Summary

This study tests a vaccine called AADvac1 in 146 people with progressive supranuclear palsy (PSP), a rare brain disorder that affects movement and thinking. The vaccine aims to target a protein linked to the disease and slow its progression. Participants will receive injections over time, and researchers will measure changes in symptoms using a rating scale.

What this could mean

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

Active substance
AADvac1 (a vaccine targeting tau protein)
What this could lead to
If it works, this could slow the progression of PSP, a rare and devastating brain disease, giving patients more time with better function.
What could go wrong
This is an early Phase 2 trial with only 146 people, so results may not apply to all. The vaccine may not slow the disease or could cause side effects like injection reactions.
