We are currently enrolling for Impower-024:
The main purpose of the Impower-024 study is to determine the safety and efficacy (how well it works) of an HIV drug called islatravir used for Pre-Exposure Prophylaxis (PrEP). Islatravir is in a new class of HIV medications and is taken by mouth once a month. In this study, participants will receive either monthly islatravir and a daily placebo for Descovy, or a monthly placebo and daily Descovy.

- Once-a-month visits for up to 2 and a half years,

You may be eligible if:

For their time and travel, eligible participants can receive up to $125 per visit.
