What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of lenacapavir, an injectable medication, as a long-term option to prevent HIV. Researchers aim to determine if allowing participants to choose their follow-up care location—at home, in the community, or in a clinic—improves adherence compared to clinic-only visits. They also assess the safety, acceptability, and costs for participants. This trial suits HIV-negative individuals in Massachusetts who qualify for HIV prevention treatment and are willing to try the injectable medication and follow the study's procedures. As an unphased trial, it offers a unique opportunity to contribute to innovative HIV prevention strategies.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have a significant drug interaction with lenacapavir, you may not be eligible to participate.

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

Research has shown that lenacapavir, an injectable treatment to prevent HIV, is generally safe. Earlier studies found that both adults and teenagers using lenacapavir for PrEP (pre-exposure prophylaxis) experienced similar safety outcomes, indicating that lenacapavir is usually well-tolerated across different age groups.

Only a few safety concerns exist, mainly mild reactions at the injection site, which are common with shots. Overall, lenacapavir has been used effectively to prevent HIV without major safety issues. This information supports its safety for those considering participation in a clinical trial for lenacapavir.12345

Why are researchers excited about this trial?

Lenacapavir is unique because it offers a new approach to HIV prevention. Unlike current PrEP options that typically require daily oral medication, Lenacapavir is designed to be administered as a long-acting injectable, potentially every six months. This could significantly improve adherence and convenience for users. Researchers are excited about Lenacapavir because it targets a different part of the HIV life cycle, potentially offering a more robust barrier against infection.

What evidence suggests that this trial's treatments could be effective for PrEP?

Research has shown that lenacapavir is a strong option for preventing HIV. In one study, lenacapavir prevented HIV in 100% of women and 96% of mostly male participants. Another study found that only 0.1% of people using lenacapavir contracted HIV, a rate much lower than expected without it. These impressive results suggest lenacapavir can be a highly effective choice for HIV prevention. Participants in this trial will join either the PrEP Choice arm, where they can choose their follow-up location, or the PrEP Clinic arm, where follow-up occurs at the clinic.2678
