Alzheimer's drug extension trial halted early — what we know
NCT ID NCT05522387
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study gave Alzheimer's patients who had already completed earlier XPro1595 trials an extra 55 to 74 weeks of the drug to check long-term safety and effects on memory and brain health. Only 11 people took part, and the trial was terminated early, so the findings are limited. The drug targets brain inflammation, but whether it helps slow Alzheimer's remains uncertain.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- XPro1595 (a weekly injection that targets brain inflammation)
- What this could lead to
- If it works, this could point toward a treatment that slows cognitive decline in Alzheimer's disease.
- What could go wrong
- The study was terminated early with only 11 participants, so results are very limited. It is unclear if XPro1595 provides meaningful benefit, and side effects remain a risk.
