Summary

This study tests whether the drug SRX246 can reduce irritability, aggression, and self-injury in adult males with Fragile X syndrome. Eighty participants will take either SRX246 or a placebo daily for up to 8 months, with regular check-ins by phone or home visits. The goal is to see if the drug improves behavior and is safe to use.

What this could mean

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

What this could lead to

If it works, this could provide a new treatment option to reduce aggressive behaviors in people with Fragile X syndrome, improving daily life for them and their caregivers.

What could go wrong
