What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand how the body processes (pharmacokinetics) a single dose of two F/TAF tablets, which researchers are studying for HIV prevention. The study examines how these tablets function in the body over 14 days. Individuals in good health, who have not recently used oral PrEP, and have a non-reactive HIV test may qualify for this trial. Participants should be willing to use condoms and refrain from taking other PrEP medications during the study. As a Phase 1 trial, this research focuses on understanding the treatment's effects in people, offering participants the opportunity to be among the first to receive this new treatment.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Studies have shown that Tenofovir Alafenamide (TAF) is generally easy for most people to tolerate. Research suggests that TAF is safer for the kidneys compared to a similar drug, Tenofovir Disoproxil Fumarate (TDF), indicating it might be gentler on the body over time.

However, some considerations are important. Some people using TAF have reported weight gain. Additionally, a small percentage (2.2%) developed high blood pressure within two years of starting TAF for HIV prevention.

This study is in its early stages and aims to understand how the body processes TAF. While safety information is still being gathered, past research shows TAF is generally manageable for most people. Keep these points in mind when considering joining the trial.12345

Why do researchers think this study treatment might be promising?

Researchers are excited about Tenofovir Alafenamide (TAF) for HIV prevention because it offers a new approach compared to current options like Tenofovir Disoproxil Fumarate (TDF). Unlike TDF, TAF is designed to be more potent at lower doses, potentially reducing side effects like kidney damage and bone loss. This could make TAF a safer option for long-term use in preventing HIV. Additionally, the one-time dosing of two F/TAF tablets might offer a more convenient regimen for users, enhancing adherence and overall effectiveness.

What evidence suggests that this treatment might be an effective treatment for HIV prevention?

Research has shown that Tenofovir Alafenamide (TAF) effectively lowers the risk of HIV infection. In this trial, participants will receive a one-time dose of two F/TAF tablets. Studies have found that using TAF as a preventive measure before HIV exposure (known as PrEP) greatly reduces the risk of contracting the virus. Real-world evidence supports its high effectiveness and safety, with many users reporting high satisfaction. TAF has proven to maintain strong control over the virus. Although some studies mention higher rates of blood fat issues with TAF, its overall benefits for preventing HIV remain very promising.56789
