Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)

Summary

This trial tests whether daily text messages can help HIV-negative young men who have sex with men reduce alcohol use and risky sexual behavior. Participants receive either concrete 'how-to' messages, abstract 'why' messages, neutral messages, or no message each afternoon, and report their drinking and sexual activity the next morning. The goal is to see if these prompts can lower daily alcohol consumption and HIV risk behaviors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Behavioral intervention: theory-based text messages (concrete 'how' vs. abstract 'why' vs. neutral control) delivered via smartphone
What this could lead to
If effective, this could point toward a scalable, low-cost digital tool to help young men at risk for HIV reduce drinking and risky sexual behavior.
What could go wrong
This is a pilot study, so effects may be small or not last. The intervention relies on daily self-report, which may not be accurate, and results may not generalize beyond this specific group.

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
