who have sex with men. Research indicates it works well when taken before and after possible exposure to HIV.
To stop PrEP safely, it is important to know how long to continue after potential exposure to HIV. Although specific data on stopping safely isn't detailed, the focus remains on ensuring protection during and after use.
STI PEP (post-exposure treatment for sexually transmitted infections) is generally safe and well-tolerated, with patients reporting only mild side effects, if any.
Overall, these treatments are considered safe, with research supporting their use in preventing HIV and, in the case of PEP, some STIs.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about these treatments for HIV prevention because they offer diverse approaches to suit different needs. Unlike the standard daily oral PrEP, injectable PrEP provides a long-acting option, reducing the need for daily commitment. The on-demand oral PrEP offers flexibility, allowing individuals to take it only when needed around potential exposure. Additionally, the PrEP discontinuation intervention explores safe ways to stop PrEP when it's no longer necessary, and the STI PEP option provides a backup for potential exposure to sexually transmitted infections. These varied methods not only enhance convenience but also aim to improve adherence and cater to individual preferences, which could significantly boost prevention efforts.
What evidence suggests that this trial's treatments could be effective for HIV prevention?
Research has shown that taking daily oral PrEP (pre-exposure prophylaxis) can reduce the risk of contracting HIV by up to 98% when taken correctly. In this trial, participants may choose from various prevention strategies, including daily oral PrEP, injectable PrEP, and on-demand oral PrEP. Studies indicate that injectable PrEP is even more effective, working over 99% of the time. On-demand oral PrEP, taken only when needed, offers about 86% protection against HIV when used properly. Additionally, for those at risk of sexually transmitted infections (STIs), taking doxycycline as STI PEP (post-exposure prophylaxis) has reduced STI rates by 62%. These methods provide strong evidence for lowering the risk of HIV and STIs.16789

Are You a Good Fit for This Trial?
Project PEACH is for cisgender males, aged 18-45, living in the Atlanta area who are HIV-negative and have had at least one male anal sex partner in the past year. Participants must own a smartphone with data service and be willing to use a health-related app. Those enrolled in other HIV trials or without consistent contact methods are excluded.Inclusion Criteria
